Implementation and Patient Outcomes of a Pediatric COVID-19 Monoclonal Antibody Program

Abstract

Abstract Background The severity and reach of the COVID-19 pandemic drove the development of various therapeutic approaches to combat SARS-CoV-2, including several neutralizing monoclonal antibody (mAb) therapies. A January 2021 pediatric consensus statement opposed routine use and recommended individualized risk assessments when considering COVID-19 mAb therapies in children and adolescents due to limited data. This report describes the implementation of a mAb referral process and the clinical outcomes of patients who received a mAb infusion in a pediatric hospital. Methods We developed a tiered allocation system based on underlying medical conditions and incorporated it into a standardized COVID-19 mAb referral and approval process. Demographics and clinical data were collected on all patients who received mAb therapy for treatment or post-exposure prophylaxis. Data recorded included sociodemographics, qualifying underlying medical conditions, clinical manifestations of infection, and overall course of treatment and disease. Results A total of 182 patients ≤21 years old received a COVID-19 mAb infusion between November 27, 2020 and January 26, 2022. Patient age ranged from 10 months to 21 years, with a median age of 15 years. In total, 7 patients (4%) had suspected adverse reactions during the infusion, and 15 (8%) patients required a COVID-19-related visit within 30 days of the mAb infusion. Conclusions A tiered allocation process may provide the framework for the stratification and efficient distribution of mAb therapies. Future research must focus on the efficacy of these therapies in the pediatric population, standardized therapeutic prioritization, and the optimal timeframe for mAb delivery to prevent progression to severe disease.
