Gilbert, ArizonaAges 18 years+ - NCT07006675RecruitingPhase 3
NSAIDs for Tibia Fracture Pain and Healing Study
This study tests whether NSAID pain relievers (like ibuprofen) affect bone healing after a broken tibia and if they can help reduce the need for stronger painkillers. If you qualify, you could help doctors learn the safest way to manage pain after this common injury.
Indianapolis, IndianaAges 18–80 - NCT07010978Recruiting
Testing recovery community centers for people on medication for opioid use disorder
This study tests whether recovery community centers (RCCs) help people who are taking medication for opioid use disorder (MOUD) stay in recovery. If you are on MOUD and live near a center that serves a Black community, you may be able to join.
Boston, MassachusettsAges 18 years+ - NCT07024498Recruiting

Common questions
- Are there clinical trials studying Opioid?
- Yes. Clin2 currently lists 443 recruiting studies that include Opioid, 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 Opioid 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 Opioid 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 Opioid or a specific trial is right for you.
