Jacksonville, FloridaAges 65–99 - NCT06310564Recruiting
SBRT for limited metastatic colorectal cancer
This trial tests whether focused radiation (SBRT) can treat 1 to 3 metastases in people with colorectal cancer that has spread but is still low or intermediate risk. It may be an option if you are starting first or second line systemic therapy and your primary tumor is under control.
Negrar, VeronaAges 18 years+ - NCT06313190RecruitingPhase 2
SBRT plus immunotherapy for small liver cancer
This trial tests a combination of targeted radiation (SBRT) and immunotherapy for people with small liver cancers that have come back or are still present after prior treatment. It aims to see if this approach can better control the cancer without using heavy chemotherapy.
Guangzhou, GuangdongAges 18–75 - NCT06313541RecruitingPhase 2
Adaptive radiation with immunotherapy for advanced lung cancer
This trial is testing a combination of immunotherapy and targeted radiation for people with advanced lung cancer that has no targetable gene changes. The goal is to see if adjusting radiation based on how well the tumor responds can improve outcomes.
ShanghaiAges 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
