FinalCenter for Drug Evaluation and Research12/21/2023

Description

The Food and Drug Administration (FDA or Agency) is announcing the availability of a final guidance for industry entitled “Development of Monoclonal Antibody Products Targeting SARS-CoV-2 for Emergency Use Authorization.”  This guidance provides recommendations to sponsors on the development of monoclonal antibody products targeting SARS-CoV-2 intended for the prevention or treatment of COVID-19, including addressing the impact of emerging variants.  The recommendations focus on the data and information that may be used to support a request for emergency use authorization (EUA) under the Federal Food, Drug, and Cosmetic Act (FD&C Act).  This guidance supersedes the guidance entitled “Development of Monoclonal Antibody Products Targeting SARS-CoV-2, Including Addressing the Impact of Emerging Variants, During the COVID-19 Public Health Emergency” issued on February 22, 2021.
