Description of Business

Overview

Description of Business

Overview

We are a clinical-stage inflammation and immunology company focused on developing drugs that modify the patient’s innate immune system to treat disease. We believe targeting cells of the innate immune system that cause chronic inflammation and are involved in immune dysfunction such as cancer and neurodegenerative diseases may make a therapeutic impact on many 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™”, “INB03”, or “pegipanermin”) 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. 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 can occur with currently approved non-selective TNF inhibitors and may occur with many other potent anti-inflammatory drugs. 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; 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 immune 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 NK cells of cancer patients lose the ability to bind and kill cancer cells. INKmune converts the patient’s resting NK cells into cancer killing memory like NK cells (mlNK). INKmune improves mlNK killing in the hostile tumor microenvironment in at least three ways: increasing avidity, improving mitochondrial and cellular respiration and allowing the cells to function in the immunosuppressive and hypoxic TME. Avidity is a measure of NK cell binding to cancer cells. 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. These mechanisms improve the ability of INKmune™ primed NK cells to overcome the immune evasion of the patient’s cancer cells. We believe INKmune™ may be 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 (INB03) and neurodegenerative disease. INKmune™ is being developed to treat NK-resistant hematologic malignancies and solid tumors.   

We believe our DN-TNF platform can be used as a CNS (“central nervous system”) therapy to target glial activation to prevent progression of Alzheimer’s disease (“AD”); to target neuroinflammation in treatment resistant depression (“TRD”); as a drug to treat many chronic inflammatory diseases; and as a cancer therapy to reduce resistance in immunotherapy. The primary focus of the company’s development efforts for XPro™ is AD which is currently in a Phase 2 trial to determine if reduction of chronic inflammation without immunosuppression makes a difference in cognition. The next indication to be developed with XPro™ will be TRD. There is a significant pre-clinical program on the use on DN-TNF in cancer. The drug is named differently for the oncology and CNS indications; INB03™ or XPro, respectively, but it is the same drug product. This novel compound has the same mechanism of action but has novel IP protection. In each case, we believe neutralizing sTNF without blocking tmTNF or TNF receptors 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 express 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 mouse models, INB03 changes the immunobiology of the tumor microenvironment (“TME”) by decreasing the number of immunosuppressive myeloid cells, both myeloid derived suppressor cells and tumor active macrophages (TAM; phagocytic macrophages) in the TME. In the TME of immunocompetent mice, INB03 increases the number of cytotoxic lymphocytes modifies and the TME by downregulating immune exhaustion markers – PDL-1, TIGIT, LAG3, CTLA4, CD47 and SIRPꭤ. 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 pre-clinical data in MUC4+ expressing tumors and the clinical trial informs the design of a future 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. The company does not plan to commence a Phase II trial in patients with advanced MUC4+ expressing cancer until a partner can be found or extra-mural funding is secured.

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. 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 causing nerve cell loss, synaptic dysfunction and prevents myelin repair - key elements in the development of dementia. In animal models, elimination of sTNF prevents nerve cell dysfunction, reverses synaptic pruning and promotes myelin repair. 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. The endpoints of the trial were measures of neuroinflammation and neurodegeneration in blood and cerebral spinal fluid by measuring changes in inflammatory cytokine levels in the CNS. XPro, at the 1mg/kg/week dose, decreased inflammatory cytokines in the CSF in the brain demonstrating that XPro can decrease neuroinflammation in patients with AD. We also studied downstream benefits of decreasing neuroinflammation by measuring changes in the CSF proteome and using EEG as a functional measure of brain function. 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. After 4 weeks of XPro therapy, EEG Alpha power improved in patients with AD suggesting improved brain activity.

The successful completion of the Phase I trial in AD informed the design of the ongoing blinded randomized, placebo-controlled Phase II trial in patients with early AD with biomarkers of inflammation. Early ADi. Early ADi includes patients have mild AD or MCI with at least one biomarker of inflammation. 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 one 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 or at least one allele of ApoE4. The primary endpoint will be Early/mild Alzheimer’s Cognitive Composite (“EMACC”), a validated cognitive measure that is more sensitive than traditional endpoints used in many studies of patient with early AD. Although EMACC is a primary endpoint, CDR-SB, a well recognized cognitive test is being used as a secondary endpoint as well. The AD program is enrolling patients in Australia, Canada, the United Kingdom, France, Germany, Spain, Poland, Czech Republic and Slovakia. Because of resource constraints, a planned open-label extension has been stopped. 

There are at least 4 clinical milestones associated with the Phase II trial in AD. Closing enrollment to screening of patients in the Phase II AD trial was announced at the end of the third quarter of 2024. Approximately seven months after the last patient is enrolled into AD02, top line cognition data with EMACC and CDR will be available. Secondary endpoints which include blood biomarker, neuroimaging and additional neuropsychiatric endpoints will be available after data-base lock 2-3 months after top line data. Finally, several months after all the data are analyzed, the Company plans an end-of-phase II meeting with the FDA to finalize plans for the pivotal Phase III trial. XPro for treatment of AD may be eligible for one or both accelerated approval pathways. The Company plans to apply for an accelerated pathway and plans to submit of Fast Track status. We expect to be eligible for Break Through status after completion of the Phase II trial in 2025.

Effective therapy for TRD is a large unmet need. Twenty percent of patients with Major Depressive Disorder have TRD. Once third of TRD patients have peripheral biomarkers to inflammation (elevated CRP) – the target population of the TRD program. 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 end-points include both clinical and neuroimaging measures. The final trial design is ongoing and discussions with the FDA are not complete. The Company expects to receive authorization to initiate a clinical trial in TRD during the second half of 2024. The TRD trial is expected to start enrollment after the AD Phase II trial finishes patient enrollment.

Our data show 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 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 that remains after conventional treatment. We have in vitro data suggesting that INKmune can be used to treat numerous hematologic malignancies and solid tumors including leukemia, multiple myeloma, lymphoma, lung, ovary, breast, renal and prostate cancer. The Company had a Phase I trial using INKmune to treat patients with high risk MDS/AML, a form of leukemia. Two patients were treated in the Phase I trial for MDS, three patients have been treated compassionately in AML. During March 2024, the Company decided to terminate further enrollment in the MDS/AML trial due to recruitment difficulties in the European trial sites. However, in the patients who were treated, INKmune therapy was shown to be safe, and induced development of cancer killing memory-like NK cells that were found in the patient’s circulation for up to 4 months. The Company initiated a separate Phase I/2 trial of INKmune in a metastatic castrate resistant prostate cancer in 8 trials sites across the US. The open label trial enrolled the first patient in December 2023, opened the second cohort in June 2024, and expects to open the third cohort to patient enrollment in November 2024.

The Phase I/II trial using INKmune™ to treat patients with metastatic castrate resistant prostate cancer (mCPRC) is an open label trial. Biomarker data from the patients will be visible as patients are treated. The Company will report data from each cohort as it becomes available. In addition to clinical data, the Company will communicate when the Phase I portion of the trial has completed follow-up. The limited immunologic data was reported from the low dose Phase I cohort during the third quarter of 2024 and showed an increase in functional memory like NK cells in the patient’s circulation. Because of the modified Bayesian design, the Company estimates trial enrollment will be completed during the first half of 2025 with top-line data available 6 months later. Topline data are divided into immunologic and tumor response variables. The most important immunologic response variable is related to memory like NK cell persistence. Persistence is how long are the number of mlNK cells in patients’ blood compared to baseline. There are 3 important variables to tumor response: i) blood PSA changes; ii) change in PMSA scan and iii) change in circulating tumor DNA (ctDNA). Ideally, the levels of all three variables decrease with treatment, but, in this patient group with advanced disease, absence of progression will be a notable achievement. We do not expect this 6-month trial to provide survival data.

We continue to look for ways to utilize our unique manufacturing and biologic capabilities to optimize clinical application of cell therapies. We believe that we have developed a way to manufacture human mesenchymal stromal cells for the medical research and biotech community that offers large volumes of high-quality, low passage human umbilical cord mesenchymal stromal cells with minimal batch-to-batch variability. We have established a reliable supply of human umbilical cords based on our agreement with the Anthony Nolan Cord Blood Bank in the United Kingdom and may seek additional supplies from US sources in the future. We have developed a validated manufacturing process that reliably produces clinical grade (“cGMP”) quality mesenchymal stromal cells that we call CORDstrom. The manufacturing process is currently performed at a contract manufacturing site under the direction of Mark Lowdell, the Company’s CSO. To date, we are supporting a multicenter academic clinical trial in the UK with CORDstrom. This is a Phase I/IIb trial sponsored by the Great Ormond Street Children’s Hospital in London treating children with the most severe form of Epidermolysis Bullosa (“EB”), a disfiguring and sometimes fatal skin disease that is similar to a second-degree burn. INmune Bio is supplying the clinical product for treatment of these patients. We have identified contract manufacturers in the UK that have the capability to produce cGMP stem cells. We expect the commercial arrangement with academic laboratories or biopharma companies to be a combination of fee-for-service and licensing that does not require additional investment by us. We will be opportunistic in pursuing therapeutic opportunities for our own portfolio with this platform in the future if resources become available. The regulatory path for therapeutic applications of the mesenchymal stem cell products is well established and similar to the regulatory approval process for other cell therapies. We will only be responsible for regulatory compliance related to manufacturing of the mesenchymal stromal cells when the product is being developed by a third party. When developing a therapeutic product for the Company’s commercial portfolio, the Company will be responsible for all aspects of the regulatory process.

We continue to incur significant development and other expenses related to our ongoing operations. As a result, we are not and have never been profitable and have incurred losses in each period since our inception, resulting in substantial doubt in our ability to continue as a going concern. We reported a net loss of $32.9 million for the nine months ended September 30, 2024. As of September 30, 2024 and December 31, 2023, we had cash and cash equivalents of $33.6 million and $35.8 million, respectively. We expect to continue to incur significant losses for the foreseeable future, and we expect these losses to increase as we continue our research and development of, and seek regulatory approvals for, our product candidates. The size of our future net losses will depend, in part, on the rate of future growth of our expenses and our ability to generate revenues, if any.

Our recurring net losses and negative cash flows from operations raised substantial doubt regarding our ability to continue as a going concern within one year after the issuance of our unaudited condensed consolidated financial statements for the nine months ended September 30, 2024. Until we can generate sufficient revenue from the commercialization of our product candidates, we expect to finance our operations through the public or private sale of equity, debt financings or other capital sources, such as government funding, collaborations, strategic alliances, divestment of non-core assets, or licensing arrangements with third parties. To date, the Company has relied on equity and debt financing to fund its operations.

As a company with less than $1.235 billion in revenue during our last fiscal year, we qualify as an “emerging growth company” under the JOBS Act. As an emerging growth company, we may take advantage of specified reduced disclosure and other requirements that are otherwise applicable generally to public companies. These provisions include:

We have elected to take advantage of the above-referenced exemptions and we may take advantage of these exemptions for up to five years or such earlier time that we are no longer an emerging growth company. We would cease to be an emerging growth company if we have more than $1.235 billion in annual revenues, we have more than $700 million in market value of our stock held by non-affiliates, or we issue more than $1 billion of non-convertible debt over a three-year period. We may choose to take advantage of some but not all of these reduced burdens.

Research and Development

Research and development expense consists of expenses incurred while performing research and development activities to discover and develop our product candidates. This includes conducting preclinical studies and clinical trials, manufacturing development efforts and activities related to regulatory filings for product candidates. We recognize research and development expenses as they are incurred. Our research and development expense primarily consist of:

The following table summarizes our research and development expenses by product candidate for the periods indicated (in thousands):

We typically use our employee resources across our development programs. We track outsourced development costs by product candidate or development program, but we do not allocate internal costs personnel costs including salaries and stock-based compensation to specific product candidates or development programs.

We participate, through our wholly owned subsidiary in Australia, in the Australian research and development tax incentive program, such that a percentage of our qualifying research and development expenditures are reimbursed by the Australian government, and such incentives are reflected as a reduction of research and development expense. The Australian research and development tax incentive is recognized when there is reasonable assurance that the incentive will be received, the relevant expenditure has been incurred and the amount of the consideration can be reliably measured.

We participate, through our wholly owned subsidiary in the United Kingdom, in the research and development program provided by the United Kingdom tax relief program, such that a percentage of our qualifying research and development expenditures are reimbursed by the United Kingdom government, and such incentives are reflected as a reduction of research and development expense. The United Kingdom research and development tax incentive is recognized when there is reasonable assurance that the incentive will be received, the relevant expenditure has been incurred and the amount of the consideration can be reliably measured.

Substantially all our research and development expenses to date have been incurred in connection with our current and future product candidates. We expect our research and development expenses to increase significantly for the foreseeable future as we advance an increased number of our product candidates through clinical development, including the conduct of our planned clinical trials and manufacturing drug to be used in those clinical trials. The process of conducting clinical trials necessary to obtain regulatory approval is costly and time consuming. The successful development of product candidates is highly uncertain. At this time, we cannot reasonably estimate the nature, timing or costs required to complete the remaining development of any product candidates. This is due to the numerous risks and uncertainties associated with the development of product candidates. 

The costs of clinical trials may vary significantly over the life of a project owing to, but not limited to, the following:

We do not expect any of our product candidates to be commercially available for at least the next several years, if ever. We expect to continue to incur significant expenses and increasing operating losses for the foreseeable future, which may fluctuate significantly from quarter-to-quarter and year-to-year. We anticipate that our expenses will increase substantially as we:

General and Administrative Expenses

General and administrative expenses consist principally of payroll and personnel expenses, including stock-based compensation; professional fees for legal, consulting, accounting and tax services; overhead, including rent and utilities; and other general operating expenses not otherwise classified as research and development expenses.

Other income (expense)

Other income (expense) consists primarily of interest expense incurred on debt and interest income on investments in money market accounts.

Results of Operations

Comparison of the Three Months Ended September 30, 2024 and 2023

The following table summarizes our results of operations for the periods indicated:

Revenues

The Company had no sales during the three months ended September 30, 2024. During the three months ended September 30, 2023, the Company sold Mesenchymal stem cells to one third-party and recognized $43,000 of revenues.  

Research and Development

Research and development expenses were approximately $10.1 million during the three months ended September 30, 2024, compared to approximately $6.0 million during the three months ended September 30, 2023. The change in research and development expenses during the three months ending September 30, 2024 compared to the three months ending September 30, 2023 is largely due to incurring $3.8 million more expenses with our Alzheimer’s clinical program due to the advancement of enrollment in the clinical trial.

General and Administrative

General and administrative expenses were approximately $2.2 and $2.6 million during the three months ended September 30, 2024 and 2023, respectively. The decrease in general and administrative expenses was mainly due to the Company incurring $0.3 million lower consulting expenses in 2024. 

Other Income (Expense), net

The Company’s other income, net is higher during the three months ended September 30, 2024, due to the Company earning interest income on its money market accounts and incurring less interest expense compared to 2023 due to a reduction in the amount of debt owed.

Comparison of the Nine Months Ended September 30, 2024 and 2023

The following table summarizes our results of operations for the periods indicated:

Revenues

During the nine months ended September 30, 2024, and 2023, the Company sold Mesenchymal stem cells to one third-party and recognized $14,000 and $127,000, respectively, of revenues.

Research and Development

Research and development expenses were approximately $25.8 million and $14.3 million during the nine months ended September 30, 2024 and 2023, respectively. The change in research and development expenses during the nine months ending September 30, 2024 compared to the nine months ending September 30, 2023 is mainly due to the advancement of our clinical trials which include incurring $10.3 million of higher expenses with our Alzheimer’s clinical program as a result of higher enrollment, $1.8 million of higher expenses with our INKmune clinical programs as a result of progress in our metastatic castration-resistant prostate cancer clinical trial and 0.7 million higher salaries and stock-based compensation, partially offset by a $1.0 million increase in our accrued research and development rebate accrual. 

General and Administrative

General and administrative expenses were approximately $7.4 million and $7.2 million during the nine months ended September 30, 2024 and 2023, respectively. The $0.2 million increase in general and administrative expenses was mainly due to higher compensation expense in 2024.

Other Income (Expense), net

The Company’s other income, net is higher during the nine months ended September 30, 2024, due to the Company earning interest income on its money market accounts and incurring less interest expense compared to 2024 due to a reduction in the amount of debt owed.

Liquidity and Capital Resources

Liquidity is the ability of a company to generate funds to support its current and future operations, satisfy its obligations and otherwise operate on an ongoing basis.

We incurred a net loss of $32.9 million and $21.6 million for the nine months ended September 30, 2024 and 2023, respectively. Net cash used in operating activities was $22,348,000 and $8,579,000 for the nine months ended September 30, 2024 and 2023, respectively. Since inception, we have funded our operations primarily with proceeds from the sales of our common stock and warrants. As of September 30, 2024, we had cash and cash equivalents of $33,552,000. We anticipate that operating losses and net cash used in operating activities will increase over the next few years as we advance our products under development.

During the nine months ending September 30, 2024, the Company sold 247,126 shares of common stock at an average price of $9.85 for gross proceeds of approximately $2.4 million under the at the market offerings.

During September 2024, the Company entered into securities purchase agreements with investors whereby the Company sold 2,341,260 shares of the Company’s common stock and warrants to purchase an additional 2,341,260 shares of the Company’s common stock exercisable six months from the issuance date in a registered direct offering in exchange for gross proceeds of $13.0 million (net proceeds of approximately $12.0 million). Directors and officers that participated in the offering paid a combined offering price of $6.50 per share and warrant, and other investors paid $5.50 per share and warrant. The exercise price of the warrants is $6.40, and are exercisable beginning on March 16, 2025 and will terminate on March 16, 2030 unless accelerated pursuant to the terms of the warrant agreements.

On April 24, 2024, the Company entered into a securities purchase agreement with an investor in which the Company sold 986,000 shares of common stock and warrants to purchase 986,000 shares of common stock for gross proceeds of approximately $9.7 million (net proceeds of approximately $8.9 million). The exercise price of the warrants is $9.84, and the term is the earlier of two years from the issuance of the warrants and thirty trading days following the release of top line data in the Phase 2 Alzheimer’s program.

On April 19, 2024, the Company entered into securities purchase agreements with purchasers in which the Company sold 571,592 shares of common stock and warrants to purchase 571,592 shares of common stock for aggregate gross proceeds of approximately $4.8 million (net proceeds of approximately $4.5 million). The exercise price of the warrants is $9.152, and the term is the earlier of two years from the issuance of the warrants and thirty trading days following the release of top line data in the Phase 2 Alzheimer’s program, provided that directors and officers of the Company that are subject to a blackout with respect to trading in the Company’s stock will have an additional 60 days from the termination of the blackout date to exercise the warrant. Directors and officers that participated in the offering paid a combined offering price of $8.445 per share and warrant, and other investors paid $8.32 per share and warrant.

Our primary uses of capital are, and we expect will continue to be, third-party clinical and preclinical research and development services, costs incurred to manufacture our drugs under development, compensation and related expenses, legal, patent and other regulatory expenses and general overhead costs. We believe our use of CROs provides us with flexibility in managing our spending.

The Company incurs significant research and development expenses in Australia and the United Kingdom. Fluctuations in the rate of exchange between the United States dollar and the pound sterling as well as the Australian dollar could adversely affect our financial results, including our expenses as well as assets and liabilities. We currently do not hedge foreign currencies but will continue to assess whether that strategy is appropriate. As of September 30, 2024, the cash balance held by our foreign subsidiaries with currencies other than the United States dollar was approximately $0.9 million.

Our recurring net losses and negative cash flows from operations, as well as forecast of continued losses and negative cash flows from operations, raised substantial doubt regarding our ability to continue as a going concern within one year after the issuance of our unaudited condensed consolidated financial statements for the year ended September 30, 2024. Until we can generate sufficient revenue from the commercialization of our product candidates, we expect to finance our operations through the public or private sale of equity, debt financing or other capital sources, such as government funding, collaborations, strategic alliances, divestment of non-core assets, or licensing arrangements with third parties. Our cash and cash equivalents were $33.6 million and total current assets were $35.9 million at September 30, 2024, which the Company is projecting will be insufficient to sustain its operations through one year following the date that the financial statements are issued.

Additional capital may not be available on reasonable terms, if at all. If we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may have to significantly delay, scale back or discontinue the development of one or more of our product candidates or cease operations. If we raise additional funds through the issuance of additional debt or equity securities it could result in dilution to our existing stockholders, increased fixed payment obligations and these securities may have rights senior to those of our common stock and could contain covenants that would restrict our operations and potentially impair our competitiveness, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license our intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. Any of these events could significantly harm our business, financial condition and prospects.

Financing strategies we may pursue include, but are not limited to, the public or private sale of equity, debt financing or funds from other capital sources, such as government or grant funding, collaborations, strategic alliances, divestment of non-core assets, or licensing arrangements with third parties. There can be no assurances additional capital will be available to secure additional financing, or if available, that it will be sufficient to meet our needs on favorable terms. If we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may have to significantly delay, scale back or discontinue the development of one or more of our product candidates. If we raise additional funds through the public or private sale of equity or debt financings, it could result in dilution to our existing stockholders or increased fixed payment obligations and these securities may have rights senior to those of our common stock and could contain covenants that would restrict our operations and potentially impair our competitiveness, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license our intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. Any of these events could significantly harm our business, financial condition and prospects.

Cash Flows

The following table summarizes our cash flows for the periods indicated:

Operating Activities

Our cash used in operating activities was primarily driven by our net loss.

Operating activities used approximately $22.3 million of cash during the nine months ended September 30, 2024, resulting from our loss of $32.9 million, partially offset by changes in our net operating assets and liabilities of $4.6 million and non-cash stock-based compensation of $5.8 million. The change in our net operating assets and liabilities was mainly due to an increase in accounts payable and accrued liabilities of $2.7 million, a decrease in research and development tax receivable of $0.8 million, a decrease in prepaid expenses of $0.6 million and a decrease in other tax receivable of $0.2 million.

Operating activities used approximately $8.6 million of cash during the nine months ended September 30, 2023, resulting from our loss of $21.6 million, partially offset by changes in our net operating assets and liabilities of $7.4 million and non-cash stock-based compensation of $5.5 million. The change in our net operating assets and liabilities was mainly due to a decrease in research and development tax credit receivable of $6.0 million and a decrease in prepaid expenses of $2.5 million, partially offset by a decrease in accounts payable and accrued liabilities of $1.5 million.  

Financing Activities

During the nine months ended September 30, 2024, the Company sold 247,126 shares of its common stock under its ATM programs for net proceeds of approximately $2.4 million.

During the nine months ended September 30, 2024, the Company sold 3,898,852 shares of its common stock and 3,898,852 warrants to purchase its common stock in registered direct offerings for net proceeds of approximately $25.4 million.

During the nine months ended September 30, 2023, the Company sold 75,697 shares of its common stock for net proceeds of $775,000 under the Company’s ATM program with BTIG.

During the nine months ended September 30, 2024 and 2023, the Company repaid $7.5 and $2.5 million, respectively, of its debt.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations is based upon our unaudited consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States, or GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses. Actual results may differ from these estimates. Our critical accounting policies and estimates are discussed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, and there have been no material changes during the nine months ended September 30, 2024.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) at the end of the period covered by this quarterly report.

Based on this evaluation, we concluded that, as of such date, our disclosure controls and procedures were effective to provide reasonable assurance that the information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

We recognize that any controls system, no matter how well designed and operated, can provide only reasonable assurance of achieving its objectives, and our management necessarily applies its judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the period covered by this quarterly report that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act).
