Comparing pain medicines for menstrual cramps in Crohn’s disease
This study tests two common over-the-counter pain relievers (ibuprofen and acetaminophen) to see which works better for menstrual cramps in women who also have Crohn's disease while in remission. If you have Crohn's and painful periods, this may help you find a safer option.
Chapel Hill, North CarolinaAges 18–44 - NCT04646187Enrolling by invitationPhase 4
Lowering biologic doses for Crohn’s and ulcerative colitis
This trial tests whether people with Crohn’s disease or ulcerative colitis who are currently well-controlled can safely use less-frequent anti-TNF medicine. It may help reduce treatment intensity while keeping inflammation under control.
GhentAges 12–25 - NCT07093294Recruiting
Predicting vedolizumab success with ultrasound in early Crohn's

- How do I know if I qualify for a crohn's disease, active trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a crohn's disease, active trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
