Challenges to ongoing efforts to provide effective aid for hospitalized patients with COVID-19 continued April 8, with two new trial failures reported. A phase III trial testing the Olumiant (baricitinib) vs. placebo, both on top of standard of care, missed its primary endpoint of progression to non-invasive ventilation, invasive mechanical ventilation or death, said drugmakers Eli Lilly and Co. and Incyte Corp. A phase II trial testing Beigene Ltd.'s Brukinsa (zanubrutinib) vs. placebo in patients hospitalized with respiratory symptoms of COVID-19 also fell short, missing its co-primary efficacy endpoints of respiratory failure-free survival or reduction in days on oxygen.
