ClichyAges 18 years+ - NCT06355050Recruiting
Short, intense radiation for prostate cancer
This trial tests a very short course of daily radiation that adapts to your body's changes. It aims to be just as effective as standard treatment but more convenient.
JenaAges 18–120 - NCT06349317RecruitingPhase 2
Radiation, immunotherapy, and targeted therapy before surgery for liver cancer with portal vein tumor thrombus
This trial tests whether combining radiation (IMRT) with two drugs—camrelizumab (an immunotherapy) and apatinib (a targeted therapy)—before surgery can help people with liver cancer that has spread to the main blood vessel of the liver (portal vein). The goal is to shrink the tumor and improve surgical outcomes.
Fuzhou, FujianAges 18–75 - NCT06327477RecruitingPhase 1/Phase 2
A new type of radiation for newly diagnosed retroperitoneal sarcoma
This trial tests a new way of giving radiation called proton spatially fractionated radiotherapy (P-SFRT) combined with standard radiation for people with a type of sarcoma in the back of the belly. The goal is to see if this combination can treat the tumor more effectively.
Chicago, IllinoisAges 18 years+ - NCT06323239RecruitingPhase 2
Radiation plus chemo and immunotherapy for advanced nasopharyngeal cancer
This trial tests a combination of two types of radiation therapy (standard SBRT and low-dose radiation) along with chemotherapy and an immunotherapy drug (PD-1 antibody) for people whose nasopharyngeal cancer has come back or spread. The goal is to see if this combination can better control the cancer.
Guangzhou, GuangdongAges 18–75 - NCT06323460RecruitingPhase 2
Less Radiation for HPV Throat Cancer Guided by a Blood Test
This study tests a way to use less radiation for HPV-related throat cancer. Doctors will adjust your treatment based on a simple blood test that tracks cancer DNA, so you may get only the treatment you need.
Columbus, OhioAges 18 years+ - NCT06328686RecruitingEarly Phase 1
Arginine and whole brain radiation for brain metastases
This trial tests whether taking arginine (an amino acid) during whole brain radiation therapy can help people with brain metastases from any type of cancer. It looks at how the treatment affects the body and may improve outcomes.
