Abstract 5405

Background

Novel therapies are replacing established treatment options for patients with advanced non-small cell lung cancer (aNSCLC), which poses a challenge to healthcare budgets. The impact of Treatment Evolution in NSCLC (iTEN) model is a validated discrete event patient simulation designed to estimate the impact of treatment sequencing in aNSCLC. The impact of five novel therapies (osimertinib, alectinib, brigatinib, dabrafenib and trametinib, and pembrolizumab combination therapy) changing aNSCLC management in Canada was modelled.

Methods

Current Canadian treatment practices were established via a modified Delphi process with Canadian clinical experts. The table presents potential treatment sequences for biomarker positive aNSCLC with the novel therapies. Clinical efficacy of treatments was estimated from Kaplan–Meier progression-free and overall survival data, as previously described (Moldaver et al. 2018). Modelled costs (2018 CDN $) included drug acquisition and administration costs and the costs of ongoing monitoring, imaging, physician visits, end-of-life, best supportive care, and adverse event management. A treatment rate of 100% in the first-line and 60% thereafter was modelled.Table:

Results

Introduction of these five therapies was estimated to increase the average 1- and 3-year survival of Canadian aNSCLC patients from 69% and 14% to 73% and 21%, respectively. Estimated average lifetime cost per treated patient rose from $159,764 to $269,056. ALK positive patients were estimated to have the largest increase in 3-year survival, from 35% to 64%, and cost of treatment, from $315,333 to $747,859.

Conclusions

New therapies for aNSCLC are likely to increase the survival and average cost of treatment in Canada.
