GeoVax Reports 2022 Year-End Financial Results and Provides Corporate Update

Company Expands Ongoing Clinical Trials and the
Breadth and Capacity of Its Novel Vaccine Platform Technology

ATLANTA, GA, March 23, 2023 (GLOBE NEWSWIRE) — via NewMediaWire – GeoVax Labs, Inc. (Nasdaq: GOVX), a biotechnology company developing immunotherapies and vaccines against cancers and infectious diseases, today announced its financial results and key operational accomplishments for the year ended December 31, 2022.

GeoVax’s leadership will host a live conference call and webcast at 4:30 p.m. Eastern Time today, March 23, 2023, to discuss financial results and provide a general business update. Details are provided below.

2022 CLINICAL TRIAL PROGRESS AND OPERATIONAL DEVELOPMENTS

“Our corporate focus continues to be on the advancement of our ongoing clinical programs for our novel Gedeptin^® cancer therapy targeting advanced head & neck cancers and, our SARS-CoV-2/Covid19 vaccine, stated David Dodd, GeoVax’s Chairman and CEO. “To that end, we have expanded to additional clinical sites and are accelerating patient enrollment for both programs, as noted in this update. We look forward to reporting milestone progress on these trials during the remainder of 2023.”

Dodd continued, “We are also delighted to have advanced our GeoVax MVA-VLP-MUC1 immuno-oncology candidate into IND-supportive studies. Thus far, the results from these studies are encouraging. We also secured rights to NIH-MVA technology for further development and commercial use against Monkeypox (MPox) and Smallpox 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 intent is to be the first U.S.-based, primary supplier of a MVA-vaccine against Mpox and Smallpox.”

Dodd concluded, “We recently announced important progress toward developing a high-yield, high-capacity, avian cell line system for manufacturing MVA-based vaccines. Developing such a process will be nothing short of transformational – for GeoVax, biomedicine, and public health worldwide. By advancing our MVA manufacturing to a modern, interchangeable process, we are on course to expand MVA applications from stockpile-based solutions for niche medical markets to have the capability to respond to world needs on a timely basis. This well positions us to potentially become the first US-based supplier of the MVA vaccine to prevent MPox, Smallpox, and other pox-related viruses. Finally, during a very difficult year for biotech capital development, with many companies furloughing programs and staff, GeoVax successfully strengthened our capital base in support of expanding and accelerating our growth and development programs. We have entered 2023 well positioned and capable of achieving our clinical and other business goals and milestones.”

GEDEPTIN^® FOR ADVANCED HEAD AND NECK CANCER – PHASE 2 TRIAL EXPANSION

An ongoing Phase 1/2 trial (ClinicalTrials.gov Identifier: NCT03754933) is evaluating the safety and efficacy of repeat cycles of Gedeptin^® therapy in patients with recurrent head and neck squamous cell carcinoma (HNSCC), with tumor(s) accessible for injection and no curable treatment options.

Gedeptin^® is a novel patented product/technology for the treatment of solid tumors through a gene therapy strategy known as Gene-Directed Enzyme Prodrug Therapy (GDEPT). In GDEPT, a vector is used to selectively transduce tumor cells with a nonhuman gene, which expresses an enzyme that can convert a nontoxic prodrug into a very toxic antitumor compound in situ. A Phase 1 dose-ranging study, evaluating the safety of a single cycle of Gedeptin^® therapy, found the therapy well-tolerated, with evidence of a reduction in tumor size in patients with solid tumors.

In February 2023, GeoVax announced the expansion of the Gedeptin^® Phase 1/2 trial with patients actively enrolling at National Cancer Institute (NCI) designated Cancer Centers – Stanford University Cancer Institute, Emory University Winship Cancer Institute, and the Thomas Jefferson University Sidney Kimmel Cancer Center. Funded in part by the US Food & Drug Administration (FDA) 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. Additionally, it may lead to labeling discussions with the FDA and initiation of further Gedeptin^® investigations, including in combination with immune checkpoint inhibitors for other cancerous and non-cancerous tumor indications.

SARS-CoV-2 VACCINES – TWO PHASE 2 CLINICAL TRIALS PROGRESSING

GEO-CM04S1 is a next-generation Covid-19 vaccine that expresses spike and nucleocapsid antigens of the SARS-CoV-2 (COVID-19) virus. GEO-CM04S1 continues to advance in two Phase 2 clinical studies, one as a primary vaccine for immunocompromised cancer patients, in direct comparison to either the Pfizer or Moderna mRNA vaccine (ClinicalTrials.gov Identifier: NCT04977024), and the second as a booster for healthy patients who have previously received either the Pfizer or Moderna vaccine as their initial inoculation (ClinicalTrials.gov Identifier: NCT04639466).

Two 2022 peer-reviewed publications in The Lancet Microbe (accessible here) and iScience (accessible here) report data from the Phase 1 study of GEO-CM04S1 showing robust neutralizing antibodies and T cells against SARS-CoV-2, including the Omicron and Delta variants. These data confirm the powerful dual action of the GeoVax vaccine, an important feature given the multiple mutations, leading to variants of concern and inconsistent protection from existing FDA-authorized vaccines. 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 among the population in general as well as among the 15 million patients in the US with compromised immune systems.   Additionally, a recent article, published in the New England Journal of Medicine (accessible here) addressed the critical importance of addressing both antibodies and T cells in achieving protection against SARS-CoV-2.

MODIFIED VACCINIA ANKARA (MVA) & MONKEYPOX (MPOX)

MVA is the vaccine currently used and stockpiled in the US Strategic National Stockpile for immunization against the MPox and Smallpox viruses. 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 MPox virus (publication accessible here). Further, in August 2022, City of Hope, which originally developed GEO-CM04S1, published results demonstrating that both their proprietary sMVA (synthetic MVA) and GEO-CM04S1 (referred to as “COH04S1” in the publication, accessible here) elicited robust orthopoxvirus-specific binding and neutralizing antibody responses. The authors conclude that GEO-CM04S1 and sMVA represent unique vaccine candidates to control the unforeseen global MPox outbreak.

In response to the global need to address the continued emerging threat from MPox and the unique opportunity offered by MVA-based vaccines, GeoVax secured rights from the NIH covering preclinical, clinical and commercial uses of the NIH-MVA against MPox or Smallpox viruses. The Company is now evaluating development and regulatory pathways towards expanding the public health options available to reduce and manage the risk of MPox worldwide with the intent to be the first U.S.-based supplier of a MVA-vaccine against MPox and Smallpox.  

MVA MANUFACTURING PROCESS DEVELOPMENTS

In February 2023, GeoVax announced significant progress in developing a high-yield, high-capacity, continuous avian cell line system for manufacturing its MVA-based vaccines and immunotherapies. Currently, MVA vaccines are manufactured in cells cultured from chicken embryonic fibroblasts (CEF), a suboptimal and time-consuming process useful primarily for niche markets and stockpile reserves. Now, after exploring various approaches to growing MVA in continuous cell lines in bioreactors more suitable for high-yield, commercial-scale manufacturing, GeoVax will accelerate activities towards fully implementing a proprietary, continuous cell line manufacturing system that will provide lower-cost, scalable versatility for broad MVA vaccine and immunotherapy applications.

OTHER NOTABLE DEVELOPMENTS

In July 2022, GeoVax announced the publication of a peer-reviewed animal efficacy study of its 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.

In January 2023, GeoVax announced that the US Patent and Trademark Office issued a Notice of Allowance for Patent Application No. 17/000,768 titled, “Method for Generating a ZIKV Immune Response Utilizing a Recombinant Modified Vaccinia Ankara Vector Encoding the NS1 Protein.” Preclinical studies demonstrated that a single dose of GEO-ZM02 provided 100% protection against a lethal dose of the Zika virus.

LEADERSHIP AND CAPITAL RESOURCES STRENGTHENED

During 2022, GeoVax strengthened its organizational and operational leadership team with appointments to several areas, including Kelly T. McKee, Jr., M.D., M.P.H. as Chief Medical Officer; Jeffrey Welch as Head, Process Development and Manufacturing Operations; John W. Sharkey, Ph.D. as Vice President, Business Development; Mark J. Newman, Ph.D. as full-time Chief Scientific Officer; the appointment of two new members to the GeoVax Board of Directors – Nicole Lemerond and Jayne Morgan, M.D.; and the appointment of Valerie Montgomery Rice, M.D., FACOG, President and CEO of Morehouse School of Medicine, to serve as a special advisor to the GeoVax Board of Directors.

During 2022, GeoVax added to its cash resources through offerings of common stock and exercises of warrants with combined net proceeds of approximately $35.4 million. GeoVax’s cash balances at December 31, 2022 stood at $27.6 million.

FINANCIAL REVIEW

Net loss for the year ended December 31, 2022, was $14.0 million, as compared to $18.6 million for the year ended December 31, 2021.

Research and development (R&D) expenses were $9.1 million for 2022, as compared to $15.6 million in 2021. Research and development expense for 2021 includes $12.3 million of one-time license fees and other costs related to technology licensing agreements; excluding these costs, research and development expense increased by $5.9 million from 2021 to 2022. The increase during 2022 relates primarily to higher personnel and consulting costs, costs of conducting clinical trials for GEO-CM04S1 and Gedeptin, costs of manufacturing materials for use in clinical trials, and a generally higher level of activity.

General and administrative expenses were $5.0 million for 2022, as compared to $3.6 million in 2021, with the increase primarily attributable to higher personnel and consulting costs, patent costs, investor relations costs, and travel expenses.

GeoVax reported cash balances of $27.6 million at December 31, 2022, as compared to $11.4 million at December 31, 2021. Contributing to the increase in cash balances were aggregate net proceeds of $27.7 million from equity transactions during January and May 2022, and $7.6 million from the exercise of warrants during August 2022.
