EXCLAIM: Exploring Combined Local and Systemic Approaches In Brain Metastasis: a Multi-cohort Randomized Phase II Study Evaluating Initial Response to Systemic Therapy and Subsequent Integration of Stereotactic Radiosurgery in Patients With Low-risk Brain Metastases and Central Nervous System-active

To learn if consolidative stereotactic radiosurgery (cSRS) can help to control central nervous system (CNS) disease in patients who have brain metastases and have a partial response or stable brain metastases after systemic therapy. To learn if using SRS to treat all brain metastases that do not respond to systemic therapy versus treating only metastases that are getting worse can help to control CNS disease in patients whose disease gets worse after systemic therapy.
