- Progression-Free Survival (PFS) Per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 as Assessed by Blinded Central Imaging [ Time Frame: Through Database Cutoff Date of 20-May-2019 (Up to approximately 31.2 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, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. Note: The appearance of one or more new lesions was also considered PD. The PFS per RECIST 1.1 is presented.
- Overall Survival (OS) [ Time Frame: Through Database Cutoff Date of 20-May-2019 (Up to approximately 31.2 months) ]
OS was defined as the time from randomization to death due to any cause. Participants without documented death at the time of the analysis were censored at the date of the last follow-up. The OS is presented.

PFS is defined as the time from randomization to the first documented progressive disease (PD) per RECIST 1.1 based on BICR or death due to any cause, whichever occurs first. Per RECIST 1.1, PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. Note: The appearance of one or more new lesions is also considered PD. PFS, as assessed by blinded central imaging, will be presented.
- Overall Survival (OS) [ Time Frame: Up to 24 months ]
OS is defined as the time from randomization to death due to any cause. The percentage of surviving participants will be presented.

- Overall Response Rate (ORR) Per RECIST 1.1 as Assessed by Blinded Central Imaging [ Time Frame: Through Database Cutoff Date of 20-May-2019 (Up to approximately 31.2 months) ]
ORR was defined as the percentage of participants in the analysis population 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, taking as reference the baseline sum diameters) per RECIST 1.1. The percentage of participants who experienced a CR or PR is presented.
- Duration of Response (DOR) Per RECIST 1.1 as Assessed by Blinded Central Imaging [ Time Frame: From time of first documented evidence of CR or PR through database cutoff date of 20-May-2019 (Up to approximately 31.2 months) ]
For participants who demonstrated a confirmed CR (disappearance of all target lesions) or PR (≥30% decrease in the sum of diameters of target lesions) per RECIST 1.1, DOR was defined as the time from first documented evidence of a CR or PR until PD or death. DOR for participants who had not progressed or died at the time of analysis was censored at the date of their last tumor assessment. 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. Note: The appearance of one or more new lesions was also considered PD. DOR assessments were based on blinded central imaging review with confirmation. The DOR per RECIST 1.1 for all participants who experienced a confirmed CR or PR is presented.
- Number of Participants Who Experienced an Adverse Event (AE) [ Time Frame: Through Database Cutoff Date of 20-May-2019 (Up to approximately 31.2 months) ]

- Number of Participants Who Discontinued Any Study Drug Due to an AE [ Time Frame: Up to approximately 24 months ]
The number of participants who discontinued any randomized study drug due to an AE is presented.

DOR as assessed by blinded central imaging will be presented.
- Number of Participants Who Experience an Adverse Event (AE) [ Time Frame: Up to 27 months ]
An AE is defined as any untoward medical occurrence in a participant administered study treatment which does not necessarily have to have a causal relationship with this treatment. The number of participants who experience an AE will be presented.
- Number of Participants Who Discontinue Study Treatment Due to an AE [ Time Frame: Up to 24 months ]

Per irRECIST, irPD was confirmed if any of the following are observed in 2 scans performed at least 4 weeks apart: target lesion sum of diameters remains ≥20 % and at least 5 mm absolute increase compared to nadir; non-target disease resulting in initial PD is qualitatively worse; new lesion resulting in initial irPD is qualitatively worse; additional new lesion(s) since last evaluation; or additional new non-target lesion progression since last evaluation.

Study of Pemetrexed+Platinum Chemotherapy With or Without Pembrolizumab (MK-3475) in Participants With First Line Metastatic Nonsquamous Non-small Cell Lung Cancer (MK-3475-189/KEYNOTE-189)-Japan Extension Study
|
A Randomized, Double-Blind, Phase III Study of Platinum+Pemetrexed Chemotherapy With or Without Pembrolizumab (MK-3475) in First Line Metastatic Non-squamous Non-small Cell Lung Cancer Subjects (KEYNOTE-189)
|
This is a Japan Extension Study of Global Study MK-3475-189 (NCT02578680). This is an efficacy and safety study of pembrolizumab (MK-3475) combined with pemetrexed/platinum chemotherapy versus pemetrexed/platinum chemotherapy alone in adult Japanese participants with advanced or metastatic nonsquamous non-small cell lung cancer (NSCLC) who have not previously received systemic therapy for advanced disease. Participants will be randomly assigned to receive pembrolizumab combined with pemetrexed/platinum (Investigators choice of cisplatin or carboplatin), OR pemetrexed/platinum (Investigators choice of cisplatin or carboplatin).
With Amendment 11 (effective date 31-Jan-2022), once the study objectives have been met or the study has ended, participants will be discontinued from this study and will be enrolled in an extension study to continue protocol-defined assessments and treatment.
The primary hypothesis is that pembrolizumab in combination with pemetrexed/platinum chemotherapy prolongs Progression-Free Survival (PFS) and Overall Survival (OS) compared to pemetrexed/platinum chemotherapy alone.
|
The MK-3475-189-Japan Extension Study will be identical to the global study (e.g. inclusion and exclusion criteria, study primary and secondary outcome measures and study procedures).
The MK-3475-189-Japanese Extension Study enrolled a total of 30 participants and the analyses included 10 participants (pembrolizumab =4; control = 6) that had been previously enrolled in the MK-3475-189 global study (NCT02578680), resulting in a total of 40 participants.
