About Bevirimat

Bevirimat has demonstrated potent activity against a broad range of HIV strains, and laboratory studies have shown bevirimat to be an inhibitor of HIV isolates that are resistant to currently approved HIV drugs. Nearly 650 subjects, including over 100 HIV-infected patients, have been studied in clinical trials. Results from these trials have shown bevirimat to be well tolerated and have demonstrated significant and clinically relevant reductions in viral load in a subset of HIV-infected patients. Epidemiology data show that this subset represents a majority of HIV infected patients. Bevirimat is currently in Phase 2b clinical studies using a new tablet formulation that has an oral bioavailability and pharmacokinetic profile comparable to the previous solution formulation.

Myriad Pharmaceuticals, Inc.

Myriad Pharmaceuticals, Inc. is currently a wholly owned subsidiary of Myriad Genetics, Inc. (NASDAQ: MYGN). Myriad Pharmaceuticals anticipates becoming an independent, publically-traded company by the end of the second calendar quarter of 2009.
