GEO-CM04S1 Demonstrates Superior Protection in Immunocompromised Populations; Fully Aligned with HHS Priorities for Durable, Broad-Spectrum Immunization

ATLANTA, GA, May 20, 2025 – GeoVax Labs, Inc. (Nasdaq: GOVX), a clinical-stage biotechnology company developing vaccines and immunotherapies for infectious diseases and cancer, today issued a statement in response to the U.S. Department of Health and Human Services’ (HHS) anticipated changes to COVID-19 vaccine recommendations.

According to recent reports, HHS is preparing to limit blanket vaccine guidance in favor of a risk-based approach focused on older adults and those with chronic health problems. This pivot away from one-size-fits-all vaccine recommendations underscores the urgent need for next-generation immunization strategies—precisely the role that GeoVax’s multi-antigen COVID-19 vaccine, GEO-CM04S1, is designed to fulfill.

“As public health strategy shifts toward protecting those most vulnerable, the demand increases for vaccines that work where others fall short,” said David Dodd, Chairman and CEO of GeoVax. “GEO-CM04S1 delivers broad, durable immunity even in immunocompromised patients—a population estimated at over 40 million adults in the U.S. that are inadequately served by the current authorized, single-antigen mRNA vaccines.”

GEO-CM04S1: Purpose-Built for the New Vaccine Paradigm

GEO-CM04S1 is based on the Modified Vaccinia Ankara (MVA) platform and expresses both Spike (S) and Nucleocapsid (N) proteins—offering multi-antigen protection against SARS-CoV-2. This broader design induces both antibody and T cell responses, essential for robust, durable protection against continually evolving COVID-19 variants and is especially critical in populations with weakened immune systems.

Recent interim results from a Phase 2 clinical trial in patients with chronic lymphocytic leukemia (CLL) demonstrated a superior T cell response rate versus a leading mRNA vaccine. The trial’s independent Data Safety Monitoring Board recommended and implemented continuing enrollment in the GEO-CM04S1 arm while halting the underperforming mRNA comparator arm.

Aligned with the New HHS Biosecurity Vision

GEO-CM04S1 is fully aligned with the new strategic direction from HHS Secretary Kennedy, who has called for a focus toward multi-antigen vaccine technologies that can deliver durable, variant-adaptive immunity while prioritizing safety and domestic production.

GeoVax’s MVA vaccines offer:

• Multi-antigen breadth: Including both S and N antigens for protection across variants.
• Durability: Sustained antibody and T cell immunity—even in immunocompromised individuals.
• Safety: MVA is non-replicating and approved for use in vulnerable groups such as transplant patients, pregnant women, and children.
• Domestic advanced manufacturing: Using an avian continuous cell line platform that eliminates reliance on specialized pathogen-free eggs and a slow vaccine manufacturing process, enabling scalable U.S.-based vaccine production aligned with President Trump’s recent Executive Order on pharmaceutical onshoring.

“The HHS call for broader, more resilient vaccine solutions is well-founded,” Dodd added. “GEO-CM04S1 is not only scientifically advanced but strategically aligned with our nation’s public health and biosecurity goals.”

Multiple Trials Support Path to Licensure

GEO-CM04S1 is currently in three active Phase 2 trials, evaluating its use among:

1. Immunocompromised blood cancer patients in preparation for stem cell transplantation or CAR-T therapy (in comparison to mRNA-based vaccine),  
2. Immunocompromised patients with Chronic Lymphocytic Leukemia (in comparison to mRNA vaccine), and
3. Healthy adults, previously vaccinated with a mRNA vaccine as a more robust, more durable booster following mRNA vaccination.

Allowed Patent Claims Cover the Synergistic Combination of Gedeptin® Therapy with Radiation As a Targeted Approach for Solid Tumors

Atlanta, GA – May 7, 2025 – GeoVax Labs, Inc. (Nasdaq: GOVX), a clinical-stage biotechnology company developing immunotherapies and vaccines against solid tumors and infectious diseases, announced today that the U.S. Patent and Trademark Office has issued a Notice of Allowance related to U.S. patent application 17/502,101 entitled “Enhanced Therapeutic Usage of a Purine Nucleoside Phosphorylase or Nucleoside Hydrolase Prodrug”. The allowed claims further strengthen GeoVax’s intellectual property position in the oncology space.

The allowed claims describe a method for treating solid tumors—including glioblastoma, breast, prostate, head and neck, glioma, and lung cancers—through the direct intratumoral administration of an adenoviral vector encoding purine nucleoside phosphorylase (Ad/PNP), followed by local administration of the prodrug fludarabine phosphate (F-araAMP), and subsequent radiation therapy. This triple-combination strategy is designed to generate local, targeted cytotoxic activity within the tumor microenvironment while minimizing systemic toxicity.

The allowed patent joins the growing Gedeptin intellectual property portfolio, which was exclusively licensed to GeoVax through a prior agreement with PNP Therapeutics, Inc. and the University of Alabama at Birmingham (UAB)/Southern Research. Under the agreement, GeoVax has assumed all licensing rights and IP prosecution responsibilities for the Gedeptin platform.

David Dodd, Chairman and CEO of GeoVax, commented, “This allowed patent underscores the clinical and commercial promise of our Gedeptin platform and demonstrates our commitment to expanding therapeutic options for patients with difficult-to-treat cancers. While the claims do not directly mirror our ongoing clinical programs, they establish a critical foundation for future directions, including potential integration with advanced delivery systems for tumors that are challenging to access.”

Dodd continued, “The USPTO’s recognition of this therapeutic method further validates our approach and underscores the growing value of our wholly owned, co-owned, and in-licensed intellectual property estate, now standing at over 135 granted or pending patent applications spread across 23 distinct patent families”.

Having successfully completed a Phase 1/2a study, as monotherapy in advanced head and Neck cancer patients, Gedeptin is scheduled to begin a Phase 2 trial in combination with an Immune Check Inhibitor (ICI) for patients with first recurrence of head and neck cancer. The newly allowed claims provide further protection as GeoVax explores expanded applications, including novel device-based delivery approaches in potential partnership with interventional oncology companies.

About Gedeptin

Gedeptin is a viral-vectored gene therapy that employs a non-replicating adenoviral vector encoding the E. coli enzyme purine nucleoside phosphorylase (PNP). When injected directly into a tumor and followed by systemic administration of the prodrug fludarabine phosphate, PNP enzymatically converts the prodrug into a cytotoxic metabolite (fluoroadenine), resulting in selective killing of tumor cells by disrupting RNA and protein synthesis.

This tumor-targeted approach offers several key advantages:

• Localized cytotoxicity with reduced systemic side effects,
• Potential synergy with immune checkpoint inhibitors (ICIs),
• Applicability across multiple solid tumor types, particularly those accessible for intratumoral injection.

Gedeptin will soon be evaluated in a Phase 2 clinical trial for patients with first recurrence of head and neck cancer in combination with an approved ICI. It has been granted Orphan Drug Designation by the U.S. FDA for intratumoral treatment of oral and pharyngeal cancers.

GEO-CM04S1 Demonstrates Durable T Cell and Antibody Responses in Healthy and Immunocompromised Populations

ATLANTA, GA, April 24, 2025 – GeoVax Labs, Inc. (Nasdaq: GOVX), a clinical-stage biotechnology company developing vaccines and immunotherapies for infectious diseases and cancer, today recapped the successful presentation of new clinical data on its multi-antigen SARS-CoV-2 vaccine candidate, GEO-CM04S1, delivered at the 25th Annual World Vaccine Congress in Washington, D.C.

The presentation, titled “Phase 2b Study Results That Evaluated and Compared GeoVax’s Multi-Antigen Vaccine Candidate (GEO-CM04S1) to an Approved Vaccine Against COVID-19,” was given by Don J. Diamond, Ph.D. on April 24, 2025. It highlighted results across several Phase 1 and 2 clinical trials, including studies involving healthy volunteers as well as immunocompromised patients such as stem cell transplant recipients and those with chronic lymphocytic leukemia (CLL).

GEO-CM04S1, based on the synthetic Modified Vaccinia Ankara (MVA) vector platform, uniquely expresses both the Spike (S) and Nucleocapsid (N) antigens of SARS-CoV-2—resulting in broad and durable immune responses even in populations that have historically responded poorly to mRNA vaccines.

Key Highlights from the Clinical Data Presented

Robust Immune Response in Healthy Adults

• In a Phase 1 trial, 100% of participants (34/34) seroconverted (i.e., produced antibodies) for Spike IgG, and 94% (32/34) for Nucleocapsid IgG.
• 98% (48/49) demonstrated a T cell response to either antigen following vaccination.
• No serious safety concerns were reported across varying dose levels.

Comparable Immunogenicity at Lower Doses (Phase 2 Booster Trial)

• Healthy volunteers who had previously received mRNA or protein-based COVID-19 vaccines were boosted with GEO-CM04S1 at two dose levels (10⁷ vs 10⁸ pfu).
• Spike, RBD, and Nucleocapsid IgG antibody responses, as well as neutralization titers against multiple COVID-19 variants (including XBB.1.5), increased significantly at both dose levels with no meaningful differences between them.
• T cell responses increased significantly post-vaccination, regardless of baseline immunity.

Superior Performance in Immunocompromised Populations

• In stem cell transplant recipients, GEO-CM04S1 induced ELISA antibody titers and T cell responses that exceeded those observed in healthy volunteers.
• In a randomized Phase 2 trial comparing GEO-CM04S1 to the Pfizer-BioNTech (Comirnaty®) vaccine in patients with Chronic Lymphocytic Leukemia, GEO-CM04S1 demonstrated a significantly higher T cell response rate.
  • At Day 56 of the study: 6 of 15 patients in the GEO-CM04S1 arm achieved ≥3-fold increases in Spike or Nucleocapsid-specific T cells versus 2 of 14 in the Comirnaty arm.
  • The Data and Safety Monitoring Board (DSMB) recommended halting enrollment in the Pfizer arm due to underperformance, while continuing enrollment of the GEO-CM04S1 arm.

“We were pleased to share these promising results with global leaders in vaccinology,” said Don J. Diamond, Ph.D. “The data underscore the value of our dual-antigen approach, particularly for patients underserved by existing single-antigen vaccines. GEO-CM04S1 not only drives strong antibody and T cell immunity in healthy adults, but also in the immunocompromised—a population historically underserved by single-antigen mRNA vaccines.”

David A. Dodd, Chairman, President, and CEO of GeoVax, added: “The clinical performance of GEO-CM04S1 across diverse and high-risk populations supports our mission to deliver broad and lasting protection through next-generation vaccines. Our data continues to demonstrate strong, durable immune responses in both healthy and immunocompromised populations—a critical feature of our vaccine for public health preparedness. As we continue to advance this program, these results reinforce our confidence in the MVA platform as a foundation for addressing future public health threats.”

About GEO-CM04S1

GEO-CM04S1 is a next-generation COVID-19 vaccine based on the Modified Vaccinia Ankara (MVA) vector originally developed at City of Hope. Its multi-antigen design expresses both Spike and Nucleocapsid proteins of SARS-CoV-2, promoting broad, cross-reactive immunity. The vaccine is being evaluated in three ongoing Phase 2 clinical trials.

Company Reaffirms Commitment to Innovation in COVID-19, Oncology, and Biosecurity Amid Strategic Program Developments

ATLANTA, GA, April 16, 2025 – GeoVax Labs, Inc. (Nasdaq: GOVX), a clinical-stage biotechnology company developing vaccines and immunotherapies for infectious diseases and cancer, today addressed the termination of its Project NextGen (PNG) award by the Biomedical Advanced Research and Development Authority (BARDA), effective April 11, 2025. The Company also provided a comprehensive business update across its core programs, including the next-generation COVID-19 vaccine (GEO-CM04S1), cancer immunotherapy (Gedeptin^®), Mpox/smallpox vaccine (GEO-MVA), and advanced MVA manufacturing process.

GeoVax expressed disappointment in the HHS/BARDA action but remains committed to the critical medical need addressed by GEO-CM04S1, particularly among the more than 40 million immunocompromised Americans—and over 400 million people globally—who remain inadequately protected by the current authorized COVID-19 vaccines.  Thus far, clinical data in support of GEO-CM04S1 demonstrate encouraging support of the potential of GEO-CM04S1 for providing (a) more robust immune response, (b) increased durability and (c) protective immunity for those patients with depleted immune systems inadequately responding to the current authorized COVID-19 vaccines.

The Company also noted recent public statements by HHS leadership acknowledging the potential enhanced value of multi-antigen vaccines addressing respiratory viruses.  Of special note is that GEO-CM04S1 was the only multi-antigen/polyvalent COVID-19 vaccine candidate selected under the PNG initiative.

“While the recent HHS/BARDA Stop Work Order action was disappointing and surprising, our commitment to protecting vulnerable populations remains unchanged, and our clinical momentum is strong in support of our ongoing Phase 2 GEO-CM04S1 programs,” said David Dodd, Chairman and CEO of GeoVax.

Continued Progress Across a Catalyst-Rich Pipeline

GEO-CM04S1: Advancing to Meet Unmet COVID-19 Needs

GEO-CM04S1 continues to demonstrate potential as both a primary and booster vaccine, especially in immunocompromised patients. Key milestones anticipated during 2025 include:

• Healthy Adult Booster Trial – Enrollment is complete; data readout expected in H1 2025.
• CLL Patient Study (Immunocompromised patient study) – Ongoing enrollment; interim results resulted in continuation of the GEO-CM04S1 arm, whereas the Data Safety Review Board recommended early termination of the mRNA arm, which was subsequently implemented.
• Stem Cell Transplant/CAR-T Trial (Immunocompromised patient study) – Enrollment and evaluation continue among hematological patients receiving stem cell transplantation or CAR-T therapy, comparing GEO-CM04S1 to mRNA COVID-19 vaccines.

GEO-CM04S1 is a multi-antigen COVID-19 vaccine, utilizing a synthetic-MVA platform, expressing both S and N antigens, offering the potential for broader, more durable protection than current mRNA vaccines.

Gedeptin^®: Advancing into Phase 2 in Solid Tumors

GeoVax’s oncology program, utilizing the Gedeptin^® technology, is planned to progress to a Phase 2 trial in combination with an immune checkpoint inhibitor for first recurrent head and neck cancer. Gedeptin has received Orphan Drug designation for use among advanced head & neck cancer patients.  The Gedeptin technology provides potential for expansion into other solid tumors including triple-negative breast cancer, melanoma, and soft tissue sarcoma.

GEO-MVA: Addressing Biosecurity and Global Vaccine Equity

GeoVax anticipates initiating clinical trials in 2025 for GEO-MVA, its Mpox/smallpox vaccine candidate. The Company has successfully produced cGMP clinical product and is focused on completing the vaccine vialing in support of initiating clinical evaluation during H2 2025.  GEO-MVA positions GeoVax to offer a U.S.-developed alternative to foreign-sourced vaccines amid rising global biosecurity threats and constrained supply.

Advanced Manufacturing: Scaling MVA for Global Reach

GeoVax is advancing continuous cell line manufacturing for MVA-based vaccines, offering a path to scalable, cost-effective production—including localized manufacturing for low- and middle-income countries. This innovation addresses critical gaps in vaccine self-sufficiency and supply resilience.

Outlook for 2025

Despite the PNG award termination, GeoVax anticipates a milestone-rich 2025 across its portfolio. The Company will continue to engage with government and industry partners, pursue clinical trial completions, and drive innovation through expanded AI integration to optimize development, trial operations, and manufacturing efficiency.

“Our scientific foundation is strong and our strategy is clear,” added Dodd. “GeoVax remains committed to delivering transformative solutions for unmet medical needs in infectious disease and cancer. We’re advancing with purpose and fully prepared to deliver on the promise of our development program.”

About GeoVax

GeoVax Labs, Inc. is a clinical-stage biotechnology company developing novel vaccines for many of the world’s most threatening infectious diseases and therapies for solid tumor cancers. The company’s lead clinical program is GEO-CM04S1, a next-generation COVID-19 vaccine for which GeoVax was recently awarded a BARDA-funded contract to sponsor a 10,000-participant Phase 2b clinical trial to evaluate the efficacy of GEO-CM04S1 versus an approved COVID-19 vaccine. In addition, GEO-CM04S1 is currently in three Phase 2 clinical trials, being evaluated as (1) a primary vaccine for immunocompromised patients such as those suffering from hematologic cancers and other patient populations for whom the current authorized COVID-19 vaccines are insufficient, (2) a booster vaccine in patients with chronic lymphocytic leukemia (CLL) and (3) a more robust, durable COVID-19 booster among healthy patients who previously received the mRNA vaccines. In oncology the lead clinical program is evaluating a novel oncolytic solid tumor gene-directed therapy, Gedeptin®, having recently completed a multicenter Phase 1/2 clinical trial for advanced head and neck cancers. A Phase 2 clinical trial in first recurrent head and neck cancer, evaluating Gedeptin^® combined with an immune checkpoint inhibitor is planned. GeoVax has a strong IP portfolio in support of its technologies and product candidates, holding worldwide rights for its technologies and products. The Company has a leadership team who have driven significant value creation across multiple life science companies over the past several decades.
