Recruiting studies
- NCT06159335RecruitingPhase 3

Study of retifanlimab, bevacizumab, and radiation for recurrent glioblastoma
This trial tests a combination of immunotherapy (retifanlimab), a targeted drug (bevacizumab), and low-dose radiation for people whose glioblastoma has come back. The goal is to see if this treatment can help shrink or slow the tumor.
Scottsdale, ArizonaAges 18 years+ - NCT06165653Recruiting

Immunotherapy plus chemoradiation for limited spread SCLC
This trial tests a combination of an immunotherapy drug (adebrelimab) plus standard chemotherapy and radiation for people with extensive-stage small cell lung cancer that has only spread to a few places. The goal is to see if this approach can help control the cancer better.
GuangzhouAges 18–75 - NCT06220435Recruiting
Radiation therapy for very high-risk localized prostate cancer
This trial tests radiation therapy for men with very high-risk prostate cancer that hasn't spread. It aims to see if targeting the tumor with radiation can help control the cancer in this highest risk group.

Comparing chemoimmunotherapy vs chemoradiation for advanced cervical cancer before surgery
This trial tests whether a combination of chemotherapy and immunotherapy (pembrolizumab) before surgery works better than standard chemoradiation for locally advanced cervical cancer. It may help shrink tumors more effectively.
Hefei, AnhuiAges 18–70 - NCT06297265Recruiting
Gentle breast massage after lumpectomy for breast cancer
This trial studies whether a special gentle massage technique (manual lymphatic drainage) can help women who have had breast-conserving surgery and will receive whole breast radiation. The goal is to see if it reduces side effects and improves recovery.
Los Angeles, CaliforniaAges 18 years+ - NCT06313203RecruitingPhase 2
Chemotherapy with or without liver-directed treatment for bile duct cancer
This trial tests whether adding a liver-directed treatment (HAI floxuridine or SIRT) to standard chemotherapy (GemOx) is more effective for people with bile duct cancer inside the liver that cannot be removed by surgery. It may be an option for those whose cancer is only in the liver or nearby lymph nodes.
Oslo, OsloAges 18 years+ - NCT06323460RecruitingPhase 2
Less Radiation for HPV Throat Cancer Guided by a Blood Test
This study tests a way to use less radiation for HPV-related throat cancer. Doctors will adjust your treatment based on a simple blood test that tracks cancer DNA, so you may get only the treatment you need.
Columbus, OhioAges 18 years+ - NCT06328686RecruitingEarly Phase 1
Arginine and whole brain radiation for brain metastases
This trial tests whether taking arginine (an amino acid) during whole brain radiation therapy can help people with brain metastases from any type of cancer. It looks at how the treatment affects the body and may improve outcomes.
Atlanta, GeorgiaAges 18 years+ - NCT06344130RecruitingPhase 1
Shorter radiation for recurrent glioblastoma
This trial tests a new, shorter course of radiation therapy (called hypofractionation) for people with glioblastoma that has come back. It is for patients who have already had radiation and are doing well enough to consider another round.
Bethesda, MarylandAges 18–120 - NCT06355050Recruiting
Short, intense radiation for prostate cancer
This trial tests a very short course of daily radiation that adapts to your body's changes. It aims to be just as effective as standard treatment but more convenient.
JenaAges 18–120 - NCT06377696RecruitingPhase 2
Metformin study for brain tumor survivors after radiation
This study tests whether metformin, a common diabetes medicine, can help protect thinking and memory skills in people who have had radiation for a brain tumor. You will use a smartwatch and take online tests from home to track your progress.
Rochester, MinnesotaAges 18 years+ - NCT06406530Recruiting
Applying PRF gel before radiation for head and neck cancer
This trial tests whether applying a special gel made from your own blood (platelet-rich fibrin, or PRF) to the tooth sockets after extraction can help the gums heal better before radiation therapy starts. It's for people with head and neck cancer who need to have teeth removed on both sides of the jaw.
Giessen, HesseAges 18–99 - NCT06467097RecruitingPhase 3
Drug therapy vs. drug therapy plus radiation for limited kidney cancer
This trial tests whether adding radiation to standard drug therapy helps control kidney cancer that has spread to a few spots (oligometastatic). It is for people with clear cell renal cell carcinoma who have up to 5 metastases.
SeoulAges 20–80 - NCT06470282RecruitingPhase 1/Phase 2
Drug combo plus radiation for muscle-invasive bladder cancer
This trial tests a combination of two drugs (enfortumab vedotin and pembrolizumab) plus radiation therapy for people with bladder cancer that has grown into the muscle layer. The goal is to see if this treatment can kill the cancer while avoiding the need for bladder removal surgery.
San Francisco, CaliforniaAges 18 years+ - NCT04945642Recruiting
Radiation combination therapy for intermediate to high-risk prostate cancer
This trial studies a combination of two radiation types—high-dose-rate brachytherapy and stereotactic body radiotherapy—to treat certain intermediate- to high-risk prostate cancers. It may help by aiming radiation closely at the prostate while also targeting the cancer from outside the body.
Los Angeles, CaliforniaAges 18 years+ - NCT07693140RecruitingPhase 1/Phase 2
Low-dose radiation therapy for Alzheimer's disease
This trial tests if very low doses of radiation to the brain can reduce inflammation and slow memory loss in people with Alzheimer's or similar dementias. It involves monthly clinic visits for a year.

WuhanAges 18 years+ - NCT06496256Recruiting
Barrigel gel for radiation after prostate removal
This trial tests a gel placed in the rectum during radiation therapy to protect healthy tissue after prostate removal. It is for men whose prostate cancer has come back (PSA rise) and who need radiation to the prostate bed.

How cancer treatments affect hearing and thinking
This study looks at how common cancer treatments (certain chemotherapies and radiation to the head and neck) affect hearing in noisy places, thinking skills, and quality of life related to hearing. It aims to understand and possibly reduce these side effects.

Common questions
- Are there clinical trials for radiation therapy?
- Yes. Clin2 currently lists 686 recruiting radiation therapy 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 therapy 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 therapy 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.
