    Research Summary

    Head and neck cancer describes a range of tumours in the head and neck area, which includes the cavity of mouth and nose, pharynx, larynx, sinuses, thyroid, and salivary glands. Over 600,000 cases of head and neck cancer occur annually worldwide. Although the head and neck region contains many structures and types of cells, most head and neck cancers start from the lining of the upper respiratory and digestive tract and mainly begin in cells called squamous cells. Around 50% of head and neck squamous cell carcinomas (HNSCC) are diagnosed at a locally advanced stage (where the cancer has spread adjacently). The 5-year survival rate for HNSCC remains low.

    Programmed cell death 1 (PD1) is a protein present on the surface of immune (attacking) cells which fight cancer. When immune cells meet cancer cells, PD1 becomes activated by programmed cell death ligands 1 and 2 (PDL1 and PDL2) which are proteins on the surface of cancer cells. The activated immune cells become exhausted or die thus stopping them from attacking the cancer. The study drug pembrolizumab has been developed to block PD1/PDL1 interaction, thereby increasing the immune attack on cancers.

    This phase III study will last approximately 6 years (1 year treatment; 5 years follow-up) and will recruit approximately 780 men and women over the age of 18 with locally advanced HNSCC.

    The purpose of the study is to evaluate the safety and effectiveness of pembrolizumab given with chemoradiation (a combination of chemotherapy and radiotherapy) and as a maintenance therapy versus placebo with chemoradiation. Participants will be assigned randomly in a 1:1 ratio to one of the two arms of trial. Participants may receive treatment for up to 1 year.

    The study is funded by Merck Sharp & Dohme Limited and will take place at 8 study centres in UK.
