Blood test may end guesswork in Crohn's drug choice

NCT ID NCT07363044

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether a simple blood test that reads epigenetic markers can help doctors pick the best biologic drug (ustekinumab or vedolizumab) for adults with active Crohn's disease. 378 participants will be randomly assigned to either have their treatment guided by this test or by standard doctor choice. The goal is to see if the test leads to better remission and fewer side effects.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Epigenetic blood test (EpiPredict) to guide biologic selection (ustekinumab or vedolizumab)
What this could lead to
If successful, this test could help doctors pick the most effective biologic for each Crohn's patient, reducing trial-and-error and improving outcomes.
What could go wrong
This is an early-phase study with 378 participants, so results may not apply to everyone. The test may not reliably predict response, and some patients may still not respond to the chosen drug.
