EFS: time from randomization till recurrence of high-grade disease, progression of disease, persistence of carcinoma in situ (CIS), death due to any cause, whichever occurred first. Recurrence of high-grade disease: re-appearance of high-grade disease after randomization/study intervention initiation, re-appearance of high-grade disease after complete response (CR) for CIS participants or re-appearance of high-grade disease before CR for CIS participants and concurrent papillary disease at baseline. Progression of disease defined as any of following: Lamina propria invasion, muscle invasive disease, lymph node positive disease, metastatic disease, high-grade stage of bladder cancer (non-invasive papillary carcinoma \[Ta\] or invasion into the lamina propria without invasion into the muscularis propria \[T1\]) in participants with CIS only at baseline before achieving CR. Persistence of CIS: persistent CIS after induction, re-induction. EFS estimated using Kaplan-Meier analysis.

This study included Asian participants with advanced solid tumors (Phase 1b) and global participants with first line (1L) and second line (2L) non-small cell lung cancer (NSCLC) (Phase 2). For the Phase 1b, any of the following AEs occurring during the DLT observation period (the first cycle of treatment) which were attributable to the investigational product were classified as DLTs: Grade 5 AE not clearly due to the underlying disease or extraneous causes; Hematologic toxicity; Non-Hematologic Toxicity; Delay of ≥ 3 weeks in receiving the next scheduled administration due to persisting treatment-related toxicities.

This study included Asian participants with advanced solid tumors (Phase 1b) and global participants with 1L and 2L NSCLC (Phase 2). AUCτ is area under the plasma concentration-time profile from time zero to the next dose (at steady state, starting at Week 12). (τ = X days, where X = 28 days for Q4W regimen and 42 days for Q6W regimen)

This study included Asian participants with advanced solid tumors (Phase 1b) and global participants with 1L and 2L NSCLC (Phase 2). Steady state Ctrough is pre-dose concentration following multiple dosing at steady state (Week 12)

DLT was defined as any of the following drug-related adverse events (AEs) occurring during the first cycle (21 days for IV dosing, 28 days for SC dosing) in Part 1: Grade 5 AE; Grade 4 neutropenia lasting \>5 days from initiation of granulocyte colony stimulating factor; Grade 4 thrombocytopenia with bleeding; Platelet transfusion requirement or a platelet count \<10,000/uL; Grade 4 non-hematologic AE; Grade 3 AE lasting \>7 days despite optimal supportive care; Grade 3 central nervous system AE regardless of duration; met criteria for drug induced liver injury. Severity of AEs were graded according to Common Terminology Criteria for Adverse Events (CTCAE) v4.03. Grade 3 = severe AE. Grade 4 = life-threatening consequences; urgent intervention indicated. Grade 5 = death related to AE.

AE = any untoward medical occurrence in participant who received study treatment without regard to possibility of causal relationship. Treatment-emergent events = between first dose of study treatment and up to 28 days after last dose that were absent before treatment or that worsened relative to pretreatment state. A serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Grades of severity were defined by CTCAE v4.03. Grades of severity were defined by CTCAE v4.03. Grade 3 = severe AE. Grade 4 = life-threatening consequences; urgent intervention indicated. Grade 5 = death related to AE.

Treatment-related AE was any untoward medical occurrence attributed to study treatment in a participant who received study treatment. Treatment-emergent events = between first dose of study treatment and up to 28 days after last dose that were absent before treatment or that worsened relative to pretreatment state. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-related AEs and SAEs were determined by the investigator. Grades of severity were defined by CTCAE v4.03. Grades of severity were defined by CTCAE v4.03. Grade 3 = severe AE. Grade 4 = life-threatening consequences; urgent intervention indicated. Grade 5 = death related to AE.

Following parameters were analyzed for laboratory examination: hematology (anemia, hemoglobin increased, lymphocyte count decreased, lymphocyte count increased, neutrophil count decreased, platelet count decreased, white blood cell decreased); chemistries (increase of alanine aminotransferase, alkaline phosphatase, aspartate aminotransferase, blood bilirubin, CPK, creatinine, gamma-glutamyl transferase \[GGT\], lipase, and serum amylase); urinalysis (proteinuria); coagulation (activated partial thromboplastin time prolonged, international normalized ratio \[INR\] increased). Grades of severity were defined by CTCAE v4.03. Grade 0 = No Change from normal or reference range (this grade is not included in the CTCAE v4.03 document but may used in certain circumstances). Grade 1 = mild adverse event (AE). Grade 2 = moderate AE; Grade 3 = severe AE. Grade 4 = life-threatening consequences; urgent intervention indicated. Grade 5 = death related to AE.

ORR was defined as percentage of participants with confirmed objective response (OR) of complete response (CR) and partial response (PR) based on RECIST version 1.1. CR was defined as complete disappearance of all target lesions with the exception of nodal disease. All target nodes must decrease to normal size (short axis \< 10 mm). All target lesions must be assessed. PR was defined as \>= 30% decrease under baseline of the sum of diameters of all target measurable lesions. The short diameter was used in the sum for target nodes, while the longest diameter was used in the sum for all other target lesions. All target lesions must be assessed.

All target lesions must be assessed. PR was defined as \>= 30% decrease under baseline of the sum of diameters of all target measurable lesions.
