Oklahoma City, OklahomaAges 18–90 - NCT04022616Recruiting
Study immune cells in breast cancer patients
This study looks at how certain immune cells behave in people with breast cancer. It may help researchers understand the disease and how the immune system affects it.
Columbus, OhioAges 18 years+ - NCT03921944Recruiting
CT and nerve tests after shoulder replacement for arthritis
This study checks how well the rotator cuff (the shoulder’s key tendons/muscles) is working after a total shoulder replacement done for arthritis. It uses CT scans and nerve testing to see what affects shoulder structure and function, which may help improve future care.
Hershey, PennsylvaniaAges 45 years+ - NCT03916978RecruitingPhase 2/Phase 3
PRP treatment to help restore ovarian function in menopause
This trial tests whether injecting your own PRP (platelet-rich plasma) into the ovaries can improve ovarian function in some menopausal women. It may help those whose menopause seems less advanced, but not everyone will be eligible based on health and test results.
AthensAges 45–55 - NCT03914664Enrolling by invitation
Brain and sensation study in adults with Tourette syndrome
This study looks at brain activity and how sensory experiences feel in adults with Tourette syndrome. It compares you to carefully matched adults without neurologic or psychiatric conditions to understand what is different in the brain.
Nashville, TennesseeAges 18 years+ - NCT04005469RecruitingPhase 1/Phase 2
Treprostinil to protect kidneys during transplant injury
This early-phase study tests whether treprostinil (Remodulin®) can reduce injury to a transplanted kidney right after surgery. If it works and is safe, it may help improve outcomes for people receiving a deceased-donor kidney transplant.
Providence, Rhode IslandAges 18–75 - NCT03869138Recruiting
Improving physical function after stroke using alternative therapies
This study tests alternative therapies to help improve physical abilities like walking, balance, and arm/leg function after a stroke. It may help if you can follow instructions and safely participate in supervised movement exercises.
Chicago, IllinoisAges 18–90 - NCT03752034Recruiting
Muscle fragments after rotator cuff surgery to improve shoulder function
This study looks at whether using “muscle fiber fragments” during/after rotator cuff repair can help your shoulder work better. It targets people with a small tear in one shoulder who can follow the post-surgery follow-up plan.
Winston-Salem, North CarolinaAges 40–80 - NCT03800017Recruiting
Muscle strength and exercise function in lung scarring
