ABSTRACT
BACKGROUND: REGEN-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. OBJECTIVES: The 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 DESCRIPTION: This study was conducted in a community pharmacy during traditional business hours. PRACTICE INNOVATION: A 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 METHODS: A 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. RESULTS: Of 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. CONCLUSION: Community 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.
