On Tuesday, Vertex Pharmaceuticals Inc. and Burroughs Wellcome
Co. announced the commencement of a Phase I clinical trial for
VX-478 in the United States. The trial is a dose escalation
trial designed to test the tolerability, pharmacokinetics, and
oral bioavailability of VX-478, an orally administered
protease inhibitor for the treatment of HIV infection and AIDS
that was designed by Vertex. The study is the first in an
international clinical development program for VX-478 being
undertaken by Burroughs Wellcome, Kissei Pharmaceutical Co.,
and Vertex. Burroughs Wellcome and Kissei will use the results
of the trial to develop trials to determine the safety and
anti-HIV efficacy of VX-478 alone and in combination with
reverse transcriptase inhibitors. "The Burroughs Wellcome-
sponsored clinical program and the Kissei studies planned for
Japan are part of an effort that is both extensive and
designed to generate data rapidly on VX-478," said Dr. Joshua
Boger, President and CEO of Vertex. "We and our partners
believe that the pharmaceutical attributes of VX-478 make it a
very promising drug candidate for the treatment of AIDS and
HIV infection."
