PART I
Item 1. Business.
SUMMARY
Peak Bio is a clinical-stage biopharmaceutical company focused on developing innovative therapeutics addressing significant unmet need in the areas of cancer, inflammatory and rare diseases. We will continue to explore and partner with researchers, clinicians, patient advocacy groups, academic institutions, governmental agencies, and our investors to continue to expand treatment options and partnerships to meet those expectations.
In the near-term, Peak Bio will focus on its proprietary “Peak Bio R&D Discovery Toxin and ADC Platform Engine”. To achieve this, we believe Peak Bio’s management team are well suited to drive this strategic initiative, having combined 50 plus years of industry experience in drug development of small molecules, antibodies, and antibody-drug-conjugates (ADCs), and having successfully led companies that created therapeutics in above categories during their tenures. During his career, Dr. Huh, our founder and chairman has founded or co-founded companies such as pH Pharma and BridgeBio (NASDAQ: BBIO) and been a partner of McKinsey & Co (Healthcare/ Technology sector). He has held various leadership positions including Chairman at companies such as Pliant Therapeutics (NASDAQ: PLRX), CytomX Therapeutics (NASDAQ: CTMX), Geron Corporation (NASDAQ: GERN), Epizyme (NASDAQ: EPZM), Chief Executive Officer of BiPar Sciences (acquired by Sanofi) and has served on the Board of Directors for Facet Biotech (acquired by Abbott) and Nektar Therapeutics (NASDAQ: NKTR).
The company has determined that our lead clinical candidate, PHP-303, will move forward with external partnering/collaboration and are focused on identifying a strategic partner for this program.
Peak Bio has leveraged two decades of industry learnings in advancing novel payloads, an important area of the ADC field allowing for highly targeted treatments in cancer. In some indications, ADCs have replaced conventional chemotherapies and targeted therapies by delivering potent antibody-directed payloads selectively to their tumors, releasing payloads in the tumor environment via improved linker technology, avoiding the potential for significant off-target toxicities observed in systemic chemotherapies. These incremental improvements in cancer treatments for patients and specifically ADCs have also led to the growing commercial success of ADCs currently on the market and likely for those currently in development. A quick scan of the deal flow associated with ADCs over the past 5 years is encouraging both from their continued clinical and commercial success. We believe Peak Bio is well-positioned to take advantage of this field with novel payload platform driven ADC-based therapeutics.
We are poised to launch off a platform of proprietary in-house technologies that differentiate our ADCs from existing on-market and in-development antibody or ADC programs.
Why do we postulate that our approach could be a very important next step in the ADC field?
Based on the clinical and commercial successes of checkpoint inhibitors that activate immune cell mediated killing of tumors, our programs have taken the traditional approach of an ADC and added an important immunomodulatory component. In essence, we hypothesize that our combination of Antibody + Linker + Peak Bio Toxin with Immune Modulation is potentially a better ‘Mousetrap.’
Our most advanced platform in oncology utilizes our toxin, PH-1 or Thailanstatin (a spliceosome modulator) to generate a pipeline of proprietary ADC product candidates that are differentiated from traditional ADC-based therapies so that we may address unmet need in cancer patients. Differentiation is the first, and necessary step, towards the development of therapies serving an unmet need in patients. For e.g., the tumor may already be resistant to an approved ADC with payload A but may still respond to an investigational ADC with payload B, as the MoA is different. In that regard, PH-1 is a novel ADC payload and targets the proper splicing of introns. These mis-spliced RNAs are subjected to mRNA decay depriving cancer cells of thousands of essential proteins vital to survival and proliferation. In addition, PH-1 creates mis-spliced proteins or neoepitopes which the
1
immune cells can target well after the initial “chemotherapy” is delivered, in essence creating a second mechanism for cancer killing.
Our first product candidate is an ADC targeting Trop2, which is an antigen broadly expressed in solid tumors of epithelial origin. Our Trop2 ADC and other undisclosed discovery-stage ADC candidates are products of our proprietary Peak Bio R&D Discovery Toxin and ADC Platform Engine, specifically the PH-1 payloads targeting RNA splicing. We will continue to identify cancer targets that are well suited to our technology. The goal over time and with the appropriate investment, Peak Bio desires to create a series of differentiated next generation cancer therapies targeting difficult to treat cancers and contribute to increased cancer survival to the benefit of patients, care givers, our potential future partners with the added benefit to our investors.
Even though Peak Bio’s PH1 platform approach has been initiated, and our first ADC targeting Trop2 has been nominated, we are still working on two additional toxins that are in early R&D to add to our armamentarium of novel payloads. We envision the Peak Bio R&D Discovery Toxin and ADC Platform Engine of the future will conceive multiple ADCs derived from different payloads with differing and complementary MoAs.
The company’s rare disease portfolio contains a small molecule inhibitor of human Neutrophil Elastase (NE) that Peak Bio is developing for the potential treatment of a genetic disorder known as alpha-1 antitrypsin (AAT) deficiency (AATD). AATD is a life-threatening condition that results in severe debilitating symptoms, including early-onset pulmonary emphysema and liver complications. Scientific data indicate that the increased risk of lung tissue injury in AATD patients may be due to inadequately controlled NE protease activity caused by the insufficient amounts of AAT, the major antiprotease that inhibits NE activity in lungs. We believe that by inhibiting NE, PHP-303 has the potential to reduce the destruction of lung tissue and stabilize clinical deterioration in AATD patients.
PHP-303 is a selective and reversible NE inhibitor (NEI) with sub-nanomolar potency against the bioactive form of NE (von Nussbaum et al., 2015, Chem Med Chem 10:1163). This 5th generation NEI asset was in-licensed from Bayer Pharmaceuticals with a demonstrated IC50 potency of 0.65 nanomolar (highly potent) for the inhibition of human NE which Bayer had tested in phase 2 as an oral once-daily regimen (low doses) to suppress NE activity in Chronic Obstructive Pulmonary Disorder (COPD) patients.
The company has evaluated PHP-303 at higher dose levels in phase 1 human clinical trials in both single ascending dose (SAD) and multiple ascending dose (MAD) formats and demonstrated dose-dependent pharmacokinetics, pharmacodynamics, and an acceptable safety profile. The drug has been tested in nearly 186 subjects including the most recent SAD and MAD studies with largely Grade 1 or 2 treatment-related adverse effects (AEs). From pharmacodynamic perspective, the NEI achieved greater than 90% inhibition at the 10 or 20 mg dose levels and achieved the recommended phase 2 dose (RP2D). However, a Maximum Tolerated Dose (MTD) for PHP-303 was not established as the highest dose was tolerated without significant AEs (See clinical characterization of PHP-303 section below; von Nussbaum & Lee, 2015, Bioorg & Med Chem Let 25: 4370–438;4381). The pharmacokinetic profile and lack of serious AEs in our phase 1 clinical studies support a phase 2 clinical evaluation of PHP-303 as an investigational therapy for the treatment of AATD in the chronic setting.
We believe that Peak Bio and the management team are well-positioned to collaborate effectively with a potential future partner by introducing them to our researchers, clinicians, patient advocacy groups, academic institutions, governmental agencies, and provide hands-on experience/ knowledge gained during the SAD and MAD clinical studies. Thus, we can continue to address significant unmet medical need for patients with AATD, and their advocacy groups with whom we have developed relationships over the years.
At this time, we believe that the company and shareholders are best served with finding external partnerships for our clinical stage asset PHP-303 while continuing to use our resources on advancing and expanding our ADC Toolkit of novel toxins, linkers, and the ADCs the company has in play and will likely nominate new candidates in the near term horizon.
Overview
Peak Bio is a clinical-stage biopharmaceutical company focused on commercializing innovative therapeutics that aim to improve and address significant unmet medical need for patients with cancer, inflammatory and/or rare diseases. We will continue to explore and partner with researchers, clinicians, patient advocacy groups, academic institutions, governmental agencies, and our investors to continue to expand treatment options and partnerships to meet those expectations. Peak Bio will continue to grow our clinical and preclinical pipeline by executing our clinical plans for our existing program, ideally add new clinical assets through acquisition and through our internal oncology platform engine.
Our clinical stage, phase 2 ready asset, PHP-303, is being investigated for the treatment of alpha-1 antitrypsin deficiency (AATD), a rare genetic disorder and exploring opportunities with PHP-303 for the treatment of acute respiratory distress
2
syndrome (ARDS). We believe our portfolio is well diversified because our product candidates employ different mechanisms of action and target separate indications. We intend to develop and potentially commercialize our rare disease product candidates and potentially future acquired opportunities to maximize potential future sales and marketing synergies. We will also consider potentially seeking strategic partnerships and relationships for further potential clinical development and/or commercialization of these assets.
As part of our historical strategic business plan, we sought and acquired a clinical stage asset that is a small molecule, a neutrophil elastase inhibitor. As stated above, Peak Bio has made the strategic decision to focus our limited resources on our oncology portfolio (proprietary ADC platform) while ensuring that our clinical stage asset efforts are focused on strategic partnering initiatives. In addition to the Peak Bio senior management team’s business acumen and drug development and commercialization experiences across a multitude of therapeutic areas and technologies, we have maintained long-standing relationships with senior executives of large pharmaceutical, smaller biotech companies, key academic institutions, and investment banks, which we believe enhances our ability to identify and acquire additional product candidates.
We acquired PHP-303 from Bayer through our existing executives’ professional longstanding relationships with Bayer. PHP-303 products’ data package included substantial pre-clinical, clinical, and manufacturing data sets from Bayer, a well-known, well-regarded, multinational healthcare company. We have since completed two additional clinical studies (see clinical studies a Summary of PHP-303 Clinical Development Program table below), including a single ascending dose (SAD) and a multiple ascending dose (MAD) studies, that verify tolerability, and NE inhibition by PHP-303.

Our Pipeline
The following table summarizes our pipeline. We have global commercial rights to all our product candidates.
Our portfolio consists of the following product candidates:
Antibody-drug-conjugates (ADC):
Peak Bio has leveraged two decades of industry learnings in expanding an important area of the antibody-drug-conjugate (ADC) field allowing for highly targeted treatments in cancer. Despite the continued scientific advancements in the cancer field that has led to the many incremental improvements in patient cancer survival, there continues to be a need for ADCs that not only deliver antibody-directed payloads selectively to their tumors, but to also release them via improved linker technology avoiding the potential for significant off-target toxicities. Secondly, based on the success of immune checkpoint inhibitors, we believe that adding an immunomodulatory effect to our toxin(s) that engages our immune systems to assist in the cancer killing would contribute to increased tumor regression.
These incremental improvements in cancer treatments for patients and specifically ADCs have also led to the growing commercial success of ADCs currently on the market and likely for those currently in development. A quick scan of the deal flow associated with ADCs over the past 5 years is encouraging both from their continued clinical and commercial success. We believe Peak Bio is well-positioned to take advantage of this field with our proprietary ADC based therapeutics. We are poised to launch our platform of proprietary in-house technologies that enable us to design ADCs that we believe potentially offers improved ADC characteristics such as a dual mechanism of action (MoA), immune stimulation, and being refractory to multi-drug resistance (MDR)- related forms of resistance.
Antibody drug conjugates are an established therapeutic approach in oncology where an antibody is used to selectively deliver a potent toxin directly to tumor cells. The goal is to focus and maximize the ADC’s activity at the tumor site, sparing normal tissues and organs, resulting in a wide therapeutic index. There are four important aspects of an ADC approach/ program- 1) an antigen, a carbohydrate or protein moiety that is expressed preferentially on tumor cells, or cells in the tumor microenvironment contributing to its survival, 2) an antibody, a protein from the immunoglobulin family that is highly selective for seeking out the tumor antigen wherever tumor cells reside, 3) a toxin that is often a small molecule or a protein (also called
4
payload or warhead) that is 10-10,000 times more potent than conventional chemotherapy, or sometimes a chemotherapy itself and 4) a linker that serves to attach the small molecule to the antibody.
Cell-surface receptor internalization and recycling is a process that is physiological to normal and cancer cells and most ADCs that complex with target antigen receptors are internalized within the cancer cells, delivering, and releasing the payload, triggering cell death. Additionally, some ADCs also may have a feature engineered into their linkers that allow the payload to be released in the tumor environment by exploiting some feature specific to a tumor, for e.g., low pH conditions, or high tumor expression of certain enzymes such as beta-glucuronidase.
ADCs have demonstrated therapeutic efficacy in clinical trials and an increasing number of ADCs are standards of care in various hematologic and solid cancers (see below). Most ADC research has primarily focused on antigen and target discovery as opposed to payload discovery where Peak Bio is making progress.

Peak Bio antibody catalog:
We leverage our team’s deep experience and proficiency in oncology research for selecting our target antigens. If there is scientific validation from academia or industry in peer-reviewed journals or clinical validation by any form of oncology therapeutic, then these targets are given weighted preference. Here the primary focus is directed towards engineering in desired features in combination with our novel payload(s). Also, we utilize our expertise in data mining of publicly available clinical data sets to seek out under-represented targets that may be relevant to hematologic and solid cancers.
Once short-listed, we perform literature searches for published monoclonal antibodies that have been described to target those candidates. Using such information, we generate a catalog of proof-of-concept (POC) antibodies to be used in combination with our proprietary toxins to create differentiated ADCs. Where needed, we may also generate our own monoclonal antibodies in normal or humanized mice. To date, we have generated over twenty POC antibodies and expressed them in monomeric IgG format in Chinese hamster ovary cells for exploratory evaluation at laboratory scale. Using processes described above and platforms such as Oncomine and Megasampler, we have identified over 50 cancer-associated targets that we intend to evaluate with antibody-based therapeutics.
Need for new ADC Toxin strategies:
The ADC field started with the most potent toxins- for e.g., calicheamicin (Wyeth/ Pfizer). After observing the pre-clinical and clinical toxicities of these toxin warheads, the field moved down the potency scale towards the maytansines and the auristatins- monomethyl auristatin E/ F abbreviated MMAE/ MMAF (Seattle Genetics/ SeaGen), Auristatin Au101 (Pfizer)- and towards the camptothecins (Immunogen). This is where the moderate potency payload containing ADCs achieved clinical successes with multiple different targets. Those ADC programs working with the more potent toxin warheads focused on linker stability and identifying targets with low to normal tissue expression to achieve acceptable therapeutic indices.
Of the 14 ADCs that have been approved by the FDA (including accelerated approvals), eight feature microtubule inhibitors- vedotin/ MMAE (5), mafodotin/ MMAF (1), soravtansine/ DM4 (1) and emtansine/ DM1 (1); two feature topoisomerase inhibitors- govitecan (1) and deruxtecan/ DXd (1); three feature DNA-acting payloads- ozogamicin/ calicheamicin (2) and tesirine (1); and lastly, one featuring a peptide toxin from the bacterium Pseudomonas aeruginosa- pasudotox (1).
Based on published results, even after opting for lower potency, these payloads have been linked to the following toxicities in multiple approved ADCs- MMAE (neutropenia, peripheral neuropathy and gastrointestinal), MMAF (thrombocytopenia and ocular), DM1 (thrombocytopenia, neutropenia and gastrointestinal), calicheamicin (thrombocytopenia, gastrointestinal and hepatic veno-occlusive disease) and DXd (stomatitis and interstitial lung disease).
Research and investment into novel payloads are also necessary from the viewpoint of durable efficacy and reducing the potential for resistance. Like several chemotherapies, ADC payloads such as MMAE are substrates of MDR pumps (also called ABC transporters or P-glycoprotein) and MDR-mediated resistance to ADC therapy are being highlighted in scientific publications. Finally, topoisomerase I mutations associated with resistance to camptothecin/ irinotecan family of payloads have also been identified.
The above factors limit the ability of current ADC payloads to maintain durable tumor regression and reemphasize the need for new ADC payloads in drug development. We, therefore, focused on payload research, to provide optionality for our patients.
7
Our strategy was to select for a payload with nanomolar potency with sufficient cytotoxic ability and select for MoA that would include a second complementary punch to provide additional potency.
Given the clinical success of various checkpoint inhibitors, it was reasonable to hypothesize that the modulation of the innate or adaptive immune system by an ADC payload could perform this complementary, yet orthogonal function. Immune cells are nature’s defense against foreign invaders- bacteria and viruses- but fail to identify and destroy cancer cells as a) the latter are derived from self, and b) immune cells are prone to active suppression by the tumor. We leveraged our understanding of oncology, immunology, and immuno-oncology to prioritize biologies that would have this dual activity. It is this concept that we believe allows for a potentially more robust cancer therapeutic approach.
8
In theory, these dual acting payloads would have:
PH-1 family of payloads targeting splicing:
a) Biology of splicing:
In higher organisms, eukaryotes, coding regions of the genome called exons are interrupted by noncoding sequences known as introns or “junk DNA”. Genes are expressed by a two-step process. The first step called transcription that expresses deoxyribonucleic acid (DNA) as an intermediate called ribonucleic acid (RNA). It is at this intermediate step that introns are removed to generate a mature and functional mRNA molecule. The splicing machinery, known as spliceosomes, comprises five small nuclear ribonucleoprotein particles (snRNPs) that interact with more than 200 different auxiliary and regulatory factors that work in concert to precisely remove introns and connect the coding exons end-to-end and generate the final “mature” RNA. The removal of introns from mRNA is referred to as alternative splicing (AS) or simply splicing. In step two, the mature RNA is translated into various functional proteins.
Over the past 15 years, the role of alternative splicing in human disease has become apparent. When the human genome project was completed, in silico analysis predicted that at least 75% of human genes underwent splicing and that 15-50% of
9
genetic diseases were related to aberrant splicing events. With growing knowledge in the areas of algorithms that accurately predict splicing, and advances in areas of high-throughput validation of spliced protein isoforms (proteomics and immunopeptidomics), we now know that this percentage is even higher.
We now know splicing has been implicated in malignant progression of hematologic and solid tumors, enhancing development of features such as increased cell proliferation, invasion, and recruitment of tumor blood vessels. This happens in different ways:
Therefore, we hypothesized that ADC payloads targeting splicing may have the following effects:
Thus, having identified a biology for ADC payload that may simultaneously a) induce cytotoxicity by a mechanism different from conventional ADCs, and b) stimulate and activate immune cells, we turned our focus towards spliceosome modulators.
b) Thailanstatin payloads:
In nature, bacteria and fungi are the source of many toxins.
One such bacterium Pseudomonas sp. 2663 produced a small molecule toxin termed FR901464 or Spliceostatin A. FR901464 biosynthesis by Pseudomonas sp. 2663 was performed by a cluster of genes called fr9. Screening of fr9-like gene clusters in other bacteria identified a bacterium by the name of Burkholderia thailandensis MSMB43, that produced the toxin

Thailanstatin. Research groups then proceeded to purify Thailanstatins A, B and C from fermentation broth and demonstrated its cytotoxic effect on cell lines and confirmed its anti-splicing MoA.
We focused on Thailanstatin as an ideal ADC payload with the potential to induce cytotoxicity and immune activation creating two distinct ways to enhance the killing of targeted cancer cells.
Over time, we generated and evaluated a series of 13 non-natural Thailanstatin (Th) analogs through structure activity relationship (SAR) studies and optimized for potency and metabolic stability. These naked analogs were evaluated for potency and permeability against a panel of a dozen cell lines. Those analogs that were amenable to linker addition and suited for ADC development were given preference. Test conjugations of Th linker-toxin analogs were performed with clinical-grade Trastuzumab, purified to remove free toxin, and laboratory-grade ADC preparations were evaluated against a panel of Her2-high, Her2-low, and Her2-negative cell lines to determine baseline levels of ADC potency and specificity. Using this approach, we made SAR-based changes in three generations, making modifications, and optimizing for potency, stability, specificity, and conjugation ability as we went along. The first Generation yielded analog 3 (ThA3), second Generation yielded analog 9 (ThA9), and the third Generation gave us analog 13 (ThA13). Based on our results, a derivative of ThA13 was selected as our final analog.
Unlike conventional ADC toxins where linkers and toxins are separate and modular, and one linker is applied to multiple toxins for e.g., alanine-alanine, valine-valine, valine-alanine, or valine-citrulline formats; Th—compatible linkers had to be designed and then built into the synthesis route of the toxin analog. Subsequently, the synthetic route for each toxin analog and its derivative linker toxin was determined, then optimized for better yield at each step. Unlike other ADCs, where the linker and the toxin are coupled in the last steps, Th-linker toxins were assembled during the chemosynthetic process. Furthermore, where possible, we made both non-cleavable and cleavable versions of linkers (L) for conjugation to either lysine or cysteine amino acids.
The Thailanstatin ThA13 suite comprising the PH-1 family of validated linker-toxins (L-Ts) comes with a set of seven related molecules with distinct ADC features that have been extensively characterized in vitro and in vivo as Her2 ADCs:
All above ThA13 L-Ts and ADCs derived from them are collectively referred to as the PH-1 ADC platform. Stability and performance of these L-Ts has been characterized on at least two different antibodies targeting different antigens, Her2 and Trop2, yielding similar results. After proving selectivity on target-positive (vs target-negative cells), a measure of off-target activity, we tested their ability to shrink pre-implanted target-positive 200 mm3 sized-tumors in therapeutic mode. Of these, the lead L-T that yielded the maximum anti-tumor growth inhibition (TGI) in in vivo xenograft studies as a Her2 or Trop2 ADC conjugate was the non-cleavable L-T ThA13L22, later renamed PH1.
After reviewing the adverse effects associated with various non-cleavable vs cleavable ADCs for e.g., T-DM1 vs T-DXd, we concluded that PH1 ADCs in non-cleavable format are likely to be associated with fewer serious toxicities due reduced systemic exposure of the free payload. To corroborate this viewpoint, we refer to the meta-analysis performed by Wynn et al (DOI: 10.1200/JCO.2022.40.16_suppl.3032 Journal of Clinical Oncology 40, no. 16_suppl (June 01, 2022) 3032-3032) of commercially available ADCs that showed that ADCs with non-cleavable linkers were associated with significantly less toxicity than those with cleavable linkers. ADCs with cleavable linkers tended to have greater instances of >Grade 3 adverse events (AEs). 47% of patients (total 1082) treated with 7 cleavable L-Ts developed AEs > grade 3 compared to 34% of patients (total 1335) treated with 2 non-cleavable L-Ts. This was significantly different (weighted risk difference -12.9%; 95% Confidence Interval ranging from -17.1% to -8.8%). There was also a significant difference favoring non-cleavable ADCs for > grade 3 neutropenia (-9.1%; 95% CI -12% to -6.2%) and > grade 3 anemia.
We therefore decided to proceed with the non-cleavable L-T PH1 as a) our non-cleavable format was associated with better TGI conjugated to Her2 and Trop2 antibodies, b) 57% and 14% of TNBC patients treated with cleavable Trop2 ADC (Trodelvy®) presented with >Grade 3 hematologic and gastrointestinal AEs, respectively (Bardia et al 2019)., and c) non-cleavable ADCs were likely to be associated with less systemic exposure and toxicity.
Microtubule inhibitor payloads are known to induce immunogenic cell death and/ or induce anti-tumor immunity in combination with checkpoint inhibitors for e.g., MMAE in Adcetris® and Tivdak®, and DM1 in Kadcyla®. Therefore, we compared PH1 with DM1 in their abilities to induce immunogenicity over and above that of vehicle control treatment.
11
We performed an unbiased comparison of PH1-, DM1- and DMSO- treated human gastric cancer cells by RNA sequencing of all genes and looked for sequences that would give rise to aberrant proteins (neoepitopes). After identifying the normal and novel RNA species, we highlighted the neoepitope-containing species that increased in response to DM1 vs DMSO and PH1 vs DMSO treatments (red dots in figure below). As expected, DM1-treated cells contained 89 more neoepitope-containing RNA species than control, proving that microtubule inhibitor payloads are indeed immunogenic. However, PH1-treated cells contained 765 neoepitope-containing species, suggesting that PH1 payload may be highly proficient at recruiting immune cells to the tumor and impacting immune-cell mediated cancer cell death. We believe that this ability to recruit immune cells may evolve into an important future differentiator for our PH1 program and current and ensuing ADC constructs.
When we looked for genes that were negatively impacted and reduced in quantity (blue dots in figure above), we found 660 different RNA species were depleted in PH1-treated cells. Likely due to the combined effects of our payload targeting splicing with NMD-mediated degradation, these RNAs encompassed genes fueling proliferation, growth, and malignancy, and therefore, vital to the survival of the cancer cell. This was due to PH1’s global impact on splicing and largely reflected this payload’s MoA as opposed to DM1, where the payload functions by targeting microtubules.
We then evaluated PH1’s performance vs auristatins such as MMAE that are substrates of multi-drug transporter (MDR) pumps. MMAE is actively pumped out of the cancer cells, giving rise to ADC resistance. Even within the normal course of ADC administration there are concerns about increased resistance to these payloads over time and why potentially this attribute could serve as an important market differentiator.
We evaluated PH1 and MMAE’s ability to kill MES cells with normal vs high levels of MDR. We found that MMAE, not PH1, was recognized by these pumps, and the presence of high levels of these pumps reduced the in vitro cytotoxicity (IC50) of MMAE 198-fold. The presence of high levels of these pumps had no significant effect on the cytotoxic potency of PH1, as the latter were not substrates and therefore not recognized by MDRs nor pumped out of the cell. The MDR-specific inhibitor Elacridar prevented MDR pumps in MDR-high MES cells from pumping MMAE payload out of the cell, allowing its accumulation, and returning MMAE’s cell killing potency back to baseline. This finding confirmed that the loss of MMAE’s potency was specific to increase in the elevated number of MDR pumps and did not occur even in the presence of increased
12
numbers, when we blocked MDR’s ability to pump out the payload using Elacridar. This is important because MDR transporters are known to be implicated in the emergence of resistance against many chemotherapies, including some ADC payloads. Furthermore, if MDRs recognized PH1, it would have reduced its potency, and restricted its cytotoxicity to only targets that were highly expressed in cancer cells.
c) Properties of PH1 ADCs:
We used the Her2-targeted antibody Trastuzumab to tease out the differentiating properties of PH1 ADCs. As trastuzumab is an FDA-approved therapeutic, both as a naked antibody and as an ADC (trastuzumab emtansine, also known as T-DM1, or Kadcyla®), with well-published pre-clinical TGI and toxicology profiles in animal models, we decided to use clinical grade Trastuzumab for conjugation with PH1. The resulting ADC, Tras PH1, was benchmarked against Kadcyla® to determine how our payload would fare relative to microtubule targeting payload DM1 on the same antibody backbone.
When conjugated at drug-to-antibody ratio (DAR) of 3.3, Tras PH1 ADC demonstrated cytotoxic potency in the sub-nanomolar range. The ADCs were then evaluated against pre-established Her2-high expressing tumors in athymic mice; mice that lack an intact immune system to prevent rejection of human tumors. We then paid attention to the ADC dose that a) showed
13
statistically significant TGI and b) shrank established 200 mm3 tumors, and we evaluated both the short- (30-day) and the long-term or durable (5 months or more) responses of the two ADCs.
The short-term TGI of both ADCs was indistinguishable in doses ranging from 1- 15 mg/kg. Both ADCs showed statistically significant tumor growth inhibition at 1 mg/kg and both ADCs shrank established 200 mm3 tumors equally at 3 mg/kg or higher doses. The results suggested that a DAR-matched ADC containing PH1 was at least as effective as DM1 in vitro and in vivo.
When we followed the mice for extended observations, we noted that in the high-dose 15 mg/kg- treated animals, Kadcyla®-treated tumors occasionally rebounded within 3-months and Tras PH1-treated tumors rebounded in around 5 months. Tras PH1 ADC showed dose-dependent pharmacokinetics and the linker was stable in mouse circulation.
Previously, we showed that PH1 had an increased propensity to stimulate neoepitopes due to its anti-splicing MoA. To evaluate the immunogenic potential of our payload, we evaluated tumor growth inhibition in syngeneic mice with an intact immune system. We used murine MC38 colorectal cancer cells that were genetically engineered to swap out the mouse Her2 gene with its human counterpart, so that our ADCs targeting human Her2 could be evaluated in this tumor model.

Also, 15% of colorectal cancer patients are eligible to receive checkpoint inhibitor therapy and we selected this particular murine cell line as it is responsive to different immuno-oncology (I/O) therapies.
We then evaluated a DAR-matched Tras PH1 ADC with Kadcyla®, separately and in combination with checkpoint inhibitor therapy (termed I/O drug) and compared short- and long-term responses. TGI of Tras PH1 and Kadcyla® were largely similar, except for a small proportion of complete regressions observed only in Tras PH1-treated mice. As anticipated, the tumor model responded to standard-of-care I/O drug administered as a single agent.
When administered as a combination with checkpoint inhibitor therapy, the Tras PH1 ADC induced complete regressions (CRs) in 14 mice whereas 5 tumors rebounded after initial shrinkage (n=19 mice per arm). As a result, 73% of Tras PH1 + I/O treated mice showed complete regressions and were still on study at 5 months and the median survival was not reached. In Kadcyla® combination arm, there were 8 CRs, and 11 tumor rebounds, and 42% of Kadcyla® + I /O treated mice were tumor-free at 5 months. The median survival of Kadcyla® combination was 149 days.
The above results support our theory that immunostimulatory ADC payloads will induce longer and deeper responses due to greater immune cell engagement with tumor cells. In checkpoint blocked tumor cells, this deep response may require checkpoint alleviation. Also, the Tras PH1 combo-treated CR mice rejected a rechallenge with a fresh round of tumor cells, suggesting the presence of anti-tumor immunity. This immunity rejected MC38 cells with or without human Her2, suggesting that the immune response had spread beyond the original protein that the Her2 ADC targeted. This phenomenon of epitope spreading is characteristic of immune B and T cells that surveil many surrounding epitopes of the cancer cell and are not restricted to the target protein.
15
This is an advantage of immunostimulatory payloads such as PH1 that attract immune cells to the tumor. As payload delivery, and therefore cytotoxicity is directly proportional to the amount of target antigen receptors, target heterogeneity (for e.g., high-Her2 and low-Her2 expressing cells) within the same tumor is often a problem. It is likely that ADCs may not be able to deliver sufficient cytotoxic payload to kill the tumor cells with lower expression.
To solve this problem, different ADC programs have taken various approaches:
All above approaches have consequences relating to off-target cell killing.
We have focused our efforts and prefer that our payloads have inherent immunostimulatory properties that attract immune cells. Having derived from self, immune T and B cells do not have the toxicity concerns of a payload gaining access to the systemic circulation.
Our DAR-matched Trastuzumab ADC was then evaluated in non-human primates (NHP) to assess the toxicology and toxicokinetic (TK) properties of Tras PH1 ADC.
16
The Maximally Tolerated single IV Dose (MTD) of Tras PH1 ADC was 20 mg/kg. Below 15 mg/kg dose, there were no Tras PH1 ADC-related clinical signs, changes in body weight, food consumption, or clinical pathology parameters (hematology, serum chemistry). Below 15 mg/kg dose, there were no test article-related organ weight changes, nor macroscopic or microscopic histology findings. At MTD, moderate elevations in liver enzymes and moderate decreases in platelets were noted; and yet both changes were completely reversed to baseline after 10 days. These changes were also noted and published for Kadcyla® at the highest non-severe toxic dose (HNSTD) by Poon, et al.
Remarkably at MTD with Tras PH1 ADC, histology of bone marrow smears was within normal limits and there was no evidence of neutropenia by hematology. Also, no gross lesions were observed in eyes and optic nerves (ocular toxicity) and sciatic nerves (peripheral neuropathy) of animals treated at MTD with Tras PH1 ADC.
The toxicology data suggested PH1 ADCs would also be differentiated from conventional payload ADCs by toxicology parameters, in addition to pharmacology (TGI).
These findings support differentiated features, creating a pipeline of PH1 ADCs against multiple targets using our catalog of POC antibodies.
PH5 payloads targeting DNA mismatch repair (MMR) and/ or DNA damage response (DDR):
Biology of MMR:
Cancer cells are associated with uncontrolled cell division. Before cells divide, they replicate their DNA to forward one chromosome copy to each daughter cell. Largely, DNA replication is a robust process controlled by enzymes with precise fidelities, low error rates, and the presence of correction mechanisms termed DNA mismatch repair (MMR). Due to rapid and
17
frequent cell division, cancer cells tend to accumulate errors such as mutations, single-, and double-stranded DNA breaks, that are corrected in real time by MMR enzymes. Errors left uncorrected trigger a set of cellular responses collectively termed the DNA damage response (DDR). The DDR engages signaling pathways that regulate the recognition of DNA damage, the recruitment of DNA repair factors, the initiation and coordination of DNA repair pathways, and transition through the cell division cycle. If the cells are at a significant survival disadvantage, DDR processes activate apoptosis and trigger cell death.
When cancer cells are treated with DNA-damaging chemotherapeutic agents for e.g., such as the DNA alkylating agent platinum, cancer cells activate DDR and MMR processes, and when the errors are significant in terms of cellular liability and cannot be repaired, they are committed to programmed cell death.
In adult cancer patients, cancer cells are likely to be actively involved in cell division compared to normal differentiated cells. Therefore, ADC payloads that target DNA DDR and/or MMR is likely to preferentially target proliferating cancer cells. If we prevent the repair mechanisms, cancer cells are likely to be committed to cell death because of the errors they incorporate. We may even choose to accelerate the process by combining with certain chemotherapies.
Conversely, mutations in MMR and DDR genes may provide a selective advantage to the cancer cell by not correcting the mutation that would offer a significant growth or survival advantage. MMR-deficiency (dMMR) is common in many colorectal, gastrointestinal, and endometrial cancers and found in lower frequency in other solid cancers of breast, prostate, bladder, and thyroid. Here, dMMR patients can have increasing numbers of microsatellite repeats, also called high microsatellite instability (MSI-H). Both dMMR and MSI-H are considered biomarkers and predict response to checkpoint therapy and may go hand in hand with the neoepitopes that are formed when errors in DNA go uncorrected.
It is therefore likely that an ADC payload targeting MMR/ DDR biology may have a dual punch, inducing apoptosis in targeted cells on the one hand and activating the immune system by the other. This biology is compatible with Peak Bio philosophy of generating ADC payloads with multiple, orthogonal MoAs.
We are currently evaluating the first generation of PH5 linker-toxins against an undisclosed MMR/ DDR target. The toxin is bystander-enabled for killing the neighboring cell and may be adapted for low and heterogenous target expression. This is in addition to potential killing by immune activation via neoepitopes.
PH6 payloads targeting immune suppression:
Protein synthesis is integral to most biological functions. Even slow-growing, stem cell-like progenitors of tumor cells that divide less frequently synthesize proteins to support vital functions. DNA is transcribed into RNA and RNA is translated into protein. Theoretically, both inhibitors of transcription and translation may function as ADC payloads if one can partition them selectively to cancer cells using target-specific antibodies that can differentiate them from a normal cell. PH6 is an undisclosed payload that prevents protein synthesis at the stage of transcription.
Tumors containing an active population of immune cells capable of responding to immunogenic stimuli and killing cancer cells are referred to as immune “hot” tumors. Conversely, those tumors that have a low population of immune cells or have immune cells that are actively suppressed or co-opted into working for the tumor are referred to as immune “cold”. An extreme form of immune cold tumors called immune desert reflects tumors where immune cells are confined to the tumor periphery.
Immune cold tumors are hard to target and are typically unresponsive to immunotherapy. Checkpoint inhibitor therapy and immune stimulation approaches have largely been unsuccessful due the immune cells being suppressed or co-opted. These tumors have regulatory T cells (T-regs) that suppress T cell activation or express soluble factors that induce immune deserts. In this case, Peak Bio is testing payloads that a) induce cytotoxicity in tumor cells, and b) suppress immunosuppressive immune cells. This dual action protein synthesis inhibitor payload may potentially have a second function where tumor immunogenicity is increased by killing co-opted immune cells or suppressing function(s) of immunosuppressive cells.
We are currently evaluating the first generation of PH6 linker-toxins against an undisclosed target and validating its second MoA. Due to the varied effects of new protein synthesis inhibition, this toxin may also prevent the formation or recruitment of new blood vessels to the tumor.

Trop2 PH1 ADC is a Clinically validated target: Trophoblast antigen 2 (Trop2) or Tumor- Associated Calcium Signal Transducer 2 (TACSTD2) is a transmembrane glycoprotein that is highly expressed in many cancers over and above that of levels observed in normal healthy tissue, making this protein a prime ADC target. Trop2 levels are elevated in several solid tumor cancers (see table below). Trop2 overexpression in metastatic tissues makes it an attractive and potential therapeutic target for late-stage diseases.

Table from Shvartsur and Bonavida (2015) doi: 10.18632/genesandcancer.40
The Trop2 ADC approach has been clinically validated and has outperformed standard-of-care in at least two cancer settings- metastatic triple negative breast cancer (TNBC) and in Her2-negative Hormone Receptor (HR)-positive breast cancer . The Trop2 ADC Trodelvy®, also known as Sacituzumab govitecan or IMMU-132, has obtained approvals in the above indications after demonstrating significant improvement in clinical efficacy. Due to the potential of targeting Trop2 in multiple cancer settings (see table above), different companies have tried to carve out their niche using the advantages/ properties of their payloads (see table below). While Datopotamab DXd and Sacituzumab Tirumotecan are currently being tested in Phase 2 clinical trial on NSCLC and Gastric cancer patients, respectively, and have proceeded to Phase 3 clinical trials, others such as BAT8003 and PF-06664178 have discontinued their Trop2 programs for different reasons. The status of the other Trop2 ADC programs is as indicated in the table below.

The Trop2 ADCs under advanced development have topoisomerase I- targeting payloads such as the irinotecan active metabolite SN38 (Trodelvy®), deruxtecan (DS-1062), and belotecan (SKB264).
Members of the camptothecin family of topoisomerase inhibitors such as irinotecan/ SN38 and topotecan are substrates of the MDR family of transporters and may be pumped out of the cancer cell, giving rise to resistance. Non-transport mechanisms of resistance have also been described wherein patients under Trodelvy® therapy for 6 months had progressed due to resistance mutations in the topoisomerase I (Top1) gene. In a study performed at Massachusetts General Hospital, Top1 mutations such as E418K and -p.-122 frameshift rendered cancer cells refractory to topoisomerase inhibition, and Trop2 T256R mutations reducing cell surface translocation of Trop2, resulted in resistance to Trodelvy® therapy and metastasis to liver and peri-aortic lymph nodes. Since our payload has a different MoA, it will not be subject to these topoisomerase-specific forms of resistance.
Furthermore, the immunostimulatory properties of the PH1 payload may induce:
Properties of Peak Bio Trop2 PH1 ADC:
After evaluating the Trop2 ADCs that are currently FDA-approved or heading towards approval in clinical trials, we investigated the potential of a differentiated Trop2 PH1 ADC with favorable resistance and immunogenicity characteristics from PH1 payload.
22
We optimized a fully- humanized antibody that was selective for the human and non-human primate versions of Trop2 but did not recognize rodent forms of Trop2. While compatible with evaluation of cytotoxic potency in vitro and evaluation of anti-xenograft tumor growth inhibition in athymic mice, this meant we had to engineer mouse cell lines with human Trop2 to test the immunostimulatory MoA in syngeneic mice models.
Since our antibody did not recognize rodent Trop2, standard evaluations of body weight loss in rodent models such as mice and rats would not provide meaningful toxicology data other than to reflect uncoupling of the payload from the ADC. The NHP model would provide the relevant toxicology data.

Even without the immunostimulatory mechanism, our investigational Trop2 PH1 ADC demonstrated nanomolar cytotoxic potency against cancer cells in vitro. In a parallel arm of the same study, cisplatin, a conventional chemotherapy exhibited micromolar cytotoxic potency. Also, these studies demonstrated that the potency of our Trop2 ADC was specific to the target and did not kill lung cancer cell lines that lacked Trop2. This is important to prevent off-target effects of our ADC against normal cells that lack Trop2.
As previously mentioned in our Thailanstatins section, PH1 belongs to the lysine non-cleavable class of payloads and was specially selected to reduce off-target effects of our Trop2 ADCs. While Trop2 is elevated significantly in solid tumors, there is small yet significant Trop2 expression in normal lung epithelium, prostate, skin, tongue, and salivary glands. This may be relevant as stomatitis (inflammation of the tongue and mouth) was observed as the dose-limiting toxicity in the TROPION PanTumor01 clinical trial for DS-1062. This meant that in addition to preventing off-target effects in our Trop2 PH1 ADCs, we may have to mitigate potential on-target effects.
In PH1, we selected a payload that potentially prevents reduced on and off-target effects by generating metabolites that are impermeable to neighboring cells. The low expression of Trop2 in normal tissue, potency range of PH1, and impermeability of generated active payload species are designed to limit the side effects of incidental Trop2 targeting with our ADC. Trodelvy® and DS-1062 are both bystander-enabled to extract maximal tumor cell killing. However, the payload’s function in Trop2 PH1 ADC is to stimulate initial tumor debulking, induce neoepitopes and stimulate the immune system whereupon the immune-mediated cell-killing MoA would kick in. In addition to opting for a non-bystander payload, we also opted for lower drug-to-antibody (DAR) ratio of 4 to reduce on-target toxicity to normal cells. By not opting for chemical bystander activity and by opting for lower DAR, we introduced control elements to differentiate our ADC program from a toxicology standpoint. Heterogenous Trop2 expression in cancer tissue would be addressed by immunostimulatory and epitope-spreading features of PH1 described previously.
Further supporting our hypothesis, not only did our cysteine and lysine cleavable Trop2 ADC versions kill cancer cell lines non-specifically i.e., they had higher baseline activity against non-target cells, but also had lower TGI in vivo in animal models. Therefore, our best strategy was to allow toxin accumulation within the target cell and have an inactive or impermeable payload species when released by lysed target cells. The active payload species of PH1 ADCs such as the Trop2 PH1 ADC would only be “cytotoxic” when internalized as an ADC by the target cancer cells, and impermeable as the active payload species to neighboring cells or other organs when in blood circulation, further reducing the potential for off-target effects. We therefore decided to
23
proceed with PH1 for the Trop2 ADC program and tested low DAR ADCs for TGI against human tumors in animal xenograft models.
To demonstrate target-specific killing of cancer cells, we compared the cytotoxic potency of our Trop2 PH1 ADC with an ADC made from an isotype control mAb (not targeting Trop2) conjugated to the same PH1 L-T at a similar DAR, against gastric, pancreatic and bladder cancer cell lines. As the isotype antibody targets viral proteins and is characteristically absent on cancer cells, the wide margin between on-target and off-target killing against all above cell lines can be attributed to the stability of our linker. In this context, if the linker fell apart on Trop2 PH1 and Isotype control ADCs, it would release the toxin and kill the cells whether Trop2 was present on the cells or not, and this would be observable as activity for the Isotype PH1 ADC.
As Trop2 expression is mainly observed in cells of epithelial origin, we evaluated the cytotoxic potency of our Trop2 PH1 vs Isotype PH1 ADC and found no significant killing against normal human fibroblasts. Some cell death was observed upon confluence in all cell lines and occurred even on untreated cells.
24
Trodelvy® is the first-in-class Trop2 ADC with an acid-labile carbonate linker. It was included as an experimental arm in the above cytotoxicity assays and demonstrated potent in vitro activity against gastric, pancreatic and bladder cancer cell lines. Trodelvy® showed some off-target killing against normal human fibroblast cells in this setting.
To further corroborate our in vitro observations, we evaluated Trop2 PH1 ADC and Trodelvy® against the same Trop2high gastric carcinoma cell-line derived xenograft (CDx) grown as tumors in mice. For the studies to translate to a clinical setting, Trodelvy® (DAR 7.6) was administered on Day 1 and Day 8 as 10 mg/kg doses (QWx2). Trop2 PH1 ADCs at lower DARs (2 and 4) were tested only at 3 mg/kg. This was purely to evaluate the TGI from the Trop2 PHI ADC’s cytotoxic MoA alone in the absence of PH1’s immunostimulatory MoA, in xenograft tumor-bearing athymic mice lacking an immune system. The purpose of the experiment was to evaluate whether Trop2 PH1 ADC’s first MoA alone was sufficient for TGI in Trop2high expressing tumors.
When administered in therapeutic mode, against pre-established tumors of 200 mm3 size, all three ADCs induced tumor regression between 3-6 weeks. The TGIs for 10mg/kg Trodelvy®, 3mg/kg Trop2 PH1 ADC (DAR 2) and 3mg/kg Trop2 PH1 ADC (DAR 4) were 79 + 2.1%, 80.5 + 1.8%, and 87.7 + 1.0% at 21 days and 83.3 + 2.4%, 78.5 + 3.2%, and 90.3 + 1.8% at 41 days, respectively. At these times, the TGI associated with the Trop2 PH1 ADC (DAR 4) arm was significantly different from the Trop2 PH1 ADC (DAR2) and Trodelvy® arms (p<0.05) and is indicated in the table.

Upon extended observation, some tumors from each arm rebounded across all treatment groups, Trodelvy® and Trop2 PH1 ADCs. Around 2 months after treatment, 80% of Trodelvy®-treated tumors rebounded, until finally, only 20% of the mice showed significant tumor regression at 5+ months. 50% of Trop2 PH1 ADC (DAR4) showed tumor regression at 5+ months and 50% of Trop2 PH1 ADC (DAR2) showed stable disease in the same time frame with their tumors failing to grow past 400 mm3.
We conclude that Trop2 PH1 ADC has effective TGI at low DAR and dose even without PH1’s immunostimulatory MoA. Tumor cells that escape treatment tend to rebound. This is why we had envisioned the second immunostimulatory MoA when we conceptualized PH1.
To determine whether Trop2 PH1 ADC had retained the immunostimulatory activity characterized previously on PH1 payload alone or demonstrated by our POC Tras PH1 ADC, we evaluated the combination of the DAR4 Trop2 PH1 ADC with checkpoint inhibitor therapy against a syngeneic bladder cancer (urothelial) mouse model.
25
First-line checkpoint inhibitor therapy is standard-of-care (SOC) for platinum-ineligible patients that have recurrent, resistant, or metastatic urothelial cancer. Also, Trodelvy® is approved for treatment of metastatic urothelial cancers. Therefore, we used a urothelial model that was sensitive to checkpoint blockade and evaluated whether Trop2 PH1 ADC combination would result in an improvement upon SOC in this syngeneic mouse model.
In these studies, Trop2 PH1 ADC showed single agent tumor growth inhibition that was equivalent to SOC for bladder cancer. At day 14, the combination was significantly superior in terms of TGI (p=0.01) and prolonged overall survival (OS) (p=0.013). Therefore, like the POC Tras PH1 ADC, our Trop2 PH1 ADC retained the ability to combine with checkpoint inhibitors and prolong OS.
To further de-risk our program, we performed toxicology studies in non-human primate model and determined the tolerability of our Trop2 PH1 ADC in NHP. We evaluated our ADCs at DARs of 2 and 4 and performed a repeat-dose study wherein three ADC doses were intravenously administered every 3 weeks followed by a 3-week recovery period. For an idea of maximal cumulative effects, animals were evaluated 2 days after receiving all 3 doses. Reversibility was addressed in another set of animals that received all 3 doses but were allowed a 3-week recovery period. As Trop2 PH1 ADC was a likely candidate for pipeline nomination, histopathology was performed unilaterally for all tissues in both sets of animals.
3 x 6 mg/kg Q3W doses of both DAR2 and DAR4 Trop2 PH1 ADCs were well tolerated without clinical signs or body weight loss. In these treatment groups, a mild increase in liver enzymes and mild decrease in platelets were noted that reset to baseline within 7-10 days of administration of each dose. Histological evaluation of the bone marrow revealed no evidence of reduced cellularity (no bone marrow toxicity), although an altered myeloid:erythroid ratio was noted. The latter finding was probably due to the MoA of PH1 that induces an anti-tumor myeloid response. There were no other histologic findings below MTD.
At the >MTD of 18 mg/kg for Trop2 PH1 ADC, we did not observe the pathologies associated with other Trop2 ADCs in the clinic- e.g., neutropenia, gastrointestinal-, oral (stomatitis)- or lung- lesions with fibrotic or cellular infiltrates indicative of ILD were characteristically absent from our findings. Our NHP data suggests our Trop2 ADC is likely to be differentiated from a toxicology standpoint, in addition to pharmacology.
26
Unmet need and epidemiology
There is significant unmet need in Trop2-expressing cancers as is illustrated in the table below. Currently, the Trop2 ADC Trodelvy® has been only approved in TNBC and Her2- HR+ breast cancer and has accelerated approval in bladder cancer. Early indications in phase 2 clinical trial suggested DS-1062 improved Progression-Free Survival (PFS) in in non-squamous NSCLC patients. Similarly, phase 2 data suggest SKB264 improved PFS in the Gastric cancer setting. Restricting ourselves to current indications in which Trop2 ADCs have FDA approvals (Trodelvy®) or have advanced phase 1/2 data in (DS-1062/ SKB264), the number of annual deaths worldwide and in USA alone account for 2.28 million and 117,733 patients, respectively (assuming 15% and 60-70% of all breast cancers are TNBC or Her2- HR+, respectively, and 56% of all lung cancers are Non-squamous NSCLC in the table below). Prior to Trodelvy®’s approval in 2020, these patients did not benefit from standard-of-care in these indications. Therefore, there is significant unmet need in Trop2-expressing cancers based on these three indications alone.
Since Trop2 expression is elevated in multiple solid tumors, there is untapped clinical and market potential of expanding the scope of Trop2 ADC therapies to reach a wide number of cancer indications. We cannot predict the total number of patients current and future Trop2 ADC therapies may expand to; however, at maximum, Trop2 ADCs may have the potential to impact the lives of 13 million cancer patients annually.

Our Preclinical Development Programs
We have evaluated multiple targets for our second candidate PH1 ADC. We are currently performing target validation for an ADC2 program against target M5. We may generate our own proprietary mAb against target M5 in humanized mice.
We are also in the process of evaluating the first Generation of two new research-stage toxins PH5 and PH6. These platforms may need optimization and need further structure-activity-relationship (SAR) studies requiring a second or third generation to be viable payloads for the Peak Bio pipeline.
27
Time and resource- permitting, we have identified additional opportunities utilizing our teams’ expertise to expand our portfolio by developing other modalities such as bispecifics and antibody-PROTACs. These are currently in early validation stages.
PHP-303: PHP-303 is a potentially novel, oral, once daily, small molecule inhibitor of Neutrophil Elastase (NE) that Peak Bio was initially investigating for two indications, AATD and ARDS. As mentioned above, Peak Bio is strategically exploring external partnerships and opportunities to further develop the PHP-303 asset. PHP-303 (or BAY-85-8501) was licensed from Bayer, who previously conducted multiple non-clinical and clinical trials summarized below. These data support a potential clinical application of PHP-303 for treatment of patients with AATD, a genetic disorder that may result in lung or liver disease, or for ARDS. In 2021, we received a non-dilutive preclinical grant from the Department of Defense to explore PHP-303 treatment for COVID-19- related ARDS to support advancing PHP-303 potentially in this second clinical indication.
AATD is a potentially life-threatening, rare, under/mis-diagnosed and under-treated, genetic condition caused by a lack of the antiprotease alpha-1 antitrypsin, a protein that protects the lungs from enzymatic degradation by endogenous proteases. The disease manifests as early-onset pulmonary emphysema, caused by irreversible destruction of lung tissue supporting normal gas exchange (https://www.lung.org/lung-health-diseases/lung-disease-lookup/alpha-1-antitrypsin-deficiency/learn-about-alpha-1-antitrypsin-defiency). There are an estimated 70,000-100,000 patients in the United States and 120,000 patients in Europe with severe AATD (https://www.rarediseaseadvisor.com/disease-info-pages/alpha-1-antitrypsin-deficiency-epidemiology-aatd; Torres-Duran et al. 2018, Orpha J of Rare Dis 13:114). PHP-303 is designed to selectively inhibit the neutrophil enzyme called Neutrophil Elastase or NE, which is the major protease protecting lung tissue from destruction.
The graphic below highlights potential disease areas for NEIs such as PHP-303. The unchecked imbalance of protease-antiprotease that occurs in many disease states is depicted, and in addition to AATD, it highlights ARDS as another potential disease indication for PHP-303. We will explore PHP-303 as an investigational therapy for ARDS pending demonstration of preclinical benefit or alleviation of ARDS-related complications in preclinical models under the purview of the DOD grant, or other sources of non-dilutive funding.
Acute Respiratory Distress Syndrome (ARDS) is a serious lung condition characterized by acute, diffuse, inflammatory lung injury resulting from a range of predisposing etiologies (https://www.uptodate.com/contents/image?imageKey=PULM%2F58759 Gonzales et al., 2015 June 4, Austin J Vasc Med 2:1). ARDs generally progresses from a stage of damage or compromise to the “gas (air)” exchange units called alveoli to a state of lung fibrosis and scarring that happens after the body’s repair and inflammatory response kicks in. Typically, ARDS impacts 64.2- 78.9 cases/100,000 people in the US with 75% of these patients presenting with moderate to severe disease resulting in an increase in morbidity, mortality and healthcare costs. (reviewed in Diamond et al., 2021, Acute Respiratory Distress Syndrome – StatPearls—NCBI). The COVID-19 pandemic had led to an increase in the incidence of ARDS in a significant number of hospitalized COVID-19 patients (Gibson et al., 2020, Med J Aust 213:54).
Neutrophils are one of the first immune cells to be recruited to a site of an infection or tissue damage (Brinkmann et al., 2004, Science 303:1532; Potey et al., 2019, J Pathol, 247: 67; Rosales, 2018 Front Physiol, 9: article 113). Neutrophils use
28
secreted and cell-associated proteases such as Neutrophil Elastase, NE, to help degrade connective tissue allowing neutrophils to move about freely and reach sites of infection. Neutrophils contribute to killing of pathogens by 3 mechanisms: by directly engulfing them via phagocytosis, releasing destructive proteolytic enzymes that degrade bacteria via degranulation, and by releasing Neutrophil Extracellular Traps (NETs). NETs are large webs containing cell-free DNA and proteases from dead/ dying and inflammatory cells that both form a physical barrier by localizing the spread of pathogens and destroy them through action of concentrated proteolytic enzymes. This process is termed NETosis. In heightened pro-inflammatory states, as occurs in patients with COVID-19- associated ARDS, neutrophils and NETosis become dysregulated (Janoff 1985, Am Rev Respir Dis, 132:417-433; Barnes et al., 2020; Pechous, 2017, Front in Cell and Infect Microbio|, 7: Article 16). By overwhelming the body’s endogenous antiprotease balance, NETosis results in further lung damage activating platelets, their coagulation, contributing to thrombosis or blood clotting in lungs.
We believe the inhibition of NE has the potential to protect AATD and ARDS patients from further lung damage by decreasing the impact of high NE tissue concentrations that are insufficiently opposed by endogenous antiproteases. In AATD, the body is unable to produce adequate levels of AAT for sufficient inhibition of NE. In ARDS, NE production and release overwhelms endogenous antiprotease activity leading to tissue damage. Thus, both diseases are, at least in part, due to an overabundance of NE in the lung that causes damage. It is reasonable to hypothesize that a selective NE inhibitor such as PHP-303 may inhibit this excess NE and may potentially alleviate symptoms of AATD and ARDS patients. Furthermore, since NE is required for the production of NETs, an NEI may decrease the NETosis in ARDS patients potentially alleviating lung injury and/or thrombosis.
Supporting the above rationale in AATD, a comparator’s NEI demonstrated significant reduction in biomarkers desmosine/ isodesmosine and Aa -Val360. Desmosine and isodesmosine are by-products of mature elastin breakdown, proteins that crosslink mature elastin fibers in lung connective tissue and that contribute to viscoelasticity of lungs; their elevation is linked to impaired lung function. Similarly, Aa-Val360, a product that is formed when NE acts on the blood clotting factor fibrinogen and elevated levels of Aa-Val360 is correlated with COPD and emphysema. Recently desmosine/ isodesmosine and Aa-Val360 levels were accepted as surrogate biomarkers reflecting disease severity of AATD patients in the phase 2 ASTRAEUS trial, paving the regulatory path forward for future trials for NEIs (https://www.atsjournals.org/doi/abs/10.1164/ajrccm-conference.2023.207.1_MeetingAbstracts.A2844; https://www.atsjournals.org/doi/abs/10.1164/ajrccm-conference.2024.209.1_MeetingAbstracts.A1211). Currently, Peak Bio has approved Clinical Trial Applications in the UK and Ireland with all approvals necessary and may or may not need to update these protocols in light of these new developments in US regulatory pathway. Additionally, we have a relationship with and a research agreement with the Alpha-1 Project Foundation. We believe that patient advocacy groups will assist in patient access, and unite clinicians, thought leaders and patients for our future clinical trials.
Preclinical studies characterizing PHP-303 in models of acute lung injury and COVID-19 infection were funded by the US Department of Defense (DoD). These studies will inform the role of NE and NETosis in COVID-19 and non-COVID-19 associated ARDS.

PHP-303 has been studied in five phase 1 clinical trials in healthy subjects, exploring a range of doses and schedules and one phase 2 clinical trial in patients with non-cystic fibrosis bronchiectasis (NCFB). Please refer to the table above.
Clinical characterization of PHP-303
186 subjects have been exposed to one or more doses of PHP-303, and the data shows that PHP-303 was tolerated with no serious AEs (SAEs) reported. PHP-303 is rapidly absorbed in the fasted state, where median peak concentrations of drug were achieved in < 1 hour and half-life was in the range of 110 to 175 hours. Exposure pharmacokinetics appeared to increase proportionally with increasing dose to 40 mg. With multiple dosing, steady-state concentrations are reached by Day 21. Food delayed the rate of absorption of PHP-303 and therefore moderately decreased maximum serum concentration, but there was no effect on overall exposure to PHP-303. PHP-303 administered in an oral, daily schedule causes inhibition of NE, suggesting potential benefit in several NE and/or NET mediated diseases including AATD and ARDS.
PHP-303 tolerability and adverse effects
The phase 1 clinical studies were not designed to evaluate statistical significance on clinically approvable endpoints. The phase 2 clinical study results and analysis are described in (Watz et al., 2019, Pulm Pharmacol Ther, 56:86). Some 186 subjects have received one or more doses of PHP-303 in clinical studies conducted by Bayer and Peak Bio. These include 141 healthy volunteers and 45 subjects with Non-Cystic Fibrosis Bronchiectasis (NCFB). Doses studied range from 0.05 mg to 20 mg daily, with maximum study duration of 28 days. No SAEs have been attributed to drug administration in this program. Across all studies, 84 drug-related adverse events were reported. The most commonly reported AEs observed across clinical studies of PHP-303 include headache, nasopharyngitis, and cough. There was no apparent dose relationship to the reported adverse events and subjects who received placebo had similar frequencies and types of adverse events. Mild, sporadic, and transient elevations in liver function tests (LFTs), lipase, and CPK were uncommonly observed, but these events did not appear to be drug related.
31
Confirmation of NE inhibitory effect of PHP-303 in vivo
In study 16332, Bayer evaluated whole blood NE activity using an ex vivo zymosan challenge assay. Zymosan is a yeast cell wall component that activates neutrophils and release of NE. Samples were collected at baseline and several time points after dosing and induced with zymosan to determine NE levels/ activation status.
PHP-303 resulted in dose and time-dependent inhibition of human NE activity. Repeated dosing at 0.3, 0.6 and 1mg dose levels achieved and exceeded 50% NE inhibition at the lowest or trough concentration (Day 14 pre-dose) at all tested dose levels. This regimen achieved 90 to 100% maximal inhibition after the last dose at the mid and high dose levels. Importantly, daily dosing of PHP-303 at doses of 0.5 mg or 1.0 mg achieved > 24-hour(s) inhibition of NE. Similar systemic inhibitions of NE activity were also observed in Bayer Phase 2a Study 16359 in NCFB patients.

Peak Bio (pH Pharma) Conducted Phase 1 Clinical Trials with PHP-303
To better characterize and improve the chances for future clinical success, Peak Bio, (pH Pharma) tested elevated drug levels in follow-up Phase 1trials at single ascending doses (SAD) and multiple ascending doses (MAD), after acquiring the asset from Bayer. The studies reconfirmed that PHP-303 was tolerated with mainly Grade 1 AEs reported in either study. In both studies dose proportional PK exposure was observed. Dose-dependent NE inhibition was greatest in the 10 and 20 mg cohorts and steady state was achieved between 11 and 18 days in the MAD study.

Pharmacodynamic correlation of PHP-303- treated Healthy/ Obese patients with Inhibition of Neutrophil Elastase Activity
As expected, elevated dose levels of the NE inhibitor were correlated with lower NE Activity. Sustained, dose-dependent suppression of NE activity was observed and appeared to be more complete at doses >5mg. The 10-20 mg dose levels may be
34
tested in future Phase 2 trials as these MAD cohorts demonstrated greater than 90% NE inhibition over a 24-hour period. Since PHP-303 induced NE blockade was associated with rapid onset < 2-4 hours, the drug was tolerated with largely low-grade adverse events, the results suggest that PHP-303 may be suitable for long-term therapy in a chronic disease setting such as AATD.

Peak Bio Clinical Trial/Program Status
While Peak Bio is currently planning on partnering this program, the company still has approved Clinical Trial Applications in both UK and Ireland for planned Phase 2 trials in AATD patients. Any future/ potential strategic partners may need to have additional conversations with above regulatory agencies in lieu of the accepted biomarkers by the US FDA. The specific gene mutation responsible for AATD disease is mainly found in individuals of Scandinavian origin, thus we were considering Western Europe and North America for commercialization. While Peak has not filed applications for clinical trials in the US or Canada, the company is maintaining an active IND with the FDA and maintaining approved CTAs in UK/ Ireland for our patients with unmet medical need and to facilitate our future partners. Given the affected population, the future clinical development and commercialization of PHP-303 is likely to be regulated by agencies such as the Medicines and Healthcare Products Regulatory Agency (MHRA) in the UK, the European Medicines Agency (EMA) for countries in the European Union/ EU, the Food and Drug Administration (FDA) in the US and/or other national authorities such as Health Canada.
In addition to being able to launch off a platform of approved CTAs and INDs, Peak Bio believes that AATD is a rare disease and may be recognized with an Orphan Drug Designation by US FDA and by the EU. If a future partner is able to obtain FDA approval, PHP-303 may be eligible for benefits of an Orphan Drug Designation that are potentially afforded to developing this program in AATD.
Ongoing healthcare legislative and regulatory reform measures may have a material adverse effect on our business by impacting our ability to partner this clinical stage asset. Changes in regulations, statutes, or the interpretation of existing regulations governing the regulatory clearance or approval, country specific healthcare cost-containment initiatives, manufacture, and marketing of regulated products, or the pricing, coverage and reimbursement, thereof could impact eventual market approvals, uptake/acceptance/sales of a given product in the future.
Manufacturers and their facilities are required to comply with extensive FDA and comparable foreign regulatory authority requirements, including ensuring that quality control and manufacturing procedures conform to cGMP regulations. Upon transfer of SOPs and CTAs to potential future partners they will be responsible for and required to maintain all aspects of regulatory compliance including but not limited to quality assurance, manufacturing, risk evaluation and mitigation strategies, submissions of safety and other post-marketing information and reports and registration. The FDA may impose consent decrees or withdraw approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market. The above factors may impact Peak Bio’s revenue from any future out-licensing of PHP-303.
To balance the above risk(s), “Orphan drug” status is highly sought after as it adds a 7–10-year exclusivity period for drug sales and profitability. It does not help that an Orphan drug and rare disease populations are defined differently in different countries. Under the Orphan Drug Act of 1983, the FDA may designate a product candidate as an orphan drug if it is intended to
35
treat a rare disease or condition, which is generally defined as having a patient population of fewer than 200,000 individuals in the US, or a patient population greater than 200,000 in the US where there is no reasonable expectation that the cost of developing the drug will be recovered from sales in the US. To obtain orphan designation in the European Economic Area, or EEA, the product must fulfill certain challenging criteria. Under Article 3 of Regulation (EC) 141/2000, a medicinal product may be designated as an orphan medicinal product if it meets the following criteria: (1) such product is intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition; (2) either the prevalence of such condition must not be more than five in 10,000 persons in the EU when the application is made, or without the benefits derived from orphan status, it must be unlikely that the marketing of the medicine would generate sufficient return in the EU to justify the investment needed for its development; and (3) there exists no satisfactory method of diagnosis, prevention or treatment of such condition authorized for marketing in the EU or if such a method exists, the product will be of significant benefit to those affected by the condition, as defined in Regulation (EC) 847/2000.
Additionally, Peak Bio’s future out-licensing revenue may also be impacted even the partner receives a US, MHRA and/or EMA orphan drug designation, we may not be able to realize the benefits of such designation, including potential marketing exclusivity of our product candidates, if approved. Regulatory agencies are in no obligation to grant orphan drug designation to our product candidates even if product candidates of other companies have been granted the same for the treatment of AATD. Generally, if a product candidate with an orphan drug designation receives the first marketing approval for the indication for which it has such designation, the product is entitled to a period of marketing exclusivity, which precludes the FDA or foreign regulatory authorities from approving another marketing application for a product that constitutes a similar medicinal product treating the same indication for that marketing exclusivity period, except in limited circumstances. The applicable period is seven years in the United States and ten years in the EEA. The ten-year period of market exclusivity in the EEA can be extended by a further two years if the product qualifies for a pediatric extension but can be reduced to a period of six years if the orphan designation criteria are no-longer met after the fifth year. Even if orphan drug exclusivity was obtained for a product candidate, that exclusivity may not effectively protect the product candidate from competition because different drugs can be approved for the same condition in the US or EEA. Even after an orphan drug is approved, the FDA or EMA may subsequently approve another drug for the same condition if the FDA or EMA, as applicable, concludes that the latter drug is not a similar medicinal product or is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care.
Accordingly, our future revenues could be harmed by a variety of factors, including: economic weakness, including inflation, or political instability in varying economies and markets; differing regulatory requirements for drug approvals in non-European Union (EU) countries; differing jurisdictions could present different issues for securing, maintaining, or obtaining freedom to operate for our intellectual property in such jurisdictions; such jurisdictions; potentially reduced protection for intellectual property rights; difficulties in compliance with non-US laws and regulations; changes in non-U.S. regulations and customs, tariffs, and trade barriers; changes in non-U.S. currency exchange rates of the USD and currency controls; changes in a specific country’s or region’s political or economic environment, trade protection measures, import or export licensing requirements or other restrictive actions by the USA or non-U.S. governments; differing reimbursement regimes and price controls in certain non-U.S. markets; negative consequences from changes in tax laws; compliance with tax, employment, immigration, and labor laws for employees living or traveling outside of the USA; business interruptions resulting from geo-political actions, including war and terrorism, health epidemics and other widespread outbreaks of contagious disease, or natural disasters, including earthquakes, typhoons, hurricanes, floods, and fires; and business interruptions resulting from the COVID-19 pandemic or any other similar pandemic.
PHP-303 for the Treatment of AATD
Overview
For reasons discussed above, we had initially focused on AATD as the therapeutic area for PHP-303. PHP-303 is a novel, selective, oral, once-daily, small molecule that is designed to inhibit the bioactive form of NE. Scientific data indicated that the increased risk of lung tissue injury in AATD patients may be due to inadequately controlled NE caused by insufficient AAT. We hypothesized that by inhibiting NE, PHP-303 may have the potential to reduce the destruction of lung tissue and stabilize clinical (lung) deterioration in AATD patients.
Background of Alpha-1-Antitrypsin Deficiency: AATD is a rare genetic disease that results in quantitative and/or qualitative defects in the AAT protein (https://www.lung.org/lung-health-diseases/lung-disease-lookup/alpha-1-antitrypsin-deficiency). Individuals can be characterized by the genotype of the SERPINA1 gene. In general, single nucleotide polymorphisms give rise to gene variants resulting in AAT proteins with single amino acid alterations. Each SERPINA1 allele from each parent contributes 50 percent to the serum AAT protein level (autosomal codominant), and therefore the presence of a normal allele alleviates or mitigates the symptoms of the mutant SERPINA1 allele (autosomal recessive). Most severely affected AATD patients include individuals where both parents contributed (homozygous for) the Z allele (PI*ZZ), the null allele, or the F (PI*FF) allele. These individuals experience emphysema at young age of onset with risk dramatically increased by exposure to
36
cigarette smoke or occupational exposures. Patients with PI*ZZ genotype are also at a high risk of liver cirrhosis, due to abnormal intracellular protein folding of mutant AAT resulting in damage to liver cells. The F allele results in a functionally abnormal protein without anti-protease activity, although AAT levels are normal. Non-smoker heterozygotes (PI*MZ or PI*SZ genotypes) experience a lower risk of lung disease, though risk increases in smokers.
There are estimated to be 70,000 to 100,000 individuals with AATD in the US. Worldwide, more than 3 million people are at risk of severe deficiency of AAT (https://www.rarediseaseadvisor.com/disease-info-pages/alpha-1-antitrypsin-deficiency-epidemiology-aatd). Like smoking-related COPD, AATD patients present clinically with dyspnea, cough, sputum production and wheezing. Lung function testing reveals fixed airflow obstruction and reduced diffusing capacity. Two distinct features of AATD are younger age of onset and a particular pattern of emphysema on lung imaging. The presentation of emphysema in a non-smoker or an individual with a family history of liver disease is also suggestive. Laboratory diagnosis of AATD has also advanced: current approaches favor simultaneous testing of the serum AAT level and targeted genotyping for the most common variants. Prognosis of AATD patients is variable, with liver dysfunction accounting for mortality in most patients less than 40 years old. Longitudinal studies demonstrate progressive loss of lung function in older individuals, with annual rates of FEV1 decline of 44 -110 ml/year in non-smokers and much higher rates among smokers with AATD. Mortality rates increased dramatically as FEV1 fell below 35% predicted levels.
In addition to smoking abstinence or cessation, supportive treatments for AATD include those traditionally provided for COPD care such as nutritional support, pulmonary rehabilitation, prophylactic vaccines and supplemental oxygen. Guidelines support the administration of bronchodilators and corticosteroids. Replacement therapy for AAT is used for individuals with low serum levels of AAT and airflow obstruction. Pooled human AAT is administered by weekly infusion and is associated with adverse events and vein collapse necessitating a central line with long-term weekly intravenous infusions and include such products as Prolastin, Aralast, Zemaira, Trypsone, Alfalastin, Glassia, and Respreeza. These agents have been approved in the United States and Europe based on biochemical efficacy or demonstration of increased plasma levels of AAT. The 2015 RAPID trial demonstrated that replacement therapy reduced the rate of decline of lung density assessed by High- Resolution CT imaging, suggesting likely clinical benefit. This effect was sustained for a four-year treatment period (Chapman et al., 2015, Lancet 386:360). Lung transplantation is an option for selected subjects with advanced emphysema. Experimental therapies in development for AATD include NEI, (such as PHP-303), RNA interference agents, AAT correctors and gene therapy. None of these experimental approaches has yet demonstrated compelling clinical benefit nor gained regulatory approval.
Our Approach
Our product candidate for treating AATD is PHP-303, a selective and reversible NE inhibitor (NEI) with sub-nanomolar potency against the bioactive form of NE (von Nussbaum et al., 2015, Chem Med Chem 10:1163). Like other NEI, PHP-303 has the potential to reduce the enzymatic destruction of lung tissue in these patients. pH Pharma (now Peak Bio Co., Ltd.) have a relationship with and a research agreement with the Alpha-1 Project Foundation, a for-profit organization that advocates for treatments of AATD to enhance the lives of patients with this disease. We believe that patient advocacy groups such as Alpha-1 Project will assist in patient access, and unite clinicians, thought leaders and patients for our strategic partner’s future clinical trials. The convenient once-daily, oral dosing of PHP-303 could provide a significant advantage compared to the current treatments for AATD which are surgery and/or weekly intravenous AAT augmentation therapy.
Approved Phase 2 AATD Clinical Trial Design in Ireland/UK
pH Pharma, now Peak Bio Co., Ltd., has contracted a principal investigator at the Royal College of Surgeons in Ireland and a principal investigator at the University of Birmingham to conduct the Phase 2 AATD trial in Ireland and UK, each of whom have numerous publications and experience in the area of AATD clinical trials (For e.g., European Respiratory Journal 2019 53: 1900138; DOI: 10.1183/13993003.00138-2019). Data from this trial will inform the design of a pivotal trial with registrational intent.
Clinical Trial Applications are approved for a randomized, double-blinded placebo-controlled trial with AATD patients (PHP-303-A201 protocol). Primary endpoints include evaluation of safety for two PHP-303 dose levels over a 3-month once daily oral administration period. Secondary endpoints include pharmacodynamic readouts such as inhibition of NE activity in sputum and plasma, and surrogate biomarkers or predictors of efficacy such as evaluation of lung function, frequency and degree of disease progression, COPD assessment test, and St. George’s respiratory questionnaire.
As stated previously, Peak Bio is planning on partnering this program, the company is maintaining the above approved CTAs in both UK and Ireland for planned Phase 2 trials for the benefit of AATD patients. Any future/potential strategic partners may need to have additional conversations with above regulatory agencies in lieu of the accepted biomarkers by the US FDA and use the approved CTAs/ INDs as a platform to launch a Phase 2 clinical trial.

Material Agreements
The Bayer Agreement
In March 2017, the Company entered into an Assignment, License, Development and Commercialization Agreement with Bayer (the “Bayer Agreement”) in regard to the assignment by Bayer to the Company of Bayer’s patents covering the neutrophil elastase inhibitor compound BAY-85-8501 (referred throughout as PHP-303) and a license by Bayer to the Company of Bayer’s know-how for the development, manufacture and commercialization of the compound.
Under the Bayer Acquisition Agreement, the Company is committed to pay certain development and regulatory milestones up to an aggregate amount of $23,500,000 and high single digit royalties based on the sale of products developed based on the licensed compound. Royalties will be payable on a licensed product-by-licensed product and country-by-country basis until the later of ten years after the first commercial sale of such licensed product in such country and expiration of the last patent covering such licensed product in such country that would be sufficient to prevent generic entry.
The Bayer Agreement is terminable by either party for material breach by the other party or in the event of bankruptcy or insolvency of the other party, in each case, subject to an opportunity to cure of 90 and 60 days respectively. The Bayer Agreement is also terminable by the Company at any time for convenience or in the event of Company safety concerns.
Alpha-1 Project Research Agreement
On June 28, 2019, the Alpha-1 Project, Inc. (TAP) entered into a sponsored Research Agreement with pH Pharma Co, Ltd, (now referred to as Peak Bio Co., Ltd). TAP is a for-profit entity focused on identifying, funding, providing expertise and accelerating diagnostic and therapeutic interventions for patients with the rare disease AATD. Peak Bio Co., Ltd. has entered an agreement with TAP- $100,000 USD was provided by TAP towards research, and, Peak Bio Co., Ltd. issued TAP 4,800 shares of its common stock at the share price at that time. The funding is for the sole purpose of the clinical trial activities, investigating a potential role for PHP-303 in the treatment of AATD, where, Peak Bio Co., Ltd. is solely responsible for the management, conduct, oversight of the Research Plan and the generation of a final report/ results. TAP has the right to participate in any future external grant funding activities of Peak Bio Co., Ltd. and TAP may elect to participate in such funding on a “most favored nations” basis. Peak Bio and TAP formed a “steering committee” to oversee the funded activities during the term of the agreement and to act as a forum for TAP to provide reasonable comments and input on the scientific progress of the research.
TAP and Peak Bio Co., Ltd. have rights to publish data within the scope that does not compromise Peak Bio’s confidential information or proprietary know-how or trade secrets or that does not compromise securing patent protection of any inventions arising from the research plan. In addition, Peak Bio Co., Ltd. is required to acknowledge the support of TAP in any future publications from the research. Peak Bio Co., Ltd. will own all arising data and intellectual property arising from the research plan, and accordingly, TAP hereby assigned to Peak Bio Co., Ltd. (and shall cooperate with Peak Bio Co., Ltd. to execute assignment documents as necessary to perfect the assignment to Peak Bio Co., Ltd.) of any and all such intellectual property rights arising out of the research plan. TAP will acquire no ownership interest or other rights or licenses of any kind whatsoever in any intellectual property, data or results or any patents or patent applications or know-how arising out of the research plan.
TAP will be entitled to receive milestone payments as a percentage of total funding, with such payments due if, as and when the following events occur, during the development and commercialization of any product derived from the research plan. Milestone payments in aggregate will not exceed 350% of any money funded by TAP to Peak Bio for regulatory approval, achievement of first commercial sale and after cumulative net sales considerations. To date, the amount of the funded research proceeds provided to Peak Bio Co., Ltd. by TAP is $100,000 USD that would be subject to this payment calculation.
Department of Defense (DoD) grant for the evaluation of PHP-303 in Covid-19- related ARDS
In January 2021, we entered into an agreement with the U.S. DoD to perform “Preclinical Studies of PHP-303, a Neutrophil Elastase Inhibitor to Treat Severe COVID-19 Associated Acute Respiratory Distress Syndrome and Lung Injury”. We have been awarded up to $3,954,626 in expense reimbursement for preclinical studies to obtain pharmacokinetic data with PHP-303, and to determine if PHP-303 can inhibit NETosis and/or oppose the damaging effects of the large amounts of NE released into tissue during this biological process. And, if PHP-303 does inhibit NETosis, would this inhibition translate to improved outcomes in animal models of acute lung injury including a COVID-19 model.
We own all study data generated under the DoD Agreement, whether generated by us or the DoD, and the DoD will have no ownership interest in any inventions resulting from the agreement. Accordingly, any therapeutic or prototype developed under the agreement will be owned by Peak Bio. Under the DoD agreement, we are required to use commercially reasonable efforts to complete specified research activities for the prototype project based on the estimated cost for such prototype. In connection with
38
the DoD Agreement, we are eligible to receive up to $3,954,626 in the aggregate from DoD, subject to continued compliance with the terms of the DoD agreement and future pricing strategy. We are not obligated to pay any royalties or other future consideration under this agreement. The DoD agreement was extended to expire March 31, 2023, but has been temporarily placed on hold pending reprioritization of Peak’s pipeline and strategic objectives and hiring of staff. The DoD has the right to terminate the agreement in its entirety for convenience or in whole or in part for our material breach of the agreement.
The following statements are required to accompany any public release of information pertaining to the agreement:
Manufacturing
We have been using raw materials and finished products supplied directly from Bayer in Germany, which has the highest level of CMC (manufacturing/quality) technology among global pharmaceutical companies and have used them to supply our preclinical and initial clinical trials. For our finished products, we have transferred the technology to Catalent, the largest contract producer in the United States, for manufacture, allowing for the establishment of a very stable and efficient partnership for the supply of clinical investigational drugs and the development of commercial products.
PHP-303 Clinical Reagent Manufacturer |
Although PHP-303 is currently in early clinical development stage, we licensed the technology after Bayer had already achieved kilogram (kg) scale synthesis at high-purity, so late-stage clinical supply is possible with the current methods. The finished product has also been developed with a stable formulation, so PHP-303’s CMC process development has been completed from adding of high-capacity tablets to large-scale commercial production. |

We do not own or operate facilities for the manufacturing of our product candidates, nor do we have plans to develop our own manufacturing operations in the foreseeable future. We had entered into manufacturing agreements with a number of drug substance, drug product, and other manufacturers and suppliers for PHP-303, and we intended to enter into additional manufacturing agreements as necessary. Following our license of PHP-303, we acquired certain clinical trial materials from Bayer. Our manufacturing contacts, KOLs, SOPs, supplies of drug substances and drug products are available for any future partner should they choose to avail of this platform to accelerate their entry into phase 2 clinical trial. Future partners are free to continue with our manufacturers and suppliers, our CMC lots of PHP-303, or internalize and/or partner as they see fit with other contract manufacturers and generate new lots of PHP-303 for future trials. For this reason, we have not yet entered into any contractual relationships for the manufacture of commercial supplies of PHP-303 to offer strategic options for a future partner.
Commercialization, Sales, and Marketing
We do not have our own marketing, sales, or distribution capabilities.
Competition AATD
We compete directly with other biopharmaceutical and pharmaceutical companies that focus on the treatment of AATD or ARDS. We may also face competition from academic research institutions, governmental agencies, and other various public and private research institutions. We expect to face increasingly intense competition as new technologies become available. Any
39
product candidates, including PHP-303 that we successfully develop and commercialize will compete with existing therapies and new therapies that may become available in the future.
Currently, approved alpha1-proteinase inhibitors that are administered intravenously during AAT augmentation therapy may be considered PHP-303’s closest potential competitor in the treatment of AATD. Currently, there are four inhibitors on the market in the United States: Grifols’s Prolastin-C, Shire’s Aralast, CSL’s Zemaira and Kamada’s Glassia. Kamada is also investigating an inhaled version of augmentation therapy and Apic Bio and Adverum are in the early stages of developing gene-therapy approaches for AATD. Santhera has in-licensed an inhaled NEI and is planning a multiple ascending dose study, with the initial indication targeted being cystic fibrosis.
Another investigational NEI, Alvelestat (MPH-966) developed through a partnership of Mereo Biopharma with AstraZeneca, was investigated as a phase 2 clinical trial in patients with severe AATD-associated emphysema. The double-blind, placebo-controlled “ASTRAEUS” study evaluated two different doses of alvelestat (high or low [120mg] dose) administered twice daily, versus placebo, over a 12-week period. As mentioned previously, three primary biomarker endpoints linked to AATD-related lung disease progression were also evaluated in this trial. On May 9, 2022, Mereo announced positive top-line efficacy and safety results from this trial showing that at the high dose, alvelestat demonstrated statistically significant changes versus placebo in all three primary biomarker endpoints that included ~90% inhibition of NE at the high undisclosed dose (https://www.atsjournals.org/doi/abs/10.1164/ajrccm-conference.2023.207.1_MeetingAbstracts.A2844; https://www.atsjournals.org/doi/abs/10.1164/ajrccm-conference.2024.209.1_MeetingAbstracts.A1211). As biomarkers desmosine/ isodesmosine and Aa-Val360 levels were accepted as surrogate biomarkers reflecting disease severity of AATD patients in the phase 2 ASTRAEUS trial, this paves the regulatory path for future trials for NEIs. It is our belief these Mereo data support target and pathway engagement in AATD patients by a NEI at clinically available doses. To the extent these are class effects, these data also potentially de-risks the Peak Bio PHP-303 AATD program.
As discussed previously, PHP-303 has demonstrated greater than 90% NE inhibition at doses of 5mg, 10mg and 20mg as a once daily oral administration. Additionally, PHP-303 appears to inhibit the bioactive form of NE. This will be explored more in-depth as we progress the program forward.

The potential ADC product candidates in our pipeline such as Trop2 PH1 ADC are in the preclinical and IND-enabling stages of development, with only PHP-303 having progressed to clinical stages of development. Trop2 PH1 ADC has never been tested in human subjects. We may be unable to advance any current or future potential product candidates through the completion of clinical development, obtain regulatory approval and ultimately commercialize any of our product candidates, or experience significant delays in doing so.
45
46
47
Our Peak Bio R&D Toxin and ADC Platform Engine is evolving and may not reach a state at which building a pipeline of product candidates is possible.
48
We may expend our limited resources and access to capital to pursue a particular product candidate; these decisions may prove to be wrong and may adversely impact our business. Because we have limited financial and managerial resources, we intend to focus our efforts on specific R&D programs, such as our Trop2 PH1 ADC, our lead oncology ADC candidate, and eventually advancing additional research programs progressing from our Peak Bio R&D Discovery Toxin and ADC Platform Engine, seeking strategic partners for new ADC programs, while we seek a strategic partner for our clinical development product candidate(s) PHP-303.
The effects of health epidemics, geopolitical instability including what was encountered with the COVID-19 pandemic or the impact of any future pathogens of concern, the conflict in Eastern Europe and in regions where we, or the third parties on which we rely, have business operations could adversely impact our business, including our preclinical studies, anticipated clinical trials, and contract manufacturing capabilities. Similar or unrelated pandemics and/or the geopolitical instability in Eastern Europe could materially affect our operations, which have been affected by supply chain issues subject to foreign policy changes and/or executive orders, and at our future clinical trial sites, as well as the business or operations of our CROs, CDMOs, or other third parties with whom we conduct business and could be adversely impacted and cause significant disruptions and delays which could greatly impact our business and may continue to impact planned preclinical and clinical plans.
49
We or a future strategic partner depend on enrollment of patients in our clinical trials for our product candidates. If we or a future strategic partner are unable to enroll patients in our clinical trials, or enrollment is slower than anticipated, in particular for our product candidates with rare disease indications, research and development efforts could be adversely affected.
50
Our business is subject to risks associated with conducting business internationally. We source research and development, manufacturing, consulting, and other services from companies based throughout the United States, the EU, and select Asian countries.
If our future product candidates acquired or those derived or developed from our Peak Bio R&D Toxin and ADC Platform, continue in clinical trials, or are eventually initiated in clinical trials in human subjects, they may not demonstrate the combination of safety and efficacy necessary to become approvable or commercially viable.
Our product candidates are at an early stage of development, and we may not be able to successfully develop and commercialize them.
51
Our ability to commercialize our product candidates depends on first receiving Food and Drug Administration (FDA) approval.
52
We are currently operating in a period of economic uncertainty and capital markets disruption, which has been significantly impacted by geopolitical instability, an ongoing military conflict between Russia and Ukraine, and high inflation. Our business, financial condition and results of operations could be materially adversely affected by any negative impact on the global economy and capital markets resulting from the conflict in Ukraine, geopolitical tensions or high inflation.
U.S. and global markets are experiencing volatility and disruption following the escalation of geopolitical tensions and the start of the military conflict between Russia and Ukraine. On February 24, 2022, a full-scale military invasion of Ukraine by Russian troops was reported. Although the length and impact of the ongoing military conflict is highly unpredictable, the conflict in Ukraine could lead to market disruptions, including significant volatility in commodity prices, credit and capital markets, as well as supply chain interruptions, which has led to high inflation globally. We are continuing to monitor inflation, the situation in Ukraine and global capital markets and assessing the potential impacts on our business.
The global economy has been, and may continue to be, negatively impacted by Russia’s invasion of Ukraine. As a result of Russia's invasion of Ukraine, the U.S., the European Union, the United Kingdom, and other G7 countries, among other countries, have imposed substantial financial and economic sanctions on certain industry sectors and parties in Russia. Broad restrictions on exports to Russia have also been imposed. These measures include: (i) comprehensive financial sanctions against major Russian banks; (ii) additional designations of Russian individuals with significant business interests and government connections; (iii) designations of individuals and entities involved in Russian military activities; and (iv) enhanced export controls and trade sanctions limiting Russia's ability to import various goods. Russian military actions and the resulting sanctions could continue to adversely affect the global economy and financial markets and lead to instability and lack of liquidity in capital markets, potentially making it more difficult for us to obtain additional funds. Further, there are current geopolitical tensions with China. Recently, the Biden administration has signed multiple executive orders regarding China. One particular executive order titled Advancing Biotechnology and Biomanufacturing Innovation for a Sustainable, Safe, and Secure American Bioeconomy, signed on September 12, 2022, will likely impact the pharmaceutical industry to encourage U.S. domestic manufacturing of pharmaceutical products. Any additional executive orders or potential sanctions with China could materially impact our manufacturing partners.
In addition, on October 7, 2023, Hamas militants and members of other terrorist organizations infiltrated Israel’s southern border from the Gaza Strip and conducted a series of terror attacks on civilian and military targets. Thereafter, Hamas launched extensive rocket attacks on Israeli population and industrial centers located along the Israeli border with the Gaza Strip. Shortly following the attack, Israel’s security cabinet declared war against Hamas and launched an aerial bombardment of various targets within the Gaza Strip. The Israeli government subsequently called for the evacuation of over one million residents of the northern part of the Gaza Strip and initiated ground operations in the Gaza Strip. It is possible that other terrorist and/or regional organizations will join the hostilities as well, including Hezbollah in Lebanon, and Palestinian military organizations in the West Bank, resulting in a widening of the conflict. The intensity and duration of Israel’s current war against Hamas is difficult to predict as are such war’s economic implications on the global economy.
Although our business has not been materially impacted by these geopolitical tensions to date, it is impossible to predict the extent to which our operations, or those of our suppliers and manufacturers, will be impacted in the short and long term, or the ways in which the conflict may impact our business. The extent and duration of the conflict in Ukraine, geopolitical tensions, record inflation, sanctions and resulting market disruptions are impossible to predict, but could be substantial. Any such disruptions may also magnify the impact of other risks described herein.
Climate change or legal, regulatory or market measures to address climate change may negatively affect our business, results of operations, cash flows and prospects.
53
We believe that climate change has the potential to negatively affect our business and results of operations, cash flows and prospects. We are exposed to physical risks (such as extreme weather conditions or rising sea levels), risks in transitioning to a low-carbon economy (such as additional legal or regulatory requirements, changes in technology, market risk and reputational risk) and social and human effects (such as population dislocations and harm to health and well-being) associated with climate change. These risks can be either acute (short-term) or chronic (long-term).
The adverse impacts of climate change include increased frequency and severity of natural disasters and extreme weather events such as hurricanes, tornados, wildfires (exacerbated by drought), flooding, and extreme heat. Extreme weather and sea-level rise pose physical risks to our facilities as well as those of our suppliers. Such risks include losses incurred as a result of physical damage to facilities, loss or spoilage of inventory, and business interruption caused by such natural disasters and extreme weather events. Other potential physical impacts due to climate change include reduced access to high-quality water in certain regions and the loss of biodiversity, which could impact future product development. These risks could disrupt our operations and its supply chain, which may result in increased costs.
New legal or regulatory requirements may be enacted to prevent, mitigate, or adapt to the implications of a changing climate and its effects on the environment. These regulations, which may differ across jurisdictions, could result in us being subject to new or expanded carbon pricing or taxes, increased compliance costs, restrictions on greenhouse gas emissions, investment in new technologies, increased carbon disclosure and transparency, upgrade of facilities to meet new building codes, and the redesign of utility systems, which could increase our operating costs, including the cost of electricity and energy used by us. Our supply chain would likely be subject to these same transitional risks and would likely pass along any increased costs to us.
Environmental, social and governance matters may impact our business and reputation.
Governmental authorities, non-governmental organizations, customers, investors, external stakeholders and employees are increasingly sensitive to environmental, social and governance, or ESG, concerns, such as diversity and inclusion, climate change, water use, recyclability or recoverability of packaging, and plastic waste. This focus on ESG concerns may lead to new requirements that could result in increased costs associated with developing, manufacturing and distributing our products, when applicable. Our ability to compete could also be affected by changing customer preferences and requirements, such as growing demand for more environmentally friendly products, packaging or supplier practices, or by failure to meet such customer expectations or demand. While we strive to improve our ESG performance, we risk negative stockholder reaction, including from proxy advisory services, as well as damage to our brand and reputation, if we do not act responsibly, or if we are perceived to not be acting responsibly in key ESG areas, including equitable access to medicines and vaccines, product quality and safety, diversity and inclusion, environmental stewardship, support for local communities, corporate governance and transparency, and addressing human capital factors in our operations. If we do not meet the ESG expectations of our investors, customers and other stakeholders, we could experience reduced demand for our products, loss of customers, and other negative impacts on our business and results of operations.
Risks Relating to Development, Clinical Testing, Manufacturing and Regulatory Approval
Prior to our acquisition of PHP-303, we were not involved in its development and, as a result, we are dependent on Bayer having accurately reported the results and correctly collected and interpreted the data from all clinical trials conducted prior to our acquisition.
54
We, or a future strategic partner, face risks associated with the clinical development for PHP-303 and for our future ADC nominated candidates that are currently in preclinical development.
55
The success of our current product candidates will depend on many factors, including the following:
56
We or a future strategic partner may choose to, or may be required to, suspend, repeat, or terminate our clinical trials if they are not conducted in accordance with regulatory requirements, the results are negative or inconclusive or the trials are not well designed.
We are subject to environmental and other risks.
57
Risks Relating to Our Dependence on Third Parties
We rely, and expect to continue to rely, on third parties, including independent investigators and CROs, to conduct our clinical trials.
58
Manufacturing biotherapeutics, especially ADCs, is difficult and complex, and requires facilities specifically designed and validated for this purpose and we will use Contract Development Manufacturing Organizations (CDMOs) through various contract-manufacturing arrangements.
59
60
Because manufacturing processes and those of our contractors are highly complex and are subject to a lengthy FDA approval process, alternative qualified production capacity may not be available on a timely basis or at all. Difficulties or delays in our or our contractors’ manufacturing and supply of existing or new products could increase our costs, cause us to lose revenue or market share, damage our reputation and could result in a material adverse effect on our product sales, financial condition, and results of operations.
61
In some circumstances we may rely on current and future collaborators to assist in our R&D activities. If any of our partners do not satisfy their obligations under our agreements with them, or if they terminate our licenses, partnerships, or collaborations with them, we may not be able to develop or commercialize our licensed or partnered product candidates as planned.
62
Risks Relating to Intellectual Property
We rely on patents and other intellectual property rights to protect our product candidates, the obtainment, enforcement, defense, and maintenance of which may be challenging and costly. Failure to enforce or protect these rights adequately could harm our ability to compete and impair our business.
The issuance, scope, validity, enforceability, and commercial value of our and our current or future licensors’ patent rights are highly uncertain.
63
With respect to certain patents, we enjoy only limited geographical protection, and as a consequence we may not be able to protect our intellectual property rights throughout the world.
64
Our intellectual property rights may not adequately protect our technologies and product candidates and may not necessarily address all potential threats to our competitive advantage.
65
Our commercial success depends, in part, upon our ability to develop, manufacture, market, sell and partner our product candidates without alleged or actual infringement, misappropriation, or other violation of the patents and proprietary rights of third parties. Litigation relating to patents and other intellectual property rights in the biopharmaceutical and pharmaceutical industries is common, including patent infringement lawsuits and interferences, oppositions, and reexamination proceedings before the U.S. Patent and Trademark Office (the “USPTO”), and foreign patent offices.
66
67
We cannot guarantee that any of our, our licensors’, or the previous owners’ patent searches or analyses, including but not limited to the identification of relevant patents, the scope of patent claims, or the expiration of relevant patent applications or patents, are complete or thorough, nor can we be certain that we have identified each and every third-party patent and patent application in the United States, Europe and elsewhere that is relevant to or necessary for the commercialization of our product candidates in any jurisdiction.
Additionally, pending patent applications that have been published can, subject to certain limitations, be later amended in a manner that could cover our product candidates or the use of our product candidates.
68
If we or our licensors fail to maintain the patents and patent applications covering our product candidates or if we or our licensors otherwise allow our patents or patent applications to be abandoned or lapse, our competitors might be able to enter the market, which would hurt our competitive position and could impair our ability to successfully commercialize our product candidates in any indication for which they are approved.
69
We may be subject to claims challenging the inventorship of our patents and patent applications or ownership of our intellectual property.
70
Depending upon the timing, duration, and conditions of FDA marketing approval of our product candidates, one or more of our U.S. patents may be eligible for patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the “Hatch-Waxman Amendments.”
If our trademarks and trade names are not adequately protected, we may not be able to build name recognition in our markets of interest and our competitive position may be adversely affected.
71
We may be subject to claims by third parties asserting that we or our employees have misappropriated third-party intellectual property, or claiming ownership of what we regard as our own intellectual property. These claims may be costly to defend and if we do not successfully do so, we may be required to pay monetary damages and lose valuable intellectual property rights or personnel.
72
Risks Relating to Competitive Employment for Key Personnel and other Matters related to Managing Company Growth
73
We face intense competition and rapid technological change.
Our competitors may have superior products, manufacturing capability or marketing expertise.
74
We have no experience in commercializing products on our own.
Risks Relating to Commercialization
Market acceptance of our products is uncertain.
75
Our existing and future product candidates may not gain market acceptance, in which case our ability to generate product revenues will be compromised.
76
We expect to face competition.
77
78
We or a future strategic partner plan to seek orphan drug designation for PHP-303 and future rare disease product candidates.
79
We or any future strategic collaboration partners may seek and fail to obtain breakthrough therapy designation by the FDA for PHP-303 or any future product candidates or access to the PRIME scheme by the EMA for PHP-303 or any future product candidates.
80
We likely will commercialize or co-commercialize our product candidates for rare diseases and potentially rare tumor types and seek strategic relationships with third parties for the development and/or commercialization of our other product candidates.
81
Risks Relating to Healthcare Laws and Other Legal Compliance Matters
82
83
We face product liability risks and may not be able to obtain adequate insurance.
84
Our business operations and current and future relationships with investigators, healthcare professionals, consultants, third-party payors, patient organizations, and customers will be subject to applicable healthcare regulatory laws, which could expose us to penalties.
85
Our employees and independent contractors, including principal investigators, CROs, CMOs, consultants, vendors, and any other third parties we may engage in connection with the development and commercialization of our product candidates may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements, which could adversely affect our business.
86
We are subject to governmental regulation and other legal obligations related to privacy, data protection and data security. Our actual or perceived failure to comply with such obligations could harm our business.
87
We are also subject to evolving European privacy laws on electronic marketing and cookies.
Although the clinical trial process is designed to identify and assess potential side effects, it is always possible that a drug, even after regulatory approval, may exhibit unforeseen side effects. If our product candidates were to cause adverse side effects during clinical trials or after approval, we may be exposed to substantial liabilities.
88
We may be exposed to future liabilities and/or obligations with respect to sales or out-licensing arrangements or partnerships.
Additional Risks Relating to Ownership of Company Securities
Nasdaq has delisted our securities from trading on its exchange, which could limit investors’ ability to make transactions in our securities and subject us to additional trading restrictions.
Currently, our Common Stock is publicly traded on the OTC Markets Pink tier. No assurance can be given that our securities will trade on a national securities exchange, such as the Nasdaq Stock Market LLC (the “Nasdaq”) or the New York Stock Exchange (the “NYSE”), or the OTC Markets’ OTCQB or OTCQX tiers in the future or that the trading prices of our Common Stock on the OTC Markets will be indicative of the prices of our Common Stock if our Common Stock were traded on a national securities exchange. As previously disclosed, on November 1, 2022, we received written notice from the Staff of the Listing Qualifications Department of Nasdaq (the “Staff”) stating that the Staff has determined that the Company has not complied with the requirements of IM-5101-2 because (i) the Company has not demonstrated that its common stock complies with the minimum 1,000,000 unrestricted publicly held shares requirement in Listing Rule 5505(a)(2) (the “Unrestricted Publicly Held Shares Requirement”) and (ii) the Company’s public warrants (the “Public Warrants”) do not qualify for initial listing since the security underlying the warrants, the Company’s Common Stock, does not qualify. The Company timely requested a hearing before the Nasdaq Hearings Panel (the “Panel”) and such hearing has been conducted, which ultimately stayed the suspension of the Company’s Common Stock and Public Warrants and the filing by Nasdaq of a Form 25-NSE (the “Form 25”), pending the Panel’s decision. On January 6, 2023, the Company received a determination letter (the “Determination Letter”) from the Panel to delist the Company’s Common Stock and Public Warrants from Nasdaq. The Determination Letter indicated Nasdaq will suspend trading in the Company’s Common Stock and Public Warrants effective at the open of business on January 10, 2023 and indicated that it intends to file a Form 25-NSE Notification of Delisting with the SEC once all applicable appeal and review periods have expired in order to effect the formal delisting of the Company’s securities from Nasdaq. The Determination Letter provided that the Company may request an appeal of the Panel’s decision to the Nasdaq Listing and Hearing Review Council within 15 days of the date of the Determination Letter. Since the Company did not request an appeal, the Form 25 was filed
89
thereafter by Nasdaq. Upon suspension from Nasdaq, the Company’s Common Stock began to trade on the OTC Markets “Pink” tier. As of the date of this Annual Report on Form 10-K, the Company's Common Stock is listed on the OTC Grey Market.
As a result of the delisting of our securities by Nasdaq, we may face significant material adverse consequences until we are able to list our securities on another national securities exchange, including:
The National Securities Markets Improvement Act of 1996, which is a federal statute, prevents or preempts the states from regulating the sale of certain securities, which are referred to as “covered securities.” Since our Common Stock and warrants are no longer currently listed on the Nasdaq, they are not deemed “covered securities.” Therefore, we may be subject to regulation in each state in which we offer our securities, which could materially adversely affect our business, financial condition and results of operations.
Our stock may be traded infrequently and in low volumes, so you may be unable to sell your shares at or near the quoted bid prices if you need to sell your shares.
Until our Common Stock is listed on a national securities exchange, our Common Stock may only trade on one of the OTC Markets (if we are successful in applying to trade on such marketplaces) or on the OTC Grey Market. In those markets, however, the shares of our Common Stock may trade infrequently and in low volumes, meaning that the number of persons interested in purchasing our Common Stock at or near bid prices at any given time may be relatively small or non-existent. An investor may find it difficult to obtain accurate quotations as to the market value of our common stock or to sell his or her shares at or near bid prices or at all. In addition, if we fail to meet the criteria set forth in SEC reporting regulations, various requirements would be imposed by law on broker-dealers who sell our securities to persons other than established customers and accredited investors. Consequently, such regulations may deter broker-dealers from recommending or selling our common stock, which may further affect the liquidity of our common stock. This would also make it more difficult for us to raise capital.
There currently is no active public market for our Common Stock and there can be no assurance that an active public market will ever develop. Failure to develop or maintain a trading market could negatively affect the value of our Common Stock and make it difficult or impossible for you to sell your shares.
There is currently no active public market for shares of our Common Stock, and one may never develop. Our Common Stock is currently traded on the OTC Grey Market. The OTC Grey Market is a thinly traded market and lacks the liquidity of certain other public markets with which some investors may have more experience. We may not ever be able to satisfy the requirements to be quoted on the OTC Markets or satisfy the listing requirements to be listed on a national securities exchange, which are often more widely traded and liquid markets. Some, but not all, of the factors which may delay or prevent the quotation or listing of our common stock on a more widely-traded and liquid market include the following: our stockholders’ equity may be insufficient; the market value of our outstanding securities may be too low; our net income from operations may be too low; our Common Stock may not be sufficiently widely held; we may not be able to secure market makers for our Common Stock; and we may fail to meet the rules and requirements mandated by the several exchanges and markets to have our Common Stock listed. Should we fail to satisfy the initial listing standards of the national exchanges or OTC Markets, or our Common Stock is otherwise rejected for listing or quotation, and remains traded on the OTC Grey Market, the trading price of our Common Stock could suffer and the trading market for our Common Stock may be less liquid, and our Common Stock price may be subject to increased volatility, making it difficult or impossible to sell shares of our Common Stock.
We cannot assure you that an active public market for our Common Stock will develop or be sustained. The market price of our Common Stock could be subject to wide fluctuations in response to many risk factors listed in this section, and others beyond our control, including:
90
91
Our existing stockholders have significant control of our management and affairs, which they could exercise against your best interests.
Risks Relating to future indebtedness if debt financing is needed
92
To service any of our future indebtedness, we will require a significant amount of cash. Our ability to generate cash depends on many factors beyond our control.
Fluctuations in our operating results could affect the price of our common stock. Our operating results may vary from period to period for several reasons including:
We incur increased costs and obligations as a result of being a public company.
93
Because there are no current plans to pay cash dividends on our Common Stock for the foreseeable future, you may not receive any return on investment unless you sell your common stock for a price greater than that which you paid for it.
We intend to retain future earnings, if any, for future operations, expansion and debt repayment and there are no current plans to pay any cash dividends for the foreseeable future. The declaration, amount and payment of any future dividends on shares of our Common Stock will be at the sole discretion of our board of directors. Our board of directors may take into account general and economic conditions, our financial condition and results of operations, our available cash and current and anticipated cash needs, capital requirements, contractual, legal, tax, and regulatory restrictions, implications on the payment of dividends by us to our stockholders or by its subsidiaries to it and such other factors as our board of directors may deem relevant. In addition, our ability to pay dividends is limited by covenants of our existing and outstanding indebtedness and may be limited by covenants of any future indebtedness that we incur. As a result, you may not receive any return on an investment in our Common Stock unless you sell our Common Stock for a price greater than that which you paid for it.
If securities analysts do not publish research or reports about our business or if they downgrade our stock or our sector, our stock price and trading volume could decline.
The trading market for our Common Stock will rely in part on the research and reports that industry or financial analysts publish about us or our business. We will not control these analysts. In addition, some financial analysts may have limited expertise with our model and operations. Furthermore, if one or more of the analysts who do cover the downgrade of our stock or industry, or the stock of any of our competitors, or publish inaccurate or unfavorable research about our business, the price of our stock could decline. If one or more of these analysts ceases coverage of us or fails to publish reports on it regularly, we could lose visibility in the market, which in turn could cause its stock price or trading volume to decline.
Future sales, or the perception of future sales, by us or our stockholders in the public market could cause the market price for our Common Stock to decline.
The sale of shares of our Common Stock in the public market, or the perception that such sales could occur, could harm the prevailing market price of shares of our Common Stock. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that it deems appropriate.
In addition, Common Stock reserved for future issuance under our equity incentive plans will become eligible for sale in the public market once those shares are issued, subject to provisions relating to various vesting agreements, lock-up agreements and, in some cases, limitations on volume and manner of sale applicable to affiliates under Rule 144, as applicable. The aggregate number of shares of our Common Stock reserved for future issuance under our equity incentive plan is 3,756,816. We will file one or more registration statements on Form S-8 under the Securities Act of 1933, as amended (the “Securities Act”) to register shares of Common Stock or securities convertible into or exchangeable for shares of Common Stock issued pursuant to our equity incentive plans. Any such Form S-8 registration statements will automatically become effective upon filing. Accordingly, shares registered under such registration statements will be available for sale in the open market.
Depending upon market liquidity at the time, sales of shares of our Common Stock under the White Lion Purchase Agreement may cause the trading price of our Common Stock to decline. After White Lion has acquired shares under the White Lion Purchase Agreement, it may sell all, some or none of those shares. Sales to White Lion by us pursuant to the White Lion Purchase Agreement may result in substantial dilution to the interests of other holders of our Common Stock. The sale of a substantial number of shares of our Common Stock to White Lion, or anticipation of such sales, could make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise wish to effect sales.
94
However, we have the right to control the timing and amount of any sales of our shares to White Lion, and the White Lion Purchase Agreement may be terminated by us at any time at our discretion without penalty.
The sale of substantial amounts of shares of our Common Stock or warrants, or the perception that such sales could occur, could cause the prevailing market price of shares of our Common Stock to decline significantly. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate. We believe the likelihood that warrant holders will exercise their Warrants is dependent upon the market price of our Common Stock.
In the future, we may also issue its securities in connection with investments or acquisitions. The amount of shares of Common Stock issued in connection with an investment or acquisition could constitute a material portion of our then-outstanding shares of Common Stock. Any issuance of additional securities in connection with investments or acquisitions may result in additional dilution to our stockholders.
Warrants will become exercisable for our Common Stock, which would increase the number of shares eligible for future resale in the public market and result in dilution to our existing stockholders.
Each Public and Private Placement Warrant, initially issued by Ignyte Sponsor LLC, entitles the holder thereof to purchase one (1) share of our Common Stock at a price of $11.50 and $0.60 per share for the Convertible Note Warrants (as defined below), subject to adjustment. Warrants may be exercised only for a whole number of shares of Common Stock. To the extent such warrants are exercised, additional shares of our Common Stock will be issued, which will result in dilution to the then existing holders of our Common Stock and increase the number of shares eligible for resale in the public market. Sales of substantial numbers of such shares in the public market could adversely affect the market price of our Common Stock.
Convertible notes may be converted for our Common Stock, which would increase the number of shares eligible for future resale in the public market and result in dilution to our existing stockholders.
Each April 2023 Convertible Note (as defined below) entitles the holder thereof to convert each dollar of outstanding principal and accrued interest into one (1) share of our Common Stock at a price of $0.60 per share, subject to adjustment.
Each December 2023 Convertible Note and May 2024 Convertible Note (as defined below) automatically converts each dollar of outstanding principal and accrued interest into one (1) share of our Common Stock at a per share price equal to the 30 day volume weighted average price of the surviving company multiplied by a discount rate of 70% and 50%, respectively. This automatic conversion is contingent on closing of a Business Combination (as detailed below). The December 2023 Notes entitles the holder thereof to convert each dollar of outstanding principal and accrued interest into one (1) share of our Common Stock at a per share price equal to the 30 day volume weighted average price of the Company multiplied by a discount rate of 90%. This optional conversion is contingent on the Company maintaining a listing on a Public Exchange.
Convertible Notes may be converted only for a whole number of shares of Common Stock. To the extent such notes are converted, additional shares of our Common Stock will be issued, which will result in dilution to the then existing holders of our Common Stock and increase the number of shares eligible for resale in the public market. Sales of substantial numbers of such shares in the public market could adversely affect the market price of our Common Stock.
Our management and auditors have expressed substantial doubt about our ability to continue as a going concern.
Our auditors’ report to our December 31, 2023 financial statements includes an explanatory paragraph that expressed substantial doubt about our ability to continue as a going concern. Our current cash level raises substantial doubt about our ability to continue as a going concern without immediate short-term financing required to get us through consummation of the Business Combination. Additionally, our management has independently determined that there is substantial doubt about Peak Bio’s ability to continue as a going concern because our cash flows generated from operations may not be sufficient to meet our current operating costs. In addition, our future financial statements may include similar qualifications about our ability to continue as a going concern. Peak Bio’s financial statements were prepared assuming that it will continue as a going concern and do not include any adjustments that may result from the outcome of this uncertainty. If Peak Bio is unable to meet its current operating costs, Peak Bio would need to seek or additional financing or modify or cease its operational plans. If Peak Bio seeks additional financing to fund its business activities in the future and there remains substantial doubt about its ability to continue as a going concern, investors or other financing sources may be unwilling to provide additional funding to Peak Bio on commercially reasonable terms or at all.
95
The JOBS Act permits “emerging growth companies” like us to take advantage of certain exemptions from various reporting requirements applicable to other public companies that are not emerging growth companies.
We qualify as an “emerging growth company” as defined in Section 2(a)(19) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012, which we refer to as the “JOBS Act.” As such, we will take advantage of certain exemptions from various reporting requirements applicable to other public companies that are not emerging growth companies for as long as it continues to be an emerging growth company, including (i) the exemption from the auditor attestation requirements with respect to internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act, (ii) the exemptions from say-on-pay, say-on-frequency and say-on-golden parachute voting requirements and (iii) reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements. As a result, our stockholders may not have access to certain information they deem important. We will remain an emerging growth company until the earliest of (i) the last day of the fiscal year (a) following February 1, 2026, the fifth anniversary of the closing of Ignyte’s IPO, (b) in which we have total annual gross revenue of at least $1.235 billion or (c) in which we are deemed to be a large accelerated filer, which means the market value of our Common Stock that are held by non-affiliates exceeds $700 million as of the last business day of our prior second fiscal quarter, and (ii) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period.
In addition, Section 107 of the JOBS Act also provides that an emerging growth company can take advantage of the exemption from complying with new or revised accounting standards provided in Section 7(a)(2)(B) of the Securities Act as long as Porch is an emerging growth company. An emerging growth company can therefore delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies, but any such election to opt out is irrevocable. We have elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, we, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of our financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.
We cannot predict if investors will find our Common Stock less attractive because we will rely on these exemptions. If some investors find our Common Stock less attractive as a result, there may be a less active trading market for Common Stock and our stock price may be more volatile.
Anti-takeover provisions in our organizational documents could delay or prevent a change of control.
Certain provisions of our Amended and Restated Charter and Amended and Restated Bylaws have an anti-takeover effect and may delay, defer or prevent a merger, acquisition, tender offer, takeover attempt or other change of control transaction that a stockholder might consider in its best interest, including those attempts that might result in a premium over the market price for the shares held by our stockholders.
These provisions provide for, among other things:
These anti-takeover provisions could make it more difficult for a third party to acquire us, even if the third party’s offer may be considered beneficial by many of our stockholders. As a result, our stockholders may be limited in their ability to obtain a premium for their shares. These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect directors of your choosing and to cause us to take other corporate actions you desire. See “Description of Securities.”

Our Amended and Restated Charter designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or stockholders.
Our Amended and Restated Charter provides that, subject to limited exceptions, any (1) derivative action or proceeding brought on behalf of us, (2) action asserting a claim of breach of a fiduciary duty owed by any director, officer, stockholder or employee to us or our stockholders, (3) action asserting a claim arising pursuant to any provision of the DGCL or our Amended and Restated Charter or our Amended and Restated Bylaws, or (4) action asserting a claim governed by the internal affairs doctrine shall, to the fullest extent permitted by law, be exclusively brought in the Court of Chancery of the State of Delaware or, if such court does not have subject matter jurisdiction thereof, another state or federal court located within the State of Delaware. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock shall be deemed to have notice of and to have consented to the provisions of our Amended and Restated Charter described above. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or its directors, officers or other employees, which may discourage such lawsuits against us and our directors, officers and employees. Alternatively, if a court were to find these provisions of our Amended and Restated Charter inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business and financial condition.
We have identified a material weakness in our internal control over financial reporting which could, if not remediated, result in material misstatements in our financial statements.
Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). Our internal control system was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes, in accordance with generally accepted accounting principles in the United States. Due to inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness of the internal control over financial reporting to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies and procedures may deteriorate.
Our management, under the supervision and with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our internal control over financial reporting as of the end of the period covered by this Annual Report on Form 10-K. As a result of this evaluation, management identified control deficiencies that constituted a material weakness in our internal control over financial reporting. The Company’s internal control over financial reporting is ineffective with respect to its financial closing process with respect to (i) preparation, review and approval of journal entries including the reasonableness of critical accounting estimates, (ii) timely closings as required to maintain compliance with reporting deadlines under applicable Securities and Exchange Commission regulations, (iii) evaluation of third party financial reporting advisors’ capabilities and the monitoring and evaluation of the accuracy and completeness of their work product, and (iv) accuracy of diluted earnings per share calculation. The Company experienced difficulties in applying complex accounting principles including (i) financial instruments accounted for under ASC 480 and ASC 815-10, (ii) differentiating between contractual liabilities and gain and loss contingencies, and (iii) fair value measurements.
Management continues to work to improve its controls related to our material weaknesses, specifically implementing improved processes and internal controls to ensure the proper application of accounting practices and guidance. We also intend to increase our accounting staff as soon as economically feasible and sustainable to remediate these material weaknesses. These material weaknesses will not be considered to be remediated until the applicable remediated controls are operating for a sufficient period of time and management has concluded that these controls are operating effectively. Until remediated, these material weaknesses could result in future errors to our financial statements. However, we can give no assurance that the measures we take will remediate the material weakness or that additional material weaknesses will not arise in the future. Any failure to remediate the material weakness, or the development of new material weaknesses in our internal control over financial reporting, could result in material misstatements in our financial statements and cause us to fail to meet our reporting and financial obligations, which in turn could have a negative impact on our financial condition.

Item 1B. Unresolved Staff Comments.
None.
Item 1C. Cybersecurity
The identification, detection, prevention and remediation of known or potential IT security vulnerabilities, including those arising from third-party hackers, hardware or software, is extremely costly and time consuming. We do not have the manpower, expertise or financial resources to effectively identify, detect, prevent or remediate cybersecurity risks. No assurance or guarantee whatsoever can be given that we will not be seriously damaged by the exploitation of our cybersecurity vulnerabilities.
During the year ended December 31, 2023, we did not identify any cybersecurity threats that have materially affected or are reasonably likely to materially affect our business strategy, results of operations, or financial condition. However, we may not be aware of all vulnerabilities or might not accurately assess the risks of incidents, and such preventative measures cannot provide absolute security and may not be sufficient in all circumstances or mitigate all potential risks.
Item 2. Properties.
Our principal executive office is located in Pleasanton, California, which consists of general office space. We are in the process of seeking laboratory facilities to replace the previous facility in Palo Alto, California. We believe that our existing facilities are adequate to meet our needs and that existing needs and future growth can be accommodated by leasing alternative or additional space.
Item 3. Legal Proceedings.
The Company is not currently a party to any material legal proceedings. At each reporting date, the Company evaluates whether a potential loss amount or a potential range of loss is probable and reasonably estimable under the provisions of the authoritative guidance that addresses accounting for contingencies. The Company expenses the costs related to its legal proceedings as incurred.
Item 4. Mine Safety Disclosures.

You should read the following discussion and analysis of Peak Bio’s financial condition and results of operations together with Peak Bio’s audited consolidated financial statements and notes thereto included elsewhere in this Annual Report on Form 10-K. Certain of the information contained in this discussion and analysis or set forth elsewhere in this Annual Report on Form 10-K, including information with respect to plans and strategy for Peak Bio’s business, includes forward-looking statements that involve risks and uncertainties. As a result of many factors, including those factors set forth in the section entitled “Risk Factors,” Peak Bio’s actual results could differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis. You should carefully read the section entitled “Risk Factors” to gain an understanding of the important factors that could cause actual results to differ materially from Peak Bio’s forward-looking statements. Please also see the section entitled “Cautionary Note Regarding Forward-Looking Statements.”
Unless otherwise indicated or the context otherwise requires, references in this Peak Bio’s Management’s Discussion and Analysis of Financial Condition and Results of Operations section to “Peak Bio,” “we,” “us,” “our” and other similar terms refer to Peak Bio Co., Ltd. prior to the Business Combination and to Peak Bio, Inc. and its consolidated subsidiaries after giving effect to the Business Combination.
Overview
Peak Bio is a clinical-stage biopharmaceutical company focused on developing therapeutics addressing significant unmet need in the areas of oncology, inflammation and rare diseases. Our management team has a combined 50 years of industry experience in the areas of small molecules, antibodies, and antibody-drug-conjugates (ADC).
With our current strategic focus, we have leveraged two decades of industry learning in the antibody-drug-conjugate (ADC) field to develop a platform of proprietary technologies that enable us to design ADCs to have improved efficacy, safety, and tolerability relative to existing antibody or ADC therapies. Our most advanced platform, PH-1 or Thailanstatin is being used to generate a pipeline of proprietary ADC product candidates to address patient populations with improved efficacy relative to traditional ADC-based therapies. Our second product candidate is an ADC targeting Trop2, an antigen broadly expressed in solid tumors. We expect our Trop2 ADC to enter clinical development by late 2024. Our Trop2 ADC and other undisclosed discovery-stage product candidates are based on our proprietary PH-1 platform of toxin payloads targeting RNA splicing.
Despite commercial success of the ADCs currently on the market, there continues to be a need for ADCs that not only deliver antibody-directed payloads selectively to their tumors, but to also release them safely via improved linker technology and avoid off- target toxicities. Secondly, we believe that adding an immunomodulatory effect to our toxin(s) that engages our immune systems to assist in the cancer killing would contribute to improved tumor killing.
Our lead product candidate for which we are seeking a strategic partner for, PHP-303 is a small molecule, 5th generation Phase 2 clinical-ready neutrophil elastase (NE) inhibitor (NEI). We are planning a Phase 2 clinical study in Alpha-1 anti-trypsin deficiency (AATD) patients. We have completed two Phase 1 trials of PHP-303 in healthy volunteers testing higher doses of PHP-303 by single-ascending dose (SAD) and multiple-ascending dose (MAD). PHP-303 demonstrated dose- dependent pharmacokinetics and the recommended Phase 2 dose was achieved in these trials. A maximum tolerated dose for PHP-303 was not achieved in these Phase 1 trials.
We do not have any products available for commercial sale, and we have not generated any product revenue from our portfolio of product candidates or other sources. Our ability to generate revenue sufficient to achieve profitability, if ever, will depend on the successful development and eventual commercialization of our potential therapies, which we expect, if it ever occurs, will take a number of years. The research and development efforts require significant amounts of additional capital and adequate personnel infrastructure. There can be no assurance that our research and development activities will be successfully completed, or that our potential therapies will be commercially viable.
We have incurred significant losses since the commencement of our operations. Our net loss was $12.8 million and $13.1 million for the years ended December 31, 2023 and 2022, respectively. Since the beginning of 2024, we raised aggregate gross proceeds of approximately $0.7 million from the issuance of December 2023 Convertible Notes, $0.75 million from the issuance of secured Founder promissory notes, and $3.5 million from the issuance of May 2024 Convertible Notes. We expect to incur significant expenses and operating losses for the foreseeable future as we continue our efforts to identify product candidates and seek regulatory approvals within our portfolio.
We will need additional financing to fund our ongoing activities and to close the Merger with Akari (defined below). We may raise this additional funding through the sale of equity, debt financings or other capital sources, including potential collaborations with other companies or other strategic transactions and funding under government contracts.
On November 1, 2022, we received written notice (the “Notice”) from the Staff of the Listing Qualifications Department (the “Staff”) of the Nasdaq Stock Market LLC (“Nasdaq”) stating that the Staff determined that we had not complied with the
100
listing requirements because (i) we had not demonstrated that our common stock complied with the minimum 1,000,000 unrestricted publicly held shares requirement. We requested, and received, a hearing with the Hearings Panel (the “Panel”) on December 8, 2022 to appeal Nasdaq’s determination, which request stayed the suspension of our common stock and warrants and the filing by Nasdaq of a Form 25-NSE pending the Panel’s decision.
On January 6, 2023, we received the determination letter (the “Determination Letter”) from the Panel to delist our common stock and warrants from Nasdaq. Nasdaq suspended trading in our common stock and warrants effective at the open of business on January 10, 2023. Upon suspension from Nasdaq, our securities began trading on the OTC Markets’ “OTC Pink Market” tier.
We may be unable to raise additional funds or enter into other arrangements when needed on favorable terms, or at all. There can be no assurances that other sources of financing will be available. Due to these uncertainties, there is substantial doubt about our ability to continue as a going concern.
The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. The consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or classification of liabilities that might result from the outcome of the uncertainties discussed above.
Recent Developments
Akari Merger
Merger Agreement
On March 4, 2024, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Akari Therapeutics, Plc, a public company limited by shares incorporated in England and Wales (“Akari”), and Pegasus Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Akari (“Merger Sub”), pursuant to which, upon the terms and subject to the conditions thereof, Merger Sub will be merged with and into Peak Bio (the “Merger”), with Peak Bio surviving the Merger as a wholly-owned subsidiary of Akari.
Pursuant to the Merger Agreement, and upon the terms and subject to the conditions thereof, at the effective time of the Merger (the “Effective Time”), each issued and outstanding share of Common Stock (other than (x) shares of Common Stock held by us as treasury stock, or shares of Common Stock owned by Akari, Merger Sub or any direct or indirect wholly-owned subsidiaries of Akari and (y) Dissenting Shares (as defined in the Merger Agreement)), will be converted into the right to receive Akari American Depositary Shares (“Akari ADSs”) representing a number of Akari ordinary shares, par value $0.0001 per share (the “Akari Ordinary Shares”), equal to an exchange ratio calculated in accordance with the Merger Agreement (the “Exchange Ratio”), each such share duly and validly issued against the deposit of the requisite number of Akari Ordinary Shares in accordance with the Deposit Agreement (as defined in the Merger Agreement). The Exchange Ratio will be calculated such that the total number of shares of Akari ADSs to be issued as merger consideration for the Peak Common Stock will be expected to be, upon issuance, approximately 50% of the outstanding shares of Akari ADSs (provided, certain adjustments to this ratio will be made in respect of the net cash, as determined in accordance with the Merger Agreement, of each of Peak Bio and Akari at the close of business one business day prior to the anticipated consummation of the Merger). The Merger Agreement provides that, under certain circumstances, additional Akari ADSs may be issued to the holders of shares of Peak Common Stock following the consummation of the Merger equal to an exchange ratio calculated in accordance with the Merger Agreement (the “Additional Exchange Ratio”).
At the Effective Time, each warrant to purchase capital stock of Peak Bio (“Peak Warrant”) outstanding immediately prior to the Effective Time will be converted into and exchangeable for warrants to purchase a number of Akari Ordinary Shares or Akari ADSs, as determined by Akari (each, an “Adjusted Warrant”), on substantially similar terms and subject to substantially similar conditions as were applicable to such Peak Warrant immediately prior to the Effective Time, except (i) for terms rendered inoperative by reason of the transactions contemplated by the Merger Agreement, (ii) as provided in the following sentence and (iii) such amendments to the terms of the Adjusted Warrants as are necessary to comply with applicable Law (as defined in the Merger Agreement). The number of Akari Ordinary Shares (or the number of Akari Ordinary Shares underlying Akari ADSs, as applicable) subject to each Adjusted Warrant will be equal to the number of shares of Peak Common Stock issuable upon exercise of such Peak Warrant immediately prior to the Effective Time multiplied by the Exchange Ratio, with any fractional Akari Ordinary Shares or Akari ADSs rounded down to the nearest whole Akari Ordinary Share or Akari ADS, as applicable, and the exercise price with respect to each Akari Ordinary Share (or each Akari Ordinary Share underlying Akari ADSs, as applicable) underlying such Adjusted Warrant will be equal to the exercise price of such Peak Warrant immediately prior to the Effective Time divided by the Exchange Ratio. The grant of the Adjusted Warrants will be effected as of the Effective Time, or as soon
101
thereafter as is reasonably practicable, taking into account Parent’s administrative procedures. The Adjusted Warrants will be further adjusted, if applicable, to give effect to the impact of the Additional Exchange Ratio.
Each option to acquire shares of Peak Common Stock (“Peak Option”) that is outstanding and unexercised immediately prior to the Effective Time, whether or not vested, will be assumed and converted into an option to purchase a number of Akari ordinary shares or Akari ADSs, as determined by Akari (each, an “Adjusted Option”). The number of Akari Ordinary Shares (or the number of Akari Ordinary Shares underlying Akari ADSs, as applicable) subject to the Adjusted Option will be equal to the product of (i) the total number of shares of Peak Common Stock subject to such Peak Option immediately prior to the Effective Time multiplied by (ii) the Exchange Ratio, with any fractional Akari Ordinary Shares or Akari ADSs rounded down to the nearest whole Akari Ordinary Share or Akari ADS, as applicable, and the exercise price per share of each Adjusted Option will be equal to the exercise price of such Peak Option immediately prior to the Effective Time divided by the Exchange Ratio. The Adjusted Options will be further adjusted, if applicable, to give effect to the impact of the Additional Exchange Ratio.
Voting Agreements
Concurrently with the Merger Agreement, we and Akari entered into voting and support agreements (the “Voting Agreements”) with certain stockholders of Peak Bio (the “Peak Stockholders”) and certain shareholders of Akari (the “Akari Shareholders” and, together with the Peak Stockholders, the “Supporting Holders”). The Supporting Holders have agreed to, among other things, vote their shares in favor of the Merger Agreement and the Merger or the issuance of Akari Ordinary Shares in connection therewith, as applicable, in accordance with the recommendation of the respective boards of directors of Peak Bio and Akari.
Bylaws Amendment
In connection with the execution of the Merger Agreement, on March 3, 2024, our Board approved an amendment to our Amended and Restated Bylaws (the “Bylaws Amendment”), which became effective immediately. The Bylaws Amendment requires that, unless we consent in writing to the selection of an alternative forum, the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the Company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer, employee or stockholder (including a beneficial owner) of the Company to the Company or the Company’s stockholders, (iii) any action asserting a claim against any director, officer, employee or stockholder (including a beneficial owner) of the Company arising under any provision of the Delaware General Corporation Law (“DGCL”) or the bylaws or the certificate of incorporation of the Company, or (iv) any action asserting a claim governed by the internal affairs doctrine shall, to the fullest extent permitted by law, be the Court of Chancery of the State of Delaware (or if the Court of Chancery for the State of Delaware does not have jurisdiction, a state court located within the State of Delaware or, if no state court located within the State of Delaware has subject matter jurisdiction, the federal district court for the District of Delaware). In addition, the Bylaws Amendment provides that unless the Company consents in writing to the selection of an alternative forum, the federal district courts of the United States shall be the exclusive forum for the resolution of any claim or cause of action arising under the Securities Act of 1933, as amended.

Convertible Notes
2022 Convertible Note
On November 1, 2022, we issued a $1,512,500 convertible note to EarlyBirdCapital, Inc., the sole book running manager of Ignyte’s IPO, in lieu of the deferred underwriting fee that was payable at the Closing. The convertible note accrued interest at a rate of 8% per annum and was payable on October 31, 2023, provided however that we agree to make mandatory prepayments on this note (which shall first be applied to accrued interest and then to principal) from time to time in amounts equal to 15% of the gross proceeds received by us from any equity lines, forward purchase agreements or other equity financings consummated by us prior to the maturity date.
On the maturity date, the note holder had the right, in its sole and absolute discretion, to convert all or part of the principal and/or accrued interest of this convertible note into shares of our common stock of at a per share conversion price equal to 90% of the volume weighted average price of a share of our common stock for the five trading days immediately prior to the maturity date.
On November 1, 2023, we entered into an amended and restated promissory note whereby the principal amount was reduced to $650,000. The loan matures on December 31, 2024, bears interest at a rate of 6.0% per annum, and has no conversion features. Further, the loan required us to make a payment of $300,000 by December 31, 2023, which was paid.
April 2023 Convertible Note
In April 2023, we entered into separate subscription agreements for the issuance of convertible promissory notes (the “April 2023 Convertible Notes”) in the aggregate principal amount of $2,195,034 and an aggregate amount of 3,658,390 warrants (the “April 2023 Convertible Note Warrants”). The April 2023 Convertible Notes are convertible into shares of our common stock at $0.60 per share. For each share into which an April 2023 Convertible Note is convertible, the investor received April 2023 Convertible Note Warrants to purchase an equal amount of shares of our common stock at $0.60 per share, exercisable for a period of 5 years. In connection with the issuance of the April 2023 Convertible Notes and the April 2023 Convertible Note Warrants, in consideration for its services in respect of the financing described above, we also issued the Placement Agent purchase warrants (the “Placement Agent Warrant”) to purchase 209,670 shares of our common stock at a price per share of $0.60. The Placement Agent Warrant has a 5-year term. In addition, we paid the Placement Agent a commission of approximately $125,000.
In April 2023, we entered into a subscription agreement with Dr. Huh to settle $1,130,775 in related party loans made to us. We issued a $1,130,775 related party unsecured convertible promissory note, with the same terms as the April 2023 Convertible Notes, and warrants to purchase 1,884,625 shares of our common stock, with the same terms as the April 2023 Convertible Note Warrants.
As at December 31, 2023, the April 2023 Convertible Notes were in default.
December 2023 Convertible Note
In December 2023, we entered into additional subscription agreements for the issuance of convertible promissory notes, pursuant to which we issued convertible notes in the aggregate principal amount of $1,000,000 (the “December 2023 Convertible Notes”). In addition, certain holders of April 2023 Convertible Notes agreed to exchange the aggregate amount of $187,950 of April 2023 Convertible Notes, including the accrued interest, into the same amount of December 2023 Convertible Notes.
In January 2024, we completed an additional close of the December 2023 Convertible Notes pursuant to which (i) we issued December 2023 Convertible Notes in the aggregate principal amount of $675,000 and (ii) certain April 2023 Convertible Notes previously issued in the aggregate original principal amount of $240,000 were exchanged for December 2023 Convertible Notes.
In February 2024, we completed a final closing of the December 2023 Convertible Notes and entered into separate subscription agreements in the aggregate principal amount of $63,000.
The December 2023 Convertible Notes bear an interest rate of 10% per annum and have a maturity date of December 18, 2024. The terms of the December 2023 Convertible Notes provide for automatic conversion of the outstanding principal amount of the December 2023 Convertible Notes and all accrued and unpaid interest upon a business combination (as defined in the agreement) into our common stock at the Conversion Price (the “Automatic Conversion Feature”). The Conversion Price is determined by reference to the purchase price payable in connection with such business combination, multiplied by 70%, where
103
the price per share of the common stock is determined by reference to the 30-day volume weighted average price of our common stock on the public exchange immediately prior to conversion, resulting in 43% discount on the issuance price in the a business combination (the Automatic Discount”). If a business combination does not occur prior to the maturity date of the December 2023 Convertible Notes and if our Common Stock is listed on a public exchange as of such date, then the holders have the right, at their option, to convert the outstanding principal amount of the December 2023 Convertible Notes (and all accrued and unpaid interest thereof) into the shares of our common stock at a price equal to the 30-day volume weighted average price of our common stock on the public exchange on which it is traded multiplied by 90% (the “Optional Conversion Feature”).
In consideration for its services in respect of the financing described above, we paid the Placement Agent a commission of $147,040. Further, upon conversion of the December 2023 Convertible Notes into our Common Stock, the Placement Agent will receive shares of our restricted Common Stock equal to (i) 4% of the total number of shares of Common Stock received upon conversion of the December 2023 Convertible Notes issued for the aggregate principal of $1,738,000 new capital and (ii) 1% of the total number of shares of Common Stock received upon conversion of the December 2023 Convertible Notes issued for the aggregate principal of $420,000 in exchange of the April 2023 Convertible Notes.
In December 2023, we issued a $500,000 related party December 2023 Convertible Note to Dr. Huh. This note has the same terms as the December 2023 Convertible Notes outlined above.
May 2024 Convertible Notes
In May 2024, the Company entered into a secured convertible promissory note agreement pursuant to which the Company issued convertible notes in the aggregate principal amount of $1,324,500 (the “May 2024 Convertible Notes”).
In July 2024, the Company completed a final closing of the May 2024 Convertible Notes and entered into a secured convertible promissory note agreement pursuant to which the Company issued convertible notes in the aggregate principal amount of $2,175,000 (the “May 2024 Convertible Notes”).
The May 2024 Convertible Notes carry an interest rate of 10% per annum, have a maturity date of December 18, 2024. The terms of the May 2024 Convertible Notes provide for automatic conversion of the outstanding principal amount of the notes and all accrued and unpaid interest upon a business combination (as defined in the agreement) into the Company common stock at the Conversion Price. The Conversion Price is determined by reference to the purchase price payable in connection with such business combination, multiplied by 50%, where the price per share of the common stock is determined by reference to the 30-day volume weighted average price of our common stock on the public exchange immediately prior to conversion. In conjunction with the May 2024 Convertible Notes, we entered into the Security Agreement which grants and assigns the May 2024 convertible note holders a senior security interest in all of the assets of the Company and its subsidiaries.
In consideration for its services in respect of the financing described above, the Company paid Paulson Investment Company, LLC (the “May 2024 Placement Agent”) the commission of $200,000. Further, upon conversion of the May 2024 Convertible Notes into Common Stock of the Company, the May 2024 Placement Agent will receive shares of restricted common stock of the Company equal to 4% of the total number of shares of common stock received upon conversion of May 2024 Convertible Notes on certain notes with a principal value of $2,500,000.
White Lion Common Stock Purchase and Registration Rights Agreements
On November 3, 2022, we entered into a Common Stock Purchase Agreement (the “White Lion Purchase Agreement”) and Registration Rights (the “White Lion RRA”) with White Lion Capital, LLC, a Delaware limited liability company (“White Lion”). Pursuant to the White Lion Purchase Agreement, we have the right, but not the obligation, to require White Lion to purchase, from time to time, up to $100,000,000 in aggregate gross purchase price of newly issued shares of our Common Stock, subject to certain limitations and conditions set forth in the White Lion Purchase Agreement. Capitalized terms used but not otherwise defined in this section shall have the meanings given to such terms by the White Lion Purchase Agreement and the White Lion RRA.
We are obligated under the White Lion Purchase Agreement and the White Lion RRA to file a registration statement with the SEC to register the Common Stock under the Securities Act, for the resale by White Lion of shares of Common Stock that we may issue to White Lion under the White Lion Purchase Agreement.
Subject to the satisfaction of certain customary conditions including, without limitation, the effectiveness of a registration statement registering the shares issuable pursuant to the White Lion Purchase Agreement, our right to sell shares to White Lion will commence on the effective date of the registration statement and extend until November 1, 2025. During such term, subject to the terms and conditions of the White Lion Purchase Agreement, we may notify White Lion when we exercise our right to sell shares (the effective date of such notice, a “Notice Date”).
The number of shares sold pursuant to any such notice may not exceed (i) the lower of (a) the Purchase Notice Fixed Limit (described below) and (b) the product of (1) the Average Daily Trading Volume (as defined in the White Lion Purchase
104
Agreement), and (2) the applicable Percentage Limit (as defined in the White Lion Purchase Agreement). The Purchase Notice Fixed Limit is $500,000 upon payment of the Initial Commitment Shares (as defined in the White Lion Purchase Agreement) and can be increased in two tranches: (A) to $1,000,000 following an aggregate purchase of $5,000,000 shares and issuance by us to White Lion of an additional $250,000 in Commitment Shares, and (B) to $2,000,000 following an aggregate purchase of $10,000,000 shares and issuance by the for payment of an additional $250,000 in Commitment Shares (as defined in the White Lion Purchase Agreement).
The applicable Percentage Limit is 40% or 150% depending on the price we agree to sell shares to White Lion. At an applicable Percentage Limit of 40%, the Purchase Price to be paid by White Lion for any such shares will equal 97% of lowest daily volume-weighted average price of Common Stock during a period of two consecutive Trading Days following the applicable Purchase Notice Date (as defined in the White Lion Purchase Agreement) until an aggregate of $50,000,000 in Purchase Notice Shares (as defined in the White Lion Purchase Agreement) have been purchased under White Lion Purchase Agreement, at which point the Purchase Price (as defined in the White Lion Purchase Agreement) to be paid by White Lion will equal 98% of the lowest daily volume-weighted average price of Common Stock during a period of two consecutive Trading Days following the applicable Purchase Notice Date. At an applicable Percentage Limit of 150%, the Purchase Price to be paid by White Lion for any such shares will equal 94.5% of the lowest daily volume-weighted average price of Common Stock during a period of three consecutive Trading Days following the applicable Purchase Notice Date.
We will have the right to terminate the White Lion Purchase Agreement at any time after commencement, at no cost or penalty, upon three (3) Trading Days’ prior written notice. Additionally, White Lion will have the right to terminate the White Lion Purchase Agreement upon three (3) days’ prior written notice to us if (i) there is a Fundamental Transaction (as defined in the White Lion Purchase Agreement), (ii) we are in breach or default in any material respect of the White Lion RRA, (iii) there is a lapse of the effectiveness, or unavailability of, the registration statement for a period of 45 consecutive Trading Days or for more than an aggregate of 90 Trading Days in any 365-day period, (iv) the suspension of trading of the Common Stock for a period of five (5) consecutive Trading Days, (v) the material breach of the White Lion Purchase Agreement by us, which breach is not cured within the applicable cure period or (vi) a Material Adverse Effect (as defined in the White Lion Purchase Agreement) has occurred and is continuing. No termination of the White Lion Purchase Agreement will affect the registration rights provisions contained in the White Lion RRA.
In consideration for the commitments of White Lion, as described above, we have agreed that it will issue to White Lion shares of Common Stock having a value of $250,000 based upon the Closing Sale Price (as defined in the White Lion Purchase Agreement) of Common Stock two Trading Days prior to the filing of the Initial Registration Statement as Initial Commitment Shares. We may increase the number of shares it may sell to White Lion by issuing additional Commitment Shares in two additional tranches of $250,000 each. We issued Initial Commitment Shares of 50,200 shares of Common Stock to White Lion, based upon the Closing Sale Price of our Common Stock of $4.98 per share on November 30, 2022.
Concurrently with the execution of the White Lion Purchase Agreement, we entered into the White Lion RRA with White Lion in which we have agreed to register the shares of Common Stock purchased by White Lion with the SEC for resale within 30 days of the consummation of a business combination. The White Lion RRA also contains usual and customary damages provisions for failure to file and failure to have the registration statement declared effective by the SEC within the time periods specified.
The White Lion Purchase Agreement and the White Lion RRA contain customary representations, warranties, conditions and indemnification obligations of the parties. The representations, warranties and covenants contained in such agreements were made only for purposes of such agreements and as of specific dates, were solely for the benefit of the parties to such agreements and may be subject to limitations agreed upon by the contracting parties.
In March 2023, we entered into an amendment to the White Lion Purchase Agreement to give us the right, but not the obligation to require White Lion to purchase shares of our common stock while trading on the OTC Market. Under the terms of the amendment, we will issue to White Lion within five (5) Trading Days following the effective date of the amendment fully paid, non-assessable shares of our Common Stock equal to the quotient obtained by dividing (i) $250,000 and (ii) the lowest traded sale price of the common stock of the 10 (ten) Trading Days prior to the effective date of the amendment, minus 50,200. In March 2023, as compensation for its commitment to enter into the amendment, we issued 412,763 shares of our common stock to White Lion.
In August 2023, we and White Lion entered into a second amendment to the Common Stock Purchase Agreement (the “Second Amendment”). The Second Amendment includes, among other things, the right of the Company to issue a Purchase Notice (defined in the Second Amendment as an “Accelerated Purchase Notice”) requesting White Lion to purchase newly issued shares of common stock from us, subject to acceptance by White Lion, with pricing of the shares to be sold by us to White Lion under such Accelerated Purchase Notice determined on the date of issuance by us of the Accelerate Purchase Notice and acceptance by White Lion (the date of such notice defined as the “Accelerated Valuation Period”). Such accelerated purchases pursuant to an Accelerated Purchase Notice will be sold to White Lion at a price, defined as an “Accelerated Purchase Price,”
105
equal to the lower of (i) the opening price of common stock during the Accelerated Valuation Period, (ii) the closing price of the common stock during Accelerated Valuation Period, or (iii) the volume weighted average price of the common stock during Accelerated Valuation Period; provided, however, that if at the time we deliver an Accelerated Purchase Notice to Investor the price of the common stock is lower than the opening price of the common stock during the Accelerated Valuation Period, the Accelerated Purchase Price will be discounted by 20%. In addition, the Second Amendment provides for an “Accelerated Purchase Notice Limit” equal to 200%.
In addition, in the event we do not issue Purchase Notices (as defined in the White Lion Purchase Agreement) to White Lion providing for the purchase of at least $1,250,000 of Purchase Shares (as defined in the White Lion Purchase Agreement and Second Amendment) in the aggregate within 180 days following the effective date of the amendment, we will issue to White Lion an additional number of fully paid, non-assessable shares of common stock equal to the quotient obtained by dividing (i) $150,000 and (ii) the lowest Closing Sale Price (as defined in the White Lion Purchase Agreement and Second Amendment) of common stock of the 10 (ten) Trading Days prior to the 180th day following the effective date of the amendment.
During September 2023, we issued the notices to purchase the total of 729,000 common shares to White Lion for the total proceeds of $105,317.
Release of Certain Lock-Up Restrictions
In order to comply with Nasdaq listing requirements, on January 4, 2023, we released 30% of the Target Consideration Shares (excluding shares held by Dr. Huh) from the six-month lock-up restrictions entered into in connection with the Business Combination (representing a total of 3,057,599 shares for release, of which, we estimate that approximately one-third will have been purchased below the closing price of our Common Stock of $4.21 on December 29, 2022). The release of those shares from lock-up restrictions may cause the market price of our securities to decline or increase the volatility in the market price of our securities. Additionally, since the Target Consideration Shares that may be offered for resale pursuant to this prospectus represent approximately 88% of the shares outstanding as of December 29, 2022 (after giving effect to redemptions and repurchases), the sale of all the securities being offered in this prospectus, or the perception that these sales could occur, could result in a significant decline in the public trading price of our securities.
Components of Results of Operations
Results prior to the Spin-Off
Prior to March 1, 2022, we operated as pH Pharma Ltd, a Korean company. Effective March 1, 2022, we spun off certain assets to a newly formed company in Korea (the “Spin-Off”). The Spin-Off resulted in the Company retaining the PHP-303 and PH-1 ADC Platform programs. Prior to April 1, 2022, our consolidated financial statements have been extracted from the accounting records of pH Pharma, Ltd. on a carve-out basis. The historical results of operations, financial position, and cash flows may not be indicative of what we would have been had we been a separate stand-alone entity, nor are they indicative of what the results of operations, financial position and cash flows may be in the future.

The historical results of operations, financial position, and cash flows may not be indicative of what we would have been had we been a separate stand-alone entity, nor are they indicative of what the results of operations, financial position and cash flows may be in the future.
Revenue
Our revenue has historically been generated through grants from government organizations. We currently have no commercially approved products. Grant revenue is recognized during the period that the research and development services occur, as qualifying expenses are incurred or conditions of the grants are met. Qualifying expenses are recognized when incurred as research and development expenses. Expenses for grants are tracked by using a project code specific to the grant, and the employees also track hours worked by using the project code.
Grant Revenue
Our grant revenues are derived from research programs with the Department of Defense, US Army Medical Research Acquisition Activity for work on a COVID-19 therapeutic.
Grants awarded to us for research and development by government entities are outside the scope of the contracts with customers and contributions guidance. This is because these granting entities are not considered to be customers and are not receiving reciprocal value for their grant support provided to us. These grants provide us with payments for certain types of expenditures in return for research and development activities over a contractually defined period.
106
We recognize grant revenue based on the reimbursable costs that are incurred during the period, up to pre-approved award limits. The expenses associated with these reimbursements are reflected as a component of research and development expense in our consolidated statements of operations and comprehensive loss.
Research and Development Expense
We expense research and development costs as incurred. Research and development expense consist primarily of costs related to personnel, including salaries and other personnel related expenses, contract manufacturing and supply, consulting fees, and the cost of facilities and support services used in drug development. Assets acquired that are used for research and development and have no future alternative use are expensed as in-process research and development.
General and Administrative Expenses
General and administrative expenses consist primarily of salaries and related benefits, including stock-based compensation, related to our executive, finance, business development, legal, human resources and support functions. Other general and administrative expenses include professional fees for auditing, tax, consulting and patent-related services, rent and utilities and insurance.

Research and development expense decreased by $2.3 million during the year ended December 31, 2023 compared to the prior year. The decrease was primarily due to decreases in direct project expenses related to the PHP-303 program of $68,682, the PH-1 ADC Platform of $309,298 and other general and pre-clinical programs of $222,365 as a result of delays in our ongoing and planned research activities. In addition, there was a decrease in personnel costs and facilities costs of $0.6 million and $1 million
107
driven by a reduction of staff and overhead. We reduced our average headcount from 21 to 6 employees as well as moved to a smaller facility as a result of scaling back our clinical activities.
General and Administrative Expense
General and administrative expense decreased by $0.2 million during the year ended December 31, 2023 compared to the prior year. The decrease was primarily driven by a reduction in facilities expenses and reduction in headcount for general and administrative employees.
Impairment Loss on Operating Lease Right-of-Use Asset
We recognized an impairment loss on the operating lease right-of-use asset of $3.5 million due to the abandonment of the premises in Palo Alto, California during the year ended December 31, 2023.
Other Income (Expense), Net
Other income (expense), net increased by $1.6 million during the year ended December 31, 2023 as compared to the prior year, primarily due to the gain from the changes in the fair value of the warrant liability and derivative liabilities, partially offset by the increase in interest expense.
We recognized additional $2.7 million in interest expense, including the amortization of related discounts, during the year ended December 31, 2023 as compared to the prior year, related to the November 2022 Convertible Notes, April 2023 Convertible Notes and December 2023 Convertible Notes.
During the year ended December 31, 2023, we recognized a $2.1 million gain from the change in the fair value of the warrant liability primarily related to the warrants issued in April 2023 to the holders of the April 2023 Convertible Notes. We recognized $0.8 million gain from the change in the fair value of the derivative liabilities related to the April 2023 Convertible Notes and December 2023 Convertible notes. These gains are related to the decrease in the price of the Company’s stock.
During the year ended December 31, 2022, we recognized a $1.2 million loss on the change in the fair value of the convertible notes primarily related to increase in the fair value of the 2022 Pre-Business Combination Convertible Notes between their issuance date and the closing date of the Ignyte Business Combination.
Liquidity and Capital Resources
Sources of Liquidity
Since our inception, we have not generated any revenue from product sales and have incurred significant operating losses and negative cash flows from our operations. Our net loss was $12.8 million and $13.1 million for the years ended December 31, 2023 and 2022, respectively. At December 31, 2023 we had cash of $0.4 million. In 2023, we received proceeds of $3.7 million from the issuance of convertible debt and $250,000 from a loan with our founder and director, Dr. Huh. Our primary uses of cash to date have been to fund our research and development activities, business planning, establishing and maintaining our intellectual property portfolio, capital investments and providing general and administrative support for our operations.
Since the beginning of 2024, we raised aggregate gross proceeds of approximately $0.7 million from the issuance of December 2023 Convertible Notes and $1.3 million from the issuance of May 2024 Convertible Notes.
Funding Requirements
We expect to incur losses from operations for the foreseeable future primarily due to research and development expenses, including expenses related to conducting research activities, pre-clinical expenses and clinical trials. Our future capital requirements will depend on a number of factors, including:
108
We expect to incur significant expenses and operating losses for the foreseeable future as we continue our efforts to identify product candidates and seek regulatory approvals within our gene therapy portfolio.
Additional financing will be needed to fund our ongoing activities. We may raise this additional funding through the sale of equity, debt financings or other capital sources, including potential collaborations with other companies or other strategic transactions and funding under government contracts. We may be unable to raise additional funds or enter into such other arrangements or arrangement when needed on favorable terms, or at all. If we are unable to raise capital when needed or on attractive terms, we could be forced to delay, reduce or eliminate certain of our research and development programs. There can be no assurances that other sources of financing would be available. Due to these uncertainties, there is substantial doubt about our ability to continue as a going concern.
Our future operations are highly dependent on a combination of factors, including (i) the timely and successful completion of additional financing; (ii) the success of our research and development programs; (iii) the development of competitive therapies by other biotechnology and pharmaceutical companies, (iv) our ability to attract and retain key employees, (v) our ability to manage growth of the organization; (vi) our ability to protect our proprietary technology; and ultimately (vii) regulatory approval and market acceptance of our product candidates.

Operating Activities
Net cash used in operating activities was approximately $4.8 million and $7.5 million for the years ended December 31, 2023 and 2022, respectively. The decrease in operating spending was a result of our reduction in facilities expenses, reduction in headcount of general and administrative employees,and decreases in direct project expenses related to the PHP-303 program, the
109
PH-1 ADC Platform, and other general and pre-clinical programs as a result of delays in our ongoing and planned research activities.
Investing Activities
During the year ended December 31, 2022, net cash used in investing activities was $142,249, primarily due to capital expenditures for furniture and fixtures related to the office in South San Francisco, California.
Financing Activities
During the year ended December 31, 2023 net cash provided by financing activities was $4.2 million, including the proceeds from the issuance of convertible notes of $3.4 million, proceeds from a related party loan of $0.25 million, proceeds from the issuance of common stock for $1.1 million partially offset by repayments on convertible notes of $0.3 million and repayments on insurance financing of $0.3 million.
During the year ended December 31, 2022, net cash provided by financing activities was $8.1 million including the proceeds from the issuance of long-term debt of $1.3 million, proceeds from a related party loan of $0.5 million, proceeds from the Business Combination with Ignyte of $3.9 million, and the issuance of common stock for $5.2 million partially offset by the $3.8 million settlement of the Forward Share Purchase agreement assumed from Ignyte in the Business Combination.
Contractual Obligations and Commitments
In October 2021, we entered into a lease for laboratory and office facilities in Palo Alto, California that expires in March 2027 with a five-year renewal option and opened a secured letter of credit with a third-party financial institution in lieu of a security deposit for $177,000. Base rent for this sublease is approximately $89,000 monthly with annual escalations of 3%. In March 2023, we vacated the premises and returned possession of the premises to the landlord in April 2023. We are still responsible for the outstanding payments under the lease.
At the date of the Spin-Off, we and pH Pharma Co., Ltd entered into an administrative services and facilities agreement whereby pH Pharma Co., Ltd would perform services, functions and responsibilities for us. Under the agreement, we paid pH Pharma Co., Ltd $100,000 per month through August 30, 2022 and $15,000 per month from September 1, 2022 through February 28, 2023 based on the estimated value of the level of service to be performed. Additionally, we reimbursed pH Pharma Co., Ltd $3,000 per month in lease payments from the date of the Spin-Off through February 28, 2023. At December 31, 2023 and 2022, the amounts payable to pH Pharma Co., Ltd under this agreement totaled $309,534 and $426,673, respectively, included in accounts payable in the consolidated balance sheets. On January 31, 2024, we and pH Pharma Co., Ltd entered into a settlement agreement, settled the outstanding debt for a one-time payment of $85,000, resulting in a gain on debt extinguishment of $207,967, and terminated the administrative services and facilities agreement.
Off-Balance Sheet Arrangements
We had no off-balance sheet arrangements as of December 31, 2023 and 2022.
Critical Accounting Policies and Significant Judgments and Estimates
Our discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements included within this Annual Report on Form 10-K, which we have prepared in accordance with U.S. GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, as well as the reported expenses during the reporting periods. On an ongoing basis, we evaluate our estimates and judgments, including those described in greater detail below. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
We believe that the following discussion represents our critical accounting policies.
Grant Revenue
Our grant revenues are derived from research programs with the Department of Defense, US Army Medical Research Acquisition Activity for work on a COVID-19 therapeutic.
110
Grants awarded to us for research and development by government entities are outside the scope of the contracts with customers and contributions guidance. This is because these granting entities are not considered to be customers and are not receiving reciprocal value for their grant support provided to us. These grants provide us with payments for certain types of expenditures in return for research and development activities over a contractually defined period.
We recognize grant revenue based on the reimbursable costs that are incurred due the period, up to pre-approved award limits. The expenses associated with these reimbursements are reflected as a component of research and development expense in the accompanying consolidated statements of operations and comprehensive loss.
Share-based Compensation
We account for stock option awards in accordance with ASC 718, Compensation-Stock Compensation (“ASC 718”). The estimated grant date fair value of the stock option awards are recognized as compensation expense over the requisite service period of the awards (usually the vesting period) on a straight-line basis. We estimate the fair value of each stock-based award on the date of grant using the Black-Scholes option pricing model. The Black-Scholes option pricing model incorporates various assumptions, such as the value of the underlying common stock, the risk-free interest rate, expected volatility, expected dividend yield, and expected life of the options. Expected volatility is based on the historical volatility of a publicly traded set of peer companies. Our historical share option exercise experience does not provide a reasonable basis upon which to estimate an expected term because of a lack of sufficient data. Therefore, we estimate the expected term by using the simplified method, which calculates the expected term as the average of the time-to-vesting and the contractual life of the options. The risk-free interest rate is based on U.S. Treasury, zero-coupon issues with a remaining term equal to the expected life assumed at the date of grant (or modification, as applicable). Equity-based compensation expense is classified in the statements of operations in the same manner in which the award recipients’ payroll costs or service payments are classified. Forfeitures are recognized as a reduction of stock-based compensation expense as they occur.
Derivative Instruments
We issued warrants to its investors and accounts for warrant instruments as either equity-classified or liability-classified instruments based on an assessment of the specific terms of the warrants and applicable authoritative guidance in ASC 480 and ASC 815, “Derivatives and Hedging” (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to our own stock and whether the holders of the warrants could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification.
The Key Company Stockholder Forward Purchase Liability entered into on April 28, 2022 resulted in us holding a put option on shares to be purchased. The Forward Share Purchase Agreement entered into on October 22, 2022 resulted in us holding a put option on shares to be purchased. The White Lion Purchase Agreement includes an embedded put option and an embedded forward option (see Note 11). Pursuant to ASC 815, these instruments meet the definition of a derivative and accordingly were recognized at fair value and are remeasured at fair value at each period end.
Recently Issued Accounting Standards
A description of recently issued accounting pronouncements that may potentially impact our financial position and results of operations is disclosed in Note 2, Summary of Significant Accounting Policies, to our audited consolidated financial statements appearing elsewhere in this Annual Report on Form 10-K.

Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with U.S. GAAP. Under standards established by the Public Company Accounting Oversight Board, or PCAOB, a deficiency in internal control over financial reporting exists when the design or operation of a control does not allow management or personnel, in the normal course of performing their assigned functions, to prevent or detect misstatements on a timely basis. The PCAOB defines a material weakness as a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of annual or interim financial statements will not be prevented, or detected and corrected, on a timely basis.
111
JOBS Act Accounting Election
We qualify as an “emerging growth company” as defined in the JOBS Act. An emerging growth company may take advantage of reduced reporting requirements that are not otherwise applicable to public companies. These provisions include, but are not limited to:
We may use these provisions until the last day of our fiscal year in which the fifth anniversary of the completion of this offering occurs. However, if certain events occur prior to the end of such five-year period, including if we become a “large accelerated filer,” our annual gross revenue exceeds $1.235 billion, or we issue more than $1.0 billion of non-convertible debt in any three-year period, we will cease to be an emerging growth company prior to the end of such five-year period.
We have elected to take advantage of certain of the reduced disclosure obligations in this Annual Report on Form 10-K and may elect to take advantage of other reduced reporting requirements in future filings. As a result, the information that we provide to our shareholders may be different than the information you receive from other public companies in which you hold stock.
The JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards, until those standards apply to private companies. We have elected to take advantage of the benefits of this extended transition period and, therefore, we will not be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies. Our financial statements may therefore not be comparable to those of companies that comply with such new or revised accounting standards. Until the date that we are no longer an emerging growth company or affirmatively and irrevocably opt out of the exemption provided by Section 7(a)(2)(B) of the Securities Act upon issuance of a new or revised accounting standard that applies to our financial statements and that has a different effective date for public and private companies, we will disclose the date on which we will adopt the recently issued accounting standard.
112
Item 7A. Quantitative and Qualitative Disclosures About Market Risk.
Concentration of Credit Risk
We received 100% of our revenue through a grant from a government organization during the years ended December 31, 2023 and 2022. To date, no receivables have been written off.
Interest Rate Risk
As of December 31, 2023 and 2022, we had a cash balance of $0.4 million and $0.6 million, respectively, all of which were maintained in business checking accounts and money market accounts in the U.S. and South Korea. Our primary exposure to market risk is to interest income volatility, which is affected by changes in the general level of interest rates. As such rates are at a near record low, a 10% change in the market interest rates would not have a material effect on our business, financial condition or results of operations.
Foreign Currency Risk
We conduct our business in U.S. dollars and, thus, are not exposed to financial risks from exchange rate fluctuations between the U.S. dollar and other currencies.
Item 8. Financial Statements and Supplementary Data.
Our consolidated financial statements, together with the reports of our independent registered public accounting firms, appear beginning on page F-1 of this Annual Report on Form 10-K for the year ended December 31, 2023.
Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure.
None.
Item 9A. Controls and Procedures.
Disclosure Controls and Procedures
Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2023. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, mean controls and other procedures of a company that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms. Disclosure controls include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to management, including our principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of December 31, 2023, our chief executive officer and chief financial officer concluded that, as of such date, our internal controls over financial reporting were not effective as of the end of the period covered by this Annual Report on Form 10-K due to material weaknesses as describe herein.
A material weakness is a control deficiency (within the meaning of the Public Company Accounting Oversight Board (United States) Auditing Standard No. 2) or combination of control deficiencies that result in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. Management has identified the following material weaknesses:
113
Planned Remediation
Management continues to work to improve its controls related to our material weaknesses, specifically implementing improved processes and internal controls to ensure the proper application of accounting practices and guidance. We also intend to increase our accounting staff as soon as economically feasible and sustainable to remediate these material weaknesses. These material weaknesses will not be considered to be remediated until the applicable remediated controls are operating for a sufficient period of time and management has concluded that these controls are operating effectively.
Management’s Annual Report on Internal Controls Over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). Our internal control system was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes, in accordance with generally accepted accounting principles in the United States. Due to inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness of the internal control over financial reporting to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies and procedures may deteriorate. Our management, under the supervision and with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our internal control over financial reporting as of the end of the period covered by this Annual Report on Form 10-K based on the framework in Internal Control---Integrated Framework (2013 framework) issued by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO. Based on such evaluation, our management concluded that our internal control over financial reporting was not effective as of the end of the period covered by this Annual Report on Form 10-K.
This Annual Report on Form 10-K does not include an attestation report on internal control over financial reporting issued by our independent registered public accounting firm. Our auditors will not be required to opine on the effectiveness of our internal control over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act of 2002 until we are no longer (i) an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 or (ii) a non-accelerated filer, as defined under the Exchange Act.
Changes in Internal Control Over Financial Reporting
Except as noted above, there was no change in our internal control over financial reporting that occurred during the fiscal year ended December 31, 2023 covered by this Annual Report on Form 10-K that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
Inherent Limitation on the Effectiveness of Internal Control
Our management, including our Interim Chief Executive Officer and Acting Chief Financial Officer, does not expect that our disclosure controls and procedures, or our internal controls, will prevent all error and all fraud. A control system, no matter
114
how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our Company have been detected.
Item 9B. Other Information.
During the fourth quarter of 2023, our directors and/or executive officers (as defined in Section 16 of the Exchange Act) did not
During the fourth quarter of 2023, the Company did not adopt or terminate a Rule 10b5-1 trading arrangement (as defined in Item 408(a)(1)(i) of Regulation S-K).
Item 9C. Disclosure Regarding Foreign Jurisdictions that Prevent Inspections.
None.

Executive Officers
Hoyoung Huh, MD, PhD, is the founder of Peak Bio Co., Ltd. (f/k/a pH Pharma) and has held positions of Chief Executive Officer and Board Chairman since founding pH Pharma in 2015. He currently serves as a director on the board of directors (the “Board”) of the Company. Dr. Huh is a Silicon Valley-based entrepreneur and investor in healthcare and technology-based businesses and has served as Lead Director of Pliant Therapeutics since December 2017. Dr. Huh was a Managing Director of Konus Advisory Group, Inc. from January 2012 to September 2014. Prior to founding Konus Advisory Group, Inc., Dr. Huh was Chief Executive Officer and Chairman of the board of directors of BiPar Sciences, Inc. from February 2008 until December 2010. In addition, Dr. Huh has been involved in the formation, management and board positions of multiple biotechnology and innovation-based companies. He previously served as the Chairman of the board of directors of Geron Corporation from September 2011 to December 2018, and CytomX Therapeutics, Inc. from February 2012 to December 2018, a member of the board of directors of Rezolute, Inc. (f/k/a AntriaBio, Inc.) from 2013 to January 2019, the Chairman of the board of directors of Epizyme, Inc. from October 2009 to February 2012, and as a member of the board of directors of Facet Biotech Corporation, Nektar Therapeutics, Inc., Addex Therapeutics Ltd. and EOS, S.p.A (Milano, Italy). Earlier in his career, Dr. Huh was a partner at McKinsey & Company. He holds A.B. in Biochemistry from Dartmouth College, an M.D. from Cornell University Medical College and a Ph.D. in Cell Biology and Genetics from Cornell University Sloan Kettering Institute. We believe Dr. Huh’s extensive management and operational experience as President and Chief Executive Officer of numerous biotechnology companies and his significant knowledge and expertise of biotechnology and pharmaceutical collaborations, qualifies Dr. Huh to serve as a director and Chairman of the Board of Peak Bio.
Stephen LaMond, PharmD, MBA, has been the Chief Operating Officer and Secretary of Peak Bio Co., Ltd. since March 1, 2022. He currently serves as Interim Chief Executive Officer and as a director of the Company. Prior to his current role, Dr. LaMond has been both an employee and independent consultant to Peak Bio (f/k/a pH Pharma). Peak Bio consists of the merged entity of Ignyte and the selected assets from pH Pharma. Dr. LaMond served as both a consultant and one of the original executives with pH Pharma and its affiliated companies serving in corporate and business development roles in addition to
116
serving in a clinical program management capacity. Dr. LaMond has been directly involved with pH Pharma in both the U.S. and Korea and now at Peak Bio since 2016. Dr. LaMond has previously held management and executive roles in marketing, new product planning, corporate and business development at numerous companies including Tria Beauty, Corium International, Zoll Medical, GE Healthcare, Nektar Therapeutics and Pfizer Inc. across multiple therapeutic areas and has worked on some of the most innovative products over his tenure. Dr. LaMond received his PharmD and Executive MBA degrees from the University of Michigan, Ann Arbor and has executive finance training from Columbia and Stanford Universities. We believe Dr. LaMond’s extensive experience in operations, business development, corporate development, marketing, regulatory and market access with biopharmaceutical and biotechnology companies qualifies him to serve on the Board.
Timothy Cunningham, MBA, CPA, serves as the Acting Chief Financial Officer of the Company following the closing of the Business Combination. He brings more than 30 years of finance and operations leadership experience in the life sciences and technology industries with a proven track record of driving growth. He is currently Chief Financial Officer at Danforth Advisors, a company that provides strategic and operational finance and accounting support for life science companies. Prior to joining Danforth, Mr. Cunningham served as Chief Financial Officer at Organogenesis, where he took the company public and raised over $250M in equity and debt financing to facilitate the company’s growth. Earlier, he held leadership positions with DialogTech, GFI Software SA, Metatomix, Mediabridge, IBM, PWC, and KPMG. Tim holds an MBA from Boston University, a BS in Accounting from Boston College and is a CPA in the state of Florida.
Divya Patel, CPA, serves as the Corporate Controller of Peak Bio Inc. In this role, she has overall responsibility for the financial reporting activities for Peak Bio Inc. and its global subsidiaries. She has served as controller and treasurer in the private sector for medical device companies including the international brand Tria Beauty. Ms. Patel has over 10 years experience in finance and accounting experience and holds a Certified Public Accountant designation. Ms. Patel has also served as an auditor and international tax manager with accounting firms in Canada, including Canadian national firm MNP LLP. She obtained her Bachelors in Business Administration from Simon Fraser University and also holds a Chartered Professional Accounting Designation in Canada.
Satyajit Mitra, PhD, is the Executive Director and Head of Oncology for Peak Bio. As the Head of Oncology, he has been responsible for Peak Bio Co., Ltd.’s preclinical research activities at our CA research sites since January 2021. Dr. Mitra heads up a team of talented research associates, scientists, consultants, CROs and CDMOs and has been instrumental in advancing our novel toxin platform and ADC pipeline. From March 2019 to December 2020, Dr. Mitra headed up Cancer Biology at Peak Bio Co., Ltd. and was responsible for in vivo and pharmacology functions that led to the nomination of the current Peak Bio lead toxin (PH1), which then led to Peak Bio’s initial proof-of-concept (POC) efforts for an ADC. These POC efforts led to the nomination of Peak Bio’s first ADC pipeline candidate targeting Trop2. He previously served as a Senior Scientist, at VasGene Therapeutics, and was involved with IND-enabling studies for novel antibody targets. Dr. Mitra’s initial corporate scientific experience was at OncoMed Pharmaceuticals for 5 years where he worked on Target Validation. He was instrumental in identifying the first-in-class Wnt-pathway biologics, advancing these projects from early stage to an IND. In addition to Dr. Mitra’s oncology company experiences, he also previously worked as a research scientist at the University of Southern California in Los Angeles. He completed his postdoctoral fellowship at the Department of Immunology at Scripps Research Institute at La Jolla, California. He obtained his Ph.D. from the Centre for Cellular and Molecular Biology at Hyderabad, India an institute affiliated with the Jawaharlal Nehru University (JNU), New Delhi, India.
Non-Employee Directors
James Neal, MS, MBA serves as a director on the Board of the Company. He comes to Peak Bio’s board of directors as an experienced business professional serving as XOMA Corporation’s Chief Executive Officer and Chairman of the Board, joining that company in 2009. Mr. Neal brings more than 25 years’ experience in forming and maximizing business and technology collaborations globally and in bringing novel products and technologies to market. Prior to XOMA, Mr. Neal was Acting Chief Executive Officer of Entelos, Inc., a leading biosimulation company that acquired Iconix Biosciences, a privately held company where Mr. Neal was Chief Executive Officer. At Iconix, Mr. Neal established multi-year collaborations with Bristol-Myers Squibb, Abbott Labs, Eli Lilly and the U.S. Food and Drug Administration. From, 1999-2002, he was Executive Vice President of Incyte Genomics, leading the global commercial activities with pharmaceutical company collaborators and partners including Pfizer, Aventis and Schering-Plough, as well as sales, marketing and business development activities for the company. Earlier, he was associated with Monsanto Company in positions of increasing responsibility. Mr. Neal earned his B.S. in Biology and his M.S. in Genetics and Plant Breeding from the University of Manitoba, Canada, and holds an Executive MBA degree from Washington University in St. Louis, Missouri. We believe Mr. Neal’s significant experience with biopharmaceutical companies, including as a board member and CEO, qualifies him to serve on our board of directors.
David Rosenberg has been Ignyte’s Chairman of the Board and co-Chief Executive Officer since its formation. Mr. Rosenberg serves as a director on the Board of the Company. Mr. Rosenberg brings over 20 years of investment banking experience focused on growth companies. Since December 2011, Mr. Rosenberg has been Co-President and Co-Chief Executive Officer of Ladenburg Thalmann & Co. Inc., a leading underwriter of blank check companies or SPACs. Mr. Rosenberg is also a

Mr. Rosenberg also serves as member of the Board of Directors of Dianomi Therapeutics. Prior to joining Ladenburg Thalmann, from 2004 to 2006, Mr. Rosenberg was co-founder and Chief Executive Officer of BroadWall Capital, LLC, an investment banking firm. Mr. Rosenberg received a B.A. from the University of Wisconsin-Madison. We believe Mr. Rosenberg is well qualified to serve on our board of directors because of his significant investment banking, equity capital markets and executive management experience.
Michael Friedman, MS, MBA serves as a director on the Board of the Company. Mr. Friedman served as Senior Vice President at Ladenburg Thalmann & Co. Inc. Healthcare Investment Banking where he focused on M&A and capital markets from 2017 to 2023.

Previously, Mr. Friedman was an investment banker for Bank of America Merrill Lynch, Jefferies and Baird. He holds an MBA from the University of Chicago, Booth School of Business and he received his BBA from the University of Wisconsin. The Company’s Board of Directors believes Mr. Friedman’s significant experience advising biopharmaceutical companies in M&A and finance qualifies him to serve on our board of directors.
Number and Terms of Office of Officers and Directors of Peak Bio
Our Board is divided into three classes with only one class of directors being elected in each year and each class serving a three-year term.
Our officers are appointed by the board of directors and serve at the discretion of the board of directors, rather than for specific terms of office. Our board of directors is authorized to appoint persons to the offices set forth in our bylaws as it deems appropriate. Our bylaws provide that our officers may consist of a Chairman of the Board, one or more Chief Executive Officers, Chief Financial Officer, President, Vice Presidents, Secretary, Treasurer, Assistant Secretaries and such other offices as may be determined by the board of directors.
Committees of the Board of Directors
The standing committees of our board of directors include an audit committee, a compensation committee and a nominating and corporate governance committee. Each of the committees reports to the board of directors as they deem appropriate and as the board of directors may request. The composition, duties and responsibilities of these committees are set forth below.
Audit Committee
The principal functions of the audit committee include, among other things:
118
Our audit committee consists of James Neal and Michael Friedman, with Mr. Neal serving as the chair of the audit committee. Each of Messrs. Neal and Friedman qualify as independent directors according to the rules and regulations of the SEC with respect to audit committee membership. Mr. Friedman qualifies as our “audit committee financial expert,” as that term is defined in Item 401(h) of Regulation S-K. Our board of directors has adopted a written charter for the Audit Committee, which is available free of charge on our corporate website. The information on our website is not part of this Annual Report on Form 10-K.
Compensation Committee
The principal functions of the compensation committee include, among other things:
Our compensation committee consists of James Neal and Michael Friedman, with Mr. Neal serving as the chair of the compensation committee. Each of Messrs. Neal and Friedman qualify as independent directors according to the rules and regulations of the SEC with respect to compensation committee membership.

Nominating Committee
The principal functions of the nominating committee include, among other things:
The Nominating Committee will consider a number of qualifications relating to management and leadership experience, background and integrity and professionalism in evaluating a person’s candidacy for membership on the board of directors. The nominating committee may require certain skills or attributes, such as financial or accounting experience, to meet specific board needs that arise from time to time and will also consider the overall experience and makeup of its members to obtain a broad and diverse mix of board members. The nominating committee does not distinguish among nominees recommended by stockholders and other persons.
Our Nominating Committee consists of James Neal and David Rosenberg, with Mr. Neal serving as the chair of the Nominating Committee. We expect that our board of directors will adopt a written charter for the Nominating Committee, which
119

In addition, we intend to post on our website all disclosures that are required by law or the listing standards concerning any amendments to, or waivers from, any provision of the code. References to our website address do not constitute incorporation by reference of the information contained at or available through our website, and such information should not be considered to be a part of this Annual Report on Form 10-K. We also intend to disclose any amendments to or waivers of certain provisions of our Code of Ethics in a Current Report on Form 8-K. You may review these documents by accessing public filings at the SEC’s website at www.sec.gov.
Compensation Committee Interlocks and Insider Participation
None of our officers currently serves, or in the past year has served, as a member of the compensation committee of any entity that has one or more officers serving on our board of directors.
Compliance with Section 16(a) of the Exchange Act
Section 16(a) of the Exchange Act requires our executive officers, directors and persons who beneficially own more than 10% of a registered class of our equity securities to file with the Securities and Exchange Commission initial reports of ownership and reports of changes in ownership of our common stock and other equity securities. These executive officers, directors, and greater than 10% beneficial owners are required by SEC regulation to furnish us with copies of all Section 16(a) forms filed by such reporting persons. Based solely on our review of such forms furnished to us and written representations from certain reporting persons, we are not aware of any failure of any such person to comply with the requirements of Section 16(a) of the Exchange Act, except for the following which were not filed in a timely manner: one Form 4 filed by Hoyoung Huh.

Dr. Huh’s employment agreement, updated as of January 10, 2022, provides for Dr. Huh to serve as Peak Bio’s Chief Executive Officer (Dr. LaMond will serve as Interim Chief Executive Officer of Peak Bio while Dr. Huh is taking a leave of absence during the pendency of a personal legal proceeding). The employment agreement terms, which were subject to completion of the Business Combination, provide for Dr. Huh to receive an annual base salary and to participate in a cash bonus plan with a target of up to 65% of base salary based on annual performance standards to be established by the board of directors.

Further, the employment agreement provides for the payment of success fees in connection with future business or corporate development transactions (licensing, product development and acquisitions).

Procedures with Respect to Review and Approval of Related Person Transactions
Upon consummation of the Business Combination, our board of directors adopted a written related person transaction policy that sets forth the following policies and procedures for the review and approval or ratification of related person transactions.
A “Related Person Transaction” is a transaction, arrangement or relationship in which we or any of our subsidiaries was, is or will be a participant, the amount of which involved exceeds $120,000, and in which any related person had, has or will have a direct or indirect material interest. A “Related Person” means:
We also adopted policies and procedures designed to minimize potential conflicts of interest arising from any dealings it may have with its affiliates and to provide appropriate procedures for the disclosure of any real or potential conflicts of interest that may exist from time to time. Specifically, pursuant to our audit committee charter, the audit committee will have the responsibility to review related person transactions.
Item 14. Principal Accounting Fees and Services.
The following is a summary of fees paid or to be paid to Marcum LLP, or Marcum, the Company’s independent registered public accounting firm.
Audit Fees. Audit fees consist of fees billed for professional services rendered for the audit of our financial statements included in this Annual Report on Form 10-K, and review of financial statements included in our quarterly reports on Form 10-Q and services that are normally provided by our independent registered public accounting firm, in connection with regulatory filings and public offerings. The aggregate fees billed by Marcum for professional services rendered for the audit of our annual financial statements and other required filings with the SEC for each of the fiscal years ended December 31, 2023 and 2022 totaled $310,000 and $883,291. The above amounts include interim procedures and audit fees, as well as attendance at audit committee meetings.
Audit-Related Fees. Audit-related services consist of fees billed for assurance and related services that are reasonably related to performance of the audit or review of our financial statements and are not reported under “Audit Fees.” These services include attest services that are not required by statute or regulation and consultations concerning financial accounting and reporting standards. We did not pay Marcum for consultations concerning financial accounting and reporting standards during the years ended December 31, 2023 and 2022.
124
Tax Fees. We did not pay Marcum for tax planning and tax advice for the years ended December 31, 2023 and 2023.
All Other Fees. We did not pay Marcum for other services for the years ended December 31, 2023 and 2022.
Pre-Approval Policy
Our Audit Committee was formed upon the consummation of our Business Combination. As a result, the audit committee did not pre-approve all of the foregoing services, although any services rendered prior to the formation of our audit committee were approved by our board of directors. Since the formation of our audit committee, and on a going-forward basis, the audit committee has and will pre-approve all auditing services and permitted non-audit services to be performed for us by our auditors, including the fees and terms thereof (subject to the de minimis exceptions for non-audit services described in the Exchange Act which are approved by the audit committee prior to the completion of the audit).

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Shareholders and Board of Directors of
Peak Bio, Inc.
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Peak Bio Inc. (the “Company”) as of December 31, 2023 and 2022, the related consolidated statements of operations and comprehensive loss, deficit and cash flows for the years then ended and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America.
Explanatory Paragraph – Going Concern
The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As more fully described in Note 1, the Company has a working capital deficiency, an accumulated deficit and negative cash flows in operating activities. The Company needs to raise additional capital to meet its obligations, fund operations and continue developing its product candidates. These conditions raise substantial doubt about the Company's ability to continue as a going concern. Management's plans regarding these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that may be necessary should the Company be unable to continue as a going concern.
Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
/s/ Marcum llp
We have served as the Company’s auditor since 2022.

PEAK BIO
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Peak Bio, Inc., together with its fully-owned subsidiaries, Peak Bio Co. Ltd (“Peak Bio Ltd”) and Peak Bio CA, Inc. (the “Company” or “Peak Bio”), is a clinical-stage biotechnology company focused on discovering, developing and delivering innovative therapies for multiple therapeutic areas. The Company has established a portfolio of potential therapies focused on cancer and immunological diseases. The Company’s pipeline includes the PH-1 ADC Platform for oncology, PHP-303 program for genetic disease, liver disease and inflammation, specifically for Alpha-1 antitrypsin deficiency (AATD) and acute respiratory distress syndrome (ARDS) including COVID-19. Prior to March 1, 2022 (see below), the Company operated as pH Pharma Ltd, a Korean company.
Spin-Off
On March 1, 2022, pH Pharma Ltd completed the spin-off of certain assets and liabilities into a newly formed entity, pH Pharma Co., Ltd, except for the assets and liabilities related to PHP-303 and PH-1 ADC Platform programs, and changed its name to Peak Bio Co., Ltd. (the “Spin-Off”). The Spin-Off resulted in Peak Bio Co., Ltd. retaining
Ignyte Acquisition Corp (Ignyte)
On November 1, 2022 (the “Closing Date”), the Company completed the transactions contemplated by the certain business combination agreement, dated as of April 28, 2022 (the “Business Combination Agreement”), by and among Ignyte Acquisition Corp. (“Ignyte”), a public company, Ignyte Korea Co., Ltd., a corporation organized under the laws of the Republic of Korea (“Korean Sub”), and Peak Bio Co., Ltd (“Ignyte Business Combination”). At the closing of the Ignyte Business Combination, the stockholders of Peak Bio Ltd transferred their common stock shares to Korean Sub in exchange for shares of Ignyte common stock held by Korean Sub, which Korean Sub received in exchange for the shares of Peak Bio Ltd common stock from Ignyte (the “Share Swap”). Upon consummation of the Share Swap, Peak Bio Ltd became a direct wholly owned subsidiary of Ignyte. At the Closing Date, Ignyte changed its name to “Peak Bio, Inc.”
At the Closing Date, each common stock share of Peak Bio Ltd was converted into
At the Closing Date, a purchaser (the “Original Subscriber”) purchased from the Company an aggregate of
At the Closing Date, certain additional purchasers (each, a “New Subscriber”) purchased from the Company an aggregate of (i)
Finally, at the Closing Date, certain Peak Bio Ltd.’s lenders received from the Company an aggregate of (i)
Akari Merger Agreement
On March 4, 2024, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Akari Therapeutics, Plc, a public company limited by shares incorporated in England and Wales (“Akari”), and Pegasus Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Akari (“Merger Sub”), pursuant to which, Merger Sub will be merged with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly-owned subsidiary of Akari.
F-7
Pursuant to the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each issued and outstanding share of the Company’s Common Stock will be converted into the right to receive Akari American Depositary Shares (“Akari ADSs”) representing a number of Akari ordinary shares, par value $
At the Effective Time, each warrant and option to purchase capital stock of the Company (“Peak Warrant”) outstanding immediately prior to the Effective Time will be exchanged for a warrant or option to purchase a number of Akari ordinary shares or Akari ADSs, as determined by Akari, based on the Exchange Ratio.
To date, the Akari merger has not been consummated.
Voting Agreements
Concurrently with the Merger Agreement, the Company and Akari entered into voting and support agreements (the “Voting Agreements”) with certain stockholders of the Company (the “Peak Stockholders”) and certain shareholders of Akari (the “Akari Shareholders” and, together with the Peak Stockholders, the “Supporting Holders”). The Supporting Holders have agreed to, among other things, vote their shares in favor of the Merger Agreement and the Merger or the issuance of Akari Ordinary Shares in connection therewith, as applicable, in accordance with the recommendation of the respective boards of directors of Peak Bio and Akari.
Risks and Uncertainties
The Company is subject to a number of risks similar to other companies in its industry, including competition from larger pharmaceutical and biotechnology companies, delays in research and development activities due to lack of financial resources and dependence on key personnel.
Results of operations may be adversely affected by various factors that could cause economic uncertainty and volatility in the financial markets, many of which are beyond the Company’s control. The Company’s business could be impacted by, among other things, downturns in the financial markets or in economic conditions, inflation, increases in interest rates, and geopolitical instability, such as the military conflicts in Ukraine and the Israel-Hamas war. While the Company has not been impacted by the abovementioned risks and uncertainties to date, the Company cannot at this time fully predict the likelihood of one or more of the above events, their duration or magnitude or the extent to which they may negatively impact the Company’s business.
Going Concern
The Company incurred significant net losses since inception, including net losses of $
The Company will need additional financing to fund its ongoing activities and to close the Merger with Akari. The Company may raise this additional funding through the sale of equity, debt financings or other capital sources, including potential collaborations with other companies or other strategic transactions and funding under government contracts.
On November 1, 2022, the Company received written notice (the “Notice”) from the Staff of the Listing Qualifications Department (the “Staff”) of the Nasdaq Stock Market LLC (“Nasdaq”) stating that the Staff determined that the Company had not complied with the listing requirements because (i) the Company had not demonstrated that its common stock complied with the minimum
On January 6, 2023, the Company received the determination letter (the “Determination Letter”) from the Panel to delist the Company’s common stock and warrants from Nasdaq. Nasdaq suspended trading in Company’s common stock and warrants effective
F-8
at the open of business on January 10, 2023. Upon suspension from Nasdaq, the Company’s securities began trading on the OTC Markets’ “OTC Pink Market” tier.
The Company may be unable to raise additional funds or enter into other arrangements when needed on favorable terms, or at all. There can be no assurances that other sources of financing will be available. Due to these uncertainties, there is substantial doubt about the Company’s ability to continue as a going concern.
The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. The consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or classification of liabilities that might result from the outcome of the uncertainties discussed above.
Basis of Presentation
The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and pursuant to the rules and regulations of the SEC. All intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates
The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates include but are not limited to fair value of the Company's stock, stock-based compensation expense, warrant liability, derivative liability, and discount rates used to establish operating lease liability. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Actual results could differ from those estimates.
Basis of Presentation Prior to Spin-Off
The financial results prior to the Spin-Off, were extracted from the accounting records of pH Pharma Ltd. on a carve-out basis. The historical results of operations, financial position, and cash flows may not be indicative of what such results of operations, financial position, and cash flows would have been had the Company been a separate standalone entity, nor are they indicative of what the results of operations, financial position and cash flows may be in the future.
The carve-out financial position and results reflect assets, liabilities, revenue, and expenses that are directly attributable to the Company, including the assets, liabilities, revenue and expenses of the PHP-303 and PH-1 ADC Platform programs. The majority of the Company’s operating expenses related to research and development (“R&D”). R&D expenses directly related to the Company were entirely attributed to the Company in the carve-out consolidated financial statements. R&D salaries, wages and benefits were allocated to the Company using methodologies based on the proportionate share of R&D expenses for the PHP-303 and PH-1 ADC Platform programs compared to the R&D expenses for pH Pharma Ltd as a whole prior to the Spin-Off. The Company was also receiving services and support from other functions of pH Pharma Ltd. The Company’s operations were dependent upon the ability of these other functions to provide these services and support. The costs associated with these services and support were allocated to the Company using methodologies based on the proportionate share of R&D expenses for the PHP-303 and PH-1 ADC Platform programs compared to the total R&D expenses and certain administrative expenses for pH Pharma Ltd as a whole. These allocated costs were primarily related to corporate administrative expenses, non-R&D employee related costs, including salaries and other benefits, for corporate and shared employees, and other expenses for shared assets for the following functional groups: information technology, legal, accounting and finance, human resources, facilities, and other corporate and infrastructural services. These allocated costs were primarily recorded as R&D expenses and general and administrative (“G&A”) expenses in the statements of operations and comprehensive loss.
The assets and liabilities excluded from the accompanying carve-out consolidated financial statements consist of:
F-9
The Company believes the assumptions and allocations underlying the carve-out financial statements were reasonable and appropriate under the circumstances.
The following activity was extracted from the accounting records of pH Pharma Ltd. on a carve-out basis for the period from January 1, 2022 to March 1, 2022:

Accounting for Ignyte Business Combination
The Ignyte Business Combination was accounted for as a reverse recapitalization in accordance with U.S. GAAP. Under this method of accounting, Ignyte is treated as the “acquired” company and Peak Bio Ltd is treated as the acquirer for financial reporting purposes. Accordingly, for accounting purposes, the Business Combination was treated as the equivalent of Peak Bio Ltd issuing stock for the net assets of Ignyte, accompanied by a recapitalization. The net assets of Ignyte were stated at historical cost, with no goodwill or other intangible assets recorded. Peak Bio Ltd was determined to be the accounting acquirer based on the following predominant factors:
The consolidated assets, liabilities and results of operations prior to the Ignyte Business Combination are those of Peak Bio Ltd. At the closing date, and subject to the terms and conditions of the Business Combination Agreement, each share of Peak Bio Ltd.'s common stock, par value $

Segment Information
Operating and reportable segments (referred to as “segments”) reflect the way the Company is managed and for which separate financial information is available and evaluated regularly by the Company’s chief operating decision maker (“CODM”) in deciding how to allocate resources and assess performance. Our chief executive officer, who is our CODM, views the Company’s operations and manages its business in one operating segment, focused on the discovery and development of innovative therapies for multiple therapeutic areas.
Fair Value Measurements
The Company records certain liability balances under the fair value measurements as defined by the FASB guidance. Current FASB fair value guidance emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, current FASB guidance establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions that market participants would use in pricing assets or liabilities (unobservable inputs classified within Level 3 of the hierarchy).
Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at measurement date.
Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals.
Level 3 inputs are unobservable inputs for the asset or liability, which is typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs
F-11
from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.

Currency and currency translation
The consolidated financial statements are presented in U.S. dollars, the Company’s reporting currency. The functional currency of Peak Bio CA, Inc. is the U.S. dollar. The functional currency of Peak Bio Co., Ltd is the Korean Won. Adjustments that arise from exchange rate changes on transactions of each group entity denominated in a currency other than the functional currency are included in other income and expense in the consolidated statements of operations. Assets and liabilities of Peak Bio Co., Ltd are recorded in their Korean Won functional currency and translated into the U.S. dollar reporting currency of the Company at the exchange rate on the balance sheet date. Revenue, when recorded, and expenses of Peak Bio Co., Ltd are recorded in their Korean Won functional currency and translated into the U.S. dollar reporting currency of the Company at the average exchange rate prevailing during the reporting period. Resulting translation adjustments are recorded to other comprehensive income (loss).
Concentration of credit risk
The Company maintains its cash balances in the form of business checking accounts and money market accounts in the U.S., the balances of which, at times, may exceed federally insured limits. The Federal Deposit Insurance Corporation (“FDIC”) insurance coverage limit is $
Prepaid expenses and Other Current Assets
Prepaid expenses and other current assets includes other receivables. Other receivables are presented net of an allowance for credit losses, which is an estimate of amounts that may not be collectible. The Company performs ongoing credit evaluations of its counter parties and monitors economic conditions to identify facts and circumstances that may indicate its receivables are at risk of collection.
Property and Equipment
Property and equipment are stated at cost, less accumulated depreciation. Depreciation is calculated over the estimated useful lives of the respective assets, which range from two to five years, or the lesser of the related initial term of the lease or useful life for leasehold improvements.
The initial cost of property and equipment consists of its purchase price and any directly attributable costs of bringing the asset to its working condition and location for its intended use. Expenditures incurred after the assets have been put into operation, such as repairs and maintenance, are charged to expense in the period in which the costs are incurred. Major replacements, improvements, and additions are capitalized in accordance with Company policy.
Impairment of Long-lived Assets
Long-lived assets consist primarily of property and equipment, and operating right-of-use assets. The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset is not recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the asset exceeds the fair value of the assets. Fair value would be assessed using discounted cash flows or other appropriate measures of fair value. The Company recognized an impairment loss on its operating right-of-use assets, totaling $
F-12
Derivative Instruments
The Company issued warrants to its investors and accounts for warrant instruments as either equity-classified or liability-classified instruments based on an assessment of the specific terms of the warrants and applicable authoritative guidance in ASC 480 and ASC 815, “Derivatives and Hedging” (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, “Distinguishing Liabilities from Equity” (“ASC 480”), meet the definition of a liability pursuant to ASC 480, and meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own stock and whether the holders of the warrants could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification.
The Key Company Stockholder Forward Purchase Liability entered into on April 28, 2022 resulted in the Company holding a put option on shares to be purchased. The Forward Share Purchase Agreement entered into on October 22, 2022 resulted in the Company holding a put option on shares to be purchased. The White Lion Purchase Agreement includes an embedded put option and an embedded forward option (see Note 11). Pursuant to ASC 815, these instruments meet the definition of a derivative and accordingly were recognized at fair value and are remeasured at fair value at each period end.
Grant Revenue
The Company’s grant revenues are derived from research programs with the Department of Defense, US Army Medical Research Acquisition Activity for work on a COVID-19 therapeutic.
Grants awarded to the Company for research and development by government entities are outside the scope of the contracts with customers and contributions guidance. This is because these granting entities are not considered to be customers and are not receiving reciprocal value for their grant support provided to the Company. These grants provide the Company with payments for certain types of expenditures in return for research and development activities over a contractually defined period.
The Company recognizes grant revenue based on the reimbursable costs that are incurred due the period, up to pre-approved award limits. The expenses associated with these reimbursements are reflected as a component of research and development expense in the accompanying consolidated statements of operations and comprehensive loss. For the years ended December 31, 2023 and 2022, the Company recognized grant revenue of approximately $
Research and Development Expenses
Research and development costs are expensed as incurred. Research and development expenses consist primarily of costs related to personnel, including salaries and other personnel related expenses, contract manufacturing and supply, consulting fees, and the cost of facilities and support services used in drug development. Assets acquired that are used for research and development and have no future alternative use are expensed as in-process research and development.
General and Administrative Costs
General and administrative expenses consist primarily of salaries and related benefits, including stock-based compensation, related to our executive, finance, business development, legal, human resources and support functions. Other general and administrative expenses include professional fees for auditing, tax, consulting and patent-related services, rent and utilities and insurance.
Share-based Compensation
The Company accounts for stock option awards in accordance with ASC 718, Compensation-Stock Compensation (“ASC 718”). The estimated grant date fair value of the stock option awards are recognized as compensation expense over the requisite service period of the awards (usually the vesting period) on a straight-line basis The Company estimates the fair value of each stock-based award on the date of grant using the Black-Scholes option pricing model. The Black-Scholes option pricing model incorporates various assumptions, such as the value of the underlying common stock, the risk-free interest rate, expected volatility, expected dividend yield, and expected life of the options. Expected volatility is based on the historical volatility of a publicly traded set of peer companies. The Company’s historical share option exercise experience does not provide a reasonable basis upon which to estimate an expected term because of a lack of sufficient data. Therefore, the Company estimates the expected term by using the simplified method, which calculates the expected term as the average of the time-to-vesting and the contractual life of the options. The risk-free interest rate is based on U.S. Treasury, zero-coupon issues with a remaining term equal to the expected life assumed at the date of grant (or modification, as applicable). Equity-based compensation expense is classified in the statements of operations in the same
F-13
manner in which the award recipients’ payroll costs or service payments are classified. Forfeitures are recognized as a reduction of stock-based compensation expense as they occur.

Net Loss Per Share
The Company computes basic net loss per share attributable to common stockholders by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period, without consideration for potentially dilutive securities.
The Company computes diluted net loss per share after giving consideration to all potentially dilutive common shares resulting from the exercise of options and warrants and the conversion of convertible notes, outstanding during the period determined using the treasury-stock and if-converted methods, as applicable, except where the effect of including such securities would be antidilutive.
The December 2023 Convertible Notes (see Note 10) are contingently convertible notes and are not included for purposes of calculating the number of diluted shares outstanding as the number of dilutive shares is based on a non-market based conversion contingency that had not been met, and the contingency was not resolved, in the reporting periods presented herein.
For all periods presented, there is no difference in the number of shares used to calculate basic and diluted shares outstanding as inclusion of the potentially dilutive securities would be antidilutive.
The following table sets forth the potentially dilutive securities that have been excluded from the calculation of diluted net loss per share because to include them would be anti-dilutive (in common stock equivalent shares):

Income Taxes
F-14
Deferred income taxes reflect future tax effects of temporary differences between the tax and financial reporting basis of the Company’s assets and liabilities measured using enacted tax laws and statutory tax rates applicable to the periods when the temporary differences will affect taxable income. When necessary, deferred tax assets are reduced by a valuation allowance, to reflect realizable value, and all deferred tax balances are reported as long-term on the balance sheet. Accruals are maintained for uncertain tax positions, as necessary.
The Company uses a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken, or expected to be taken, in a tax return. The Company has elected to treat interest and penalties related to income taxes, to the extent they arise, as a component of income taxes.
The Company recognizes the tax benefits of uncertain tax positions only when the positions are “more likely than not” to be sustained assuming examination by tax authorities and determined to be attributed to the Company. The determination of attribution, if any, applies for each jurisdiction where the Company is subject to income taxes on the basis of laws and regulations of the jurisdiction. The application of laws and regulations is subject to legal and factual interpretation, judgment, and uncertainty. Tax laws and regulations themselves are subject to change as a result of changes in fiscal policy, changes in legislation, the evolution of regulations, and court rulings. Therefore, the actual liability of the various jurisdictions may be materially different from management’s estimate. As of December 31, 2023, and 2022 the Company has not recorded any amounts related to uncertain tax positions. The Company has no accruals for interest or penalties related to income tax matters. Tax years subsequent to 2020 remain open to examination by federal and state tax authorities.
Leases
The Company accounts for leases in accordance with ASC Topic 842, Leases (“ASC 842”). The Company determines the initial classification and measurement of its right-of-use assets and lease liabilities at the lease commencement date and, if modified, on the date of modification. The lease term includes any renewal options and termination options that the Company is reasonably certain to exercise. The present value of lease payments is determined by using the incremental borrowing rate determined by using the rate of interest that the Company would pay to borrow on a collateralized basis an amount equal to the lease payments for a similar term and in a similar economic environment.
Rent expense is recognized on a straight-line basis, over the reasonably assured lease term based on total lease payments and is included in operating expenses in the consolidated statements of operations and comprehensive loss.
The Company has elected the practical expedient to not separate lease and non-lease components. The Company has also elected not to record on the consolidated balance sheets a lease for which the term is 12 months or less and does not include a purchase option that the Company is reasonably certain to exercise.
Recently Adopted Accounting Standards
In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 requires measurement and recognition of expected credit losses for financial assets. In April 2019, the FASB issued clarification to ASU 2016-13 within ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, or ASU 2016-13. The guidance is effective for fiscal years beginning after December 15, 2022. The adoption of ASU No. 2016-13 on January 1, 2023 did not have a material effect on the Company's consolidated financial statements.
Recently Issued Accounting Standards
In August 2020, the FASB issued ASU 2020-06, “Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity” (“ASU 2020-06”), which simplifies the accounting for convertible instruments by removing major separation models required under current U.S. GAAP. ASU 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, which will permit more equity contracts to qualify for such exception and simplifies the diluted earnings per share calculation in certain areas. ASU 2020-06 is effective for public business entities that meet the definition of a SEC filer, excluding entities eligible to be smaller reporting companies as defined by the SEC, for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company adopted ASU 2020-06 on January 1, 2024 and the adoption did not have a material effect on the Company’s consolidated financial statements.
F-15
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which includes amendments that further enhance income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. The amendments are effective for all public entities for fiscal years beginning after December 15, 2024. Early adoption is permitted and should be applied either prospectively or retrospectively. The Company plans to adopt ASU 2023-09 and related updates on January 1, 2025. The Company is currently evaluating the impact that the updated standard will have on its financial statement disclosures.
In November 2023, the FASB issued ASU 2023-07, Segment Reporting: Improvements to Reportable Segment Disclosures. This ASU modified the disclosure and presentation requirements primarily through enhanced disclosures of significant segment expenses and clarified that single reportable segment entities must apply Topic 280 in its entirety. This guidance is effective for the Company for the year beginning January 1, 2024, with early adoption permitted. The amendments should be applied retrospectively to all prior periods presented in the financial statement. The Company adopted ASU 2023-07 on January 1, 2024 and the adoption did not have a material effect on the Company’s consolidated financial statements.

Deferred income taxes reflect future tax effects of temporary differences between the tax and financial reporting basis of the Corporation’s assets and liabilities measured using enacted tax laws and statutory tax rates applicable to the periods when the temporary differences will affect taxable income. When necessary, deferred tax assets are reduced by a valuation allowance, if based on the weight of available positive and negative evidence, it is more likely than not that some portion or all the deferred tax assets will not be realized.

Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, or the Code, if a corporation undergoes an "ownership change," the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes to offset its post-change income and taxes may be limited. In general, an "ownership change" generally occurs if there is a cumulative change in the Company’s ownership by "5-percent shareholders" that exceeds 50 percentage points over a rolling three-year period.

As of December 31, 2023, we have not provided taxes on undistributed earnings of our foreign subsidiaries, which may be subject to foreign withholding taxes upon repatriation, as we consider these earnings indefinitely reinvested. Our indefinite reinvestment determination is based on the future operational and capital requirements of our domestic and foreign operations. We expect our international cash and cash equivalents and marketable securities will continue to be used for our foreign operations and therefore do not anticipate repatriating these funds. As of December 31, 2023, it is not practical to calculate the unrecognized deferred tax liability on these earnings due to the complexities of the utilization of foreign tax credits and other tax assets.
