X-396 (Ensartinib) is a novel, potent anaplastic lymphoma kinase (ALK) small molecule tyrosine kinase inhibitor (TKI) with additional activity against MET, ABL, Axl, EPHA2, LTK, ROS1 and SLK. Ensartinib has demonstrated activity in ALK treatment naïve and previously treated patients and has a generally well tolerated safety profile. Ensartinib is currently in a global phase 3 trial in ALK positive non-small cell lung cancer (NSCLC) patients. The phase 1/2 clinical findings support the preclinical results that the use of ensartinib may result in favorable therapeutic outcomes in patients with ALK NSCLC, including patients with CNS metastases. In this study, ensartinib was generally well tolerated with the most common adverse event being a rash.

CNS Activity

Curator's Comment: Preclinical data demonstrated that X-396 penetrates the blood-brain barrier in mice.

Sample Use Guides

Eligible patients with ALK+ NSCLC will receive oral X-396 (ensartinib) at 225mg QD with or without food until progression or unacceptable toxicity develops
Route of Administration: Oral
X-396 inhibited endogenous ALK phosphorylation and potential downstream signaling pathways in H3122 lung cancer cells harboring the EML4-ALK E13;A20 fusion at low concentrations of drug (100-1000 nM).
