Primary Outcome Measures:
  • Change From Baseline in Left Ventricular Mass Indexed to Height (LVMI) [ Time Frame: Baseline to 12 months ] [ Designated as safety issue: No ]
  • Safety Evaluations [ Time Frame: Baseline to 12 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Change From Baseline in Maximal Oxygen Consumption (VO2max) at Peak Exercise [ Time Frame: Baseline to 12 months ] [ Designated as safety issue: No ]
  • Change From Baseline in Distance Walked in 6- Minute Walk Test (6MWT) [ Time Frame: Baseline to 12 months ] [ Designated as safety issue: No ]
  • Change From Baseline in the Minnesota Living With Heart Failure Questionnaire (MLHF- Q) [ Time Frame: Baseline to 12 months ] [ Designated as safety issue: No ]
    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 ] [ Designated as safety issue: No ]
  • Change From Baseline in Plasma Gb3 [ Time Frame: Baseline to 12 months ] [ Designated as safety issue: No ]
  • Change From Baseline in eGFR [ Time Frame: Baseline to 12 months ] [ Designated as safety issue: No ]
  • Change From Baseline in Albumin/Creatinine (A/Cr) Ratio [ Time Frame: Baseline to 12 months ] [ Designated as safety issue: No ]

Enrollment: 35
Study Start Date: April 2010
Study Completion Date: October 2013
Primary Completion Date: July 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Replagal 0.2 mg/kg EOW
Intravenous, 0.2mg/kg EOW
Biological: Replagal
0.2 mg/kg administered intravenously [IV] every other week
Other Name: Replagal, algalsidase alfa, alpha-Galactosidase

Detailed Description:

HGT-REP-060 was designed to provide patients who participated in TKT028 an additional 52 weeks of treatment with Replagal at the standard dose of 0.2 mg/kg EOW to assess the effect of continued Replagal therapy on long-term safety and clinical outcomes for this patient population.

  Eligibility
