Abstract 4884

Background

Ceritinib is approved for the treatment of pts with metastatic ALK+ NSCLC. In previous studies (ASCEND-1 to 5), ceritinib was highly active in ALK+ NSCLC pts with reported intracranial responses in pts with measurable baseline brain lesions. ASCEND-7 (NCT02336451) was designed to specifically study intracranial effects of ceritinib and we report here efficacy and safety in pts with ALK+ NSCLC metastatic to the brain (Arms 1-4).

Methods

Eligible pts had, WHO performance status 0-2, ALK + (FISH) NSCLC, with active brain metastases (BM) either newly diagnosed or progressive, and ≥1 extracranial measurable lesion using RECIST v1.1. Pts may have been pretreated with chemotherapy and/or crizotinib (ALK inhibitor [ALKi]). Pts were assigned to arms 1 to 4 depending on prior treatment (refer to below table). Primary endpoint was investigator assessed whole body overall response rate (CR or PR) and key secondary endpoint was investigator assessed disease control rate (CR or PR or SD). Intracranial responses and extracranial responses were assessed using modified RECIST 1.1 and RECIST 1.1, respectively.

Results

As of 6-Feb-2019, 138 pts were treated in Arms 1-4 (Arm 1: 42; Arm 2: 40; Arm 3: 12; Arm 4: 44), and all the pts discontinued the treatment. Median follow-up for whole body progression free survival was 5.49 months across Arm 1-4. Efficacy endpoints by investigator assessment are reported in the below Table. Most common AEs (>50% all grades in any of the Arms 1-4) regardless of causality were diarrhoea, nausea, ALT increased, vomiting, AST increased, decreased appetite. Majority of these AEs was grade 1/2.Table:

*

In patients with measurable brain metastases at baseline. The usual criteria to select target lesions will be used but a maximum five target lesions located in the brain can be selected at baseline and evaluated at each assessment time point. L is the number of patients included in the duration of response analysis. M, number of patients with measurable brain metastases at baseline DCR, disease control rate; DOR, duration of response; NE, not estimable ORR, overall response rate; OS, overall survival; PFS, progression free survival; RECIST, Response Evaluation Criteria in Solid Tumors

Conclusions

Efficacy of ceritinib, either in pts with or without a prior exposure to crizotinib, as reported in other studies, is confirmed in this study where only pts with active brain metastases were eligible. Safety profile of ceritinib in these pts remain consistent to what was reported earlier.
