Balancing sex hormones to improve metabolism and fertility in Klinefelter
This study tests whether adjusting sex-hormone levels can improve body metabolism and reproductive hormone balance in people with Klinefelter syndrome. Depending on the design, you may be looking at fertility preservation and/or metabolic health.
LausanneAges 16–65 - NCT05588128Recruiting
Scan study for prostate cancer after PSA comes back
This study follows people with prostate cancer whose PSA blood test has risen again after standard treatment. It uses an approved PET scan tracer to look for cancer spread, which may help doctors understand how the disease is progressing.
Bethesda, MarylandAges 18 years+ - NCT05588063Recruiting
Device-based nerve stimulation for relapse-preventing kidney disease in kids
This trial tests whether a small non-surgical device can help keep children with steroid-sensitive nephrotic syndrome in remission. If it works, it could lower the chance of relapse (kidney flare-ups) and help maintain kidney health.
New Hyde Park, New YorkAges 3–17 - NCT05588700Recruiting
Exercise program to reduce long-term cancer fatigue
This trial studies whether a structured physical activity program can reduce ongoing (long-term) fatigue in men with metastatic testicular cancer. It likely helps by improving fitness and energy during and after first-line chemotherapy.
AngersAges 18 years+ - NCT05589207Recruiting
Model to predict outcomes in kidney cancer with IVC wall invasion
This study uses information from scans and surgery findings to build a prediction model for people with kidney cancer that has grown into a major vein (the IVC). It aims to help doctors better estimate outcomes and guide care after surgery.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05590624Recruiting
Mediterranean diet study for men on prostate cancer active surveillance
This trial studies how different controlled versions of a Mediterranean-style diet may affect prostate cancer-related metabolism in men choosing active surveillance. It may help participants understand whether diet changes influence markers linked to prostate cancer activity, while keeping them on a monitored care plan.
Cleveland, OhioAges 18 years+ - NCT05597852Recruiting
Rectal gel spacer to help repeat prostate radiation
This trial studies whether placing a soft gel spacer near the rectum can make “salvage” prostate radiation safer and more tolerable when prostate cancer comes back locally. It may help reduce side effects by creating extra space between the rectum and the radiation area.
Toronto, OntarioAges 18 years+ - NCT05598645Recruiting
Thulium vs holmium laser for kidney stone procedures
This trial compares two types of lasers used during a procedure to remove kidney stones through the urinary tract. It may help you understand which laser works better for clearing stones while keeping the procedure safe.
Thunder Bay, OntarioAges 18 years+ - NCT05600400Recruiting
Test two vs five MRI-guided treatments for prostate cancer
This trial is comparing two different MRI-guided radiation treatment plans to see which one better improves sexual quality of life in prostate cancer. It may help people decide between shorter or more treatment-session radiation approaches.
Toronto, OntarioAges 18 years+ - NCT05602246Recruiting
Compare two surgeries for vaginal bulging
This trial tests whether one type of vaginal wall repair works better than another surgery for women with vaginal bulging (anterior prolapse). It may help find the safest and most effective operation to reduce symptoms.
Hradec KrálovéAges 50 years+ - NCT05612022Recruiting
Sound recording during hemodialysis fistula decisions
This study records and analyzes sounds from people getting hemodialysis through an access in the arm (an AV fistula or graft). It aims to see whether sound patterns can help assess or guide the best vascular access approach for dialysis.
Bergamo, BGAges 18–90 - NCT05613023RecruitingPhase 3
Short-course prostate and pelvic SBRT using 5 treatment sessions
This study compares two schedules of highly focused radiation (SBRT): 5 sessions to the prostate only, versus 5 sessions to the prostate and nearby pelvic lymph nodes. It aims to see which approach controls high-risk localized prostate cancer better while you also take hormone therapy.
CorkAges 18 years+ - NCT05616481Recruiting
Compare two types of bladder support surgery for stress leaks
This trial compares two laparoscopic (camera-assisted) surgery techniques for stopping stress urinary incontinence—leaks that happen when you cough, sneeze, or exercise. It may help determine which approach works better and with fewer problems for the right patients.
Cairo, Cairo GovernorateAges 18 years+ - NCT05616650RecruitingPhase 2
Targeted radiation for one prostate tumor spot
This Phase 2 study tests a focused radiation approach using stereotactic body radiation therapy (SBRT) for people with one prostate tumor visible on imaging. It aims to treat a single tumor area while limiting treatment to the rest of the prostate.
Bethesda, MarylandAges 18–120 - NCT05618886Recruiting
Pelvic floor exercises for urinary leakage in women
This study tests whether pelvic floor muscle training (exercises) can improve urinary incontinence (urine leakage) in Nepalese women. If you qualify, you may be asked to learn and do the exercises as part of a research program and share feedback during follow-up.
Dhulikhel, Kavrepalanchok District- 3Ages 18–45 - NCT05620784RecruitingPhase 3
Loop water pills during surgery to go home sooner after HoLEP
This trial tests whether giving a “loop diuretic” water pill during surgery can help people after HoLEP go home the same day more often. It’s mainly looking to improve discharge timing while keeping you safe.
Chicago, IllinoisAges 18–89 - NCT05621837Recruiting
Biomarker study to guide treatment for several advanced cancers
This study measures how strongly your immune system is being suppressed and uses that information to help personalize cancer treatment. It mainly looks at people with certain advanced cancers and needs tumor tissue and follow-up to check possible immune-related markers.
MilanAges 18–90 - NCT05627219Recruiting
Training men to share prostate cancer genetics info
This study tests a program that trains men (especially African American men) to help others understand prostate cancer genetic counseling and testing. It may improve access to this information by using peer support and patient navigation.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05627726Recruiting
PelviSense device for stress urinary leakage
This trial studies whether a wearable biofeedback device called PelviSense can reduce stress urinary incontinence (leakage that happens with activities like coughing or exercise) and whether it’s worth the cost. If you qualify, you may be asked to use the device and complete study visits and tests to measure symptom changes.
Hong KongAges 35–65 - NCT05628987Recruiting
Gut bacteria study in men with sperm production problems
This trial looks at whether gut bacteria (microbiome) and lifestyle factors are linked to poor sperm production or sperm quality. You may be asked for stool, urine, and blood samples and to complete questionnaires about diet and habits to help researchers understand possible connections.
Guangzhou, GuangdongAges 18–45 - NCT05629494RecruitingPhase 4
Ibuprofen vs PSA blood test for prostate evaluation
This trial studies whether an anti-inflammatory medicine (ibuprofen) changes prostate-specific antigen (PSA) blood test results to help decide on next diagnostic steps like MRI or biopsy. It may help people with an elevated PSA understand whether follow-up testing is more or less likely to be needed.
Chicago, IllinoisAges 18–80 - NCT05635669Recruiting
Acupuncture for mild to moderate stress urine leaks
This trial studies whether an “optimized” acupuncture treatment can reduce urine leakage caused by stress, like coughing or laughing. It is mainly for adults with mild to moderate stress urinary incontinence who are medically able to receive acupuncture.
ShanghaiAges 40–75 - NCT05638269Recruiting
Study of gut bacteria in people with serious long-term illness
This study looks at the types of gut bacteria in people living in certain parts of China who have serious long-term (chronic) illnesses. The goal is to better understand how gut bacteria differ and may help doctors in the future tailor care.
