- Change From Baseline in Left Ventricular Mass Indexed to Height (LVMI) [ Time Frame: Baseline to 12 months ]
- Safety Evaluations [ Time Frame: Baseline to 12 months ]
- Change From Baseline in Maximal Oxygen Consumption (VO2max) at Peak Exercise [ Time Frame: Baseline to 12 months ]
- Change From Baseline in Distance Walked in 6- Minute Walk Test (6MWT) [ Time Frame: Baseline to 12 months ]
- Change From Baseline in the Minnesota Living With Heart Failure Questionnaire (MLHF- Q) [ Time Frame: Baseline to 12 months ]The MLHF-Q contains 21 questions with answers ranging from 0 (no) to 5 (very much). The final score ( 0 to 105) is the sum of the points for the 21 questions. A higher score indicates a worse quality of life.
- Change From Baseline in New York Heart Association (NYHA) Functional Class [ Time Frame: Baseline to 12 months ]Class I: No limitation of physical activity. Ordinary physical activity does not cause undue fatigue, palpitation, dyspnea. Class II: Slight limitation of physical activity. Comfortable at rest, but ordinary physical activity results in fatigue, palpitation, or dyspnea. Class III: Marked limitation of physical activity. Comfortable at rest, but less than ordinary activity causes fatigue, palpitation, or dyspnea. Class IV: Unable to carry out any physical activity without discomfort. Symptoms of cardiac insufficiency at rest. If any physical activity is undertaken, discomfort is increased.
- Change From Baseline in Plasma Gb3 [ Time Frame: Baseline to 12 months ]
- Change From Baseline in eGFR [ Time Frame: Baseline to 12 months ]
- Change From Baseline in Albumin/Creatinine (A/Cr) Ratio [ Time Frame: Baseline to 12 months ]
