Brief Summary

The goal of this research study is to learn which therapy order (adding pembrolizumab during vs. after cisplatin and radiation) may be more effective in treating head and neck cancer, as well as learn the side effects of these combinations. Pembrolizumab is an immune therapy, a drug that stimulates the immune system to fight cancer, and is FDA approved in lung cancer and melanoma.

Detailed Description

The study regimen consists of cisplatin and radiation for all patients, the standard treatment for head and neck cancer. All patients will also receive pembrolizumab (the study drug), and will be randomized to two treatment schedules: either pembrolizumab with cisplatin-radiation, or pembrolizumab after completing cisplatin-radiation.

Conditions

Head and Neck Squamous Cell Carcinoma

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

• Unknown primary: p16(+) AND one of the following
• ≥ N2a AND ≥ 10 pack-years tobacco exposure
• N3 disease irrespective of tobacco exposure
