title: Afatinib: A Review in Advanced Non-Small Cell Lung Cancer.
abstract: Afatinib (Giotrif®, Gilotrif®) is an orally administered, irreversible inhibitor of the ErbB family of tyrosine kinases. In the first-line treatment of patients with advanced lung adenocarcinoma with activating epidermal growth factor receptor (EGFR) mutations, afatinib significantly prolonged progression-free survival (PFS) and time to treatment failure (TTF), but not overall survival (OS), compared with gefitinib (LUX-Lung 7 trial). In the overall population of patients receiving first-line treatment for advanced lung adenocarcinoma with activating EGFR mutations, afatinib significantly prolonged PFS, but not OS, compared with pemetrexed plus cisplatin (LUX-Lung 3 trial) or gemcitabine plus cisplatin (LUX-Lung 6 trial). However, in both LUX-Lung 3 and LUX-Lung 6, OS was significantly prolonged in the subgroup of patients with deletions in exon 19 receiving afatinib versus chemotherapy. In the second-line treatment of advanced squamous non-small cell lung cancer (NSCLC), afatinib significantly prolonged PFS and OS, compared with erlotinib, regardless of EGFR mutation status (LUX-Lung 8 trial). Afatinib had a predictable and manageable tolerability profile in patients with advanced NSCLC. In conclusion, afatinib is an important option for the first-line treatment of patients with advanced NSCLC and activating EGFR mutations, and provides an additional option for the treatment of patients with squamous NSCLC that has progressed following first-line platinum-based chemotherapy.
