Comparing shorter vs. standard radiation for early vocal cord cancer
This study tests if a shorter course of radiation (hypofractionated) works as well as the standard longer course for people with early-stage cancer of the vocal cords. The goal is to find a treatment that is more convenient and has similar results.
Dallas, TexasAges 18 years+ - NCT06084338RecruitingPhase 2
Focused Radiation Therapy Without Hormone Therapy for Advanced Prostate Cancer
This trial tests whether giving focused radiation to many cancer spots (SBRT) can work without using testosterone-blocking hormone therapy. It is for men whose prostate cancer has spread and is no longer responding to low testosterone, and who have already tried one of the newer hormone drugs.

Short course radiation before sarcoma surgery
This trial tests a shorter course of radiation (just 5 days) before surgery for soft tissue sarcoma. The goal is to see if a brief, high-dose radiation schedule works as well as or better than the usual longer course—and may be more convenient for you.
Palo Alto, CaliforniaAges 18 years+ - NCT06101069Recruiting
New MRI scan to tell tumor from radiation damage
This study tests a special MRI technique to better distinguish between tumor regrowth and radiation-related changes in people with brain tumors. If you've had radiation for a brain tumor and now have suspicious changes, this scan might help guide your next steps.
Cleveland, OhioAges 18–60 - NCT06102837Recruiting
Tumor vaccine study for brain surgery patients
This study tests whether a tumor vaccine made from your own surgery tissue can help treat solid tumors, specifically gliomas (brain tumors). It is open to patients having brain surgery at Huashan Hospital, including those with non-tumor conditions like stroke or injury, as long as enough tissue is available.
Shanghai, Shanghai MunicipalityAges Any age - NCT06116019Recruiting
Online adaptive radiotherapy for cancer patients
This trial tests a new radiation therapy machine that adjusts the radiation plan in real-time based on changes in your body. It may help make treatment more precise and reduce side effects.
BerlinAges 18 years+ - NCT06120374Recruiting
Immunotherapy plus radiation after surgery for upper tract cancer
This trial compares combining immunotherapy with radiation versus standard chemotherapy for patients with high-risk upper urinary tract cancer after surgery. It aims to see if the new combination works better at preventing cancer from coming back.
BeijingAges 18 years+ - NCT06122493RecruitingPhase 2
Better treatment for advanced esophageal cancer
This trial tests a new treatment plan for people with advanced esophageal squamous cell carcinoma that has spread to lymph nodes but not to other organs. It aims to find the best way to treat this cancer using radiation and other therapies.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT06123156RecruitingPhase 3
Early erectile rehabilitation after rectal cancer treatment
This trial tests if sildenafil (Viagra) given soon after surgery and radiation for rectal cancer can help preserve erectile function. It is for men with normal erectile function before treatment who have a regular partner.
AmiensAges 18–70 - NCT06138028RecruitingPhase 2/Phase 3
Sintilimab plus chemo and radiation for advanced esophageal cancer
This trial tests a combination of an immunotherapy drug (sintilimab) plus chemotherapy followed by radiation therapy for advanced esophageal cancer that has spread. The goal is to see if this sequence can help shrink tumors and improve outcomes.
Qingdao, ShandongAges 18–80 - NCT06141031RecruitingPhase 1
TTI-101 plus radiation for borderline or locally advanced pancreatic cancer
This trial tests a new oral drug (TTI-101) combined with targeted radiation (SBRT) for people with pancreatic cancer that is not removable by surgery. It aims to see if this combination helps shrink tumors that are borderline resectable or locally advanced.
Aurora, ColoradoAges 18 years+ - NCT06141070RecruitingPhase 3
Adding high-dose radiation to standard treatment for advanced lung cancer
This trial tests whether adding a high, focused dose of radiation to the usual first treatment (chemo and/or immunotherapy) can help people with non-small cell lung cancer that has spread to a limited number of spots (up to 5). The goal is to see if this approach improves how well the treatment works.

Study of retifanlimab, bevacizumab, and radiation for recurrent glioblastoma
This trial tests a combination of immunotherapy (retifanlimab), a targeted drug (bevacizumab), and low-dose radiation for people whose glioblastoma has come back. The goal is to see if this treatment can help shrink or slow the tumor.
Scottsdale, ArizonaAges 18 years+ - NCT06162650RecruitingPhase 2
Pre-surgery chemo-radiation therapy for rectal cancer
This trial tests a combination of chemotherapy and radiation therapy before surgery for people with mid or low rectal cancer that hasn't spread. The goal is to see if this approach works better than current treatments.

Common questions
- Are there clinical trials for radiotherapy?
- Yes. Clin2 currently lists 1,312 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.
