Trial Outcomes & Findings for A Study of Colesevelam for Lenalidomide-Associated Diarrhea (NCT NCT03767257)

NCT ID: NCT03767257

Last Updated: 2025-10-21

Results Overview

To evaluate the ability of colesevelam to improve lenalidomide-associated diarrhea in participants with multiple myeloma treated with lenalidomide maintenance. Diarrhea will be evaluated using Common Terminology Criteria for Adverse Events (CTCAE) grading. The primary end-point is improvement of diarrhea to grade 1 or better according to the CTCAE 5.0 scale by 4 weeks of treatment with colesevelam.
