Pilot Study of Maraviroc/Raltegravir for Naive HIV-1 Patients

• Status: Unknown status
• Trial end date: 2015-12-01
• Target enrollment: 0
• Participant gender: All

Summary

Background and Rationale

Raltegravir and Maraviroc, the first in class of 2 new families of antiretroviral drugs have demonstrated a high potency in treatment experienced and naive patients. Both drugs appeared well tolerated with low metabolic toxicity. No data are currently available concerning the combination of these 2 drugs.

Hypothesis

Maraviroc + Raltegravir should be potent enough to maintain virological efficacy in naive patients infected by CCR5 HIV-1 previously treated for 6 months with a Maraviroc-Raltegravir-Tenofovir-Emtricitabine combination.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Association Pour la Recherche en Infectiologie
• Treatments: Emtricitabine; Maraviroc; Raltegravir Potassium; Tenofovir
