Brief summary
This is an open-label Phase 1b/2 trial of lenvatinib (E7080) plus pembrolizumab in participants with selected solid tumors. Phase 1b will determine and confirm the maximum tolerated dose (MTD) for lenvatinib in combination with 200 milligrams (mg) (intravenous \[IV\], every 3 weeks \[Q3W\]) pembrolizumab in participants with selected solid tumors (i.e. non-small cell lung cancer, renal cell carcinoma, endometrial carcinoma, urothelial carcinoma, squamous cell carcinoma of the head and neck, melanoma or leiomyosarcoma). Phase 2 (Expansion) will evaluate the safety and efficacy of the combination in 7 cohorts at the MTD from Phase 1b (lenvatinib 20 mg/day orally + pembrolizumab 200 mg Q3W, IV).

Inclusion criteria
1. Phase 1b: Histologically and/or cytologically confirmed metastatic selected solid tumor types that have progressed after treatment with approved therapies or for which there are no standard effective therapies available. If nivolumab or pembrolizumab is an approved therapy for the participant's tumor type, but the participant has not been treated with it, the Investigator may enroll the participant in this study. Phase 2: Histologically and/or cytologically confirmed metastatic selected solid tumor types with 0-2 prior lines of systemic therapy. If previously treated, participant has progressed after previous treatment. For the non-small cell lung cancer (NSCLC) and melanoma cohorts, participants must have progressed on or after prior treatment with one anti-programmed cell death protein 1 (anti-PD-1), anti-PD-1 ligand 1 (anti-PD-L1), or anti-PD-1 ligand 2 (anti-PD-L2) agent. For the renal cell carcinoma (RCC) cohort, participants must have progressed on treatment with an anti- programmed death receptor-1 /programmed death receptor-ligand 1 monoclonal antibody (anti-PD-1/PD-L1 mAb) administered either as monotherapy, or in combination with other checkpoint inhibitors or other therapies, the regimen with an anti-PD-1/PD-L1 mAb must be the most recent therapy.

Objective Response Rate (ORR) Based on Immune-related Response Evaluation Criteria in Solid Tumors (irRECIST) Version 1.1 at Week 24
ORR was defined as the percentage of participants whose best overall response (BOR) was immune related complete response (irCR) or immune related partial response (irPR) based on investigator assessment according to irRECIST version 1.1. irCR was defined as disappearance of all target lesions. Any pathological lymph nodes (target or non-target) had to be reduced in short axis to less than (\<) 10 millimeter (mm). irPR was defined as at least a 30% decrease in sum of diameters of target lesions, taking as reference the baseline sum of diameters.

Secondary
Progression-free Survival (PFS) Based on irRECIST Version 1.1
PFS was defined as the time from the first dose date to the date of irPD or date of death (whichever occurred first) according to irRECIST version 1.1. irPD was defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this included the baseline sum if that was the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions was also considered progression).
Time frame: From date of first dose of study drug administration to date of irPD or date of death, whichever occurred first (up to 73 months)
Population: The FAS included all participants who entered the study treatment period.
