Study Endpoints

Primary Endpoints

Change From Baseline in Human Immunodeficiency Virus (HIV-1) Viral Load (Ribonucleic Acid [RNA])
Baseline to Week 24 and Week 48

Change from baseline in log 10-transformed plasma viral load (HIV-1 RNA) levels (log 10 copies per milliliter \[log10 copies/mL\]). Baseline value calculated as average of pre-dose measurements collected at screening, randomization, and baseline visits.

Secondary Endpoints

Number of Subjects With HIV-1 RNA Levels < 400 Copies/mL
Week 24, Week 48
Number of Subjects With HIV-1 RNA Levels < 400 Copies/mL or at Least 0.5 Log 10-transformed Decrease From Baseline in HIV-1 RNA Levels
Baseline, Week 24, Week 48
Number of Subjects With HIV-1 RNA Levels < 400 Copies/mL or at Least 1.0 Log 10-transformed Decrease From Baseline in HIV-1 RNA Levels

What clinical trials is Optimized Background Therapy in?

Optimized Background Therapy was studied in one completed Phase 2 clinical trial, NCT00098748. The trial evaluated maraviroc in combination with Optimized Background Therapy versus Optimized Background Therapy alone in 190 antiretroviral-experienced subjects with non-CCR5-tropic HIV-1 infection. The study was randomized, double-blind, and controlled.

Is Optimized Background Therapy the same as maraviroc?

No, Optimized Background Therapy is not the same as maraviroc. In the Phase 2 trial NCT00098748, Optimized Background Therapy was used as the control arm, while maraviroc was the investigational drug added to it. The study compared maraviroc plus Optimized Background Therapy against Optimized Background Therapy alone.
