Study of Pembrolizumab (MK-3475) in Participants With Advanced Non-small Cell Lung Cancer (MK-3475-025/KEYNOTE-025)
April 29, 2020 updated by: Merck Sharp & Dohme LLC
An Open-label, Non-randomized, Multi-center Phase Ib Study of MK-3475 in Subjects With PD-L1 Positive Advanced Non-small Cell Lung Cancer
This study is being done to evaluate the safety and efficacy of pembrolizumab (MK-3475) in participants with advanced non-small cell lung cancer (NSCLC) tumors that are positive for programmed cell death ligand 1 (PD-L1): the hypothesis is that treatment with pembrolizumab will result in a clinically meaningful Overall Response Rate (ORR).

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Overall Response Rate (ORR) by Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) in Strongly PD-L1 Positive Participants
Time Frame: Up to 2 years
|
On-study imaging was to be performed every 9 weeks after the first dose of study drug, or more frequently if clinically indicated.
ORR was defined as the percentage of participants in the analysis population who had a Complete Response (CR; disappearance of all target lesions) or Partial Response (PR; at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters).
The percentage of strongly PD-L1 positive participants who experienced a CR or PR is presented.
|
Up to 2 years
|
Number of Participants Experiencing Adverse Events (AEs)
Time Frame: Up to 27 months (Up to 90 days after last dose of study drug)
|
An AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which did not necessarily have to have a causal relationship with this treatment.
An AE was any unfavorable and unintended sign (including an abnormal laboratory finding), 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 (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 the study drug, was also an AE.
After discontinuation of study drug, each participant was monitored for a minimum of 30 days for AE monitoring (serious AEs were monitored for up to 90 days after last dose of study drug).
The number of participants who experienced an AE is presented.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Progression Free Survival (PFS) by RECIST 1.1 in Strongly PD-L1 Positive Participants
Time Frame: Up to 2 years
|
PFS was defined as the time from the first day of study treatment to the first documented disease progression per RECIST 1.1 based on blinded independent central radiologists' review or death due to any cause, whichever occurred first.
Using RECIST 1.1, progressive disease was defined as either a 20% relative increase in the sum of diameters of target lesions, taking as reference the smallest sum on study OR an absolute increase of >5 mm in the sum of lesions, OR the appearance of new lesions.
PFS was analyzed using the Kaplan-Meier method and is reported in months.
The median PFS for all strongly PD-L1 positive participants is presented.
|
Up to 2 years
|
Duration of Response (DOR) by RECIST 1.1 in Strongly PD-L1 Positive Participants
Time Frame: Up to 2 years
|
DOR was measured from the time measurement criteria were first met for CR/PR (whichever was first recorded) until the first date that recurrent or progressive disease was objectively documented (taking as reference for progressive disease the smallest measurements recorded on study).
DOR was censored at the last tumor assessment date if a responder did not have PD or death.
Non-responders were not included in the analysis.
The lower and upper limits were estimated at the time of data cutoff.
DOR was analyzed using the Kaplan-Meier method and is reported in days.
The median DOR for all strongly PD-L1 positive participants with a confirmed response is presented.
