Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Complete Response (CR) at the End of Study Intervention as Assessed by Independent Central Review (ICR) Per Lugano 2014 Response Criteria	The percentage of participants who have CR at the end of study intervention, after the completion of pembrolizumab consolidation, as assessed by ICR per Lugano 2014 response criteria will be presented.	Up to approximately 57 weeks
Secondary	CR at the End of Study Intervention as Assessed by Investigator Per Lugano 2014 Response Criteria	The percentage of participants who have CR at the end of study intervention, after the completion of pembrolizumab consolidation, as assessed by the investigator per Lugano 2014 response criteria will be presented.	Up to approximately 57 weeks
Secondary	Duration of Complete Response (DurCR) as Assessed by Independent Central Review Per Lugano 2014 Response Criteria	DurCR is defined, only for the subgroup of participants who achieve CR, as the time from the first documentation of CR to disease progression or to death due to any cause, whichever comes first as assessed by the independent central review per Lugano 2014 response criteria.	Up to approximately 72 months
Secondary	Positron Emission Tomography (PET) Negativity by Independent Central Review Per 3-Fluorodeoxyglucose (FDG)-PET 5-point Scale After Administration of Pembrolizumab Monotherapy	The rate of PET negativity is defined as the percentage of participants with a score of 1, 2, or 3, assessed by independent central review according to the FDG-PET 5-point scale, after administration of pembrolizumab monotherapy. Per FDG-PET 5-point scale: Score 1= No uptake above the background, Score 2= Uptake = mediastinum, Score 3= Uptake > mediastinum but = liver, Score 4= Uptake moderately higher than liver, Score 5= Uptake markedly higher than liver or new lesions. In the present study, scores of 1, 2 and 3 are considered to be negative and scores of 4 and 5 are considered to be positive.	Up to approximately 9 weeks
Secondary	PET Negativity by Independent Central Review Per FDG-PET 5-point Scale After Administration of Pembrolizumab Monotherapy and Chemotherapy	The rate of PET negativity is defined as the percentage of participants with a score of 1, 2, or 3, assessed by independent central review according to the FDG-PET 5-point scale, after administration of pembrolizumab monotherapy and chemotherapy. Per FDG-PET 5-point scale: Score 1= No uptake above the background, Score 2= Uptake = mediastinum, Score 3= Uptake > mediastinum but = liver, Score 4= Uptake moderately higher than liver, Score 5= Uptake markedly higher than liver or new lesions. In the present study, scores of 1, 2 and 3 are considered to be negative and scores of 4 and 5 are considered to be positive.	Up to approximately 17 weeks
Secondary	Number of Participants Who Experienced an Adverse Event (AE)	An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The number of participants who experienced an AE will be reported.	Up to approximately 64 weeks
Secondary	Number of Participants Who Discontinued Study Treatment Due to an AE	An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The number of participants who discontinue study treatment due to an AE will be reported.	Up to approximately 57 weeks
