Chula Vista, CaliforniaAges 18–60 - NCT07710768RecruitingPhase 1
A study on how UBT251 affects certain drugs in people with extra weight
This study tests if a new medicine called UBT251 changes how the body processes caffeine, midazolam (a sedative), and warfarin (a blood thinner). It is for generally healthy adults with a Body Mass Index (BMI) between 27 and 40.
Cypress, CaliforniaAges 18–65 - NCT05782270RecruitingPhase 4
Blood thinner medicines after bypass surgery with artery unblocking
This trial studies which blood-thinning medicine combination is safest and most helpful after coronary bypass surgery combined with a procedure to unblock the artery (endarterectomy). It focuses on preventing dangerous blood clots while also avoiding excess bleeding.

Common questions
- Are there clinical trials studying Warfarin?
- Yes. Clin2 currently lists 27 recruiting studies that include Warfarin, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Warfarin trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Warfarin an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Warfarin or a specific trial is right for you.
