lenvatinib plus pembrolizumablenvatinibParticipants receive lenvatinib 20 mg orally once a day (QD) plus pembrolizumab 200 mg by intravenous (IV) infusion on Day 1 of each 21-day cycle (Q3W). Pembrolizumab will be administered for up to 35 cycles (approximately 24 months). Lenvatinib will be administered until progressive disease or unacceptable toxicity.

Primary Outcome Measures
NameTimeMethod
Objective Response Rate (ORR)Up to approximately 55 months

ORR was defined as the percentage of participants in the analysis population who have a confirmed Complete Response (CR: disappearance of all lesions) or a Partial Response (PR: ≥30% decrease in the sum of target lesion diameters without progression in other lesions) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by Blinded Independent Central Review (BICR). Per protocol, RECIST 1.1 was modified to allow up to 10 target lesions total (up to 5 per organ).

Secondary Outcome Measures
NameTimeMethod
Progression-free Survival (PFS)Up to approximately 55 months

PFS was defined as the time from first day of study intervention to the first documented progressive disease (PD) per RECIST 1.1 by BICR, or death from any cause, whichever occurred first. Per protocol, RECIST 1.1 was modified to allow up to 10 target lesions total (up to 5 per organ). PFS was calculated using the nonparametric Kaplan-Meier method; participants who did not experience a PFS event were censored at the last disease assessment, or the last assessment before new anticancer treatment if new treatment was initiated.

Overall Survival (OS)Up to approximately 55 months

OS was defined as the time from the first day of study intervention to death due to any cause. Participants without documented death at the time of the final analysis were censored at the date of the last follow-up. OS was calculated using the nonparametric Kaplan-Meier method.

Duration of Response (DOR)Up to approximately 55 months

For participants who demonstrated a confirmed Complete Response (CR: disappearance of all lesions) or Partial Response (PR: ≥30% decrease in the sum of target lesion diameters without progression in other lesions) per RECIST 1.1, DOR was defined as the time from first documented CR or PR until progressive disease (PD) or death from any cause, whichever occurs first. Per protocol, RECIST 1.1 was modified to allow up to 10 target lesions total (up to 5 per organ). DOR was calculated using the nonparametric Kaplan-Meier method for censored data.

Area Under the Concentration Time Curve of Lenvatinib From Time 0 to Infinity (AUC 0-inf)Cycle 1 Day 1: 0.5 to 4 hours and 6 to 10 hours postdose; Cycle 1 Day 15: Predose and 2 to 12 hours postdose; Cycle 2 Day 1: Predose, 0.5 to 4 hours, and 6 to 10 hours post-dose (each cycle =21 days)

AUC0-inf was defined as the area under the concentration-time curve from time zero extrapolated to infinity. Plasma blood samples collected at specified timepoints, were used to estimate AUC0-inf following Lenvatinib and Pembrolizumab administration. Based on the lenvatinib plasma concentration data obtained on Cycle 1 Day 1, Cycle 1 Day 15, and Cycle 2 Day 1, a protocol specified population PK analysis was performed to characterize the steady state AUC0-inf of lenvatinib when co-administered with pembrolizumab.

Number of Participants Who Experience At Least One Adverse Event (AE)Up to approximately 55 months

An AE was 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 could therefore have been 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 experienced an AE is presented.

Number of Participants Who Discontinue Study Treatment Due to an AEUp to approximately 48 months

An AE was 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 could therefore have been 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 discontinued study treatment due to an AE is presented.
