Abstract
Background
Omalizumab is an anti-IgE therapy newly approved by the Food and Drug Administration for allergen agnostic treatment of single or multiple food allergies in patients aged 1 year or older.
Objective
Evaluate the cost-effectiveness of omalizumab as a food allergy treatment.
Methods
We evaluated health and economic outcomes in Markov cohorts of simulated food allergic infants randomized to receive omalizumab using a 15-year horizon. Monte Carlo simulation was used (n = 40,000 subjects) to evaluate cost-effectiveness from a societal perspective, incorporating both a family-level and individual-level analysis. We included family-level analysis to incorporate a broad perspective for health utility change, given treatment effects likely benefit all parties at home (eg, caregivers, siblings), not just the patient, representing the sum of changes in all such persons. Supplemental analyses explored lower omalizumab cost and home initiation. We performed deterministic and probabilistic sensitivity analyses.
Results
In the family-level cohort analysis, omalizumab exceeded cost-effectiveness thresholds ($185,183/quality-adjusted life-years [QALY]). In a comparison of the omalizumab strategy (OMA) with the non-omalizumab strategy, the cost of OMA exceeded the non-omalizumab strategy ($315,020 vs $136,609) with greater incremental effectiveness (12.668 vs 11.699 QALY). In the individual-level analysis, the cost-effectiveness of OMA was $573,698/QALY. In base-case assessments, OMA was cost-effective (willingness to pay, $100,000/QALY) at a health state utility (HSU) improvement of 0.265. The value-based cost of OMA ranged from $14,166 to $23,791 when it was considered at the individual and family-unit levels. Requiring OMA administration in the clinic was not cost-effective (incremental cost-effectiveness ratio, $260,239).
Conclusions
In the base case and at current pricing, omalizumab is not cost-effective, but it could be at a lower retail price or when use creates large health utility shifts in the family and patient.
期刊介绍：
JACI: In Practice is an official publication of the American Academy of Allergy, Asthma & Immunology (AAAAI). It is a companion title to The Journal of Allergy and Clinical Immunology, and it aims to provide timely clinical papers, case reports, and management recommendations to clinical allergists and other physicians dealing with allergic and immunologic diseases in their practice. The mission of JACI: In Practice is to offer valid and impactful information that supports evidence-based clinical decisions in the diagnosis and management of asthma, allergies, immunologic conditions, and related diseases.
This journal publishes articles on various conditions treated by allergist-immunologists, including food allergy, respiratory disorders (such as asthma, rhinitis, nasal polyps, sinusitis, cough, ABPA, and hypersensitivity pneumonitis), drug allergy, insect sting allergy, anaphylaxis, dermatologic disorders (such as atopic dermatitis, contact dermatitis, urticaria, angioedema, and HAE), immunodeficiency, autoinflammatory syndromes, eosinophilic disorders, and mast cell disorders.
The focus of the journal is on providing cutting-edge clinical information that practitioners can use in their everyday practice or to acquire new knowledge and skills for the benefit of their patients. However, mechanistic or translational studies without immediate or near future clinical relevance, as well as animal studies, are not within the scope of the journal.
