Gene-guided hormone therapy before prostate cancer surgery
This trial tests whether giving a combination of hormone treatments before surgery can improve outcomes for men with prostate cancer that has spread locally or to a few bone spots. It uses genetic testing to match participants with the most effective treatment.
Xiamen, FujianAges 18 years+ - NCT07150715RecruitingPhase 2
Radioactive drug plus precise radiation for recurrent prostate cancer
This trial tests a powerful radioactive drug (either alpha or beta) combined with precise radiation to treat prostate cancer that has come back in a few spots outside the prostate. It may help men whose cancer is still hormone-sensitive and has not spread widely.
Los Angeles, CaliforniaAges 18 years+ - NCT06406179Recruiting
Blood test for donor DNA in kidney transplant care
This trial is testing whether a simple blood test that looks for donor DNA can help doctors take better care of kidney transplant patients. It may help detect early signs of rejection and guide treatment decisions.
ParisAges 18 years+ - NCT07142967Recruiting
MR-Linac radiotherapy for prostate cancer that returned after earlier radiation
This trial tests if a special MRI-guided radiotherapy machine (MR-Linac) can safely treat prostate cancer that has come back after previous radiation therapy. It may help men who have limited options and want to avoid more invasive treatments.
New York, New YorkAges 18 years+ - NCT06408298RecruitingEarly Phase 1
Hydroxychloroquine before prostate cancer surgery
This trial tests whether a drug called hydroxychloroquine (HCQ) can help before prostate cancer surgery. It is for people with localized prostate cancer who are planning to have their prostate removed.
Lebanon, New HampshireAges 18 years+ - NCT06632613RecruitingPhase 2
Trial of ENN0403 to prevent kidney injury after heart surgery
This study tests a new drug (ENN0403) given during heart surgery to see if it prevents acute kidney injury—a sudden drop in kidney function. The trial is for people who are already at higher risk due to their specific heart surgery and other health factors.
ShanghaiAges 18–85 - NCT06975995Recruiting
Postbiotics for elderly dialysis patients
This trial tests whether postbiotics (helpful substances made by good bacteria) can reduce complications in elderly patients on hemodialysis. If you are 65 or older and have been on dialysis for at least 6 months, this study may help improve your treatment.
Beijing, Beijing MunicipalityAges 65 years+ - NCT07570771Recruiting
Dialysis duration effects on bladder function in transplant candidates
This study examines how long you've been on dialysis and how much urine you still produce might affect your bladder's ability to hold and stretch after a kidney transplant. Understanding this helps doctors predict how well your bladder will work after you receive a new kidney.
Karachi, SindhAges 18–65 - NCT06422845Recruiting
Drug-coated balloon for dialysis fistula narrowing
This trial tests a special balloon that releases medication to help keep your dialysis fistula (the blood vessel used for treatment) open longer if it has narrowed. It may be a good option if you have a blockage in the vein side of your fistula that causes problems during dialysis.
Hefei, AnhuiAges 18–80 - NCT07598227Recruiting
Moxibustion Treatment for Nighttime Urination
This trial tests whether moxibustion—a traditional Chinese medicine technique using heat—can reduce how many times you need to urinate at night. If you wake 2+ times nightly to urinate, this study explores whether moxibustion might help you sleep better.
Hualien CityAges 40 years+ - NCT07532382Recruiting
Personalized Stories to Help Young Kidney Transplant Recipients
This study uses personalized storytelling to help children aged 5–12 who have received a kidney transplant. Researchers believe that hearing stories from other transplant recipients might help children understand their condition better and cope with their new life after transplant.
Paris, Île-de-France RegionAges 5–12 - NCT07134595Recruiting
Comparing two peritoneal dialysis schedules in children with kidney failure
This trial tests a modified version of daily peritoneal dialysis (M-CAPD) versus the standard version (C-CAPD) for children in low-resource settings who have end-stage kidney disease. It aims to see if the modified schedule works better for clearing waste and fluid.
Manila, ErmitaAges 2–18 - NCT05042453Recruiting
Long-term follow-up of Splentis for uterine prolapse repair
This trial follows women who have symptoms of uterine prolapse and are getting surgery with a device called Splentis. The study looks at whether Splentis works over the long term and whether it has any important side effects.
ChemnitzAges 18 years+ - NCT07721636Recruiting
Vexus ultrasound to set dry weight in dialysis
This trial uses a special ultrasound scan (VEXUS) to help doctors find the right 'dry weight' for people on hemodialysis. The goal is to remove just the right amount of fluid without strain.
AlexandriaAges 25–65 - NCT06759831Recruiting
Clinical outcomes of living and deceased donor kidney transplants
This study looks at how well kidney transplants work from both living and deceased donors. It may help doctors better understand long-term outcomes for people who get a new kidney.
Bologna, BOAges 18 years+ - NCT05768464RecruitingPhase 2
Surgery aftercare for non-clear kidney cancer at high risk
This Phase 2 trial studies an after-surgery treatment for people with non-clear types of kidney cancer who are at high risk of coming back. It aims to lower the chance of recurrence by giving extra therapy after your tumor is completely removed.
Nanjing, JiangsuAges 18–75 - NCT04792320Recruiting
Probiotics and fiber for kidney disease with leg artery blockage
This study tests whether an oral absorbent plus probiotics can improve gut health and circulation in people who have chronic kidney disease and symptomatic peripheral artery disease (PAD). It will also track changes in blood markers and how well blood vessels function.
TaipeiAges 20 years+ - NCT04788914Recruiting
Test saliva or blood markers to track kidney and leg disease treatment
This study looks at a gene marker (“lncRNA,” a natural molecule in the body) to see how well an oral absorbent, with or without probiotics, is helping people with chronic kidney disease (CKD) who also have blocked leg arteries. It may help doctors better measure treatment impact and tailor care.
Taipei, TaiwanAges 20 years+ - NCT07700251Recruiting
Comparing two surgeries for kidney stones in children
This study compares two types of surgery for removing kidney stones in children. It aims to see which method works better and is safer for stones up to 2 cm.
Qina, South ValleyAges 1–18 - NCT05708508RecruitingPhase 3
Immune-guided vs universal medicine to prevent CMV after kidney transplant
This study compares two strategies to prevent a viral infection called CMV after kidney transplant. It tests whether an “immune-guided” approach (using your immune test results) can prevent CMV as well as or better than giving preventive antiviral medicine to everyone.
RouenAges 18–75 - NCT06155084RecruitingPhase 1/Phase 2
HP518 for advanced prostate cancer that has spread
This trial tests an oral drug called HP518 for men with a specific genetic change in their prostate cancer that has spread and stopped responding to standard hormone therapy and chemotherapy. The goal is to see if HP518 can control the cancer.
Hefei, AnhuiAges 18 years+ - NCT07181096Recruiting
Frailty in kidney transplant patients and kidney function
This study looks at frailty (weakness and tiredness) in kidney transplant patients and how it relates to how well the transplanted kidney is working. It may help find ways to improve long-term transplant health.
AlexandriaAges 18 years+ - NCT06707792Recruiting
6-minute stepper test reliability in kidney transplant patients
This study checks if a 6-minute stepper test is a valid and reliable way to measure exercise ability in people who have had a kidney transplant. It helps doctors understand your fitness without needing complex equipment.
AnkaraAges 18–65 - NCT04704505RecruitingPhase 2
Testosterone-like treatment plus radium for bone-spread prostate cancer
This trial studies whether adding a testosterone-related therapy (BAT) to radium-223 can better control prostate cancer that has spread mainly to the bones. It may help shrink tumors in the bone and slow PSA rises, which are a common marker of prostate cancer activity.
