Check PD-1 plus enfortumab after kidney-urine-duct surgery
This Phase 2 study tests giving pembrolizumab (an immune therapy) and enfortumab vedotin (an antibody-drug medicine) before and after surgery to remove high-risk upper urinary tract cancer. The goal is to lower the chance the cancer comes back.
Los Angeles, CaliforniaAges 18 years+ - NCT06523868Recruiting
Multi-cancer early detection test for military veterans
This trial is testing a blood test that looks for early signs of multiple types of cancer. It is designed for current or former military members who are at least 45 years old and have used VA healthcare. If the test finds something, you would need to be willing to travel to Boston for follow-up.
Boston, MassachusettsAges 45 years+ - NCT06830798RecruitingPhase 3
Ravulizumab to prevent delayed graft function after kidney transplant
This study tests an investigational medicine (ravulizumab) given through a vein to see if it can prevent delayed graft function—meaning the new kidney takes longer to start working—after a high-risk kidney transplant. It is for adults on dialysis who are getting a kidney from a donor whose heart stopped or who is considered high-risk.
Phoenix, ArizonaAges 18 years+ - NCT07208240RecruitingPhase 1/Phase 2
PSMA-targeted radiation before prostate removal for advanced cancer
This trial tests giving a radioactive drug (PSMA-targeted) before surgery for prostate cancer that has spread locally but not to other parts of the body. The goal is to see if it helps lower the risk of the cancer coming back.
Petah TikvaAges 18 years+ - NCT06047977RecruitingPhase 1
Immune cell therapy for high-risk solid tumors in children and young adults
This trial uses a patient's own tumor-fighting immune cells (TILs) to treat high-risk solid tumors outside the brain in children and young adults. It has two parts: first, a tumor sample is collected during surgery, and then the immune cells are grown in a lab and given back to the patient to attack the cancer.
St. Petersburg, FloridaAges 1–21 - NCT07264790RecruitingPhase 1
Minoxidil for Better Blood Flow in Breast Reconstruction
This trial tests whether applying minoxidil (a hair growth medication) to breast tissue during surgery can improve blood flow to the reconstructed breast. It is for women who are having both breasts removed to prevent cancer and have reconstruction on the same day.
Durham, North CarolinaAges 18 years+ - NCT07270887Recruiting
Can gentle arm cuffs protect your heart and brain over time?
This trial tests if using a blood pressure cuff on your arm in short cycles can help prevent future heart attacks, strokes, and other problems in people at very high risk. You may qualify if you've already had a major heart or blood vessel event.
ShenyangAges 40 years+ - NCT05796739Recruiting
Stress testing once or only when needed for high calcium risk
This study compares two approaches to stress testing in people who feel fine but have high coronary artery calcium on a scan. It may help determine whether testing routinely is better than doing it only if symptoms or concerns arise.
SeoulAges 19 years+ - NCT07230639RecruitingPhase 2
Shorter radiation with chemo and immunotherapy for high-risk colon cancer
This trial tests a shorter course of radiation combined with chemotherapy and an immunotherapy drug (PD-1 inhibitor) for people with a specific type of high-risk colon cancer that has not spread. The goal is to see if this approach can shrink the tumor before surgery and improve outcomes.
Guangzhou, GuangdongAges 18–75 - NCT07053436RecruitingPhase 2
