A Study to Evaluate the Efficacy and Safety of Itolizumab in Subjects Hospitalized With COVID-19

This study will randomize up to 800 subjects in a 1:1 ratio; itolizumab vs. placebo. Subjects will receive either itolizumab or placebo administered intravenously on Day 1 and Day 8 with follow-up to Day 90. Two interim analyses of futility are planned. The first will take place when approximately 20% of the subjects have been evaluated for the primary endpoint, and the second will take place when approximately 50% of the subjects have been evaluated for the primary endpoint.
