Assessing switching to long-acting buprenorphine injection in jail
This study tests whether switching from daily buprenorphine/naloxone (Suboxone) to a long-acting injectable buprenorphine (XRB) is safe and effective for men who are unsentenced and in jail for at least 4 days. It aims to see if the injection can help continue treatment without needing daily medication.
Boston, MassachusettsAges Any age - NCT06270147RecruitingPhase 2
Timing of nerve blocks for weight loss surgery pain
This trial tests whether giving a nerve block before or after bariatric surgery works better for pain control. It could help you have less pain and use fewer painkillers after your procedure.
Hamilton, OntarioAges 18 years+ - NCT06291363RecruitingPhase 4
Esmolol for pain control during laparoscopic surgery
This trial tests a drug called esmolol to see if it helps control pain during and after laparoscopic surgeries that involve a small cut below the belly button. It may help people having a hysterectomy or left colon removal feel less pain during anesthesia.
Montreal East, QuebecAges 18–65 - NCT06584201Recruiting
Pain block effects on lung function after surgery
This study compares two types of nerve blocks given before surgery to see how they affect your breathing and lung function right after the operation. It is for adults having certain procedures who are generally healthy or have mild to moderate health conditions.
IstanbulAges 18–65 - NCT06639438Recruiting
Sensory outcomes in people who use opioids
This study looks at how opioids affect the senses in people having planned surgery. Researchers want to compare patients who use opioids (for pain or addiction) with those who don't, to see if there are differences in sensation.
Boston, MassachusettsAges 18 years+ - NCT06877858RecruitingPhase 1
MethaLoad dose-finding study for opioid use disorder
This study tests a new way to start methadone treatment (called 'MethaLoad') for people with opioid use disorder who have used fentanyl. If you qualify, you will receive methadone to help manage withdrawal and reduce cravings, and the doctors will closely monitor your safety and response.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06909851Recruiting
Comparing nerve blocks for pain after knee arthroscopy
This study compares two different types of nerve blocks to see which provides better pain relief after arthroscopic knee surgery. You will receive one of the blocks after your surgery, and your pain levels will be tracked.
IstanbulAges 18–72 - NCT06992427RecruitingPhase 3
Gabapentin to prevent opioid use for mouth pain during cancer treatment
This trial tests if taking gabapentin during chemoradiation for head and neck cancer can reduce the need for strong painkillers like opioids. It may help manage mouth pain caused by treatment.
Gilbert, ArizonaAges 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 - NCT07447856RecruitingPhase 1
Herbal plasters for pain relief while using opioids
This trial tests a topical herbal plaster to see if it can help reduce pain in people with cancer who are already taking opioids. The plaster is placed on the most painful area and may allow you to use less opioid medication.
Basking Ridge, New JerseyAges 18 years+ - NCT07215546Enrolling by invitation
Stopping pain after heart surgery with a special chest closure
This trial tests a new device to close the breastbone after open-heart surgery to see if it helps reduce the need for prescription pain medicine. The device is designed to hold the bone together more securely, which may lead to less pain and faster recovery.
Naples, FloridaAges 19–80 - NCT06139666Enrolling by invitationPhase 4
Liposomal bupivacaine nerve block for rotator cuff surgery
This study tests whether a long-lasting numbing medicine called liposomal bupivacaine (Exparel) works better than standard pain relief for people having rotator cuff surgery. It aims to lessen pain after surgery so you may need fewer pain pills.
Camden, New JerseyAges 18 years+ - NCT06077422Enrolling by invitationPhase 2/Phase 3
Comparing two pain blocks for heart surgery recovery
This trial compares two types of pain blocks (Exparel vs. Marcaine) given during heart surgery to see which one provides better pain relief. If you are scheduled for a heart surgery through a small or full chest incision, you may be able to join.
New Brunswick, New JerseyAges 18 years+ - NCT06574009RecruitingPhase 4
Better options for chronic cancer pain in veterans

Indianapolis, IndianaAges 18–99 - NCT05555485Recruiting
Check if ear stimulation can help chronic pain and reduce opioids
This study tests whether a device that stimulates the ear (through the skin) can reduce chronic pain and help people lower their opioid pain medicine. It may help you manage pain with less opioid use if you meet their safety and medication criteria.
Galveston, TexasAges 18–65 - NCT07228377Recruiting

Washington D.C., District of ColumbiaAges 18 years+ - NCT07457489Recruiting
Brain stimulation for opioid recovery
This study tests a non-invasive brain stimulation technique called TMS to see if it can reduce opioid cravings and help people who are already taking buprenorphine stay in recovery. TMS uses magnetic pulses to stimulate parts of the brain involved in addiction.
Brentwood, TennesseeAges 18–65 - NCT06706375Recruiting
