Clinical Trial Summary

In this study, the investigators propose to administer clazakizumab to patients with life-threatening Coronavirus Disease 2019 (COVID-19) infection manifest by pulmonary failure and a clinical picture consistent with a cytokine storm syndrome. This is a single-center randomized, double-blind, placebo-controlled trial in which 30 patients will be enrolled and randomly assigned in a 1:1 ratio to two study arms and receive clazakizumab at a dose of 25 mg or placebo.


Clinical Trial Description

The limited understanding of the clinical behavior of patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (the viral organism responsible for COVID-19 disease) is evolving on a daily basis. Reports from China indicate that a subset of patients with the worst clinical outcomes may manifest cytokine storm syndrome. Hypotheses that excess cytokines may trigger a secondary hemophagocytic lymphohistiocytosis (sHLH) have been proposed. Indeed, cytokine profiles consistent with this picture were observed in Chinese patients with severe pulmonary involvement. Specifically, elevated ferritin and interleukin-6 (IL-6) were associated with fatalities among the infected patients. A role for targeted anti-inflammatory and anti-cytokine therapies in the treatment of pulmonary hyperinflammation has been proposed. Clazakizumab is a genetically engineered humanized immunoglobulin-1 (IgG1) monoclonal antibody (mAb) that binds with high affinity to human IL-6. This investigational agent is currently being studied as a treatment for chronic active antibody mediated rejection of renal allografts. In this study investigators propose to administer clazakizumab to patients with life-threatening pulmonary failure secondary to COVID-19 disease. ;
