Abstract

Limited post-crizotinib treatment options for ALK-positive non-small cell lung cancer (NSCLC) might lead to poor survival and high economic burden.To evaluate real-world treatment patterns, overall survival (OS), and costs following crizotinib discontinuation.This study used chart review and claims data. First, 27 participating US oncologists reviewed medical records of ALK-positive NSCLC patients who discontinued crizotinib monotherapy and reported patient demographic and clinical information, including post-crizotinib treatment and mortality. OS was estimated using Kaplan-Meier analyses. Second, three large administrative US claims databases were pooled. NSCLC patients were selected if they discontinued crizotinib monotherapy. Post-crizotinib costs were analyzed separately for patients who did or did not discontinue antineoplastic treatment after crizotinib monotherapy. All data were collected prior to ceritinib approval for this patient population.A total of 119 ALK-positive NSCLC patients discontinued crizotinib monotherapy. Upon discontinuation, 42% had no additional antineoplastic treatment and 13% received radiation therapy only. The median OS post-crizotinib was 61 days; patients with brain metastases had shorter OS than those who did not (44 vs. 69 days, P?=?0.018), and patients without further antineoplastic treatment had shorter OS than those who did (17 vs. 180 days, P?
