Non-small-cell lung cancer (NSCLC) comprises 85%–90% of lung cancer diagnoses and despite advances in multimodality therapies, 5-year survival rates remain dismal with a median survival for patients with metastatic disease of 1 year. The positive outcomes of targeted therapies against the kinase domain of epidermal growth factor receptor in NSCLC triggered consistent efforts to identify the so-called driver mutations as other potential targets. Anaplastic large-cell kinase (ALK) gene rearrangements were identified and targeted resulting in promising response rates in early studies. Unfortunately, most of the patients treated with crizotinib, the first-generation ALK inhibitor, progressed within 9 months. Ceritinib is a second-generation ALK inhibitor that has demonstrated activity in crizotinib-resistant patients, becoming a promising treatment option in this population. Furthermore, additional novel ALK inhibitors and agents targeting alternative pathways have been recruited to rechallenge this evasive disease post-crizotinib resistance. Keywords: crizotinib, EML4-ALK rearrangement, Vysis, ALK inhibitor
