Safety and Efficacy Study of Pembrolizumab (MK-3475) Combined With Lenvatinib (MK-7902/E7080) as First-line Intervention in Adults With Advance Melanoma (MK-7902-003/E7080-G000-312/LEAP-003)

NCT03820986

Description:

The purpose of this study is to assess the safety and efficacy of pembrolizumab (MK-3475) combined with lenvatinib (MK-7902/E7080) compared to pembrolizumab alone (with placebo for lenvatinib) as first-line treatment in adults with no prior systemic therapy for their advanced melanoma. The primary study hypotheses are that: 1) The combination of pembrolizumab and lenvatinib is superior to pembrolizumab and placebo as assessed by Progression-free Survival (PFS) per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1), and 2) The combination of pembrolizumab and lenvatinib is superior to pembrolizumab and placebo as assessed by Overall Survival (OS). For this study, RECIST 1.1 has been modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ.

Primary Outcome Measures

Measure:Progression-free Survival (PFS) as Assessed by Modified Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1)
Time Frame:Up to approximately 2 years
Safety Issue:
Description:PFS is defined as the time from date of randomization to the date of the first documentation of progressive disease (PD) or death from 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. For this study, RECIST 1.1 has been modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ. PFS as assessed by modified RECIST 1.1 will be presented.

Secondary Outcome Measures

Measure:Objective Response Rate (ORR) as Assessed by Modified Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1)
Time Frame:Up to approximately 2 years
Safety Issue:
Description:ORR is defined as the percentage of participants in the analysis population who have a Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: At least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1. For this study, RECIST 1.1 has been modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ. ORR as assessed by modified RECIST 1.1 will be presented.
Measure:Duration of Response (DOR) as Assessed by Modified Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1)
Time Frame:Up to approximately 2 years
Safety Issue:
Description:For participants who demonstrated CR (disappearance of all target lesions) or PR (at least a 30% decrease in the sum of diameters of target lesions), DOR is defined as the date of the first documented evidence of CR or PR until PD or death from 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. For this study, RECIST 1.1 has been modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ. DOR as assessed by modified RECIST 1.1 will be presented.
Measure:Number of Participants with Adverse Events (AEs)

Measure:Number of Participants Who Discontinue Study Treatment Due to Adverse Events (AEs)
Time Frame:Up to approximately 2 years
Safety Issue:
Description:The number of participants who discontinue study treatment due to an AE will be presented.

Time Frame:Baseline (Cycle 1 Day 1: Predose) and at designated time points: Predose; each cycle is 21 days (Up to approximately 2 years)
Safety Issue:
Description:The EORTC QLQ-C30 is a questionnaire to assess the overall quality of life of cancer patients. The PF Score consists of participant responses to questions regarding PF (5 questions about daily activities [strenuous activities, long walks, short walks, bed/chair rest and needing help with eating, dressing, washing themselves or using the toilet]. For PF, responses range in score from 0 to 100, with a higher score indicating a better outcome. The change from Baseline in PF Score will be presented.

The GHS Score consists of participant responses to questions regarding GHS (How would you rate your overall health during the past week?). For GHS, responses range in score from 0 to 100, with a higher score indicating a better outcome. TTD, based on a ≥10-point negative change (decrease) from Baseline in GHS Score will be presented.
