Monoclonal Antibody Therapy for COVID-19

Jan 2022 (UPDATE) – Due to the prevalence of the Omicron variant (>80% of current infections), REGEN-COV (casirivimab/imdevimab) and bamlanivimab/etesevimab are no longer recommended for treatment or post-exposure prophylaxis of COVID-19 in Los Angeles County because they are not expected to be effective against the Omicron variant. Sotrovimab remains a recommended treatment but, is in limited supply.

Acute care hospitals that have received allocations of sotrovimab in Los Angeles County can be found here (because supplies are limited, being listed does not confirm current availability).

Evusheld is a long-acting antibody authorized for pre-exposure prophylaxis (prevention) in people with moderate to severe immune compromise due to a medical condition or immunosuppressive medication who may not mount an adequate immune response to COVID-19 vaccine.

Additional therapeutics include Paxlovid and molnupiravir which are oral antiviral medications authorized for the treatment of COVID-19 in people that are at high risk for progression to severe disease. 

These therapeutics are also in limited supply.  More information about COVID-19 therapeutics and access to them in Los Angeles County can be found here:

Monoclonal antibodies are laboratory-made proteins that mimic the immune system’s ability to fight off harmful pathogens such as viruses. REGEN-COV (casirivimab/imdevimab), bamlanivimab/etesevimab, and sotrovimab are monoclonal antibody therapies specifically directed against the spike protein of SARS-CoV-2, designed to block the virus’ attachment and entry into human cells.

Monoclonal antibody therapy may be effective in treating patients with mild or moderate COVID-19, preventing progression and severity of symptoms.  The FDA issued Emergency Use Authorization (EUA) for this treatment for COVID-19 in patients with mild to moderate symptoms and that are high risk for progression to severe COVID-19 and/or hospitalization.  The FDA has also authorized the use of REGEN-COV and bamlanivimab/etesevimab for post-exposure prophylaxis (prevention) in people who have been exposed to the SARS-CoV-2 virus and are at high risk for progression to severe COVID-19. Prophylaxis with REGEN-COV is not a substitute for vaccination against COVID-19. Monoclonal antibodies are not authorized for use in hospitalized patients that are 2 years or older.  Bamlanivimab/etesevimab is authorized for patients of all ages that meet emergency use authorization criteria, including neonates.
