Effects of Crofelemer on the Gut Microbiome in Healthy Volunteers and in HIV+ Patients With Non-Infectious Diarrhea

Summary

This study is intended to evaluate: 1. Any changes in the gut microbiome from baseline compared to end of study in both healthy (HIV-negative) subjects and HIV+ patients with or without chronic diarrhea, following one month of treatment with crofelemer (Mytesi), delayed release 125 mg tablets twice daily (BID) following one month of treatment. 2.
