Research progress of therapeutic antibodies against COVID-19

ABSTRACT

Antibody-based biological products have gradually become a new strategy for the treatment of infectious diseases. In the past few years, especially after the outbreak of the COVID-19 in 2019, researches on therapeutic SARS-CoV-2 antibodies have greatly developed. Researchers around the world have developed a series of antibody treatment programs with extremely high efficiency to fight against COVID-19. From the early days of the pandemic, therapeutic antibodies were only used for emergency treatment of clinically severe patients, now they can be used for both pre-exposure prophylaxis and post-infection treatment. We summarize the research progress of therapeutic antibodies for SARS-CoV-2, including convalescent plasma, animal antiserum, marketed mAbs, non-targeted therapeutic mAbs, and bispecific antibodies, etc. The limitations and future application prospects of the SARS-CoV-2 therapeutic mAbs are also discussed.
