Subcutaneous REGEN-COV antibody administration in a community pharmacy

Abstract

BackgroundREGEN-COV is a non-Food and Drug Adminstration approved monoclonal antibody combination of casirivimab/imdevimab. Casirivimab/imdevimab was previously used for the treatment of SARS-CoV-2 infection (COVID-19), under an emergency use authorization, and has demonstrated a reduction in hospitalizations and death. With the ability to administer this monoclonal antibody combination subcutaneously in an outpatient setting, limited community pharmacies became a treatment location for patients. ObjectivesThe objective of this study was to describe an innovative service and evaluate the safety of administering REGEN-COV, a monoclonal antibody combination of casirivimab and imdevimab, in a community pharmacy setting as treatment for COVID-19. Practice DescriptionThis study was conducted in a community pharmacy during traditional business hours. Practice InnovationA novel service of monoclonal antibody administration for the treatment of COVID-19 was implemented in a community pharmacy in response to community needs during the pandemic. Evaluation MethodsA retrospective, observational study was conducted from September 1, 2021 to December 31, 2021. Patients were required to have a positive SARS-CoV-2 test and meet all inclusion and exclusion criteria. Patients were assessed for adverse drug reactions at the time of monoclonal antibody administration and 60-minutes after administration. Patients were contacted by phone to complete a survey to assess patient reported adverse drug reactions post administration, number of patients hospitalized, and number of patients able to return to normal daily activities. ResultsOf the 93 patients included in this study, adverse effects were reported in 4.3% of patients at administration and 9.7% at follow-up. Included patients receiving this service generated $32,688.68 in revenue for the community pharmacy. ConclusionCommunity pharmacists can administer casirivimab/imdevimab safely and effectively in an outpatient setting with low adverse events. This innovative monoclonal antibody administration service should be used as an example for a Call to Action of expansion of pharmacist scope of practice.
