Overview
Brief Summary
This is an open-label, single-arm, phase II, multicenter study designed to evaluated the efficacy and safety of atezolizumab in combination with bevacizumab in PD-L1-selected patients with Stage IIIB-IV Non-Squamous NSCLC harbored EGFR mutation after EGFR TKI therapy.

Eligibility Criteria
Inclusion Criteria
- •Life expectancy ≥ 10 months
- •Histologically or cytologically confirmed stage IIIB, IIIC, or IV non-squamous NSCLC. Patients with tumors of mixed histology are eligible if the major histological component appears to be non-squamous.
- •No prior treatment for Stage IIIB, IIIC, or IV non-squamous NSCLC, with the following exceptions:
- •Patients with a sensitizing mutation in the EGFR gene must have experienced disease progression or were intolerant to treatment with one or more EGFR TKIs. Patients who have progressed on or were intolerant to first-line osimertinib or other thirdgeneration EGFR TKIs are eligible.
- •Patients who have progressed on or were intolerant to first- or second-generation EGFR TKIs, and who have no evidence of the EGFR T790M mutation after TKI therapy are eligible.
- •Patients who have progressed on or were intolerant to first- or second-generation EGFR TKIs and who have evidence of the T790M mutation must have also progressed on or were intolerant to osimertinib to be eligible.
- •TKIs approved for treatment of NSCLC discontinued \>7 days prior to enrollment.
- •Measurable disease per RECIST v1.
- •PD-L1 expression of ≥1% as documented through central testing of a representative tumor tissue specimen either from previously obtained archival tumor tissue or tissue obtained from a biopsy at screening
- •ECOG Performance Status of 0-1
Exclusion Criteria
- •Symptomatic, untreated, or actively progressing central nervous system (CNS) metastases as determined by CT or MRI evaluation during screening and prior radiographic assessments
- •History of leptomeningeal disease
- •Prior chemotherapy or other systemic therapy for stage IIIB, IIIC, or IV disease
- •Active or history of autoimmune disease or immune deficiency
- •History of idiopathic pulmonary fibrosis, organizing pneumonia, drug-induced pneumonitis, or idiopathic pneumonitis, or evidence of active pneumonitis on screening chest computed tomography (CT) scan
- •Active tuberculosis
- •Significant cardiovascular disease within 3 months prior to initiation of study treatment, unstable arrhythmia, or unstable angina
- •History of malignancy other than NSCLC within 5 years prior to screening, with the exception of malignancies with a negligible risk of metastasis or death
- •Prior allogeneic stem cell or solid organ transplantation
- •Treatment with a live, attenuated vaccine within 4 weeks prior to initiation of study treatment, or anticipation of need for such a vaccine during atezolizumab treatment or within 5 months after the final dose of atezolizumab
