On 16 April 2021, the FDA revoked the emergency use authorization (EUA) for the investigational monoclonal antibody therapy bamlanivimab, when administered alone, to be used for the treatment of mild-to-moderate COVID-19 in adults and certain pediatric patients. [69]
Bebtelovimab is a neutralizing human immunoglobulin G1 (IgG1) monoclonal antibody, isolated from a patient who has recovered from the Coronavirus disease 2019 (COVID-19), directed against the spike (S) protein of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), that can potentially be used for immunization against COVID-19.
Bamlanivimab is a monoclonal antibody developed by AbCellera Biologics and Eli Lilly as a treatment for COVID-19. [8] The medication was granted an emergency use authorization (EUA) by the US Food and Drug Administration (FDA) in November 2020, [9] [10] [11] and the EUA was revoked in April 2021.
This list of over 500 monoclonal antibodies includes approved and investigational drugs as well as drugs that have been withdrawn from market; consequently, the column Use does not necessarily indicate clinical usage. See the list of FDA-approved therapeutic monoclonal antibodies in the monoclonal antibody therapy page.
In February 2021, the FDA issued an emergency use authorization (EUA) for bamlanivimab and etesevimab administered together for the treatment of mild to moderate COVID-19 in people twelve years of age or older weighing at least 40 kilograms (88 lb) who test positive for SARS‑CoV‑2 and who are at high risk for progressing to severe COVID-19.
A benefit of casirivimab and imdevimab treatment has not been shown in people hospitalized due to COVID‑19. [9] Monoclonal antibodies, such as casirivimab and imdevimab, may be associated with worse clinical outcomes when administered to hospitalized people with COVID‑19 requiring high flow oxygen or mechanical ventilation. [9]
A general representation of the method used to produce monoclonal antibodies [1] [2] A monoclonal antibody (mAb, more rarely called moAb) is an antibody produced from a cell lineage made by cloning a unique white blood cell. All subsequent antibodies derived this way trace back to a unique parent cell.
In 2020, researchers at Vanderbilt University Medical Center discovered particularly potent monoclonal antibodies, isolated from COVID-19 patients infected with a SARS-CoV-2 circulating at that time. Initially designated COV2-2196 and COV2-2130, antibody engineering was used to transfer their SARS-CoV-2 binding specificity to IgG scaffolds that ...
