“The FDA has granted a priority review to a supplemental new drug application (sNDA) for afatinib (Gilotrif) for the frontline treatment of patients with metastatic non–small cell lung cancer (NSCLC) whose tumors harbor EGFR exon 21 (L861Q), G719X, or S768I substitution mutations.
“Uncommon mutations such as these represent less than 10% of the EGFR mutations found in NSCLC patients, but are associated with poor prognosis and survival, Boehringer Ingelheim, the manufacturer of afatinib, noted in a press release.”

“Erlotinib showed promise as neoadjuvant therapy in patients with epidermal growth factor receptor (EGFR) mutant stage IIIA-N2 non-small-cell lung cancer (NSCLC) who demonstrated good disease control with tolerable toxicity following treatment.
“Dr Baohui Han, Pulmonary Department, Shanghai Chest Hospital, Shanghai, China presented findings from a single arm, phase II clinical trial during the New Treatment Avenues Proffered Papers session at the European Lung Cancer Conference, 15 to 18 April 2015 in Geneva, Switzerland. The trial aimed to evaluate efficacy and safety of erlotinib as neoadjuvant treatment in patients with stage IIIA-N2 NSCLC and activating EGFR mutation.
“The trial’s primary endpoint was radical resection rate. Secondary endpoints included pathological complete response rate (pCR), objective response rate (ORR), disease free survival (DFS), overall survival (OS), safety profile, and explorative biomarkers.
“This study screened 155 patients and subsequently enrolled 44 patients with stage IIIA N2 NSCLC and 25 patients with IIIA N2 NSCLC plus activating EGFR (exon 19 or 21) mutations. All patients had ECOG performance status 1 and had been previously untreated for stage IIIA-N2 NSCLC, that was confirmed by endobronchial ultrasound.”
