Overview
GeoVax is a clinical-stage biotechnology company developing immunotherapies and vaccines against infectious diseases and cancers using novel vector vaccine platforms. GeoVax’s product pipeline includes ongoing human clinical trials in COVID-19 and head and neck cancer. Additional research and development programs include preventive vaccines against Zika Virus, hemorrhagic fever viruses (Ebola, Sudan, Marburg, and Lassa) and malaria, as well as immunotherapies for solid tumors.
Our programs are in various stages of development, the most significant of which are summarized below:
●
|
GEO-CM04S1 is currently undergoing a Phase 2 clinical trial (NCT04977024), evaluating its safety and efficacy as a preventive COVID-19 vaccine in patients who have previously received either an allogeneic hematopoietic cell transplant, an autologous hematopoietic cell transplant or chimeric antigen receptor (CAR) T cell therapy. GEO-CM04S1 is the only COVID-19 vaccine that includes both SARS-CoV-2 spike and nucleocapsid proteins to advance to a Phase 2 trial in cancer patients. The trial is also the first to compare an investigational multi-antigenic COVID-19 vaccine to the current Food and Drug Administration (FDA)-approved mRNA vaccine from Pfizer/BioNTech in people who are immunocompromised.
|
●
|
GEO-CM04S1 is also undergoing the Phase 2 portion of a Phase 1/2 trial (NCT04639466), evaluating its use as a universal booster vaccine to current FDA-approved two-shot mRNA vaccines from Pfizer/BioNTech and Moderna.
|
●
|
Gedeptin® is currently undergoing a Phase 1/2 clinical trial (NCT03754933) for treatment of patients with recurrent head and neck squamous cell carcinoma (HNSCC). The initial stage of this trial is being conducted with funding support from the U.S. Food & Drug Administration (FDA) pursuant to its Orphan Products Clinical Trials Grants Program.
|
●
|
GEO-CM02 (our pan coronavirus vaccine) has shown promising results in preclinical studies to date and we have recently initiated additional studies to prepare for IND (Investigational New Drug) filing and subsequent human clinical trials.
|
●
|
Our research program for treatment of solid tumors (MVA-VLP-MUC1) is progressing with additional preclinical studies recently initiated. The initial animal studies of our MVA-VLP-MUC1 vaccine and ICI combination, have been encouraging, showing that a combination of our MVA-VLP-MUC1 vaccine candidate with a MUC1 synthetic peptide was capable of breaking tolerance to human MUC1 in transgenic mice and inducing immune responses with efficacy against challenge in a lymphoma tumor model. Our studies also demonstrated a significant reduction of the tumor burden in a mouse model for colorectal cancer. We have initiated animal studies to determine the optimal course and schedule of vaccination to define a protocol that can be evaluated in a Phase 1 clinical trial.
|
●
|
Our additional research programs for vaccines against Zika virus, malaria and hemorrhagic fever viruses are at various stages of preclinical development.
|
Financial Overview
Revenues
Our grant revenues relate to grants and contracts from agencies of the U.S. government in support of our vaccine development activities. We record revenue associated with these grants as the related costs and expenses are incurred. We have not generated any revenues from product sales to date. Our product candidates will require significant additional research and development efforts, including extensive preclinical and clinical testing. All product candidates that we advance to clinical testing will require regulatory approval prior to commercial use and will require significant costs for commercialization.
Research and development expenses
Since our inception, we have focused and we continue to focus significant resources on our research and development activities, including developing our vector platform and analytical testing methods, conducting preclinical studies, developing manufacturing processes, and conducting clinical trials. Research and development costs are expensed as incurred and consist primarily of the following:
●
|
personnel costs in our research, development and regulatory functions, which include salaries, benefits and stock-based compensation;
|
●
|
expenses incurred under agreements with contract research organizations (“CROs”), that conduct clinical trials on our behalf;
|
●
|
expenses incurred under agreements with contract manufacturing organizations (“CMOs”), that manufacture product used in the clinical trials;
|
●
|
expenses incurred in procuring materials and for analytical and release testing services required to produce vaccine candidates used in clinical trials;
|
●
|
process development expenses incurred internally and externally to improve the efficiency and yield of the bulk vaccine;
|
●
|
laboratory supplies, vendor expenses and other third-party contract expenses related to preclinical research activities;
|
●
|
technology license fees;
|
●
|
consultant expenses for services supporting our clinical, regulatory and manufacturing activities; and
|
●
|
facilities, depreciation and other general overhead expenses.
|
We track our external research and development costs on a program-by-program basis. We do not track our internal research and development expenses on a program-by-program basis as they primarily relate to shared costs deployed across multiple projects under development.
Our research and development expenses can fluctuate considerably on a period-to-period basis. We expect our research and development expenses to increase substantially in the future as we advance our existing and future product candidates into and through clinical trials and pursue regulatory approval. The process of conducting the necessary clinical studies to obtain regulatory approval is costly and time-consuming. Clinical trials generally become larger and more costly to conduct as they advance into later stages.
At this time, we cannot reasonably estimate or know the nature, timing and estimated costs of the efforts that will be necessary to complete the development of any product candidates that we develop from our programs. We are also unable to predict when, if ever, material net cash inflows will commence from sales of product candidates we develop, if at all. This is due to the numerous risks and uncertainties associated with developing product candidates.
General and administrative expenses
Our general and administrative expenses consist primarily of personnel costs in our executive, finance and investor relations, business development and administrative functions, including stock-based compensation. Other general and administrative expenses include consulting fees, professional service fees for accounting and legal services, lease expenses related to our offices, insurance premiums, intellectual property costs incurred in connection with filing and prosecuting patent applications, depreciation and other costs. We expect our general and administrative expenses to continue to increase in the future as we expand our operating activities and prepare for potential commercialization of our current and future product candidates, increase our headcount and investor relations activities and maintain compliance with requirements of Nasdaq and the Securities and Exchange Commission.
Critical Accounting Policies and Estimates
This discussion and analysis of our financial condition and results of operations is based on our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, management evaluates its estimates and adjusts the estimates as necessary. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates under different assumptions or conditions.
For a description of critical accounting policies that require significant judgments and estimates during the preparation of our financial statements, refer to Item 7 in Management’s Discussion and Analysis of Financial Condition and Results of Operations and Note 2 to our Consolidated Financial Statements contained in our Annual Report on Form 10-K for the year ended December 31, 2021. There have been no significant changes to our critical accounting policies from those disclosed in our 2021 Annual Report.
Information regarding recent accounting pronouncements is contained in Note 2 to the condensed consolidated financial statements, included in this Quarterly Report.
Off-Balance Sheet Arrangements
We have no off-balance sheet arrangements that are likely or reasonably likely to have a material effect on our financial condition or results of operations, other than the operating lease for our office and laboratory space.

Total grant revenues decreased by $79,708 (100%) for the three-month period ended June 30, 2022 and by $108,599 (57%) for the six-month period ended June 30, 2022, versus the comparable 2021 periods, attributable to the differing mix of active grants as shown in the table above, as well as the timing of expenditures related to such grants. As of June 30, 2022, all grant funds approved for direct use by GeoVax have been utilized.
Research and Development Expenses
For the three-month and six-month periods ending June 30, 2022, research and development expenses increased by $474,342 (57%) and $1,202,103 (84%), respectively, versus the comparable 2021 periods. The overall increase during the 2022 periods relates primarily to higher personnel costs (including the use of external consultants), costs of conducting clinical trials for GEO-CM04S1 and Gedeptin, costs of manufacturing materials for use in our clinical trials, and a generally higher level of activity. Research and development expense for the three-month and six-month periods of 2022 included stock-based compensation expense of $54,293 and $108,585, respectively; as compared to $21,468 and $42,936, respectively, for the comparable 2021 periods.
General and Administrative Expenses
For the three-month and six-month periods ending June 30, 2022, general and administrative expenses increased by $201,812 (28%) and $309,126 (17%), respectively, versus the comparable 2021 periods. The overall increase during the 2022 periods relates primarily to higher personnel costs (including the use of external consultants), patent costs and travel expenses. General and administrative expense for the three-month and six-month periods of 2022 included stock-based compensation expense of $152,885 and $303,744, respectively; as compared to $65,295 and $120,617, respectively, for the comparable periods of 2021.
Other Income (Expense)
Interest income for the three-month and six-month periods ended June 30, 2022 was $789 and $1,316, respectively, as compared to $1,068 and $3,121, respectively, for comparable periods of 2021. The variances between periods are primarily attributable to cash available for investment and interest rate fluctuations.
No interest expense was recorded during the three-month and six-month periods ended June 30, 2022. Interest expense for the three-month and six-month periods ended June 30, 2021 was $531 and $1,286, respectively.
During the three-month and six-month periods ended June 30, 2021, we recorded a $172,056 one-time gain on debt extinguishment associated with the forgiveness of the principal and accrued interest related to our Paycheck Protection Program (PPP) loan.

Operating Activities – Net cash used in operating activities of $8,166,818 for the six months ended June 30, 2022, was primarily due to our net loss of $4,669,214, as adjusted by non-cash items such as depreciation expense and stock-based compensation expense, and by changes in our working capital accounts. Net cash used in operating activities of $2,879,566 for the six months ended June 30, 2021, was primarily due to our net loss of $2,876,811, also adjusted by non-cash charges such as depreciation and stock-based compensation expense, and by changes in our working capital accounts.
Investing Activities – Net cash used in investing activities was $82,383 and $19,929 for the six-month periods ended June 30, 2022 and 2021, respectively, and relates primarily to purchases of laboratory equipment.
Financing Activities – Net cash provided by financing activities was $27,727,785 for the six-month period ended June 30, 2022, consisting of net proceeds from a private placement of our common stock and warrants as described in Note 5 to the condensed consolidated financial statements, included in this Quarterly Report. Net cash provided by financing activities was $12,554,212 for the six-month period ended June 30, 2021, consisting primarily of (i) net proceeds of $9,408,920 from a public offering of our common stock, (ii) $3,174,156 of net proceeds from the exercise of warrants, and (iii) $27,864 in principal repayments in retirement of a note payable.
Funding Requirements
We have no products approved for commercial sale. We do not expect to generate any meaningful revenue unless and until we obtain regulatory approval of and commercialize our product candidates. We do not know when, or if, this will occur. As of June 30, 2022, we have an accumulated deficit of approximately $69 million and we expect to incur operating losses and generate negative cash flows from operations for the foreseeable future. We have funded our operations to date primarily from sales of our equity securities and from government grants and clinical trial assistance.
Our primary uses of capital are for personnel costs, costs of conducting clinical trials, manufacturing costs for materials used in clinical trials, third-party research services, laboratory and related supplies, technology license fees, legal and other regulatory expenses, and general overhead costs. We expect these costs will continue to be the primary operating capital requirements for the near future.
Our future expenditures are likely to be highly volatile in future periods depending on the outcomes of our clinical trials and preclinical studies. We expect our research and development costs to increase as we continue development of our various programs and as we move toward later stages of development, especially with regard to the ongoing clinical trials for Gedeptin and CEO-CM04S1. We expect our general and administrative expenses to increase commensurately in support of expanded research and development efforts.
As of the date of this Quarterly Report, we expect our existing cash and cash equivalents will be sufficient to fund our operations over at least the next twelve months.
We have based our projections of operating capital requirements on assumptions that may prove to be incorrect, and we may use our available capital resources sooner than we expect. Our future capital requirements will depend on many factors, which include but are not limited to:
●
|
the timing and costs of our ongoing and planned clinical trials;
|
●
|
the timing and costs of manufacturing material for use in clinical trials;
|
●
|
the number and scope of our research programs and the speed at which they are advanced;
|
●
|
the progress and success of our preclinical and clinical development activities;
|
●
|
the costs involved in prosecuting and enforcing patent claims and other intellectual property rights;
|
●
|
the costs to attract and retain skilled personnel;
|
●
|
the costs to maintain and expand our infrastructure to support our operations, our product development, and planned future commercialization efforts;
|
●
|
the terms and timing of establishing and maintaining collaborations, licenses and other similar arrangements;
|
●
|
the costs associated with any products or technologies that we may in-license or acquire; and
|
●
|
the costs and timing of regulatory approvals.
|
We will need to continue to raise additional capital to support our future operating activities, including progression of our development programs, preparation for commercialization, and other operating costs. Financing strategies we may pursue include, but are not limited to, the public or private sale of equity, debt financings or funds from other capital sources, such as government funding, collaborations, strategic alliances 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.
