Trial Outcomes & Findings for A Phase 2 Study to Evaluate Axatilimab for Hospitalized Participants With Respiratory Involvement Secondary to COVID-19 (NCT NCT04415073)

NCT ID: NCT04415073

Last Updated: 2022-07-22

Results Overview

Respiratory failure was defined by need for mechanical ventilation, extracorporeal membrane oxygenation, non-invasive ventilation \>6 liters oxygen/minute, or clinical diagnosis of respiratory failure with initiation of none of these measures only when clinical decision-making was driven solely by resource limitation.

Participant Flow

This study was terminated by the Sponsor given enrollment challenges, partly attributable to the constantly changing novel coronavirus disease (COVID-19) treatment landscape. Due to study termination and only 1 participant being enrolled there are concerns regarding participant confidentiality, therefore no data are being reported.

SECONDARY outcome

Timeframe: Baseline, Day 29

Population: This study was terminated by the Sponsor. Due to study termination and only 1 participant being enrolled there are concerns regarding participant confidentiality, therefore no data are being reported.

The change from baseline at Day 29 or hospital discharge or death, if sooner, in the ratio of peripheral hemoglobin oxygen saturation to fraction of inspired oxygen is evaluated.
