Integrase Inhibitor (MK-0518) Viral Decay

HIV Infections Clinical Trial

Official title: Effect of Integrase Inhibitor (MK-0518) on Decay of Low Level Viral Replication in HIV Reservoirs in Infected Individuals Who Initiated Conventional Antiretroviral Therapy During the Chronic Phase of Infection

Status Completed

Clinical Trial Summary

The eradication of HIV by antiretroviral therapy has thus far been elusive. It has been consistently demonstrated that a pool of latently infected, resting CD4+ T cells persists in the majority of HIV-infected individuals receiving antiretroviral therapy in whom plasma viremia has been successfully suppressed for prolonged periods of time; this pool has emerged as the major obstacle in achieving the eradication of HIV. We believe that MK-0518 can further the decay and suppression of HIV-1 in patients who have been virologically suppressed for a prolonged period of time on effective cART (≥ 4 years).

Clinical Trial Description

The trial is a prospective, double-blind, randomized, placebo-controlled study with two phases: phase I to 48 weeks and phase II to 96 weeks with the primary analysis at 48 weeks. HIV-infected individuals who are taking their first standard cART regimen for at least four years with complete viral suppression. Upon enrollment, he/she will be randomized to one of two arms: the MK-0518 arm or the control arm. As each participant reaches week 48, he/she will be unblinded and those in the MK-0518 arm will continue taking MK-0518. Based on the results of an interim analysis, the control arm will be rolled over to receive MK-0518 for 48 weeks. After the screening, baseline visits and week 4 safety visit, follow-up visits will occur every 8 weeks for both arms. ;
