ABSTRACT
OBJECTIVE:
Non-small cell lung cancer (NSCLC) accounts for 80-90% of all lung cancer cases and is usually associated with a poor prognosis. However, targeted therapy with first and second generation tyrosine kinase inhibitors (TKIs) has so far improved progression-free survival of epidermal growth factor receptor (EGFR) mutant NSCLC patients. Osimertinib, a third generation EGFR TKI has recently shown improved overall survival of 6.8 months in previously untreated EGFR mutant NSCLC patients. We assessed the cost-effectiveness of osimertinib versus standard EGFR TKIs (gefitinib or erlotinib) as first-line treatment for advanced or metastatic EGFR mutant NSCLC patients in Singapore.METHODS:
A partitioned survival model with three health states (progression-free, progressive disease, and death) was developed from the Singapore healthcare payer perspective. Survival curves based on the overall trial population from the FLAURA trial were extrapolated beyond trial period over a 10-year time horizon to estimate the underlying progression-free survival and overall survival parametric distributions. Health state utilities were derived from the literature and direct costs were sourced from public healthcare institutions in Singapore. Deterministic and probabilistic sensitivity analyses were conducted to explore the impact of uncertainties and assumptions on cost-effectiveness results.RESULTS:
Compared with first or second generation TKI, osimertinib had a base-case incremental cost-effectiveness ratio (ICER) of SG$418,839 (US$304,277) per quality-adjusted life year gained. One-way sensitivity analysis showed the ICER was most sensitive to time horizon and variations in progression-free utility values. Scenario analyses showed that a 50% reduction in the cost of osimertinib was still associated with a high ICER that was unlikely to be deemed cost effective.CONCLUSIONS:
Osimertinib is not cost effective as a first-line treatment compared to standard EGFR TKIs in advanced EGFR mutant NSCLC patients in Singapore. The findings from our evaluation, alongside other considerations including the lack of survival benefit in the Asian subgroup of the FLAURA trial, will be useful to inform policy makers on funding decisions for NSCLC treatments in Singapore.Palavras-chave
