This Phase 3 trial tests whether the immunotherapy drug pembrolizumab (Keytruda) can help prevent bladder cancer from returning after surgery. About 739 patients with muscle-invasive or locally advanced urothelial cancer are randomly assigned to receive pembrolizumab or just be o…

This phase 2 trial is testing a combination of two immunotherapy drugs, nivolumab and ipilimumab, in 798 people with over 50 types of rare cancers. The goal is to see if these drugs can shrink tumors by helping the immune system attack cancer cells. Participants receive the drugs…

This phase III trial tests whether adding cabozantinib to avelumab (an immunotherapy) helps keep metastatic urothelial cancer from growing after initial chemotherapy. About 654 patients will receive either the combination or avelumab alone as maintenance therapy. The goal is to s…

This study tests whether adding the chemotherapy drug eribulin to the immunotherapy atezolizumab works better than atezolizumab alone for people with advanced or spreading bladder cancer who cannot take standard cisplatin chemo. About 72 adults with recurrent or metastatic urothe…

This early-stage trial tests a new drug called LY4101174 in people with advanced solid tumors, including bladder, breast, and lung cancers. The drug is an antibody-drug conjugate designed to target and kill cancer cells. The study will check if the drug is safe, tolerable, and ef…

This early-phase trial is testing a combination of two drugs—erdafitinib and enfortumab vedotin—in 24 people with advanced bladder cancer that has spread and has specific FGFR2/3 gene changes. Erdafitinib blocks a faulty protein that helps cancer grow, while enfortumab vedotin de…

This early-phase study tests a combination of two or three drugs (cabozantinib, nivolumab, and sometimes ipilimumab) in people with advanced genitourinary cancers that have spread. The main goals are to find the safest doses and understand side effects. About 152 adults with vari…

This early-phase trial tests a combination of three drugs—bortezomib, gemcitabine, and doxorubicin—in people with advanced urothelial cancer or other solid tumors that cannot be removed by surgery. The main goal is to find the highest safe dose of the two chemotherapy drugs when …

This study compares two treatments for a rare type of urinary tract cancer. One group gets chemotherapy before surgery, the other has surgery alone. The goal is to see if chemo helps shrink the tumor and improve long-term outcomes. About 120 adults with high-risk, non-spread canc…

This study looks at whether people with advanced bladder cancer can stop taking immunotherapy drugs (like pembrolizumab or nivolumab) after about a year instead of continuing indefinitely. The goal is to see if stopping early leads to similar survival rates while reducing side ef…

This early-phase trial tests whether combining two drugs—avelumab (an immunotherapy) and AVB-S6-500 (a targeted therapy)—is safe and can help people with advanced bladder cancer that has worsened after chemotherapy. Nineteen adults with inoperable or metastatic urothelial carcino…

This study tests whether adding tocilizumab (a drug used for arthritis) to standard immunotherapy can reduce severe side effects in people with advanced melanoma, lung cancer, or bladder cancer. About 35 participants will receive all three drugs. The goal is to see if the combina…

This early-phase trial is testing whether giving two immunotherapy drugs (durvalumab and tremelimumab) before surgery can help patients with aggressive bladder cancer who cannot take standard chemotherapy. The study involves 54 participants and primarily looks at safety and how t…

This phase 2 trial is testing whether adding propranolol, a common blood pressure drug, to standard immunotherapy can help control advanced bladder cancer. The study enrolled 6 adults with urothelial carcinoma that has spread or cannot be removed by surgery. Researchers are prima…

This early-phase trial tests whether adding the immunotherapy drug pembrolizumab to standard platinum-based chemotherapy can help people with rare, aggressive small cell or neuroendocrine cancers of the bladder or prostate. The study includes 15 participants whose cancer has spre…

This study tests whether new software for ultrasound machines can better detect and measure kidney stones compared to standard methods. Researchers will scan 370 adults with known calcium-based kidney stones and compare the results to CT scans and surgical findings. The goal is t…

This study compares two laser methods for breaking up kidney and ureteral stones during surgery. One method uses standard laser pulses, the other uses a newer 'Moses 2.0' pulse mode. Researchers want to see if the newer mode reduces surgery time and improves stone clearance. Abou…

This study compares two drugs—methocarbamol and oxybutynin—to see which works better for pain and discomfort caused by a ureteral stent placed after kidney stone surgery. About 126 adults aged 18 to 80 who have the surgery will take one of the study drugs along with standard pain…

This study examines stored tumor samples from 15 people with kidney or bladder cancer who initially responded to immune checkpoint therapy but later developed new tumors. Researchers will compare the genetic and tissue features of the original and new tumors to understand how the…

This small phase II trial is studying whether specific gene mutations (ARID1A and KDM6A) and a protein called CXCL13 can predict how well patients with advanced bladder cancer respond to the immunotherapy drug nivolumab. Six participants with metastatic urothelial cancer whose tu…

This study was designed to measure how often urine flows backward from the bladder into the ureter after placing a special stent (RELIEF) in people with kidney stones. Researchers planned to use bladder X-rays to check for reflux and track any symptoms. However, the study was wit…

This study follows 1,600 people with small kidney stones (4 mm or less) to see how often they pass without help. Participants report symptoms, give blood, and get a follow-up CT scan. The goal is to find out if pain, stone size, or location can predict natural passage within 4 to…

This study creates a large registry of people with and without urothelial cancer (bladder, ureter, or renal pelvis cancer) to learn how genes and lifestyle affect risk. Participants provide a saliva sample and fill out questionnaires. The goal is to improve prevention, diagnosis,…
