Safety run in Incidence of severe toxicities (ST) during the 1st cycle of treatment

Overview

Brief Summary

Safety run in To confirm the safety of cobimetinib when combined with atezolizumab in pediatric STS patients (≥6 months to <12 years). Phase II part To assess the clinical activity of cobimetinib combined with atezolizumab in 4 independent and parallel cohorts (20 patients in each cohorts) based on histological types: Rhabdomyosarcoma (RMS), Malign Peripheral Nerve Sheath Tumors (MPNST), Complex genomics sarcomas: Single genomic sarcoma.
