P2.04-003 Phase II Trial of X-396 (Ensartinib) for Chinese Patients with ALK (+) Non–Small-Cell Lung Cancer Who Progressed on Crizotinib

Abstract

Crizotinib has been established as the standard first-line treatment for patients with ALK-rearranged non-small-cell lung cancer. However, despite its superiority to chemotherapy, resistance occurs within approximately 12 months. New ALK-inhibitors are needed to overcome the resistance to crizotinib and to increase drug penetration to CNS. X-396 (ensartinib) is a novel, potent ALK tyrosine kinase inhibitor (TKI). Its phase I/II study showed X-396 is well-tolerated with favorable anti-tumor activities in both ALK TKI-naïve and crizotinib-resistant NSCLC patients, as well as patients with CNS metastases.
