• Current Primary Outcome Measures (submitted: February 23, 2018): Change in Peak Oxygen Uptake (VO2) Achieved During Cardiopulmonary Exercise Testing (CPET) From Baseline to Week 24 [ Time Frame: Baseline to Week 24 ]
• Original Primary Outcome Measures (submitted: November 11, 2014): Change in peak oxygen uptake (VO2) from baseline (screening) to Week 24 [ Time Frame: Up to 24 weeks ]

Current Secondary Outcome Measures (submitted: February 23, 2018)

• Change in Peak Oxygen Uptake (VO2) Achieved During Cardiopulmonary Exercise Testing (CPET) From Baseline to Week 12 [ Time Frame: Baseline to Week 12 ]
• Change in Minnesota Living With Heart Failure Questionnaire (MLHFQ) From Baseline to Week 24 [ Time Frame: Baseline to Week 24 ]
  The MLHFQ is a 21-item quality of life (QoL) questionnaire that measures the effects of symptoms, functional limitations, and psychological distress on an individual. Each item is measured on a 6-point Likert scale (0 to 5) and is scored by summing the responses to all 21 questions. Scores range from 0 to 105, with lower scores indicating a better quality of life.

• Change in Treadmill Exercise Time From Baseline to Week 24 [ Time Frame: Baseline to Week 24 ]
  Treadmill exercise time is the time to peak exercise.
• Change in Treadmill Exercise Time From Baseline to Week 12 [ Time Frame: Baseline to Week 12 ]
  Treadmill exercise time is the time to peak exercise.
