This study tests new blood tests and MRI scans to see how well your liver works during radiation therapy for liver cancer. It may help doctors better plan treatment and monitor your liver health.
The Bronx, New YorkAges 18 years+ - NCT05907681Recruiting
Study outcomes after precise targeted radiation for metastatic breast cancer
This study follows people with breast cancer that has spread to other parts of the body who receive a highly precise form of radiation (like IMRT, SBRT, or proton therapy). It aims to see how well this treatment strategy works and what outcomes patients experience.
SeoulAges 19–100 - NCT05933733Recruiting
Salvage treatment for breast cancer that returned locally
This trial looks at how well “salvage” treatments work for breast cancer that has come back only in the local area (like the chest wall or nearby lymph nodes), without spreading to distant organs. It also tracks side effects to better understand the risks and benefits for patients who need additional treatment.
SeoulAges 18–100 - NCT06885879Recruiting
Studying ctDNA changes after radiation for liver cancer
This trial studies how radiation therapy (SBRT) affects a DNA fragment in the blood called ctDNA in people with liver cancer. By tracking ctDNA changes, doctors hope to better understand how well the treatment is working and possibly predict outcomes earlier.
Hong KongAges 18 years+ - NCT06867484Recruiting
Breast re-irradiation after second lumpectomy
This trial tests whether giving a second round of radiation to the breast after a lumpectomy for a recurrence is safe and effective. It is for people with a specific type of breast cancer (ER+HER2-) who meet strict criteria regarding prior radiation and tumor characteristics.
Boca Raton, FloridaAges 40 years+ - NCT06864533Recruiting
Chemotherapy after surgery for aggressive prostate cancer
This trial tests whether adding chemotherapy after standard treatment helps people with a very aggressive type of prostate cancer (Gleason score 9-10). It is designed for those who have not had their cancer spread to distant parts of the body and are healthy enough to handle chemotherapy.
Beijing, Beijing MunicipalityAges 18–80 - NCT06828380RecruitingPhase 2
Immunotherapy with or without radiation for liver cancer
This trial tests whether using immunotherapy alone works as well as immunotherapy combined with radiation for liver cancer that has spread into major blood vessels. The goal is to find the best treatment option for people with this specific type of advanced liver cancer.
GoyangAges 19 years+ - NCT06835725RecruitingPhase 2
Comparing two prostate radiation schedules for intermediate risk
This trial compares giving radiation in 2 treatments versus 5 treatments for prostate cancer that hasn't spread. It's for men with low or intermediate risk prostate cancer who are healthy enough to undergo a short course of targeted radiation.
Surrey, British ColumbiaAges 18 years+ - NCT06831526RecruitingEarly Phase 1
Chemoradiation with or without azeliragon for new glioblastoma
This trial tests whether adding the study drug azeliragon to standard radiation and chemotherapy can help people with newly diagnosed glioblastoma. The study will also look at how the tumor responds to the added drug.
St Louis, MissouriAges 18 years+ - NCT06816927RecruitingPhase 2
Immunotherapy trial for glioblastoma with nivolumab and relatlimab
This trial tests whether two immunotherapy drugs, nivolumab and relatlimab, can help treat glioblastoma (GBM), a type of brain tumor. It is for people newly diagnosed or who haven't had radiation or chemotherapy yet and are scheduled for surgery.
New York, New YorkAges 18 years+ - NCT06820385Recruiting
Wearable AI device for daily radiation therapy guidance
This trial tests a wearable device that uses artificial intelligence to help guide radiation therapy for pelvic cancers. The device may help make daily treatments more accurate, which could improve outcomes and reduce side effects.
