BATAR: Individuals Currently Taking Boosted Atazanavir as Part of an HIV Treatment Regimen Will be Evaluated to See if Substituting Raltegravir for Nucleoside Transcriptase Inhibitors Will be Safe and Well Tolerated. (BATAR)

A Pilot Study of the Novel Antiretroviral Combination of Atazanavir and Raltegravir in HIV-1 Infected Subjects With Virologic Suppression on a Standard Regimen of Boosted Atazanavir, Tenofovir and Emtricitabine

The purpose of this Phase IV pilot study is to evaluate the safety, tolerability, and satisfaction of a nucleoside analog reverse-transcriptase inhibitors (NRTI)sparing regimen for participants fully suppressed on an atazanavir/ritonavir based highly active antiretroviral therapy (HAART)regimen plus emtricitabine/tenofovir (Truvada). Several pharmacologic factors support this concept including the favorable drug interaction between atazanavir and raltegravir. Participants will be randomized to either continue on their current regimen or one of two study arms (atazanavir 300mg plus ritonavir 100mg daily plus raltegravir 400mg twice daily or atazanavir 300mg twice daily plus raltegravir 400mg twice daily). Participants will be followed for 48 weeks for safety, tolerability, and satisfaction. After baseline, the participants will have six clinic visits for evaluation and labs.

The Change in Adherence to Study Treatment Arm From Baseline to Week 48
Tidsramme: Baseline and Week 48
Adherence to study treatment reported as the percentage of doses of the prescribed treatment arm regimen taken, described by each subject through recall of dosing in the three days prior to the visit Baseline and Week 48 vistis. The change in adherence is reflected as the difference of the mean percentage of adherence per arm between Baseline and Week 48 visits.
Baseline and Week 48
Change in Quality of Life From Baseline to 48 Weeks of Study Treatment
Tidsramme: baseline and 48 weeks
Quality of Life was measured by self report using a standardized scale, where 0 is death and 100 is perfect health. The baseline measure was obtained prior to initiation of study treatment arm. The week 48 measure captures Quality of Life by self report at 48 weeks of study treatment.
