GeoVax Reports 2022 Third Quarter Financial Results and Provides Corporate Update

Phase 2 Clinical Trials Advance for COVID-19 and Immuno-Oncology


Company Secures Rights to NIH-MVA for Protection Against Monkeypox and Smallpox

ATLANTA, GA - (NewMediaWire) - November 09, 2022 - GeoVax Labs, Inc. (Nasdaq: GOVX), a biotechnology company developing immunotherapies and vaccines against cancers and infectious diseases, today announced its financial results for the third quarter ended September 30, 2022.

GeoVax’s management will host a live conference call and webcast at 4:30 p.m. EST on Wednesday, November 9, 2022, to provide a general business update and discuss financial results. Further details are provided below.


“Our unwavering focus is on the advancement of our GEO-CM04S1 and Gedeptin® clinical programs. To that end, we are expanding to additional clinical sites and accelerating patient enrollment for both programs,” said David Dodd, GeoVax’s Chairman and CEO. “We are also delighted that we have secured rights to the NIH-MVA for further development and commercial use against Monkeypox (MPX) and Smallpox (SPX) viruses, which provides a compelling opportunity to leverage our MVA-based vaccine expertise and help expand the global public health supply options available for this ongoing worldwide public health threat. Our successful financing activities during the year provide us with adequate resources to advance these programs, including the production of additional drug product for use in these clinical trials. We are also now well-positioned to advance the preclinical studies for our GEO-CM02 pan-coronavirus vaccine candidate and our MVA-VLP-MUC1 cancer immunotherapy program to further solidify our promising pipeline of human vaccines and immunotherapies.”


GeoVax has been focused on advancing its two Phase 2 clinical studies of GEO-CM04S1 against COVID-19, one as a primary vaccine for immunocompromised cancer patients, in direct comparison to the Pfizer mRNA vaccine (NCT04977024), and the second as a booster for healthy patients who have previously received either the Pfizer or Moderna vaccine as their initial inoculation (NCT04639466). During the November 9th Corporate Update call, GeoVax will provide a progress report on study expansion developments.

Earlier this year, data from a Phase 1 study of GEO-CM04S1 were published in the The Lancet Microbe. This peer-reviewed publication (accessible here) reports data showing that GEO-CM04S1 produced robust neutralizing antibodies and T cells against SARS-CoV-2 with no significant side effects. These data confirm the powerful dual action of the GeoVax vaccine, an important feature given the multiple spike antigen mutations, leading to variants of concern and inconsistent protection from existing FDA-approved vaccines. Should a new mutation arise in the spike antigen that interferes with antibody recognition, a person vaccinated with GEO-CM04S1 may still have substantial T-cell immunity against both the nucleocapsid and spike antigens.

In July, additional analyses of data from the Phase 1 study of GEO-CM04S1 published in the peer-reviewed journal, iScience (accessible here) show that GEO-CM04S1 demonstrated potent and equivalent T-cell cross-reactivity against Delta and Omicron variants. These findings suggest that T-cell immunity stimulated by GEO-CM04S1 may constitute a critical second line of defense to provide long-term protection against SARS-CoV-2 variants. Further details and potential implications of these findings will also be discussed on the November 9th update call.

Building on earlier findings, during the third quarter GeoVax also initiated new preclinical studies of its pan-coronavirus vaccine candidate (GEO-CM02) to prepare for an Investigational New Drug (IND) application and subsequent human clinical trials as a potential single-dose universal coronavirus vaccine.


A Phase 1/2 trial (NCT03754933) evaluating the safety and efficacy of repeat cycles of Gedeptin® therapy in patients with recurrent head and neck squamous cell carcinoma (HNSCC) has broadened from a single site at Stanford University to additional sites at Emory University and Thomas Jefferson University. Funded in part by the US Food & Drug Administration under its Orphan Products Clinical Trials Grants Program, the trial will guide the design of a larger study that also may involve patients with other anatomically accessible oral and pharyngeal cancers, including cancers of the lip, tongue, gum, floor of mouth, salivary gland and other oral cavities.

To further evaluate the Company’s additional immunotherapy candidate for solid tumors (MVA-VLP-MUC1), GeoVax recently began a preclinical study with Dr. Pinku Mukherjee at the University of North Carolina at Charlotte, to define the optimal course and schedule of vaccination for incorporation into a Phase 1 clinical protocol.


In July 2022, GeoVax announced the publication of a peer-reviewed animal efficacy study of its modified vaccinia Ankara (MVA) vectored vaccine against Sudan ebolavirus (SUDV) in Nature Partner Journals (NPJ) Vaccines (accessible here). The anticipated final stage of preclinical testing involving nonhuman primates has recently been completed and results are expected to be discussed during upcoming scientific conferences during the fourth quarter of this year.


MVA is the vaccine vector utilized by GeoVax in a number of its vaccine candidates, including those for COVID-19, various hemorrhagic fever viruses, the GeoVax MVA-VLP-MUC1 cancer immunotherapy and others.  Importantly, MVA is also the vaccine used and stockpiled for immunization against the MPX and SPX viruses.

In response to the global need to address the continued emerging threat from MPX and the unique opportunity offered by MVA-based vaccines, GeoVax recently secured rights from the NIH covering preclinical, clinical and commercial uses of the NIH-MVA against MPX or SPX viruses. The Company is now evaluating development and regulatory pathways towards expanding the public health options available to reduce and manage the risk of MPX worldwide.

GeoVax previously demonstrated that an experimental HIV vaccine, utilizing NIH-MVA as the vaccine vector, protected non-human primates challenged with a lethal dose of the MPX virus three years post vaccination (publication accessible here). In August 2022, the City of Hope team, which originally developed GEO-CM04S1, published results demonstrating that both their proprietary sMVA (synthetic MVA) and GEO-CM04S1, which utilizes sMVA as the vaccine vector, (referred to as “COH04S1” in the publication, accessible here) elicited robust orthopoxvirus-specific binding and neutralizing antibody responses. They also reported that healthy adults, vaccinated with COH04S1 at different dose levels, developed robust orthopoxvirus-specific humoral and cellular immune responses that are durable for over six months post-vaccination. The authors conclude that “COH04S1 and sMVA represent unique vaccine candidates to control the unforeseen global MPXV outbreak.”


GeoVax reported a net loss of $3,968,102 ($0.17 per share) for the three months ended September 30, 2022, compared to a net loss of $1,950,503 ($0.31 per share) for the same period in 2021. For the nine months ended September 30, 2022, the Company’s net loss was $8,637,316 ($0.63 per share) as compared to a net loss of $4,827,314 ($0.80 per share) in 2021.

Research and development expenses were $2,721,196 and $5,358,917 for the three-month and nine-month periods of 2022, respectively, as compared to $1,224,362 and $2,659,980 for the comparable periods of 2021, with the increases primarily due to higher personnel and consulting costs, costs of conducting clinical trials for GEO-CM04S1 and Gedeptin and costs of manufacturing materials for use in clinical trials.

General and administrative expenses were $1,249,337 and $3,363,672 for the three-month and nine-month periods of 2022, respectively, as compared to $757,432 and $2,562,541 for the comparable periods of 2021, with the increases primarily attributable to higher personnel costs and consulting costs, patent costs, investor relations costs and travel costs, all associated with a generally higher level of activity during 2022.

GeoVax reported cash balances of $34.7 million on September 30, 2022, as compared to $11.4 million on December 31, 2021. Contributing to the increase in cash balances during the nine-month period were aggregate net proceeds of $27.7 million from sales of our common stock and warrants during January and May, and $7.6 million from the exercise of warrants during August.

Summarized financial information is attached. Further information is included in the Company’s Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission.
