This trial compares two standard treatment options—radiation or surgery—for people with high-risk prostate cancer that has not spread. The goal is to see which approach works better for long-term cancer control and side effects.
AlkmaarAges 50–75 - NCT05936606Recruiting
Personalized blood thinner choice after stent placement
This trial tests whether tailoring anti-platelet (blood clot prevention) treatment can better protect people at higher risk of heart or blood-vessel problems after a drug-eluting stent. It may help prevent future clots and complications, especially in patients with certain high-risk health conditions or complex stent/scar tissue features.
SeoulAges 19–80 - NCT05943379RecruitingPhase 2
RC48 antibody plus gemcitabine for high-risk bladder cancer
This Phase 2 study tests RC48, an antibody-based drug, combined with gemcitabine to treat high-risk, non-muscle invasive bladder cancer that has not responded well to BCG or cannot receive BCG. It may help shrink tumors and reduce the chance of the cancer coming back.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05945121Recruiting
Exercise and coaching program to protect heart in stem cell transplant
This trial tests a pre-transplant exercise and training program to improve heart “reserve,” or how well your heart handles stress, in people at higher heart risk. If you qualify, you may be asked to use a heart-rate tracking app during the program before your stem cell transplant.
Ann Arbor, MichiganAges 18 years+ - NCT05946213RecruitingPhase 3
Shorter radiation treatment for high-risk prostate cancer
This trial tests whether a shorter course of radiation works as well as the usual longer course for people with high-risk prostate cancer. The goal is to keep cancer control while possibly reducing treatment time and inconvenience.
Birmingham, AlabamaAges 18 years+ - NCT05962541RecruitingPhase 4
Using bladder scans to plan repeat surgery for bladder cancer
This trial checks whether a bladder scan and score (VI-RADS from MRI) can help doctors choose the right way to do a second look surgery for non-muscle-invasive bladder cancer. The goal is to reduce the chance of needing extra (“secondary”) resections while still catching important disease early.
Rome, LazioAges 18 years+ - NCT05968157Recruiting
Breast MRI check for women at high risk
This study compares a newer breast cancer risk approach with standard guidelines, and then uses a special MRI to look for cancer early. If the MRI looks concerning, doctors will confirm the finding with a biopsy.
Worcester, MassachusettsAges 40 years+ - NCT05976412Recruiting
Radiation to lymph nodes after surgery for higher-risk breast cancer
This trial looks at whether adding targeted radiation to lymph nodes after breast surgery can lower the chance of breast cancer coming back in people with higher-risk, node-negative disease. If you qualify, you may get a planned radiation approach designed for prevention, not treatment of spread.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05993442Recruiting
Skin-to-skin care to reduce infections in early babies
This study is testing if giving more skin-to-skin care (called Kangaroo Care) to very early-born babies in the NICU can reduce serious infections and the spread of resistant bacteria. It is for babies born before 32 weeks in certain hospitals.
AthensAges Up to 7 months - NCT05994170Recruiting
Lower radiation dose to tumor area for early nasopharyngeal cancer
This trial studies whether lowering the radiation dose to a smaller area around the tumor is safe and effective for people with newly diagnosed nasopharyngeal cancer that has not spread. It may reduce side effects while still curing the cancer.
Zhongshan, GuangdongAges 18–70 - NCT06013423RecruitingPhase 2
Cord blood transplant with chemo and radiation for high-risk blood cancers
This trial tests a cord blood transplant after a reduced-intensity chemotherapy and radiation regimen for patients with high-risk blood cancers like leukemia, lymphoma, or MDS. The goal is to see if this approach can help destroy cancer cells and restore healthy blood cells.
Seattle, WashingtonAges 6 months–65 years - NCT06013618RecruitingPhase 2
Naxitamab for high-risk or relapsed neuroblastoma in children
This trial tests a targeted antibody called naxitamab (hu3F8) for children with high-risk neuroblastoma that has come back or is hard to treat. It aims to see if this therapy can help shrink or control the cancer with an acceptable safety profile.
Guangzhou, GuangdongAges 1 year+ - NCT06016569Recruiting
Breath test for early lung cancer in high-risk smokers
This study tests a new breath test to find early signs of lung cancer in people at high risk. It looks for cancer biomarkers in the air you breathe out. If you are a heavy smoker between 55 and 74, this trial may help detect lung cancer earlier.
BrnoAges 55–74 - NCT06028113RecruitingPhase 2
A weight gain prevention program for high-risk babies in primary care
This study tests a program to help prevent unhealthy weight gain in babies at higher risk for obesity. Families will get extra support during regular check-ups at a pediatric clinic.
