DNA test to help kidney transplant patients switch to a single anti-rejection drug
This trial uses DNA testing and gene expression profiling to see if kidney transplant recipients can safely switch to a belatacept-only immunosuppression regimen. The goal is to simplify your anti-rejection drugs while keeping your kidney healthy.

MRI vs. TURBT for muscle-invasive bladder cancer
This study compares two ways to check if bladder cancer has grown into the muscle layer: an MRI scan (mpMRI) versus a standard surgery called TURBT (where a small tool removes a sample of the tumor). The goal is to see if the MRI can be as accurate as the surgery, so future patients might avoid an extra procedure.
Orange, CaliforniaAges 18 years+ - NCT06331546Recruiting
Study of gut oxalate absorption in calcium oxalate kidney stone patients
This study looks at how your gut absorbs oxalate, a natural substance in many foods that can lead to kidney stones. By eating special diets and pausing certain supplements, researchers can measure your oxalate absorption. This may help find better ways to prevent kidney stones.
Birmingham, AlabamaAges 18–80 - NCT06325046Recruiting

This trial tests a type of radiation that adapts to your body's changes during treatment. It is for men with low- to intermediate-risk prostate cancer that hasn't spread.
Albert Lea, MinnesotaAges 18 years+ - NCT06026592Recruiting
Detecting kidney DNA in transplant patients' blood
This study looks for small pieces of kidney DNA in the blood of kidney transplant patients. It aims to improve monitoring of transplant health.
Paris, Île-de-France RegionAges 18 years+ - NCT06312644Recruiting
Study of Ultomiris safety during pregnancy
This study looks at the safety of the medication Ultomiris when taken during pregnancy or breastfeeding. If you are pregnant and currently taking Ultomiris for an approved condition, this research will help gather information on how it affects you and your baby.

Study of IG3018 for high uric acid with or without kidney disease
This trial tests a new medicine, IG3018, to lower high uric acid levels in people with or without chronic kidney disease. It aims to find the right dose and see if it's safe.
Botany, New South WalesAges 18–75 - NCT06308978RecruitingPhase 1
Study of FT819 for B-cell autoimmune diseases
This trial tests a new cell therapy, FT819, for people with certain autoimmune diseases like lupus, vasculitis, myositis, or scleroderma that haven't improved with at least two previous treatments. The goal is to see if it can help control the disease.
Beverly Hills, CaliforniaAges 12–70 - NCT06312722Recruiting
Optilume BPH catheter system for enlarged prostate symptoms
This trial tests a device called Optilume BPH Catheter System for men with enlarged prostate that causes bothersome urinary symptoms. It aims to see how safe and effective it is in real-world use, offering a possible treatment for blocked urine flow without surgery.
Little Rock, ArkansasAges 50 years+ - NCT06305390RecruitingPhase 2
PSMA PET/MRI for prostate cancer diagnosis
This trial tests a new, all-in-one PET/MRI scan to see if it can better find aggressive prostate cancer in men who need a biopsy. It may help avoid unnecessary biopsies and give a clearer picture of your condition.
Milan, MilanoAges 18 years+ - NCT06306612Recruiting
Surgery plus hormone therapy for advanced prostate cancer
This trial tests whether removing the prostate (surgery) plus standard hormone therapy and chemotherapy can help men whose prostate cancer has spread to many places in the body. It is for men who have not yet had treatment for their cancer.
Shanghai, Shanghai MunicipalityAges 18–85 - NCT06300788Recruiting
Pyrophosphate study in children with kidney disease
This study looks at a natural chemical in the body called pyrophosphate (PPi) in children with chronic kidney disease. It aims to understand how kidney problems affect this chemical, which is important for bone health. The study needs kids with different kidney stages, including those on dialysis, with a transplant, or even healthy kids having surgery for comparison.
Nice, Alpes-MaritimesAges birth–18 years - NCT06303622Recruiting
Comparing two MRI-guided biopsy methods for prostate cancer
This trial compares two ways to guide a prostate biopsy using MRI images, to see which better detects clinically significant prostate cancer in men with suspicious MRI findings.
Hong KongAges 18 years+ - NCT06295770RecruitingPhase 2
Obinutuzumab for fibrillary glomerulonephritis
This trial tests whether obinutuzumab, a targeted therapy that quiets certain immune cells, can reduce kidney damage in people with fibrillary glomerulonephritis. If you have this rare kidney condition and significant protein in your urine, this study may offer a new treatment option.
Rochester, MinnesotaAges 18 years+ - NCT06302595Recruiting
MRI-guided prostate biopsy for cancer diagnosis
This trial uses MRI to guide a biopsy of the prostate, aiming to better detect cancer in men with abnormal PSA levels, a lump, or a suspicious MRI finding.
Boston, MassachusettsAges 30 years+ - NCT06315595Recruiting
Better MRI scans for blood vessels and blood flow
This study tests a new MRI technique to get clearer images of blood vessels and blood flow using a contrast dye, and also explores MRI methods that don't need contrast at all. The goal is to improve how doctors see and assess blood flow issues without added risk.
Scottsdale, ArizonaAges 18 years+ - NCT06299683Recruiting
Pain type and bladder pain syndrome treatment study
This study is testing if the type of pain you feel can help predict which treatments work best for interstitial cystitis (a condition that causes bladder pain and pressure). It may help match you with more effective care.
Franklin, TennesseeAges 18 years+ - NCT06306963Recruiting
Stomach blood vessel condition and digestion symptoms study
This study looks at people with a stomach condition called gastric antral vascular ectasia (GAVE) to understand how it affects digestion and causes symptoms. Researchers want to learn if stomach muscle function problems are common in this condition.
Rochester, MinnesotaAges 19 years+ - NCT06310759Recruiting
