Recruiting studies
- 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 - NCT05556902Recruiting
Testing how epidural spinal cord stimulation may help chronic pain
This study looks at how a device that sends mild signals to the area around your spinal cord may work for long-lasting (chronic) pain. You may be asked to visit a research lab, have blood taken, and follow the study plan so researchers can understand the treatment’s effects.
Birmingham, AlabamaAges 18–89 - NCT05580419Recruiting
Program training to improve chronic pain care
This trial tests whether a 4PCP training program for primary care clinicians improves both clinician and patient outcomes for people living with chronic non-cancer pain. If you have long-lasting pain and can take part in questionnaires and visits, your participation may help evaluate whether this program leads to better care and results.
Cleveland, OhioAges 14–80 - NCT05585229RecruitingPhase 2
Psilocybin therapy to help you taper opioid pain medicine
This Phase 2 study tests a structured, therapist-led treatment using standardized natural psilocybin to help people reduce or stop long-term opioid use for chronic (non-cancer) pain. It’s mainly for those who have tried tapering before but couldn’t, and who are motivated to try again.
Kelowna, British ColumbiaAges 19–75 - NCT05592132Recruiting
Virtual reality to help children handle cancer treatment pain
This trial studies whether virtual reality can reduce pain and discomfort during painful medical procedures for children getting care for benign (non-cancerous) tumors or cancer. It may help make treatments feel easier for you and your child during procedures.
Saint-DenisAges 6–18 - NCT05596591Recruiting
Shockwave treatment for knee arthritis pain with MRI-confirmed lesions
This trial tests whether focused shockwave therapy (a non-surgical treatment) can reduce knee arthritis pain. It specifically targets people whose MRI shows a small bone problem in one area of the knee.
Cedar Knolls, New JerseyAges 30–80 - NCT05635929Recruiting
Topical treatment to reduce mouth sores during or after radiation
This study tests a new cream/gel applied to the mouth to lower the chance of severe mouth sores in people receiving radiation for head and neck cancer. It also looks at how treatment affects quality of life using patient questionnaires.
Madrid, MadridAges 18 years+ - NCT05641948Recruiting
Tested nerve ablation plus brain scans for ongoing back pain
This trial studies a procedure called radiofrequency denervation to reduce long-lasting, mostly “pain-from-joints/structures” low back pain, and it uses brain imaging to understand what changes during treatment. It may help people who already showed they respond well to a similar diagnostic nerve block.
Aberdeen, ScotlandAges 18 years+ - NCT05648253Recruiting
Hyivy device after pelvic radiation for vaginal health
This study checks whether a special vaginal device (Hyivy) is safe and workable after pelvic radiation for certain cancers. You may be asked to use it for 12 weeks to help with vaginal changes after treatment, and you would visit the study team regularly.
Kitchener, OntarioAges 18 years+ - NCT05658575RecruitingPhase 2/Phase 3
Tablets to treat sudden gout flare pain
This trial studies dapansutrile tablets (OLT1177) to see how well they work for people in the first 4 days of an acute gout flare. It may help reduce pain and inflammation in the specific joint where your gout is flaring.
Birmingham, AlabamaAges 18 years+ - NCT05661903RecruitingPhase 2
Spinal cord stimulator study for nerve pain and brain effects
This Phase 2 study looks at how spinal cord (or nerve-root) stimulation affects pain signals in the brain and body. You may qualify if you already have a stimulator set to a comfort mode that avoids “tingling” sensations.
Boston, MassachusettsAges 18–80 - NCT05662371Recruiting
Testing pain-monitor guided pain medicine during robot bowel surgery
This study checks whether using a pain-activity monitor during robot-assisted colorectal surgery can help the surgical team choose the right pain medicine. It may improve comfort and reduce the chance of giving too much or too little pain medicine.
AabenraaAges 18–80 - NCT05663684RecruitingPhase 4
Topical numbing drops to reduce pain during tear duct testing
This Phase 4 trial studies whether numbing eye drops (proparacaine 0.5%) can reduce pain during a procedure called probing and irrigation of the tear drainage system. If you need this test for ongoing watery eyes, the trial may help make the procedure more comfortable.
New Orleans, LouisianaAges 18 years+ - NCT05672784Recruiting
Knee numbing injections during knee replacement surgery
This trial compares two ways of numbing a knee area during planned knee replacement surgery: a nerve block alone versus a nerve block plus additional numbing medicine near the back of the knee. It may help doctors find which approach improves pain control and recovery while keeping side effects low.
ZagazigAges 21–60 - NCT05674357Recruiting
Training therapists to help people with cancer distress
This trial trains therapists in evidence-based treatments to reduce distress related to cancer and cancer care. You may be able to join if you’re being treated or followed at MGH Cancer Center and your distress level is high.
Boston, MassachusettsAges 18 years+ - NCT05688904RecruitingPhase 1
Topical imipramine with light treatment for skin pain relief
This Phase 1 study tests whether applying imipramine cream to the skin affects pain and effectiveness when combined with a light-based skin treatment (photodynamic therapy). It’s mainly looking at safety and early signs of benefit for people with certain sun-damaged skin areas.
Fairborn, OhioAges 18 years+ - NCT05697159Recruiting
7-tesla brain MRI to study how filgotinib eases RA pain
This trial uses a very high-strength brain MRI to understand how the RA medicine filgotinib may reduce pain. If you have active rheumatoid arthritis and can safely complete the scan, the study may help researchers better target pain relief in RA.
GlasgowAges 18–74 - NCT05712395Recruiting
Pain-free exercise program for people with leg artery disease
This trial tests a new kind of exercise that is meant to be non-ischemic (not reduce blood flow) and pain-free, to see if it helps people with peripheral artery disease (PAD) who get leg pain when walking. You may be eligible if you have PAD confirmed by specific treadmill and blood-pressure measurements and meet the exercise and health safety requirements.
Oklahoma City, OklahomaAges 40 years+ - NCT05722002RecruitingPhase 4
Compare pain-med plans after low-risk surgery
This study tests which pain-medication plan works best and has the fewest side effects after certain low-risk surgeries. You may be assigned to receive opioid-based, NSAID-based, or acetaminophen-based pain control depending on your situation.
Ann Arbor, MichiganAges 18 years+ - NCT05726786RecruitingPhase 3
