Recruiting studies
- NCT04340024Recruiting
Testing blood markers linked to how well radiation works
This study looks for “biomarkers,” or measurable signs (often from blood or samples), that may show which cancers respond better to radiation therapy. It may help doctors choose radiation treatment more precisely, especially for people who had significant side effects before.
SingaporeAges 21–99 - NCT06966388RecruitingPhase 1
Azelaic acid cream for breast cancer patients during radiation
This study tests whether using a topical azelaic acid cream twice daily during radiation therapy is feasible for breast cancer patients. The cream may help reduce skin side effects from radiation, and the study focuses on people with certain skin types that tan easily or have more pigment.
Richmond, VirginiaAges 18 years+ - NCT06205485RecruitingPhase 3
Chemotherapy and surgery vs chemoradiation for rectal cancer
This trial compares two approaches for early-stage rectal cancer: chemotherapy plus local surgery versus standard chemoradiotherapy. It aims to see if less intensive treatment can work just as well, reducing side effects.
Phoenix, ArizonaAges 18 years+ - NCT04033497Recruiting
MRI study to tell tumor from dead tissue after brain radiation
This study uses MRI scans to figure out whether an enlarging spot in the brain after stereotactic (focused) radiation is still living tumor or dead tissue. It may help doctors better understand what’s happening after radiation and guide next treatment decisions.
Boston, MassachusettsAges 18 years+ - NCT04060706Recruiting
Testing new computer tools for radiation treatment planning
This study tests how well new computer methods (called algorithms and machine learning) can support radiation therapy decisions. You might benefit by helping improve how radiation is planned and checked, especially for cancers treated with curative-intent therapy.
Cambridge, CambridgeshireAges 18 years+ - NCT04069884Recruiting
Avoid extra lymph-node radiation for certain node-positive breast cancers
This trial tests a way to decide whether you can safely receive less radiation to lymph nodes after surgery for breast cancer that has spread to nearby nodes. If you qualify as “low risk,” the goal is to reduce radiation exposure while keeping cancer control safe.
Guangzhou, GuangdongAges 18–70 - NCT04080492Recruiting
Quality of life study for heart disease patients
This study asks people with certain heart conditions to complete follow-up questionnaires to better understand how their quality of life changes over time. It may help improve how care plans are made and supported for patients and their families.
Cleveland, OhioAges 18–70 - NCT04082520RecruitingPhase 2
Lutathera for non-surgery meningioma that keeps growing
This Phase 2 study tests Lutathera to treat meningioma that cannot be safely removed with surgery and is still growing after radiation. It uses a special scan to make sure the tumor has the right target, and aims to improve tumor control and safety.
Rochester, MinnesotaAges 18 years+ - NCT04083937Recruiting
Radiation after prostate surgery for men with prostate cancer
This study looks at different radiation approaches after prostate surgery to see which strategy works best. You may be able to join if your cancer is at a stage where radiation to the prostate bed is planned, and you have not had prior radiation.
HeidelbergAges 18 years+ - NCT04084730RecruitingPhase 2
3-day radiation after breast-conserving surgery for certain breast cancers
This trial tests whether a shorter, 3-day course of partial breast radiation after surgery works as well as standard radiation for women with early-stage breast cancer. It may help reduce time in treatment while aiming to keep cancer from coming back in the treated breast area.
Norwalk, ConnecticutAges 45 years+ - NCT04097067Recruiting
Radiation therapy for slow-growing stomach lymphoma
This study tests whether a specific course of focused radiation (20 Gy) can control indolent (slow-growing) lymphoma in the stomach or upper small intestine. It may help shrink or stabilize tumors and lymph node involvement while limiting side effects.
Münster, North Rhine-WestphaliaAges 18 years+ - NCT04104945Recruiting
Trial to reduce radiation fields in p16+ oropharyngeal cancer
This study tests whether shrinking the “planned radiation area” (elective treatment volumes) can still treat p16-positive oropharyngeal cancer effectively. It may help reduce unnecessary radiation to nearby healthy tissues while keeping the cancer treatment curative.
Calgary, AlbertaAges 18 years+ - NCT04115254Recruiting
MRI-guided focused radiation for certain tumors
This study tests a type of high-precision radiation guided by MRI pictures to treat certain cancers. It may help doctors deliver radiation more accurately while avoiding nearby healthy tissue, but you must be able to safely complete an MRI scan and meet tumor-size and health requirements.
Boston, MassachusettsAges 18 years+ - NCT04122313Recruiting
Radiation after surgery for Dupuytren’s hand contracture
This trial looks at using radiation after contracture-release surgery for people with Dupuytren’s disease. It may help prevent the hand tightening from coming back and improve hand function.
Minneapolis, MinnesotaAges 18 years+ - NCT04151082RecruitingPhase 1/Phase 2
Steroid therapy for late nerve damage after throat cancer radiation
This trial tests whether high-dose steroids (prednisone or methylprednisolone) can improve symptoms of nerve damage that may occur years after radiation treatment for oropharyngeal cancer. It includes a registry for tracking similar nerve issues in head and neck cancer survivors.
Houston, TexasAges 18 years+ - NCT04165772RecruitingPhase 2
Dostarlimab for locally advanced mismatch-repair deficient solid tumors
This Phase 2 trial studies dostarlimab (an immune therapy that targets PD-1) given before surgery or other initial treatment. It aims to shrink certain locally advanced cancers that have mismatch repair deficiency, potentially making treatment easier and improving outcomes.
Hartford, ConnecticutAges 18 years+ - NCT04181684Recruiting
Laser surgery plus targeted radiation for recurrent brain gliomas
This trial studies whether a special laser procedure (LITT) followed by focused, reduced-dose radiation can control glioma tumors that have come back. It may help people with recurrent brain tumors avoid or delay more extensive treatment.
Baltimore, MarylandAges 22 years+ - NCT04188535Recruiting
MRI scans during radiation treatment
This study does repeated MRI (detailed brain/body imaging) while you receive radiation therapy. It aims to see how these serial scans relate to treatment and outcomes, which could help improve care planning for different cancers.
Boston, MassachusettsAges 18 years+ - NCT04220749RecruitingPhase 2
Radiation vs mouth surgery for HPV-negative throat cancer
This Phase 2 trial compares two standard cancer treatments—radiation or surgery through the mouth—for HPV-negative oropharyngeal throat cancer. It aims to find out which approach works better while keeping side effects and quality of life acceptable.
London, OntarioAges 18 years+ - NCT04249154RecruitingPhase 2
After prostate surgery, test radiation plus hormone shots
This trial studies whether giving a shorter-course radiation plan after prostate surgery, along with hormone shots (LHRH), can improve outcomes for people with higher-risk prostate cancer. You may be eligible if your PSA (a blood marker) is either still low but high-risk by pathology, or it has started to rise again after surgery.
Montreal, QuebecAges 18 years+ - NCT04265430RecruitingPhase 4
MRI scans to predict normal-tissue side effects after treatment
This trial uses repeated MRI scans to better predict which patients may develop painful jaw and mouth tissue problems after radiation and/or certain bone or blood-vessel medicines. It may help clinicians spot problems earlier and tailor follow-up care.
Houston, TexasAges 18 years+ - NCT04266223Recruiting
Head and neck mask monitoring during radiation to improve setup
This trial tests a surface-monitoring technology that checks a head-and-neck radiation “positioning mask” during treatment. It may help the radiation team make sure the mask and patient are aligned correctly for safer, more accurate therapy.
Blacktown, New South WalesAges 18 years+ - NCT04368702Recruiting
MRI-guided radiation for people needing radiation for cancer
This study tests whether radiation given with help from MRI (a type of scan) can better treat cancers that need radiation. You may be eligible if your cancer is confirmed and you can safely have MRI scans.
Boston, MassachusettsAges 18 years+ - NCT04373720Recruiting
MRI scan to tell scar from tumor in treated brain glioma
This study uses an advanced MRI scan to help doctors tell the difference between radiation scar (radiation necrosis) and returning glioma (recurrent glioma) after prior treatment. It may help guide the next steps for care if you have a new or changing brain lesion.
