简要总结
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.
详细描述
Patients admitted to the hospital with COVID-19 disease with signs of pulmonary involvement will be randomized to receive the anti-IL-6 drug clazakizumab 25mg IV or placebo. Patients will be followed for improvements in clinical symptoms and laboratory parameters which are part of our COVID-19 lab panel described below. Patients will receive standard of care (SOC) supportive treatment and will be followed for 14 days. If a patient from either group progresses to the need for mechanical ventilation and/or ECMO, or develops clinical signs of deteriorating COVID-19 disease, and there are no serious treatment related SAEs, at the discretion of the investigator or treating physician, the patient may receive a single dose of open-label clazakizumab 25mg IV. A minimum of 24 hours should elapse between the first dose of IP and this dose of open-label clazakizumab.
Enrolled patients will receive clazakizumab 25 mg or placebo (0.9% saline) given by IV infusion over 30 minutes. Clazakizumab will be administered in 50 mL of 0.9% saline on Day 1. COVID-19 lab panel and clinical parameters will be monitored to determine if patients are progressing towards need for ventilation and/or ECMO. The parameters below will be monitored and patient status will be assessed by the clinical team.
If patients do develop these criteria, open-label clazakizumab 25 mg IV may be administered as discussed above. A minimum of 24 hours should elapse between the first dose of IP and this dose of open-label clazakizumab. Patients ventilated with or without ECMO will continue to be monitored post-treatment for signs of improvement, (i.e., decreasing FiO2 requirements, chest X-ray (CXR) improvements, C-reactive protein (CRP) reductions, extubation and discharge home) or death.
