Clinical Trial Summary

This study aims to address the following objectives:

1. To determine the efficacy of IC14, an anti-CD14 chimeric monoclonal antibody, in patients hospitalized with respiratory disease and hypoxemia due to SARS-CoV-2, in terms of improving the time to resolution of disease.

2. To determine the efficacy of IC14 in reducing the severity of respiratory disease in patients hospitalized with respiratory disease due to SARS-CoV-2.

3. To determine the safety of IC14 in patients hospitalized with respiratory disease due to SARS-CoV-2.

Description:

This is a multicenter, randomized, double-blind, placebo-controlled study of IC14, an antibody to CD14, in reducing the severity of respiratory disease in hospitalized Coronavirus Disease 2019 (COVID-19) patients.

Participants will be randomized to IC14 or matching placebo and followed for 60 days after randomization. The study drug will be administered daily on Days 1-4 by intravenous infusion. All participants will receive standard of care antiviral therapy with remdesivir.

Primary	The Time to Clinical Recovery, Defined as the Time From Baseline to the First Day That Subject is in Categories 1, 2, or 3 on the Eight-Point Ordinal Scale Through Day 28.	The Primary Endpoint is time to clinical recovery, defined as the time from baseline to the first day that a subject is in categories 1, 2, or 3 on the Eight-Point Ordinal Scale through Day 28 (range 1 [best] to 8 [worst]). The Eight-Point Ordinal Scale is an assessment of the clinical status on each study day. The Scale is defined as follows: Not hospitalized, no limitations on activities; Not hospitalized, limitation on activities and/or requiring home oxygen; Hospitalized, not requiring supplemental oxygen-no longer requires ongoing medical care; Hospitalized, not requiring supplemental oxygen-requiring ongoing medical care (COVID-19-related or otherwise); Hospitalized, requiring supplemental oxygen; Hospitalized, on non-invasive ventilation or high-flow oxygen devices; Hospitalized, on invasive mechanical ventilation or extracorporeal membrane oxygenation (ECMO); Death	Within the 28 day period following baseline
