Denver, ColoradoAges 18 years+ - NCT06120387Recruiting
Radiation after kidney-sparing surgery for high-risk ureteral cancer
This trial tests whether adding radiation therapy after surgery that removes only part of the ureter or the entire kidney and ureter helps prevent cancer from coming back in patients who have high-risk features like aggressive cell type or deep tumor invasion.
BeijingAges 18 years+ - NCT06111898Recruiting
Understanding movement in infants at risk
This study looks at how the brain and body work together to control movement in infants who are at high risk for developmental issues. It may help find early signs of motor problems.
GenevaAges 8 months–1 year - NCT03868722RecruitingPhase 2/Phase 3
Acalabrutinib plus venetoclax for high-risk CLL with infection risk
This study tests whether acalabrutinib plus venetoclax can control newly diagnosed chronic lymphocytic leukemia (CLL) in people who are at higher risk of infections or who likely need treatment soon. It aims to see if this combination can improve disease control while keeping patients safe.
CopenhagenAges 18 years+ - NCT06170710RecruitingPhase 2
Immunotherapy after chemoradiation for high-risk head and neck cancer
This trial tests if adding immunotherapy after standard chemoradiation helps prevent cancer from returning in people with high-risk head and neck cancer. It is for those who have completed surgery and have certain high-risk features.
Beijing, Beijing MunicipalityAges 18–70 - NCT06092957RecruitingPhase 3
Reduced radiation after chemo-immunotherapy for high-risk nasopharyngeal cancer
This trial tests whether a lower dose of radiation, with or without additional chemo-immunotherapy, works as well as the standard full-dose chemoradiation for people with advanced nasopharyngeal cancer who had a complete response after initial chemo-immunotherapy.
