Company Advancing Phase 2 Clinical Trials for COVID-19 and Immuno-Oncology 

Atlanta, GA - (NewMediaWire) - April 27, 2022 - GeoVax Labs, Inc. (NasdaqCM: GOVX), a biotechnology company developing vaccines and immunotherapies against infectious diseases and cancers, today announced its financial results for the three months ended March 31, 2022.

GeoVax’s management will host a live conference call and webcast at 4:30 p.m. Eastern Standard Time on Wednesday, April 27 to discuss financial results and provide a general business update. Details are provided further below.

First Quarter 2022 Highlights

Phase 2 Trials – GEO-CM04S1 – GEO-CM04S1 is being studied in a first-of-its-kind Phase 2 clinical trial (NCT04977024) as a primary vaccine for immunocompromised cancer patients who have difficulty producing antibodies and largely depend on T cells to protect against the virus responsible for COVID-19. Also, GEO-CM04S1 is being evaluated in a Phase 2 vaccine booster trial format (NCT04639466), which is aimed at evaluating how GEO-CM04S1 may boost pre-existing vaccine immunity to spike while also causing a strong immune response to nucleocapsid. GEO-CM04S1 is unique to other COVID-19 vaccines in that it targets both the spike and nucleocapsid proteins. In contrast, the current U.S. Food and Drug Administration-approved COVID-19 vaccines only target the spike protein. 

In March 2022, data from a Phase 1 study of GEO-CM04S1 (formerly known as COH04S1) was published in the peer-reviewed journal, The Lancet Microbe.  The 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 mutations in spike, 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 our vaccine may still have substantial T cell immunity against both the nucleocapsid and spike antigens.

Phase 1/2 Trial – Gedeptin® – 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) that have tumor(s) accessible for injection and no curable treatment options, is ongoing at Stanford University in collaboration with Emory University. The trial design involves repeat administration using Gedeptin, followed by systemic fludarabine, to gain additional information prior to expansion towards a larger patient trial. The initial stage of the study is being funded by the FDA under its Orphan Products Clinical Trials Grants Program. The FDA has also granted Gedeptin Orphan Drug Status for the intra-tumoral treatment of anatomically accessible oral and pharyngeal cancers, including cancers of the lip, tongue, gum, floor of mouth, salivary gland and other oral cavities. This trial is currently being expanded to a multi-site trial with a focus on accelerated patient enrollment.

MVA-VLP-MUC1 for Solid Tumor Cancers – In March, GeoVax announced that the U.S. Patent and Trademark Office issued Patent No. 11278607, pursuant to the Company’s patent application No. 16/068,527 titled, “Compositions and Methods for Generating an Immune Response to a Tumor Associated Antigen.”The claims granted by the patent generally cover GeoVax’s vector platform for expressing tumor associated antigens in virus-like particles (VLPs) from a Modified Vaccinia Ankara (MVA) viral vector and encompass GeoVax’s Mucin 1 (MUC1) tumor-associated antigen immunotherapy candidate. The Company uses its GV-MVA-VLPTM vaccine platform to express abnormal, aberrantly glycosylated forms of the cell surface-associated MUC1 protein that is associated with a wide range of cancers, including breast, colon, ovarian, prostate, pancreatic, and lung.

During the first quarter, GeoVax began an IND-enabling animal study with Dr. Pinku Mukherjee at the University of North Carolina at Charlotte to define the optimal course and schedule of vaccination to define a protocol that can be evaluated in a Phase 1 clinical trial for the Company’s MVA-VLP-MUC1 immunotherapy candidate.

Pan-Coronavirus Vaccine (GEO-CM02) – In addition to the clinical programs for GEO-CM04S1 for COVID-19, GeoVax continued to assess GEO-CM02 as a potential single-dose universal coronavirus vaccine during the first quarter. This program was supported by a Small Business Innovation Research (SBIR) grant from the NIH during 2021. In small animal studies, the Company measured functional immune responses after a single dose that mediated protection from infection and pathogenesis, including protection against the more virulent Beta variant. Additional studies are planned for 2022 to prepare for IND filing and subsequent human clinical trials.

Operational Resources Strengthened – During the first quarter, GeoVax strengthened its organizational and operational resources in several areas to support our advancement through clinical development and regulatory registration.  These included:

• the appointment of Kelly T. McKee, Jr., M.D., M.P.H., to serve as the GeoVax’s Chief Medical Officer.
• the appointment of Jeffrey Welch to serve as Head, Process Development and Manufacturing Operations. 
• the creation and staffing of two new positions: Director, Clinical Operations (Erica Raiden) and Director, Project Management (Ashley Zuniga, Ph.D.), both key to effective management of our expanded operations.
• the engagement of CATO SMS to manage the ongoing Phase 1/2 trial of Gedeptin®therapy in patients with recurrent head and neck squamous cell carcinoma.
• the further engagement of CATO SMS to manage the two ongoingPhase 2 clinical trials of GEO-CM04S1, against SARS-CoV-2.

Additional Capital Resources – In January, GeoVax supplemented its cash resources through a private placementof common stock and warrants, with net proceeds of approximately $9.2 million, resulting in total cash balances at March 31, 2022 of $16.3 million.

Management Commentary

David Dodd, GeoVax’s Chairman and CEO, commented, “GeoVax’s corporate focus during the first quarter continued to be on the SARS-CoV-2 vaccine programs and our cancer immunotherapy programs. The three ongoing Phase 2 clinical trials in those areas represent the achievement of important goals established at the beginning of 2021. With the additional funding provided by the January private placement, we are well-positioned to advance these programs and we look forward to providing further updates on our progress throughout 2022.”

Financial Review

GeoVax reported a net loss for the three months ended March 31, 2022 of $2,427,515, as compared to $1,562,778 for the three months ended March 31, 2021.

Grant revenues were $81,526 for the three months ended March 31, 2022, as compared to $110,417 for the same period in 2021, reflective of the Company’s grant expenditures for its COVID-19 and Lassa Fever programs.

Research and development (R&D) expenses were $1,330,544 for the three months ended March 31, 2022 compared with $602,783 for the comparable period in 2021, with the increase primarily due to higher personnel and consulting costs, costs of manufacturing materials for use in clinical trials, and a generally higher level of activity.

General and administrative (G&A) expenses were $1,179,024 and $1,071,710 for the three months ended March 31, 2022 and 2021, respectively, with the increase primarily attributable to higher stock-based compensation expense.

GeoVax reported cash balances of $16.3 million at March 31, 2022, as compared to $11.4 million at December 31, 2021. Contributing to the increase in cash balances during the first quarter were net proceeds of $9.2 million from a private placement of common stock and warrants.
