A Study of Bevacizumab, Carboplatin, and Paclitaxel or Pemetrexed With or Without Atezolizumab in Chemotherapy-Naïve Patients With Stage IV Non-Squamous Non-Small Cell Lung Cancer (IMpower151)

Histologically or cytologically confirmed Stage IV non-squamous NSCLCNo prior treatment for Stage IV non-squamous NSCLC, with the following exceptions: (1) Patients with a sensitizing mutation in the EGFR gene must have experienced disease progression (during or after treatment) or were intolerant to treatment with one or more EGFR TKIs, such as erlotinib, gefitinib, afatinib, dacomitinib, and osimertinib, or another EGFR TKI appropriate for the treatment of EGFR-mutant NSCLC. Patients who have progressed on or were intolerant to first-line osimertinib or other third-generation EGFR TKIs are eligible. Patients who have progressed on or were intolerant to first- or second-generation EGFR TKIs, such as erlotinib, gefitinib, afatinib, dacomitinib, and who have no evidence of the EGFR T790M mutation in the tumor tissue 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 in their tumor tissue must have also progressed on or were intolerant to osimertinib to be eligible. (2) Patients with an ALK gene rearrangement must have experienced disease progression or were intolerant to treatment with one or more ALK inhibitors, such as crizotinib, alectinib, ceritinib, brigatinib, ensartinib and lorlatinib that are appropriate for the treatment of NSCLC that has an ALK gene rearrangement. Availability of a representative tumor specimen that is suitable for the determination of PD-L1 status, as well as the presence of EGFR mutations and ALK gene rearrangements, via central testing. Treatment-free interval of at least 6 months from randomization since the last chemotherapy, radiotherapy, or chemoradiotherapy treatment for patients who have received prior neoadjuvant and/or adjuvant chemotherapy, radiotherapy, or chemoradiotherapy with curative intent for non-metastatic disease Measurable disease, as defined by RECIST v1.1 Eastern Cooperative Oncology Group Performance Status of 0 or 1 Life expectancy >=3 months Adequate hematologic and end-organ function Negative HIV test at screening Negative hepatitis B surface antigen (HBsAg) test at screening Negative total hepatitis B core antibody (HBcAb) test at screening, or positive total HBcAb test followed by a negative hepatitis B virus (HBV) DNA test at screening Negative hepatitis C virus (HCV) antibody test at screening, or positive HCV antibody test followed by a negative HCV RNA test at screening For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods, and agreement to refrain from donating eggs For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use a condom, and agreement to refrain from donating sperm
