Radiation, immunotherapy and targeted therapy for early-stage lung cancer
This trial tests a combination of radiation therapy before surgery, followed by the immunotherapy drug tislelizumab and the targeted therapy drug anlotinib after surgery, for people with stage II to IIIA non-small cell lung cancer (NSCLC). The goal is to see if this approach can improve outcomes for patients whose tumors can be removed surgically.

This trial tests whether radiation therapy can be personalized based on your risk of the cancer coming back and your risk of side effects from radiation. Depending on those factors, you may receive a tailored radiation plan that could be more or less intense.
MontpellierAges 18 years+ - NCT06385717Recruiting
ESD plus chemoradiotherapy for early esophageal cancer
This study tests whether combining radiation and chemotherapy after endoscopic removal of early-stage esophageal cancer can effectively treat the cancer without needing surgery. It may be an option for people whose cancer was removed with ESD but who want to avoid additional surgery.
Hangzhou, ZhejiangAges 18–75 - NCT06389201Recruiting

Radiation for Graves' Eye Disease: 1 vs 2 Weeks
This trial tests if a shorter course of radiation (1 week) works as well as a standard longer course (2 weeks) for treating active thyroid eye disease that did not improve enough with steroid medicine. It may be an option if you still have eye symptoms after steroid treatment.
Bangkok NoiAges 18–70 - NCT06397560Recruiting
Proton radiation for returning brain tumors
This trial tests a new type of proton radiation therapy given at a lower dose rate to treat brain tumors that have come back after previous radiation. The goal is to see if it's safe and effective.
Boca Raton, FloridaAges 18 years+ - NCT06402708RecruitingPhase 3
Chemotherapy after surgery for thymic cancer
This trial tests whether additional chemotherapy after surgery can help prevent thymic cancer from coming back. It is for people who have had their thymus tumor completely removed and are in good health.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06408584Recruiting
Short radiation plus two drugs for returning esophageal cancer
This trial tests a short course of radiation combined with two drugs (raltitrexed and tislelizumab) for people with esophageal cancer that has returned after standard treatment. The goal is to see if these combinations can shrink tumors and improve survival.
HefeiAges 18 years+ - NCT06416007RecruitingPhase 2
Lattice radiation for large tumor palliation
This study tests a new way to deliver radiation called lattice therapy for people with large solid tumors that are causing symptoms. It aims to give a stronger radiation dose to help shrink the tumor and relieve discomfort.
Cincinnati, OhioAges 18 years+ - NCT06428045RecruitingPhase 1
STARLITE for hard-to-surgery high-grade brain tumors
This trial tests a new treatment called STARLITE for people with fast-growing brain tumors (high-grade gliomas) that cannot be safely removed with surgery. The treatment uses a laser to destroy the tumor from the inside. It may be a good option if you haven't had any prior treatment for this tumor.
Miami, FloridaAges 18 years+ - NCT06444776Recruiting
Taste and saliva changes during radiotherapy for head & neck cancer
This study looks at how radiation therapy for head and neck cancer changes your sense of taste and saliva. It aims to better understand and manage these side effects.
Aarau, Canton of AargauAges 18 years+ - NCT06446726RecruitingPhase 2
Low-dose radiation, chemo, and immunotherapy before esophageal cancer surgery
This trial tests a combination of low-dose radiation, chemotherapy, and immunotherapy before surgery for esophageal cancer. The goal is to see if this approach helps shrink the tumor and improve outcomes.
Chengdu, SichuanAges 18–75 - NCT06455124RecruitingPhase 2
Short radiation and chemo-immunotherapy for early rectal cancer after local surgery
This trial tests a combination of short-course radiation, chemotherapy (CapeOx), and an immunotherapy drug (PD-1 inhibitor) for people with early-stage rectal cancer who have had a local excision but are at high risk of the cancer coming back. The goal is to avoid more extensive surgery while still effectively treating the cancer.
ShanghaiAges 18–75 - NCT06457906RecruitingPhase 3
Focused radiation vs whole brain radiation for up to 10 lung cancer brain spots
This trial compares two types of radiation for people with small cell lung cancer that has spread to the brain (10 or fewer spots). One approach uses focused radiation only on the tumors, the other treats the whole brain while trying to protect memory. The goal is to see which works better with fewer side effects.
Beijing, Beijing MunicipalityAges 18–80 - NCT06462378RecruitingPhase 2
Proton therapy for advanced cervical cancer
This trial tests whether a precise type of radiation called proton therapy can work well for cervical cancer that has spread to lymph nodes. It aims to see if this treatment can shrink tumors with fewer side effects.
CopenhagenAges 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

Common questions
- Are there clinical trials for radiotherapy?
- Yes. Clin2 currently lists 1,324 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.
