Ensartinib (X-396) is a novel ALK inhibitor with high activity against a broad range of crizotinib-resistant ALK mutations (such as G1269A, F1174, C1156Y, and T1151) and CNS metastases. This Phase I study (NCT02959619) determined the maximum tolerated dose (MTD) and recommended Phase II dose (RP2D), investigated the safety and PK, and explored the clinical efficiency for the compound as monotherapy in Chinese ALK+ NSCLC patients.Patients with advanced ALK+ NSCLC were treated with oral ensartinib (150, 200, 225, or 250 mg once daily) using a conventional 3+3 dose escalation design. The dose-escalation evaluated patients in 28-day cycles. In the dose-expansion phase, ensartinib was given at the recommended dose to further explore PK and clinical efficacy. Treatment was continued until disease progression, or unacceptable toxicity. The study finds ensartinib was well tolerated in Chinese ALK-positive NSCLC patients with high antitumor activity. RP2D was established at 225 mg QD. Ensartini..... READ ARTICLE

Background: TQ-B3101 is a novel compound, which deacetylated metabolite targets to receptor tyrosine kinases including ALK, ROS1 and MET. Preclinical studies showed TQ-B3101 had a better Inhibition activity and duration compared with equimolar crizotinib... Conclusions: TQ-B3101 was well tolerated and showed preliminary antitumor activity in ALK+, ROS1+ and MET amplification pts. Recommended phase II dose (RP2D) might be 300mg BID according longtime safety data. Further anti-tumor research in pts with ROS1+ is under going as multicenter clinical study in China. (NCT03972189).
