Brief Title  ICMJE Cobimetinib and Atezolizumab in Treating Participants With Advanced or Refractory Rare Tumors
Official Title  ICMJE A Phase II, Open-Label, Single-Arm, Multi-Cohort, Proof-of-Principle Study to Investigate the Efficacy of Cobimetinib and Atezolizumab in Advanced Rare Tumors
Brief Summary This phase II trial studies how well cobimetinib and atezolizumab work in treating participants with rare tumors that have spread to other places in the body (advanced) or that does not respond to treatment (refractory). Cobimetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cobimetinib and atezolizumab may work better in treating participants with advanced or refractory rare tumors.
Detailed Description

PRIMARY OBJECTIVE:

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.

SECONDARY OBJECTIVES:

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.

OUTLINE:

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.

Eligibility Criteria  ICMJE

Inclusion Criteria:

  • Patients must be informed of the investigational nature of this study and must be willing to give written informed consent in accordance with institutional and federal guidelines. Patients must be able to comply with the requirements and assessments of the study protocol
  • Must have histologically or cytologically documented rare tumor as defined per protocol that is metastatic or locally advanced and unresectable. Patients with locally advanced cutaneous squamous cell carcinoma that are technically resectable but in whom surgery is expected to lead to substantial function impairment or disfigurement are eligible
  • Must be refractory or intolerant to standard lines of therapy
  • Must have completed prior chemotherapy, immunotherapy, or radiation therapy at least 14 days prior to start of treatment and all toxicity must be resolved to Common Terminology Criteria for Adverse Events (CTCAE) v4.0 grade 1 (with the exception of CTCAE v4.0 grade 2 neuropathy) prior to start of treatment
  • Presence of radiographically evaluable disease
  • Eastern Cooperative Oncology Group (ECOG) performance status of =< 2
  • Tissue Parameters: a. Representative formalin-fixed paraffin-embedded (FFPE) tumor specimens in paraffin blocks (blocks are preferred) or at least 4 unstained slides, with an associated pathology report, for testing of tumor PD-L1 expression (tumor tissue from bone metastases is not evaluable for PD-L1 expression and is therefore not acceptable). b. Tumor tissue should be of good quality based on total and viable tumor content. Fine needle aspiration, brushing, cell pellet from pleural effusion, bone metastases, and lavage samples are not acceptable. For core-needle biopsy specimens, at least three cores should be submitted for evaluation. c. Patients who do not have tissue specimens meeting eligibility requirements must be willing to undergo a biopsy during the screening period
  • Absolute neutrophil count (ANC) >= 1,000/mcL (obtained within 14 days prior to enrollment)
  • Platelets >= 75,000/mcL (obtained within 14 days prior to enrollment)

  • Calculated creatinine clearance > 30 ml/min (obtained within 14 days prior to enrollment)
  • Aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) =< 3 x institutional upper limit of normal (IULN) without liver mets or =< 5 x IULN with liver metastases (obtained within 14 days prior to enrollment)
  • Bilirubin =< 1.5 mg/dL (obtained within 14 days prior to enrollment)
  • Able to swallow pills

At the discretion of the Investigator, acceptable methods of contraception may include total abstinence in cases where the lifestyle of the patient ensures compliance. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, post ovulation methods] and withdrawal are not acceptable methods of contraception)
