Fisetin for better walking and strength in breast cancer survivors
This study tests whether fisetin (a natural compound) can improve physical function, like walking ability, in breast cancer survivors who feel frail. It may help strengthen muscles and improve daily activity after treatment.
Alhambra, CaliforniaAges Any age - NCT05634031Recruiting
Study of heart vessel dysfunction seen on heart imaging
This study looks at coronary microvascular dysfunction (small blood vessel problems in the heart) using heart imaging. It may help researchers understand causes of chest tightness with activity and shortness of breath when the main heart arteries are not blocked.
New York, New YorkAges 18 years+ - NCT05624125Recruiting
Beetroot juice study for circulation problems in leg arteries
This trial tests whether drinking beetroot juice can improve how well people with peripheral artery disease (PAD) can function and walk. It’s looking at circulation-related measurements in the legs and how you do on walking tests.
Chicago, IllinoisAges 50 years+ - NCT05611775Recruiting
Spinal surgery patients tracked for daily activity after surgery
This trial follows adults who are getting a multi-level spinal deformity correction surgery with special pelvic attachment. It looks at how well you return to real-life function and activity after surgery using follow-up visits at Mayo Clinic.
Rochester, MinnesotaAges 18 years+ - NCT05593055RecruitingPhase 4
Test a heart and blood-pressure therapy in people with hypertension
This study looks at how mineralocorticoid-related hormone signaling affects small heart blood vessels and how efficiently the heart works in people with high blood pressure. It may help doctors understand which treatments could improve heart function in hypertension.
Boston, MassachusettsAges 18–75 - NCT05626816Recruiting
Genital nerve stimulation to improve bowel control after spinal injury
This trial studies whether stimulating nerves near the genitals (a gentle electrical stimulation approach) can improve bowel function in people with spinal cord injury. It may help bowel control when bowel dysfunction is caused by nerve injury.
Cleveland, OhioAges 18 years+ - NCT05574244Recruiting
Partial vs complete prostate surgery to preserve ejaculation
This trial compares two surgical approaches for men with benign prostate enlargement (BPH): one that aims to preserve ejaculation and one that removes more tissue. It looks at how well you recover urinary function and sexual outcomes after surgery.
Aix-en-ProvenceAges 40 years+ - NCT05576090Recruiting
Study tests sleep skills in UCLA students with insomnia symptoms
This study looks at whether sleep techniques can improve sleep problems. It’s designed for UCLA students living on campus who report meaningful insomnia symptoms, and it may help you learn practical ways to sleep better.
Los Angeles, CaliforniaAges 18–22 - NCT05586360RecruitingPhase 2
Testing how a statin may change immune markers in prostate cancer
This Phase 2 study tests whether taking simvastatin can change “immune regulation” markers in men with intermediate- to high-risk localized prostate cancer. It also looks at whether this could help lower the risk of cancer coming back after planned prostate surgery.
Atlanta, GeorgiaAges 18 years+ - NCT05588284Enrolling by invitation
Check whether a special treatment protects vein valves after clot
This study enrolls people with an acute blood clot in the thigh or pelvis veins to see how well a procedure called PCDT (using a Zelante device) preserves the function of vein valves. It may help reduce complications like ongoing vein problems after a clot.
