Efficacy and safety of casirivimab-imdevimab combination on COVID-19 patients: A systematic review and meta-analysis randomized controlled trial

Abstract

Background: The advantages and disadvantages of casirivimab-imdevimab for coronavirus disease 2019 are not well understood. We conducted a systematic review and meta-analysis of relevant literature to determine the therapeutic effectiveness and potential side effects of casirivimab-imdevimab in COVID-19 patients. Methods: Databases were searched from the time of their commencement until February 28th, 2023. The primary results evaluated were the death rate at 28 days, progression of current clinical symptoms within 28 days, viral load, discharge from hospital, and any adverse events. Also, we contrasted the effects of the casirivimab-imdevimab treatment with placebo or standard of care. The protocol registration for this systematic review and meta-analysis was recorded in the PROSPERO database (CRD42023412835). Results: A total of eight studies were included, comprising 19,819 patients, and conducted a qualitative assessment of their risk of bias using the Cochrane risk of bias tool. Casirivimab-imdevimab effectively reduced the mortality rate (OR = 0.62; 95 % CI of 0.40–0.98; p = 0.04; I2 = 30 %) and reduced the progression of clinical symptoms (OR = 0.86; 95 % CI of 0.79–0.93; p = 0.0003; I2 = 57 %). Casirivimab-imdevimab also improved viral load clearance and hospital discharge. Additionally, the trials' findings demonstrated a slight decrease in the likelihood of adverse events occurring with the use of casirivimab-imdevimab. Conclusion: Our research suggests that casirivimab-imdevimab may be a valuable, safe, and effective anti-SARS-CoV-2 regimen.
