Shorter radiation course for newly diagnosed glioblastoma
This trial tests a shorter, more intense course of radiation therapy (hypofractionated radiotherapy) for people with newly diagnosed glioblastoma who have had surgery. The goal is to see if this approach is safe and works well for treating the tumor.
Changchun, JilinAges 18–70 - NCT07545967RecruitingPhase 1
Re-radiation and Chidamide for Recurrent Head and Neck Cancer
This trial tests combining re-radiation (radiation therapy given a second time) with a drug called chidamide to treat head and neck cancer that has come back after previous radiation. The goal is to see if this combination can help patients whose cancer cannot be removed by surgery or who cannot have surgery.
Chengdu, SichuanAges 18–75 - NCT07527884Recruiting
Radiation therapy after spine tumor removal surgery
This trial tests whether radiation therapy after surgery to remove cancer that has spread to the spine improves outcomes. You may be a good fit if you recently had this surgery and your doctors think you'll live at least 6 more months.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07512154Recruiting
Precision Brain Tumor Radiotherapy Using Advanced MRI
This study tests a new way to plan and deliver radiation therapy for glioblastoma (an aggressive brain tumor) using special MRI scans to target cancer cells more precisely. The goal is to improve treatment effectiveness while reducing harm to healthy brain tissue.
Baltimore, MarylandAges 18 years+ - NCT07505173RecruitingPhase 2
Targeted radiation plus osimertinib for brain metastases from EGFR-mutant lung cancer
This trial tests adding a brain-sparing radiation technique to the targeted therapy drug osimertinib for people with EGFR-mutant lung adenocarcinoma that has spread to the brain and is causing symptoms. The goal is to see if this combination can better control the brain tumors while protecting the hippocampus, a key memory area.
TianjinAges 18–75 - NCT07500701RecruitingPhase 3
Comparing two radiation schedules for rising PSA after prostate surgery
This trial is testing two types of radiation therapy for men whose PSA level rises after prostate removal, but without clear signs of cancer spread on a PSMA PET scan. The goal is to see which radiation schedule works better to control the cancer.
Seoul, Gangnam-guAges 20 years+ - NCT06765616RecruitingPhase 2
Immunotherapy with chemo and radiation for rectal cancer before surgery
This trial tests a combination of a PD-L1 inhibitor (adebrelimab), short-course radiation, and chemotherapy given before surgery for locally advanced rectal cancer. The goal is to see if this approach can shrink the tumor and improve outcomes.
Jinan, ShandongAges 18–85 - NCT07483658Recruiting
Salvage pelvic radiotherapy: 20 vs 25 sessions for recurring prostate cancer
This trial compares two schedules of pelvic radiotherapy for men whose prostate cancer has returned after surgery. Both schedules aim to control the cancer with fewer visits for one of them.
Gatineau, QuebecAges 18 years+ - NCT07477626RecruitingPhase 3
Radiation therapy after prostate surgery for advanced prostate cancer
This study tests whether radiation therapy to the pelvis after prostate removal helps men whose cancer was found in nearby lymph nodes. The goal is to prevent cancer from coming back and improve survival.
Dongguan, GuangdongAges 18 years+ - NCT07448077RecruitingPhase 2
Short radiation with immunotherapy for rectal cancer
This trial tests a combination of short-course radiation, chemotherapy, and an immunotherapy drug (Enlonstobart) for patients with a specific type of rectal cancer called pMMR. It aims to see if this approach can shrink tumors before surgery and improve outcomes.
Shijiazhuang, HebeiAges 18 years+ - NCT07447570RecruitingPhase 2
Iparomlimab and Tuvonralimab plus radiation and chemo for head and neck cancer
This trial tests a combination of two immunotherapy drugs (Iparomlimab and Tuvonralimab) with low-dose radiation and chemotherapy for advanced head and neck cancer. It aims to see if this approach can help patients who have not had prior treatment for their cancer.
Hangzhou, ZhejiangAges 18–75 - NCT07443397RecruitingPhase 3
Anlotinib plus whole-brain radiation for SCLC brain metastases
This trial tests whether combining Anlotinib (a targeted drug that blocks tumor blood vessel growth) with whole-brain radiation can better control brain metastases in small cell lung cancer patients. It is for people with up to 10 brain tumors who have not had brain radiation before.
Beijing, Beijing MunicipalityAges 18–80 - NCT07426055RecruitingPhase 2/Phase 3
Prostate cancer radiation boost comparison study
This trial compares two types of radiation treatments for prostate cancer that has not spread to lymph nodes or other parts of the body. It tests whether adding a higher dose of radiation to the main tumor helps control the cancer better than standard radiation alone.
Zamość, Lublin VoivodeshipAges 18 years+ - NCT07391982Recruiting
Short course MRI-guided radiation for prostate cancer
This trial tests a shorter radiation plan using an MRI machine to guide treatment. The goal is to see if two high-dose sessions work just as well as longer treatment, with fewer side effects. It is for men with low or intermediate risk prostate cancer.
AmsterdamAges 18 years+ - NCT06831773Recruiting
Carbon ion radiation for high-grade brain tumors
This trial tests a precise type of radiation called carbon ion radiotherapy for people with aggressive brain tumors (high-grade gliomas). It aims to see if this treatment is safe and effective for patients who have not had radiation to the head before.
Wuwei, GansuAges 14–80 - NCT06831903Recruiting
Radiation therapy for head and neck cancer
This trial is studying a type of radiation therapy for head and neck cancer. It aims to find the best way to deliver radiation to help treat the cancer effectively.

Low-dose radiation and immunotherapy before surgery for head and neck cancer
This trial tests a combination of low-dose radiation and an immunotherapy drug (similar to Keytruda) given before surgery for advanced head and neck cancer. The goal is to see if this approach can shrink tumors and improve outcomes.
GuangdongAges 18–75 - NCT07354594RecruitingPhase 2

Montreal, QuebecAges Any age - NCT06854679Recruiting
MRI-guided radiation for rectal cancer
This trial tests a new way of giving radiation therapy for rectal cancer, using MRI scans to aim the radiation more precisely. It's for people who need chemotherapy and radiation before surgery, and it aims to make treatment more effective while reducing side effects.
Sutton, SurreyAges 18 years+ - NCT07339774RecruitingPhase 2
Traditional Chinese medicine for mouth sores from radiation
This trial tests whether a traditional Chinese medicine can help prevent or reduce the severity of mouth sores caused by radiation therapy for head and neck cancer. If you are scheduled to get radiation for non-spreading head or neck cancer, this treatment might help protect your mouth.
Chengdu, SichuanAges 18–65 - NCT07339488RecruitingPhase 2
Low-dose radiation and immunotherapy to shrink hard-to-remove esophageal cancer
This trial tests a treatment approach that combines low-dose radiation with immunotherapy and chemotherapy for people with esophageal cancer that is hard to remove with surgery. The goal is to shrink the tumor enough to make surgery possible, which could improve outcomes.

Common questions
- Are there clinical trials for radiotherapy?
- Yes. Clin2 currently lists 1,308 recruiting radiotherapy 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 radiotherapy 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 radiotherapy 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.
