Sarilumab for Patients With Moderate COVID-19 Disease: A Randomized Controlled Trial With a Play-The-Winner Design

Detailed Summary

Objectives: To determine whether blockade of IL-6R is beneficial in patients with COVID-19 infection of moderate severity. Research Design: Randomized, controlled trial. Two-arm trial comparing standard care alone to standard care with addition of sarilumab (anti-IL6R). The trial will use a randomized play-the-winner design, in which randomization becomes weighted toward the arm that was more effective in previous subjects in the trial. Methodology Hospitalized patients meeting clinical criteria for moderate disease and testing positive for coronavirus infection. Interventions: sarilumab, 400 mg subcutaneous injection. Standard care is not pre-specified, may vary among patients, and may include agents with anti-viral activity, such as remdesivir or hydroxychloroquine, among others. Up to 120 patients, primary outcome intubation or death within 14 days. All data will be extracted remotely from the electronic health record (EHR). Clinical Implications: The study has potential to establish IL-6R blockade, delivered subcutaneously, as standard of care in reducing progression to critical illness in patients with moderate COVID-19 disease.
