To determine the objective intracranial response rate of the combination of bevacizumab and atezolizumab in patients with active melanoma brain metastases (MBM) as measured by a modified immunotherapy Response Assessment in Neuro-oncology (iRANO) criteria measured by magnetic resonance imaging (MRI) of the brain. II. To assess the safety, tolerability, and preliminary efficacy of the triplet combination of atezolizumab (Tencentriq), bevacizumab (Avastin), and cobimetinib (Cotellic). (TACo) SECONDARY OBJECTIVES: I. Safety and tolerability of bevacizumab + atezolizumab. II. Safety and tolerability of the combination of atezolizumab + bevacizumab + cobimetinib in patients with BRAFV600 wild-type metastatic melanoma to the brain who've experienced prior progression on anti-PD1. III. Overall response rates (intracranial + extracranial) using a modified version of iRANO and compared to modified Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 and Response Assessment in Neuro-oncology - Brain Metastases (RANO-BM). IV. Duration of response intracranially and extracranially. V. Progression-free survival. VI. Overall survival. VII. Immune modulation. VIII. Changes in circulating cell free deoxyribonucleic acid (cfDNA) as determinants of response and markers of early progression. IX. Changes in relative apparent diffusion coefficient as measured by MRI as early predictor of response. X. Changes in neurocognitive function and health-related quality of life. XI. Molecular and immunological changes demonstrated in extracranial lesions. OUTLINE: Patients are assigned to 1 of 2 arms. ARM I: Patients receive atezolizumab intravenously (IV) over 30-60 minutes and bevacizumab IV over 30-90 minutes on day 1.
