Editorial: Post-Exposure Prophylactic Neutralizing Monoclonal Antibodies to SARS-CoV-2 for Individuals at High Risk for COVID-19.

Regulatory authorities, including the US Food and Drug Administration (FDA), have accelerated diagnostic and therapeutic approvals during the coronavirus disease 2019 (COVID-19) pandemic. Accelerated clinical development and approvals have resulted in vaccine programs for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, some individuals remain at high risk for the progression of COVID-19. In the US, the FDA has given Emergency Use Authorization (EUA) for two neutralizing therapeutic monoclonal antibody 'cocktails,' casirivimab and imdevimab (REGEN-COV), bamlanivimab and etesevimab, and one monotherapy, bamlanivimab, for prophylactic post-exposure therapy in individuals at high risk of progressing to severe COVID-19. Preclinical and clinical studies showed consistent effectiveness of REGEN-COV against current variants of SARS-CoV-2. On 21st November 2020, the FDA approved an initial EUA for REGEN-COV to treat mild to moderate COVID-19 in adults and in children 12 years or older with exposure to SARS-CoV-2 at high risk for progression to severe COVID-19. On 30th July 2021, the FDA updated its EUA for REGEN-COV for emergency use as post-exposure prophylactic to prevent COVID-19 progression in adults and children aged 12 years or older. This Editorial aims to provide an update on accelerated regulatory authorization for post-exposure prophylactic neutralizing monoclonal antibodies to SARS-CoV-2 for individuals at high risk for COVID-19.
