Recruiting studies
- NCT06341595RecruitingPhase 2
Chemo, radiation and immunotherapy before surgery for stomach cancer with PALM

This study tests a special low-radiation CT scan with a contrast dye called Iomeron 400 to see if it works well for checking lung nodules or pneumonia.
ZurichAges 18 years+ - NCT04603209Recruiting
Check-in registry for radiation during breast-conserving surgery
This registry study tracks people with early-stage, single-area breast cancer to understand outcomes when radiation is given during breast-conserving surgery. It may help doctors improve treatment planning for patients like you.
Santa Monica, CaliforniaAges 18 years+ - NCT06356779Recruiting
Studying local treatment for a few cancer spots
This study is for people with solid tumors that have spread to a few spots (5 or fewer) in the body. It tests whether using a focused treatment like radiation or ablation on those spots can help control the cancer long-term.
Copenhagen, Capital Region of DenmarkAges 18 years+ - NCT05228431RecruitingPhase 2
Tested treatment plan for locally advanced rectal cancer
This Phase 2 study looks at a modified “sandwich” treatment sequence for people with locally advanced rectal cancer—aiming to control the cancer before and after surgery. It may help you if you’re eligible and can follow the study’s treatment and safety requirements.
Guangzhou, GuangdongAges 18–75 - 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 - NCT04444869RecruitingPhase 2
Lower-dose radiation with chemotherapy for low-risk HPV throat cancer
This trial tests whether a less intense (lower-dose) radiation plan, combined with chemotherapy, can control HPV-positive oropharyngeal (throat) cancer with fewer side effects. It targets people considered “low-risk” based on tumor size and lymph node involvement.
Columbia, MissouriAges 18 years+ - NCT06323369RecruitingPhase 2
Tislelizumab plus chemo before surgery vs surgery alone for head and neck cancer
This trial tests whether giving tislelizumab (an immunotherapy) with chemotherapy before surgery works better than surgery alone for people with head and neck cancer that has not spread to lymph nodes. It's for cancers that can be removed with surgery, and the goal is to see if the pre-surgery treatment improves outcomes.
Guangzhou, YuexiuAges 18–75 - NCT05582265RecruitingPhase 3
Study immune drug plus chemo before surgery versus surgery first
This Phase 3 trial compares two treatment plans for stage III/IVA head and neck squamous cell cancer (HNSCC). One plan uses an immune drug with chemotherapy before surgery; the other goes straight to surgery first, to see which approach works better.
Guanzhou, GuangdongAges 18–80 - NCT03604627Recruiting
Checking coronary calcium to study late heart blood vessel changes
This study looks at coronary calcium (a signal seen on heart scans) to help measure early or late heart blood-vessel problems in people who had cancer treatment as children or young adults. The goal is to better understand who may be at higher risk years later, especially after radiation or certain chemotherapy.
Villejuif, Val De MarneAges 18 years+ - NCT07845929Recruiting
AI help for clearer low-dose CT images
This study tests an artificial intelligence model that helps create clearer images from a lower-dose CT scan, which could mean less radiation exposure during your procedure. It aims to improve image quality while keeping radiation doses as low as possible.
Hefei, AnhuiAges 18 years+ - NCT07849088RecruitingPhase 2
Chinese herbal medicine to protect kidneys during radiation therapy
This study tests a traditional Chinese herbal medicine (called Zhixiao Tongmai Ning) to see if it can protect your kidneys from damage caused by radiation therapy. If you have kidney cancer and are receiving radiation, this treatment might help keep your healthy kidney tissue working better.
Beijing, Beijing MunicipalityAges 18 years+ - 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 - NCT07838519Enrolling by invitation
Personalized lung cancer screening for veterans
This study tests a personalized approach to help veterans decide if lung cancer screening is right for them. It aims to improve early detection by considering each person's unique risk factors, such as smoking history, military exposures, and lung health.
Aurora, ColoradoAges 50–80 - 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 - NCT06110572RecruitingPhase 1/Phase 2
Total body irradiation with immunotherapy for extensive SCLC
This trial adds total body irradiation (a low dose of radiation to the whole body) to standard atezolizumab (immunotherapy) plus chemotherapy for people with extensive-stage small cell lung cancer. The goal is to see if the radiation helps the immunotherapy work better.
Nashville, TennesseeAges 18 years+ - NCT06461793RecruitingPhase 2
Higher dose radiation with hormone therapy for high-risk prostate cancer
This trial tests a higher dose of radiation given in fewer sessions (hypofractionated) combined with hormone therapy for men with high-risk prostate cancer that has not spread. A gel spacer called SpaceOAR is used to protect the rectum. The goal is to see if this approach is safe and effective.
SeoulAges 20 years+ - NCT06461819RecruitingPhase 2
Higher radiation dose for low-to-intermediate prostate cancer
This trial tests if giving a higher dose of radiation in fewer sessions, while using SpaceOAR to protect the rectum, is safe for men with low-to-intermediate risk prostate cancer that hasn't spread.
SeoulAges 20 years+ - NCT07830394Recruiting

Common questions
- Are there clinical trials for radiation?
- Yes. Clin2 currently lists 1,030 recruiting radiation 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 radiation 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 radiation 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.
