INTRODUCTION: Despite improvements in treatment, survival rates of head and neck
squamous cell carcinoma (HNSCC) are stagnant. The existing chemotherapeutic
agents are non-selective and associated with toxicities. Combinations of the only
the US FDA-approved epidermal growth factor receptor (EGFR)-targeted agent,
cetuximab, with chemotherapy or radiation improves overall survival. However, the
response rates to cetuximab are modest. Thus, there is an urgent need for new
agents that can be safely integrated into current treatment regimens to improve
outcome. AREAS COVERED: Current EGFR-targeted drugs under clinical development
include mAbs and tyrosine kinase inhibitors. The modest efficacy of these drugs
implicates intrinsic or acquired resistance. Novel molecular agents inhibiting
alternative targets to overcome anti-EGFR resistance in HNSCC are under
investigation. Gene therapy and immunotherapy are also promising strategies to
improve efficacy and reduce toxicity. EXPERT OPINION: To date, only six drugs
have been FDA-approved for the treatment of head and neck cancer. Cetuximab is
the only approved molecular targeting agent for HNSCC and despite ubiquitous
expression of EGFR in HNSCC tumors, clinical responses are limited. Genetic and
epigenetic characterization of HNSCC tumors, coupled with improved preclinical
models, should facilitate the development of more effective drugs.
