Primary Outcome Measures:
  • Incidence of adverse events (AEs) [ Time Frame: Up to 5 years ]
    non-serious AEs, serious AEs, and possible suicidality related AEs

  • Withdrawal from treatment due to AEs [ Time Frame: Up to 5 years ]
    including non-serious and serious AEs

  • Change from baseline in vital signs [ Time Frame: Up to 5 years ]
    blood pressure, heart rate

  • Change from baseline in laboratory parameters [ Time Frame: Up to 5 years ]
    blood chemistry, hematology, urinalysis

  • Change from baseline in electrocardiogram (ECG) [ Time Frame: Up to 5 years ]
    12-lead ECG

  • Change from baseline in echocardiography (ECHO) [ Time Frame: Up to 5 years ]
    ECHO ultrasound

Secondary Outcome Measures:
  • Estimated glomerular filtration rate [ Time Frame: Up to 5 years ]
    based on the Modification of Diet in Renal Disease equation

  • Measurement of 24-hour urine [ Time Frame: Up to 5 years ]
    protein, albumin, creatinine and globotriaosylceramide (GL-3)

  • Evaluation of left ventricular mass index and ejection fraction [ Time Frame: Up to 5 years ]
    as measured by echocardiography

  • Evaluation of leukocyte alpha-galactosidase A (a-Gal A) activity [ Time Frame: Up to 5 years ]
    enzyme responsible for breaking down GL-3

  • Evaluation of patient reported assessment of pain [ Time Frame: Up to 5 years ]
    as assessed by the Brief Pain Inventory short form

  • Evaluation of patient reported Quality of Life [ Time Frame: Up to 5 years ]
    as assessed by the Short Form-36 survey

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   (Child, Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Completed migalastat HCl treatment in a previous Fabry disease protocol
  • Both: both female and male participants are being studied
  • Ages 16 years or older
  • Males and females must agree to use protocol identified acceptable contraception

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
  • Pregnancy or breast feeding
  • Treated with another investigational drug (except migalastat HCl) within 30 days of study start
  • Unable to comply with study requirements, or deemed otherwise unsuitable for study entry, in the opinion of the investigator
  • Has documented transient ischemic attack, stroke, unstable angina, or myocardial infarction within the 12 months before Visit 1
  • Has clinically significant unstable cardiac disease in the opinion of the investigator
  • Has history of allergy or sensitivity to AT1001 (including excipients) or other iminosugars
  • Requires treatment with Glyset, (miglitol), or Zavesca (miglustat)
  • 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.
