Recruiting studies
- NCT06208826RecruitingPhase 2
Immunotherapy maintenance after surgery for head and neck cancer
This trial looks at whether continuing immunotherapy can help keep cancer from coming back in people with head and neck cancer who had a good response to chemo-immunotherapy before surgery. You would have already had surgery, and now the study tests a maintenance treatment to strengthen your immune system's fight against any remaining cancer cells.

Comparing chemoimmunotherapy vs chemoradiation for advanced cervical cancer before surgery
This trial tests whether a combination of chemotherapy and immunotherapy (pembrolizumab) before surgery works better than standard chemoradiation for locally advanced cervical cancer. It may help shrink tumors more effectively.
Hefei, AnhuiAges 18–70 - NCT06290505RecruitingPhase 2
Palliative therapy for esophageal cancer
This trial tests a combination of chemotherapy, radiation, and an immunotherapy drug (durvalumab) for esophageal cancer that has spread to a few other places in the body or is too advanced for surgery. It aims to see if this combination helps with swallowing difficulties and slows the cancer's growth.
Garran, Australian Capital TerritoryAges 18 years+ - NCT06297265Recruiting
Gentle breast massage after lumpectomy for breast cancer
This trial studies whether a special gentle massage technique (manual lymphatic drainage) can help women who have had breast-conserving surgery and will receive whole breast radiation. The goal is to see if it reduces side effects and improves recovery.
Los Angeles, CaliforniaAges 18 years+ - NCT06300463RecruitingPhase 2
Immunotherapy combinations for colorectal cancer with liver tumors
This trial tests combinations of immunotherapy drugs for people with colorectal cancer that has spread to the liver and is scheduled for surgery. The goal is to see if these treatments are safe and effective before and after the operation.
New York, New YorkAges 18 years+ - NCT06307327Recruiting
Comparing new and old ways to classify mouth sores from radiation
This study compares a new way of classifying radiation-induced mouth sores (mucositis) with the traditional method. It aims to better understand and manage these painful sores in people receiving radiation for head and neck cancer.
Guangzhou, GuangdongAges 18 years+ - NCT06311968RecruitingPhase 2
Proton radiation after surgery for thymus tumors
This trial tests a type of precise radiation called proton therapy after surgery for thymus tumors. It may help reduce the chance of the tumor coming back while limiting side effects to nearby organs.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT06313203RecruitingPhase 2
Chemotherapy with or without liver-directed treatment for bile duct cancer
This trial tests whether adding a liver-directed treatment (HAI floxuridine or SIRT) to standard chemotherapy (GemOx) is more effective for people with bile duct cancer inside the liver that cannot be removed by surgery. It may be an option for those whose cancer is only in the liver or nearby lymph nodes.
Oslo, OsloAges 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 - NCT06323460RecruitingPhase 2
Less Radiation for HPV Throat Cancer Guided by a Blood Test
This study tests a way to use less radiation for HPV-related throat cancer. Doctors will adjust your treatment based on a simple blood test that tracks cancer DNA, so you may get only the treatment you need.
Columbus, OhioAges 18 years+ - NCT06328686RecruitingEarly Phase 1
Arginine and whole brain radiation for brain metastases
This trial tests whether taking arginine (an amino acid) during whole brain radiation therapy can help people with brain metastases from any type of cancer. It looks at how the treatment affects the body and may improve outcomes.
Atlanta, GeorgiaAges 18 years+ - NCT06333899RecruitingEarly Phase 1
Lorlatinib for newly diagnosed brain tumors with ROS or ALK fusion
This trial tests if lorlatinib, a targeted pill, can shrink or slow the growth of high-grade brain tumors that have a specific ROS or ALK genetic change. It is for children and young adults who have not yet had treatment for their tumor.

Common questions
- Are there clinical trials for radiation?
- Yes. Clin2 currently lists 1,050 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.
