Overview

We are a clinical-stage immunology company focused on developing drugs that may reprogram the patient’s innate immune system to treat disease. We believe this may be done by targeting cells of the innate immune system that cause acute and chronic inflammation and are involved in immune dysfunction associated with chronic diseases such as cancer and neurodegenerative diseases. The Company’s drugs are in clinical trials and have not been approved by a regulatory authority. The Company has two therapeutic platforms – a dominant-negative TNF platform (“DN-TNF”, “XPro™”, “XPro1595™” or “pegipanermin and pSar DN-TNF”) and a Natural Killer (“NK”, or “INKmune™”) platform. The DN-TNF platform neutralizes soluble TNF (“sTNF”) without affecting trans-membrane TNF (“tmTNF”) or TNF receptors -TNFR1 and TNFR2. This unique biologic mechanism differentiates the DN-TNF drugs from currently approved non-selective TNF inhibitors that inhibit both sTNF and tmTNF. Protecting the function of tmTNF and TNF receptors while neutralizing the function of sTNF is a potent anti-inflammatory strategy that does not cause immunosuppression or demyelination which occur in the currently approved non-selective TNF inhibitors. Currently approved non-selective TNF inhibitors treat autoimmune disease, but are contraindicated in patients with infection, cancer and neurologic diseases because they increase the risk of infection, cancer and demyelinating neurologic diseases, respectively; these safety problems are due to off-target effects on inhibiting tmTNF. The NK platform targets the dysfunctional natural killer cells in patients with cancer. NK cells are part of the normal immunologic response to cancer with important roles in immunosurveillance to prevent cancer and in preventing relapse by eliminating residual disease. Residual disease is the cancer left behind after therapy is finished. Residual disease can grow to cause relapse. The mechanism by which INKmune improves the ability of the patient’s NK cells to kill their cancer is complex. The NK cells of cancer patients lose the ability to bind and kill cancer cells. A measure of NK cell binding to cancer cells is avidity. The higher the avidity, the greater the bond between the NK cell to cancer cell and thus the greater NK killing of cancer cells. INKmune increases NK avidity and further improves mitochondrial function and upregulates nutrient receptors. These metabolic changes may help the INKmune primed NK cell to function in the hostile tumor microenvironment and persist much longer in the patient. These mechanisms improve the ability of INKmune primed NK cells to overcome the immune evasion of the patient’s cancer cells. We believe INKmune is best used to eliminate residual disease after the patient has completed other cancer therapies. Both the DN-TNF platform and the INKmune platform can be used to treat multiple diseases. The DN-TNF platform will be used as an immunotherapy for the treatment of cancer and neurodegenerative disease. INKmune is being developed to treat NK sensitive hematologic malignancies and solid tumors.

We believe our DN-TNF platform can be used as a cancer therapy to reduce resistance in immunotherapy and as a CNS (“central nervous system”) therapy to target glial activation to prevent progression of Alzheimer’s disease (“AD”), and to target neuroinflammation in treatment resistant depression (“TRD”) and as a drug to prevent muscle degeneration, prevent fibrosis and promote muscle regeneration in Duchene muscular dystrophy (“DMD”). The drug is named differently for the oncology and CNS indications; INB03™ or XPro™, respectively, but it is the same drug product. For DMD, the company is exploring pSar DN-TNF compounds optimized for the treatment of DMD. The pSar DN-TNF compound has the same mechanism of action, a different half-life extender and novel IP protection. In each case, we believe neutralizing sTNF is a cornerstone to the treatment of these diseases. As an immunotherapy for cancer, we are using INB03 to neutralize sTNF produced by HER2+ trastuzumab resistant breast cancers to reverse resistance to targeted therapy. sTNF produced by the tumor causes an up-regulation of MUC4 expression causing steric hindrance of trastuzumab binding to the HER receptor on HER2+ breast cancer cells. Without binding, trastuzumab based therapies are not effective. Neutralizing sTNF reverses MUC4 expression converting a trastuzumab resistant breast cancer cell into a trastuzumab sensitive breast cancer cell. In addition, INB03 changes the immunobiology of the tumor microenvironment by decreasing the number of immunosuppressive myeloid cells, both myeloid derived suppressor cells and tumor active macrophages, and increasing the number of cytotoxic lymphocytes and phagocytic macrophages in the TME. Recently, the Company has shown the combination for INB03 with trastuzumab-deruxtecan (Enhertu), decreases tumor growth in the multi-resistant JIMT-1 tumor model. The Company has completed an open label dose escalation trial in cancer patients with metastatic solid tumors that have failed multiple lines of therapy. The trial informs the design of the Phase II trial by demonstrating that INB03 was safe and well tolerated, defined the dose of INB03 to carry into Phase II trials, and demonstrated a pharmacodynamic endpoint – a decrease in inflammatory cytokines in the blood. A Phase II trial is planned in patients with advanced MUC4+ expressing cancer.

Likewise, we believe the DN-TNF platform can be used to treat selected neurodegenerative diseases by modifying the brain microenvironment (“BME”). The Company believes the core pathology of cognitive decline is a combination of neurodegeneration and synaptic dysfunction. Neurodegeneration is nerve cell death that may include demyelination. Synaptic dysfunction means the connections between nerve cells stop working efficiently and may decrease in number or become disconnected. The combination of neurodegeneration and synaptic dysfunction causes cognitive decline and behavioral changes associated with Alzheimer’s disease (“AD”). XPro completed a Phase I trial treating patients with Alzheimer’s disease that was partially funded by a Part-the-Clouds Award from the Alzheimer’s Association. We believe XPro targets activated microglia and astrocytes of the brain that produce sTNF that promotes nerve cell loss and synaptic dysfunction, key elements in the development of dementia. In animal models, elimination of sTNF prevents nerve cell dysfunction and reverses synaptic pruning. The Phase I trial in patients with biomarkers of inflammation with AD has been completed. The open label, dose escalation trial was designed to demonstrate that XPro can safely decrease neuroinflammation in patients with ADi. ADi is the term used to delineate patients with AD with biomarkers of inflammation. This appears to be more than 40% of patients with AD. The endpoints of the trial are measures of neuroinflammation and neurodegeneration in blood and cerebral spinal fluid by measuring changes in inflammatory cytokine levels in the CNS and using MRI-DTI to measure white matter free water. White matter free water is a validated measure of neuroinflammation in the brain. XPro, at the 1mg/kg/week dose decreased inflammatory cytokines in the CSF and decreased white matter free water in the brain demonstrating that XPro can decrease neuroinflammation in patients with ADi. We also studied downstream benefits of decreasing neuroinflammation by measuring changes in the CSF proteome and quantifying changes in novel white matter MRI biomarkers. XPro significantly decreases biomarkers of neurodegeneration as measured by changes in the CSF proteome including neurofilament light chain, phospho Tau 217 and VILIP-1; decreases of 84%, 46% and 91% respectively after 3 months of therapy. Three months of XPro therapy improved measures of synaptic function, as measured in the CSF proteome including a 222% increase in Contactin 2 and a 56% decrease neurogranin, changes that contribute to improved synaptic function.

The successful completion of the Phase I trial in AD has informed the design of a blinded randomized, placebo-controlled Phase II trials in patients with early ADi. Early ADi includes patients with AD and MCI who have at least one biomarker of inflammation (ADi and MCI² respectively). The early ADi trial is a blinded randomized trial to test if treatment of early AD patients with neuroinflammation with XPro will affect cognitive decline. The Phase II trial in early ADi has six important elements. Two hundred and ten patients are being enrolled in a 2:1 ratio (XPro vs placebo). The patients will receive 1mg/kg/week as a subcutaneous injection for six months. An enrichment strategy identical to the successful strategy used in the Phase I trial will be used to ensure patients have neuroinflammation. Patients will need to have one or more enrichment criteria: elevated blood level of at least one of C-reactive protein, hemoglobin A1c, erythrocyte sedimentation and/or at least one allele of ApoE4. The primary endpoint will be Early/ild Alzheimer’s Cognitive Composite (“EMACC”), a validated cognitive measure that is more sensitive than traditional end-points used in many studies of patients with early AD. The trial is open in Australia and Canada and will open in the US pending the lift of a clinical hold by the US FDA. All patients will be offered to stay on therapy for at least 12 months in an extension trial. Clinical and biomarker data will be collected during the extension trial.

Effective therapy for TRD is a large unmet need. Twenty percent of patients with a Major Depressive Disorder have TRD. Once third of TRD patients have peripheral biomarkers to inflammation (elevated CRP). This is a large patient population. The role of TNF and anti-TNF therapeutics was explored in a small open label clinical trial by Prof. Andrew Miller, MD of Emory University demonstrated the patients have elevated TNF levels and treatment with infliximab treated their depression (Miller, 2011). The Company received a $2.9M USD award from the National Institute of Mental Health (“NIMH”) to treat TRD with XPro. The blinded, randomized Phase II trial will use biomarkers of peripheral inflammation to select patients with TRD for enrollment. Patients will be treated for 6 weeks. Primary endpoints include both clinical and neuroimaging measures. The final trial design is ongoing and discussions with the FDA are not complete. The Company anticipates receiving authorization to initiate the clinical trial once the pending clinical hold is lifted.

The Company completed an extensive series of studies in murine models of DMD. The data shows DN-TNF decreases muscle fiber inflammation and degeneration, increases muscle fiber regeneration in an acute model of DMD. Cardiac function was studied using echocardiography after 30 weeks of treatment. Cardiac function did not change compared to placebo treated or prednisone treated animals. These data strongly suggest DN-TNF may be a therapy for treatment of patients with DMD that may have unique biologic attributes, muscle fiber regeneration, without corticosteroid associated metabolic toxicity – insulin resistance, diabetes, obesity, hirsutism, short stature and muscle weakness.

We believe that INKmune improves the ability of the patient’s own NK cells to attack their tumor. INKmune interacts with the patient’s NK cells to convert them from inert resting NK cells into memory-like NK cells that kill the patient’s cancer cells. INKmune is a replication incompetent proprietary cell line that is given to the patient after determining that i) the patient has adequate NK cells in their circulation and ii) those NK cells are functional when exposed to INKmune in vitro. INKmune is designed to be given to patients after their immune system has recovered after cytotoxic chemotherapy to target the residual disease the remains after treatment with cytotoxic therapy. We believe INKmune can be used to treat numerous hematologic malignancies and solid tumors including leukemia, multiple myeloma, lymphoma, lung, ovary, breast, renal, nasopharyngeal and prostate cancer. The Company has initiated a Phase I trial using INKmune to treat patients with high risk MDS/AML, a form of leukemia. Two patients have been treated in the Phase I trial for MDS and three patients have been treated compassionately in AML. In the five patients, INKmune therapy is safe, produces memory-like NK cells that kill cancer in vitro, promotes development of cancer killing memory-like NK cells that can be found in the patient’s circulation of 4 months. The Company will continue to enroll patients in the Phase I trial. The Company intends to initiate a separate Phase I/II trial of INKmune in a metastatic castration resistant prostate cancer (“mCRPC”) tumor during 2024. An IND for a Phase I/II trial in men with mCRPC was opened in May 2023. The trial will treat up to 30 patients with mCRPC in a open label trial. The trial has four goals: i) demonstrate safety of INKmune in men with mCRPC; ii) determine what dose of INKmune should be used in a blinded randomized Phase II trial on men with mCRPC; iii) determine tumor response using traditional biomarkers of mCRPC including blood PSA level and iv) use exploratory biomarkers of tumor response including circulating tumor DNA and PET PMSA imaging studies. The first patients should be treated 9 months after the IND is open.

You may experience immediate and substantial dilution in the net tangible book value per share of the common stock you purchase in the offering. In addition, we may issue additional equity or convertible debt securities in the future, which may result in additional dilution to you.

The offering price per share in this offering may exceed the pro forma net tangible book value per share of our common stock outstanding as of June 30, 2023. Assuming that we sell an aggregate of 3,495,878 shares of our common stock at a price of $8.21 per share, the last reported sale price of our common stock on Nasdaq on August 14, 2023, for aggregate gross proceeds of approximately $28,701,161, and after deducting commissions and estimated aggregate offering expenses payable by us, you will experience immediate dilution of $5.32 per share, representing the difference between our pro forma as adjusted net tangible book value per share as of June 30, 2023, after giving effect to this offering and the assumed offering price. See the section titled “Dilution” below for a more detailed illustration of the dilution you would incur if you participate in this offering. In addition, to the extent we need to raise additional capital in the future and we issue additional shares of common stock or securities convertible or exchangeable for our common stock, our then existing stockholders may experience dilution and the new securities may have rights senior to those of our common stock offered in this offering.

We may issue and sell shares of our common stock having aggregate gross sales proceeds of up to $28,701,161.61 from time to time. Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time.

We will retain broad discretion over the use of the net proceeds from the sale of the securities offered hereby. We currently intend to use the net proceeds from this offering for general corporate purposes, including to support research and development, including clinical trials. The precise amount and timing of the application of such proceeds will depend upon our funding requirements and the availability and cost of other capital. As of the date of this prospectus supplement, we cannot specify with certainty all of the particular uses for the net proceeds that we will have from the sale of the shares of our common stock. Pending the use of the net proceeds from this offering, if any, we may invest the net proceeds in investment grade, short-term interest-bearing obligations, such as money-market funds, certificates of deposit, or direct or guaranteed obligations of the United States government, or hold the net proceeds as cash.

If you purchase shares of our common stock in this offering, your interest will be diluted to the extent of the difference between the public offering price per share and the net tangible book value per share of our common stock after this offering. We calculate net tangible book value per share by dividing our net tangible assets (tangible assets less total liabilities) by the number of shares of our common stock issued and outstanding as of June 30, 2023.

Our historical net tangible book value at June 30, 2023 was $34,140,000 or approximately $1.90 per share of our common stock. After giving effect to the sale of our common stock in the aggregate amount of approximately $28,701,161 in this offering, at an assumed offering price of $8.21 per share, the last reported sale price of our common stock on Nasdaq on August 14, 2023, and after deducting estimated offering expenses and commissions payable by us, our adjusted net tangible book value as of June 30, 2023 would have been approximately $61,890,000 or approximately $2.89 per share of our common stock. This represents an immediate increase in the net tangible book value of $0.99 per share of our common stock to our existing stockholders and an immediate dilution in net tangible book value of approximately $5.32 per share of our common stock to new investors. The following table illustrates per share dilution:

The table above assumes for illustrative purposes that an aggregate of 3,495,878 shares of our common stock are sold at a price of $8.21 per share, the last reported sale price of our common stock on Nasdaq on August 14, 2023, for aggregate gross proceeds of approximately $28,701,161. The shares sold in this offering, if any, will be sold from time to time at various prices. An increase of $2.00 per share in the price at which the shares are sold from the assumed offering price of $8.21 per share shown in the table above, assuming all of our common stock in the aggregate amount of $28,701,161 is sold at that price, would increase our adjusted net tangible book value per share after the offering to $2.98 per share and would increase the dilution in net tangible book value per share to new investors in this offering to $7.23 per share, after deducting estimated offering expenses and commissions payable by us. A decrease of $2.00 per share in the price at which the shares are sold from the assumed offering price of $8.21 per share shown in the table above, assuming all of our common stock in the aggregate amount of $28,701,161 is sold at that price, would decrease our adjusted net tangible book value per share after the offering to $2.74 per share and would decrease the dilution in net tangible book value per share to new investors in this offering to $3.47 per share, after deducting estimated offering expenses and commissions payable by us. This information is supplied for illustrative purposes only.

The information above is based on 17,945,995 shares of our common stock outstanding as of June 30, 2023, and excludes:

In addition, the above discussion and table do not include 75,697 shares of the Company’s common stock sold during July 2023 pursuant to the Sales Agreement.

To the extent that outstanding options or warrants are exercised, or we issue other shares, investors purchasing shares in this offering could experience further dilution. In addition, to the extent that we raise additional capital through the sale of equity or convertible debt securities, the issuance of those securities could result in further dilution to our stockholders.

We have entered into the sales agreement with BTIG under which we may issue and sell shares of our common stock having an aggregate offering price of up to $45,000,000 from time to time through BTIG, acting as our sales agent. On August 16, 2023, we entered into an amendment to the sales agreement in order to update the registration statement that this prospectus forms a part of. As the date of this prospectus we have sold $16,298,838.39 of shares of our common stock pursuant to the sales agreement and issued 788,889 shares of our common stock and may sell up to an additional $28,701,161.61 of shares of our common stock. The sales of our common stock, if any, under this prospectus supplement will be made at market prices by any method deemed to be an “at the market offering” as defined in Rule 415(a)(4) under the Securities Act, including sales made directly on The Nasdaq Capital Market, on any other existing trading market for our common stock, or to or through a market maker.

Each time that we wish to issue and sell shares of our common stock under the sales agreement, we will provide BTIG with a placement notice describing the amount of shares to be sold, the time period during which sales are requested to be made, any limitation on the amount of shares of common stock that may be sold in any single day, any minimum price below which sales may not be made or any minimum price requested for sales in a given time period and any other instructions relevant to such requested sales. Upon receipt of a placement notice, BTIG, acting as our sales agent, will use commercially reasonable efforts, consistent with its normal trading and sales practices and applicable state and federal laws, rules and regulations and the rules of the Nasdaq Capital Market, to sell shares of our common stock under the terms and subject to the conditions of the placement notice and the sales agreement. We or BTIG may suspend the offering of common stock pursuant to a placement notice upon notice and subject to other conditions. BTIG, in its sole discretion, may decline to accept any placement notice.

BTIG will provide written confirmation to us no later than the opening of the trading day on the Nasdaq Capital Market following the trading day on which shares of our common stock are sold through BTIG as sales agent under the sales agreement. Each confirmation will include the number of shares sold on the preceding day, the net proceeds to us and the commissions payable by us to BTIG in connection with the sales.

Settlement for sales of common stock under the sales agreement will occur on the second trading day following the date on which such sales are made (or on such other date as is industry practice for regular-way trading), unless otherwise specified in the applicable placement notice, in return for payment of the net proceeds to us. There are no arrangements to place any of the proceeds of this offering in an escrow, trust or similar account. Sales of our common stock as contemplated in this prospectus supplement will be settled through the facilities of The Depository Trust Company or by such other means as we and BTIG may agree upon.

We will pay BTIG commissions for its services in acting as our sales agent in the sale of our common stock pursuant to the sales agreement. BTIG will be entitled to compensation at a fixed commission rate of 3.0% of the gross proceeds from the sale of our common stock on our behalf pursuant to the sales agreement. We also have agreed to reimburse BTIG for its reasonable out-of-pocket expenses, including the fees and disbursements of BTIG’s counsel, incurred in connection with entering into the sales agreement, in an amount not to exceed $50,000, plus additional amounts, not to exceed $7,500 per calendar quarter during which shares of our common stock have been sold under the sales agreement, to reimburse BTIG for additional out-of-pocket expenses it may incur after the date of this prospectus supplement in connection with this offering.

We estimate that the total expenses for this offering, excluding compensation payable to BTIG and certain expenses reimbursable to BTIG under the terms of the sales agreement, will be approximately $90,000. The remaining sales proceeds, after deducting any expenses payable by us and any transaction fees imposed by any governmental, regulatory, or self-regulatory organization in connection with the sales, will equal our net proceeds for the sale of such common stock.

Because there are no minimum sale requirements as a condition to this offering, the actual total public offering price, commissions and net proceeds to us, if any, are not determinable at this time. The actual dollar amount and number of shares of common stock we sell through this prospectus supplement will be dependent, among other things, on market conditions and our capital raising requirements.

We will report at least quarterly the number of shares of common stock sold through BTIG under the sales agreement, the net proceeds to us and the compensation paid by us to BTIG in connection with the sales of common stock.

In connection with the sale of the common stock on our behalf, BTIG will be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation of BTIG will be deemed to be underwriting commissions or discounts. We have agreed to provide indemnification and contribution to BTIG against certain civil liabilities, including liabilities under the Securities Act or the Exchange Act.

BTIG will not engage in any market making activities involving our common stock while the offering is ongoing under this prospectus supplement if such activity would be prohibited under Regulation M or other anti-manipulation rules under the Securities Act. As our sales agent, BTIG will not engage in any transactions that stabilizes our common stock.

The offering pursuant to the sales agreement will terminate upon the earlier of (i) the sale of all shares of common stock subject to the sales agreement and (ii) termination of the sales agreement as permitted therein. We may terminate the sales agreement in our sole discretion at any time by giving 10 days’ prior notice to BTIG. BTIG may terminate the sales agreement under the circumstances specified in the sales agreement and in its sole discretion at any time by giving 10 days’ prior notice to us.

The sales agreement has been filed as an exhibit to a current report on Form 8-K that we filed with the SEC in connection with this offering and is incorporated into this prospectus supplement by reference.

BTIG has provided, and BTIG and/or its affiliates may in the future provide, various investment banking and other financial services for us, for which BTIG has received, and BTIG and/or its affiliates may in the future receive, customary fees and commissions.

The validity of the securities offered by this prospectus will be passed upon by Sichenzia Ross Ference LLP, New York, New York. Certain matters will be passed upon for BTIG by Lowenstein Sandler LLP, New York, New York.

We are an “emerging growth company” under applicable Securities and Exchange Commission, or the SEC, rules and, as such, have elected to comply with certain reduced public company reporting requirements for this prospectus and future filings.

This prospectus may not be used to offer and sell securities unless accompanied by a prospectus supplement.

Our common stock is currently traded on the NASDAQ Capital Market under the symbol “INMB.” On March 9, 2021, the last reported sales price for our common stock was $13.73 per share.

This prospectus is part of a registration statement that we filed with the Securities and Exchange Commission, or SEC, using a “shelf” registration process. Under this shelf registration process, we may sell any combination of the securities described in this prospectus in one of more offerings up to a total dollar amount of proceeds of $250,000,000. This prospectus describes the general manner in which our securities may be offered by this prospectus. Each time we sell securities, we will provide a prospectus supplement that will contain specific information about the terms of that offering. The prospectus supplement may also add, update or change information contained in this prospectus or in documents incorporated by reference in this prospectus. The prospectus supplement that contains specific information about the terms of the securities being offered may also include a discussion of certain U.S. Federal income tax consequences and any risk factors or other special considerations applicable to those securities.

The terms “INmune Bio,” the “Company,” “we,” “our,” or “us,” in this prospectus refer to INmune Bio Inc. and its wholly-owned subsidiaries, unless the context suggests otherwise.

This prospectus and the documents and information incorporated by reference in this prospectus include forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. These statements are based on our management’s beliefs and assumptions and on information currently available to our management. All statements, other than statements of historical fact, included regarding our strategy, future operations, financial position, future revenues, projected costs, plans, prospects and objectives are forward-looking statements. Words such as “expect,” “anticipate,” “intend,” “plan,” “believe,” “seek,” “estimate,” “think,” “may,” “could,” “will,” “would,” “should,” “continue,” “potential,” “likely,” “opportunity” and similar expressions or variations of such words are intended to identify forward-looking statements but are not the exclusive means of identifying forward-looking statements. Examples of our forward-looking statements include:

Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified and some of which are beyond our control, you should not rely on these forward-looking statements as predictions of future events. The events and circumstances reflected in our forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements. Moreover, we operate in an evolving environment. New risk factors and uncertainties may emerge from time to time, and it is not possible for management to predict all risk factors and uncertainties. Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements contained herein, whether as a result of any new information, future events, changed circumstances or otherwise.

This prospectus and the documents incorporated herein by reference also refer to estimates and other statistical data made by independent parties and by us relating to market size and growth and other data about our industry. This data involves a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. In addition, projections, assumptions and estimates of our future performance and the future performance of the markets in which we operate are necessarily subject to a high degree of uncertainty and risk.

We are a clinical-stage immunotherapy company focused on reprogramming the patient’s innate immune system to treat disease. We do this by targeting four key cells of the innate immune system, natural killer, or NK cells, and myeloid derived suppressor cells, or MDSC, hepatic stellate cells of the liver, or HSC, and microglial cells of the central nervous system. NK cells are the body’s first line of defense due to their innate ability to rapidly seek and destroy abnormal cells, such as cancer or virally-infected cells, without prior exposure or activation by other support molecules required to activate adaptive immune cells such as T-cells. NK cells play a key role in the immune-surveillance that prevents people from getting cancer and in eliminating residual disease which may cause people to relapse after cytotoxic therapy. MDSC are myeloid cells produced in the bone marrow, take up residence in the tumor microenvironment, the tissue associated with the cancerous cells, to protect the tumor from immunological attack by the patient’s immune system. MDSC play a critical role in making the cancer resistant to immunotherapy such as currently approved checkpoint inhibitors. Microglial cells are the primary immune cells of the central nervous system responsible for protecting the neural unit of microglia, astrocytes, oligodendrocytes and neurons from infection. In the setting of chronic inflammation, microglial cells become activated and cause dysfunction of the other three cells types in the neural unit resulting in neurodegenerative and neuropsychiatric diseases. Hepatic stellate cells are immunologically active cells that are part of the liver architecture that support hepatocyte function in health and disease. INB03, LivNate and XPro1595 are the identical drug used in different therapeutic arenas. INB03 is the name of the drug for cancer targeted applications. XPro1595 in the name of the drug for neurology and psychiatric indications. LivNate is the name of the drug for treatment of liver diseases.

We believe INKmune, our NK cell directed therapy, and INB03, our MDSC directed therapy, and XPro1595, our microglial directed therapy and LivNate, our HSC directed therapy offer unique strategies to improve the response of patients’ innate immune system to their cancer, neurologic and liver disease respectively. These therapies will use a precision medicine approach to select patients who will benefit from the therapy and monitor the response to the therapy. For oncology, neither INB03 nor INKmune therapy is cancer specific. The decision to use either INKmune or INB03 as part of cancer therapies, or with each other, depends on immunologic parameters that can be tested in patients before treatment. The type of cancer is not important. This means that both therapies can be used to treat patients with a variety of hematologic malignancies and solid tumors that have the immunologic profile needed to respond. Put simply, we are treating the immune system to attack the patients’ cancer, not targeting the patient’s cancer directly.

We believe that INKmune improves the ability of the patient’s own NK cells to attack their tumor. INKmune itself will not kill cancer cells. INKmune interacts with the patient’s NK cells to convert them from inert resting NK cells that ignores the cancer into primed NK cells that kill the cancer cell. INKmune is a replication incompetent proprietary cell line we have named INB16 that is given to the patient after determining that i) the patient has adequate NK cells in their circulation and ii) those NK cells are functional when exposed to INKmune in vitro. INKmune is designed to be given to patients after their immune system has recovered after cytotoxic chemotherapy to target the residual disease the remains after treatment with cytotoxic therapy.

Likewise, we believe XPro1595, our microglial directed therapy, offers a unique strategy to decrease neuroinflammation, a key pathophysiology in neurodegenerative and neuropsychiatric diseases. XPro1595 will use a precision medicine approach to select patients who will benefit from the therapy and monitor the response to the therapy. The therapy is not diagnosis specific but will be used in patients who have biomarkers of neuroinflammation. Our initial program with XPro1595 will be treating patients with Alzheimer’s disease with biomarkers inflammation.

Likewise, we believe LivNate, our HSC directed therapy, offers a unique strategy to treat NASH by decreasing peripheral , regional and local inflammatory cycles that results in hepatocyte ballooning and death, hepatitis and fibrosis, the core pathophysiology of many inflammatory liver diseases. Our initial program with LivNate will be treating patients with NASH.

We reported a net loss of $12,099,159 and $7,678,313 for the years ended December 31, 2020 and 2019, respectively. We have an accumulated deficit of $33,375,340 as of December 31, 2020.

Implications of Being an Emerging Growth Company and a Smaller Reporting Company

As a company with less than $1.07 billion in revenue during our last fiscal year, we qualify as an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. An emerging growth company may take advantage of reduced reporting requirements that are otherwise applicable to public companies. These provisions include, but are not limited to:

We may take advantage of these provisions until the last day of our fiscal year following the fifth anniversary of our initial public offering. 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 $1.07 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 prospectus and may elect to take advantage of other reduced reporting requirements in future filings. As a result, the information that we provide to our stockholders may be different from what you might receive from other public reporting companies in which you hold equity interests.

In addition, under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards until such time as those standards apply to private companies.

We are also a “smaller reporting company,” as that term is defined in Rule 12b-2 under the Exchange Act. As a result, many of the same exemptions from reporting requirements available to us as an emerging growth company are also available to us as a smaller reporting company, including not being required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act and reduced disclosure obligations regarding executive compensation. To the extent that we continue to qualify as a smaller reporting company, after we cease to qualify as an emerging growth company, those exemptions may continue to be available to us.

Our principal executive offices are located at 1200 Prospect Street, Suite 525, La Jolla, California 92037. Our telephone number is (858) 964-3720. We maintain an Internet website at www.inmunebio.com. The information contained on, connected to or that can be accessed via our website is not part of this prospectus.

Investing in our securities involves a high degree of risk. Before making an investment decision, you should consider carefully the risks, uncertainties and other factors described in our most recent Annual Report on Form 10-K, as supplemented and updated by subsequent quarterly reports on Form 10-Q and current reports on Form 8-K that we have filed or will file with the SEC, which are incorporated by reference into this prospectus.

Our business, affairs, prospects, assets, financial condition, results of operations and cash flows could be materially and adversely affected by these risks. For more information about our SEC filings, please see “Where You Can Find More Information”.

Unless otherwise indicated in a prospectus supplement, we intend to use the net proceeds from the sale of the securities under this prospectus for general corporate purposes, including to support research and development, including clinical trials, and general corporate purposes.

The following description of our capital stock, together with any additional information we include in any applicable prospectus supplement or any related free writing prospectus, summarizes the material terms and provisions of our common stock and the preferred stock that we may offer under this prospectus. While the terms we have summarized below will apply generally to any future common stock or preferred stock that we may offer, we will describe the particular terms of any class or series of these securities in more detail in the applicable prospectus supplement. For the complete terms of our common stock and preferred stock, please refer to our articles of incorporation and our bylaws that are incorporated by reference into the registration statement of which this prospectus is a part. The summary below and that contained in any applicable prospectus supplement or any related free writing prospectus are qualified in their entirety by reference to our articles of incorporation and our bylaws.

We are authorized to issue 200,000,000 shares of common stock, $0.001 par value per share. As of the date of this prospectus, there are 14,932,638 shares of common stock issued and outstanding. The outstanding shares of common stock are validly issued, fully paid and nonassessable.

Holders of common stock are entitled to one vote for each share on all matters submitted to a stockholder vote. Holders of common stock do not have cumulative voting rights. Therefore, holders of a majority of the shares of common stock voting for the election of directors can elect all of the directors. Holders of common stock representing a majority of the voting power of our capital stock issued, outstanding and entitled to vote, represented in person or by proxy, are necessary to constitute a quorum at any meeting of stockholders. A vote by the holders of a majority of the Company’s outstanding shares is required to effectuate certain fundamental corporate changes such as liquidation, merger or an amendment to the Company’s certificate of incorporation.

Holders of common stock are entitled to share in all dividends that our Board of Directors, in its discretion, declares from legally available funds. In the event of a liquidation, dissolution or winding up, each outstanding share entitles its holder to participate pro rata in all assets that remain after payment of liabilities and after providing for each class of stock, if any, having preference over the common stock. The common stock has no pre-emptive, subscription or conversion rights and there are no redemption provisions applicable to the common stock.

We are authorized to issue up to 10,000,000 shares of preferred stock, par value $0.001 per share, from time to time in one or more series. On December 30, 2020, we filed a Certificate of Designation of Series A Junior Preferred Stock with the Secretary of State of the State of Delaware to designate 45,000 shares as Series A Preferred Junior Participating Preferred Stock. As of the date of this prospectus, there were no shares of our preferred stock outstanding.

Our articles of incorporation authorizes our Board of Directors to issue preferred stock from time to time with such designations, preferences, conversion or other rights, voting powers, restrictions, dividends or limitations as to dividends or other distributions, qualifications or terms or conditions of redemption as shall be determined by the Board of Directors for each class or series of stock. Preferred stock is available for possible future financings or acquisitions and for general corporate purposes without further authorization of stockholders unless such authorization is required by applicable law, the rules of the NASDAQ Capital Market or other securities exchange or market on which our stock is then listed or admitted to trading.

Our Board of Directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of common stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes could, under some circumstances, have the effect of delaying, deferring or preventing a change-in-control of the Company.

A prospectus supplement relating to any series of preferred stock being offered will include specific terms relating to the offering. Such prospectus supplement will include:

The terms, if any, on which the preferred stock may be convertible into or exchangeable for our common stock will also be stated in the preferred stock prospectus supplement. The terms will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at our option, and may include provisions pursuant to which the number of shares of our common stock to be received by the holders of preferred stock would be subject to adjustment.

The transfer agent for our common stock is VStock Transfer, LLC. The transfer agent’s address is 18 Lafayette Place, Woodmere, New York 11598.

Our common stock is currently traded on the NASDAQ Capital Market under the symbol “INMB”.

We may issue warrants for the purchase of preferred stock or common stock. Warrants may be issued independently or together with any preferred stock or common stock, and may be attached to or separate from any offered securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between a warrant agent specified in the agreement and us. The warrant agent will act solely as our agent in connection with the warrants of that series and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants. This summary of some provisions of the securities warrants is not complete. You should refer to the securities warrant agreement, including the forms of securities warrant certificate representing the securities warrants, relating to the specific securities warrants being offered for the complete terms of the securities warrant agreement and the securities warrants. The securities warrant agreement, together with the terms of the securities warrant certificate and securities warrants, will be filed with the SEC in connection with the offering of the specific warrants.

The applicable prospectus supplement will describe the following terms, where applicable, of the warrants in respect of which this prospectus is being delivered:

Warrants for the purchase of common stock or preferred stock will be offered and exercisable for U.S. dollars only. Warrants will be issued in registered form only.

Upon receipt of payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement, we will, as soon as practicable, forward the purchased securities. If less than all of the warrants represented by the warrant certificate are exercised, a new warrant certificate will be issued for the remaining warrants.

Prior to the exercise of any securities warrants to purchase preferred stock or common stock, holders of the warrants will not have any of the rights of holders of the common stock or preferred stock purchasable upon exercise, including in the case of securities warrants for the purchase of common stock or preferred stock, the right to vote or to receive any payments of dividends on the preferred stock or common stock purchasable upon exercise.

As specified in the applicable prospectus supplement, we may issue units consisting of shares of common stock, shares of preferred stock or warrants or any combination of such securities.

The applicable prospectus supplement will specify the following terms of any units in respect of which this prospectus is being delivered:

We may sell the securities offered through this prospectus (i) to or through underwriters or dealers, (ii) directly to purchasers, including our affiliates, (iii) through agents, or (iv) through a combination of any these methods. The securities may be distributed at a fixed price or prices, which may be changed, market prices prevailing at the time of sale, prices related to the prevailing market prices, or negotiated prices. The prospectus supplement will include the following information:

Only underwriters named in the prospectus supplement are underwriters of the securities offered by the prospectus supplement.

If underwriters are used in the sale, the underwriters will acquire the securities for their own account, including through underwriting, purchase, security lending or repurchase agreements with us. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions. Underwriters may sell the securities in order to facilitate transactions in any of our other securities (described in this prospectus or otherwise), including other public or private transactions and short sales. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless otherwise indicated in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions, and the underwriters will be obligated to purchase all the offered securities if they purchase any of them. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers.

If dealers are used in the sale of securities offered through this prospectus, we will sell the securities to them as principals. They may then resell those securities to the public at varying prices determined by the dealers at the time of resale. The prospectus supplement will include the names of the dealers and the terms of the transaction.

We may sell the securities offered through this prospectus directly. In this case, no underwriters or agents would be involved. Such securities may also be sold through agents designated from time to time. The prospectus supplement will name any agent involved in the offer or sale of the offered securities and will describe any commissions payable to the agent. Unless otherwise indicated in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. The terms of any such sales will be described in the prospectus supplement.

If the prospectus supplement indicates, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The applicable prospectus supplement will describe the commission payable for solicitation of those contracts.

Without limiting the generality of the foregoing, we may enter into a continuous offering program equity distribution agreement with a broker-dealer, under which we may offer and sell shares of our common stock from time to time through a broker-dealer as our sales agent. If we enter into such a program, sales of the shares of common stock, if any, will be made by means of ordinary brokers’ transactions on the NASDAQ Capital Market at market prices, block transactions and such other transactions as agreed upon by us and the broker-dealer. Under the terms of such a program, we also may sell shares of common stock to the broker-dealer, as principal for its own account at a price agreed upon at the time of sale. If we sell shares of common stock to such broker-dealer as principal, we will enter into a separate terms agreement with such broker-dealer, and we will describe this agreement in a separate prospectus supplement or pricing supplement.

Unless the applicable prospectus supplement states otherwise, other than our common stock all securities we offer under this prospectus will be a new issue and will have no established trading market. We may elect to list offered securities on an exchange or in the over-the-counter market. Any underwriters that we use in the sale of offered securities may make a market in such securities, but may discontinue such market making at any time without notice. Therefore, we cannot assure you that the securities will have a liquid trading market.

Any underwriter may also engage in stabilizing transactions, syndicate covering transactions and penalty bids in accordance with Rule 104 under the Securities Exchange Act. Stabilizing transactions involve bids to purchase the underlying security in the open market for the purpose of pegging, fixing or maintaining the price of the securities. Syndicate covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover syndicate short positions.

Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time.

Agents, underwriters, and dealers may be entitled, under agreements entered into with us, to indemnification by us against certain liabilities, including liabilities under the Securities Act. Our agents, underwriters, and dealers, or their affiliates, may be customers of, engage in transactions with or perform services for us, in the ordinary course of business.

The validity of the issuance of the securities offered by this prospectus will be passed upon for us by Sichenzia Ross Ference LLP, New York, New York.

The following documents are incorporated by reference and made a part of this prospectus:

We also incorporate by reference any future filings (other than information furnished under Item 2.02 or Item 7.01 of Form 8-K and exhibits furnished on such form that are related to such items unless such Form 8-K expressly provides to the contrary) made with the SEC pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act, including those made after the date of the initial filing of the registration statement of which this prospectus is a part and prior to effectiveness of such registration statement, until we file a post-effective amendment that indicates the termination of the offering of the common stock made by this prospectus and will become a part of this prospectus from the date that such documents are filed with the SEC. Information in such future filings updates and supplements the information provided in this prospectus. Any statements in any such future filings will automatically be deemed to modify and supersede any information in any document we previously filed with the SEC that is incorporated or deemed to be incorporated herein by reference to the extent that statements in the later filed document modify or replace such earlier statements.

Notwithstanding the foregoing, information furnished under Items 2.02 and 7.01 of any Current Report on Form 8-K, including the related exhibits, is not incorporated by reference in this prospectus.
