Study Summary

In this study invetigators propose to administer clazakizumab to patients with life-threatening COVID-19 infection manifest by pulmonary failure and a clinical picture consistent with a cytokine storm syndrome. This is a double-blinded randomized multi-center trial designed as a phase II dose-finding three arm trial with seamless adaptive transition to a phase III efficacy trial. For phase II, patients were randomized 1:1:1 ratio to three study arms and received clazakizumab at a dose of 12.5 mg, 25 mg or placebo. Based on interim analysis, the low dose arm was dropped and the phase III portion of the study continued to enroll patients randomized 1:1 to high dose clazakizumab or placebo. Based on interim analysis, the remaining 10 subjects at NYU will be randomly assigned to a 1:1 ratio to two arms that will receive clazakizumab at a dose of 25 mg or placebo. The NYU site will serve as the central data management site for other centers who undertake this protocol. Other sites will enroll patients based on the two arm 1:1 randomization. 60 patients at outside sites are expected to enroll.
