ListOutcomeTime frameDescription
PrimaryOverall Survival (OS) in Participants With Squamous Cell Carcinoma (SCC) of the EsophagusThrough Final Analysis data cutoff date of 15-Oct-2018 (up to approximately 34 months)OS was defined as the time from randomization to death due to any cause. Median OS in participants with SCC of the esophagus is presented.
PrimaryOverall Survival (OS) in Participants With Programmed Death-Ligand 1 Combined Positive Score ≥10 (PD-L1 CPS ≥10)Through Final Analysis data cutoff date of 15-Oct-2018 (up to approximately 34 months)OS was defined as the time from randomization to death due to any cause. Median OS in participants with a PD-L1 CPS ≥10 is presented.
PrimaryOverall Survival (OS) in All ParticipantsThrough Final Analysis data cutoff date of 15-Oct-2018 (up to approximately 34 months)OS was defined as the time from randomization to death due to any cause. Median OS in all participants is presented.
SecondaryProgression-free Survival (PFS) as Assessed by Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) in All ParticipantsThrough Final Analysis data cutoff date of 15-Oct-2018 (up to approximately 34 months)
PFS was defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurred first. Per RECIST 1.1, PD was defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also have demonstrated an absolute increase of ≥5 mm. The appearance of ≥1 new lesions was also considered PD. Median PFS as assessed by blinded independent central review per RECIST 1.1 in all participants is presented.
SecondaryObjective Response Rate (ORR) as Assessed by Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) in All ParticipantsThrough Final Analysis data cutoff date of 15-Oct-2018 (up to approximately 34 months)
ORR was defined as the percentage of participants who had a Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: ≥30% decrease in the sum of diameters of target lesions) as assessed using RECIST 1.1. The percentage of all participants who experienced a CR or PR is presented.
SecondaryProgression-free Survival (PFS) as Assessed by Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) in Participants With Squamous Cell Carcinoma (SCC) of the EsophagusThrough Final Analysis data cutoff date of 15-Oct-2018 (up to approximately 34 months)
PFS was defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurred first. Per RECIST 1.1, PD was defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also have demonstrated an absolute increase of ≥5 mm. The appearance of ≥1 new lesions was also considered PD. Median PFS as assessed by blinded independent central review per RECIST 1.1 is presented for participants with SCC of the esophagus.

ORR was defined as the percentage of participants who had a Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: ≥30% decrease in the sum of diameters of target lesions) as assessed using RECIST 1.1. The percentage of participants with SCC of the esophagus who experienced a CR or PR is presented.
Secondary
Objective Response Rate (ORR) as Assessed by Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) in Participants With Programmed Death-Ligand 1 Combined Positive Score ≥10 (PD-L1 CPS ≥10)
Through Final Analysis data cutoff date of 15-Oct-2018 (up to approximately 34 months)
ORR was defined as the percentage of participants who had a Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: ≥30% decrease in the sum of diameters of target lesions) as assessed using RECIST 1.1. The percentage of participants with a PD-L1 CPS ≥10 who experienced a CR or PR is presented.
SecondaryNumber of Participants Experiencing an Adverse Event (AE)Through End-of-Trial Analysis data cutoff date of 14-Mar-2022 (up to approximately 6 years)
An AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE could therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a pre-existing condition that was temporally associated with the use of the Sponsor's product was also an AE. The number of participants who experienced ≥1 AE is presented.
