In both ASCEND-1 and ASCEND-2 studies, ceritinib demonstrated durable responses and promising PFS in pts with ALK+ NSCLC pre-treated with chemotherapy and crizotinib. ASCEND-6 (NCT02040870) evaluated pharmacokinetics (PK), safety and efficacy of ceritinib in Chinese pts with ALK+ NSCLC who had progressive disease during or after crizotinib (irrespective of prior chemo [≤2]).


A total of 103 pts were enrolled, of which, 20 pts completed 5-day PK run-in period (phase I; single dose of ceritinib 750mg [fasted]) followed by 120 hrs of PK sampling before starting continuous daily dosing; all other pts started on continuous daily dosing ceritinib 750mg fasted (28 day cycles). Primary endpoint: PK, safety and tolerability. Key secondary endpoint: investigator-assessed ORR and other secondary endpoints: DOR, DCR, OIRR and PFS per RECIST 1.1. Data cut off: 30 Oct 2015.


Of 103 pts: median age (range) was 49 (26–76) yrs; 53.4% were male; 92.2% had WHO PS ≤ 1; 69.9% pts received ≥1 line of prior chemo; 63.1% had brain metastases at baseline; and crizotinib was the last treatment before enrollment for all pts. Median duration of exposure and follow-up time were 7.06 (0–18.8) and 8.3 (0.1–18.6) mos, respectively. Median Tmax (n = 16) was ∼ 6 hrs; Geometric means of AUC0-24h (n = 16) and Cmax (n = 16) at steady-state were 22000 ng*h/mL, and 1080 ng/mL, respectively.rn

Most common AEs regardless of study drug relationship (mostly grade 1/2): diarrhea (72.8%) vomiting (61.2%), increased ALT (58.3%), increased AST (57.3%), and nausea (55.3%). AEs leading to discontinuation reported in 12.6%.



PK profile of ceritinib in Chinese pts was comparable to multinational phase 1 study (ASCEND-1). Consistent with ASCEND-1 and ASCEND-2 studies, ceritinib demonstrated clinical activity and manageable safety in Chinese pts with ALK+ NSCLC having previously treated with chemotherapy and crizotinib.
