O16.03 - Cost-utility analysis of first-line treatment with erlotinib versus chemotherapy in EGFR-mutant advanced non-small-cell lung cancer (NSCLC): economic analysis of EURTAC trial (ID 1100)
10:30 - 12:00 | Author(s): E. Wright
The impact of tyrosine kinase inhibitors (TKIs) in EGFR-mutant advanced NSCLC is poorly documented. Two studies (Jacob et al, ISPOR2010, Brown et al, Health Technol Assess, 2010) are based on modelisation and indirect comparisons. The present study reports a cost-utility analysis of a phase III randomized trial (EURTAC).
A three state Markov model (first line PFS, second line PD and death) was built. Clinical data and resource assessment (drugs, drug administration, adverse events, second-line treatment) were collected from the trial. Utility values were derived from Nafees et al, as previously published (Vergnenegre et al. JTO 2011). Incremental cost-utility ratios (ICUR) were calculated for the first-line treatment and the overall strategy until death from the perspective of different countries (2013 actualized euros). Sensitivity analyses researched the main cost drivers.
The quality-adjusted life-years gained was 0.124 with erlotinib, which showed an improvement in the quality of life for these patients. Despite the extra treatment costs of second-line erlotinib in the chemotherapy arm, there was a cost benefit for erlotinib first, resulting in fewer patients receiving second-line pemetrexed along with other therapy. Cost gain in favor of first-line erlotinib was 8,918 Euros. The main results are depicted in Table1.
Sensitivity analyses will be presented at the meeting.
First-line erlotinib First-line chemotherapy Average cost of first-line (euros 2013) Drugs 21,679 1030 Administration 329 4,455 Adverse events 546 2,686 Cost of post-first progression care 40,467 67,281 ICUR (erlotinib versus chemotherapy) ICUR France negative ICUR Spain negative ICUR Italy negative
ICUR favored first-line erlotinib in EGFR-mutant patients with advanced NSCLC, which is the widely accepted treatment compared to chemotherapy. The cost-utility of the overall strategy remained beneficial in three different European countries. On behalf GFCP,GEPC and AIOT groups
