Recruiting studies
- NCT05877157Recruiting
Study how pain and opioids change after surgery
This study follows adults in the hospital after surgery to understand how pain and opioid (strong pain medicine) use affect them. Your answers on questionnaires help researchers see what happens after different types of anesthesia.
Zagreb, Vinogradska 29Ages 18 years+ - NCT07420283RecruitingPhase 2
Study of Brenipatide for opioid use disorder
This trial tests a new medicine called Brenipatide for people with opioid use disorder who are already taking buprenorphine but still occasionally use non-prescribed opioids. It aims to see if the study drug can help reduce opioid use.
Phoenix, ArizonaAges 18–75 - NCT07408193RecruitingEarly Phase 1
Lidocaine and ketamine for severe cancer pain not helped by opioids
This trial tests if adding lidocaine and ketamine to your current pain medicines can better control severe cancer-related pain that opioids alone haven't helped.
Athens, AtticaAges 18 years+ - NCT05985850RecruitingPhase 2
Can cannabis help with opioid addiction treatment?
This trial tests if adding a specific cannabis product to standard methadone treatment helps people with opioid use disorder. It's for adults over 25 who recently started methadone and have used cannabis before.
Vancouver, British ColumbiaAges 25 years+ - 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+ - NCT07361822Recruiting
Opioid use after surgery: standard vs smart pump
This trial compares two ways to give pain medicine through an IV pump after surgery. It tests if a smart pump that adjusts the dose based on feedback works better than a standard pump that delivers a steady, fixed dose. This might help patients use less opioid pain medicine.
BeijingAges 18–65 - NCT07364864Recruiting
Opioid-free anesthesia for pancreas surgery
This study tests whether avoiding opioids (strong painkillers) during surgery for pancreas or duodenum cancer can lead to a smoother recovery. If you are having a large incision in your belly for this surgery, you might be able to use only regional anesthesia and other non-opioid medicines.
Krakow, Lesser Poland VoivodeshipAges 18–80 - NCT07362082Recruiting
Telehealth treatment for opioid use disorder
This study tests whether treatment for opioid use disorder can be done effectively through telehealth (video calls and texts). It is designed for people who are not currently on medication for opioid addiction and want to start treatment from home.
New Haven, ConnecticutAges 18 years+ - NCT07350148Recruiting
Text messages to support opioid medication adherence
This study tests whether daily supportive text messages help people stay on track with their methadone or buprenorphine treatment for opioid use disorder. It is designed for adults who recently started or resumed this medication and have a cellphone.
Albuquerque, New MexicoAges 18 years+ - NCT06595329RecruitingPhase 1
Pain relief after kidney cancer surgery: epidural vs spinal opioids
This trial compares two ways to manage pain after open kidney cancer surgery: an epidural (a thin tube placed near your spine) versus a single spinal injection of opioids. Both aim to control pain, but the study wants to see which method works better, with fewer side effects.
SplitAges 18 years+ - NCT07318480Recruiting
Brain stimulation for drug addiction
This study tests a type of brain stimulation (called tDCS) to help people reduce their use of stimulants (like crack/cocaine) or opioids. It might help lessen cravings and improve treatment outcomes.
New York, New YorkAges 18–60 - NCT07315308Recruiting
Nerve block before heart surgery and painkiller use
This study tests whether a numbing injection in the chest before heart surgery can reduce the amount of pain medicine needed during the operation. It may help you manage pain better and recover more comfortably.
Gaziantep, SahinbeyAges 18–65 - NCT07278375Recruiting
Comparing treatments for babies with opioid withdrawal
This study looks at different medicine approaches to treat newborns with opioid withdrawal (NOWS). It compares how well babies do with standard care and may help find the best way to manage symptoms and support recovery.
Birmingham, AlabamaAges birth+ - NCT07278518Recruiting
Emergency department decision aid for buprenorphine
This trial is testing a tool to help people in the emergency department decide whether to start buprenorphine (a medication for opioid use disorder). It's for patients who are not already on medication for their condition.
Charleston, South CarolinaAges 18 years+ - NCT07264556Recruiting
Comparing three anesthesia types for colorectal cancer surgery
This trial compares three types of anesthesia during colorectal cancer surgery to see how they affect the body's immune response and cancer cells. It may help find the safest and most effective anesthesia option for people having this operation for the first time.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT07232641Recruiting
How pandemic rules affected opioid addiction treatment in the VA
This study looks at how changes in federal and state rules about medications for opioid use disorder during the pandemic affected veterans. It uses information already in your VA records, so there are no extra visits or tests needed.
Boston, MassachusettsAges 18 years+ - NCT07226570Recruiting
Ibogaine brain mapping study for opioid use disorder
This study uses MRI and EEG scans to map how ibogaine affects the brain in people with opioid use disorder. You must already be scheduled to receive ibogaine treatment in Tijuana, Mexico, on your own, as the study does not cover treatment costs.
Irvine, CaliforniaAges 21–70 - NCT07227389Recruiting
Opioid Timing and Breathing Risk After Surgery
This study looks at when opioids are given during surgery and how it affects breathing problems after surgery. It might help understand how to make pain control safer.
Detroit, MichiganAges 18–85 - NCT07226700RecruitingPhase 3
Suzetrigine for pain after hip replacement surgery
This study tests an investigational pain medicine called suzetrigine to see how well it controls pain after total hip replacement surgery. It is for adults 18–80 who are having a first-time hip replacement and can receive spinal anesthesia.
New York, New YorkAges 18–80 - 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 - NCT07178262RecruitingPhase 4
Nerve block to reduce pain medicine after hysterectomy
This study tests whether a nerve block (an injection near the spine) can help reduce the amount of strong pain medicine you need after a hysterectomy. The goal is to see if it leads to fewer side effects and a smoother recovery.
Islamabad, FederalAges 16–80 - NCT07169409RecruitingPhase 1
