Recruiting studies
- NCT05786742Recruiting
Radiation plan test for early prostate cancer with a boost
This trial tests a more concentrated radiation schedule for early-stage prostate cancer, using an extra high-dose “boost” delivered from inside the body. It may help by treating the prostate more precisely while aiming to keep side effects manageable.
QuébecAges 18–95 - NCT06492486RecruitingPhase 2
Brain tumor radiation study using AI planning
This trial tests a new way to plan radiation therapy for brain tumors (gliomas) using artificial intelligence. It aims to make treatment more precise and personalized for people with either aggressive (GBM) or slower-growing (IDH-mutant) gliomas.
Mumbai, MaharatshtraAges 18–70 - NCT06487403Recruiting
Delaying radiation for head and neck cancer: MRI and immune markers study
This study tests whether delaying radiation therapy can help doctors learn more from MRI scans and immune system changes in patients with head and neck cancer. This could lead to better treatment decisions.
Toronto, OntarioAges 18 years+ - NCT06356584RecruitingPhase 2
A drug combination with or without radiation for advanced colorectal cancer
This trial tests a new drug combo (fruquintinib and sintilimab) with or without radiation for people with colorectal cancer that has spread to the liver and has not responded to earlier treatments.
Jinan, ShandongAges 18–75 - NCT06297902Recruiting
PET-guided Radiation for Head and Neck Cancer
This trial tests a new way to give radiation therapy for head and neck cancer. By using a special PET scan to guide where higher radiation doses are given, doctors hope to improve treatment while reducing side effects. It is for people whose cancer is not early-stage and who will receive standard radiation therapy.
BergenAges 18 years+ - NCT05895344Recruiting
Compare proton vs modern radiation effects on thinking
This study compares two types of radiation—proton therapy versus modern fractionated radiation—to see how they affect long-term thinking (cognitive function) and daily abilities in people with a specific skull-base tumor. It may help clarify which radiation approach best protects brain and nerve function over time.
CaenAges 18–70 - NCT05561634RecruitingPhase 2
Test targeted medicine with radiation for advanced skin cancer
This Phase 2 study looks at using a medication that blocks the “Sonic Hedgehog” pathway together with radiotherapy to reduce future problems from locally advanced basal cell carcinoma (BCC). It’s for people whose cancer responded completely to the first Sonic Hedgehog pathway inhibitor treatment and where doctors can confirm that response with a tissue test.
LilleAges 18 years+ - NCT06239727RecruitingPhase 3
Reduced-dose radiotherapy for stage III nasopharyngeal cancer based on response
This trial tests whether a lower dose of radiation can safely treat stage III nasopharyngeal cancer if you have already responded well to initial chemotherapy plus immunotherapy (Camrelizumab). The goal is to reduce side effects while still controlling the cancer.
Fuzhou, FujianAges 18–65 - NCT06069830Recruiting
PET scan and EBV test guided treatment for nasal NK/T cell lymphoma
This trial uses PET scans and EBV DNA levels to personalize treatment for patients with early-stage nasal NK/T cell lymphoma. It aims to reduce side effects by adjusting therapy based on how well the cancer responds.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05943119RecruitingPhase 2
Radiation planning after sinus surgery using dose painting
This trial tests a specialized way of planning radiation (“dose painting”) for people with cancer of the sinuses after they’ve had endoscopic surgery. It may help deliver the right radiation dose to different tumor areas while sparing nearby normal tissues.
CaenAges 18 years+ - NCT05929222RecruitingPhase 3
Radiation with or without an antibody for early follicular lymphoma
This study tests whether adding obinutuzumab (an antibody medicine) to local radiation works better than radiation alone in early-stage follicular lymphoma. It aims to improve disease control while keeping treatment safe.
Sassuolo, Modena (MO)Ages 18 years+ - NCT05893381RecruitingPhase 2
Targeted PSMA scan plus focused radiation vs radiation alone
This trial tests whether adding a PSMA-targeted radioactive medicine (Lu-PSMA) to focused stereotactic radiation to a few prostate cancer spots works better than radiation alone. It may help people with limited, asymptomatic spread of prostate cancer by improving cancer control while carefully monitoring side effects.
Cesena, FCAges 18 years+ - NCT05717166RecruitingPhase 3
Stereotactic radiation for limited metastases with a main tumor
This trial tests whether a precise type of radiation can control cancer that has spread to a limited number of sites (1–10) while you also have the main tumor. It aims to improve outcomes by treating all visible cancer spots with stereotactic ablative radiotherapy.
Prince George, British ColumbiaAges 18 years+ - NCT05514327Recruiting
Radiation plus CAR-T for relapsed lymphoma after chemo
This study tests an “ultra-fraction” radiation treatment given before CAR-T therapy to help control aggressive lymphoma that has come back or did not respond. It may help some people bridge (bridge = hold the disease stable) while they wait for CAR-T to work.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05412225RecruitingPhase 1
Pre-surgery radiation, then mastectomy and immediate breast reconstruction
This Phase 1 study looks at giving radiation before surgery for people with locally advanced breast cancer, then performing a mastectomy and immediate reconstruction. It aims to see whether this combined approach can shrink the cancer before surgery and safely allow reconstruction afterward.
Basking Ridge, New JerseyAges 18 years+ - NCT05027711RecruitingPhase 2
MRI-guided precise radiation for liver metastases
This Phase 2 trial tests an MRI-guided, highly targeted radiation treatment (SBRT) for tumors that have spread to the liver. It may help shrink 1–3 liver metastases while using imaging to better guide treatment.
HeidelbergAges 18 years+ - NCT04983095Recruiting
Targeted radiation for a few prostate cancer metastases
This trial looks at whether a precise form of radiation (stereotactic body radiotherapy) can control a small number of prostate cancer spots seen on a special scan (PSMA PET/CT). It may help by treating limited metastases while avoiding unnecessary treatment elsewhere.
Lund, LundAges 18 years+ - NCT04299646RecruitingPhase 2
Stereotactic radiation for limited spread in kidney cancer
This trial tests whether targeted, high-precision radiation (stereotactic radiotherapy) can control a small number of growing kidney cancer metastases while you continue systemic treatment. It may help people who have “oligoprogressive” disease, where only 1–3 spots are getting worse.
AlbiAges 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+ - NCT04115267Recruiting
Registry study tracking side effects from radiation and medicines
This study follows people with cancer to better understand which treatments cause certain side effects when radiation is combined with targeted (molecular) medicines. Your participation may help doctors predict and manage side effects more safely in the future.
Montreal, QuebecAges 18 years+ - NCT07777614RecruitingPhase 2
Higher-dose lung radiation for early-stage lung cancer or a single lung tumor
This trial tests a higher-dose radiation treatment for lung cancer or a single tumor in the lung. It is designed for people who cannot have surgery or prefer not to, and whose tumor is near the chest wall making standard radiation difficult.
DublinAges 18 years+ - NCT07448142RecruitingPhase 2
Low-dose radiation with immunotherapy and chemo for advanced rectal cancer
This trial tests a combination of low-dose radiation, an immunotherapy drug called pucotenlimab, and chemotherapy for locally advanced rectal cancer that has not spread. The goal is to see if adding radiation helps shrink the tumor more effectively before surgery.
Guangzhou, GuanggongAges 18–75 - NCT02797366RecruitingPhase 2
Proton beam radiation for adult brain and spine tumors
This trial studies whether proton radiotherapy can treat primary brain (and sometimes spine) tumors in adults. You may join because your tumor type and situation fit specific diagnoses, including some cases needing a re-treatment plan.
GothenburgAges 18 years+ - NCT04172753Recruiting
Online MRI-guided radiation therapy on a 1.5T machine
This trial checks whether it’s practical and safe to deliver radiation treatment using real-time MRI guidance, with the process supported online. It may help patients whose doctors recommend radiation by testing a modern way to plan and deliver treatment more precisely.
