A Study of Pembrolizumab (MK-3475) in Combination With Belzutifan (MK-6482) and Lenvatinib (MK-7902), or Pembrolizumab/Quavonlimab (MK-1308A) in Combination With Lenvatinib, Versus Pembrolizumab and Lenvatinib, for Treatment of Advanced Clear Cell Renal Cell Carcinoma (MK-6482-012)

An Open-label, Randomized Phase 3 Study to Evaluate Efficacy and Safety of Pembrolizumab (MK-3475) in Combination With Belzutifan (MK-6482) and Lenvatinib (MK-7902), or MK-1308A in Combination With Lenvatinib, Versus Pembrolizumab and Lenvatinib, as First-Line Treatment in Participants With Advanced Clear Cell Renal Cell Carcinoma (ccRCC)

Brief summary

The goal of this study is to evaluate the efficacy and safety of pembrolizumab plus belzutifan plus lenvatinib or pembrolizumab/quavonlimab plus lenvatinib versus pembrolizumab plus lenvatinib as first-line treatment in participants with advanced clear cell renal cell carcinoma (ccRCC). The primary hypotheses are (1) pembrolizumab plus belzutifan plus lenvatinib is superior to pembrolizumab plus lenvatinib with respect to progression-free survival (PFS) and overall survival (OS), in advanced ccRCC participants; and (2) pembrolizumab/quavonlimab plus lenvatinib is superior to pembrolizumab plus lenvatinib with respect to PFS and OS, in advanced ccRCC participants.

Inclusion criteria

* Has histologically confirmed diagnosis of RCC with clear cell component. * Has received no prior systemic therapy for advanced ccRCC * Male participants are abstinent from heterosexual intercourse or agree to use contraception during and for at least 7 days after last dose of study intervention with belzutifan and lenvatinib. * Female participants are not pregnant or breastfeeding and are either not a woman of child-bearing potential (WOCBP) or use a contraceptive method that is highly effective or are abstinent from heterosexual intercourse during the intervention period and for at least 120 days after pembrolizumab or pembrolizumab/quavonlimab or for at least 30 days after last dose of lenvatinib or belzutifan, whichever occurs last * Has adequately controlled blood pressure with or without antihypertensive medications * Has adequate organ function. * Participants receiving bone resorptive therapy must have therapy initiated at least 2 weeks prior to randomization/allocation

Design outcomes

Primary

MeasureTime frameDescription
Progression Free Survival (PFS) According to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) as Assessed by Blinded Independent Central Review (BICR)Up to approximately 46 monthsPFS is defined as the time from randomization to the first documented progressive disease (PD) 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. The appearance of one or more new lesions is also considered PD. PFS as assessed by BICR based on RECIST 1.1 will be presented.
Overall Survival (OS)Up to approximately 66 monthsOS is defined as the time from randomization to death due to any cause.

Secondary

MeasureTime frameDescription
Objective Response Rate (ORR) Per RECIST 1.1 as Assessed by BICRUp to approximately 46 monthsORR is defined as the percentage of participants who have 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) per RECIST 1.1. The percentage of participants who experience a CR or PR as assessed by BICR based on RECIST 1.1 will be presented.
Duration of Response (DOR) Per RECIST 1.1 as Assessed by BICRUp to approximately 66 monthsFor participants who demonstrate a confirmed CR (disappearance of all target lesions) or confirmed PR (at least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1, DOR is defined as the time from first documented evidence of CR or PR until PD or death due to any cause, whichever occurs first. Per RECIST 1.1, PD is defined as at least a 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. The appearance of one or more new lesions is also considered PD. The DOR as assessed by BICR based on RECIST 1.1 will be presented.
Number of Participants Who Experienced At least One Adverse Event (AE)Up to approximately 66 monthsAn 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 who experience at least one AE will be presented.
Number of Participants Who Discontinue Study Treatment Due to an AEUp to approximately 66 monthsAn 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 who discontinue study treatment due to an AE will be presented.
