HIV Protease Inhibitor Granted Fast Track Review Status
"The Food and Drug Administration's fast track designation for 640385 highlights the productive collaboration between Vertex and GlaxoSmithKline, which has generated three novel HIV protease inhibitor product candidates over the past 12 years, and has established both companies as leaders in the development of new drugs to treat HIV infection," said Joshua Boger, Ph.D., Chairman, President and CEO of Vertex. "This designation recognizes the clinical and nonclinical results for 640385, which support the potential to address the needs of patients with resistant HIV strains."
Under the FDA Modernization Act of 1997, fast track designation indicates that the FDA will facilitate the development and may expedite the review of a drug if it is intended for the treatment of a serious or life-threatening condition, and demonstrates the potential to address an unmet medical need for such a condition. Support of this fast track designation was based on positive Phase IIa data from a clinical study of 640385 in HIV-infected patients, as well as results from in vitro studies indicating 640385's antiviral activity against HIV-1 strains resistant to a number of currently marketed protease inhibitors. Vertex expects that GSK will present preliminary Phase IIa results at a medical conference in the second half of 2005.
