I. To evaluate the efficacy of cobimetinib plus atezolizumab (COTEZO) in cohorts of advanced rare tumors using objective response rate (ORR) per Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1.
I. To determine progression-free survival (PFS) on COTEZO in cohorts of advanced rare tumors per RECIST v1.1 and immune-related (ir)RECIST.
II. To determine overall survival (OS) on COTEZO in cohorts of advanced rare tumors.
III. To determine disease control rate (DCR) and duration of response (DOR) on COTEZO in cohorts of advanced rare tumors per RECIST v1.1 and irRECIST.
IV. To determine objective response rate (ORR) per immune-related RECIST criteria.
V. To determine safety profile and adverse events encountered by patients with advanced rare tumors treated with COTEZO.
VI. To collect and bank tumor tissue and peripheral blood for future correlative analyses from patients with advanced rare tumors treated with COTEZO.
Participants receive cobimetinib orally (PO) once daily (QD) on days 1-21 and atezolizumab intravenously (IV) over 60 minutes on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, participants followed up every 3 months thereafter.

Experimental: Treatment (cobimetinib, atezolizumab)
Participants receive cobimetinib PO QD on days 1-21 and atezolizumab IV over 60 minutes on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
- Overall Response Rate (ORR) [ Time Frame: 8 weeks ]ORR (partial response (PR) or complete response (CR) measured as per RECIST 1.1.
- Progression-Free Survival (PFS) [ Time Frame: 2 weeks after last dose of study drugs ]PFS assessed per RECIST v1.1.
- Progression-Free Survival (PFS) [ Time Frame: 2 weeks after last dose of study drugs ]PFS assessed per irRECIST.
