New study tests ozanimod against standard drug for Steroid-Dependent UC
NCT ID NCT07271069
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at how well ozanimod works compared to azathioprine for people with steroid-dependent ulcerative colitis in Japan. Researchers will review medical records of 150 adults to see which drug helps patients stop steroids and stay symptom-free. The goal is to find a better treatment option for this chronic condition.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Ozanimod and azathioprine
- What this could lead to
- If ozanimod works better than azathioprine, it could offer a more effective way to control ulcerative colitis without long-term steroid use.
- What could go wrong
- This is an observational chart review, not a controlled trial, so results may be less reliable. The study is also limited to Japan, which may not apply to other populations.

Inclusion Criteria: * Participants with Ulcerative Colitis (UC) provided written consent to participate in the study * Participants who are aged ≥ 18 years at the earlier date of either initiation of treatment with ozanimod or azathioprine or obtaining consent * Starting dose of oral steroid ≥ 30 mg/day (prednisolone equivalent) * Administration of ozanimod or azathioprine started after oral steroid administration, and ozanimod or azathioprine administered concomitantly with steroids (excluding patients who started oral steroids and ozanimod or azathioprine on the same day) * In the ozanimod group, patients with notable clinical symptoms due to the primary disease (rectal bleeding subscore ≥ 1 point or total PRO2 score ≥ 2 points) remained at the start of ozanimod administration * In the azathioprine group, patients who started azathioprine treatment after February 2019 Exclusion Criteria: * Participants with symptoms of UC with no change or increase in Patient-Reported Outcome 2 (PRO2) from the time of initiating oral steroid administration after 2 weeks of administration of ≥ 30 mg/day (prednisolone equivalent) of oral steroids * Participants with complications requiring continued steroid use (excluding topically acting steroids for inhalation or topical application) * Participants who participated in other clinical studies involving interventions during the observation period * Participants judged to be inappropriate for enrollment in this study by the investigator at each participating study site
