This trial tests an adaptive, image-guided radiation plan for anal canal squamous-type cancers. It may help deliver effective treatment while adjusting the radiation based on how your body and tumor respond.
New York, New YorkAges 18 years+ - NCT05833867RecruitingPhase 1
Bladder cancer trial combining radiation and Sacituzumab
This Phase 1 study tests whether a new bladder-cancer treatment plan—radiation given at the same time as sacituzumab govitecan—can help people with muscle-invasive bladder cancer without starting with traditional chemo/radiation. Because it’s early-stage, the main goal is safety and learning the best way to use this combination to preserve the bladder.
Cleveland, OhioAges 18 years+ - NCT05838599RecruitingEarly Phase 1
Imiquimod cream plus local radiation for skin lymphoma lesions
This early-stage study tests whether a cancer-killing cream (imiquimod) combined with targeted local radiation can shrink and control mycosis fungoides skin lesions. It may help people whose skin lymphoma has not responded to at least one prior standard treatment.
Chicago, IllinoisAges 18–90 - NCT05837767Recruiting
Radiation study for tumors that spread to soft tissue areas
This study looks at how a planned form of palliative radiation therapy treats certain solid cancers that have spread outside the brain to larger soft-tissue areas. It may help shrink tumors and relieve symptoms, but it also asks you to meet specific safety and treatment-timing rules.
Basking Ridge, New JerseyAges 18 years+ - NCT05798845RecruitingPhase 2
Toripalimab plus radiation before surgery for stage II–IIIA lung cancer
This trial studies whether adding toripalimab (an immunotherapy medicine) to radiation can improve outcomes for people with operable stage II to IIIA non-small cell lung cancer. It’s designed for cancers that can be fully removed with surgery, and it aims to see if this combination helps more than radiation alone/standard care.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05710679Recruiting
Blood test predicts leftover cancer after intensified head and neck radiation
This study uses a blood test to see whether cancer DNA is still detectable after a stronger combination of radiation and chemotherapy for locally advanced head and neck cancer. The goal is to predict who may have “residual” (remaining) disease and help guide future care.
Clermont-Ferrand, Puy-de-DômeAges 18–80 - NCT05709782RecruitingPhase 2
MR-guided targeted radiation for limited-spine spinal metastasis
This Phase 2 study tests an MRI-guided radiation machine (an MR LINAC) to deliver very focused treatment to spine tumors. It may help by improving accuracy while treating up to a small number of spine levels affected by cancer.
Houston, TexasAges 18 years+ - NCT05686798RecruitingPhase 1
Gene therapy plus radiation for recurring brain tumor
This early-phase study tests a “suicide gene” therapy delivered by a virus along with radiation for adults whose high-grade brain tumor has come back or grown again. The goal is to see if the treatment is safe and can help control the tumor.
Detroit, MichiganAges 18 years+ - NCT05674396RecruitingPhase 2
Short-course radiation to ease symptoms from head and neck cancer
This Phase 2 trial tests a specific, shorter type of focused radiation to help relieve symptoms from head and neck squamous cell carcinoma. It compares two radiation timing/planning approaches to see which better improves comfort and quality of life.
Houston, TexasAges 18 years+ - NCT04430452RecruitingPhase 2
Durvalumab with or without tremelimumab after liver radiation
This study tests whether the immunotherapy drugs durvalumab (with or without tremelimumab) can help control hepatocellular carcinoma (liver cancer) after you receive palliative, targeted radiation. It especially focuses on people whose cancer continued to grow after, or without, certain prior immune therapies.
San Francisco, CaliforniaAges 18 years+ - NCT05640999RecruitingPhase 2
Trial for early uterine cancer with POLE mutation after surgery
This Phase 2 trial studies an added (adjuvant) treatment for early-stage uterine cancer that has a specific genetic change called POLE mutation and does not have a p53 abnormal pattern. The goal is to lower the risk of the cancer coming back after surgery.
Anchorage, AlaskaAges 18 years+ - NCT05671458Recruiting
Imaging guidance during head and neck tumor surgery plus radiation
This trial tests whether advanced imaging used during surgery can better guide where surgeons remove head-and-neck tumors. It also studies how this approach works alongside planned postoperative radiation therapy, which may be needed for more advanced tumors.
HeidelbergAges 18 years+ - NCT05673148RecruitingPhase 2
Adding targeted tumor treatment to standard therapy for limited metastatic colorectal cancer
This trial tests whether adding a precise, targeted treatment to destroy remaining cancer spots (called total ablative therapy) after initial chemotherapy can improve outcomes for people with limited metastatic colorectal cancer. It aims to see if this extra treatment is safe and effective.
Kingman, ArizonaAges 18 years+ - NCT05634889Recruiting
Personalized breast radiation for limited lymph-node spread
This trial studies a tailored form of radiation treatment for some people with early breast cancer whose sentinel lymph-node biopsy shows cancer in 1–2 nodes. It may help improve local control while guiding the best radiation approach for your specific situation.
HelsinkiAges 18 years+ - NCT05589701Recruiting
Compare two radiation plans for painful spinal cancer spread
This study compares two different radiation approaches—SBRT and CRT—for people with painful cancer that has spread to the spine. It may help determine which plan controls pain and tumor growth while limiting side effects to nearby organs.
Toronto, OntarioAges 18–100 - NCT05580562RecruitingPhase 3
ONC201 for newly diagnosed H3 K27M brain tumor after radiation
This study tests whether ONC201 (also called ONC201) can improve outcomes for people with a newly diagnosed H3 K27M–mutant diffuse brain tumor after they finish radiation. It looks for safety and whether treatment can help control the tumor.
Phoenix, ArizonaAges Any age - NCT05534438RecruitingPhase 2
Tested targeted radiation plus usual drug treatment in metastatic breast cancer
This Phase 2 study tests whether adding a very focused type of radiation to standard drug treatment can better control metastatic breast cancer. It is for people whose cancer is only progressing in one spot, seen on a PET scan.
Basking Ridge, New JerseyAges 18 years+ - NCT05546827RecruitingPhase 2
Pre-surgery radiation plus immunotherapy for mucosal melanoma
This Phase 2 trial tests giving radiation and immunotherapy before surgery for mucosal melanoma in the nose/sinuses or rectum. It may help shrink the tumor and improve outcomes while aiming to control the disease locally and in nearby areas.
Houston, TexasAges 18 years+ - NCT05508464Recruiting
Test targeted radiation to control many metastases safely
This study tests whether a focused, high-precision type of radiation can control many cancer spread-out spots (“metastases”) at the same time, while keeping side effects acceptable. It may help people with many metastases live longer or have better disease control by aiming treatment at every treatable spot.
London, OntarioAges 18 years+ - NCT05529251RecruitingPhase 2
Lower-dose treatment for small stage II seminoma
