Study Of Chemokine Coreceptor 5 (CCR5) Antagonist GW873140 In R5/X4-Tropic Treatment-Experienced HIV-Infected Subjects
A Phase III, Randomized, Double-blind, Placebo-controlled, Multicenter, Parallel Group Study to Compare the Efficacy and Safety of GW873140 400mg BID in Combination With a Ritonavir-containing Optimized Background Therapy (OBT) Regimen Versus Placebo Plus OBT Over 48 Weeks.

The purpose of this study is to evaluate the safety and efficacy of the CCR5 antagonist GW873140 or placebo in combination with an optimized background regimen in treatment-experienced HIV-infected subjects with R5/X4-tropic virus

  • R5/X4-tropic virus at screening.
  • Total prior antiretroviral experience of at least 3 months.
  • Documented resistance to at least one drug in each of the following classes: nucleoside reverse transcriptase inhibitors (NRTI), non-nucleoside reverse transcriptase inhibitors (NNRTI), and protease inhibitors (PI), stable antiretroviral regimen (or no antiretroviral treatment) for at least 4 weeks before screening.
