Purpose
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.
