Brain stimulation study to change brain connections
This study tests whether a non-surgical brain stimulation technique (placing a gentle electrical current through the scalp) can change how different parts of the brain communicate.

Winnipeg, ManitobaAges 18 years+ - NCT05961202RecruitingPhase 2/Phase 3
Hydroxychloroquine for inflammatory heart muscle weakness
This trial tests hydroxychloroquine to see if it improves symptoms and heart function in people with inflammatory cardiomyopathy (inflammation of the heart muscle). It’s mainly for adults with a specific type of past myocarditis and ongoing heart failure despite standard treatments.
Wuhan, HubeiAges 18–80 - NCT05962190Recruiting
Short-term extra fat intake to study liver metabolism
This study tests what happens to the liver and fat metabolism when you eat extra fat for a short time. It may help researchers understand how diet affects liver function and metabolism in otherwise stable adults.
OxfordAges 18–65 - NCT05964712Recruiting
Therapies for acromegaly and effects on body movement
This study looks at how treatments for acromegaly affect how you function and move, especially in your hands, feet, and overall body structure. You may be asked to do assessments to understand changes over time and whether certain groups respond differently.
MilanAges 18–90 - NCT05964387Recruiting
Silver fluoride treatment and local numbing for tooth cavities
This study tests whether applying silver diamine fluoride (a cavity-stopping liquid) changes how well local numbing works during dental treatment for certain tooth defects. It may help determine the safest and most comfortable way to treat weak, cavity-prone molars in children.
Ann Arbor, MichiganAges 6–11 - NCT05965076Recruiting
Test glycine powder and a special brush for oral care
This trial studies whether using glycine powder and an angled implant brush helps keep dental implants healthy in people following the Columbus Bridge ProtocolTM. It may help by improving daily oral hygiene around implants and reducing implant problems.
TorinoAges Any age - NCT05966727Recruiting
Cholestyramine to lower stored pollutants in obese women
This study tests whether cholestyramine can lower blood levels of certain stored environmental pollutants (“POPs”) in women preparing for weight-loss surgery. If it works, it may help reduce pollutant levels that can build up in the body over time.
Nice, Alpes-MritimesAges 18–45 - NCT05967741Recruiting
Dietary erythritol trial for blood clot and inflammation health
This study tests whether eating erythritol (a sugar substitute) affects how your platelets (blood-clot cells) react and how inflamed your blood vessels are. You may benefit by helping researchers understand whether erythritol has effects on heart-and-blood-vessel risk.
Davis, CaliforniaAges 18–70 - NCT05967910Recruiting
How stress affects immunotherapy for esophageal cancer
This study looks at whether chronic stress changes how well immunotherapy (ICI therapy) works in people with esophageal cancer. It may help doctors understand who benefits most from treatment and how stress could affect outcomes.
Changsha, HunanAges 18–75 - NCT05968885RecruitingPhase 4
Compare Botox and combination medicines for overactive bladder
This study tests whether Botox injections work better than a combination of medicines (anti-muscarinics plus a beta-3 medicine) for people whose overactive bladder symptoms did not improve with one medicine alone. It may help by improving bladder control and reducing urgent, hard-to-hold urine leaks or frequent urination.
TaipeiAges 20–90 - NCT05968664Recruiting
Test whether new spinal cord stimulation settings improve chronic pain
This trial studies whether changing the “stimulation pattern” of spinal cord stimulation can reduce long-lasting pain and improve daily function. You might be a good candidate if you have chronic trunk or leg pain and have already tried multiple pain treatments without enough relief.
Houston, TexasAges 22 years+ - NCT05968677Recruiting
Amino acids and flavonoids to reduce chemotherapy side effects
This trial tests whether a specific nutrition supplement (amino acids and flavonoids) can lessen chemotherapy side effects, support nutrition, and improve quality of life in people with non-metastatic breast cancer. It focuses on women who are receiving certain chemotherapy medicines and can eat by mouth and attend regular visits.
PaviaAges 50–70 - NCT05969665Recruiting
Wearable monitoring to improve heart risk factors
This study looks at whether using a wearable to track your glucose level and physical activity can improve heart-related risk factors in people with coronary heart disease. You may be asked to use a smartphone and follow a monitoring plan, along with any standard cardiac rehab routines.
BaselAges 18 years+ - NCT05971225Recruiting
Testing remote heart monitoring to improve heart outcomes
This study checks whether starting remote wireless heart monitoring for people with heart failure helps improve important heart outcomes. It may help your care team catch warning signs earlier by receiving your heart data from home.
Suwon, Kyonggi DoAges 20 years+ - NCT05973045Recruiting
Warm or cool fluid during hysteroscopy: comfort and safety
This study looks at whether the temperature of the fluid used during hysteroscopy affects image quality, risk of low blood sodium, and pain after the procedure. It may help find a safer, more comfortable way to do hysteroscopy for certain uterine growths.
