Abstract
Introduction Alectinib demonstrated clinical efficacy and an acceptable safety profile in two phase II studies (NP28761 and NP28673). Here we report the pooled efficacy and safety data after 15 and 18 months more follow-up than in the respective primary analyses. Methods Enrolled patients had ALK receptor tyrosine kinase gene (ALK)-positive NSCLC and had progressed while taking, or could not tolerate, crizotinib. Patients received oral alectinib, 600 mg twice daily. The primary end point in both studies was objective response rate assessed by an independent review committee (IRC) using the Response Evaluation Criteria in Solid Tumors, version 1.1. Secondary end points included disease control rate, duration of response, progression-free survival, overall survival, and safety. Results The pooled data set included 225 patients (n = 138 in NP28673 and n = 87 in NP28761). The response-evaluable population included 189 patients (84% [n = 122 in NP28673 and n = 67 in NP28761]). In the response-evaluable population, objective response rate as assessed by the IRC was 51.3% (95% confidence interval [CI]: 44.0–58.6 [all PRs]), the disease control rate was 78.8% (95% CI: 72.3–84.4), and the median duration of response was 14.9 months (95% CI: 11.1–20.4) after 58% of events. Median progression-free survival as assessed by the IRC was 8.3 months (95% CI: 7.0–11.3) and median overall survival was 26.0 months (95% CI: 21.4–not estimable). Grade 3 or higher adverse events (AEs) occurred in 40% of patients, 6% of patients had treatment withdrawn on account of AEs, and 33% had AEs leading to dose interruptions/modification. Conclusions This pooled data analysis confirmed the robust systemic efficacy of alectinib in ALK-positive NSCLC with a durable response rate. Alectinib also had an acceptable safety profile with a longer duration of follow-up. ? 2017 International Association for the Study of Lung Cancer
