- NCT05840562RecruitingPhase 3
Capsaicin skin patch vs duloxetine for nerve pain after chemo
This Phase 3 trial tests whether a capsaicin patch works better than duloxetine tablets to reduce painful nerve pain after chemotherapy. It aims to help people whose “gloves and socks” nerve pain has lasted after chemo.
AngersAges 18 years+ - NCT05818774Recruiting
Different types of neck nerve ablation for chronic pain relief
This trial compares two ways of using radiofrequency heat to treat a specific set of neck pain nerves (the “cervical medial branch nerves”). It may help people with long-lasting neck pain who did not improve with standard treatments and who respond to diagnostic nerve blocks.
Toronto, OntarioAges 18–85 - NCT05843890Recruiting
Personalized pain guide for chronic low back pain
This study tests a tailored (personalized) pain guide to help people with long-lasting lower back pain. It may help by teaching strategies to reduce how pain interferes with daily life.
Ann Arbor, MichiganAges 18 years+ - NCT05816174Recruiting
Study of long-term pain after bone surgery in children
This study follows children and teens to learn how pain can last after planned orthopedic (bone) surgery in the hospital. It may help doctors better understand which kids are more likely to have long-lasting pain and how to support them.
BaselAges 8–18 - NCT05830630Recruiting
Methylene blue given during leg amputation surgery
This trial studies whether infusing methylene blue during above- or below-knee leg amputation can improve outcomes for people with poor blood flow to the legs. It targets patients having surgery under general anesthesia, while excluding those with certain allergies or blood clotting problems.
Tanta, Gharbia GovernorateAges 18 years+ - NCT05821517RecruitingPhase 4
Breathing or virtual reality to treat shoulder dislocation pain
This trial compares two ways to help control pain after an anterior (front) shoulder dislocation: methoxyflurane breathing and a virtual reality headset, versus usual pain treatment. It may help some people by making pain control easier during treatment.
NiceAges 18 years+ - NCT05814497Recruiting
Brain scan study of how kids process chronic pain
This study looks at how the brain processes pain sensations in children with certain long-lasting pain conditions. It may help researchers understand what’s happening in the nervous system and guide better treatments.
Cincinnati, OhioAges 10–17 - NCT05833048Recruiting
Pain-relief nerve block during cardiac surgery
This study tests whether a numbing “nerve block” placed in the rectus sheath area can reduce pain for people having certain heart surgeries with chest tubes. If you qualify, it may help your comfort during recovery, but it also depends on how suitable you are for local anesthesia.
New York, New YorkAges 18–85 - NCT05790239RecruitingPhase 2
MDMA therapy sessions for veterans with PTSD
This Phase 2 trial tests whether therapy assisted by MDMA can reduce symptoms of moderate to severe post-traumatic stress disorder (PTSD) in eligible veterans. It includes supervised therapy sessions and extra study visits with video recording to track changes over time.
Los Angeles, CaliforniaAges 18 years+ - NCT05811312Recruiting
Spinal cord stimulation and brain changes in chronic pain
This study uses non-invasive brain monitoring to see how spinal cord stimulation may change brain activity in people with chronic nerve pain. It aims to better understand how treatment affects the brain and pain over time.
Cleveland, OhioAges 18 years+ - NCT05787470Recruiting
How hormone levels affect pain signals
This study looks at how hormone treatment and hormone levels may change how the body produces pain signals. It may help researchers better understand pain differences between people with different hormone levels and treatment histories.
Birmingham, AlabamaAges 18–65 - NCT05788016Recruiting
Help planning an opioid taper before knee or hip surgery
This study looks at a plan to safely reduce (taper) opioid pain medicines before total knee or hip replacement surgery. It may help people who are already taking opioids and are preparing for surgery in the next 1 to 2 months.
Birmingham, AlabamaAges 18 years+ - NCT05786417RecruitingPhase 4
Medication comparison for older adults with stable heart pain
This trial tests which heart medications work best for older adults who have stable angina (predictable chest pain) and multiple other long-term health problems. You may be asked to start or adjust medications and attend regular follow-up visits to see which approach controls symptoms and outcomes.
New Haven, ConnecticutAges 65 years+ - NCT05809648Enrolling by invitation
Testing a special scan to better diagnose heart blood-flow problems
This study checks whether a magnet-based heart scan (magnetocardiography) can more accurately find “true ischemia,” which means reduced blood flow to the heart, in people who come to the emergency room with chest pain. It aims to help doctors tell which chest pain is truly from heart blood-flow problems.
Rochester, MinnesotaAges 18 years+ - NCT05805683Recruiting
Calcitonin for nerve pain after spinal cord injury
This study tests whether calcitonin can prevent or lessen nerve pain after a spinal cord injury. It may help reduce how often neuropathic (nerve-type) pain happens and how severe it becomes.
Tanta, Gharbia GovernorateAges 18 years+ - NCT05785884Recruiting
Diet program to help knee osteoarthritis pain
This trial studies whether different diet approaches can reduce knee pain in people with knee osteoarthritis who have certain eating patterns. It may help by changing diet-related factors that can affect inflammation and pain.
Birmingham, AlabamaAges 40–75 - NCT05761860RecruitingEarly Phase 1
Oxytocin to lower opioid misuse risk and pain in older adults
This early-phase study tests whether oxytocin (a hormone-like medication) can reduce how “appealing” opioids feel and also reduce pain. It’s aimed at older adults who have used opioids before but are not currently dealing with chronic pain most days.
Gainesville, FloridaAges 45–85 - NCT05764681Recruiting
Study for long-term pain after surgery
This study is for people who have chronic post-surgical pain and have a planned surgery on a leg or the spine. The goal is to better understand this long-term pain and what may help manage it after surgery.
Wilmington, DelawareAges 5–17 - NCT05748028Recruiting
Testing treatment for pain and nerve symptoms in Parkinson’s
This study looks at pain and “autonomic” (automatic body) symptoms in people with Parkinson’s disease or a related condition called multiple system atrophy. It aims to understand what helps and to learn more about these symptoms in different types of Parkinson-like illnesses.
Telese Terme, BeneventoAges 18 years+ - NCT05746143RecruitingPhase 4
Zolpidem during recovery after lower-back fusion surgery
This trial studies whether taking zolpidem around the time of recovery from lower-back (lumbar) fusion surgery affects outcomes. It may help doctors understand how sleep medicine can (or can’t) support recovery in certain people.
Los Angeles, CaliforniaAges 18–75 - NCT05774717RecruitingPhase 1
Tranexamic acid for bleeding after open nose surgery
This Phase 1 study tests whether tranexamic acid (a medicine that helps reduce bleeding) can lessen bleeding, swelling, and bruising after open rhinoplasty. You may be asked to take it around the time of surgery if you meet safety and lab criteria.
Nashville, TennesseeAges 18 years+ - NCT05772468Enrolling by invitation
Virtual pain care for people getting wound treatment
This trial tests a virtual (VR) pain-care approach during wound care procedures. It may help reduce how painful the treatments feel, especially for people who have had very painful wound care before.
Amsterdam, North HollandAges 18 years+ - NCT05761015RecruitingPhase 4
Test of an NSAID to help osteoarthritis pain when walking
This trial studies whether taking an anti-inflammatory pain medicine (an NSAID) can reduce hip or knee osteoarthritis pain during walking. It may help people who have had walking pain for at least 3 months and don’t already take NSAIDs.
Clermont-FerrandAges 50–70 - NCT05769348Recruiting
PET brain study to test opioid signaling in migraine
This study uses brain scans (PET) to look at how the body’s “opioid” pain system works in people with migraine. It may help researchers understand migraine biology and test approaches that could improve migraine treatment.
