Cohort 1 was evaluated statistically by comparing the ORR for pembrolizumab to a fixed efficacy target of 10% using a binomial exact test. The percentage of participants with CR and PR as assessed by the investigator is presented.

ORR was defined as the percentage of the participants with either a stringent complete response (sCR), complete response (CR), very good partial response (VGPR), or partial response (PR) according to the International Myeloma Working Group (IMWG) 2006 response criteria. CR=negative immunofixation of serum and urine+disappearance of soft tissue plasmacytomas+≤5% plasma cells in the bone marrow (BM); sCR=stringent complete response, CR as above+normal serum free light-chain ratio and absence of clonal cells in BM; VGPR=serum+urine M-protein (M-p) by immunofixation but not on electrophoresis OR ≥ 90% reduction in serum M-p+urine M-p \<100 mg/24 hr; PR=≥50% reduction of serum M-p+reduction in 24-hour urine M-p by ≥90% or to \<200 mg/24 hours. Cohort 2 was evaluated statistically by comparing the ORR for pembrolizumab to a fixed efficacy target of 25% using a binomial exact test. The percentage of participants with CR, sCR, PR, VGPR as assessed by the investigator is presented.

CRR was defined as the percentage of participants with complete remission according to the revised response criteria for malignant lymphoma per Cheson et al. 2007. Complete remission was demonstrated by disappearance of all evidence of disease in the bone marrow, spleen, liver, and lymph nodes. Cohort 3 was evaluated statistically by comparing the complete remission for pembrolizumab to a fixed efficacy target of 10% using a binomial exact test. The percentage of participants with complete remission as assessed by the investigator is presented.

ORR was defined as the percentage of participants with response (complete response \[CR\] or partial response \[PR\]) according to the revised response criteria for malignant lymphoma per Cheson et al. 2007. CR was demonstrated by disappearance of all evidence of disease in the bone marrow, spleen, liver, and lymph nodes. PR was \>50% decrease in the sum of product diameters (SPD) for ≤6 target masses for lymph nodes and \>50% decrease in SPD for a single nodule in greatest transverse diameter for spleen and liver, and no size increase in the lymph nodes, spleen, or liver. The pooled Cohort 4 sub-cohorts were evaluated statistically by comparing the ORR for pembrolizumab to a fixed efficacy target of 25% using a binomial exact test. The percentage of participants with CR and PR as assessed by the investigator is presented.

ORR was evaluated for each of the Cohort 4 sub-cohorts: 4A (primary mediastinal B-cell lymphoma), 4B (grey zone, splenic marginal zone, and mantle cell lymphomas), 4C (follicular lymphoma), and 4D (diffuse large B-Cell lymphoma). ORR was defined as the percentage of participants with response (complete response \[CR\] or partial response \[PR\]) according to the revised response criteria for malignant lymphoma per Cheson et al. 2007. CR was demonstrated by disappearance of all evidence of disease in the bone marrow, spleen, liver, and lymph nodes. PR was \>50% decrease in the sum of product diameters (SPD) for ≤6 target masses for lymph nodes and \>50% decrease in SPD for a single nodule in greatest transverse diameter for spleen and liver, and no size increase in the lymph nodes, spleen, or liver. Per protocol, Cohorts 4A, 4B, 4C, and 4D were not planned to be compared to an efficacy target. The percentage of participants with CR and PR as assessed by the investigator is presented.

PR was \>50% decrease in the sum of product diameters (SPD) for ≤6 target masses for lymph nodes and \>50% decrease in SPD for a single nodule in greatest transverse diameter for spleen and liver, and no size increase in the lymph nodes, spleen, or liver. Per protocol, pooled Cohort 5 was not planned to be evaluated statistically compared to a fixed efficacy target. The percentage of participants with CR and PR as assessed by the investigator is presented.

An AE was defined as any untoward medical occurrence in a participant administered a study treatment which did not necessarily have to have a causal relationship with this treatment. An AE could be any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of study treatment, whether or not considered related to the study treatment. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition that was temporally associated with the use of study treatment, was also an AE. Some cases of clinical progression that led to discontinuation of study treatment were captured as AEs that led to discontinuation of study treatment. The number of participants who discontinued study treatment due to an AE was presented for the first course pembrolizumab treatment per protocol.

Overall Response Rate (ORR) was defined as the percentage of participants who experienced a Complete Response (CR; disappearance of all target lesions) or a Partial Response (PR; at least a 30% decrease in the sum of diameters of target lesions) and was assessed using RECIST 1.1 based on BICR evaluation. The percentage of participants who experienced a CR or PR for Cohorts A, B, C and D participants was presented for the first course of pembrolizumab treatment per protocol. Cohorts A, B, C and D enrolled participants with programmed cell death-ligand 1 (PD-L1) positive tumors.

ORR was defined as the percentage of participants in the analysis population who experienced a CR (disappearance of all target lesions) or a PR (at least a 30% decrease in the sum of diameters of target lesions) and was assessed using RECIST 1.1 based on BICR evaluation. The percentage of participants who experienced a CR or PR in Cohort B2 was presented for the first course of pembrolizumab treatment per protocol.

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.

ORR was defined as the percentage of participants in the analysis population who had a confirmed Complete Response (CR: disappearance of all lesions) or Partial Response (PR: at least a 30% decrease in the sum of diameters \[SOD\] of target lesions, taking as reference the baseline SOD) according to RECIST 1.1, which was modified for this study to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ. The percentage of participants who experienced a confirmed CR or PR according to RECIST 1.1 as assessed by IRO was reported as the ORR for each melanoma dose arm (Parts B plus D).

ORR was defined as the percentage of participants in the analysis population who had a confirmed CR (disappearance of all lesions) or PR (at least a 30% decrease in the sum of diameters \[SOD\] of target lesions, taking as reference the baseline SOD) according to RECIST 1.1, which was modified for this study to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ. The percentage of participants who experienced a confirmed CR or PR according to RECIST 1.1 as assessed by IRC was reported as the ORR for each NSCLC dose arm (Parts C plus F).
