Maastricht, LimburgAges 18 years+ - NCT04947254RecruitingPhase 2
Add niraparib to hormone therapy after prostate radiation
This Phase 2 trial tests whether adding niraparib to standard hormone therapy (androgen ablation) after radiation works better for men with high-risk, localized or locally advanced prostate cancer. It may help control the cancer for longer, while also collecting extra tissue and blood to study why the treatment works or doesn’t.
Houston, TexasAges 18 years+ - NCT04947280RecruitingPhase 1/Phase 2
Radiation split into small doses for breast cancer bone spread
This trial studies a type of focused radiation given in smaller parts to treat bone metastases from breast cancer. It may help shrink tumors and improve control of pain or growth when standard treatments haven’t worked or surgery isn’t possible.
Shanghai, Shanghai MunicipalityAges Any age - NCT04968990RecruitingPhase 2
New Wilms tumor treated with proton beam abdominal radiation
This trial studies a specific type of radiation (proton beam) given to the abdomen after surgery and/or chemotherapy in children and young people with newly diagnosed Wilms tumor. The goal is to improve cancer control while carefully targeting radiation to the right stage of disease.
Memphis, TennesseeAges Any age - NCT04974671RecruitingPhase 2
SBRT radiation for limited cancer growth on immunotherapy
This trial tests whether targeted external-beam radiation (SBRT) can control a small number of progressing kidney cancer spots while you continue immune checkpoint inhibitor immunotherapy. It may help shrink or stop those specific “oligoprogressive” lesions and prolong benefit from your current immunotherapy.
New Haven, ConnecticutAges 18 years+ - NCT04977375RecruitingPhase 1/Phase 2
Anti–PD-1 treatment plus focused radiation for recurrent glioblastoma
This trial tests a cancer-immunotherapy medicine (an anti–PD-1 antibody, similar to pembrolizumab) combined with precisely targeted radiation to treat glioblastoma that has come back or progressed. It may help your immune system recognize and attack the tumor while the radiation targets the cancer.
Los Angeles, CaliforniaAges 18 years+ - NCT04985032Recruiting
Radiation after lumpectomy for selected breast tumors
This trial tests a shorter, focused type of radiation (APBI using SBRT) after lumpectomy for certain early breast cancers. It may help by targeting only the part of the breast where the tumor was, rather than treating the whole breast, while keeping safety and cancer control in mind.
Stuart, FloridaAges 50–100 - NCT04990921RecruitingPhase 2
Palliative radiation plus pembrolizumab for metastatic breast cancer
This trial studies whether adding a focused, comfort-focused form of radiation (SBRT) to pembrolizumab can help people with stage IV breast cancer that cannot be removed with surgery. You may be eligible if you can receive palliative SBRT and have measurable tumors, and if you meet prior-therapy and blood/health criteria.
Louisville, KentuckyAges 18 years+ - NCT05024097RecruitingPhase 2
New medicines with chemotherapy after short radiation for rectal cancer
This trial tests two new immune-related medicines (an anti–PD-1 drug and an adenosine blocker) added to standard chemotherapy after a short course of radiation for rectal cancer. It aims to improve cancer control while checking safety.
New York, New YorkAges 18–90 - NCT05032768Recruiting
Study links between skin bacteria and radiation skin reactions
This study looks at how changes in the skin’s normal bacteria (microbiome) relate to getting redness, irritation, or rash after breast radiation. It may help doctors predict who is more likely to have skin side effects after reconstruction and radiation.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT05039632RecruitingPhase 1/Phase 2
NBTXR3 plus radiation with anti-PD-1 for advanced lung or liver cancers
This study tests whether adding NBTXR3 (given into a tumor) and targeted radiation to anti–PD-1/PD-L1 immunotherapy can improve cancer control in advanced cancers that have spread to the lung and/or liver. Participants may be assigned to different radiation approaches to try to trigger tumor shrinkage in both treated and nearby or distant tumor areas.
Houston, TexasAges 18 years+ - NCT05047094Recruiting
DaRT radiation plus pembrolizumab for head and neck cancer
This trial tests whether a targeted internal radiation treatment (DaRT) combined with pembrolizumab (an immune therapy) can shrink recurrent or metastatic head and neck squamous cell cancer that cannot be fully removed with surgery. It may help by making cancer more visible to the immune system while delivering localized radiation to a tumor area.
JerusalemAges 18 years+ - NCT05059379RecruitingPhase 3
Different radiation fields after breast cancer surgery
This trial compares two ways of giving radiation to lymph node areas near the collarbone after surgery for invasive breast cancer. It aims to see which radiation approach works better and is safer for preventing cancer returning in these lymph nodes.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05068232RecruitingPhase 2
Durvalumab plus targeted radiation for metastatic small cell lung cancer
This Phase 2 study tests durvalumab (an immunotherapy) together with focused, ablative radiation to treat metastatic small cell lung cancer. It may help shrink tumors and improve outcomes, especially when at least one tumor can be safely targeted with this radiation plan.
Chicago, IllinoisAges 18 years+ - NCT05079763Recruiting
Hydrogel treatment to reduce skin damage after breast radiation
This trial tests a bacterial cellulose–based gel with a soothing ingredient (monolaurin) to help prevent or lessen painful skin reactions in the area receiving breast radiation. It focuses on people who have already finished surgery and chemotherapy and are about to start a planned radiation treatment schedule.
ManilaAges 18–80 - NCT05083754RecruitingPhase 1
New glioblastoma trial testing immune drug plus radiation
This Phase 1 study tests whether adding an immune therapy called retifanlimab to radiation (and a chemotherapy medicine called temozolomide, in some parts of the study) is safe and helpful for newly diagnosed glioblastoma patients after surgery with carmustine wafers. It aims to see how well this combination controls the cancer and what side effects are expected.
Baltimore, MarylandAges 18–100 - NCT05100095RecruitingPhase 2
Radiation schedule study for Merkel cell skin cancer
This Phase 2 trial tests a specific radiation timing/dose schedule for Merkel cell carcinoma (MCC), a rare and aggressive skin cancer. It may help by improving control of the cancer after surgery, especially in higher-risk cases (like lymph nodes).
Houston, TexasAges 18 years+ - NCT05124912Recruiting
Laser treatment for recurrent brain metastases after prior SRS
This study tests whether repeating treatment with a laser (along with a small biopsy) can control brain metastases that have come back after earlier radiation called SRS. It may help people whose cancer is stable enough for surgery and who have a specific, reachable brain spot to target.
Los Angeles, CaliforniaAges 18 years+ - NCT05189054Recruiting
Radiation retreatment for very central chest tumors
