It aims to improve outcomes for patients with high-risk features.
ShanghaiAges 18–70 - NCT06238882Recruiting
Nitroglycerin plus radiation for EGFR-mutant lung cancer with brain spread
This trial tests whether adding nitroglycerin (a medicine that widens blood vessels) to standard whole-brain radiation helps improve treatment for lung cancer that has spread to the brain. It is for people with a specific gene change (EGFR mutation) in their cancer.
Mexico City, Mexico CityAges 18–85 - NCT06218420RecruitingPhase 2
Radiation to bridge to liver transplant
This study tests whether a precise type of radiation (called stereotactic body radiotherapy or SBRT) can be used as a 'bridge' to keep your liver cancer from growing while you wait for a liver transplant. It may help more people stay healthy enough to receive a transplant.
ParisAges 18 years+ - NCT06210490RecruitingPhase 2
Antibody-drug combo with radiation for HER2+ UTUC after surgery
This trial tests a combination of an antibody-drug conjugate (Disitamab Vedotin) plus radiation therapy after surgery to prevent upper tract urothelial cancer from coming back. It is for patients with HER2-positive tumors and high-risk features who cannot receive cisplatin chemo.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06204094RecruitingPhase 2
Preserving the anus with chemo, immunotherapy, and radiation for rectal cancer
This trial tests a treatment plan that combines chemotherapy, immunotherapy, and radiation before surgery for patients with middle or low rectal cancer. The goal is to shrink the tumor enough to avoid removing the anus, preserving bowel function.
Jinhua, ZhejiangAges 18–75 - NCT06177093Recruiting
Higher dose prostate radiation with MRI guidance
This study tests a higher dose of radiation for prostate cancer using an MRI-guided machine (MR-Linac). It aims to see if a more targeted dose can be safely given to the tumor while protecting healthy tissue.
Toronto, OntarioAges 18 years+ - NCT06160557Enrolling by invitation
Radiation after endoscopic surgery for superficial esophageal cancer
This trial tests if adding radiation therapy after endoscopic surgery (ESD) helps people with early-stage esophageal cancer that had certain high-risk features, like deeper invasion or positive margins. It aims to improve outcomes for those who didn't get a complete cure with surgery alone.
Fuzhou, FujianAges 18–75 - NCT06137274RecruitingPhase 2
Adaptive radiation boost for head and neck cancer
This trial tests a new way of giving radiation therapy, called adaptive radiation boost, for people with head and neck cancer. The goal is to see if this approach can better target the cancer and possibly improve outcomes.
Tampa, FloridaAges 18 years+ - NCT06150417RecruitingPhase 2
Study of extra radiation for prostate cancer spread to few spots
This study tests whether adding a type of high-precision radiation (MDRT) to standard hormone therapy works better for men with prostate cancer that has spread to just a few places. It is for patients who are newly diagnosed and on long-term hormone therapy.
New York, New YorkAges 18 years+ - NCT06133062RecruitingPhase 2
Study of atezolizumab, bevacizumab, and proton therapy for advanced liver cancer
This trial tests a combination of two immunotherapy drugs (atezolizumab and bevacizumab) plus targeted proton radiation for liver cancer that cannot be removed by surgery. The goal is to see if this approach can shrink tumors and improve outcomes for people with intermediate or advanced stage liver cancer.
Taoyuan City, TaiwanAges 18 years+ - NCT06114108Recruiting
Adding local treatment to drug therapy for stage IV lung cancer
This trial compares continuing drug therapy alone versus adding local treatments (surgery or radiation) for people with stage IV lung cancer that has responded to initial treatment but still has a few remaining spots (oligometastatic). The goal is to see if targeting those spots with local therapy helps control the cancer longer.
AarauAges 18 years+ - NCT06102057RecruitingPhase 2
PET-guided small volume chemoradiation with immunotherapy for lung cancer
This trial tests a new combination of chemotherapy, radiation, and immunotherapy (durvalumab) for people with stage III non-small cell lung cancer that cannot be removed with surgery. The goal is to see if giving a smaller, more focused radiation dose can be just as effective with fewer side effects.
DresdenAges 18 years+ - NCT06066333RecruitingPhase 2
