Participants will be administered multiple doses of placebo in the double-blind period. In the open-label extension period, participants will be administered multiple doses of patisiran.
Outcomes
Primary Outcome Measures
Change From Baseline at Month 12 in Six-Minute Walk Test (6-MWT)
Distance in meters walked in 6 minutes, longer distances indicate greater functional capacity. Missing 6MWT values due to non-COVID-19 death or inability to walk due to ATTR disease progression were imputed using the worst 10th percentile change observed in the DB period. Missing 6-MWT values due to other reasons are multiply imputed to create 100 complete datasets. The change from baseline is averaged across the 100 complete datasets.
Secondary Outcome Measures
Change From Baseline at Month 12 in Kansas City Cardiomyopathy Questionnaire Overall Summary (KCCQ-OS) Score
The KCCQ is a 23-item self-administered questionnaire quantifying 6 domains (symptoms, physical function, quality of life, social limitation, self-efficacy, and symptom stability) and 2 summary scores (clinical and overall summary [OS]). Scores are transformed to a range of 0-100, in which higher scores reflect better health status.
Composite Endpoint of All-Cause Mortality, Frequency of Cardiovascular (CV) Events (CV Hospitalizations and Urgent Heart Failure [HF] Visits) and Change From Baseline in 6-MWT Analyzed by Win Ratio
The composite endpoint was analyzed using the stratified win ratio method, stratified by baseline tafamidis use. This method combines all-cause mortality, frequency of CV events (CV hospitalizations and HF visits) and change from baseline in 6-MWT in a hierarchical fashion. This method makes within-stratum pairwise comparisons for all patisiran-placebo participant pairs in a sequential manner (first mortality, then CV events, then 6-MWT), with later steps evaluated only in the case of a tie on the prior step. Within each stratum, the win ratio is the total number of 'winners' divided by the total number of 'losers' in the active group. A win ratio >1 represents a favorable outcome for patisiran.
Composite Endpoint of All-Cause Mortality and Frequency of All-Cause Hospitalizations and Urgent HF Visits in Participants Not on Tafamidis at Baseline
The hazard rate of all-cause mortality and all-cause hospitalizations and urgent HF visits will be compared between treatment groups using an Andersen-Gill model. A hazard ratio <1 represents a favorable outcome for patisiran.
Composite Endpoint of All-cause Mortality and Frequency of All-cause Hospitalizations and Urgent HF Visits in All Participants
The hazard rate of all-cause mortality and all-cause hospitalizations and urgent HF visits was compared between treatment groups using a modified Andersen-Gill model. A hazard ratio <1 represents a favorable outcome for patisiran.
