ABSTRACT
Background
Cost-effectiveness studies evaluate health technologies and help choose treatments. The current study compared dupilumab to omalizumab, mepolizumab, and benralizumab in Colombian adults with severe uncontrolled type 2 asthma.
Methods
Over a 5-year period, a Markov model was utilized to assess the costs of biological treatments and management of exacerbations, comparing various doses of exacerbations, comparing various doses of dupilumab, omalizumab, mepolizumab, and benralizumab as add-on treatments. It included a 5% annual discount rate per local HTA, and set willingness-to-pay at three times GDP per capita per quality-adjusted life year (QALY) in Colombia.
Results
Dupilumab (200 mg) exhibited greater QALYs and reduced overall costs compared to mepolizumab (100 mg), benralizumab (30 mg), and omalizumab (450 mg and 600 mg), with the incremental cost-effectiveness ratio (ICER) per QALYgained being -$5.429, -$6.269, -$196.567 and -$991.007, respectively. Dupilumab had greater QALYs and costs versus omalizumab 300 mg (ICERof $200.653 per QALY, above the willingness-to-pay threshold of 3 × GDP per capita). Sensitivity analyses were consistent with base case results.
Conclusions
Dupilumab 200 mg was strongly dominant versus omalizumab 450 mg and 600 mg, mepolizumab 100 mg, and benralizumab 30 mg; however, cost-effectiveness was not demonstrated versus omalizumab 300 mg. These results could assist healthcare professionals in choosing an appropriate biologic for treating severe type 2 asthma.
