Current Primary Outcome Measures (submitted: February 26, 2021)

Overall Survival (OS) [ Time Frame: Up to approximately 40 months ]

OS is defined as the time from randomization to the time of death from any cause. OS will be presented.

• Original Primary Outcome Measures: Same as current

Current Secondary Outcome Measures (submitted: April 21, 2021)

• Progression Free Survival (PFS) According to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) [ Time Frame: Up to approximately 40 months ]
  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 modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ, 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. PFS as assessed per modified RECIST 1.1 will be presented.
• Objective Response Rate (ORR) According to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) [ Time Frame: Up to approximately 40 months ]
  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, modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ. ORR as assessed per modified RECIST 1.1 will be presented.
• Duration of Response (DOR) According to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) [ Time Frame: Up to approximately 40 months ]
  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 time from the first documented evidence of CR or PR until PD or death from any cause, whichever occurs first. Per RECIST 1.1 modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ, or death from any cause, 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. DOR as assessed per modified RECIST 1.1 will be presented.
• Number of Participants Who Experience an Adverse Event (AE) [ Time Frame: Up to approximately 40 months ]
  An adverse event is defined as 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. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The number of participants who experience one or more adverse events will be presented.
• Number of Participants Who Discontinue Study Treatment Due to an Adverse Event (AE) [ Time Frame: Up to approximately 40 months ]
  An adverse event is defined as 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. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The number of participants who discontinue study treatment due to an adverse event will be presented.

  The EORTC QLQ-C30 is a cancer specific health-related quality-of life (QoL) questionnaire. Participant responses to the questions regarding Global Health Status (GHS; "How would you rate your overall health during the past week?") and Quality of Life (QoL; "How would you rate your overall quality of life during the past week?") are scored on a 7-point scale (1= Very poor to 7=Excellent). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. The change from baseline in GHS (EORTC QLQ-C30 Item 29) and QoL (EORTC QLQ-C30 Item 30) combined score will be presented. A higher score indicates a better outcome.

For this item, individual responses to the question "Have you lacked appetite?" are given on a 4-point scale (1=Not at all; 4=Very much). Scores are transformed to a range from 0-100, with a lower score indicating a better outcome. The change from baseline in the EORTC QLQ-C30 appetite loss (Item 13) scale score will be presented.

  The EORTC QLQ-CR29 is a health-related quality-of life (QoL) questionnaire specific for colorectal cancer, including a single-item scale score for bloating (QLQ-CR29 Item 37). For this item, individual responses to the question "Did you have a bloated feeling in your abdomen?" are given on a 4-point scale (1=Not at all; 4=Very much). Scores are transformed to a range from 0-100, with a lower score indicating a better outcome. The change from baseline in the EORTC QLQ-CR29 bloating (Item 37) scale score will be presented.

• Official Title: A Phase 3 Randomized Study of Lenvatinib in Combination With Pembrolizumab Versus Standard of Care in Participants With Metastatic Colorectal Cancer Who Have Received and Progressed On or After or Became Intolerant to Prior Treatment

Brief Summary

The purpose of this study is to assess the safety and efficacy of lenvatinib (MK-7902/E7080) in combination with pembrolizumab (MK-3475) in participants with metastatic colorectal cancer. The study will also compare lenvatinib plus pembrolizumab with the standard of care treatment of regorafenib and TAS-102 (trifluridine and tipiracil hydrochloride).

The primary study hypothesis is that lenvatinib plus pembrolizumab is superior to standard of care with respect to overall survival.
