Introduction: The phase II, single-arm ASCEND-3 study assessed the efficacy and safety of ceritinib in anaplastic lymphoma kinase (ALK) inhibitor (ALKi)–naive patients with ALK-rearranged NSCLC who had received at least three previous lines of chemotherapy. Here, we report the final efficacy and safety results. Methods: Eligible patients (including those with asymptomatic or neurologically stable brain metastases) received oral ceritinib (750 mg/day, fasted). The primary end point was investigator-assessed overall response rate (ORR). Secondary end points were Blinded Independent Review Committee–assessed ORR; investigator- and Blinded Independent Review Committee–assessed overall intracranial response rate, duration of response, time to response, disease control rate, and progression-free survival (PFS); overall survival (OS); and safety. Exploratory end points included patient-reported outcomes. Results: Of the 124 patients enrolled, 122 (98.4%) had received previous antineoplastic medications (31 patients [25.0%] received at least three regimens), and 49 (39.5%) had baseline brain metastases. The median follow-up time (data cutoff: January 22, 2018) was 52.1 (range, 48.4–60.1) months. The investigator-assessed ORR was 67.7% (95% confidence interval [CI]: 58.8–75.9), and the median PFS was 16.6 months (95% CI: 11.0–23.2). The median OS was 51.3 months (95% CI: 42.7–55.3). Most common adverse events (all grades, ≥60% of patients, all-causality) were diarrhea (85.5%), nausea (78.2%), and vomiting (71.8%). Overall, 18 patients (14.5%) had an adverse event leading to treatment discontinuation. Health-related quality of life was maintained during ceritinib treatment. Conclusions: Ceritinib exhibited prolonged and clinically meaningful OS, PFS, and duration of response in chemotherapy-pretreated (at least three lines), ALKi-naive patients with ALK+ NSCLC. The safety profile was consistent with that reported in previous studies.

The primary end point was investigator-assessed overall response rate (ORR). Secondary end points were Blinded Independent Review Committee–assessed ORR; investigator- and Blinded Independent Review Committee–assessed overall intracranial response rate, duration of response, time to response, disease control rate, and progression-free survival (PFS); overall survival (OS); and safety.
