U.S. Government Awards $15 Million Grant to GeoVax Labs Inc. Labs’ HIV/AIDS Vaccine Program

ATLANTA, Sept. 26 /PRNewswire-FirstCall/ -- GeoVax Labs, Inc. , an Atlanta based biotechnology company, announced receipt of an estimated $15,000,000 Integrated Preclinical/Clinical AIDS Vaccine Development [IPCAVD] Grant to support its HIV/AIDS vaccine program.

This large Grant was awarded by the National Institutes of Health-National Institute of Allergy & Infectious Disease [NIH-NIAID], an agency of the U.S. Government. Funding commences October 2007.

Only meritorious HIV/AIDS prevention vaccine candidates are considered to receive an IPCAVD award. Candidate companies are highly scrutinized and must supply substantial positive AIDS vaccine data to support their application. IPCAVD grants are awarded on a competitive basis and are designed to support later stage vaccine research, development and human trials.

GeoVax will utilize this funding to further its HIV/AIDS vaccine development, optimization, production and human clinical trial testing including Phase 2 human clinical trials planned for 2008.

Dr. Harriet Robinson, Chief Scientific Advisor for GeoVax, guided development of the IPCAVD proposal and will lead a major part of its related studies. Dr. Robinson stated, “This grant will allow GeoVax to move forward our AIDS vaccine evaluation program more efficiently and more rapidly.”

“Our selection as a grant recipient is a validation of our vaccine technology, scientific program, success in human trials to date and future strategies,” said GeoVax President/CEO, Don Hildebrand. “This $15 million in funding will support additional AIDS vaccine studies as well as expansion of our scientific team at GeoVax.”

GeoVax HIV/AIDS vaccines are designed to prevent development of Acquired Immunodeficiency Disease (AIDS), caused by the virus known as HIV-1, by vaccinating individuals prior to infection with the AIDS virus.

Studies evaluating these vaccines in already HIV/AIDS infected individuals are being planned.

GeoVax DNA and Recombinant MVA HIV/AIDS vaccines: -- Use DNA vaccines to “prime” immune responses and MVA vaccines to “boost” immune responses against the AIDS virus -- Vaccinate against more than 50% of AIDS virus components and can not cause AIDS -- Protected 22 of 23 (96%) non-human primates for over 3 1/2 years post-infection with an AIDS inducing virus. Five of six non-vaccinated controls died of AIDS within the 1st year of infection. These trials used a prototype SIV/HIV vaccine for the HIV vaccine that is being advanced in human trials -- Are manufactured & tested under GMP/GLP - EMEA (EU) and FDA guidelines -- Satisfactorily completed earlier DNA HIV/AIDS vaccine Phase 1 human trial -- Are currently being tested in 4 Human Trials. Two started in 2006, two in summer 2007 -- Have been demonstrated safe to date in human trials -- Are demonstrating positive immune responses against HIV in majority of vaccine recipients -- Are in planning stage for a larger Phase 2 human trial in 2008
