Purpose: We evaluated the cost-effectiveness of high-dose indacaterol acetate (IND)/glycopyrronium bromide (GLY)/mometasone furoate (MF) (150/50/160 μg, once daily) compared with high-dose salmeterol/fluticasone (SAL/FLU; 50/500 µg, twice daily)+tiotropium
(TIO; 5 µg, once daily) (SAL/FLU+TIO) and with high-dose SAL/FLU (50/500 µg, ...
Purpose: We evaluated the cost-effectiveness of high-dose indacaterol acetate (IND)/glycopyrronium bromide (GLY)/mometasone furoate (MF) (150/50/160 μg, once daily) compared with high-dose salmeterol/fluticasone (SAL/FLU; 50/500 µg, twice daily)+tiotropium
(TIO; 5 µg, once daily) (SAL/FLU+TIO) and with high-dose SAL/FLU (50/500 µg, twice
daily) for the treatment of inadequately controlled moderate-to-severe asthma.
Patients and Methods: A Markov model estimated the incremental cost-effectiveness ratio
of treatment with high-dose IND/GLY/MF compared with SAL/FLU+TIO and high-dose
IND/GLY/MF compared with SAL/FLU. The model included three health states (day-to-day
symptoms without exacerbations, day-to-day symptoms with exacerbations, and death) with
a 4-week cycle length. A lifetime time horizon was used. Exacerbation rates and utility
values were derived from ARGON and IRIDIUM clinical trials. Canadian dollars (CAD$,
2020) were applied.
Results: IND/GLY/MF was the less costly and more effective treatment strategy compared
with SAL/FLU+TIO and SAL/FLU in the base-case analyses. IND/GLY/MF had lower costs
(CAD $33,501 versus CAD $50,907) and higher quality-adjusted life-years (QALYs) (18.37
versus 18.06 QALYs) compared with SAL/FLU+TIO. Compared with SAL/FLU, IND/GLY/
MF had lower costs (CAD $33,408 versus CAD $36,577) and higher QALYs (19.33 versus
19.04 QALYs). IND/GLY/MF was the most cost-effective option in all scenarios tested.
Conclusion: IND/GLY/MF was cost-effective at a willingness-to-pay threshold of CAD
$50,000/QALY in patients with uncontrolled, moderate-to-severe asthma versus SAL/FLU
+TIO and SAL/FLU in the base case and all scenarios tested.
