Panbela Therapeutics, Inc.
Notes to Condensed Consolidated Financial Statements

1. Business

Panbela Therapeutics, Inc. and its wholly-owned subsidiary Panbela Therapeutics Pty Ltd (collectively “we,” “us,” “our,” and the “Company”) exist for the primary purpose of advancing the commercial development of a proprietary polyamine analogue for the treatment of patients with pancreatic cancer. We have exclusively licensed the worldwide rights to this compound, which has been designated as SBP-101, from the University of Florida Research Foundation, Inc. (“UFRF”).

2. Risks and Uncertainties

The Company operates in a highly regulated and competitive environment. The development, manufacturing and marketing of pharmaceutical products require approval from, and are subject to ongoing oversight by, the Food and Drug Administration (“FDA”) in the United States, the Therapeutic Goods Administration in Australia, the European Medicines Agency in the European Union, and comparable agencies in other countries. Obtaining approval for a new pharmaceutical product is never certain, may take many years, and is normally expected to involve substantial expenditures.

We have incurred losses of $52.6 million since our inception in 2011. For the nine months ended September 30, 2021, we incurred a net loss of $6.6 million. We also incurred negative cash flows from operating activities of approximately $5.0 million for this period. As we continue to pursue development activities and seek commercialization of our initial product candidate, SBP-101, we expect to incur substantial losses, which are likely to generate negative net cash flows from operating activities. As of September 30, 2021, we had cash and cash equivalents of $14.1 million, working capital of $13.4 million, (current assets less current liabilities) and stockholders’ equity of $13.5 million. The Company’s principal sources of cash have historically included the issuance of convertible debt and equity securities.

The accompanying condensed consolidated financial statements have been prepared assuming that we will continue as a going concern, which contemplates the realization of assets and liquidation of liabilities in the normal course of business. The condensed consolidated financial statements do not include any adjustments relating to the recoverability or classification of assets or the amounts of liabilities that might result from the outcome of these uncertainties. Our current independent registered public accounting firm included a paragraph emphasizing this going concern uncertainty in their audit report regarding our 2020 financial statements dated March 25, 2021. Our ability to continue as a going concern, realize the carrying value of our assets and discharge our liabilities in the ordinary course of business is dependent upon a number of factors, including our ability to obtain additional financing, the success of our development efforts, our ability to obtain marketing approval for our SBP-101 product candidate in the United States, Australia, the European Union or other markets and ultimately our ability to market and sell our SBP-101 product candidate. These factors, among others, raise substantial doubt about our ability to continue operations as a going concern. See Note 4 titled “Liquidity and Business Plan.”

September 2021 marked 18 months since the World Health Organization declared the spread of a novel strain of coronavirus (“COVID-19”) a global pandemic. Early in the pandemic, actions were taken by federal, state and local governmental authorities to combat the spread of COVID-19, including through issuances of “stay-at-home” directives and similar mandates for many individuals to substantially restrict daily activities and for many businesses to curtail or cease normal operations. These measures, while intended to protect human life, led to significantly reduced economic activity. Vaccines became available at the end of 2020 and distribution in the U.S. accelerated during the first quarter of 2021 and then leveled off in the second quarter. Most state and local authorities have reopened businesses and while for much of the quarter ended September 30, 2021 infection rates increased in the United States and other parts of the world as the result of the delta variant, infection rates are once again decreasing. The rapid development and uncertainty of the situation continues to preclude any prediction as to the ultimate impact COVID-19 will have on the Company's business, financial condition, results of operation and cash flows, which will depend largely on future developments directly or indirectly relating to the duration and scope of the COVID-19 outbreak in the United States, Australia and the rest of the world. During the spring of 2020 enrollment in our clinical trial was temporarily paused to allow our clinical sites time to prepare for COVID -19. No disruption occurred as a result of COVID -19 to the treatment of subjects enrolled prior to or after this pause in the study and the study enrollment was completed in December of 2020. During the spring of 2021, the Company also experienced a delay in the manufacturing of the active product ingredient, which is manufactured in India. There was no disruption in supply for our clinical or preclinical testing. The active ingredient for our next clinical trial has now been received in the United States. The Company’s administrative operations have been decentralized since inception so the Company experienced no administrative disruptions or additional costs due to the pandemic or related restrictions.

3. Basis of Presentation

We have prepared the accompanying interim condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Regulation S-X of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These interim condensed consolidated financial statements reflect all adjustments consisting of normal recurring accruals, which, in the opinion of management, are necessary to present fairly our consolidated financial position, consolidated results of operations and consolidated cash flows for the periods and as of the dates presented. Our fiscal year ends on December 31. The condensed consolidated balance sheet as of December 31, 2020, was derived from audited consolidated financial statements but does not include all disclosures required by U.S. GAAP. These interim condensed consolidated financial statements should be read in conjunction with the annual consolidated financial statements and the notes thereto included in our most recent filed Annual Report on Form 10-K and our subsequent filings with the SEC. The nature of our business is such that the results of any interim period may not be indicative of the results to be expected for the entire year.

4. Liquidity and Business Plan

On July 2, 2021, the Company completed an underwritten public offering of 3,333,334 shares of common stock at $3.00 per share which resulted in net proceeds of approximately $9.1 million.

Between February 5 and March 23, 2021, the Company issued 228,938 shares of common stock as the result of the exercise of outstanding warrants. Total cash received was approximately $1.0 million.

On September 1, 2020, the Company completed an underwritten public offering of 2,545,454 shares of common stock and warrants to purchase the same number of shares of common stock which resulted in net proceeds of approximately $9.3 million. In addition to the underwritten offering, the Company sold common stock and warrants to purchase common stock in private placements to certain accredited investors during the nine months ended September 30, 2020 resulting in net proceeds of approximately $1.7 million.

We will need to raise additional capital to fully fund the randomized clinical trial set to begin enrollment at the end of 2021.Our future success is dependent upon our ability to obtain additional financing, the success of our development efforts, our ability to obtain marketing approval for our SBP-101 product candidate in the United States or other markets and ultimately our ability to market and sell our SBP-101 product candidate. If we are unable to obtain additional financing when needed, if our clinical trials are not successful or if we are unable to obtain marketing approval, we would not be able to continue as a going concern and would be forced to cease operations and liquidate the Company.

There can be no assurances that we will be able to obtain additional financing on commercially reasonable terms, or at all. The sale of additional convertible debt or equity securities would likely result in dilution to our current stockholders.

5. Summary of Significant Accounting Policies

Principles of consolidation

The accompanying condensed consolidated financial statements include the assets, liabilities, and expenses of the Company. All significant intercompany transactions and balances have been eliminated in consolidation.

8

Use of estimates

The preparation of condensed consolidated financial statements 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 condensed consolidated financial statements and the reported amount of expenses during the reporting period. Actual results could differ from those estimates, particularly given the significant social and economic disruptions and uncertainties with the ongoing pandemic and control responses.

Research and development costs

Research and development costs include expenses incurred in the conduct of our second Phase 1 human clinical trial, for third-party service providers performing various testing and accumulating data related to our preclinical studies; sponsored research agreements; developing and scaling the manufacturing process necessary to produce sufficient amounts of the SBP-101 compound for use in our pre-clinical studies and human clinical trials; consulting resources with specialized expertise related to execution of our development plan for our SBP-101 product candidate; personnel costs, including salaries, benefits and share-based compensation; and costs to license and maintain our licensed intellectual property.

We charge research and development costs, including clinical trial costs, to expense when incurred. Our human clinical trials are, and will be, performed at clinical trial sites and are administered jointly by us with assistance from contract research organizations (“CROs”). Costs of setting up clinical trial sites are accrued upon execution of the study agreement. Expenses related to the performance of clinical trials generally are accrued based on contracted amounts and the achievement of agreed upon milestones, such as patient enrollment, patient follow-up, etc. We monitor levels of performance under each significant contract, including the extent of patient enrollment and other activities through communications with the clinical trial sites and CROs, and adjust the estimates, if required, on a quarterly basis so that clinical expenses reflect the actual effort expended at each clinical trial site and by each CRO.

All material CRO contracts are terminable by us upon written notice and we are generally only liable for actual effort expended by the CROs and certain non-cancelable expenses incurred at any point of termination.

We expense costs associated with obtaining licenses for patented technologies when it is determined there is no alternative future use of the intellectual property subject to the license.

Stock-based compensation

In accounting for stock-based incentive awards, we measure and recognize the cost of employee and non-employee services received in exchange for awards of equity instruments based on the fair value of those awards on the grant date. Calculating stock-based compensation expense requires the input of highly subjective assumptions, which represent our best estimates and involve inherent uncertainties and the application of management’s judgment. Compensation cost is recognized ratably using the straight-line attribution method over the vesting period, which is considered to be the requisite service period. Compensation expense for performance-based stock option awards is recognized when “performance” has occurred or is probable of occurring.

The fair value of stock-based awards is estimated at the date of grant using the Black-Scholes option pricing model. The determination of the fair value of stock-based awards is affected by our stock price, as well as assumptions regarding a number of complex and subjective variables. Risk free interest rates are based upon U.S. Treasury rates appropriate for the expected term of each award. Expected volatility rates are based primarily on the volatility rates of a set of guideline companies, which consist of public and recently public biotechnology companies. The assumed dividend yield is zero, as we do not expect to declare any dividends in the foreseeable future. The expected term of options granted is determined using the “simplified” method. Under this approach, the expected term is presumed to be the mid-point between the average vesting date and the end of the contractual term.

Foreign currency translation adjustments

The functional currency of Panbela Therapeutics Pty Ltd is the Australian Dollar. Accordingly, assets and liabilities, and equity transactions of Panbela Therapeutics Australia Pty Ltd are translated into U.S. dollars at period-end exchange rates. Revenues and expenses are translated at the average exchange rate in effect for the period. The resulting translation gains and losses are recorded as a component of accumulated comprehensive loss presented within the stockholders’ equity. During the three and nine-month periods ended September 30, 2021, and 2020, any reclassification adjustments from accumulated other comprehensive loss to operations were inconsequential.

9

Comprehensive loss

Comprehensive loss consists of our net loss and the effects of foreign currency translation.

Net loss per share

Basic net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding during the period. Diluted net loss per share is based on the weighted average of common shares outstanding during the period plus dilutive potential common shares calculated using the treasury stock method. Such potentially dilutive shares are excluded when the effect would be anti-dilutive or reduce a net loss per share. The Company’s potential dilutive shares, which include outstanding common stock options, and warrants, have not been included in the computation of diluted net loss per share for all periods as the result would be anti-dilutive.

The following table sets forth the potential shares of common stock that were not included in the calculation of diluted net loss per share as their effects would have been anti-dilutive as of the dates indicated:

	September 30,
	2021		2020
Employee and non-employee stock options		2,489,136		2,170,459
Resticted stock units		16,185		-

2016 Omnibus Incentive Plan

The Panbela Therapeutics, Inc. 2016 Omnibus Incentive Plan (the “2016 Plan”) was adopted by our Board of Directors in March 2016 and approved by our stockholders in May 2016. The 2016 Plan permits the granting of incentive and non-statutory stock options, restricted stock, stock appreciation rights, performance units, performance shares and other stock awards to eligible employees, directors and consultants. We grant options to purchase shares of common stock under the 2016 Plan at no less than the fair market value of the underlying common stock as of the date of grant. Options granted under the 2016 Plan have a maximum term of ten years. As of September 30, 2021, options to purchase 2,257,136 shares of common stock and 16,185 restricted stock units, each representing the right to receive one share of common stock, were outstanding under the 2016 Plan and 1,328,363 shares remained available for future awards.

2011 Stock Option Plan

Our Board of Directors ceased making awards under the Panbela Therapeutics, Inc. 2011 Stock Option Plan (the “2011 Plan”) upon the original receipt of stockholder approval for the 2016 Plan in May 2016. Awards outstanding under the 2011 Plan remain outstanding in accordance with and pursuant to the terms thereof. As of September 30, 2021, options to purchase 232,000 shares of common stock remained outstanding under the 2011 Plan. The average remaining life is approximately 3.2 years.

Stock-based Compensation Expense

General and administrative (“G&A”) and research and development (“R&D”) expenses include non-cash stock-based compensation expense as a result of our issuance of stock options. The terms and vesting schedules for stock-based awards vary by type of grant and the employment status of the grantee. The awards granted through September 30, 2021, vest based upon time-based and performance conditions. There was approximately $1.9 million unamortized stock-based compensation expense related to options granted to employees as of September 30, 2021.

Overview

We exist for the primary purpose of advancing the commercial development of our proprietary polyamine analogue in solid tumors with an initial focus on pancreatic cancer.

We have exclusively licensed the worldwide rights to this compound, which has been designated as SBP-101, from the UFRF.

In August 2015, the FDA accepted our Investigational New Drug (“IND”) application for our SBP-101 product candidate.

In 2017 we completed an initial clinical trial of SBP-101 in patients with previously treated locally advanced or metastatic pancreatic cancer. This was a Phase 1, first-in-human, dose-escalation, monotherapy safety study. From January 2016 through September 2017, we enrolled twenty-nine patients into six cohorts (cohorts 5a and 5b while the same dose, were separated as the result of different manufacturing lots) in the dose-escalation phase of the Phase 1 trial. No drug-related bone marrow toxicity or peripheral neuropathy was observed at any dose level. In addition to being evaluated for safety, 23 of the 29 patients were evaluable for preliminary signals of efficacy prior to or at the eight-week conclusion of their first cycle of treatment using the Response Evaluation Criteria in Solid Tumors (“RECIST”), the currently accepted standard for evaluating change in the size of tumors. Eight of the 23 patients (35%) had stable disease (“SD”) and 15 of 24 (65%) had progressive disease (“PD”). It should be noted that of the 15 patients with PD, six came from cohorts one and two and are considered to have received less than potentially therapeutic doses of SBP-101. We also noted that 28 of the 29 patients had follow-up blood tests measuring the Tumor Marker CA 19-9 associated with pancreatic ductal adenocarcinoma. Eleven of these patients (39%) had reductions in the CA 19-9 levels, as measured at least once after the baseline assessment. Seven of the remaining 17 patients who showed no reduction in CA 19-9 came from cohorts one and two.

In December of 2020 we completed enrollment of patients in our second clinical trial, a Phase 1a/1b study of the safety, efficacy and pharmacokinetics of SBP-101 administered in combination with two standard-of-care chemotherapy agents, gemcitabine and nab-paclitaxel. A total of 25 subjects were enrolled in 4 cohorts in the Phase 1a portion of the trial to evaluate the dosage level and schedule. An additional 25 subjects were enrolled in the expansion or Phase 1b portion of the trial. On June 4, 2021, we announced the presentation of interim clinical data from our Phase 1 combination therapy study, “SBP-101, a polyamine metabolic inhibitor, administered in combination with gemcitabine and nab-paclitaxel (“G+A”), shows signals of efficacy as first-line treatment for subjects with metastatic pancreatic ductal adenocarcinoma (“PDA”),” at the American Society of Clinical Oncology (“ASCO”) Annual Meeting held June 4-8, 2021. 

SBP-101 was well-tolerated when administered at doses and schedules tested in combination with G+A in subjects with previously untreated metastatic PDA. The most common Grade ≥3 adverse events (“AEs”) related to any study medication were neutropenia in 20 subjects (19 attributed to G+A and 1 attributed to all 3) and elevated liver function tests (“LFTs”) in 15 subjects (5 attributed to SBP-101 and 10 attributed to all 3). SBP-101-related increases in LFTs were asymptomatic in all but 2 subjects and reversed in all but 1 subject when SBP-101 administration was interrupted and dose-reduced or discontinued. Six subjects experienced vision AEs (3 possibly related to SBP-101, 1 related to gemcitabine and 2 related to all 3 based on principal investigator assessment. All were considered by the sponsor to be possibly related to SBP-101; 5 subjects had findings consistent with retinopathy. Future studies will exclude patients with a history of retinopathy or at risk of retinal detachment and scheduled ophthalmologic monitoring for all patients. Additionally, in future dose-finding studies screening for retinal toxicity will be included.

Interim efficacy was reported for 29 response-evaluable subjects in Cohort 4 + Phase 1b as well as for 7 subjects in Cohort 2.  Eleven subjects in Cohort 4 + Phase 1b had treatment with SBP-101 interrupted to evaluate retinal toxicity. The dose level in Cohort 4 + Phase 1b was the same as Cohort 2; however, the dose schedule was altered. The dose interruption may confound final efficacy results for Cohort 4 + Phase 1b. In Cohort 2 (N=7), the objective response rate (“ORR”) was 71%, and the disease control rate (“DCR”) was 100% by RECIST criteria (SD or better for ≥ 16 weeks). Median progression free survival (“PFS”) in Cohort 2 was 5.6 months and median overall survival (“OS”) was 10.3 months. In Cohort 4 + Phase 1b (N=29), the ORR was 48%, DCR was 70%, and PFS was 5.2 months; median OS has not been reached in Cohort 4 + Phase 1b to date. Subsequent to the release of this data in our poster at ASCO, one subject with a partial response converted to a complete response (“CR”) and one subject while non-CR by RECIST criteria had no evidence of disease.

13

The Company believes that the interim results of the front-line clinical trial of our SBP-101 product candidate justify continued development. Additional clinical trials will be required for FDA or other country approvals. We expect to begin a randomized clinical trial of SBP-101 administered in combination with two standard-of-care chemotherapy agents, gemcitabine and nab-paclitaxel for first line treatment of metastatic PDA by the end of 2021. The cost and expected duration of this randomized clinical trial is highly dependent on the nature and size of the trial which is still being finalized at this time.

We are also exploring SBP-101 for neo-adjuvant treatment in appropriate patients. There is also preclinical data to suggest that SBP-101 may have potential therapeutic uses for cancers other than pancreatic. In February 2021, we entered into a research agreement with the Johns Hopkins University School of Medicine. The collaboration is intended to focus on the further development of Panbela’s investigative agent SBP-101, including activity in cell lines outside of pancreatic cancer, biomarkers informing diagnostics and potential combination with checkpoint inhibitors. We expect these efforts will yield preclinical data to inform future development by the end of this calendar year.

Financial Overview

We have incurred losses of $52.6 million since 2011. For the nine months ended September 30, 2021, we incurred a net loss of $6.6 million. We also incurred negative cash flows from operating activities of approximately $5.0 million for this period. We expect to continue to incur substantial losses, which will generate negative net cash flows from operating activities, as we continue to pursue research and development activities and commercialize our SBP-101 product candidate.

Our cash was approximately $14.1 million and $9.0 million as of September 30, 2021 and December 31, 2020, respectively.

An increase of $5.0 million in cash for the nine months ended September 30, 2021 was due to negative cash flow from operations of approximately $5.0 million offset by funds generated from the sale of common stock and the exercise of warrants during the same nine months.

Other than the temporary pause in enrollment during April and May of 2020 in our current clinical trial, the Company has not experienced any significant disruptions to our operations as a result of the COVID-19 pandemic. Recruitment and enrollment were resumed in May of 2020 and completed in December of 2020. The Company was not required to change management practices as it was decentralized prior to the COVID-19 pandemic.

We will need to obtain additional funds to continue our operations and execute our current business plans, including completing required future trials and pursuing regulatory approvals in the United States, the European Union and other international markets, and laboratory studies to explore potential indications in other cancer types. We historically have financed our operations principally from the sale of equity securities and debt. While we have been successful in the past in obtaining the necessary capital to support our operations, and have similar future plans to obtain additional financing, there is no assurance that we will be able to obtain additional financing under commercially reasonable terms and conditions, or at all. This risk would increase if our clinical data were inconclusive or not positive or economic conditions worsen in the market as a whole or in the pharmaceutical or biotechnology markets individually.

Net Loss	$	(2,142	)	$	(1,671	)		28.2	%	$	(6,597	)	$	(3,888	)		69.7	%

General and administrative (“G&A”) expenses consist primarily of salaries, incentive compensation and other employee benefits, including stock-based compensation. Other G&A expenses include professional fees for accounting and tax, legal services, insurance, and costs associated with being a publicly traded company including directors and officer’s liability insurance premiums.

Research and development (“R&D”) expenses consist primarily of clinical and regulatory costs, costs incurred under agreements with contract research organizations, pre commercial manufacturing and stability testing and employee compensation related expenses.

R&D and G&A expenses include non-cash stock-based compensation expense because of our issuances of stock options. We expense the fair value of equity awards over their vesting periods. The terms and vesting schedules for share-based awards vary by type of grant and the employment status of the grantee. The awards granted through September 30, 2020 vest upon performance and time-based conditions. We expect to record additional non-cash share-based compensation expense in the future, which may be significant.

The following table summarizes the stock-based compensation expense in our statements of comprehensive loss for:

	Nine Months Ended September 30
	2021		2020
General and administative	$	798	$	860
Research and Development		153		109
Total Stock based compensation	$	951	$	969

Three months ended September 30, 2021 and September 30, 2020

General and administrative expense

For the three months ended September 30, 2021 and 2020 G&A expenses were $0.9 million and $1.2 million, respectively. The decrease is due to lower employee compensation expense which is the result of an accrual made in the third quarter of 2020 for nine months of incentive compensation expense compared to an accrual in the third quarter of 2021 for just one quarter of estimated expense.

Research and development expense

For the three months ended September 30, 2021 and 2020 R&D expenses were $1.3 million and $0.8 million, respectively. The increase was primarily due to higher spending on pre commercial manufacturing and preclinical research.

15

Other income (expense), net

Other expense, net, was $336,000 for the three months ended September 30, 2021 and is primarily the result of a foreign currency exchange loss. The net other income of approximately $236,000 in the three months ended September 30, 2020 is primarily a foreign exchange gain.

Income tax benefit

Income tax benefit increased to $404,000 for the three months ended September 30, 2021 up from $89,000 during the three months ended September 30, 2020. Our income tax benefit is derived primarily from refundable tax credits associated with our R&D activities conducted in Australia which were increased in the quarter.

Nine months ended September 30, 2021 and September 30, 2020

General and administrative expense

For the nine months ended September 30, 2021 and 2020 G&A expenses were $3.3 million and $2.3 million, respectively. The increase is due to higher employee compensation expense and incremental costs associated with our Nasdaq listing such as investor relations and insurance.

Research and development expense

For the nine months ended September 30, 2021 and 2020 R&D expenses were $3.4 million and $1.8 million, respectively. The increase was due primarily to increased spending on the pre commercial manufacturing.

Other income (expense), net

Other expense, net, was $0.6 million nine months ended September 30, 2021 and is primarily the result of a foreign currency exchange loss.

Income tax benefit

Income tax benefit increased to $722,000 for the nine months ended September 30, 2021 up from $222,000 during the nine months ended September 30, 2020. Our income tax benefit is derived primarily from refundable tax credits associated with our R&D activities conducted in Australia. A portion of this increase is related to a refund received in the nine months ended September 30, 2021 in excess of previously accrued refunds.

Liquidity and Capital Resources

The following table summarizes our liquidity and capital resources as of September 30, 2021 and December 31, 2020 and our cash flow data for the nine months ended September 30, 2021 and 2020. It is intended to supplement the more detailed discussion that follows (in thousands):

Liquidity and Capital Resources

Net change in cash and cash equivalents	$	5,050		$	8,421

Working Capital

Our total cash was $14.1 million and $9.0 million as of September 30, 2021 and December 31, 2020, respectively. We had $1.3 million in current liabilities and working capital of $13.4 million as of September 30, 2021, compared to $1.4 million in current liabilities and working capital of $8.4 million as of December 31, 2020.

Cash Flows

Net Cash Used in Operating Activities

Net cash used in operating activities was approximately $5.0 million in the nine months ended September 30, 2021 compared to $2.7 million in the nine months ended September 30, 2020. The net cash used in each of these periods primarily reflects the net loss for these periods and is partially offset by the effects of changes in operating assets and liabilities and non-cash stock compensation expense.

Net Cash Provided by Financing Activities

Net cash provided by financing activities was $10.1 million for the nine months ended September 30, 2021 and $11.2 million for the nine months ended September 30, 2020. The cash provided for the nine months ended September 30, 2021 represents the proceeds from the underwritten sale of common stock and the exercise of warrants during the first nine months of 2021. Cash provided for the nine months ended September 30, 2020 was the result of and underwritten sale of common stock and warrants and a private sale of common stock and warrants.

Capital Requirements

As we continue to pursue our operations and execute our business plan, including the wrapping up our current Phase 1 clinical trial and initiating a randomized trial for our initial product candidate, SBP-101, in pancreatic cancer, and pursuing regulatory approvals in the United States, the European Union and other international markets, we expect to continue to incur substantial and increasing losses, which will continue to generate negative net cash flows from operating activities.

Our future capital uses, and requirements depend on numerous current and future factors. These factors include, but are not limited to, the following:

● the progress of clinical trials required to support our applications for regulatory approvals, including wrapping up our Phase 1a /1b clinical trial, a human clinical trial in Australia and the United States and initiating a planned randomized trial to be started in by the end of 2021;

● the impact of the current COVID-19 pandemic on our ability to monitor our current clinical trial, initiate enrollment in a future clinical trial and procure the active ingredient;

● our ability to demonstrate the safety and effectiveness of our SBP-101 product candidate;

● our ability to obtain regulatory approval of our SBP-101 product candidate in the United States, the European Union or other international markets;

17

● the cost and delays in product development that may result from changes in regulatory oversight applicable to our SBP-101 product candidate;

● the market acceptance and level of future sales of our SBP-101 product candidate;

● the rate of progress in establishing reimbursement arrangements with third-party payors;

● the effect of competing technological and market developments; and

● the costs involved in filing and prosecuting patent applications and enforcing or defending patent claims.

To date, we have used primarily equity financings and convertible debt to fund our ongoing business operations and short-term liquidity needs, and we expect to continue this practice for the foreseeable future. As of September 30, 2021, we did not have any existing credit facilities under which we could borrow funds.

We expect that we will have increases in expenditures in order to continue our efforts to grow our business, complete our Phase 1 clinical trial and begin the next clinical trial for our SBP-101 product candidate. We also have begun to invest in additional R&D efforts on mechanism of action, biomarkers, additional indications in other cancer types and the possibility of SBP-101 to act as a sensitizing agent for certain immunotherapies. The exact amounts and timing of any expenditure may vary significantly from our current intentions. We will need to obtain additional funds to continue our operations and execute our business plans including completion of required future trials and pursuing regulatory approvals in the United States, the European Union and other international markets. While we have been successful in the past in obtaining the necessary capital to support our operations, and have similar future plans to obtain additional financing, there is no assurance that we will be able to obtain additional financing under commercially reasonable terms and conditions, or at all. This risk would increase if our clinical data were inconclusive or not positive or economic conditions worsened in the market as a whole or in the pharmaceutical or biotechnology markets individually.

If we are unable to obtain additional financing when needed, we will likely need to reduce our operations by taking actions which may include, among other things, reducing use of outside professional service providers, reducing staff size or reducing staff compensation, significantly modifying or delaying the development of our SBP-101 product candidate, licensing rights to third parties, including the right to commercialize our SBP-101 product candidate for patients with pancreatic cancer, or other applications that we would otherwise seek to pursue, or discontinuing operations entirely.

To the extent that we raise additional capital through the sale of equity or convertible debt securities, the interests of our current stockholders could be diluted, and the terms may include liquidation or other preferences that adversely affect the rights of our current stockholders. If we issue preferred stock, it could affect the rights of our stockholders or reduce the value of our common stock. Specific rights granted to future holders of preferred stock may include voting rights, preferences as to dividends and liquidation, conversion and redemption rights, sinking fund provisions, and restrictions on our ability to merge with or sell our assets to a third party. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. Any of these events could adversely affect our ability to achieve our regulatory approvals and commercialization goals and harm our business.

Our future success is dependent upon our ability to obtain additional financing, the success of our current Phase 1 clinical trial and required future trials, our ability to obtain marketing approval for our SBP-101 product candidate in the United States, the European Union and other international markets. If we are unable to obtain additional financing when needed, if our Phase 1 clinical trial is not successful, if we do not receive regulatory approval required for future trials or if once these studies are concluded, we do not receive marketing approval for our SBP-101 product candidate, we would not be able to continue as a going concern and would be forced to cease operations. The interim financial statements included in this report have been prepared assuming that we will continue as a going concern and do not include any adjustments relating to the recoverability or classification of assets or the amounts of liabilities that might result from the outcome of these uncertainties.

Indebtedness

As of September 30, 2021 and December 31, 2020 we had no debt obligations.

Critical Accounting Policies and Estimates

Our significant accounting policies are set forth in the notes accompanying the condensed consolidated financial statements included in this document. The accounting policies used in preparing our interim fiscal 2021 condensed consolidated financial statements are the same as those described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Item 3.       Quantitative and Qualitative Disclosure About Market Risk.

As a smaller reporting company, we are not required to provide disclosure pursuant to this item.

Item 4.       Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. As of the date of this filing, management has not identified any material weaknesses, but believes that it does have a significant deficiency in that it has insufficient personnel resources within the accounting function to fully segregate the duties over financial transaction processing and reporting. Management has mitigated this deficiency primarily through greater involvement in the review and monitoring of financial transaction processing and reporting by executive and senior management.

We believe that our internal control system provides reasonable assurance to our management and Board of Directors regarding the preparation and fair presentation of published financial statements. All internal controls over financial reporting, no matter how well designed, have inherent limitations, including the possibility of human error and the circumvention or overriding of controls. Therefore, even effective internal controls over financial reporting can provide only reasonable assurance with respect to financial statement preparation and presentation. Further, because of changes in conditions, the effectiveness of internal controls over financial reporting may vary over time.

As of the end of the period covered by this quarterly report, the Company’s management conducted an evaluation, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures, pursuant to Rules 13a-15 and 15d-15 of the Exchange Act. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of September 30, 2021, our disclosure controls and procedures were effective in ensuring that information relating to the Company required to be disclosed in the reports that we file or submit under the Securities Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, including ensuring that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes to Internal Control Over Financial Reporting

We have not identified any change in our internal control over financial reporting during our most recently completed fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1.       Legal Proceedings.

None.

Item 1A.     Risk Factors.

Other than as noted below, there have been no material changes to the risk factors included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

19

Our business is subject to risks arising from epidemic diseases, such as the 2020 outbreak of the COVID-19 illness.

The outbreak of COVID-19, which was declared in March 2020 by the World Health Organization to be a pandemic, has spread across the globe and is impacting worldwide economic activity. A pandemic, including COVID-19, or other public health epidemic poses the risk that we or our employees, contractors, suppliers, and other partners may be prevented from conducting business activities for an indefinite period of time, including due to the spread of the disease within these groups or due to shutdowns that may be requested or mandated by governmental authorities. During the second quarter of 2020 we paused enrollment in our clinical trial for 6 weeks to allow the health care systems involved in the trial time to focus resources on responding to the pandemic. We continued to treat patients previously enrolled. Once enrollment was restarted in May 2020, we experienced no further delays. This delay did not have a material effect on the completion of enrollment or costs of the clinical trial. During the course of the pandemic, health care facilities have limited our ability to conduct on site patient data monitoring for our clinical trial, these visits are now successfully conducted remotely as necessary. We also experienced a delay, approximately 30 to 60 days, early in the pandemic, in the manufacturing of our active ingredient. We believe our supply of drug is adequate and we do not expect this delay to disrupt the current trial or anticipated new trial to be initiated in 2021.

While we have not, to date experienced any significant disruptions as a result of the pandemic, we are unable to estimate the future impact that COVID-19 could have on our operations. The continued spread of COVID-19, limited availability of approved vaccines and measures taken by governmental authorities in light of the same may slow potential enrollment of clinical trials and reduce the number of eligible patients for our clinical trials. The pandemic could also disrupt the supply chain and the manufacture or shipment of both drug substance and finished drug product for our product candidates for preclinical testing and clinical trials and adversely impact our business, financial condition or results of operations. We often attend and present clinical updates at various medical and investor conferences throughout the year. The COVID-19 outbreak has caused, and is likely to continue to cause, cancellations or reduced attendance of these conferences and we may need to seek alternate methods to present clinical updates and to engage with the medical and investment communities. The COVID-19 outbreak and mitigation measures may also have an adverse impact on global economic conditions which could have an adverse effect on our business and financial condition and our potential to conduct financings on terms acceptable to us, if at all. The extent to which the COVID-19 outbreak impacts our results will depend on future developments that are highly uncertain and cannot be predicted, including new information that may emerge concerning the severity of the virus and the actions to contain its impact.

The Company did experience a modest delay in shipment of the active ingredient from India to the United States as a result of increased COVID-19 cases in India in the first half of 2021. The product was received early July 2021 for filling and labeling. Possible changes in the conduct of clinical trials has been considered in our planning assumptions as the Company plans for a new clinical trial to be initiated in many different locations, by the end of 2021. At this time no disruption to the initiation of the new trial is anticipated.
