Enhancing opioid therapy for chronic pain with buprenorphine, counseling, and brain stimulation
This study is testing whether adding a medication (buprenorphine), counseling, and a type of brain stimulation (TMS) can improve long-term opioid therapy for chronic pain. If you have been taking prescription opioids daily for at least 3 months and have extra risk factors for opioid-related problems, this trial may offer you new ways to manage pain and reduce risks.
Charleston, South CarolinaAges 18 years+ - NCT06063902Enrolling by invitation

Common questions
- Are there clinical trials for chronic opioid use?
- Yes. Clin2 currently lists 109 recruiting chronic opioid use studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a chronic opioid use 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 chronic opioid use 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.
