Comparing Buprenorphine pill vs injection for opioid use disorder
This study compares two forms of a medication called buprenorphine (one is a pill you take under the tongue, the other is an injection) to see which works better for treating opioid use disorder. If you are eligible, you will receive one of these forms for a year and regular check-ups.
Tuscaloosa, AlabamaAges 18 years+ - NCT04354077Recruiting

Toronto, OntarioAges 18 years+ - NCT04197921Recruiting
Brain-focused ultrasound for opioid addiction-related substance use

Tampa, FloridaAges 18–60 - NCT03720613Recruiting
Testing medicines to prevent heart events in opioid constipation
This study looks at how well naldemedine (and certain other constipation medicines) lower the risk of major heart problems in people who take opioids for constipation. It compares medicine use patterns in people with opioid-induced constipation to see who has fewer serious heart events.
Wilmington, DelawareAges 18 years+ - NCT03396276Enrolling by invitationPhase 4
Emergency system to help people stop opioid misuse
This Phase 4 study tests an “emergency opioid engagement system” that aims to help people who are opioid-dependent start stopping opioid use. If you’re willing to stop and can safely participate, the program may offer structured support when you’re in the emergency setting.

Testing for HIV in opioid treatment programs
This project studies how to improve offering and completing HIV (and hepatitis C) tests in opioid treatment programs. It may help increase timely follow-up and linkage to care when results are positive.
New York, New YorkAges 18 years+ - NCT06995885Enrolling by invitation
A study to improve tracking of opioid use in the fentanyl era
This study aims to develop a better tool for recalling and tracking opioid use patterns, especially with fentanyl. It may help people who use opioids outside of medical settings to more accurately report their use.
Baltimore, MarylandAges 18–99 - NCT04166071Enrolling by invitationEarly Phase 1
Testing whether opioids plus support change learning behavior
This early study tests how opioid medicine, along with social support, affects how people learn or “unlearn” certain responses. If you’re healthy and meet safety requirements, it may help researchers understand how support could change the effects of pain-related medicines on behavior.
Los Angeles, CaliforniaAges 18–35 - NCT07813026RecruitingPhase 4
Combining gabapentin and oxycodone: abuse effects in recreational users
This study looks at how the combination of gabapentin and oxycodone affects feelings of reward or abuse (like euphoria) in healthy people who have used opioids recreationally. It helps understand if this combination might be more or less abusable.
Overland Park, KansasAges 18–55 - NCT07846722Recruiting
Comparing two medicines to reduce pain medicine use after laparoscopic hysterectomy
This study compares two drugs, esmolol and dexmedetomidine, to see which one better reduces the need for strong painkillers after laparoscopic hysterectomy. It may help you manage pain with fewer opioids.
AthensAges 20–70 - NCT07840183RecruitingPhase 4
Epidural versus other pain relief for open ventral hernia repair
This study compares two ways to manage pain after hernia repair surgery: using an epidural (a small tube in your back that delivers pain medicine) versus other pain medications that aim to reduce opioid use. The goal is to see which method provides better pain relief and helps you recover more comfortably.
Chicago, IllinoisAges 18–80 - NCT07793383Recruiting
Testing ways to support opioid treatment decisions in the ER
This study is testing different ways to help people with opioid use disorder decide if they want to start medication treatment while they're in the emergency department. It's looking at how to improve the support and guidance given in that setting.
Guilford, ConnecticutAges 18 years+ - NCT07778394Recruiting
Smartphone app to support recovery from opioid use disorder
This study is testing a smartphone app to help people who are starting or restarting medication for opioid use disorder. If you join, you'll use the app to support your recovery journey.
Providence, Rhode IslandAges 22 years+ - NCT07768007Recruiting
Methadone and memory study for opioid use disorder
This study tests whether a new approach can improve memory and mood in people taking methadone for opioid use disorder. It involves brain scans and may help with feelings of sadness or loss of interest.
New Haven, ConnecticutAges 18–50 - NCT07734623Recruiting
Ultrasound treatment for severe opioid or amphetamine use disorder
This trial tests a low-intensity focused ultrasound treatment for people with severe opioid or amphetamine use disorder. The ultrasound targets a part of the brain linked to addiction, and the goal is to see if it is safe and helpful.
TaipeiAges 20–50 - NCT07709975Recruiting
Pain relief and early movement for older ICU patients

Common questions
- Are there clinical trials studying Opioid?
- Yes. Clin2 currently lists 430 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.
