BeijingAges 18 years+ - NCT06999148Enrolling by invitationPhase 2
Testing sonodynamic therapy with radiation and chemo for brainstem glioma
This trial tests whether adding sonodynamic therapy (a treatment that uses sound waves to activate a drug) before standard radiation and chemotherapy can help people with a type of brainstem glioma called DIPG. The goal is to see if this combination improves survival.
Zhengzhou, UndefinedAges Up to 75 years - NCT06987370Recruiting
Radiation study for bone metastases with soft tissue mass
This trial tests a new way of giving radiation (SFRT and SCART) to bone metastases that have a soft tissue mass. It may be an option if you have limited spread and your organs are working well.
Jinan, ShandongAges 18–75 - NCT04847284Recruiting
Radiation during brain tumor surgery for brain metastases
This trial tests giving targeted radiation while surgeons are operating to treat brain metastases. It may help control the cancer locally at the time of surgery, especially for certain single lesions.

HIMARS: Stereotactic radiation for prostate cancer spread
This trial tests adding targeted radiation (SRT) to bone or lymph node metastases in men with prostate cancer that has continued to grow despite hormone therapy, chemo, or other treatments. The goal is to see if radiation can help control the disease and improve outcomes.
Saint-HerblainAges 18 years+ - NCT06183983Recruiting
Advanced MRI for better glioblastoma radiation
This trial tests whether using advanced MRI scans before radiation therapy can help doctors target the tumor more precisely and possibly improve outcomes for people with glioblastoma. It aims to make radiation treatment more personalized.
Rotterdam, South HollandAges 18 years+ - NCT04952480RecruitingPhase 2
Adaptive chest radiation for newly diagnosed small cell lung cancer
This study tests a customized (“adaptive”) way to give radiation to the chest for newly diagnosed small cell lung cancer. It aims to improve how well treatment targets the tumor while safely adjusting to tumor changes during therapy.
Edmonton, AlbertaAges 18 years+ - NCT06950073Recruiting
Second radiation treatment for lung cancer in the chest
This study tests whether giving a second course of radiation to the chest (called retreatment) can control lung cancer that has come back or a new cancer that started there. People who have already had radiation to their chest and are healthy enough for more may be eligible.
Aarhus, JutlandAges Any age - NCT06949111RecruitingPhase 2
Combining radiation and chemo to make colon cancer removable
This trial tests whether giving radiation therapy along with standard chemotherapy before surgery can help shrink advanced colon cancer that has grown through the bowel wall but hasn't spread to other organs. It is for a specific type of colon cancer called pMMR/MSS.
Shijiazhuang, HebeiAges 18 years+ - NCT05413473RecruitingPhase 1/Phase 2
Testing image-guided radiotherapy using MRI scans
This trial studies a way of planning and delivering radiation using MRI pictures to help target tumors more accurately. It may benefit people by improving how radiation is aligned, and it’s being tested for safety and effectiveness compared with the usual CT-based planning.
Edmonton, AlbertaAges 18 years+ - NCT06384053Recruiting
Heat plus radiation for skin cancer in older adults
This trial tests whether adding heat therapy (hyperthermia) to radiation therapy works well for older adults with larger non-melanoma skin cancers. It may help shrink tumors without needing surgery.
Aarau, Canton of AargauAges 65 years+ - NCT06205927RecruitingPhase 2
Carbon Ion Boost for Advanced Lung Cancer
This trial tests a new way to give radiation therapy (carbon ion boost) to people with advanced, inoperable lung cancer. The goal is to see if targeting the most aggressive parts of the tumor with a higher dose can improve outcomes.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT06911684RecruitingPhase 2
Combination therapy before surgery for rectal cancer
This trial tests a combination of radiation, two immunotherapy drugs (iparomlimab and tuvonralimab), a targeted therapy (regorafenib), and chemotherapy (CAPOX) given before surgery for locally advanced rectal cancer. The goal is to see if this approach can shrink the tumor and improve outcomes for people whose tumors have normal mismatch repair proteins (pMMR/MSS).
Guangzhou, GuangdongAges 18–75 - NCT06360653Recruiting
Stereotactic radiation after surgery for endometrial cancer
This trial tests a precise type of radiation (stereotactic radiotherapy) given after surgery for endometrial cancer. It aims to improve treatment while reducing side effects.
PalermoAges 18–80 - NCT06903312RecruitingPhase 4
Removing the main kidney tumor during immunotherapy for advanced kidney cancer
This trial tests whether removing or burning (ablating) the main kidney tumor helps people with advanced kidney cancer who are already doing well on immunotherapy. Researchers want to see if combining local treatment with ongoing immunotherapy can improve outcomes.
RomaAges 18 years+ - NCT06908668RecruitingPhase 2
Adebrelimab plus chemo with or without radiation before breast cancer surgery
This trial tests adding a drug called adebrelimab to standard chemotherapy and possibly radiation, given before surgery for breast cancer that is HER2-negative and locally advanced. The goal is to see if this combination helps shrink tumors more effectively, potentially allowing for breast-conserving surgery.
BeijingAges 18–70 - NCT04242589RecruitingPhase 2
Radiation plus bone cement for painful spinal metastasis pain
This trial tests adding a bone-cement procedure (vertebroplasty) along with radiation to reduce pain from cancer that has spread to the spine. It is for adults with painful metastatic (spread) tumors in the middle or lower spine, without current spinal cord pressure.
Edmonton, AlbertaAges 18 years+ - NCT05150145Recruiting
Radiation versus observation for liver spread of small cell lung cancer
This trial compares giving liver-directed radiation to watching closely without radiation. It is for people with small cell lung cancer that has spread to the liver, to see whether radiation helps control the disease.
Guiyang, GuizhouAges 18–70 - NCT06890871Enrolling by invitationPhase 1/Phase 2
Radiation with immunotherapy and anti-angiogenic therapy for advanced HER2-negative breast cancer
This trial tests a combination of radiation therapy, immunotherapy, and a drug that blocks blood vessel growth for advanced HER2-negative breast cancer that has spread. It is for patients whose cancer has worsened after at least two prior treatments.
Wuhan, HubeiAges 18–75 - NCT06887829Recruiting
A study of low-dose radiation for knee osteoarthritis
This study tests a low-dose radiation treatment for knee osteoarthritis that might reduce pain and improve knee function. If you have been dealing with constant or intermittent knee pain and meet the other criteria, this could be an option for you.
Rochester, MinnesotaAges 50–100 - NCT06686459Recruiting

Radiation after chemo-immunotherapy and surgery for stage III lung cancer
This trial is testing whether giving radiation therapy after surgery can help prevent lung cancer from coming back in people who have already had chemotherapy and immunotherapy before surgery. It is for patients whose cancer had spread to chest lymph nodes and who still have some cancer left in those nodes after surgery.
Montreal, QuebecAges 18 years+ - NCT06865339RecruitingPhase 2

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.
