A Phase 2 Clinical Trial: Xanthohumol Metabolism and Signature (XMaS) in Crohn's Disease

Running, not enrolling · Phase 2 · Has a placebo group

Conditions studied: Crohn Disease

In brief

A pilot study to assess the safety and tolerability of an orally administered natural product derived from hops, called xanthohumol, in humans with Crohn's Disease, in order to identify a biological signature of xanthohumol exposure, and to characterize the role of xanthohumol metabolism by intestinal microorganisms in that signature within adults with Crohn's Disease.
