About

The purpose of this study is to see if it is safe and effective to add DMP 266 to an anti-HIV treatment program of indinavir and nucleoside reverse transcriptase inhibitors (NRTIs).

Full description

In this double-blind, placebo-controlled study, 300 patients are randomized to 1 or 2 reverse transcriptase inhibitors of their choice plus blinded therapy on Arm A or B as follows:

Arm A: DMP 266 placebo plus indinavir. Arm B: DMP 266 plus indinavir. After 16 weeks, patients may switch the NRTI portion of their regimen if they meet a treatment failure criterion. After the completion of the 24-week period, patients have the option to continue on open-label DMP 266 and indinavir.
