Recruiting studies
- NCT04379115Recruiting

Loratadine to reduce bone pain during stem cell collection
This early trial studies whether loratadine (an allergy medicine) can reduce bone pain caused by G-CSF, which is used to help your body collect stem cells. If you have multiple myeloma and are preparing for stem cell mobilization, this may make treatment-related bone pain more tolerable.
New Brunswick, New JerseyAges 18 years+ - NCT04214561Enrolling by invitation
Studies how sleep measures relate to teeth grinding
This study looks at sleep testing results to understand what relates to sleep bruxism, which is teeth grinding or clenching during sleep. It may help researchers better understand the causes and patterns behind this condition.
WroclawAges 18–70 - NCT04218617RecruitingPhase 2
One vs two radiation treatments for spine metastases
This trial tests whether giving radiation to a spine metastasis in one dose works as well as giving it in two smaller doses. It aims to control tumors while keeping side effects and risk to the spinal cord low.
Cleveland, OhioAges 18 years+ - NCT04251429Enrolling by invitation
Healthy workplace program for public healthcare workers
This trial studies a workplace program delivered by trained peers to improve health in public-sector healthcare facilities. You may be able to join if you are a direct employee of the agency that runs the facility.
Ages 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.
Charlestown, MassachusettsAges 18–80 - NCT04028687Recruiting
Study of a hip stem used in select adult hip replacements
This trial follows people who have had a hip replacement using a specific “Taperloc Complete” stem. It is meant to monitor outcomes after surgery and see how well the stem performs over time for certain non-infectious hip problems.
Henderson, NevadaAges 18 years+ - NCT04040452RecruitingPhase 4
Continuous versus intermittent ketorolac for kids’ heart surgery pain
This study compares two ways of giving ketorolac (a pain medicine) to young children after heart surgery—continuous drip versus doses at set times. It aims to find which approach controls pain better with fewer side effects.
Phoenix, ArizonaAges 3 months–4.9 years - NCT04085848Recruiting
Music program for suicidal thoughts and emotional pain
This trial tests whether listening to music can help reduce psychological pain and suicidal mood during a short stay in a psychiatric hospital. You would be asked to stay in the hospital for about 48 to 60 hours and complete study steps after giving consent.
Saint-PaulAges 18 years+ - NCT04094701Recruiting
Study of opioid needs after hip arthroscopy surgery
This study looks at how much pain medicine (opioids) people actually need after hip arthroscopy and what factors may affect it. It may help improve safer, more personalized pain control after surgery.
Chicago, IllinoisAges 18–80 - NCT04003272Enrolling by invitation
Reverse shoulder implant study for severely damaged rotator cuff
This trial studies a specialized reverse shoulder implant system for people whose rotator cuff is badly damaged or who had a prior shoulder replacement that failed. It aims to reduce pain and improve function by improving how your shoulder works, especially when the rotator cuff can’t do its job.
Louisville, KentuckyAges 18 years+ - NCT04003311Enrolling by invitation
Follow-up for specific shoulder implant types and surgery
This study checks outcomes in people who already received certain Zimmer Biomet shoulder implant components using the correct surgical technique. It may help improve how these specific implants are used and monitored after surgery.
Boise, IdahoAges 18 years+ - NCT04025359RecruitingEarly Phase 1
Test dronabinol for pain responses in people on opioid treatment
This early-stage study tests whether dronabinol (a form of THC) changes pain perception in people with opioid use disorder who are already stable on methadone or buprenorphine. It may help researchers understand whether this treatment affects pain and drug-related outcomes in a safer, controlled way.
West Haven, ConnecticutAges 18–70 - NCT03952299RecruitingPhase 3
Oxybutynin patch after bladder surgery for children’s urgency pain
This study tests whether an oxybutynin skin patch after bladder surgery can reduce bladder pain and urgent, frequent urination in children. It compares symptoms after surgery to see if the patch helps more than the control plan.
Sacramento, CaliforniaAges 4–8 - NCT03794362Recruiting
Testing how pain medicines change pupils in children
This study looks at how different pain treatments affect a child’s pupils (the dark center of the eye). It may help doctors better understand which pain medicines are working and how to measure pain treatment effects more accurately.
Washington D.C., District of ColumbiaAges 7–21 - NCT03867539RecruitingPhase 4
Numbing shot and education to reduce opioids after carpal tunnel surgery
This study tests whether giving a long-lasting numbing injection (Exparel) plus education about pain management can help people avoid taking opioid pain pills after carpal tunnel release surgery. It may help reduce opioid use while still supporting comfort during recovery.
Dayton, OhioAges 18 years+ - NCT03759028RecruitingPhase 4
Study of pain relief after elbow fracture surgery
This trial looks at how well different pain medicines work after surgery for a specific type of broken elbow bone. It may help find a safer, more comfortable pain-control plan while the fracture heals.
Los Angeles, CaliforniaAges 4–12 - NCT03796572RecruitingPhase 4
Nerve-block pain relief after a specific elbow bone fracture
This trial studies whether a pain-relief “nerve block” with medicine helps control pain after surgery for a particular type of elbow (humerus) fracture. It may help you feel more comfortable during recovery, compared with standard pain control.
Los Angeles, CaliforniaAges 4–12 - NCT03834818Recruiting
Using a phone app to track pain after orthopedic surgery
