KCCQ is a 23-item, self-administered instrument that quantifies physical function, symptoms (frequency, severity and recent change), social function, self-efficacy and knowledge, and quality of life. The KCCQ-TSS incorporates the symptom frequency (4 items) and symptom burden (3 items) domains into a single summary score. The score is transformed to a range of 0-100, in which a higher score reflects better health status. Baseline value is the last value on or prior to the randomization visit. Deaths are treated as the worst outcome and ordering among deaths is based on last value while alive. In rank ANCOVA and HL estimation, multiple imputation was performed on missing values for participants who were alive at the visit at week 16 but did not have KCCQ-TSS values.

Change From Baseline in 6-minute Walk Distance (6MWD) at Week 16 (Larger Distances Represent Better Functional Capacity).

Change from baseline in 6-minute walk distance (6MWD) (exercise capacity) at week 16 was defined as the distance walked in 6 minutes at week 16 minus the baseline value. Baseline value is the last value on or prior to the randomization visit. Deaths are treated as the worst outcome and ordering among deaths is based on last value while alive. In rank ANCOVA and HL estimation, multiple imputation was performed on missing values for participants who were alive at the visit at week 16 but did not have 6MWD values.

Time frame: At baseline and at week 16 or death prior to week 16

Change From Baseline at the End of the Study in the Total Time Spent in Light to Vigorous Physical Activity, as Assessed Using a Wearable Activity Monitor (Accelerometer).

Change from baseline at the end of the study in total time spent in light to vigorous physical activity (LVPA), as assessed using a wearable activity monitor, was defined as the total time \[per day\] spent in LVPA at the end of the study minus the baseline value. Baseline is the 7 day period starting on the day of enrolment and ending before randomization. End of study is defined as the period starting on the day of week 14 and prior to the week 16 visit. Deaths are treated as the worst outcome and ordering among deaths is based on last value while alive.

Time frame: At baseline and at end of study or death before week 16.

Population: Full Analysis Set: All participants that were randomized, regardless of whether treated or not, including participants from investigator sites having wearable activity monitor data collected.
