Title Number of Participants Experiencing Dose-Limiting Toxicities (DLTs) According to National Cancer Institute Common Terminology Criteria for Adverse Events Version 4.0 (NCI-CTCAE v.4.0) in Participants With Solid Tumors (Parts A and A1)
Hide Description DLTs were assessed according to NCI-CTCAE v.4.0 during the first cycle (28 days) and were defined as occurrence of any of the following toxicities if judged by the investigator to be possibly, probably or definitely related to study drug administration: Grade (Gr) 4 nonhematologic toxicity; Gr 4 hematologic toxicity lasting ≥14 days; Gr 3 nonhematologic toxicity lasting >3 days despite optimal supportive care; any Grade 3 non-hematologic laboratory value if medical intervention was required to treat the participant, the abnormality led to hospitalization, or the abnormality persisted for >1 week; Gr 3 or 4 febrile neutropenia; thrombocytopenia <25,000 cells/mm^3 (if associated with a bleeding event requiring an elective platelet transfusion, or a life-threatening bleeding event which resulted in urgent intervention and admission to an Intensive Care Unit); or Gr 5 toxicity. The number of participants in Part A and Part A1 with a DLT were reported by pembrolizumab dose received.
Time Frame Up to 28 days in Cycle 1
Hide Outcome Measure Data
Hide Analysis Population Description
All participants in Parts A and A1 who received ≥1 dose of study treatment and either 1) had a DLT in Cycle 1 or 2) received ≥90% of the prescribed dose of pembrolizumab in Cycle 1 and completed all safety evaluations ≥28 days after the first administration of pembrolizumab without experiencing DLT. Per protocol, Parts A2 and B-F were not analyzed.

Hide Description An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the Sponsor's product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition which was temporally associated with the use of the Sponsor's product was also an AE. The number of participants who experienced an AE was reported for each arm.

Title Maximum Change From Baseline (CFB) in Tumor Size Assessed by IRC Per RECIST 1.1 According to Programmed Death-Ligand 1 (PD-L1) Immunohistochemical (IHC) Expression Status in Ipilimumab (Ipi)-Exposed and Ipi-Naive Melanoma Participants (Parts B Plus D)
Hide Description The percent change from baseline in tumor size based on IRC per RECIST 1.1 was reported according to PD-L1 status in Ipi-Exposed and Ipi-Naïve melanoma participants. Tumor PD-L1 status was measured by the tumor proportion score (TPS), which was the percentage of tumor cells identified using IHC analysis that expressed PD-L1. Tumors with ≥1% positive staining for PD-L1 were considered positive. Maximum tumor change was defined as the percent change of the participant's smallest post-baseline tumor size from the baseline. The number of participants in a percent change from baseline range was reported categorically according to PD-L1 status (PD-L1-Positive, PD-L1 Negative, PD-L1 Status Unknown). Negative percent change from baseline values indicate tumor size reduction, with the greatest reduction possible indicated as "≤ -30%". As specified by the protocol, this analysis of melanoma participants was performed according to ipilimumab exposure (Ipi-Exposed and Ipi-Naïve).

Title Maximum Change From Baseline (CFB) in Tumor Size Assessed by IRC Per RECIST 1.1 According to PD-L1 IHC Expression Status in Prior Treatment (TRT)-Naïve and Previously-Treated NSCLC Participants (Parts C Plus F)
Hide Description Percent CFB in tumor size based on IRC per RECIST 1.1 was reported according to PD-L1 status in prior treatment-naïve and previously-treated NSCLC participants. Tumor PD-L1 status was measured by TPS, which was the percentage of tumor cells identified using IHC analysis that expressed PD-L1, as follows: TPS ≥50% =tumor strongly positive, TPS of 1%-49% =tumor weakly positive, TPS <1% =tumor considered negative, or TPS unknown. Maximum tumor change for a participant was defined as the percent change of the participant's smallest post-baseline tumor size from baseline. The number of participants in a percent CFB range was reported categorically according to PD-L1 status (TPS ≥50%, TPS = 1-49%, TPS <1%, TPS Unknown). Negative percent CFB values indicate tumor size reduction, with the greatest reduction possible indicated as "≤ -30%". As specified by the protocol, analysis of NSCLC participants was performed according to prior treatment exposure (Treatment Naive and Previously Treated).

Adverse Event Reporting Description All-Cause Mortality reported for all randomized/enrolled participants. AEs reported for All Treated Population.Per protocol, disease progression on study not considered an AE unless related to drug. Thus, MedDRA preferred terms "Neoplasm progression", "Malignant neoplasm progression" and "Disease progression" unrelated to drug excluded as AEs. 5 participants were not assessed by cutoff and were followed to study completion; end of study assessments are missing for these 5 and status is unknown
