This study checks how well a new prostate MRI scan (using a flexible coil and multiple MRI types) can correctly identify prostate cancer and help with treatment planning. You may be able to help doctors improve prostate imaging before you have surgery.
Houston, TexasAges 18 years+ - NCT05058170Enrolling by invitation
MRI study of scar changes after kidney transplant
This study uses MRI (a special scan) to look for kidney-transplant scarring and related changes. It may help doctors better understand what is happening in the transplanted kidney and guide future care.
New York, New YorkAges 18 years+ - NCT04981509RecruitingPhase 2
Check if 3 medicines help advanced kidney cancer
This Phase 2 trial tests whether combining bevacizumab, erlotinib, and atezolizumab can shrink or control advanced kidney cancer. It’s aimed at people with certain kidney-cancer subtypes (including HLRCC-related cases or papillary kidney cancer) and who have not had many prior targeted or immune treatments.
La Jolla, CaliforniaAges 12 years+ - NCT04948658Recruiting
Freezing ovarian tissue to protect future fertility
This study looks at storing ovarian (ovary) tissue by freezing it for people at higher risk of losing fertility. It may help preserve options for having biological children later, especially for certain genetic conditions, cancer-related risks, or planned gonad removal.
Bethesda, MarylandAges 2–35 - NCT04969315RecruitingPhase 1/Phase 2
Study of two new drugs for advanced kidney, prostate, lung, or mesothelioma cancer
This study tests two new study drugs (TT-4 and TT-10) alone and together in people with certain advanced cancers that have not responded to standard treatments. The goal is to see if these drugs are safe and effective in shrinking tumors or slowing the cancer's growth.
Los Angeles, CaliforniaAges 18 years+ - NCT04981119Recruiting
Test apheresis for CAR T manufacturing in HLA-A2 solid tumors
This trial studies how a process called apheresis is used to make CAR T cells for people with certain solid tumors. It is designed for tumors that have lost a specific immune marker (HLA-A*02), which may affect how well CAR T therapies work.
Gilbert, ArizonaAges 18 years+ - NCT04977453RecruitingPhase 1/Phase 2
Study drug GI-101 alone or with immune or blood-pressure meds
This early-phase study tests GI-101 in people with advanced solid cancers. It may be given alone or combined with pembrolizumab or lenvatinib to see how safe it is and whether it can shrink tumors.
New York, New YorkAges 18 years+ - NCT05000294RecruitingPhase 1/Phase 2
Atezolizumab plus tivozanib for hard-to-treat “cold” cancers
This early-stage study tests whether combining atezolizumab and tivozanib can shrink advanced, hard-to-treat cancers that do not strongly activate the immune system (“immunologically cold”). It is for people whose cancer has already been treated or has no good standard options.
Gainesville, FloridaAges 18–99 - NCT04984226RecruitingPhase 2
Sodium bicarbonate for kidney disease energy and acidity
This trial studies whether taking sodium bicarbonate changes “energy” in cells and improves metabolic acidosis (an acid build-up) in people with moderate-to-severe chronic kidney disease. You may be able to join if your kidney function and blood bicarbonate levels fit their targets and you meet safety rules.
Sacramento, CaliforniaAges 21–85 - NCT04947254RecruitingPhase 2
Add niraparib to hormone therapy after prostate radiation
This Phase 2 trial tests whether adding niraparib to standard hormone therapy (androgen ablation) after radiation works better for men with high-risk, localized or locally advanced prostate cancer. It may help control the cancer for longer, while also collecting extra tissue and blood to study why the treatment works or doesn’t.
Houston, TexasAges 18 years+ - NCT04932902Enrolling by invitation
Treatment and outcomes study for priapism
This study looks at how doctors manage priapism (a painful, unwanted erection that lasts a long time) and how different approaches affect outcomes. It may help improve care for people with priapism by tracking what works best and what to expect.
Catania, CTAges 18 years+ - NCT04934540Recruiting
Bladder tumor surgery approach registry study
This study is for adults who have a bladder tumor and are having a standard kind of surgery through the urethra. Researchers will collect information about this “en bloc resection” approach to better understand outcomes and care for people with bladder tumors.
Hong KongAges 18 years+ - NCT04987086Recruiting
68Ga PSMA PET-CT for kidney cancer spread
This study checks whether a special PET-CT scan using 68Ga PSMA can better find where renal cell carcinoma has spread. It may help doctors plan the right next steps by confirming suspected metastases on CT.
Lanzhou, GansuAges 18–90 - NCT04993859Recruiting
Testing how chemotherapy affects kids’ urinary markers
This study looks at urinary (bladder and urine) measurements in children who previously had cancer and were treated with certain chemotherapy drugs. It may help researchers understand how past chemotherapy can affect bladder function and related health markers over time.
Aurora, ColoradoAges 5–13 - NCT04945642Recruiting
Radiation combination therapy for intermediate to high-risk prostate cancer
This trial studies a combination of two radiation types—high-dose-rate brachytherapy and stereotactic body radiotherapy—to treat certain intermediate- to high-risk prostate cancers. It may help by aiming radiation closely at the prostate while also targeting the cancer from outside the body.
Los Angeles, CaliforniaAges 18 years+ - NCT04939935RecruitingPhase 3
Metformin to slow kidney decline in adults with polycystic kidneys
This Phase 3 study tests whether taking metformin can slow the decline of kidney function in adults with autosomal dominant polycystic kidney disease (ADPKD). You may be eligible if you have ADPKD and signs that your kidneys are starting to decline faster than expected.
Gosford, New South WalesAges 18–70 - NCT04932148Recruiting
Dialysis support study for people starting hemodialysis
