Recruiting studies
- NCT06247163Recruiting

New drug combo for untreated colon cancer with liver spread
This trial tests a new combination of drugs (Retlirafusp Alfa, Bevacizumab, and chemotherapy) with or without a short course of radiation for people with colorectal cancer that has spread only to the liver and who have not had any prior treatment. The goal is to see if this approach is safe and effective.
Wuhan, HubeiAges 18–75 - NCT07715188Recruiting
Low dose radiation for osteoarthritis
This trial tests if a very low dose of radiation can help relieve pain from osteoarthritis in joints like hips, knees, hands, shoulders, ankles, or elbows. It is for people whose pain has not improved with standard treatments or who want to try a gentler option before considering surgery.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07717268RecruitingPhase 2
Stereotactic Radiation Plus New Hormone Therapy for Prostate Cancer
This trial tests a targeted, high-dose radiation therapy (SBRT) plus a newer hormone drug (abiraterone or enzalutamide) for men whose prostate cancer has spread to a small number of spots (5 or fewer) and is no longer controlled by standard hormone therapy.
Zaragoza, AragonAges Any age - NCT07711847Recruiting
Prone positioning for faster breast radiation therapy
This trial tests a personalized prone-immobilization device for partial breast radiation after surgery. It aims to make treatment more comfortable and accurate for patients who have had breast-conserving surgery.
New York, New YorkAges 40 years+ - NCT07707648RecruitingEarly Phase 1
Testing ENCER for fatigue during chemo or radiation
This trial tests if ENCER can safely help with cancer-related fatigue. You can join if you're starting a new round of chemo or radiation and can use a smartwatch and answer digital surveys.
Tel AvivAges 18 years+ - NCT06637345Recruiting
Mesothelioma radiotherapy side effect study (MESORTIBO)
This study looks for markers in the blood that can predict side effects in patients with pleural mesothelioma who receive high-dose radiation. If you've had chemotherapy and are getting or have gotten high-dose radiation to the whole chest, researchers want to see if they can identify who is at higher risk of side effects.
Aviano, PordenoneAges 18 years+ - NCT06274892Recruiting
Using an app to improve radiotherapy check-ins
This study tests whether using a mobile app to report symptoms during radiation treatment helps doctors better support patients. It is for people with breast or prostate cancer starting radiation therapy at Princess Margaret Cancer Centre.
Toronto, OntarioAges 18 years+ - NCT07703033Recruiting
Heart Impact Study for Breast Cancer Radiotherapy
This study looks at how information about the heart may affect treatment decisions for people receiving radiation therapy for breast cancer. It aims to help reduce heart-related side effects from treatment.
CopenhagenAges 35 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 - NCT07692152RecruitingPhase 3
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 - NCT07689851RecruitingPhase 2
Chemoradiotherapy plus an immunotherapy for advanced gastric cancer
This trial studies a new immunotherapy drug (SHR-1701) combined with standard chemoradiotherapy for people with advanced stomach or esophagus cancer that cannot be surgically removed. The goal is to see if adding this immune treatment helps control the tumor better than standard treatments alone.
Shenzhen, GuangdongAges 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+ - NCT07690618RecruitingPhase 1
Heat therapy for head and neck cancer
This phase 1 trial tests adding heat therapy (thermotherapy) to standard radiation (with or without chemo) for head and neck cancer. It aims to see if it is safe and effective for patients with locally advanced disease who have not had radiation before.
Rotterdam, South HollandAges 18 years+ - NCT03788213Recruiting
Shorter vs longer radiation after breast cancer surgery
This trial compares giving breast radiation over one week versus three weeks after surgery. It aims to see whether the shorter schedule works just as well and is safe for people with certain types of early breast cancer.
Kolkata, West BengalAges 18 years+ - NCT07687147Recruiting
Daily adjusted radiation dose for abdominal and pelvic tumors
This trial tests a new way to give radiation therapy for tumors in the belly or pelvis. Doctors will use daily MRI scans to adjust the radiation dose, aiming to better protect nearby organs while still treating the cancer.

Arabic quality of life measure for head and neck cancer patients

Tislelizumab after lung cancer chemotherapy and radiation
This Phase 2 study tests tislelizumab (an immune medicine) given after chemotherapy and radiation for stage III non-small cell lung cancer that has not been treated before. It may help improve how well the cancer responds and how long patients can stay in remission, with or without an added medication called bevacizumab.
GuangzhouAges 18–75 - NCT07669493Recruiting

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.
