- NCT05120076RecruitingPhase 3
Dexamethasone during surgery to reduce hip surgery pain and nausea
This trial tests whether a single steroid medicine called dexamethasone given around the time of surgery can reduce pain and nausea after a periacetabular osteotomy. It may help you feel more comfortable in the first days after surgery, depending on your medical history.
ZurichAges 18–99 - NCT05122403Recruiting
MRI-guided brain procedure for stubborn nerve pain
This trial tests a brain treatment guided by MRI to treat chronic nerve (neuropathic) pain that hasn’t improved with many prior treatments. It may help reduce pain intensity when standard pain medicines and procedures have not worked.
Beijing, Beijing MunicipalityAges 18–75 - NCT05127265Recruiting
AI and sensors to monitor patients in the ICU
This study uses AI and sensor data to better monitor people while they are in an intensive care unit (ICU). It may help teams notice changes sooner and improve care for ICU patients.
Gainesville, FloridaAges 18 years+ - NCT05127616Recruiting
Trial for chronic pelvic pain: CBT vs education/support
This study tests whether structured talking therapy (CBT) or education/support helps reduce chronic pelvic pain problems in adults. It compares two approaches over time and uses symptom diaries and follow-up check-ins to see which works better.
Los Angeles, CaliforniaAges 18–70 - NCT05131178Recruiting
Study for pain control after C-section
This trial looks at how to reduce pain after a C-section (cesarean delivery). You may be able to join if you’re having a scheduled or urgent C-section and can use the planned pain-control method.
Aurora, ColoradoAges 18–50 - NCT05141591Recruiting
Anxiety before ENT surgery and opioid use after surgery
This trial looks at whether people’s anxiety before ear, nose, and throat (ENT) surgery affects how much pain medicine (opioids) they need after surgery. It may help doctors better plan pain control based on anxiety level and possibly gender-related patterns.
Vienna, State of ViennaAges 18 years+ - NCT05142267Recruiting
Study stress and opioid-risk factors in chronic low back pain
This study looks at how stress and the body’s natural opioid/cannabinoid systems may relate to risk of opioid misuse. It tests people with long-lasting low back pain to see what biological or psychological factors might increase or lower that risk.
Nashville, TennesseeAges 18 years+ - NCT05146778Recruiting
Opioid-free anesthesia to reduce long-term post-mastectomy pain
This study tests whether a pain-control approach without opioids (strong pain medicines) can lower persistent pain after mastectomy. It may help people avoid long-term pain and opioid side effects.
SeoulAges 19–80 - NCT05147948Recruiting
Online therapy for PTSD plus chronic pain symptoms
This trial tests an iACT program (a structured, online skills-based therapy) for people who have both PTSD symptoms and chronic pain that affects daily life. It may help you learn ways to better handle distress and improve everyday functioning.
LundAges 18–65 - NCT05150795RecruitingEarly Phase 1
Testing pregabalin before surgery versus fentanyl during surgery
This trial compares two medicines used around the time of surgery—pregabalin given by mouth before surgery versus fentanyl given during surgery—to see which better controls pain after the operation. You might join if you’re a generally healthy surgical patient and aren’t using certain related medicines.
CairoAges 21–45 - NCT05152264Recruiting
TENS device study for endometriosis-related chronic pain
This study tests whether a skin-applied electrical nerve pain-relief device (TENS) can help with long-lasting pain from endometriosis. It mainly looks at people who have confirmed endometriosis and are on stable hormone treatment.
GothenburgAges 18–100 - NCT05162794Recruiting
Laparoscopic surgery for endometriosis: does it help or harm?
This study compares whether a minimally invasive surgery to remove endometriosis tissue helps relieve pelvic pain, or causes unwanted effects. You may be asked to rate your pain and follow the study plan around the time of surgery.
Horsens, Central JutlandAges 18–50 - NCT05172739RecruitingPhase 4
Opioid-free anesthesia during lung surgery for early lung cancer
This study tests whether an opioid-free pain/anesthesia plan during elective lung surgery can reduce surgical “stress” on the body and affect the immune system. You may be eligible if you have early-stage non-small cell lung cancer and are scheduled for a specific type of surgery (VATS lobectomy).
Heraklion, CreteAges 18–80 - NCT05174247Recruiting
Using FFRct to guide tests for stable chest pain
This study checks whether adding FFRct analysis (a special computer-based estimate of blood flow from a CT scan) improves the diagnostic pathway for people with stable chest pain. It may help doctors decide what to do next by clarifying how much a narrowed heart artery is truly limiting blood flow.
Rotterdam, South HollandAges 18 years+ - NCT05176392Recruiting
Stimulation treatment plus therapy for post-injury headaches
This study tests whether a noninvasive brain stimulation treatment combined with therapy can reduce long-lasting headaches after a mild brain injury. You might be a good candidate if your headaches started after the injury and have continued for months.
San Diego, CaliforniaAges 18–65 - NCT05179928Recruiting
Numbing injections for less pain after belly surgery
This trial compares two different numbing injection techniques to help control pain after surgery above the belly button. It may help people who qualify have better or longer-lasting pain relief with fewer side effects.
Damanhūr, El-BeheiraAges 21–60 - NCT05188183Recruiting
Remote brain stimulation plus hand training for phantom limb pain
This trial tests whether remote brain stimulation (tDCS) combined with sensory (hand/limb) training can reduce phantom limb pain. It also uses computer prediction (“machine learning”) to estimate who is most likely to benefit.
Cambridge, MassachusettsAges 18 years+ - NCT05193227RecruitingPhase 2
Slow-release lidocaine patch for pain after pelvic surgery
This Phase 2 study tests a slow-release form of lidocaine to reduce pain after surgery that uses a pelvic incision. If you’re having a qualifying pelvic operation, the study may help see whether this medication improves postoperative pain control.
Vancouver, British ColumbiaAges 19 years+ - NCT05196503RecruitingPhase 3
PRF gel in spine surgery to reduce nerve pain after herniation
This Phase 3 study tests whether applying a healing material called platelet-rich fibrin (PRF) around the nerve during disc herniation surgery can reduce leftover nerve pain afterward. If you qualify, your team will compare pain intensity between standard care and PRF during the operation.
Strasbourg, Bas-RhinAges 18 years+ - NCT05204472Recruiting
Deep brain stimulation for ongoing nerve pain after stroke or facial nerve issues
This trial studies whether a special brain device (deep brain stimulation, or DBS) can reduce long-lasting nerve pain. It focuses on one-sided pain after certain brain injuries or specific facial nerve pain causes, especially when medicines haven’t helped enough.
BernAges 18–75 - NCT05214547Recruiting
Focal vibration therapy for frozen shoulder pain and motion
This trial studies whether a vibration device applied to the shoulder can reduce pain and improve range of motion in people with frozen shoulder (also called adhesive capsulitis). If you fit the specific shoulder and symptom pattern, it may be an option to consider alongside standard care.
BitlisAges 18 years+ - NCT05216328RecruitingPhase 4
Prevent constipation in people with advanced cancer on opioids
This study tests whether starting a bowel-prevention approach can help stop constipation caused by opioid pain medicines in people with advanced (metastatic) cancer. You may be able to join if you are about to start long-acting or skin opioid pain treatment.

Ramat Gan, CenterAges 18–52 - NCT05230446Recruiting
Testing full stent treatment for heart artery blockages
This study looks at how well doctors can treat multiple blocked heart arteries using a specific drug-eluting stent, aiming to fully open them. It may help patients whose blockage pattern fits the study, but it does not include certain high-risk or special cases.
