Mailing buprenorphine after hospital stay
This study tests whether mailing buprenorphine (a medication for opioid use disorder) to patients after they leave the hospital helps them stay on treatment. If you started buprenorphine in the hospital and are heading home to South Carolina, this option might make it easier to continue your recovery.
Charleston, South CarolinaAges 18 years+ - NCT07402577Recruiting
Pain and opioid use in young sarcoma survivors
This study looks at pain and opioid use in adolescents and young adults who have had sarcoma. It uses a smartphone app to track symptoms over 3 months to better understand cancer-related pain.
Buffalo, New YorkAges 12–70 - NCT07375121Recruiting
Comparing two pain pump settings for mixed surgeries
This study compares two ways of delivering pain medicine through an IV pump (called PCA) after surgery. One method gives a steady dose, and the other slowly reduces the dose. The goal is to see which works better and has fewer side effects.
BeijingAges 18–65 - NCT07365293Recruiting
Support for Families Affected by Opioid or Meth Use
This study tests a program that helps parents who are using opioids or methamphetamines get support for themselves and their families. It may be a good fit if you have Medicaid, live in certain counties, and are open to working with a coach.
Eugene, OregonAges Any age - NCT07354919RecruitingPhase 2
Testing axelopran for advanced cancer patients on opioids
This trial tests if axelopran can help people with advanced prostate, breast, pancreatic, or lung cancer who are taking opioid pain medicines. It aims to see if the drug is safe and helps with bowel function.
Saint Louis Park, MinnesotaAges 18 years+ - NCT07337629Recruiting
Painkiller Before Nose Surgery: Paracetamol vs. Ibuprofen
This study tests whether giving a single dose of paracetamol or ibuprofen before nose surgery can reduce the need for stronger painkillers during and after the procedure. It may help you recover with less opioid pain medicine.
SamsunAges 18 years+ - NCT07334288Recruiting
Numbing injection for pain relief after lower back surgery
This study tests a numbing injection near the spine (retrolaminar block) to reduce pain after lower back surgery with hardware. It could help you use less pain medicine and recover more comfortably.
Santiago, Santiago MetropolitanAges 18–80 - NCT07325279RecruitingPhase 1
Nalmefene Implant Safety Study in Healthy Adults
This trial tests a new implant form of the medicine nalmefene to see if it is safe and well-tolerated in healthy adults. It is an early-phase study that helps researchers understand how the body reacts to the implant before testing it in people with opioid use problems.
Morrisville, North CarolinaAges 18 years+ - NCT06870110Recruiting
Brain training for opioid use disorder
This trial tests a brain-training program for people with opioid use disorder. It uses an EEG headset to measure brain activity while you do computer exercises, and aims to see if this training can help recovery.
Minneapolis, MinnesotaAges 18–65 - NCT07323043Recruiting
Comparing tegileridine and sufentanil for cough during anesthesia
This trial tests whether tegileridine causes less coughing than sufentanil when given as part of anesthesia for surgery. It aims to find a better painkiller option for patients having surgery with a breathing tube.
Lianyungang, JiangsuAges 18–65 - NCT07294118RecruitingPhase 2
Lidocaine and steroids for pain after brain bleed
This trial tests whether giving a numbing medicine (lidocaine) and steroids into the artery that covers the brain can help reduce pain after a brain bleed. It may be an option for people with a specific type of bleeding who have not had certain brain surgeries or procedures.
Galveston, TexasAges 18–100 - NCT07284615Recruiting
Nerve Block vs. Wound Injection for Hip Replacement Pain
This trial compares two pain-relief methods after hip replacement surgery: a nerve block (numbing the hip area) versus a numbing injection into the wound. The goal is to see which provides better pain control.
Cinisello Balsamo, MilanoAges 18 years+ - NCT07276646Recruiting
Pain relief after gallbladder surgery: two nerve blocks compared
This trial compares two anesthetic nerve blocks to see which one reduces the need for opioid pain medicine after gallbladder removal. If you are having laparoscopic gallbladder surgery, this study may help you recover with less pain and fewer opioid side effects.
ZagazigAges 21–64 - NCT07274254RecruitingPhase 3
Lidocaine for sickle cell pain crisis in intensive care
This trial tests whether a numbing medicine (lidocaine) given through a vein can help reduce the amount of strong painkillers (morphine or oxycodone) needed for a sickle cell pain crisis or acute chest syndrome. It aims to ease pain and possibly lower side effects from opioids.
BordeauxAges 18 years+ - NCT07265557Recruiting

- How do I know if I qualify for a opioid 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 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.
