In Brief

A Phase 4 clinical trial evaluating Crofelemer and Diagnostic tests for cause of chronic diarrhea for Chronic Diarrhea of Unknown Origin. Completed, enrolled 93 participants across 1 site.

Detailed Summary

The purpose of this study is to evaluate the effectiveness of the drug Crofelemer in the treatment of non-HIV patients with chronic idiopathic diarrhea; to determine the prevalence of identifiable causes of chronic diarrhea in a non-HIV patients; to assess the diagnostic yield, in terms of identification of treatable etiologies, of commercially available diagnostic evaluations in adult, non-HIV patients with chronic idiopathic diarrhea, that is, evaluate which tests, among the standard diagnostic tests commonly conducted as part of the evaluation of chronic idiopathic diarrhea, are most likely to identify a treatable cause of the diarrhea; and to analyze the relationship between chronic idiopathic diarrhea and health-related quality of life and assess the impact of crofelemer treatment on health-related quality of life.
