Aims: To assess the cost-effectiveness of tezepelumab as add-on maintenance therapy compared with standard of care (SoC) for the treatment of patients with severe asthma in Canada.
Material And Methods: A cost utility analysis was conducted using a Markov cohort model with five health states ("controlled asthma", "uncontrolled asthma", "previously controlled asthma with exacerbation", "previously uncontrolled asthma with exacerbation", and "death"). Tezepelumab plus SoC was compared to SoC (high-dose inhaled corticosteroids plus long-acting beta agonist) using efficacy estimates derived from the NAVIGATOR (NCT03347279) and SOURCE (NCT03406078) trials. The model included the costs of therapy, administration, resource use for disease management, and adverse events. Utility estimates were calculated using a mixed-effects regression analysis of the NAVIGATOR and SOURCE trials. A Canadian public payer perspective was used with a 50-year time horizon, a 1.5% annual discount rate, and the base case analysis was conducted probabilistically. A key scenario analysis assessed the cost-effectiveness of tezepelumab compared with currently reimbursed biologics informed by an indirect treatment comparison.
Results: The base case analysis suggested that tezepelumab plus SoC was associated with a quality-adjusted life-year (QALY) gain of 1.077 compared with SoC alone at an incremental cost of $207,101 (2022 Canadian dollars), resulting in an incremental cost-utility ratio of $192,357/QALY. The key scenario analysis demonstrated that tezepelumab was dominant against all currently reimbursed biologics, with higher incremental QALYs (ranging from 0.062 to 0.407) and lower incremental costs (ranging from -$6,878 to -$1,974). Additionally, when compared against currently reimbursed biologics in Canada, tezepelumab had the highest probability of being cost-effective across all willingness-to-pay (WTP) thresholds.
Conclusion: Tezepelumab provided additional life years and QALYs at additional cost compared with SoC in Canada. In addition, tezepelumab dominated (i.e. more effective, less costly) the other currently reimbursed biologics.
