Condition(s) targeted: HIV Infections

Intervention: Atazanavir (immediate switch) (Drug); Atazanavir (Week 24 switch) (Drug)

Phase: Phase 3

Status: Completed

Sponsored by: Bristol-Myers Squibb

Official(s) and/or principal investigator(s):

The purpose of this clinical research study is to learn if atazanavir is associated with serum LDL cholesterol in HIV-infected subjects following a substitution of atazanavir for their previously administered protease inhibitor.

Clinical Details

Study design: Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Time to virologic rebound for subjects with HIV RNA < 50 c/mL at baseline; Magnitude/ durability of increases from baseline in absolute CD4 (Time-Averaged Difference) through WK12; Mean % change from baseline in fasting LDL cholesterol at WK12.


Minimum age: 16 Years. Maximum age: N/A. Gender(s): Both.
