Primary

MeasureTime frame
Main Objective: 1. To evaluate and compare PFS per RECIST 1.1 as assessed by BICR in subjects. treated with pembrolizumab plus axitinib versus sunitinib monotherapy. 2. To evaluate and compare OS in subjects treated with pembrolizumab plus axitinib versus sunitinib monotherapy.;Secondary Objective: 1. To compare ORR and DCR per RECIST 1.1 as assessed by BICR in subjects treated with a combination of pembrolizumab plus axitinib versus sunitinib monotherapy. DOR will also be evaluated. 2. To evaluate PFS rate per RECIST 1.1 as assessed by BICR at 12, 18, and 24 months based on data adequacy; to evaluate OS rates at 12, 18, and 24 months based on data adequacy. 3. To evaluate and compare safety and tolerability profiles in subjects treated with pembrolizumab plus axitinib versus sunitinib monotherapy. 4. To compare time to deterioration (TTD) based on the Functional Assessment of Cancer Therapy Kidney Symptom Index—Disease-Related Symptoms (FKSI-DRS) scale in subjects treated with pembrolizumab plus axitinib versus sunitinib monotherapy. 5. To assess the longitudinal score changes from baseline to 42 weeks as measured by European Organization for the Research and Treatment of Cancer (EORTC) QLQ-C30 global health status/quality of life scale.;Primary end point(s): - Progression Free Survival (PFS) per RECIST 1.1 as assessed by BICR - Overall Survival (OS);Timepoint(s) of evaluation of this end point: First Interim Analysis (IA1) Performed after enrollment completion, once a 7-mo minimum follow up has been achieved and a minimum of 305 PFS events have accrued. Expected to be 22 mo after the first sbj randomized. Approximately 48% of final required OS events (or 195 deaths) are expected at that time. Purpose: First IA for PFS and OS. Second Interim Analysis (IA2) Performed when approximately 74% of the final required OS events (or 299 deaths) have accrued, expected to be 31 mo after study start. At IA2, approximately 487 PFS events are expected. Purpose: Final analysis

Secondary

MeasureTime frame
Secondary end point(s): •Objective Response Rate (ORR) – RECIST 1.1 by BICR Objective response rate is defined as the proportion of the subjects in the analysis population who have a CR or PR per RECIST 1.1. •Duration of Response (DOR) - RECIST 1.1 by BICR For subjects who demonstrate CR or PR, DOR is defined as the time from first documented evidence of CR or PR per RECIST 1.1 until disease progression per RECIST 1.1 or death due to any cause, whichever occurs first. See Section 8.6.1 for the censoring rules. •Disease Control Rate (DCR) - RECIST 1.1 by BICR Disease control rate is defined as the percentage of subjects who have achieved CR, PR, SD of = 6 months based on assessments by BICR per RECIST 1.1. •Safety endpoints: The following safety parameters will be analyzed: AEs and SAEs graded per NCI CTCAE, Version 4.0 criteria with time to onset/recovery, causality and outcome; changes in laboratory values, vital signs since baseline, treatment discontinuations and reason for discontinuation, death and cause of death, etc. Concomitant medications will be collected with time and reasons for use. •Health-Related Quality of Life Endpoints: FKSI-DRS, EORTC-QLQ-C30, and EuroQol EQ-5D-3L questionnaires. As of end of January 2020, PRO data will no longer be collected.;Timepoint(s) of evaluation of this end point: Imaging after randomization will be performed at Week 12 (84 days ±7 days), then Q6W (42 days ±7 days) through Week 54, then Q12W (84 days ±7 days) thereafter until PD is BICR verified or further confirmed by the investigator. Imaging visit window may be ± 14 days after Week 104. Unscheduled imaging can be performed as clinically indicated. The timing of imaging assessments should follow calendar days from randomization and should not be adjusted for dose delays or cycle starts. Safety and Health-Related Quality of Life assessments are cycle based. The DMC has responsibility for assessment of overall risk: benefit. The DMC will review safety periodically (every
