Columbus, OhioAges 18 years+ - NCT06214572RecruitingPhase 2/Phase 3
Radiation Therapy for Advanced Gallbladder Cancer
This trial tests a type of radiation therapy for people with advanced gallbladder cancer that cannot be removed by surgery. It is for those whose cancer has not spread to other parts of the body and has stayed stable or improved after initial chemotherapy.
Mumbai, MaharashtraAges 18 years+ - NCT07122713Recruiting
Radiation therapy for inoperable breast cancer
This trial tests whether definitive radiation therapy can effectively treat breast cancer that cannot be surgically removed. It may be an option for people whose cancer is inoperable or who choose not to have surgery.
Stony Brook, New YorkAges 18 years+ - NCT04782752Recruiting
Radiation before lung transplant to help stop lung cancer spread
This study tests a focused, low-dose type of radiation given before a lung transplant. The goal is to help your immune system recognize and attack cancer cells (called “radiovaccination”) and improve outcomes for people who cannot get curative treatment with surgery or SBRT alone.
Toronto, OntarioAges 18 years+ - NCT04983095Recruiting
Targeted radiation for a few prostate cancer metastases
This trial looks at whether a precise form of radiation (stereotactic body radiotherapy) can control a small number of prostate cancer spots seen on a special scan (PSMA PET/CT). It may help by treating limited metastases while avoiding unnecessary treatment elsewhere.
Lund, LundAges 18 years+ - NCT04977375RecruitingPhase 1/Phase 2
Anti–PD-1 treatment plus focused radiation for recurrent glioblastoma
This trial tests a cancer-immunotherapy medicine (an anti–PD-1 antibody, similar to pembrolizumab) combined with precisely targeted radiation to treat glioblastoma that has come back or progressed. It may help your immune system recognize and attack the tumor while the radiation targets the cancer.
Los Angeles, CaliforniaAges 18 years+ - NCT05491226RecruitingPhase 2
Pembrolizumab plus radiation and myeloid-targeting for high-risk breast cancer
This trial studies whether adding pembrolizumab (an immune “unlocking” drug) to radiation and another treatment that targets certain immune cells can improve outcomes for women with high-risk, early-stage triple negative breast cancer. You may be considered if your cancer has signs that it may respond less to immunotherapy on its own.
Los Angeles, CaliforniaAges 18 years+ - NCT06554158Recruiting
Lowering radiation for low-risk HPV throat cancer patients
This trial tests whether giving less radiation after surgery is safe and effective for people with early-stage HPV-related throat cancer. It aims to reduce side effects while still controlling the cancer.
Washington D.C., District of ColumbiaAges 18 years+ - NCT06664996RecruitingPhase 2
Immunotherapy plus radiation before surgery for liver cancer with portal vein tumor clot
This trial tests combining an immunotherapy drug (sintilimab) with focused radiation (SBRT) before surgery for liver cancer that has spread into a branch of the portal vein. The goal is to see if this combination can shrink the tumor and make surgery more successful.
Chengdu, SichuanAges 18 years+ - NCT06843551RecruitingPhase 2
Testing a new immunotherapy combo for advanced pancreatic cancer
This trial is testing two immunotherapy drugs (balstilimab and botensilimab) to see if they can shrink tumors in people with advanced pancreatic cancer that has worsened after at least one prior treatment. If you have microsatellite stable (MSS) disease, you may be eligible.
Miami, FloridaAges 18 years+ - NCT06870942RecruitingPhase 2
Radiation therapy for liver cancer that progresses after first immunotherapy
