Birmingham, AlabamaAges 1–30 - NCT04563507RecruitingPhase 2
Immunotherapy plus hormone therapy for metastatic ER-positive breast cancer
This Phase 2 study tests a combination of immune-based treatments along with hormone (endocrine) therapy to slow or shrink advanced, hormone-receptor positive, HER2-negative breast cancer. You may be a candidate if your cancer has progressed after standard hormone-blocking medicines and you can start treatment with CDK4/6 medicine plus an aromatase inhibitor.
New York, New YorkAges 18–90 - NCT04589624RecruitingPhase 1
MRI scan to monitor response in head and neck cancers
This Phase 1 study tests an investigational MRI scan (hpMRI) to help doctors see how thyroid cancer and other head-and-neck cancers respond to treatment like radiation or other medicines. If you’re eligible, the scan may help track treatment effects more closely, though it’s still being studied for this purpose.
Houston, TexasAges 18 years+ - NCT04603209Recruiting
Check-in registry for radiation during breast-conserving surgery
This registry study tracks people with early-stage, single-area breast cancer to understand outcomes when radiation is given during breast-conserving surgery. It may help doctors improve treatment planning for patients like you.
Santa Monica, CaliforniaAges 18 years+ - NCT04648462Recruiting
Proton therapy planning for certain brain tumors
This study builds and tests how proton therapy planning could better protect the brain compared with standard radiation (photon therapy) for adults with certain brain tumors. It may help reduce radiation to sensitive areas like the hippocampus, with the goal of better long-term brain function.
Maastricht, LimburgAges 18 years+ - NCT04668872Recruiting
Biopsy after liver radiation to see tumor cell changes
This trial gives radiation to liver tumors and then takes a small tissue sample (biopsy) to look for changes in the cancer cells after treatment. The goal is to learn what the radiation is doing inside the tumor, which may help improve future treatments.
New York, New YorkAges 18 years+ - NCT04671940Recruiting
Study tumor DNA changes during robot surgery after radiation
This study looks at how a cancer’s DNA changes over time in people who had head and neck cancer treated with radiation and then need robot-assisted surgery. It may help doctors understand why some cancers come back or persist and how to better plan treatment.
LondonAges 19 years+ - NCT04678401RecruitingPhase 1
Trial tests transplant using a half-matched donor for high-risk leukemia
This Phase 1 trial tests a special bone marrow transplant using a related “half-matched” donor (haploidentical), without a specific immune-suppressing medicine (“IS-free”). It’s for adults with certain high-risk AML or MDS to see if this approach can improve control of the disease while tracking safety.
Boston, MassachusettsAges 18–75 - NCT04683653RecruitingPhase 1/Phase 2
Pelvic radiation test for uterine or cervical cancer
This trial studies a specific radiation schedule aimed at the pelvis (lower belly area) for uterine or cervical cancer. It looks at whether this “hypofractionated” approach can control cancer while limiting side effects, especially in patients whose disease has not spread to distant organs.
Atlanta, GeorgiaAges 18 years+ - NCT04699773Recruiting
Laser treatment then focused radiation for new brain gliomas
This trial studies a two-step treatment for newly diagnosed high-grade glioma: first laser treatment (LITT) to target the tumor, followed by a shorter, more focused course of radiation. It may help shrink or control the tumor while limiting treatment time.
Baltimore, MarylandAges 18 years+ - NCT04700527RecruitingPhase 1/Phase 2
SCFA supplements during belly/pelvis radiation for cancer
