In the pivotal ASCEND-1 study, ceritinib showed whole body efficacy in ALKi-naïve pts with ALK+ NSCLC (including those with baseline BM), most of whom had received multiple prior therapies; median progression-free survival (mPFS) was 18.4 mo. The ASCEND-3 single-arm, open-label multicentre study evaluated the efficacy and safety of ceritinib in previously treated ALKi-naïve pts with ALK+ NSCLC (NCT01685138).
Pts enrolled worldwide received oral ceritinib 750 mg/d (fasted) from 21 Jan 2013. Whole body efficacy was assessed by investigator (inv) and by Blinded Independent Review Committee (BIRC). Prior chemotherapy (≤3 lines) was permitted. Data cutoff was 15 Nov 2015.
Of 124 pts receiving ceritinib, 122 (98.4%) had received prior antineoplastic regimens (with 31 [25%] receiving ≥3). Of the 124 pts, 49 (39.5%) had baseline BM. Median time from diagnosis to initiation of ceritinib was 13.5 mo (range 1.0–283.1); median duration of exposure was 22.5 mo (range 0.1–32.8); median follow-up was 23.1 mo (range 0.6–32.8). mPFS was 16.6 mo (95% CI 11.0, 22.1) by inv, and 18.4 mo (95% CI 10.9, 26.3) by BIRC. The table shows efficacy in all pts, and in pts by baseline BM status. The most frequently reported AEs were gastrointestinal (GI): diarrhoea (85.5%), nausea (77.4%) and vomiting (71.8%). Most GI AEs were Grade 1/2. Grade 3/4 diarrhoea, nausea and vomiting occurred in 3.2%, 6.5% and 6.5% of pts, respectively. Overall, 11.3% of pts discontinued due to AEs, with no particular AE predominating.
Consistent with ASCEND-1, ceritinib resulted in a durable mPFS of 16.6/18.4 mo by inv/BIRC in ALKi-naïve pts with ALK+ NSCLC, of whom 54.8% had received ≥2 prior antineoplastic regimens. Whole body response rates were robust, irrespective of the presence of baseline BM. No new safety signals were identified in this study.
