Regeneron's Arthritis Drug Fails COVID-19 Trial

A clinical trial with thousands of hospitalized coronavirus patients failed to hit the mark for the last time on Thursday. A group of COVID-19 patients requiring mechanical ventilation failed to show measurable improvement when treated in a phase 3 trial with Kevzara from Regeneron (NASDAQ:REGN). In June, Regeneron reported Kevzara's failure to provide a benefit for hospitalized COVID-19 patients severe enough to require oxygen, but not severe enough to require mechanical ventilation.
