Summary

This trial investigates whether a natural product derived from hops is safe and tolerable for people with Crohn's Disease, and whether it produces a biological signature in these patients.

Who is the study for?
Adults aged 21-50 with active Crohn's Disease (CDAI score >150) who are non-smokers, willing to fast before blood draws, collect stool and urine samples bi-weekly, and use reliable contraception if of child-bearing potential. Excluded are those on certain medications or diets recently, hospitalized or had GI surgery within the last 3 months, pregnant women, heavy drinkers/smokers, or using illicit drugs.
What is being tested?
The trial is testing xanthohumol's safety and effects in adults with Crohn's Disease. Participants will take an oral supplement derived from hops for 8 weeks while their biological response is monitored through blood tests, stool samples, and urine collection to understand how gut microbes metabolize it.
What are the potential side effects?
Specific side effects aren't listed but generally include any unexpected reactions to xanthohumol as a natural product. These could range from mild digestive discomfort to allergic reactions; however, part of the study aims to assess overall tolerability.
