What the study is about
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.
Being studied: Atibuclimab; Placebo
Conditions: Acute Respiratory Distress Syndrome; Adult Respiratory Distress Syndrome; Acute Lung Injury; Acute Lung Injury/Acute Respiratory Distress Syndrome (ARDS)
Eligibility criteria
