Outpatient Use of Monoclonal Antibodies Casirivimab and Imdevimab in Pregnancy for Mild-to-Moderate Coronavirus Disease 2019

Abstract

Objective: The aim of this study was to report the use casirivimab/imdevimab therapy in pregnant women with moderate coronavirus disease 2019 (COVID-19).

Study design: We report 12 cases of unvaccinated pregnant patients with mild-to-moderate COVID-19 treated with casirivimab/imdevimab.

Results: Twelve unvaccinated pregnant patients with mild-to-moderate COVID-19 received casirivimab/imdevimab at the dose of 1200/1200 mg by intravenous infusion over 60 minutes. All women were managed outpatient. None experienced severe adverse drug reaction and none progressed to severe disease.

Conclusion: Casirivimab/imdevimab should be considered for outpatient treatment of unvaccinated pregnant women with mild-to-moderate COVID-19 to decrease the risk of severe disease.

Key points: · Casirivimab/imdevimab is not well studied in pregnant women.. · Casirivimab/imdevimab in pregnant women with mild-to-moderate COVID-19 decreases the risk of severe disease.. · Casirivimab/imdevimab in pregnant women with mild-to-moderate COVID-19 is well tolerated..
