      Trial Summary

      This study will evaluate the preliminary efficacy, safety, and pharmacokinetics of cobimetinib and atezolizumab in participants with advanced BRAF V600-wild type (WT), metastatic, or unresectable locally advanced melanoma who have progressed on prior anti-PD-1 therapy. In addition, this study will evaluate the efficacy, safety, and pharmacokinetics of atezolizumab monotherapy in participants with BRAFV600-WT metastatic or unresectable locally advanced melanoma, who have not been previously treated.

      • Histologically confirmed Stage IV (metastatic) or unresectable Stage IIIc BRAF V600 WT (locally advanced) melanoma
      • Documentation of BRAF V600 mutation-negative status in melanoma tumor tissue (archival [< 5 years old] or newly obtained) through use of a clinical mutation test approved by the local health authority
      • Measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1
      • Disease progression on or after treatment with a programmed death (PD)-1 inhibitor either as monotherapy or in combination with other agent(s)

      Additional Disease-Specific Inclusion Criteria in Cohort B (Biopsy Cohort):

      • Progressed on or after anti-PD-1 therapy within 12 weeks before study start
      • Received a minimum of two cycles of anti-PD-1 therapy
      • Meet the following criteria for resistance to an anti-PD-1 agent: primary resistance defined as disease progression, according to RECIST v1.1, as best response; secondary resistance defined as disease progression after initial confirmed response according to RECIST v1.1
      • Consent to undergo tumor biopsies of accessible lesions, before and during treatment and at radiographic progression, for biomarker analyses.
      • Have at least two accessible lesions that are amenable to excisional or core-needle (minimum three cores and minimum diameter 18 gauge; however, 16 gauge is desirable) biopsy without unacceptable risk of a major procedural complication. Exceptions may be made if patient has only one lesion that allows multiple biopsies.

      Disease-Specific Inclusion Criteria: Cohort C:

      • Histologically confirmed Stage IV (metastatic) or unresectable Stage IIIc BRAFV600-WT (locally advanced) melanoma
      • Naive to prior systemic anti-cancer therapy for melanoma
      • Documentation of BRAFV600 mutation-negative status in melanoma tumor tissue (archival [< 5 years old] or newly obtained) through use of a clinical mutation test approved by the local health authority
      • A representative, formalin-fixed, paraffin-embedded (FFPE) tumor specimen in a paraffin block (preferred) or 20 slides containing unstained, freshly cut, serial sections must be submitted along with an associated pathology report prior to study entry.
      • Measurable disease according to RECIST v1.1.

      General Inclusion Criteria:

      • Ability to comply with the study protocol, in the investigator's judgment
      • Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1
      • Available and adequate baseline tumor tissue sample
      • Life expectancy ≥ 18 weeks
      • Adequate hematologic and end-organ function, defined by laboratory test results, obtained within 14 days before initiation of study treatment
      • For women of childbearing potential: abstinent or use an effective form of contraceptive method for at least 3 months for cobimetinib and at least 5 months for atezolizumab. Women must refrain from donating eggs during this same period.
      • For men: abstinent or use contraceptive measures and agreement to refrain from donating sperm for at least 3 months after cobimetinib and atezolizumab
      Exclusion Criteria
      • Prior treatment with a mitogen activated-protein kinase (MAPK) inhibitor
