Heart procedure to close an atrial clot risk pouch in kidney failure
This trial tests a heart procedure that closes a part of the heart called the left atrial appendage to help prevent stroke in people with an irregular heartbeat (atrial fibrillation) and very advanced kidney disease. It’s mainly for patients who can take the needed blood-thinner medicines and who do not already have a clot in that pouch.
Lübeck, Schleswig-HolsteinAges 18 years+ - NCT05109208Recruiting
Ultrasound check for erection recovery after prostate surgery
This study looks at whether ultrasound imaging can help understand and improve erectile function after prostate removal surgery that aims to protect the nerves. If you’re interested in keeping or improving erections, your ultrasound results may be used to guide follow-up care.
Rochester, MinnesotaAges 40 years+ - NCT04954690Recruiting
Exercise program after kidney transplant for older adults
This trial tests a structured, coached exercise program for people who recently received a living-donor kidney and are coming from dialysis. It may help improve strength and daily function after transplant, especially if starting fitness is difficult.
San Francisco, CaliforniaAges 50 years+ - NCT04748770Recruiting
Kidney Transplant Access for Obese Dialysis Patients
This study looks at whether obese patients who are starting dialysis can safely receive kidney transplants. Researchers want to understand how weight affects transplant success and access to this life-changing treatment.
AmiensAges 18 years+ - NCT06766838Recruiting
Comparing circumcision methods for young boys
This study compares different circumcision techniques in boys under age 5. It will help doctors understand which method works best.
SohagAges Up to 5 years - NCT04702022Recruiting
Extra PET scan to check for silent kidney transplant rejection
This study tests whether an additional PET scan can help detect and guide treatment for “subclinical” (silent) rejection in people with kidney transplants. It may help doctors spot problems earlier and manage them more appropriately.
Liège, LiègeAges 18 years+ - NCT04819217Recruiting
Probiotics and a toxin binder to slow chronic kidney disease
This trial studies an oral product (a “uremic toxin” absorber) plus probiotics to help slow the progression of chronic kidney disease. It may help by lowering harmful gut-related substances that can build up when kidney function is reduced.
TaipeiAges 20 years+ - NCT05024344Recruiting
Nerve block to reduce pain after kidney stone surgery
This trial tests whether an “ESP block” (a targeted local anesthetic injection near nerves) works better than standard care to control pain after percutaneous kidney stone removal. If it helps with pain, it could reduce the need for stronger pain medicines after surgery.
Knoxville, TennesseeAges 18 years+ - NCT04838899Recruiting
Radiation for limited, progressing prostate cancer on abiraterone
This study tests whether a very focused type of radiation (SABR) can control a small number of prostate cancer spots that are starting to grow while you’re already on abiraterone. It may help by treating only the areas that are progressing, while other areas remain controlled.
Toronto, OntarioAges 18 years+ - NCT05608694Recruiting
MRI screening for men at high risk of prostate cancer
This trial is testing whether MRI scans can help screen for signs of prostate cancer in men who have not been diagnosed yet but are at higher risk. It may help find concerning changes earlier so doctors can follow up sooner.
Chicago, IllinoisAges 18 years+ - NCT05086003RecruitingPhase 2
Kidney transplant with stem cell treatment to build immune tolerance
This Phase 2 study tests a combined treatment—kidney transplant plus stem cell–based immune therapy—to help the body accept the new kidney with less immune attack. You may be able to take part if you have a matching sibling donor and meet key safety and health requirements.
Petah TikvaAges 18–65 - NCT05015231Recruiting
MRI study after fistula closure in kidney transplant patients
This trial uses special MRI scans to see how blood flow in the transplanted kidney changes after your fistula is surgically closed. It may help doctors better understand what healthy recovery looks like after the procedure.
ZurichAges 18 years+ - NCT04180397RecruitingPhase 4
Removing extra fluid in critically ill ICU patients with overload
This trial studies a medicine strategy to remove extra fluid from the body in ICU patients who have fluid overload. It aims to see whether controlled fluid removal is safer and better for recovery than usual care.
SydneyAges 18 years+ - NCT03764852Recruiting
Tests outpatient surgery for pelvic organ prolapse with double mesh
This study checks whether an outpatient (same-day) approach to a specific prolapse repair surgery is safe and practical, using a double-mesh method with or without robotic help. You may be offered the surgery under guidance of the study team if you meet the health and medical safety criteria.
ClamartAges 40–80 - NCT05732077Recruiting
Stent decisions for kidney artery narrowing in hard-to-control blood pressure
This trial studies whether using a pressure-based test called fractional flow reserve (FFR) helps doctors choose the right kidney artery stent for people with narrowing of kidney arteries and high blood pressure. It may help improve blood pressure control while avoiding unnecessary procedures.
Beijing, Beijing MunicipalityAges 18 years+ - NCT03851640RecruitingPhase 3
Study drug for advanced prostate cancer that kept spreading despite standard treatments
This Phase 3 study tests HC-1119 soft capsules in men with metastatic castration-resistant prostate cancer—cancer that keeps progressing even when testosterone is blocked. It aims to see whether the drug works better than expected and is safe, especially after prior treatments like abiraterone and/or docetaxel.
ShanghaiAges 18 years+ - NCT05613010Recruiting
Tech tools to help young transplant patients take meds correctly
This study tests technology (like text reminders and an electronic pill box) to help adolescents and young adults who received a kidney or liver transplant take their medicines every day. It may help protect the transplant by improving medication adherence.
Baltimore, MarylandAges 13–25 - NCT05390892RecruitingPhase 4
Preventing kidney and heart damage in type 2 diabetes
This study tests whether diabetes medicines can help prevent worsening heart and kidney problems in people with type 2 diabetes. You’ll be assigned by chance to one of these medicine types, and your other care will be adjusted for safety.
Huntsville, AlabamaAges 40–80 - NCT04046042Recruiting
Virtual reality during dialysis, comparing first vs last
This trial tests whether using virtual reality during hemodialysis affects how patients feel or do during treatment. It compares using virtual reality at the beginning of the dialysis session versus the end.
Manises, ValenciaAges 18 years+ - NCT05635175Recruiting
Hip abductor training for women with stress urine leakage
This trial tests whether specific hip muscle exercises can reduce stress urinary incontinence (urine leaks with activities like coughing or exercise). If it works, it could improve bladder control using perineal (pelvic-area) rehabilitation plus hip-focused training.
CaenAges 18 years+ - NCT03305861Recruiting
GreenLight or ThuLEP surgery for a very enlarged prostate
This trial compares two types of laser surgery for people with a very enlarged prostate causing bothersome urinary symptoms after medicine didn’t help. It aims to find which approach works better and is safer for improving urine flow and quality of life.
Al Mansurah, Dakahlia GovernorateAges 40–80 - NCT03615872Recruiting
Checking comfort and satisfaction with a prolapse pessary
This study looks at how satisfied people feel when using a vaginal support pessary for genital prolapse. It may help find pessary options that are more comfortable and easier to live with.
CaenAges 18 years+ - NCT03547973RecruitingPhase 2
Study of sacituzumab govitecan for advanced or non-removable bladder cancer
This trial tests sacituzumab govitecan, an anti-cancer drug, for people with urothelial (bladder/urinary tract) cancer that has spread or can’t be removed with surgery. It’s designed for tumors that have been treated already in specific ways, to see if the medicine can shrink or control the cancer.
Tucson, ArizonaAges 18 years+ - NCT03001921Recruiting
Practice add-on for people on hemodialysis
This trial is for people with end-stage kidney disease who are already receiving hemodialysis. It tests a “wise practice” program or approach during dialysis to see if it can help patients in some meaningful way.
