Inclusion criteria

* The participant has Stage IV NSCLC. * Part A: NSCLC Stage IV (any type) * Part B: NSCLC Stage IV (squamous and nonsquamous) * Part C: NSCLC Stage IV in Japanese participants (squamous and nonsquamous) * The participant must have progressed after 1 platinum-based chemotherapy regimen for Stage IV NSCLC. Prior therapy with VEGF/VEGFR targeting agents is permitted. Prior neoadjuvant/adjuvant therapy is permitted. Prior treatment with EGFR-TKI and ALK inhibitors is mandatory in participants with NSCLC whose tumor has EGFR-activating mutations or ALK translocations, respectively. * Measurable disease at the time of study entry as defined by Response Evaluation Criteria In Solid Tumors Version 1.1 (RECIST 1.1). * The participant has evaluable tumor tissue available for biomarker analyses. * The participant has adequate organ function. * Eastern Cooperative Oncology Group performance status (ECOG PS) score of 0-1.

Exclusion criteria

* The participant is currently enrolled in a clinical trial involving an investigational product or non-approved use of a drug or device. * Prior treatment with an anti-PD-1, anti-PD-L1, anti-PD-L2 monoclonal antibody. * Have a serious concomitant systemic disorder or significant cardiac disease. * The participant has undergone major surgery or received anti-cancer monoclonal antibody therapy in the 30-days prior to study enrollment. * The participant has undergone chest irradiation within 2 weeks prior to receiving study treatment. * The participant has brain metastases that are symptomatic. * The participant has a history of arterial thromboembolism event (ATE) or venous thromboembolism event (VTE) within 3 months prior to study enrollment.

Number of Participants With Dose Limiting Toxicities (DLTs) in Part A and Part CBaseline through Cycle 1 (21 day cycles)A dose limiting toxicity (DLT) was defined as an adverse event (AE) during the first 21 days that was possibly related to the study drug and fulfilled any of the following criteria using the National Cancer Institute's (NCI) Common Terminology Criteria for Adverse Events (CTCAE), Version 4.0: Grade 3 or 4 nonhematologic toxicity, Grade 4 nausea, vomiting, or diarrhea that persists more than 3 days despite maximal supportive intervention, Grade 3 thrombocytopenia with bleeding requiring transfusion, Grade 4 thrombocytopenia with or without bleeding, Grade 4 neutropenia that persists more than 5 days, Grade 3 or 4 neutropenia with fever, Grade ≥3 skin toxicity despite best supportive care with some exceptions, if a total at least 75% of the planned dose for both agents cannot be administered in the first cycle due to toxicity, prolonged delay (\>2 weeks) in initiating cycle 2 due to treatment-related toxicity and Grade 5 toxicity.
Percentage of Participants Who Achieve Best Overall Tumor Response of Complete Response (CR) or Partial Response (PR) (Objective Response Rates [ORR]) in Part A and Part BBaseline to Measured Progressive Disease or Start of New Anti-Cancer Therapy (Up To 16 Months)ORR was the percentage of participants achieving a best overall response (BOR) of complete response (CR) or partial response (PR) as per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. CR defined as the disappearance of all target and non-target lesions and no appearance of new lesions. PR defined as at least a 30% decrease in the sum of the longest diameters (LD) of target lesions (taking as reference the baseline sum LD), no progression of non-target lesions, and no appearance of new lesions. Progressive disease (PD) is defined as at least a 20% increase in the sum of the diameters of target lesions, with reference being the smallest sum on study and an absolute increase of at least 5 mm, or unequivocal progression of non-target lesions, or 1 or more new lesions.

Secondary

Progression Free Survival (PFS) in Part A Cohort 2 and Part B

PFS was defined as the time from the date of first dose of study drug until first observation of objective (radiographically documented) PD as defined by RECIST v1.1 or death from any cause, whichever comes first. PD is defined as at least a 20% increase in the sum of the diameters of target lesions, with reference being the smallest sum on study and an absolute increase of at least 5 mm, or unequivocal progression of non-target lesions, or 1 or more new lesions.

Time frame: Baseline to Measured Progressive Disease or Death Due to Any Cause (Up To 16 Months)

Population: All participants who received at least one dose of study drug and who had evaluable data in Part A Cohort 2 and Part B. 21 participants were censored. Per protocol, participants in Part A cohort 2 who received the recommended necitumumab dose for Part B were also analyzed together with Part B.
