Houston, TexasAges 18 years+ - NCT05116475RecruitingPhase 3
New prostate cancer trial adding darolutamide to standard treatment
This Phase 3 trial tests whether adding darolutamide to standard hormone therapy and radiation works better than standard treatment alone for newly diagnosed prostate cancer that has spread to pelvic lymph nodes. If you qualify, you may receive darolutamide or a placebo alongside long-term hormone therapy and radiation.
Chambray-lès-ToursAges 18–120 - NCT07070076Recruiting
Y-90 therapy vs chemo infusion for liver cancer
This study compares two liver-directed treatments—radioactive Yttrium-90 beads (SIRT) and a type of chemo infusion directly into the liver (HAIC)—for people whose liver cancer is advanced enough to need treatment but might still be removable with surgery. The goal is to see which approach can shrink the tumor best before surgery.
Guangzhou, GuangdongAges 18–75 - NCT01255748Recruiting
Registry study tracking outcomes after radiation treatment
This registry study collects information from people who are planning to receive radiation therapy. The goal is to better understand treatment outcomes and help improve radiation care over time.
Scottsdale, ArizonaAges Any age - 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+ - NCT01492972RecruitingPhase 3
Lighter radiation, with or without hormone suppression
This Phase 3 trial tests whether giving a smaller amount of radiation (“hypo-fractionated” means fewer, larger sessions) can work as well as standard approaches for intermediate-risk prostate cancer. It also compares adding hormone therapy (“androgen suppression”) to radiation versus using radiation alone.
Scottsdale, ArizonaAges 18 years+ - NCT07074470Recruiting
New drug combo for relapsed brain lymphoma
This trial tests a new combination of drugs (teniposide, a PD-1 checkpoint inhibitor, and selinexor) for people with relapsed or refractory primary central nervous system lymphoma. It aims to see if this three-drug approach can shrink tumors or slow the disease when previous treatments haven't worked.
Suzhou, JiangsuAges 18–75 - NCT03546829RecruitingPhase 1
Testing targeted radiation plus short anti-microbial treatment
This early safety study tests a combination of focused radiation and a targeted anti-microbial (antibiotic/antifungal/antiviral/anti-parasite) plan for certain lung cancer that is starting to progress in a few spots. It aims to see whether this approach is safe and helps control the small areas of progressing cancer after prior treatment.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06889649RecruitingPhase 2
SBRT plus immunotherapy and targeted therapy for kidney cancer
This trial tests a combination of targeted therapy (axitinib) and immunotherapy (toripalimab) alongside stereotactic body radiation therapy (SBRT) for kidney cancer that has come back or spread. It may be an option if you have a limited number of metastatic tumors that can be treated with radiation.
Beijing, Beijing MunicipalityAges 18–80 - 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+ - NCT06729814Recruiting
Repeated Breast Radiation Side Effects Study
This study asks whether having radiation therapy again to the same breast or chest (15 sessions over 3 weeks) causes more skin redness, peeling, or pain. The goal is to learn more about side effects so doctors can better prepare and support patients who need a second course of breast radiation.
Toronto, OntarioAges 18 years+ - NCT06826885Recruiting
Comparing two types of radiation for breast cancer
This trial is testing how well two different radiation techniques, IMPT and IMRT, work for treating breast cancer. It aims to see which one is safer and more effective, so you might benefit from a potentially better treatment approach.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06954831RecruitingPhase 2
