ListOutcomeTime frameDescription
PrimaryNumber of Participants Experiencing Adverse Events (AEs)
Serious AEs: Up to 90 days after last dose of treatment (Up to 28 months); nonserious AEs: Up to 30 days after last dose of treatment (Up to 26 months) - through final analysis (FA) cutoff date 26 Apr 2016 (Cohorts: A, B, B2, D) & 01 Sep 2015 (Cohort C)
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 unfavorable 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. The number of participants who experienced at least one AE was presented for the first course pembrolizumab treatment per protocol.
PrimaryNumber of Participants Discontinuing From Study Treatment Due to an AEUp to last dose of study treatment (Up to approximately 25 months) - through FA cutoff date 26 Apr 2016 (Cohorts: A, B, B2, D) & 01 Sep 2015 (Cohort C)
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.
PrimaryOverall Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) Response Rate Based on Blinded Independent Central Radiology (BICR) Review (Cohorts A, B, C, and D)Every 8 weeks until disease progression (Cohorts A, B, D: Up to ~ 35 months; Cohort C: Up to ~ 28 months) - through FA cutoff date 26 Apr 2016 (Cohorts: A, B, D) & 01 Sep 2015 (Cohort C)
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.
PrimaryOverall RECIST 1.1 Response Rate Based on BICR Review for Participants in Cohort B2Every 8 weeks until disease progression (Up to ~ 35 months) - through FA cutoff date 26 Apr 2016
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.
SecondaryOverall RECIST 1.1 Response Rate Based on BICR Review, Cohorts B and B2 Human Papilloma Virus (HPV)-Positive ParticipantsEvery 8 weeks until disease progression (Up to ~ 35 months) - through FA cutoff date 26 Apr 2016
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 had tumors which were HPV positive and who experienced a CR or PR in the combined Cohorts B2 and B2 was presented for the first course of pembrolizumab treatment per protocol.
SecondaryOverall RECIST 1.1 Response Rate Based on BICR Review, Cohort D Asia-Pacific (AP) ParticipantsEvery 8 weeks until disease progression (Up to ~ 35 months) - through FA cutoff date 26 Apr 2016
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 were from the Asia Pacific region and experienced a CR or PR in Cohort D was presented for the first course of pembrolizumab treatment per protocol.
SecondaryOverall RECIST 1.1 Response Rate Based on BICR Review, for Participants Previously Treated With Cetuximab and Platinum in Cohorts B and B2Every 8 weeks until disease progression (Up to ~ 35 months) - through FA cutoff date 26 Apr 2016
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 were previously treated with cetuximab and platinum and experienced a CR or PR in the Cohorts B and B2 was presented for the first course of pembrolizumab treatment per protocol.
SecondaryOverall RECIST 1.1 Response Rate Based on Investigator Assessment for Cohorts A, B, C and DEvery 8 weeks until disease progression (Cohorts A, B, D: Up to ~ 35 months; Cohort C: Up to ~ 28 months) - through FA cutoff date 26 Apr 2016 (Cohorts: A, B, D) & 01 Sep 2015 (Cohort C)
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 by Investigator evaluation. The percentage of participants who experienced a CR or PR in Cohorts A, B, C and D based on investigator assessment was presented for the first course of pembrolizumab treatment per protocol. ORR per RECIST 1.1 based on investigator assessment was presented for Cohort B2 in a separate outcome measure.
SecondaryOverall RECIST 1.1 Response Rate Based on Investigator Assessment for Cohort B2Every 8 weeks until disease progression (Up to ~ 35 months) - through FA cutoff date 26 Apr 2016
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 by Investigator evaluation. The percentage of participants who experienced a CR or PR in Cohort B2 based on investigator assessment was presented for the first course of pembrolizumab treatment per protocol. ORR per RECIST 1.1 based on investigator assessment was presented for the other cohorts in a separate outcome measure.
OtherNumber of Participants With Log Fold Change From Baseline in Cytokines (Interleukin 10 [IL-10]) >1Baseline and Week 8
IL-10 is an anti-inflammatory cytokine. The number of participants with a log fold change from Baseline in IL-10 \>1 was to be presented. Protocol Amendment 03 (26 May 2015) removed the secondary objective of investigating the relationship between programmed cell death 1 (PD-1) inhibition and up-regulation of cytokines biomarkers predicting response (e.g. IL-10) from the protocol. No data were collected for this outcome measure.
