Afatinib Improves Progression-Free Survival vs Erlotinib in Second-Line Treatment of Advanced Squamous Cell Carcinoma of the Lung

“In the phase III LUX-Lung 8 trial reported in The Lancet Oncology, Soria et al found that the irreversible ErbB-family inhibitor afatinib (Gilotrif) significantly improved progression-free and overall survival vs the EGFR tyrosine kinase inhibitor erlotinib as second-line treatment in patients with stage IIIB or IV squamous cell carcinoma of the lung who had disease progression after four or more cycles of platinum-based chemotherapy.

“In this open-label trial, 795 patients from 23 countries were randomly assigned between March 2012 and January 2014 to receive afatinib at 40 mg/d (n =398) or erlotinib at 150 mg/d (n = 397). The primary endpoint was progression-free survival on independent central review in the intent-to-treat population…

“The investigators concluded: ‘The significant improvements in progression-free survival and overall survival with afatinib compared with erlotinib, along with a manageable safety profile and the convenience of oral administration suggest that afatinib could be an additional option for the treatment of patients with squamous cell carcinoma of the lung.’ “
