Abstract
TPS9600 Background: Nivolumab combined with ipilimumab is active in melanoma brain metastases, with intracranial response rates > 55% and durable survival in treatment naïve patients (pts) (Long GV et al Lancet Onc 2018; Tawbi H et al NEJM 2018). We seek to determine if the addition of stereotactic radiotherapy (SRS) results in improved intracranial outcomes. Methods: This is a multisite, open-label, phase 2 trial in systemic treatment-naïve pts with melanoma brain metastases. Pts must have ≥1 asymptomatic brain metastases that are ≥5mm and ≤40mm as per modified RECIST 1.1, on gadolinium-enhanced MRI, and no history of previous treatment with SRS. Eligible pts are randomly assigned to eithe..
