Recruiting studies
- NCT05615610Recruiting
Electrical stimulation therapy for brain and arm recovery after stroke

Collect tumor samples to guide early breast cancer recurrence care
This Phase 2 study tests a “precision” approach using tumor sample testing to help predict, prevent, and treat early metastatic recurrence in triple-negative or hormone-receptor–low, HER2-negative breast cancer. If you qualify, you’ll be asked to provide tumor tissue before (or in place of) standard chemotherapy, so researchers can learn which tumor features matter most.
Salt Lake City, UtahAges 18 years+ - NCT05329662RecruitingPhase 2
Stem cell treatment for sexual function problems in perimenopausal women
This Phase 2 study tests an injected stem cell treatment made from body fat to improve sexual function in women who are in the perimenopause stage (not yet fully through menopause). You may qualify if your hormone and symptom levels suggest decline and you meet general health and infection-safety checks.
HanoiAges 40–65 - NCT04665739RecruitingPhase 2
Lutetium Lu-177 for lung carcinoid tumors with somatostatin receptors
This trial tests lutetium Lu 177 dotatate, a targeted radiation treatment, for advanced lung neuroendocrine (carcinoid) tumors that have a specific marker called somatostatin receptors. It may help shrink tumors by delivering radiation directly to cancer cells that “light up” on a special scan.
Birmingham, AlabamaAges 18 years+ - NCT04648124Recruiting
MRI brain scan study in hereditary retinal vision loss
This study uses functional MRI (a type of brain scan) to understand how the brain processes vision in people with inherited retinal disorders. You might be included if you are an adult with hereditary retinal degeneration and are planning certain vision-related treatments soon.
Paris, PARISAges 18 years+ - NCT05821140Recruiting
Assessing jaw and bite function in children with oral health issues

Clermont-FerrandAges 3–17 - NCT04276181Recruiting
Nerve and tendon transfer surgery for hand function after spinal cord injury
This trial studies a specialized surgery that reroutes nerves and tendons to help restore hand and grip function after a spinal cord injury. It may help some people regain more useful hand movement if their arm muscle strength and nerve signals are strong enough.
MölndalAges 15–55 - NCT02846064Recruiting
Ovarian tissue graft to restore ovarian function
This study looks at using your own frozen ovarian tissue that was saved earlier, then grafting it back to help restart normal ovarian function. It may be an option for people with premature ovarian failure who have been treated for their original cancer/illness.
BesançonAges 18–43 - NCT06232473RecruitingPhase 4
Education and duloxetine for multisystem functional somatic disorder
This trial tests whether a combination of patient education and the medication duloxetine can help people with a condition that causes multiple unexplained physical symptoms (functional somatic disorder). It aims to see if using both treatments together works better than either alone.
AarhusAges 18–60 - NCT06357897Recruiting
New PEG formula for children with functional constipation
This trial tests a new, better-tasting liquid formula (PEG-based) for children with functional constipation. It aims to see if it works as well as or better than current treatments and if children like the taste more.
BangkokAges 6 months–18 years - NCT06396247RecruitingPhase 2/Phase 3
Daily leg exercises to improve walking
This study tests a simple daily leg-strengthening routine to see if it helps people who have trouble walking short distances. You'll do easy resistance exercises at home, which might make it easier to walk and move around.
Hershey, PennsylvaniaAges 65 years+ - NCT06398977Recruiting
Dapagliflozin to protect kidney function in dialysis patients
This trial tests whether a diabetes drug called dapagliflozin can help people on peritoneal dialysis keep their remaining kidney function longer. It is for patients who started dialysis recently and still make urine.
Chengdu, SichuanAges 18–75 - NCT06823700Recruiting
Study of SQ-Kyrin device for leaky mitral valve from heart failure
This trial tests a new device (SQ-Kyrin) to fix a leaky mitral valve without open-heart surgery. It is for people with heart failure whose valve leak causes symptoms, and who are not good candidates for traditional surgery.
Valladolid, ValladolidAges 18 years+ - NCT06221722Recruiting
Brain scan study for treating constipation
This trial uses brain scans to see if doctors can predict how well constipation treatments will work. It is for adults with functional constipation, but only if they have no other digestive problems or medical implants.
Yinchuan, NingxiaAges 18–45 - NCT07419633Recruiting
Study on supplements to improve strength and thinking in older adults
This trial tests if two supplements, HMB and 2-HOBA, taken alone or together, can help improve muscle strength and mental function in healthy adults over 65. The goal is to see if these supplements can improve overall quality of life.
Montreal, QuebecAges 65 years+ - NCT07637383Recruiting
Exercise Program to Improve Daily Function in Hospital Care
This study tests whether a structured exercise program can help patients in intermediate care hospitals regain their ability to do everyday activities like walking and self-care. The program is designed for people recovering from illness or injury.
Manresa, BarcelonaAges 65 years+ - NCT07497100Recruiting
Arm function and daily life in hemiplegic cerebral palsy

Diepenbeek, FlandersAges 65–85 - NCT07548424Recruiting
Testing a Peptide Cream on Healthy Skin
This study tests whether a cream containing peptides (small protein fragments) can improve how well your facial skin barrier works. The cream will be tested on one side of your face, compared to the other side, to see if it strengthens and protects your skin.
SplitAges 18–50 - NCT07329933Recruiting
Steroids and sedatives for faster recovery after gallbladder surgery

BanhāAges 18–65 - NCT07081139Recruiting
Visual screening study for children with special needs
This study uses a video-based eye-tracking system to test how well children with special needs and typical preschoolers can see. It aims to find a friendly way to screen vision without asking children to read letters.
TaipeiAges birth–70 years - NCT06724679Recruiting
Virtual reality for chronic back pain treatment

Common questions
- Are there clinical trials for functionality?
- Yes. Clin2 currently lists 2,550 recruiting functionality studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a functionality trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a functionality trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
