These data support the rationale for the development of monalizumab:

Preclinical data will be presented in a mini-symposium and show NKG2A expression on tumor-infiltrating CD8+ T cells in patients with head and neck cancer as well as synergy between treatment with a HPV vaccine and NKG2A blockade in a mouse tumor model;
During a poster session, safety data from the dose-escalation part of a Phase Ib/II study evaluating monalizumab in combination with cetuximab in patients with recurrent or metastatic squamous cell carcinoma of the head and neck will be presented. In this study, monalizumab plus cetuximab were well tolerated with no additional safety concerns compared to monalizumab or cetuximab alone.
Monalizumab is currently being tested in five Phase I and I/II clinical trials in various cancer as a single agent and in combination with other therapies.
