A Safety and Efficacy Study of Fabrazyme® Replacement Therapy in Patients With Cardiac Fabry Disease - Full Text View

Sponsored by:	Genzyme
Information provided by:	Genzyme
ClinicalTrials.gov Identifier:	NCT00140621

Purpose

This is a multi-center, open label, phase IV study conducted to evaluate the efficacy and safety of Fabrazyme [agalsidase beta (recombinant form)] administered by intravenous drip infusion in patients with cardiac Fabry disease.

Patients will participate for 4 weeks or less in the baseline period and 156 weeks for the treatment period.

Primary evaluation variables that will be explored:

Changes in interventricular septum and left ventricular posterior wall thickness from baseline until Week 156 or discontinuation of treatment as assessed by echocardiogram.
Changes in left ventricular mass (LVM) from baseline until Week 156 or discontinuation of treatment as assessed by echocardiogram.

Secondary evaluation variables that will be explored:

Results of overall evaluation of cardiac function assessed by cardiac function tests (echocardiogram, cardiac catheterization (optional), electrocardiogram, brain natriuretic peptide [BNP]), clinical symptoms (subjective symptoms) and the New York Heart Association (NYHA) cardiac functional classification
The mean change and changes in plasma globotriaosylceramide (GL-3) levels
Changes in GL-3 accumulation scores in myocardial tissue from baseline until Week 156 or discontinuation of treatment as assessed by light microscopy
Changes in SF-36 Health Survey scores
Safety evaluation

Adverse events, vital signs, head magnetic resonance imaging (MRI), clinical laboratory data, and immunogenicity will also be explored.

Criteria

Inclusion Criteria:

Patients definitively diagnosed with cardiac Fabry disease (who fulfill all of the following criteria):
- In the case of male patients, documented plasma or leukocyte a- GAL activity is no more than 20% of normal value (except for heterozygous female patients.)
- Left ventricular hypertrophy is noted.
- Accumulation of GL-3 in the myocardium or a genetic deficiency associated with a-GAL has been confirmed
- Or in the case of heterozygous female patients, when the family (father or son) is diagnosed with Fabry disease. (Father or son is related by birth.)
- Without symptoms or signs of Fabry, such as
- acroparesthesia
- angiokeratomas
- abnormal sweating
- pain of distal extremities
- chronic abdominal pain/diarrhea and corneal opacities are observed, except for proteinuria sign.
Patient with interventricular and posterior wall thickness of at least 13 mm on echocardiography within 3 months before signed date to informed consent
Patients in whom cardiac function is rated as Class I or II according to the NYHA classification when giving informed consent.
Patient classification: inpatients and outpatients
Patients who have given written informed consent before the study-related baseline tests.

Exclusion Criteria:

Patient with severe hypertension (e.g., systolic blood pressure 180 mmHg and/or diastolic blood pressure 110 mmHg in spite of adequate medication)
Patients whose serum creatinine level is higher than the upper normal limit within 3 months (12 weeks) prior to giving informed consent.
Patients who have undergone kidney transplantation or are currently on dialysis.
Patients with any serious hepatic disorder. Patients who have abnormal hepatic function test values within 3 months (12 weeks) prior to giving informed consent (when either ALT or AST level exceeds the value five times as high as the upper normal limit).
Permanent pacemaker or defibrillator implanted patients
Pregnant or lactating women
Patients who have taken this drug for 6 months (26 weeks) or more before giving informed consent.
Patients who have participated in a clinical study employing any other investigational product within 3 months prior to giving informed consent.
Enzyme replacement therapy history, except for Fabrazyme.
Patients who are unwilling to comply with the requirements of the protocol.
Others judged by the investigator or sub-investigator to be ineligible for the study
