What the trial was testing
The STEPSTONE enrolled 69 patients with crohn's disease. The study was sponsored by Celgene and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was initial testing (phase 2). Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.
What the results showed
39% of patients achieved remission after 12 weeks of taking ozanimod daily.

These findings — that had their Crohn's symptoms go into remission after 12 weeks — were published in the The lancet. Gastroenterology & hepatology and represent the headline result of the study.
Researchers tracked outcomes across 69 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with crohn's disease, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
This was an early-stage study and ozanimod is not yet FDA-approved for Crohn's disease. The results were promising enough that larger studies are now underway. If you have moderate to severe Crohn's disease, ask your doctor about open trials testing ozanimod or other approved treatment options.
Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

68Ga-FAPI-46 PET/CT for Assessing Small Bowel Fibrostenosis in Crohn's Disease
This study is a prospective, case-control study evaluating whether the PET radiotracer 68Ga-FAPI-46 can detect fibrostenosing Crohn's disease in the small bowel. The goal is to determine whether areas of early or developing fibrosis ("pre-stricture" changes) demonstrate uptake of the tracer, which binds to fibroblast activation protein (FAP). Participants with small bowel Crohn's disease will be assigned to either a case or control group based on CT or MR enterography findings at enrollment. Cases will include participants who have a small bowel stricture or probable stricture, with or without penetrating complications. Controls will include participants with small bowel Crohn's disease without strictures. Controls may have active inflammatory disease, luminal narrowing, or no active inflammation (including postoperative or chronic changes), as long as no stricture is present. Because most radiologic strictures represent more advanced fibrostenosis, the study aims to enroll a larger proportion of controls to better characterize early fibrotic changes. Approximately one-third to one-half of participants will be cases, and the remainder controls. This design will allow comparison of FAPI uptake patterns in patients with and without strictures to understand how FAP expression relates to the development of small bowel fibrosis.
Microbial Restoration in Inflammatory Bowel Diseases
This is a prospective, two-centre, double-blind, parallel-arm, randomised, placebo-controlled trial evaluating the impact of FMT on patients with active Crohn's disease.
