Tokyo, TokyoAges 18–80 - NCT07215910RecruitingPhase 3
Testing vorasidenib with temozolomide after radiation for advanced brain cancer
This trial tests whether adding the targeted drug vorasidenib to standard chemotherapy (temozolomide) after radiation helps people with a specific type of advanced brain cancer called IDH-mutant astrocytoma. It is for patients who have not had previous treatments like chemotherapy or radiation and whose tumors have certain genetic features.
Duarte, CaliforniaAges 12 years+ - NCT06841159RecruitingPhase 2
Personalized radiation plus immunotherapy and chemo for metastatic colorectal cancer
This trial tests a new combination of ultra-precise radiation therapy, immunotherapy, chemotherapy, and targeted therapy for people with metastatic colorectal cancer that has a normal DNA mismatch repair system. The goal is to see if this personalized approach can better control the cancer and improve outcomes.
ShanghaiAges 18–75 - NCT07216456Recruiting
Vaginal dilator therapy after pelvic radiation
This trial tests a program to help women use vaginal dilators after finishing pelvic radiation for cancers like cervical or anal cancer. It aims to improve vaginal health and quality of life.
Durham, North CarolinaAges 18 years+ - NCT05727410RecruitingPhase 2
Nivolumab and chemotherapy before surgery and radiation for salivary cancer
This Phase 2 study tests giving nivolumab plus docetaxel and cisplatin before surgery and radiation for certain resectable, high-grade salivary gland cancers. It aims to shrink or control the cancer early to improve outcomes after treatment.
SeoulAges 19 years+ - NCT03049072Recruiting
Registry for people treated with ion beam therapy at MedAustron
This trial is a patient registry that collects information from people treated with ion beam therapy at MedAustron. It helps researchers understand treatment patterns and outcomes and may improve care for future patients.
Wiener Neustadt, Lower AustriaAges Any age - NCT07142967Recruiting
MR-Linac radiotherapy for prostate cancer that returned after earlier radiation
This trial tests if a special MRI-guided radiotherapy machine (MR-Linac) can safely treat prostate cancer that has come back after previous radiation therapy. It may help men who have limited options and want to avoid more invasive treatments.
New York, New YorkAges 18 years+ - NCT06949254Recruiting
Study of radiation and hormone therapy for high-risk prostate cancer
This study looks at combining stereotactic body radiation therapy (a precise type of radiation) with hormone therapy for men with high-risk prostate cancer that hasn't spread. The goal is to see how well this treatment works with fewer side effects.
