Recruiting studies
- NCT06084520Recruiting
Pain questionnaire study for opioid and non-opioid patients
This study tests two questionnaires for people with long-term pain. Researchers want to see if the tools work well for both those taking opioids and those who are not. Your answers can help improve pain care.

Brain imaging study for people with opioid use disorder
This study uses a special brain scan (PET) and MRI to look at how a protein in the brain, called CB1 (part of the body's natural pain and reward system), changes when people start treatment for opioid use disorder. It may help doctors understand how buprenorphine works and improve addiction treatments.
New Haven, ConnecticutAges 25–65 - NCT07780097Enrolling by invitation

Study looking for markers of pain and opioid response after injury or surgery
This study is looking for biological markers (like blood tests) that can predict how people will respond to pain and opioids after a traumatic injury or surgery. The goal is to help doctors tailor pain treatment to each person.
La Jolla, CaliforniaAges 18 years+ - NCT07631598Recruiting
Buprenorphine at Needle Exchange Programs to Prevent Overdoses
This study tests whether offering buprenorphine (a medication that reduces cravings and withdrawal) directly at syringe service programs (places where people get clean needles) can help people with opioid addiction stay safe and reduce overdose risk. If you use opioids and visit a syringe service program, this may be an option to explore.
Los Angeles, CaliforniaAges 18 years+ - NCT07490717Enrolling by invitation

Little Rock, ArkansasAges 18 years+ - NCT07486505Recruiting
Mindfulness for pain after arm or leg fracture surgery
This study tests whether brief mindfulness sessions before and after surgery help people manage pain and anxiety while recovering from a broken arm or leg, and may reduce the need for strong painkillers (opioids). It aims to see if this approach is practical and helpful for patients.
Hamilton, OntarioAges 18 years+ - NCT07466784Recruiting
Opioid use registry for emergency patients
This study is for people who come to the emergency department because of an opioid overdose, withdrawal, or related problem. It will collect information about patients' experiences to help improve care and support for opioid use.
Vancouver, British ColumbiaAges Any age - NCT07386769Recruiting
Brain activity during social interaction in opioid use
This study looks at how the brain works during social interactions in people who use opioids regularly. It may help researchers understand how opioid use affects the way you connect with others.
La Jolla, CaliforniaAges 18 years+ - NCT07342504Recruiting
Brief alcohol support for people on buprenorphine
This trial tests a brief alcohol-focused support program designed for people who are already taking buprenorphine for opioid addiction. The goal is to help you reduce your drinking in a way that fits with your current treatment.
Notre Dame, IndianaAges 18 years+ - NCT07218549RecruitingPhase 1
Study of psychoactive substances in people with past opioid use
This trial tests how safe certain psychoactive substances are and what effects they have in people who have used opioids in the past but are not currently dependent on them. It aims to gather information that could help future treatment options.
Houston, TexasAges 18–55 - NCT07214467Recruiting
Adaptive brain stimulation for opioid use disorder
This study tests a new type of brain stimulation that adapts to your brain activity, aiming to reduce cravings and help you control opioid use. It is for people with long-standing opioid use disorder who have not gotten lasting relief from at least 3 treatment attempts, including medication.
San Francisco, CaliforniaAges 22–75 - NCT07197801Recruiting
Peer support program for opioid use disorder treatment
This study tests if a peer recovery support program helps people stay in treatment for opioid use disorder. Participants who recently started medication for opioid use disorder may get extra support from a peer who has been through recovery themselves.
Danville, PennsylvaniaAges 18–89 - NCT07171359Recruiting
TMS therapy for opioid and alcohol use recovery
This trial tests whether TMS (a non-invasive brain stimulation) can improve recovery for people with both opioid and alcohol use disorders. You must be in a specific outpatient program in Portland, Oregon.
Portland, OregonAges 18 years+ - NCT07079826Recruiting
Sparrow Link device for opioid withdrawal in hospital
This trial tests a device placed on the ear to help manage opioid withdrawal symptoms in hospitalized adults. It's for people still having withdrawal despite standard medications or those who've chosen not to take methadone or buprenorphine.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT06981195RecruitingPhase 2
Testing lemborexant for insomnia in people on buprenorphine
This study tests if the sleep medication lemborexant can help people with opioid use disorder who also have chronic insomnia. Participants must already be taking buprenorphine (Suboxone) for at least 4 weeks. The goal is to see if better sleep improves mood and reduces opioid use.
Richmond, VirginiaAges 18 years+ - NCT06872190Recruiting
CDS tool for opioid use disorder in the ED
This trial tests a clinical decision support tool for emergency department providers at UCSF. It helps doctors give better care that considers social needs alongside opioid use treatment. The study will ask providers and patients about how well this tool works.
San Francisco, CaliforniaAges 18 years+ - NCT06823453Recruiting
Training friends and family to support people who use opioids
This study trains friends and family members of people who use opioids, so they can provide better support and reduce stigma. It also includes people who use opioids to see if this training improves their relationship and well-being.
Chicago, IllinoisAges 18 years+ - NCT06800703Recruiting
Opioid use, pain, and the brain
This study uses brain scans (MRI) to understand how pain affects people with opioid use disorder or regular opioid use, compared to healthy volunteers. It aims to find better ways to treat both pain and opioid addiction.
New Haven, ConnecticutAges 21–60 - NCT06726200RecruitingEarly Phase 1
Comparing buprenorphine formulations for fentanyl addiction
This study tests two different forms of buprenorphine (a medication for opioid addiction) to see which works better for people who use fentanyl or other strong synthetic opioids. If you are seeking treatment for opioid use, this trial may help you find the most effective option.
New York, New YorkAges 18–65 - NCT06651177RecruitingPhase 2
Tirzepatide with buprenorphine for opioid use disorder
This study tests whether adding tirzepatide, a medication used for weight and blood sugar, to buprenorphine treatment helps people with opioid use disorder. It aims to see if the combination improves outcomes compared to buprenorphine alone.
Jacksonville, FloridaAges 18 years+ - NCT06651333Recruiting
Brain scans during opioid addiction treatment
This study uses brain scans to understand how methadone or buprenorphine treatment affects the brain, with the goal of helping people stay in treatment and avoid relapse. You would need to be recently started on one of these medications and be able to undergo MRI scans.

Common questions
- Are there clinical trials for opioid use?
- Yes. Clin2 currently lists 280 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.
