Dupilumab-Treated Patients with Asthma in the Real World: The RAPID Global Registry.

ABSTRACT

BACKGROUND: Dupilumab, a fully human monoclonal antibody, blocks the shared receptor component for interleukin-4 and interleukin-13, key and central drivers of type 2 inflammation. In clinical studies, dupilumab reduced the risk of severe asthma exacerbations, and improved forced expiratory volume in 1 s and quality of life in patients with uncontrolled moderate-to-severe asthma. OBJECTIVES: The objectives of RAPID (NCT04287621) are to characterize patients with asthma initiating dupilumab in routine clinical practice and to collect information on long-term effectiveness and safety in these patients. METHODS: RAPID is a global, prospective, observational registry that will enroll approximately 1000 patients (aged ≥ 12 years) with asthma from 150 sites globally. Dupilumab treatment will be initiated in routine clinical practice according to country-specific prescribing information, per physician discretion as part of routine care. Patients will be followed prospectively for up to 3 years, with postbaseline assessments at months 1 and 3, and every 3 months thereafter. PLANNED OUTCOMES: Baseline data collected will include patient demographics, disease characteristics, and medication history. Patient adherence and persistence will be recorded alongside health-care resource utilization, and effectiveness of dupilumab will be assessed (clinician assessment) as per standard of care. Quality of life, asthma control, type 2 inflammatory comorbidities, work productivity, and physical activity limitation will be assessed. Incidence and severity of adverse events will be recorded. CONCLUSION: RAPID is the first global registry to characterize patients beginning dupilumab treatment for asthma in clinical practice and will expand on prior clinical studies by providing real-world data.
