Trial Summary

What is the purpose of this trial?

This is a study of pembrolizumab (MK-3475) with or without lenvatinib (E7080/MK-7902) as a first line intervention in a PD-L1 selected population with participants with recurrent or metastatic head and neck squamous cell carcinoma. Hypotheses include: * Pembrolizumab + lenvatinib is superior to pembrolizumab + placebo with respect to Objective Response Rate (ORR) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by blinded independent central review (BICR). * Pembrolizumab + lenvatinib is superior to pembrolizumab + placebo with respect to Progression Free Survival (PFS) per RECIST 1.1 as assessed by BICR. * Pembrolizumab + lenvatinib is superior to pembrolizumab + placebo with respect to overall survival (OS).

Treatment Details

Interventions

• Lenvatinib
• Pembrolizumab
• Placebo

Trial Overview The study tests if combining Pembrolizumab with Lenvatinib improves response rates, slows disease progression, and extends survival compared to Pembrolizumab with a placebo. Participants will either receive both drugs or one drug plus a placebo without knowing which group they're in.

Participant Groups

Group I: Pembrolizumab with Lenvatinib Experimental Treatment 2 Interventions

Participants 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.

Group II: Pembrolizumab with Placebo Active Control 2 Interventions

Participants receive lenvatinib-matching placebo 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).
