Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07774819RecruitingPhase 1/Phase 2
Radiation therapy for large or treatment-resistant tumors
This trial tests a special type of radiation therapy for tumors that are large (over 4 cm) or have not responded to standard treatments. The goal is to see if this new approach can shrink tumors while limiting side effects.
Shenzhen, GuangdongAges 18–75 - NCT06214611Recruiting
Adaptive radiation therapy for head and neck tumors
This trial tests a special type of radiation therapy that can adjust to changes in your tumor during treatment. It's for people with head or neck tumors who are scheduled for radiation.
Essen, Germany / NRWAges 18 years+ - NCT07726407Recruiting
Surface-guided radiation for head and neck cancer
This trial tests a special camera system (SGRT) to help you stay still during head and neck radiation. It may make treatment more accurate and comfortable by using your own breathing to guide positioning.
Guangzhou, GuangdongAges 18–75 - NCT07686640RecruitingPhase 3
Short course radiation plus chemo with or without immunotherapy for rectal cancer
This trial tests whether adding two immunotherapy drugs (iparomlimab and tuvonralimab) to standard short-course radiation and chemotherapy improves outcomes in people with a common type of locally advanced rectal cancer (pMMR/MSS). It is for those with stage II or III cancer that has at least one high-risk feature and is within 12 cm of the anal verge.
Jinan, ShandongAges 18–75 - NCT07686016Recruiting
Radiation therapy for prostate cancer that has spread to a few spots
This trial studies the use of radiation to the prostate and to all visible spots where cancer has spread, in men who have up to 10 small areas of spread when first diagnosed. The goal is to see if this approach can help control the cancer.
Zamość, Lublin VoivodeshipAges 18 years+ - NCT06595108Recruiting
Targeted therapy and radiation for advanced liver cancer
This trial tests a combination of immunotherapy (atezolizumab), targeted therapy (bevacizumab), and targeted radiation for advanced liver cancer that cannot be surgically removed. The goal is to see if this approach helps control the cancer.
Yongin-siAges 19–80 - NCT07669220RecruitingPhase 2
Short radiation, immunotherapy, and chemo for advanced rectal cancer
This trial compares a new treatment approach—short-course radiation followed by an immunotherapy drug (PD-1 inhibitor) and chemotherapy (FOLFOX)—to the standard long-course chemoradiation for people with a specific type of advanced rectal cancer that is pMMR/MSS. The goal is to see if the shorter treatment works as well or better.
