Clinical Trial
Study Details
One single intravenous infusion at 8 mg/kg (up to a maximum of 800 mg) for patients ≥ 30 kg and 12 mg/kg for patients \< 30 kg
One single intravenous infusion
The purpose of this study is to determine whether a single infusion of tocilizumab is effective in reducing the time to successful weaning from both supplemental oxygen and any respiratory support, in pediatric and adult patients with sickle cell disease (SCD) during acute chest syndrome (ACS).
Study Overview
SCD is a severe hemoglobinopathy, considered the first monogenic disease in the world. ACS, one of the most frequent and serious complications of SCD, is the first cause of hospitalization and mortality of SCD patients in intensive care unit. However, its pathophysiology has long been poorly understood and therapeutic options are limited.
A major increase has been recently reported in the level of interleukin-6 (IL-6), unlike other main pro-inflammatory cytokines, in the sputum (or bronchoalveolar fluid) from SCD children during ACS, positively correlated with the severity of ACS. Also, the observations of a very rapidly favorable outcome after administration of tocilizumab (anti-human IL-6 receptor monoclonal antibody) in SCD patients hospitalized for ACS with or without SARS-CoV-2 infection, suggest that tocilizumab may be a key therapy for ACS.
