Immunotherapy agents began being investigated for the treatment of head and neck cancer about 2 to 3 years ago, Burtness explains. Results of the Keystone-012 trial, which examined pembrolizumab in patients with HPV-positive/HPV-negative disease, demonstrated an overall response rate (ORR) of 25%. Evidence suggests that if PD-L1 or PD-L2 expression is present, ORR may be higher. There are now ongoing phase III trials examining the agent in platinum-refractory disease and as a first-line therapy compared with chemotherapy.
Ongoing trials are also investigating MEDI4736, which has demonstrated a 50% ORR in a subset of PD-L1 positive patients. MEDI4736 is also being examined in combination with tremelimumab. Finally, results of a phase III trial looking at nivolumab in patients with platinum-refractory disease can be expected some time in 2016.
