Primary Outcome Measures:
  • Incidence of adverse events (AEs) [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]
    non-serious AEs, serious AEs, and possible suicidality related AEs

  • Withdrawal from treatment due to AEs [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]
    including non-serious and serious AEs

  • Change from baseline in vital signs [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]
    blood pressure, heart rate

  • Change from baseline in laboratory parameters [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]
    blood chemistry, hematology, urinalysis

  • Change from baseline in electrocardiogram (ECG) [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]
    12-lead ECG

  • Change from baseline in echocardiography (ECHO) [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]
    ECHO ultrasound

Secondary Outcome Measures:
  • Estimated glomerular filtration rate [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]
    based on the Modification of Diet in Renal Disease equation

  • Measurement of 24-hour urine [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]
    protein, albumin, creatinine and globotriaosylceramide (GL-3)

  • Evaluation of left ventricular mass index and ejection fraction [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]
    as measured by echocardiography

  • Evaluation of leukocyte alpha-galactosidase A (a-Gal A) activity [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]
    enzyme responsible for breaking down GL-3

  • Evaluation of patient reported assessment of pain [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]
    as assessed by the Brief Pain Inventory short form

  • Evaluation of patient reported Quality of Life [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]
    as assessed by the Short Form-36 survey

Other Name: AT1001

Detailed Description:

AT1001-041 is an open-label, non-comparative, multicenter, long term extension study for subjects with Fabry disease who have completed treatment in a previous trial of migalastat HCl (also known as AT1001) given as monotherapy. This is an extension study designed to evaluate the long-term safety and efficacy of migalastat HCl for the treatment of Fabry disease. Study visits will occur every 6 months to evaluate safety and assess efficacy. Visit evaluations will include physical examination, clinical laboratory parameters, adverse events and patient reported outcomes.


Ages Eligible for Study:   16 Years and older
Genders Eligible for Study:   Both

Exclusion Criteria:

  • Estimated glomerular filtration rate in the previous study was <30 mL/min/1.73m2; unless there is measured GFR available within 3 months of Baseline Visit (Visit 1), which is >30 mL/min/1.73m2
  • Has undergone, or is scheduled to undergo kidney transplantation or is currently on dialysis

  • Has any intercurrent illness or condition that may preclude the subject from fulfilling the protocol requirements
  • Patients with severe or unsuitable concomitant medical condition
  • Patients with clinically significant abnormal laboratory value(s) and clinically significant electrocardiogram (ECG) findings at baseline.
