Four-Drug Combination Treatment in Hiv-Infected Subjects Failing Therapy With Antiretroviral Regimens
A Phase 2, Randomized, Double-Blind, Dose-Ranging Study Of Capravirine (AG1549) In Combination With Kaletra (Trademark) and At Least 2 Nucleoside Reverse Transcriptase Inhibitors in Hiv-Infected Subjects Who Have Failed Antiretroviral Regimens Containing Protease Inhibitors, Nonnucleoside Reverse Transcriptase Inhibitors, and Nucleoside Reverse Transcriptase Inhibitors
This is a 48 week study for HIV-infected patients who have failed several regimens including PI's, NNRTs and NRTIs. Patients will be randomly selected to be in 1 of 4 groups. Three of the 4 groups will contain capravirine in different doses combined with Kaletra and nucleosides and one of the groups will be a combination of Kaletra and nucleosides without the capravirine.
