Safety and Effectiveness of 3 Doses of Crofelemer Compared to Placebo in the Treatment of HIV Associated Diarrhea (ADVENT)
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
This is a randomized, double-blind, parallel-group, placebo-controlled, multi-center study. This study will compare an investigational new drug (crofelemer) to placebo for the control of HIV-associated diarrhea. The first stage of the study will determine the optimal dose of study drug based on safety and response to therapy and the second stage will evaluate further the effectiveness of the optimal dose.
The primary objective is to determine the proportion of HIV-positive subjects experiencing relief of diarrhea with crofelemer compared to placebo during the placebo-controlled treatment phase. [ Time Frame: 31 days ]
Primary efficacy outcome is two or less watery bowel movements per week during at least two weeks of the treatment phase. [ Time Frame: 31 days ]
