The use of monoclonal antibodies has expanded beyond the realm of autoimmune disease and cancer therapeutics to communicable diseases. Their antiviral activities were evaluated in some diseases such as SARS MERS (Middle East Respiratory Syndrome) and Ebola. In recent times, antispike SARS-CoV-2 monoclonal antibody cocktails (casirivimab with imdevimab and bamlanivimab with etesevimab) and single agent sotrovimab have received emergency use authorization for treatment of nonhospitalized COVID-19 patients with mild-to-moderate disease at high risk of disease progression. This review summarizes their mechanism of action, salient pharmacokinetic profile, safety and clinical trial (ongoing and completed) data. Despite evidence to support its use for the indication, the high cost of these biologics may make it unaffordable for many patients, but further clinical studies on their cost-benefit profile shall provide useful information to the scientific community and patients.
