- Type
- SECONDARY
- Title
- Number of Participants That Experienced Death or Death Equivalent
- Description
The number of participants who died or met the criterion for a death equivalent from the date of their baseline visit to the end of the Week 24visit window (generally 175 days after baseline). The death equivalent criterion is use of permanent assisted ventilation (PAV) for more than 22 hours per day for more than 7 days in a row.
- Time frame
- Baseline to 24 Weeks
- Population
Outcome measure data was analyzed using the Full Analysis Set, which included shared placebo from other regimens, as pre-specified in the Regimen Statistical Analysis Plan. Regimen A (NCT04436497), Regimen B (NCT04436510) and Regimen C (NCT04414345) contributed placebo participants into the shared placebo cohort used for analysis.
