Among the findings, the DSMB reported a 28-day death rate of 14.3% (2/14) in the EB05 arm versus 36.8% (7/19) in the placebo arm in critically severe patients on ECMO therapy (extracorporeal membrane oxygenation).
Survival Analysis using Cox's Proportional Hazard Model showed that the patients treated with EB05 plus standard of care had a 68.5% reduction in the risk of dying when compared to placebo plus standard of care at 28 days (HR: 3.17 placebo vs. EB05; 95% CI: 0.66-15.35; p=0.15).
The currently available data indicates that greater than 90% of patients received dexamethasone (or other steroids), more than 45% received both tocilizumab and a steroid.
