This trial studies whether adding propranolol (a common blood-pressure/heart medication) to standard chemotherapy and radiation can improve outcomes for people with esophageal adenocarcinoma. You would start propranolol around the time of treatment, with careful heart monitoring and study follow-up.
Buffalo, New YorkAges 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+ - 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+ - NCT04992650Enrolling by invitation
Ultrasound imaging during breast reconstruction after mastectomy and radiation
This study uses ultrasound pictures to better understand blood flow in breast reconstruction sites after a mastectomy, when you also need radiation therapy. It may help improve how clinicians monitor and manage healing and treatment effects in this situation.
Rochester, MinnesotaAges 18 years+ - 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 - NCT04861194Recruiting
Test treatment plans to preserve erections during prostate radiation
This trial studies ways to help preserve erectile function while you receive radiation treatment for prostate cancer. It may help by aiming to protect erections, especially for people at low to intermediate risk.
Utrecht, UtrechtAges 18 years+ - NCT04927897Recruiting
Testing where to aim extra rectal radiation before surgery
This trial tests the best place to target an “extra boost” of radiation inside the rectum for certain rectal cancer patients. It may help guide more precise treatment planning before they have total mesorectal excision (TME) surgery.
Maastricht, LimburgAges 18 years+ - NCT04881487Recruiting
Radiation treatment for local pancreatic cancer recurrence
This trial looks at additional treatment using a special type of focused radiation (stereotactic body radiation therapy) for pancreatic cancer that has come back only in the same area after surgery. It may help by controlling the local recurrence and possibly improving outcomes for people whose cancer has not spread elsewhere.
Amsterdam, North HollandAges 18 years+ - NCT04787744RecruitingPhase 2/Phase 3
Test standard prostate cancer treatment with or without targeted spot radiation
This study tests whether adding targeted local treatment (like radiation to a few spots seen on scans) improves outcomes for some people with limited (oligometastatic) prostate cancer. It compares standard systemic therapy alone versus standard therapy plus PET-scan–guided spot treatment.
Long Beach, CaliforniaAges 18 years+ - NCT04852887RecruitingPhase 3
Testing shorter breast radiation after low-risk hormone breast cancer
This Phase 3 trial studies whether “less intense” radiation can work as well as standard radiation for certain early-stage hormone receptor–positive, HER2-negative breast cancers that have a low Oncotype DX score. It may help reduce treatment burden while keeping cancer control strong.
Birmingham, AlabamaAges 50–70 - NCT04774419RecruitingPhase 2
Radiation plus dostarlimab for post-surgery endometrial cancer
This Phase 2 study tests whether adding dostarlimab (an immunotherapy medicine) to radiation after surgery can lower cancer returning and improve outcomes. It’s for people with certain endometrial cancers found to have specific genetic/molecular changes and who have stage III/IVA disease after surgery.
Basking Ridge, New JerseyAges 18 years+ - NCT04846309RecruitingPhase 1
MRI scan to personalize radiation for esophageal cancer
This Phase 1 study uses specialized imaging (including MRI) to better “see” low-oxygen areas in esophageal cancer and help guide individualized radiation treatment. It aims to improve how radiation is planned and delivered while checking safety.
Salt Lake City, UtahAges 18 years+ - NCT04782752Recruiting
Radiation before lung transplant to help stop lung cancer spread
This study tests a focused, low-dose type of radiation given before a lung transplant. The goal is to help your immune system recognize and attack cancer cells (called “radiovaccination”) and improve outcomes for people who cannot get curative treatment with surgery or SBRT alone.
Toronto, OntarioAges 18 years+ - NCT04725903Recruiting
Proton beam radiation for high-risk prostate cancer
This trial tests proton radiation therapy for people with high-risk prostate cancer. It may help by delivering radiation in a more targeted way, with the goal of controlling the cancer while reducing exposure to nearby healthy tissue.
Atlanta, GeorgiaAges 18 years+ - NCT04703101RecruitingPhase 1
Short radiation plus chemo for stage II–III rectal cancer
This trial tests a short course of radiation therapy combined with chemotherapy for people with stage II or III rectal cancer. It’s designed to see whether this approach is safe and effective before or around cancer surgery.
Los Angeles, CaliforniaAges 18 years+ - NCT04701749Recruiting
Stopping blood thinners with a left-atrial device in bleeding risk
This trial studies whether it’s safe to temporarily stop blood-thinning medicine in people with long-term atrial fibrillation who have bleeding from a radiation-damaged bladder. It uses a procedure with a device placed in the left atrium to help lower stroke risk while reducing bleeding risk.
Clermont-FerrandAges 18 years+ - NCT04693377Recruiting
Freezing tumor treatment plus targeted radiation for painful bone spread
This study tests whether combining a “freezing” procedure (cryoablation) with focused external radiation (SBRT) can reduce pain from bone metastases. It’s for people with certain cancers that have spread to bone and are having significant pain in a specific bone spot.
Houston, TexasAges 18 years+ - NCT04754321RecruitingPhase 1
Test immunotherapy with salvage surgery and IORT for head and neck cancer
This Phase 1 trial tests a new plan that combines immunotherapy with surgery, plus a targeted radiation treatment called IORT. It is for people whose head and neck squamous cell cancer has come back or never fully went away and can be operated on. The goal is to shrink or control the cancer and see how safe the approach is.
Columbus, OhioAges 18 years+ - NCT04683679RecruitingPhase 2
Radiation plus pembrolizumab and olaparib for certain breast cancers
This study tests whether adding the drugs pembrolizumab and olaparib (or similar “radiosensitizers”) to radiation can improve outcomes for women with advanced breast cancer that is triple-negative or ER-positive/Her2-negative. It’s designed for cancers that have spread or come back and where radiation is being considered to control disease.
Basking Ridge, New JerseyAges 18 years+ - NCT04615013RecruitingPhase 1
NBTXR3 with chemoradiation for esophageal cancer treatment
This early-phase study tests adding NBTXR3 (a special treatment given into the tumor) to standard chemotherapy and radiation for esophageal cancer. The goal is to see if it can improve cancer control and to learn about safety and dosing.
