Inhibitex HIV Integrase Inhibitor Data Presented at 15th Annual Conference on Retroviruses and Opportunistic Infections.

ATLANTA -- Inhibitex, Inc. (Nasdaq: INHX), a biopharmaceutical company focused on the development of novel antiviral agents, announced today that preclinical data relating to INH-001, one of several potential lead candidates from Inhibitex's HIV integrase inhibitor program, were presented during this week's 15th Annual Conference on Retroviruses and Opportunistic Infections (CROI), held February 3-6, 2008, in Boston, MA. Dr. Vasu Nair, Director of the University of Georgia Center for Drug Discovery and head of the Department of Pharmaceutical and Biomedical Sciences, presented data from several preclinical studies of INH-001, which in addition to its pharmacokinetic properties, demonstrated metabolic stability in vitro, multiple mechanisms of action and no significant inhibition of CYP450 proteins.

"We are very encouraged by the preliminary data from these early studies involving INH-001, as well as studies involving compounds from a second series within our integrase inhibitor program," stated Dr. Joseph M. Patti, Chief Scientific Officer. "We continue to evaluate compounds from these series and anticipate completing our lead optimization efforts and selecting a lead clinical candidate from this program later this year."

About Inhibitex's HIV Integrase Inhibitors

Integrase inhibitors are an emerging class of antiretroviral agents that block the insertion of viral DNA into the host cell genome, thereby preventing further replication and the establishment of a latent proviral reservoir. By inhibiting a different molecular target than other classes of approved antiretroviral drugs, integrase inhibitors have the potential to treat patients with highly resistant strains of HIV. Further, integrase-resistant strains have already emerged during treatment with the only currently approved integrase inhibitor, as well as others in advanced clinical development. Inhibitex's series of potent integrase inhibitors have previously been shown to inhibit both the strand transfer (ST) and 3'processing steps of HIV integrase and have the potential to possess antiviral activity against other known integrase-resistant strains of HIV.
