casirivimab/imdevimab (Ronapreve) (n=838) vs. placebo (n=840)
randomized controlled trial some concerns about risk of bias
REGEN-CO 1200mg (casirivimab and imdevimab) IV
Placebo
3 arms: placebo, REGEN-COV 2400mg (1200mg each antibody) and REGEN-COV 1200mg (600mg each antibody). (8,000 mg data were converted to a descriptive analysis)
COVID 19 outpatients
Patients ≥18 years of age and non-hospitalized, with a confirmed local SARS-CoV-2-positive diagnostic test result ≤72 hours and onset of any Covid-19 symptom, as determined by the investigator, ≤7 days before randomization, maintain O2 saturation ≥93% breathing room air, not have prior or current use of putative COVID-19 treatments (e.g. convalescent plasma, systemic corticosteroids or remdesivir) and not have been previously or currently hospitalized for treatment of COVID-19.
Double-blind.
Analysis in modified full analysis set (subjects with positive RT-qPCR test at baseline).The primary and two key secondary endpoints were tested hierarchically. The key secondary clinical endpoints were (1) the proportion of patients with ≥1 Covid-19-related hospitalization or all-cause death from day 4 through day 29 and (2) the time to Covid-19 symptoms resolution (19 of the 23 recorded symptoms).
*Warning! The spread of new Sars-Cov2 variants is constantly evolving, this study was performed in a different viral context than today, its results should be interpreted accordingly.*
