Key Inclusion Criteria: * Histologically confirmed, locally advanced (unresectable) or metastatic nonsquamous NSCLC * Documented absence of tumor activating EGFR mutation, ALK gene and ROS1 rearrangements, and alterations in any actionable driver oncogenes for which there are locally approved targeted first-line therapies * PD-L1 IHC testing documenting TPS \< 49% * No prior systemic treatment for advanced/metastatic NSCLC. * Measurable disease by RECIST 1.1 * ECOG performance status score of 0 or 1 * Life expectancy ≥ 3 months * Adequate liver, kidney, thyroid and bone marrow function Key Exclusion Criteria: * Have known active central nervous system metastases and/or carcinomatous meningitis. Patients with treated brain metastases may participate, provided they are radiologically stable * Active known or suspected autoimmune disease * Has any condition requiring systemic treatment with corticosteroids, prednisone equivalents, or other immunosuppressive medications within 14 days prior to first dose of study drug * Interstitial lung disease that is symptomatic * Known human immunodeficiency virus (HIV) positive with CD4+ T-cell (CD4+) count \< 350 cells/μL, or an HIV viral load greater than 400 copies/mL, or a history of an acquired immunodeficiency syndrome-defining opportunistic infection within the past 12 months, or not on established antiretroviral therapy (ART) for at least 4 weeks prior to initiation of study drug dosing. (HIV positive subjects who do not meet these exclusion criteria are eligible) * Positive test for hepatitis C RNA (a patient who is hepatitis C virus \[HCV\] antibody positive but HCV RNA negative due to documented, curative prior antiviral treatment or natural resolution is eligible) * Positive test for hepatitis B surface antigen or hepatitis B core antibody (hBcAb) (a patient whose hBsAg is negative and hBcAb is positive may be enrolled if a hepatitis B virus (HBV) DNA test is negative and the subject is retested for HbsAg and HBV DNA every 2 months) * History or evidence of any clinically unstable/uncontrolled disorder, condition, or disease (including, but not limited to, cardiopulmonary, renal, metabolic, hematologic, or psychiatric) other than NSCLC, that, in the opinion of the Investigator, would pose a risk to patient safety or interfere with study evaluations, procedures, or completion Other protocol defined inclusion/exclusion criteria apply.
