Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change From Baseline in Left Ventricular Mass Indexed to Height (LVMI)		Baseline to 12 months
Primary	Safety Evaluations		Baseline to 12 months
Secondary	Change From Baseline in Maximal Oxygen Consumption (VO2max) at Peak Exercise		Baseline to 12 months
Secondary	Change From Baseline in Distance Walked in 6- Minute Walk Test (6MWT)		Baseline to 12 months
Secondary	Change From Baseline in the Minnesota Living With Heart Failure Questionnaire (MLHF- Q)	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.	Baseline to 12 months
Secondary	Change From Baseline in New York Heart Association (NYHA) Functional Class	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.	Baseline to 12 months
Secondary	Change From Baseline in Plasma Gb3		Baseline to 12 months
Secondary	Change From Baseline in eGFR		Baseline to 12 months
Secondary	Change From Baseline in Albumin/Creatinine (A/Cr) Ratio		Baseline to 12 months
