“…Rather, these data suggest that targeting EGFR alone is probably not sufficient, especially in a ligand rich environment of advanced disease, and that patient population selection is important (Harrington et al, 2013;Wilson et al, 2011). For example, although lapatinib, a dual TKI of both EGFR and HER2, was not effective either as a monotherapy in R/M SCCHN (de Souza et al, 2012) or as an adjuvant therapy for postsurgical patients with high risk (Harrington et al, 2014), it did demonstrate promise in HPV (human papillomavirus) negative treatment naive patients with unresectable stage III/IVA-B SCCHN (Harrington et al, 2013) -based on which, lapatinib is currently being evaluated in HPV negative SCCHN in combination with CCRT (concurrent chemoradiation therapy) (RTOG 3501). Similarly, afatinib, a TKI for pan-HER members, was recently shown in a phase II study to be able to achieve comparable disease control rate (50%) to cetuximab (56.5%) in R/M SCCHN whose disease has progressed after platinum-containing therapy (Seiwert et al, 2014).…”
