Operations / Clinical Update

GeoVax President and Chief Executive Officer, Robert T. McNally, Ph.D. provided the following updates:

• Phase 2a Preventative Vaccine Trial Progressing

Our preventative HIV vaccine candidate is progressing in a Phase 2a clinical trial being conducted and funded by the HIV Vaccine Trials Network (HVTN).  Based on current patient enrollment rates, we expect the 300 participants in this trial to be fully enrolled by the end of 2010 and completed during 2011.  Our Phase 2a trial has been expanded from 225 to 300 participants to include an arm gathering additional data on three MVA injections, without the use of the DNA component, which is  an addition to the original arm testing two DNA priming and two MVA boosting injections.  Adding the simpler MVA-only arm to the trial was supported by scientific and clinical data.  The final decision on which inoculation format to take forward into the next set of clinical trials will be made once sufficient clinical data are available.

• Therapeutic Trial Screening Volunteers

With regard to our therapeutic vaccine candidate, the AIDS Research Consortium of Atlanta (ARCA) recently began patient recruitment for a Phase 1 clinical trial.  We intentionally designed this groundbreaking trial, which will be the first assessment of the vaccine performance in HIV infected humans, with stringent enrollment criteria for safety.  The trial is primarily designed as a safety study, but will also collect and report data on the vaccine's ability to elicit protective immune responses and control re-emergent virus during a pause in drug treatment.  Thus far, 23 individuals have been screened for possible participation in the trial. Out of these, 6 candidates remain for evaluation. As part of our protocol, a volunteer must have begun drug treatment in the first year of infection and have achieved 6 months of stable viral control on drug treatment before entry into the trial and receipt of the first vaccination.  We expect this trial to begin generating vaccine safety and performance data during the first half of 2011, with trial completion within 24 to 36 months.

• Phase 1 Preventative Trial Planning for our Adjuvanted Vaccine

Our pipeline product, which uses an adjuvant to boost the immune system response, demonstrated impressive results in preclinical trials.  In February this year, Dr. Harriet Robinson, our Chief Scientific Officer, presented these data at the Conference on Retroviruses and Opportunistic Infections (CROI).  The study investigated the use of co-expressed GM-CSF (granulocyte/macrophage colony-stimulating factor) as an adjuvant with the DNA priming component for the GeoVax DNA/MVA vaccine.  Results from this study showed total protection from infection (no evidence of infection) from simian immunodeficiency virus (SIV – monkey version of HIV) in 70% of animals who were given 12 weekly high-dose rectal exposures to the SIV virus.  We are very excited about the potential of this product as a second generation preventative HIV vaccine, and are targeting the start of Phase 1 human clinical testing in mid to late 2011.

About GeoVax Labs, Inc.

GeoVax is a biotechnology company developing human vaccines for diseases caused by HIV (Human Immunodeficiency Virus – that leads to AIDS) and other infectious agents. Our goals include developing HIV/AIDS vaccines for global markets, overseeing the manufacture and testing these vaccines under GMP/GLP conditions (FDA guidelines), conducting clinical trials for vaccine safety and effectiveness, and obtaining regulatory approvals to move the product forward. All preventative Phase 1 human clinical trials conducted to date tested various combinations and doses of our DNA and MVA vaccines, their ability to raise anti-HIV humoral (antibody) and cellular (cytotoxic T cell) immune responses, as well as, the vaccines' safety. Successful results from  Phase 1 testing supported the initiation of the first Phase 2 testing. GeoVax's Phase 2 human trial began in January 2009 and will ultimately involve 300 participants at sites in the United States and South America. Recently the FDA granted permission to proceed with a Phase 1 therapeutic trial for individuals infected with HIV. Long term, we expect that GeoVax will grant manufacturing and distribution rights in several global markets in return for upfront fees, collaborative development agreements, and royalties on sales and distribution revenues. Internal vaccine manufacturing and distribution will also be considered by GeoVax. For more information, please visit www.geovax.com.
