This is a multinational, double-blind, randomized, parallel-group Phase 3 clinical trial evaluating the efficacy and safety of bevacizumab-Pfizer plus paclitaxel and carboplatin versus bevacizumab-EU plus paclitaxel and carboplatin in first-line treatment for patients with advanced (unresectable, locally advanced, recurrent or metastatic) non-squamous NSCLC.

Bevacizumab-Pfizer: 15 mg/kg IV on Day 1 of a 21-day cycle for each of at least 4 and no more than six (6) 21-day cycles, followed by the assigned blinded bevacizumab monotherapy.
bevacizumab-EU: 15 mg/kg IV on Day 1 of a 21-day cycle for each of at least 4 and no more than six (6) 21-day cycles followed by the assigned blinded bevacizumab monotherapy.
Paclitaxel 200 mg/m2 via IV infusions on Day 1 of a 21-day cycle for each of at least 4 and no more than six (6) 21-day cycles.
Objective Response Rate (ORR) by Week 19
ORR refers to percentage of participants who achieved complete response (CR) or partial response (PR) by Week 19 of the study in accordance with Response Evaluation Criteria in Solid Tumors (RECIST) v 1.1 which was subsequently confirmed by Week 25. A participant achieved CR if both target and non-target lesions achieved CR, no new lesions; achieved PR if target lesions achieved CR or PR, non-target lesions were assessed as non-CR/non-PD (progressive disease), indeterminate or missing, and no new lesions. For target lesions, CR: complete disappearance of all target lesions except nodal disease (target nodes must decrease to normal size); PR: \>= 30% decrease under baseline of the sum of diameters of all target measurable lesions. For non-target lesions, CR: disappearance of all non-target lesions and normalization of tumor marker levels and all lymph nodes must be normal in size; non-CR/non-PD: persistence of any non-target lesions and/or tumor marker level above the normal limits.
Time frame: 25 weeks
Number of Participants With Treatment-Emergent Adverse Events
AE was defined as any untoward medical occurrence in a clinical investigation participant administered a product or medical device, regardless of the causal relationship to study treatment. Treatment-emergent AEs (TEAEs) were defined as AEs which occurred for the first time during the effective duration of treatment or AEs that increased in severity during treatment. Serious AEs (SAEs) were defined as any untoward medical occurrence at any dose that resulted in death; was life-threatening (immediate risk of death); required inpatient hospitalization or caused prolongation of existing hospitalization; resulted in persistent or significant disability/incapacity (substantial disruption of the ability to conduction normal life functions). AEs included SAEs and non-serious AEs. Causality to study treatment was determined by the investigator. Severity was graded according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.03.

Laboratory evaluation included hematology (hemoglobin, white blood cells, platelets and absolute neutrophil count), blood chemistry (alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, total bilirubin, serum or plasma creatinine, sodium, potassium, total calcium, magnesium, blood urea nitrogen or urea, and albumin ), coagulation (international normalized ratio for prothrombin time and activated partial thromboplastin time) and urinalysis (dipstick followed by a quantitative urine protein analysis for results of 2+ or greater).
Time frame: 55 weeks
Duration of Response (DOR)
DOR was defined as the time from date of the first documentation of objective tumor response (CR or PR) to the first documentation of PD or to death due to any cause in the absence of documented PD. DOR was based on the Brookmeyer and Crowley method.
Time frame: 55 weeks
Progression Free Survival Rate at 55 Weeks
This outcome measure refers to the possibility of being progression free at 55 weeks since start of study treatment, estimated from the Kaplan-Meier curve using the product-limit method.
Time frame: 55 weeks
Survival Rate at 55 Weeks
This outcome measure refers to the possibility of being alive at 55 weeks since start of study treatment, estimated from the Kaplan-Meier curve using the product-limit method.
Time frame: 55 weeks
Serum Concentration of Bevacizumab up to 1 Year
Time frame: Pre-dose from Cycle 1 to Cycle 17, 2.5 hours post-dose in Cycle 1, and 1.5 hours post-dose in Cycle 5
Number of Participants With Anti-Drug Antibody (ADA)
ADA assay was performed using a sensitive, specific, and semi-quantitative electrochemiluminescent (ECL) method, which used biotinylated- and ruthenium-labeled PF-06439535 as reagents. Samples with ADA titer greater than or equal to (\>=) 2.29 were considered positive.
Time frame: 55 weeks
Number of Participants With Neutralizing Antibody (NAb)
Only samples that were confirmed positive for ADA were further tested for NAb. The NAb analysis was conducted using a single validated quasi-quantitative enzyme-linked immunosorbent assay (ELISA) that utilized PF-06439535 as a reagent. Samples with NAb titer \>=1.70 were considered positive.
