GeoVax Labs Inc.: Excellent Safety and Reproducible Immunogenocity Demonstrated in Early Results of Phase 2a Trial for HIV Preventative Vaccine
Of particular interest are assay results measuring vaccine-induced cellular (T-cell) immune responses, which are available for 128 of the participants. These tests revealed cellular immune response rates similar to those observed in the Phase 1 trial. Additional testing is ongoing to measure antibody responses and to further characterize cellular immune responses. Data will continue to be accumulated as the trial is completed.
"The high level of safety was expected" said Dr. Harriet Robinson, Chief Scientific Officer of GeoVax, "because of the excellent tolerability of recombinant DNA and recombinant MVA vaccine vectors in humans in our, as well as other prior trials. The apparent reproducibility of vaccine immunogenicity is very encouraging. The immunogenicity data not only indicate that our vaccine products are functioning as designed but also demonstrate the capabilities of the central HVTN laboratory whose scientists have developed and validated the assays that are so critical to clinical vaccine testing."
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 GeoVax began enrolling patients in a Phase 1 therapeutic trial for individuals already infected with HIV. For more information, please visit www.geovax.com.
