Study Summary

This is a single center, randomized, double-blind, placebo-controlled, exploratory phase II study enrolling 60 patients. We propose the administration of a blinded dose of an investigational product (IP) (clazakizumab or placebo \[0.9% saline\]) in patients with COVID-19 disease and signs of pulmonary involvement who have not yet required mechanical ventilation and/or extracorporeal membrane oxygenation (ECMO). If a patient progresses to mechanical ventilation and/or ECMO or develops clinical signs of deteriorating COVID-19 disease, and there are no treatment related serious adverse events (SAEs), within the initial 14 day period after the first dose of the IP, at the discretion of the investigator or treating physician, open-label clazakizumab 25mg IV x 1 dose may be administered. A minimum of 24 hours should elapse between the first dose of IP and this dose of open-label clazakizumab. The patient will remain blinded as to the identity of the IP administered in the first dose.
