Registration Number
NCT06212752
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

This study is to assess the pharmacokinetics (PK) and safety of SC MK-3475A vs intravenous (IV) pembrolizumab, administered with chemotherapy in first line treatment of adult Japanese participants with metastatic non-small cell lung cancer. The primary hypotheses of this study are MK-3475A subcutaneous (SC) is noninferior to pembrolizumab IV with respect to ...

Detailed Description

Japan extension study will require approximately six years which includes one additional year (beyond the global study's last participant last study related contact) from the time the first participant (or their legally acceptable representative) provides informed consent until the last participant's last study related contact to complete.

Primary Outcome Measures
NameTimeMethod
Objective Response Rate (ORR)Up to ~72 months

ORR was defined as the percentage of participants who have a confirmed 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) per RECIST 1.1 as assessed by BICR.

Secondary Outcome Measures
NameTimeMethod
Area Under the Curve (AUC) of Pembrolizumab Measured After the First DoseAt designated time points (Up to ~14 months)

AUC is defined as area under curve exposure. Blood samples collected pre-dose and at multiple timepoints post-dose will be used to determine AUC.

Trough Concentration (Ctrough) of Pembrolizumab Measured at Steady StateAt designated time points (Up to ~18 months)

Ctrough is defined as the trough concentration at steady-state. Blood samples collected pre-dose and at multiple timepoints post-dose will be used to determine Ctrough.

Maximum Serum Concentration (Cmax) of Pembrolizumab Measured After the First DoseAt designated time points (Up to ~28 months)

Cmax is defined as the peak concentration over the dosing interval. Blood samples collected pre-dose and at multiple timepoints post-dose will be used to determine Cmax.

Trough Concentration (Ctrough) of Pembrolizumab Measured After the First DoseAt designated time points (Up to ~28 months)

Ctrough is defined as the trough concentration. Blood samples collected pre-dose and at multiple timepoints post-dose will be used to determine Ctrough.

OS is defined as the time from randomization to death due to any cause.

Duration of Response (DOR) per Response Evaluation Criteria In Solid Tumors Version 1.1 (RECIST 1.1)Up to ~72 months

For participants who show confirmed CR or PR, DOR is defined as the time from the first documented evidence of CR or PR until disease progression or death due to any cause, whichever occurs first.

Number of Participants Who Experienced at Least One Adverse Event (AE)Up to~28 months

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. The number of participants with an AE will be reported for Arms 1 and 2.
