- 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.

Immunotherapy vs. chemo for MS anal cancer trial
This trial tests sintilimab (a type of immunotherapy) against mitomycin plus chemotherapy with radiation for anal cancer that hasn't spread. It aims to find a better treatment with fewer side effects.
Beijing, Beijing MunicipalityAges 18–75 - 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.
Winter Park, FloridaAges 50 years+ - NCT06488391Recruiting

This trial tests whether a special breathing exercise can help you hold your breath longer during radiation therapy for breast cancer. It may make treatment more precise and help protect nearby organs.
Hangzhou, ZhejiangAges Any age - NCT06494995RecruitingPhase 2
AK104 and low-dose radiation for advanced head and neck cancer
This trial tests a new immunotherapy drug called AK104 (cadonilimab) combined with low-dose radiation for people with head and neck or nasopharyngeal cancer that has come back or spread and no longer responds to first treatment. The goal is to see if this combination can shrink tumors or stop them from growing.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06498154RecruitingPhase 2
Skipping breast surgery for some patients after chemo
This trial tests whether women with certain aggressive breast cancers (HER2-positive without hormone receptors, or triple-negative) can safely skip breast surgery if chemotherapy makes their tumor completely disappear. The goal is to avoid surgery and its side effects when it may no longer be needed.
TianjinAges 18–70 - NCT06498752RecruitingPhase 2
MRD-guided consolidation therapy after radiation for esophageal cancer
This trial looks at whether a treatment guided by a blood test (MRD) after radiation can help prevent esophageal cancer from coming back. It tests a personalized approach to decide if more treatment is needed.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06501391RecruitingPhase 2
Brain radiation plus chemo-immunotherapy for untreated NSCLC with stable brain metastases
This trial tests whether combining brain radiation with chemotherapy and immunotherapy can help people with advanced lung cancer that has spread to the brain but has not yet been treated. It is for those whose tumors do not have certain gene mutations (EGFR, ALK, ROS1).
ShanghaiAges 18 years+ - NCT06501378RecruitingPhase 2
Brain radiation plus chemotherapy and immunotherapy for lung cancer brain metastases
This trial tests a combination of radiation to the brain plus chemotherapy and immunotherapy (anti-PD-1/PD-L1) for people with newly diagnosed non-small cell lung cancer that has spread to the brain. It is for those whose tumors do not have common driver mutations and whose brain metastases are causing symptoms.
ShanghaiAges 18 years+ - NCT06506435Recruiting
Radiation therapy education using virtual reality
This study tests whether watching a virtual reality video before radiation therapy helps you understand the treatment better. It is for people with cancer who are starting radiation therapy at the University of Miami.
Miami, FloridaAges 18 years+ - NCT06507683Recruiting
Radiation plus ripretinib for advanced GIST
This trial tests whether adding radiation therapy to the drug ripretinib can help people with advanced gastrointestinal stromal tumors (GIST) that can't be removed by surgery and have stopped responding to other treatments. It aims to see if this combination is safe and effective.
Chongqing, Chongqing MunicipalityAges 18–75 - NCT06508567Recruiting
MRI-Guided Internal Radiation for Returning Prostate Cancer
This trial tests a new way to use a type of internal radiation (high-dose-rate brachytherapy) guided by MRI to treat prostate cancer that has come back in the same area after previous radiation therapy. It is designed to be more precise and hopefully safer while using the latest PSMA PET scans to make sure the cancer hasn't spread.
Toronto, OntarioAges 18 years+ - NCT06518226Recruiting
Ultra-short radiation with focal boost for prostate cancer
This trial tests a new, shorter course of radiation for intermediate-risk prostate cancer. It aims to give a higher dose to the main tumor while keeping side effects low.
UtrechtAges 18 years+ - NCT06528912Recruiting
Standard Follow-Up Program for Brain Tumor Patients
This trial tests a new follow-up program for people with brain or spinal tumors who are getting radiation therapy. The program aims to improve your care and monitor your recovery after treatment.
GroningenAges 18 years+ - NCT06531681Recruiting
Precision radiotherapy with MRI-guided technology
This trial tests a new type of radiotherapy that uses MRI scans to guide the radiation beam more precisely. It aims to treat tumors while reducing damage to healthy tissue.
HaikouAges 18–75 - NCT06532539RecruitingPhase 2
Cadonilimab with radiation for recurrent endometrial cancer
This trial tests a combined treatment of the immunotherapy drug cadonilimab plus radiation and chemotherapy for endometrial cancer that has come back or spread to only a few places. The goal is to see if this combination can help control the cancer better.
Jinan, ShandongAges 18–80 - NCT06542588RecruitingPhase 2
Short radiation plus chemo and immunotherapy for rectal cancer
This trial tests a combination of short-course radiation, chemotherapy, and two types of immunotherapy (HLX07 and Serplulimab) before surgery for advanced rectal cancer. It aims to see if this approach helps shrink tumors and improve outcomes.
Wuhan, HubeiAges 18–75 - NCT06542757Recruiting
Focused radiation to main prostate tumor using MRI guidance
This trial tests a stronger, more focused radiation dose to the main tumor inside the prostate using MRI guidance. It aims to improve control of intermediate-risk prostate cancer while possibly reducing side effects.
New York, New YorkAges 18 years+ - NCT06545747RecruitingPhase 3
MRI-guided radiation for advanced lung cancer
This trial tests a new way of giving radiation therapy for advanced lung cancer that cannot be surgically removed. It uses MRI scans to guide and adjust the radiation dose, which may help target the tumor more precisely and reduce side effects.
GuangzhouAges 18–75 - NCT06546969RecruitingPhase 1
Combination therapy for advanced bile duct cancer
This trial tests a combination of chemotherapy, immunotherapy, and heat therapy (hyperthermia) with a special radiation technique for advanced bile duct or gallbladder cancer that hasn't been treated before. It aims to see if this combination can help shrink tumors and improve outcomes.
Baltimore, MarylandAges 21 years+ - NCT06551909Recruiting
Radiation plus immunotherapy for glioblastoma patients
This trial tests a combination of radiation and immunotherapy for people with glioblastoma. The goal is to see if adding immunotherapy to standard radiation can improve outcomes.
Milan, MIAges 18–80 - NCT06557343Recruiting
Lung Cell Study After Chest Radiation
This study looks at cells from the lungs of people who developed lung inflammation after chest radiation for cancer. It aims to understand why some people get this reaction, which may help find better treatments.
EdinburghAges 18 years+ - NCT06560697Recruiting
Radiation boost for cervical cancer: SABR vs brachytherapy
This trial compares two types of radiation boost therapy for locally advanced cervical cancer: a newer, precise type called SABR versus the standard brachytherapy. The goal is to see if SABR works as well or better with fewer side effects.

Common questions
- Are there clinical trials for radiotherapy?
- Yes. Clin2 currently lists 1,321 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.
