Last updated: May 24, 2012
Last verified: May 2012
  Purpose

Although miglustat has been approved as a treatment for mild to moderate type 1 Gaucher disease in patients who are unsuitable for enzyme replacement therapy (ERT), more data are required to establish the long term efficacy, safety and tolerability of miglustat in maintaining diseases stability after a switch from ERT.


Condition Intervention Phase
Type 1 Gaucher Disease
Drug: miglustat
Phase 3

Study Type: Interventional
Study Design: Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Open-label, Non Comparative, Multi-center Study to Evaluate the Long Term Efficacy, Safety and Tolerability of Oral Miglustat as a Maintenance Therapy After a Switch From Enzyme Replacement Therapy in Adult Patients With Stable Type 1 Gaucher Disease

Primary Outcome Measures:
  • Liver Volume [ Time Frame: baseline to end of treatment (month 24 or imputed value) ] [ Designated as safety issue: No ]
    Liver volume was assessed at baseline and end of treatment by magnetic resonance imaging

  • Percent Change in Liver Volume [ Time Frame: baseline to end of treatment (month 24 or imputed value) ] [ Designated as safety issue: No ]
    Liver volume was assessed at baseline and end of treatment by magnetic resonance imaging


Secondary Outcome Measures:
  • Spleen Volume [ Time Frame: baseline to end of treatment (month 24 or imputed value) ] [ Designated as safety issue: No ]
    Spleen volume was assessed at baseline and end of treatment by magnetic resonance imaging

  • Percent Change in Spleen Volume [ Time Frame: baseline to end of treatment (month 24 or imputed value) ] [ Designated as safety issue: No ]
    Spleen volume was assessed at baseline and end of treatment by magnetic resonance imaging

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Males or females aged 18 years or older
  2. Type 1 Gaucher disease, diagnosed by glucocerebrosidase assay or molecular analysis of the glucocerebrosidase gene.
  3. Treatment with ERT for at least 3 years, with a stable dose regimen for at least the last 6 months.
  4. Clinically and biologically stable disease for the previous 2 years, with at least 2 time points assessments (including Baseline as one potential time point), defined as:

    • Stable organomegaly (assessed by magnetic resonance imaging (MRI) or computed tomography (CT)):

      • Liver volume within 10% of the mean.
      • Spleen volume within 10% of the mean.
    • Free of progressive symptomatic documented bone disease.
    • Hemoglobin levels > 11g/dl
    • Mean platelet count > 100x109 /l.
    • Chitotriosidase activity within 20% of the mean. - If chitotriosidase is not available (in the case of chitotriosidase deficiency, or if it was not determined), other relevant biomarkers (e.g., angiotensin converting enzyme (ACE), tartrate resistant acid phosphatase (TRAP) and ferritin) could be considered.
  5. Written informed consent.

Exclusion Criteria:

  1. History or evidence of oculomotor gaze palsy, ataxia or other clinical manifestations typically associated with neuronopathic type 3 Gaucher disease.
  2. Not ambulant patients, or with progressive symptomatic documented bone disease.
  3. Splenectomy before 18 years of age for splenomegaly and/or thrombocytopenia.
  4. Peripheral polyneuropathy (not mononeuropathy) documented with both clinical signs and symptoms, and electrodiagnostic (EDX).
  5. Patients (males and females) who do not agree to use reliable contraception throughout the study and for 3 months after cessation of miglustat treatment.
  6. Female patients who are pregnant or breast feeding, or without pregnancy test prior to Day 1.
  7. History of significant lactose intolerance.
  8. Clinically significant diarrhea (>3 liquid stools per day for >7 days) without definable cause within 6 months prior to Day 1, or a history of clinically relevant gastrointestinal disorders.
  9. History of cataracts or known increased risk of cataract formation.
  10. Severe renal impairment i.e., with a creatinine clearance <30 ml/min/1.73m^2
  11. Concomitant active medical condition such as human immunodeficiency virus (HIV) or hepatitis B/C that would render patients unsuitable for study.
  12. Previous treatment with miglustat.
