Pain-control injections compared after open kidney surgery
This study compares two types of pain-control injections placed near the back to see which works better after open kidney (nephrectomy) surgery. If you’re having elective open nephrectomy, it may help doctors choose the safest and most effective way to reduce postoperative pain.
İzmitAges 18–85 - NCT05810467Recruiting
Active surveillance study for men at higher risk prostate cancer
This trial studies how well “active surveillance” works for men with prostate cancer who are considered higher risk because of family history or genetics. It aims to safely monitor the cancer and decide the best timing for treatment if needed, while tracking side effects and follow-up success.
Sutton, SurreyAges 18 years+ - NCT05814250Recruiting
Ultrasound in children after a first bladder infection
This trial studies whether doing an ultrasound scan after a child’s first febrile urinary tract infection (UTI) is useful. The goal is to see which children might need further attention based on the scan.
FlorenceAges 2 months–3 years - NCT05817539Recruiting
Early circulation-focused care during kidney dialysis in ICU
This trial looks at whether starting dialysis-related care early, aimed at improving blood flow to tissues, can help people in the ICU who have sudden kidney failure. It may help reduce problems related to poor tissue circulation, but it is very specific about ICU illness and current treatments.
AjaccioAges 18 years+ - NCT05817929Recruiting
Angiopoietin levels and outcomes after heart bypass surgery
This study looks at how a blood protein called angiopoietin relates to recovery and complications after heart surgery that uses a heart-lung machine. If you’re having scheduled heart bypass-type surgery, your team may take blood samples to see whether these levels can help predict outcomes.
AmiensAges 18 years+ - NCT05817903RecruitingPhase 2
Nivolumab with or without axitinib after prior nivolumab
This Phase 2 trial studies whether adding axitinib to nivolumab (or giving nivolumab alone) can better control advanced clear-cell kidney cancer after standard initial treatment with nivolumab plus ipilimumab. It may help by extending response or slowing tumor growth while improving how long treatment works.
BresciaAges 18 years+ - NCT05819229Recruiting
Antibiotics by mouth only for young babies with urine infection
This trial studies whether giving antibiotics by mouth alone is enough to treat a urinary tract infection (UTI) in very young babies. It may help reduce the need for stronger or more invasive antibiotic approaches if you meet the study’s stability and urine-test requirements.
CopenhagenAges 4 weeks–2 months - NCT05822609RecruitingPhase 2
Semaglutide for kidney disease in adults with type 1 diabetes
This Phase 2 study tests semaglutide (a diabetes and weight-related medicine) to see if it can slow or improve diabetic kidney disease in people with type 1 diabetes. You may be able to join if you have type 1 diabetes for at least 5 years and ongoing signs of kidney damage measured in urine tests.
Aurora, ColoradoAges 18 years+ - NCT05824975RecruitingPhase 1/Phase 2
Test drug GI-102 alone or with cancer medicines
This Phase 1/2 study tests whether GI-102 is safe and can help shrink advanced solid tumors. It also looks at GI-102 used with standard cancer treatments like pembrolizumab or trastuzumab deruxtecan (T-DXd).
Scottsdale, ArizonaAges 18 years+ - NCT05825950Recruiting
AI tool for predicting outcomes in bladder cancer
This trial tests an artificial-intelligence (AI) tool that uses your bladder cancer details to help predict outcomes. It may help doctors better choose the next treatment after bladder cancer is found early (non-muscle invasive).
Dallas, TexasAges 18–99 - NCT05826067Recruiting
Testing E. coli from repeat urinary infections
This study collects and studies bacteria (E. coli) found in urine from people with urinary tract infections, including those with repeat infections. It may help improve how doctors understand these infections and choose better future treatments.
BrusselsAges 18 years+ - NCT05830669Recruiting
Remote preconditioning therapy for newly sick sepsis patients
This trial studies whether a “remote preconditioning” treatment given during early sepsis can help protect the kidneys and improve outcomes. It is for adults in the ICU very soon after sepsis begins.
MünsterAges 18 years+ - NCT05832736Recruiting
Robot surgery for one-sided prostate cancer with urethra preserved
This study looks at a robotic prostate operation that aims to remove only the affected side while keeping the urethra (the tube for urination) to help preserve urinary function. It’s for people with low- to intermediate-risk, one-sided prostate cancer and no spread to lymph nodes, bones, or other organs.
Candiolo, TOAges 40 years+ - NCT05833386Recruiting
Silodosin before surgery to help pass an access sheath
This trial looks at whether taking silodosin before flexible ureteroscopy makes it easier to place a special tube (ureteral access sheath) used during kidney stone surgery. If it works, it may make the procedure more feasible and smoother for people having the planned surgery.
CairoAges 18 years+ - NCT05834803Recruiting
Stenting narrowed kidney artery to help high-risk patients
This trial studies whether placing a small stent in a severely narrowed kidney artery can improve outcomes for people with high-risk, artery-hardening kidney blood-flow problems. It focuses on people whose high blood pressure or kidney function has been getting worse despite multiple medications.
Aarhus NAges 18 years+ - NCT05836688Recruiting
Biobehavioral program to help young testicular cancer survivors
This study tests a counseling-style (biobehavioral) program to help reduce upsetting outcomes in young adult testicular cancer survivors. It focuses on people who feel high distress after treatment and aims to improve well-being and coping.
Irvine, CaliforniaAges 18–39 - NCT05836922Recruiting
Checking kidney oxygen after lung transplant to predict kidney injury
This pilot study looks at whether a painless skin sensor can measure kidney oxygen levels after lung transplant surgery. The goal is to predict and possibly prevent postoperative kidney failure by identifying risk early.
MarseilleAges 18 years+ - NCT05838716RecruitingPhase 3
Vitamin D During Hormone Therapy for Prostate Cancer
This trial studies whether taking vitamin D while you are on prostate hormone therapy (ADT) affects your health outcomes. It may help by keeping vitamin D levels in a safe range during treatment.
Newark, DelawareAges 50 years+ - NCT05839314RecruitingPhase 4
Huaier granules for idiopathic membranous nephropathy with PLA2R
This trial studies whether Huaier granules can improve kidney disease activity in people with “idiopathic membranous nephropathy” who test positive for PLA2R antibodies and are still not in remission. Participants will also have been on standard blood-pressure/kidney-protecting treatment (called RASI) for at least 4 weeks.
Beijing, Beijing MunicipalityAges 18–75 - NCT05840484Recruiting
Monitoring study for men on active surveillance
This trial follows men with prostate cancer who choose “active surveillance” instead of immediate treatment. It tests whether careful tracking (including patient reports) can help manage cancer over time and guide decision-making.
Houston, TexasAges 18 years+ - NCT05840575Recruiting
Study of thinking changes in young people during cancer treatment
This study looks at how thinking and memory may change in children and young adults after a new cancer diagnosis, especially around chemotherapy. It may help doctors better understand and track brain-related side effects early.
CopenhagenAges 7–29 - NCT05842239Recruiting
Hyperbaric oxygen therapy for low sperm count infertility
This trial tests whether breathing 100% oxygen in a pressurized chamber (hyperbaric oxygen therapy) can improve fertility in men who have an unexplained low sperm count. It may help by improving sperm health, but you would need multiple sperm tests and to be able to follow the clinic schedule.
ẔerifinAges 21 years+ - NCT05842044RecruitingPhase 2
NSAID pain medicine after robotic kidney-sparing surgery
This Phase 2 study looks at whether taking an anti-inflammatory pain medicine (an NSAID) after robotic partial nephrectomy is safe and helpful. It may reduce pain while checking for stomach, bleeding, and heart-related side effects after kidney-sparing surgery.
Miami, FloridaAges 18–99 - NCT05843851Recruiting
Newborn screening for rare cystinosis and hyperoxaluria
This study offers genetic screening to newborns to look for two rare metabolic conditions. It helps doctors find these conditions earlier, so treatment can start sooner if needed.
