Abstract 1348P

Background

Previous report from the ASCEND-8 (NCT02299505) trial showed consistent efficacy of ceritinib 450 mg-fed vs 750 mg-fasted with less gastrointestinal (GI) toxicity in pts with anaplastic lymphoma kinase-rearranged (ALK+) advanced/metastatic NSCLC (Cho BC, et al 2019 JTO). Here, we report results from Asian pts in the ASCEND-8 trial.

Methods

Key efficacy endpoints were blinded independent review committee (BIRC)-assessed overall response rate (ORR) and duration of response (DOR) evaluated per RECIST v1.1. Other endpoints were investigator-assessed ORR and DOR; BIRC- and investigator-assessed progression-free survival (PFS) and disease control rate (DCR); overall survival (OS) and safety per CTCAE v4.03.

Results

As of the final data cut-off date (March 6, 2020), 198 treatment-naïve pts were included in the efficacy analysis, of which 74 (37% of the full analysis set) comprised the Asian subset; 450 mg-fed (n=29), 600 mg-fed (n=19) and 750 mg-fasted (n=26). Baseline characteristics were mostly comparable across study arms. At baseline, more pts in the 450 mg-fed arm had brain metastasis vs 750 mg-fasted arm (44.8% vs 26.9%). Efficacy results in Asian pts are shown in the table. Per BIRC, pts in the 450 mg-fed arm had numerically higher ORR, median DOR, 24-month DOR rate, median PFS, and 24-month PFS rate vs 750 mg-fasted arm, with overlapping confidence intervals (CI). The 36-month OS rate was 93.1% in the 450 mg-fed arm vs 70.9% in the 750-mg fasted arm. Any grade GI toxicity (group event for nausea, diarrhea and vomiting) occurred in 82.8%, 78.9% and 96.2% pts in 450 mg-fed, 600 mg-fed and 750 mg-fasted arms, respectively. Grade 3/4 GI toxicity occurred in 1 (3.4%) patient in the 450 mg-fed arm, 1 (5.3%) patient in the 600 mg-fed arm and 2 (7.7%) pts in the 750 mg-fasted arm. Table: 1348P

n/Ne: number of events/number of confirmed responders. NE, non-estimable.

Conclusions

Asian pts with ALK+ advanced/metastatic NSCLC treated with ceritinib 450 mg-fed showed numerically higher efficacy and less GI toxicity compared to 750 mg-fasted pts.
