Abstract
BACKGROUND: Biologic therapy is a paradigm-shifting management strategy for many patients with asthma and chronic urticaria, but concerns for therapy-associated anaphylaxis may limit access to these therapies for patients unable to travel to medical clinics. OBJECTIVE: To characterize the cost-effectiveness of in-clinic versus at-home biologic therapy with omalizumab and mepolizumab. METHODS: Economic evaluation using microsimulations was performed from societal and health care sector perspectives for patients with asthma or chronic spontaneous urticaria receiving omalizumab or mepolizumab in an allergy clinic, primary care provider (PCP) office, or at home over a 1-year time horizon (12 injections per year in each base case with sensitivity analysis to 24 injections per year). Travel times and distances were applied to a population attending a tertiary care allergy clinic in Northern New England receiving omalizumab or mepolizumab, using a willingness-to-pay value of $10 million per death prevented and in-clinic administration reducing anaphylaxis fatality and hospitalization 10- to100-fold. Deterministic and probabilistic sensitivity analyses were performed. RESULTS: One-way allergy clinic travel distances significantly exceeded local PCP offices (49 miles, 95% CI, 42-56, vs 12 miles, 95% CI, 10-15). In the omalizumab societal analysis, annual PCP and allergy clinic administration cost $1369.14 (mean) ± $51.33 (SD) and $1916.68 ± $40.86, respectively. Small reductions in medication-related fatalities with in-clinic administration were offset by the potential increase in automobile fatalities resulting from traveling to the allergy clinic (14.6 ± 15.0 per million person-years for this strategy). Compared with at-home administration, in-clinic omalizumab administration was not cost-effective, with an incremental cost-effectiveness ratio of $500,648,430 (PCP), and with allergy clinic administration dominated by higher costs and automobile-related fatalities. Routine mepolizumab clinic administration was dominated by at-home administration unless anaphylaxis rates or self-administration teaching costs were high. CONCLUSIONS: For many patients, at-home administration of omalizumab or mepolizumab may be a cost-effective strategy.
