|In the register|
Pulmonary ordinal outcome [ Time Frame: Day 5 ]
Oxygen requirements measured by 7 categories (1 = least severe, 7 = most severe). The participant's highest (i.e. most severe) observed score is used ;
Pulmonary+ ordinal outcome [ Time Frame: Day 5 ]
Extrapulmonary complications and respiratory dysfunction measured by 7 categories (1= least severe, 7 = most severe). The participant's highest (i.e. most severe) observed score is used.
Time from randomization to sustained recovery [Time Frame: Up to Day 90 ]
Sustained recovery defined as being discharged from the index hospitalization, followed by being alive and home for 14 consecutive days prior to Day 90.
|In the report|
Time to a sustained recovery, which was defined as hospital discharge to home and remaining at home for at least 14 days. Two ordinal outcomes that are measured at day 5 both classified according to seven-level ordinal scales, are termed pulmonary
Yes. In English
|Risk of bias
The overall risk of bias reported in the table corresponds to the highest risk of bias for the outcomes assessed for the systematic review
In addition to the published article, the trial registry, study protocol, statistical analysis plan and supplementary materials were used in data extraction and assessment of risk of bias. There were no substantive differences between the published article and the trial registry, study protocol and statistical analysis plan. The trial did not achieve its pre-stated sample size as it was terminated for futility on the recommendation of the data and safety monitoring board.
Quote: "In order to respond to pandemic dynamics, this platform protocol incorporates an early futility and safety evaluation after the enrollment of 300 patients (stage 1). Stage 1 is then followed by enrollment to the full sample size (stage 2) for agents that pass the initial futility and safety assessment." "The analysis data set was locked on November 6, 2020, and includes deaths, serious adverse events, organfailure events, and hospital discharges that occurred up to October 26."
Chance imbalances in illness severity at baseline were detected and reported by the authors, but adjusted analyses did not suggest benefit for LY-CoV555 in this patient population.
This trial was updated on July 29th, 2021 with data from a preprint article reporting final results.
