Boston, MassachusettsAges 18 years+ - NCT06325995Recruiting
Short radiation course after prostate surgery for rising PSA
This trial tests a shorter, stronger course of radiation (hypofractionated radiotherapy) given after prostate removal surgery. It may help people whose PSA levels rise again after surgery, aiming to reduce side effects and improve outcomes.
Shanghai, Shanghai MunicipalityAges Any age - NCT04754321RecruitingPhase 1
Test immunotherapy with salvage surgery and IORT for head and neck cancer
This Phase 1 trial tests a new plan that combines immunotherapy with surgery, plus a targeted radiation treatment called IORT. It is for people whose head and neck squamous cell cancer has come back or never fully went away and can be operated on. The goal is to shrink or control the cancer and see how safe the approach is.
Columbus, OhioAges 18 years+ - NCT06814496RecruitingPhase 1/Phase 2
Radiation and immunotherapy combo for DLL3-positive cancers
This trial combines radiation with an immunotherapy drug called tarlatamab to treat cancers that make a protein called DLL3. The goal is to see if this combination works better than either treatment alone for people with certain types of lung cancer and other tumors that have not responded to prior therapy.
Tucson, ArizonaAges 18–99 - NCT03422302Recruiting
CPAP or breath-holding to reduce lung tumor motion
This study looks at whether using a CPAP breathing device or deep breath-holding can keep lung tumors from moving during targeted radiation. The goal is to improve safety and accuracy of stereotactic body radiation for lung cancer.
Houston, TexasAges 18 years+ - 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+ - NCT06625034RecruitingPhase 3
Comparing two radiation planning methods for prostate cancer
This trial tests two ways to plan radiation treatment for prostate cancer: one using a computer program (RapidPlan) and the other using human experts. The goal is to see if the computer-assisted method works as well or better.
Scottsdale, ArizonaAges 18 years+ - NCT02344121Recruiting
Study changes after radiation therapy
This study looks at how radiation treatment effects and measurements can change within a treatment session and across different sessions. It may help doctors improve how radiation therapy is planned and delivered.
Milwaukee, WisconsinAges Any age - NCT03706027Recruiting
Compare two radiation timing plans for early lung cancer
This trial tests whether two different schedules (timing) of radiation have different side effects in people with early-stage non-small cell lung cancer. It may help reduce or better understand treatment toxicity while still treating the cancer.
Rochester, New YorkAges 18 years+ - NCT06205316RecruitingPhase 3
Radiation therapy for returning or limited-spread prostate cancer
This trial compares two types of radiation therapy for prostate cancer that has come back or spread to a few places after surgery. The goal is to see which radiation schedule works better with fewer side effects.
Scottsdale, ArizonaAges 18 years+ - NCT06770582RecruitingPhase 2
Adding immunotherapy to radiation for bladder cancer
This trial tests whether adding the immunotherapy drug pembrolizumab to radiation therapy works as well as or better than the usual chemotherapy given with radiation for a type of bladder cancer that has not invaded the muscle. It is for people whose cancer came back or has high-risk features and who would otherwise need to have their bladder removed.
Fayetteville, ArkansasAges 18 years+ - NCT07348887Recruiting
Daily adaptive radiotherapy for head and neck cancer to spare salivary glands
This trial tests a new daily adaptive radiotherapy technique that aims to spare the submandibular salivary glands during head and neck cancer treatment. It may help reduce dry mouth after radiation.
Toronto, OntarioAges 18 years+ - NCT06563479RecruitingPhase 3
Personalized vs. standard radiation for HPV-positive throat cancer
This trial compares a personalized, shorter course of radiation therapy to the standard longer course for people with HPV-positive throat cancer. The goal is to see if personalized treatment is just as effective while reducing side effects.
Hartford, ConnecticutAges 18 years+ - NCT07052669RecruitingPhase 3
Shorter Chemo-Radiation Plus Immunotherapy for Stage III Lung Cancer
This trial tests a new schedule of chemo-radiation (fewer, stronger sessions) followed by an immunotherapy drug called tislelizumab. The goal is to see if this approach works better than the standard longer schedule for people with stage III lung cancer that can't be surgically removed.
Chongqing, Chongqing MunicipalityAges 18–75 - NCT04068649RecruitingPhase 2
Single high-dose radiation vs standard palliative radiation
This Phase 2 study compares a one-time, high-dose radiation treatment (SBRT) with the usual, shorter-course palliative radiation. The goal is to see which approach better relieves symptoms from metastatic (spread) cancer.
