Rockville, MarylandAges 18–65 - NCT05495984Recruiting
Brain change study for mothers in opioid treatment
This study looks at whether supportive interventions can affect brain “plasticity,” or how the brain adapts, in mothers who are in treatment for opioid use disorder. If you qualify, you may be asked to take part in assessments and follow-up so researchers can better understand recovery during early motherhood.
New Haven, ConnecticutAges 21–45 - NCT05511909RecruitingPhase 2

Rochester, New YorkAges 18 years+ - NCT06521476RecruitingPhase 2
Acetazolamide for sleep apnea in people on opioid treatment
This trial tests if a drug called acetazolamide can help people with central sleep apnea who are also on medication for opioid use disorder. Sleep apnea causes breathing to stop during sleep, and this study aims to see if the drug improves their sleep breathing.
Pittsburgh, PennsylvaniaAges 18–100 - NCT06527820Recruiting
Talking about buprenorphine and methadone for opioid use
This trial is testing a conversation approach to help people start medication for opioid use disorder (like buprenorphine or methadone). It may be a good fit if you've had an overdose, opioid withdrawal, or other serious problem from opioid use and are not already on these medications.

- Yes. Clin2 currently lists 287 recruiting 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 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 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.
