Trial Outcomes & Findings for Tocilizumab for Prevention of Respiratory Failure in Patients With Severe COVID-19 Infection (NCT NCT04377659)

NCT ID: NCT04377659

Last Updated: 2025-05-28

Results Overview

The primary endpoint for this cohort is progression of respiratory failure (binary yes/no while hospitalized). Progression of respiratory failure will be defined as a sustained increase in oxygen requirement (FiO2) or need for intubation/mechanical ventilation.

Measure
Intubation/Mechanical Ventilation
Progression of respiratory failure in cohort #1 will be defined as a sustained increase in oxygen requirement or need for intubation/mechanical ventilation Tocilizumab: Participants will receive Tocilizumab 8 mg/kg i.v. at enrollment. Dose will be capped at 800 mg per infusion. If there is no improvement or toxicity, a second dose can be given 24 hrs to 5 days later.
Respiratory Support
In cohort #2 progression of respiratory failure will be defined as a need for increasing respiratory support (e.g. FiO2 or PEEP) Tocilizumab: Participants will receive Tocilizumab 8 mg/kg i.v. at enrollment. Dose will be capped at 800 mg per infusion. If there is no improvement or toxicity, a second dose can be given 24 hrs to 5 days later.
