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.

奥马珠单抗治疗食物过敏的成本效益。

背景：奥马利珠单抗是一种新近获得 FDA 批准的抗 IgE 疗法，用于治疗年龄大于 1 岁的单种或多种食物过敏患者：奥马珠单抗是美国 FDA 新近批准的一种抗 IgE 疗法，用于治疗年龄大于 1 岁的单种或多种食物过敏患者的过敏原不可知性：方法：以 15 年为时间跨度，对随机接受奥马珠单抗治疗的模拟食物过敏婴儿马尔可夫队列的健康和经济结果进行评估。采用蒙特卡洛模拟（n=40,000 名受试者）从社会角度评估成本效益，同时纳入家庭层面和个人层面的分析。考虑到治疗效果可能惠及家中所有人员（如护理人员、兄弟姐妹、配偶），而不仅仅是患者，因此纳入了家庭层面的分析，以纳入健康效用变化的广泛视角，代表所有这些人员的变化总和。补充分析探讨了较低的奥马珠单抗成本和居家启动问题。还进行了确定性和概率敏感性分析：在家庭队列分析中，奥马珠单抗超过了成本效益阈值（185,183 美元/QALY）。奥马珠单抗策略（OMA）与非奥马珠单抗策略（NOMA）相比，OMA的成本超过了NOMA（315,020美元 vs 136,609美元），而增量有效性更高（12.668 QALY vs 11.699 QALY）。在个人层面的分析中，OMA 的成本效益为 573,698 美元/QALY。在基础案例评估中，当健康状况效用提高 0.265 时，OMA 具有成本效益（WTP，100,000 美元/QALY）。从个人和家庭单位层面考虑，OMA 的价值成本介于 14,166 美元至 23,791 美元之间。要求在诊所使用 OMA 不具成本效益（ICER，260,239 美元）：结论：在基本情况下，按照目前的定价，奥马珠单抗不具有成本效益，但如果零售价较低，或者使用奥马珠单抗会给家庭和患者带来巨大的健康效用转变，则奥马珠单抗可能具有成本效益。

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.
