Study Endpoints
Primary Endpoints
Time to First Occurrence of Composite Endpoint of Cardiovascular (CV) Death or Heart Failure (HF) Hospitalization
Up to approximately 33 months (through primary analysis database cutoff date of 18-June-2019)

Time to First Occurrence of Composite Endpoint of CV Death or HF Hospitalization was analyzed using a one-sided stratified log-rank test. Randomized participants without any HF hospitalization or CV death event at the time of analysis were censored at their last available information, the date of their non-CV death, or the primary analysis database cutoff date of 18-June-2019, whichever occurred first. A clinical events committee (CEC) reviewed and adjudicated the endpoint events. A time-to-event methodology was used to evaluate the results; the incidence rate of participants with an event (number of participants with an event per 100 participant-years at risk) is provided.

Base Period: Change from baseline to Week 16 in N-terminal pro-brain natriuretic peptide (NT-proBNP)
Baseline and Week 16 of Base Period

The change from baseline to Week 16 of the Base Period in log-transformed NT-proBNP will be reported.

Extension Period: Percentage of participants with one or more adverse events (AEs)
Includes data collected up to a maximum of approximately 8 years

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The percentage of participants with one or more AEs in the Extension Period will be reported.

Extension Period: Percentage of participants who discontinued study drug due to an AE
Includes data collected up to a maximum of approximately 8 years

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The percentage of participants who discontinue study drug in the Extension Period due to an AE will be reported.

Secondary Endpoints
Time to the First Occurrence of CV Death
Up to approximately 33 months (through primary analysis database cutoff date of 18-June-2019)
Time to the First Occurrence of HF Hospitalization
Up to approximately 33 months (through primary analysis database cutoff date of 18-June-2019)
Time to Total HF Hospitalizations (Including First and Recurrent Events)
Up to approximately 33 months (through primary analysis database cutoff date of 18-June-2019)
