Radiation and Lutetium PSMA for locally advanced prostate cancer
This study tests a combination of focused radiation (SBRT) and a targeted radioactive drug (Lutetium PSMA) for men with prostate cancer that has spread to nearby lymph nodes or has high-risk features but has not yet reached distant organs. The goal is to see if this approach is safe and effective.
Cleveland, OhioAges 18 years+ - NCT06579547Recruiting
Testing MRI instead of CT for joint imaging
This study tests if a new, radiation-free MRI method can replace standard CT scans for checking joint problems like arthritis. You would get both an MRI and a CT scan, and researchers compare the results to see if the MRI works just as well without radiation.
ZurichAges 18 years+ - NCT06586255RecruitingPhase 1

Geriatric assessment for older adults with lung cancer getting chemotherapy and radiation
This trial tests whether a special geriatric assessment can help manage side effects for adults aged 60 and older with non-small cell lung cancer who are starting a new treatment plan that includes chemotherapy and radiation. It aims to improve quality of life and treatment outcomes.
Duarte, CaliforniaAges 60 years+ - NCT06611150RecruitingPhase 1
Chemo and radiation for advanced nasopharyngeal cancer
This trial tests whether a specific chemotherapy drug (nab-paclitaxel) given along with targeted radiation therapy can help people with stage III or IVa nasopharyngeal cancer. The goal is to improve treatment outcomes while managing side effects.
Guangzhou, GuangdongAges 18–70 - NCT06623656RecruitingPhase 2
Pre-surgery treatment comparison for non-small cell lung cancer
This trial compares two treatment approaches before surgery for non-small cell lung cancer (NSCLC): radiation plus immunotherapy versus chemotherapy plus immunotherapy. The goal is to see which combination works better to shrink the tumor before it is removed.
New York, New YorkAges 18 years+ - NCT06633601RecruitingPhase 1
Ultrasound and microbubbles with radiation for breast cancer
This trial tests a new way to combine radiation therapy with ultrasound and tiny bubbles to treat breast cancer that has spread to the chest wall or is advanced. It aims to make radiation more effective and safer.
Toronto, OntarioAges 18 years+ - NCT06634056RecruitingPhase 2
Preventing lung inflammation during chemoradiation for stage III lung cancer
This trial tests whether two medicines, pentoxifylline and vitamin E, can help prevent a type of lung inflammation called pneumonitis in people with stage III non-small cell lung cancer who are getting chemoradiation and a checkpoint inhibitor. These medicines are already used for other conditions and may lower the risk of this side effect.
Toronto, OntarioAges 18 years+ - NCT06635980RecruitingPhase 2
Radiation before or after breast cancer surgery
This trial compares two ways of giving radiation for breast cancer that has not spread: before or after surgery. It aims to see if giving radiation first might work as well or better.
Scottsdale, ArizonaAges 18 years+ - NCT06639165Recruiting
Radiation outcomes in children and young adults with pediatric cancers
This study looks back at past patients and follows new patients to understand how well radiation therapy works and what side effects it causes in children, teens, and young adults (and some older adults with childhood-type cancers) treated at the Pediatric Radiotherapy Unit in Aviano. It helps doctors learn more about the benefits and risks of radiation for these cancers.
Aviano, PordenoneAges Any age - NCT06640959Recruiting
Bowel health study for prostate cancer radiation
This study tests whether a daily drink can help reduce bowel side effects caused by radiation for prostate cancer. If you are about to start radiation for intermediate to high-risk prostate cancer, you may be able to join.
Manchester, Greater ManchesterAges 18 years+ - NCT06642220RecruitingPhase 2
Y-90 radioembolization for kidney cancer
This trial tests a procedure called Y-90 radioembolization for patients with kidney cancer tumors larger than 4 cm who cannot have or choose not to have surgery. The treatment delivers tiny radioactive beads through a blood vessel to the tumor to destroy cancer cells while limiting damage to healthy tissue.
London, OntarioAges 18 years+ - NCT06648148Recruiting
Molecular markers for radiation response in breast cancer
This trial looks for biomarkers (biological signs) in breast tissue that might predict how well breast cancer responds to radiation therapy. It is for patients with ductal carcinoma in situ (DCIS) who are scheduled to receive radiation after surgery.
LjubljanaAges 18–75 - NCT06650579RecruitingPhase 3
Heart safety study of relugolix vs leuprolide for prostate cancer
This trial compares two hormone therapy combinations for men with prostate cancer that hasn't spread. The goal is to see if a newer oral medication (Relugolix) plus abiraterone works better than the standard injectable therapy (Lupron) plus abiraterone, while also checking heart safety.
Atlanta, GeorgiaAges 18 years+ - NCT06651853RecruitingPhase 2
Radiation therapy with lenalidomide and glofitamab for DLBCL
This trial tests a combination of radiation therapy, lenalidomide, and glofitamab for people with a type of lymphoma called DLBCL that has not responded to or has returned after initial treatment. The goal is to see if this combination can help when other treatments have failed.

Common questions
- Are there clinical trials for radiation?
- Yes. Clin2 currently lists 1,049 recruiting radiation studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a radiation trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a radiation trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
