Cadonilimab plus radiation for lung cancer brain mets
This trial tests a combination of a targeted immunotherapy drug (cadonilimab) with a precise type of radiation to treat brain tumors that have grown after initial lung cancer treatment. The goal is to see if this approach can safely shrink brain metastases and improve outcomes.
Changsha, HunanAges 18–75 - NCT06704555RecruitingPhase 2
Radiation plus drug combo for untreated bulky follicular lymphoma
This trial tests a combination of radiation, an immunotherapy drug (tislelizumab), and chemotherapy (RCHOP) for people with previously untreated bulky follicular lymphoma. It aims to see if giving radiation first followed by the drug combo can improve outcomes for larger tumors.
Tianjin, Tianjin MunicipalityAges 18–70 - NCT06704659Recruiting
Repeated radiation for recurrent breast cancer
This study tests giving a second round of radiation therapy to women whose breast cancer has come back in the same breast, at least 3 years after their first radiation. It may be an option for women 55 and older who have a small, local recurrence that can be removed with surgery.
HelsinkiAges 55 years+ - NCT07324577Recruiting
Virtual reality for anxiety during radiation therapy
This study tests whether using a virtual reality (VR) headset during radiation therapy can reduce anxiety. It is for people with prostate, breast, lung, or head and neck cancer who will have at least 15 radiation sessions.
High Point, North CarolinaAges 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.

This trial tests a combination of low-dose radiation, chemotherapy, and immunotherapy for nasopharyngeal cancer that has spread to the liver. It aims to see if this approach can help shrink tumors and improve outcomes.
Changsha, HunanAges 18–70 - NCT07552168RecruitingPhase 2
Advanced Radiation Therapy for Prostate Cancer in Ireland
This trial tests a newer type of radiation therapy called SABR (stereotactic ablative body radiotherapy) for men with prostate cancer. It aims to deliver high doses of radiation precisely to the tumor in fewer treatments, potentially reducing side effects and improving outcomes.
Dublin, LeinsterAges 18 years+ - NCT06709417RecruitingPhase 2
Immunotherapy plus chemo and radiation for advanced esophageal cancer
This trial is testing whether giving a combination of an immunotherapy drug (sintilimab) with chemotherapy, followed by radiation plus more chemotherapy (concurrent chemoradiotherapy), can help people with advanced esophageal cancer that cannot be removed surgically. The goal is to see if this approach shrinks the tumor and improves outcomes.
Shanghai, Shanghai MunicipalityAges 20–75 - NCT06718543RecruitingPhase 2
Short-course radiation with AK112 for rectal cancer before surgery
This trial tests whether combining short-course radiation with an immune therapy drug (AK112) plus chemotherapy before surgery is better than radiation alone for locally advanced rectal cancer. It aims to shrink tumors and improve outcomes without needing stronger treatments later.
Chongqing, Chongqing MunicipalityAges 18–80 - NCT06719700RecruitingPhase 2
Chemo-radiation with two drugs for limited-stage small cell lung cancer
This trial tests combining standard chemotherapy with radiation (chemoradiotherapy) plus two additional drugs, toripalimab and surufatinib, for people with limited-stage small cell lung cancer. The goal is to see if this combination improves outcomes.
Guangzhou, GuangdongAges 18–75 - NCT06727617RecruitingPhase 2
Serplulimab with chemoradiation for high-risk cervical cancer
This trial tests adding an immunotherapy drug (serplulimab) to standard chemoradiation after cervical cancer surgery. It is for patients with at least two high-risk features, like lymph node spread or deep invasion, to see if it helps prevent the cancer from coming back.
Tianjin, Tianjin MunicipalityAges 18–65 - NCT06730308RecruitingPhase 2
Steroids with chemoradiation for thymoma that can't be removed
This trial tests if adding a steroid (methylprednisolone) to standard chemotherapy and radiation helps people with thymoma that cannot be fully removed by surgery or has come back. The goal is to see if this combination works better at controlling the disease.
Guanzhou, GuangdongAges 18–75 - NCT06730295RecruitingPhase 2
Lung cancer radiation trial shrinking target margins
This trial tests a newer, more precise way of giving radiation for lung cancer tumors that are near the center of the chest. The goal is to see if using a smaller treatment area can reduce side effects while still killing the cancer.
Guangzhou, GuangdongAges 18 years+ - NCT06734598RecruitingPhase 4
Botox for Jaw Tightness After Head and Neck Radiation
This study tests whether Botox injections into the jaw muscles can help head and neck cancer survivors who have trouble opening their mouths (trismus) after radiation therapy. If you have tight or painful jaw muscles and limited mouth opening, this treatment may offer relief.
TaipeiAges 18 years+ - NCT06749899RecruitingPhase 3
Immunotherapy with chemoradiation for advanced nasopharyngeal cancer
This trial tests a combination of a new immunotherapy (QL1706) plus standard chemoradiation for people with advanced nasopharyngeal cancer that hasn't spread to distant organs. The goal is to see if adding this drug helps control the cancer better than standard treatment alone.

Common questions
- Are there clinical trials for radiotherapy?
- Yes. Clin2 currently lists 1,317 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.
