About this study

Official title: A Phase II Trial to Evaluate the Safety and Tolerability of Clazakizumab® (Anti-IL-6 Monoclonal) Compared to Placebo for the Treatment of COVID-19 Infection

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.

Read the detailed description

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.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Clazakizumab in people with COVID-19, run by Cedars-Sinai Medical Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Feb 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 2 Dec 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety of Clazakizumab for the Treatment of Patients With COVID-19 Disease (time frame: 14 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Feb 2024.
