Official Title: A Phase 2, Open-label Extension Study to Evaluate the Long-Term Safety, Clinical Activity, and Pharmacokinetics of ALN-TTRSC in Patients With Transthyretin (TTR) Cardiac Amyloido

Brief Summary: The purpose of this study was to evaluate the safety and clinical activity of long-term dosing with revusiran (ALN-TTRSC). Dosing has been discontinued; patients are being followed-up for safety.

Detailed Summary:
Sponsor: Alnylam Pharmaceuticals

Current Primary Outcome: Safety and tolerability of long-term dosing with revusiran (ALN-TTRSC) as measured by number of adverse events in patients with transthyretin (TTR) cardiac amyloidosis [ Time Frame: Up to 35 days post last dose ]

Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Assessment of changes from baseline in serum TTR [ Time Frame: From Baseline to Day 1372 ]
  • Mortality [ Time Frame: From Baseline to Day 1344 ]
    Total number of deaths in the study and total number of deaths adjudicated as being related to cardiovascular causes
  • Frequency of cardiovascular-related and heart failure-related hospitalizations [ Time Frame: From Baseline to Day 1344 ]
    The number of times that a subject is hospitalized for cardiovascular- or heart failure- related causes
  • 6-minute walk test performance [ Time Frame: From Baseline to Day 1344 ]
    Change from Baseline to Day 1344 in the total distance walked


Original Secondary Outcome:

  • Assessment of changes from baseline in serum TTR [ Time Frame: From Baseline to Day 700 ]
  • Mortality [ Time Frame: From Baseline to Day 672 ]
    Total number of deaths in the study and total number of deaths adjudicated as being related to cardiovascular causes
  • Frequency of cardiovascular-related and heart failure-related hospitalizations [ Time Frame: From Baseline to Day 672 ]
    The number of times that a subject is hospitalized for cardiovascular- or heart failure- related causes
  • 6-minute walk test performance [ Time Frame: From Baseline to Day 672 ]
    Change from Baseline to Day 672 in the total distance walked
