Pivotal Trial

Summary

This trial is studying whether giving pembrolizumab with or without lenvatinib to people with cancer of the head and neck who have PD-L1 selection is better than giving pembrolizumab with placebo.

Who is the study for?

This trial is for adults with recurrent or metastatic head and neck squamous cell carcinoma that can't be cured by surgery or radiation. They must have good organ function, not be pregnant or breastfeeding, agree to use contraception, and have a certain level of physical ability (ECOG score 0-1). People who've had recent major surgery, live vaccines, other cancer treatments like pembrolizumab or similar drugs in the past are excluded.

What is being tested?

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.

What are the potential side effects?

Pembrolizumab may cause immune system-related side effects such as inflammation of organs; skin reactions; liver issues; hormonal gland problems like thyroid disorders; and lung issues like pneumonitis. Lenvatinib might cause high blood pressure, fatigue, nausea, decreased appetite among others.

Experimental Treatment

Active Control

Group I: Pembrolizumab with LenvatinibExperimental Treatment2 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 PlaceboActive Control2 Interventions
