ATLANTA, GA - (NewMediaWire) - November 08, 2023 - GeoVax Labs, Inc. (Nasdaq: GOVX), a biotechnology company developing immunotherapies and vaccines against cancers and infectious diseases, today announced financial results for the third quarter ended September 30, 2023 and provided a business update.


“We are thrilled to see material advancements across all aspects of our business. Through the third quarter, we are delivering on our promise to bring transformative change to the treatment of COVID-19 by completing enrollment in our healthy volunteer Phase 2 clinical trial evaluating GEO-CM04S1 as a potentially more robust, more durable booster vaccine. In addition, with two additional Phase 2 trials ongoing in immunocompromised population, and recent publication of positive safety and potent immunogenicity data in this population, we have strengthened our conviction in the potential of our next-generation COVID-19 vaccine (GEO-CM04S1) for immunocompromised patients. We believe the need for new treatment options for immunocompromised patients in the fight against COVID-19 is significant, particularly as we begin to enter the winter surges of this diseases, where these patients will be left most vulnerable,” said David Dodd, Chief Executive Officer of GeoVax.


“We are preparing to announce initial data readouts from two of our Phase 2 GEO-CM04S1 trials as well as updates from our Gedeptin® clinical trial against head and neck cancer in the coming months. Earlier this summer, we were delighted to present clinical data which revealed the safe and feasible administration of Gedeptin®. We believe the Gedeptin mechanism of action to be solid tumor agnostic, and therefore offers the potential as a therapeutic option for multiple cancer types and positions the product for long-term growth. The third quarter of 2023 also saw new patents issued for our Ebola, Marburg, Malaria, and HIV vaccines, demonstrating the strength of our team’s ability to execute on our broader strategy. In addition, we advanced our manufacturing process through the signing of a landmark multi-product commercial license agreement with ProBioGen for the use of their AGE1.CR.PIX®suspension cell line. We believe that these catalysts altogether will have a profound impact on patients in need and all our stakeholders.”


Recent Business Achievements



  • Enrollment completed for Phase 2 clinical trial evaluating GEO-CM04S1 as a booster for healthy patients who have previously received the Pfizer or Moderna mRNA vaccine in September of 2023. An initial data readout is expected soon.


  • GEO-CM04S1 demonstrated potent antibody and cellular immunity in immunocompromised patients in a recent publication in the journal, Vaccines, in August 2023. GeoVax’s Phase 2 clinical trial evaluated the safety and immunogenicity of GEO-CM04S1, compared to either the Pfizer/BioNTech or Moderna mRNA-based vaccine in patients who have previously received an allogeneic hematopoietic cell transplant, an autologous hematopoietic cell transplant or CAR-T cell therapy. Most promising in the results published was the demonstration of the potential of GEO-CM04S1 as a variant agnostic COVID-19 vaccine, providing potent immunity from the Wuhan through Delta and Omicron strains.

-      In October 2023, GeoVax commenced the planned site expansion for this trial to accelerate patient enrollment. In addition to study enrollments completed at the City of Hope Medical Center (Duarte, California), the trial is now open at Wake Forest Baptist Medical Center (Winston Salem, North Carolina), the University of Massachusetts Medical Center (Worcester, Massachusetts), and Fred Hutchinson Cancer Center (Seattle, Washington).


  • Commenced investigator-initiated randomized observer-blinded Phase 2 clinical trial of COVID-19 boosters with GEO-CM04S1 or Pfizer-BioNTech bivalent vaccines in patients with chronic lymphocytic leukemia (CLL) in July of 2023. The trial is rapidly enrolling patients and progressing towards an interim data review.


  • Presented data for GEO-CM02 at the Keystone Symposia Conference in an abstract titled, MVA-vector multi-antigen COVID-19 vaccines induce protective immunity against SARS-CoV-2 variants spanning Alpha to Omicron in preclinical animal models in September of 2023. The data revealed that the GEO-CM02 vaccine induced immune responses that were efficacious against the original Wuhan strain and Omicron variants with a single dose. This effort expands upon GeoVax’s hypothesis that vaccines designed to induce both antibodies and T-cell responses to multiple viral structural proteins can address the issue of viral variation and escape from the immune system without the need for repeated seasonal adjustments.



  • Gedeptin® clinical data presented at the AACR-AHNS Head and Neck Cancer Conference in an abstract titled, Phase 1/2 study of Ad/PNB with Fludarabine for the Treatment of Head and Neck Squamous Cell Carcinoma (HNSCC) in July 2023. The FDA-funded study revealed that the administration of Gedeptin® is safe and feasible.


Advanced Vaccine Manufacturing Process

  • GeoVax and ProBioGen announced the signing of a landmark multi-product commercial license agreement for ProBioGen’s groundbreaking AGE1.CR.PIX® suspension cell line in September 2023. The agreement enhances the manufacturing capabilities of GeoVax’s entire Modified Vaccinia Ankara (MVA)-based vaccine portfolio with respect to both scale and flexibility. This follows the May 2023 agreement with Advanced Bioscience Laboratories, Inc. (ABL) to support current Good Manufacturing Practices (cGMP) production of the Company’s vaccine candidates. These agreements move the Company toward fully implementing a continuous cell line manufacturing system that will provide lower-cost, scalable versatility for our entire MVA-based vaccine portfolio.

About GeoVax


GeoVax Labs, Inc. is a clinical-stage biotechnology company developing novel therapies and vaccines for solid tumor cancers and many of the world’s most threatening infectious diseases. The company’s lead program in oncology is a novel oncolytic solid tumor gene-directed therapy, Gedeptin®, presently in a multicenter Phase 1/2 clinical trial for advanced head and neck cancers. GeoVax’s lead infectious disease candidate is GEO-CM04S1, a next-generation COVID-19 vaccine targeting high-risk immunocompromised patient populations. Currently in three Phase 2 clinical trials, GEO-CM04S1 is being evaluated as 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, and as a booster vaccine in patients with chronic lymphocytic leukemia (CLL). In addition, GEO-CM04S1 is in a Phase 2 clinical trial evaluating the vaccine as a more robust, durable COVID-19 booster among healthy patients who previously received the mRNA vaccines. GeoVax has a leadership team who have driven significant value creation across multiple life science companies over the past several decades. For more information, visit our website:
