Retrospective 4,396 casirivimab/imdevimab patients in the USA, showing lower combined mortality/hospitalization (CDM database) and lower hospitalization (PMTX+ database) with treatment.
Efficacy is variant dependent. In Vitro research suggests a lack of efficacy for omicron [Liu, Sheward, Tatham, VanBlargan].
risk of death/hospitalization, 61.0% lower, HR 0.39, p < 0.001, treatment 23 of 1,116 (2.1%), control 27 of 5,291 (0.5%), Optum CDM, Cox proportional hazards.
risk of hospitalization, 61.0% lower, HR 0.39, p < 0.001, treatment 59 of 3,280 (1.8%), control 75 of 16,284 (0.5%), IQVIA PMTX+, Cox proportional hazards.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates

Abstract Background: In a phase III clinical trial, casirivimab and imdevimab (CAS+IMD) reduced the composite endpoint of COVID-19-related hospitalizations or all-cause mortality in outpatients at risk of severe disease. This study assessed real-world effectiveness of CAS+IMD. Methods: Data from Optum® Clinformatics® Data Mart (CDM) and IQVIA Pharmetrics Plus (PMTX+) were used to identify patients diagnosed with COVID-19 in ambulatory settings between December 2020 and March 2021 (PMTX+) and June 2021 (CDM), and either treated with CAS+IMD or untreated but treatment-eligible under Emergency Use Authorization. CAS+IMD-treated patients were matched to untreated patients and followed up to 30 days for the outcome of all-cause mortality or COVID-19-related hospitalizations (CDM) and COVID-19-related hospitalizations (PMTX+). Kaplan-Meier estimators were used to calculate outcome risks; Cox proportional-hazard models estimated adjusted hazard ratios (aHR) with 95% confidence intervals (CI). Results: For CDM, 1116 CAS+IMD-treated patients were matched to 5294 untreated patients; for PMTX+, 3280 CAS+IMD-treated patients were matched to 16,284 untreated patients. The 30-day outcome risk was 2.1% and 5.3% in treated and untreated cohorts, respectively (CDM), and the 30-day risk of COVID-19-related hospitalization was 1.9% and 4.8%, respectively (PMTX+); translating to a 61% lower adjusted outcome risk (CDM aHR 0.39 (95% CI 0.26–0.60; PMTX+ aHR 0.39 (95% CI 0.30–0.51). The benefit of treatment was maintained across multiple subgroups of highrisk patients; earlier intervention was associated with improved outcomes. 2 medRxiv preprint doi: https://doi.org/10.1101/2022.02.28.22270796; this version posted February 28, 2022.
