P3.02a-036 - Phase 1 Study of Ceritinib 450 mg or 600 mg Taken with a Low-Fat Meal versus 750 mg in Fasted State in ALK+ Metastatic NSCLC (ID 7170)
14:30 - 14:30 | Author(s): A. Bearz
The anaplastic lymphoma kinase (ALK) inhibitor ceritinib is approved at 750 mg fasted for the treatment of patients with ALK-rearranged (ALK+) metastatic non-small cell lung cancer (NSCLC) pretreated with crizotinib. The pharmacokinetic (PK) part of this study (Part 1) compares PK exposure of ceritinib following food consumption versus a fasted state in advanced ALK+ NSCLC patients.
Part 1 of this prospective, open-label, multicenter, randomized, 3-arm, phase 1 study (ASCEND-8; NCT02299505) is investigating PK and safety of ceritinib in advanced ALK+ NSCLC patients, treatment-naïve or pretreated with multiple lines of chemotherapy and/or crizotinib. Here, we compare steady-state PK of ceritinib 450 or 600 mg taken with a low‑fat meal versus ceritinib 750 mg fasted (primary endpoint) and report preliminary safety outcomes from Part 1. Part 2 continues to randomize treatment-naïve patients and will assess safety and efficacy.
As of June 16, 2016 (data cut-off), 137 patients were randomized in a 1:1:1 ratio to each treatment arm; 135 patients received one dose (safety set) and 97 patients had evaluable steady-state PK data. Disease characteristics were comparable between arms. Median follow-up duration was 4.14 months (range, 0.1–13.9). Relative to 750 mg fasted, the 450 mg fed arm demonstrated comparable steady-state PK, while the 600 mg fed arm showed ~25% higher steady-state PK (Table). Preliminary safety data suggests overall frequency of AEs and types of AEs were comparable between arms. However, incidences of gastrointestinal (GI)-related AEs (diarrhea, nausea or vomiting) were lowest, with no grade 3/4 GI AEs reported, in the 450 mg fed arm.Figure 1
Steady-state PK was comparable in advanced ALK+ NSCLC patients taking ceritinib 450 mg with a low-fat meal versus 750 mg fasted. This study continues to enroll treatment-naïve patients into Part 2 to assess efficacy across the three treatment arms and assess longer safety follow-up.
