摘要:
Some Anaplastic lymphoma kinase (ALK) inhibitors with good inhibition of ROS1 in preclinical studies has been reported possibly beneficial in ROS1-positive non-small cell lung cancer (NSCLC). In this work, we studied the efficacy and safety of ensartinib in the treatment of patients with ROS1-positive NSCLC.The exploratory study was a phase II single-arm, multicenter design (NCT03608007). ROS1-positive NSCLC patients with a prior chemotherapy line number of ≤1 who received ensartinib at the dose of 225 mg once daily were enrolled. The primary endpoint was objective response rate (ORR) evaluated by investigator per Response Evaluation Criteria in Solid Tumors version 1.1.From June 2018 to July 2019, 59 patients were enrolled at 23 centers in China. At the time of data cutoff, the median follow-up was 19.8 months (range 0.8-22.5). The median ORR was 27.0% (95 % CI 13.8, 44.1) with 10 partial responses. Median duration of response (DoR) was 4.8 months (95% CI 1.8-10.8). The median progression-free survival (PFS) was 4.6 months (95% CI 4.0-6.4). The median overall survival (OS) was not estimable (95% CI 14.9-not estimable). Of 4 patients with brain metastases, intracranial disease control was reported in 3 (75.0%; 95% CI 19.4-99.4). The most common treatment-related adverse events (TRAEs) were rash and liver enzyme abnormalities, with good prognosis after adjustment for dosage and concomitant medication. The most of TRAEs were grade 1-2, and incidence of grade ≥3 TRAEs was 25.4%.Ensartinib had a moderset efficacy in patients with ROS1-positive NSCLC with an acceptable safety profile.Copyright © 2021.
