What You Need to Know Before You Apply

What is the purpose of this trial?

Hospitalized patients with ARDS will be randomized to intravenous treatment with a monoclonal antibody against CD14, called IC14, or placebo. They will be followed for 28 days. The primary outcome is the day 4 oxygenation index assessed as a continuous measure.

Do I need to stop my current medications for the trial?

The trial requires that you have not been treated with certain immunosuppressant or immunomodulatory drugs within 30 days or five half-lives, whichever is longer. Other medications are not specifically mentioned, so it's best to discuss your current medications with the trial team.

How is the drug Atibuclimab unique in treating ARDS?

Atibuclimab is unique because it targets CD14, a molecule involved in the body's immune response, which is different from other treatments that often target tumor necrosis factor (TNF) or programmed death ligand-1 (PD-L1). This novel approach may offer a different mechanism to manage the inflammation associated with ARDS. ^{1 2 3 4 5}

What Are the Treatments Tested in This Trial?

Interventions

• Atibuclimab

Trial Overview The study tests IC14, an antibody treatment against CD14 in the blood, versus a placebo. Patients are randomly assigned to one of these treatments and monitored for oxygen levels over 28 days.

How Is the Trial Designed?

Group I: IC14 (atibuclimab) Experimental Treatment 1 Intervention

IC14 (atibuclimab) is a recombinant monoclonal antibody against human CD14

Group II: Identical-appearing placebo Placebo Group 1 Intervention

Sterile normal saline

Atibuclimab is already approved in United States for the following indications:

Approved in United States as Atibuclimab for:

• Acute Decompensated Heart Failure (clinical trial phase, not yet approved)
