Baltimore, MarylandAges 18–100 - NCT05199870Enrolling by invitation
Long-term follow-up for specific hip implant parts
This study follows people who had a particular bipolar hip implant (RingLoc cup and/or Endo II head) placed during a hemi-hip replacement surgery at least 8 years ago. It checks how well the implants keep working over time and why.
Falls Church, VirginiaAges 18 years+ - NCT05068791RecruitingEarly Phase 1
Psilocybin-assisted treatment for long-term body pain
This early trial studies whether psilocybin, given in a supported setting, can reduce long-term widespread musculoskeletal pain (including fibromyalgia-like symptoms). You would be monitored closely and need someone to take you home after the medicine session.
Birmingham, AlabamaAges 25–65 - NCT04939623RecruitingPhase 2
Probenecid to ease opioid withdrawal symptoms while tapering
This Phase 2 study tests whether probenecid can lessen discomfort from opioid withdrawal in adults who are gradually lowering their opioid pain medicine. If it works, it may make tapering feel more tolerable and safer.
Calgary, AlbertaAges 18–80 - NCT04995224Recruiting
Study what causes long-term pain in new Crohn’s or colitis
This study looks at why some people develop long-term pain after being newly diagnosed with ulcerative colitis or Crohn’s disease. It may help researchers understand the pain process and improve future treatments.
LondonAges 18 years+ - NCT03876054Recruiting
Tracking outcomes after Abbott neurostimulator implantation
This study follows people long-term after they get an Abbott device implanted to help with chronic pain. It aims to learn how well the therapy works in real-world care over time.
Phoenix, ArizonaAges 18 years+ - NCT04379115Recruiting
Brain stimulation study for people with opioid addiction
This study tests a non-invasive brain stimulation approach to reduce opioid cravings in people who are actively using non-prescribed opioids while on stable methadone. It may help people feel less craving and improve recovery support.
Hinsdale, IllinoisAges 18–85 - NCT04441034RecruitingPhase 4
Compare two medicines for long-term pain in real life
This trial compares two types of medicines—anti-convulsants and anti-depressants—for people with persistent pain lasting more than 3 months. It aims to find out which option works better in everyday care and for which patients.
Redwood City, CaliforniaAges 18 years+ - NCT04206215Recruiting
Noninvasive brain stimulation for carpal tunnel pain relief
This study tests whether a noninvasive brain stimulation treatment can reduce chronic carpal tunnel (CTS) pain, especially when pain spreads beyond the usual nerve area. If you have long-lasting CTS pain that hasn’t improved with standard treatments, you may be able to try this therapy while being closely monitored for safety.
