Pilot Study on the Effect of Adding Raltegravir +/- a Second Drug on HIV Levels in the Gut — PLUS  

HIV Infections Clinical Trial

Official title:
A Prospective Longitudinal Pilot Study to Measure the Effect of Intensification With Raltegravir +/- a Protease Inhibitor (PI) or Non-Nucleoside Reverse Transcriptase Inhibitor (NNRTI) on HIV-1 Levels in the Gut

Clinical Trial Summary

The "PLUS" study is a pilot study to measure the effect of therapy intensification (with raltegravir and optional second agent) on HIV levels in the gut and blood in patients on antiretroviral therapy (ART) with viral load < 50 copies/mL (herein referred to as "suppressed"). We hypothesize that there is ongoing replication in the gut despite suppressive ART and that this replication can be inhibited by the addition of one or two new antiretroviral drugs whose activity affects a distinct part of the viral life cycle. All study participants will have upper and lower endoscopy at baseline (before intensification) and after intensification. These endoscopies will be used to obtain gut tissue and single cells (for CD4+ cells) .

Clinical Trial Description

The "PLUS" study is a prospective, longitudinal pilot study to measure the effect of therapy intensification (with raltegravir and possible addition of a study PI or NNRTI-Non-Nucleoside Reverse Transcriptase Inhibitor) on HIV-1 DNA/RNA levels in the gut-associated lymphoid tissue (GALT) and blood in patients on ART with viral load (VL) < 50 copies/mL (herein referred to as "suppressed"). We hypothesize that there is ongoing replication in the GALT despite suppressive ART and that this replication can be inhibited by the addition of one or two new antiretroviral drugs whose activity affects a distinct part of the viral life cycle. All study participants will have a colonoscopy and esophagogastroduodenoscopy (EGD) at baseline (before intensification) and a second colonoscopy with EGD 12 weeks after intensification. These endoscopies will be used to obtain GALT mononuclear cells (for CD4+ lymphocytes) as well as tissue for in situ hybridization and immunohistochemical studies. ;
