Detailed Description:

Gaucher disease is characterised by lysosomal accumulation of glucosylceramide due to impaired glucosylceramide hydrolysis. Type 1 Gaucher Disease, the most common form accounts for > 90% of cases and does not involve the central nervous system (CNS). Typical manifestations of type 1 Gaucher Disease include splenomegaly, hepatomegaly, thrombocytopenia, anemia, skeletal pathology and decreased quality of life. The disease manifestations are caused by the accumulations of glucosylceramide (storage material) in Gaucher cells which have infiltrated the spleen and liver as well as other tissue. Eliglustat tartrate (Genz-112638) is a small molecule developed as an oral therapy which acts to specifically inhibit production of this storage material in Gaucher cells.

This study is designed to determine the efficacy, safety, and pharmacokinetics (PK) of eliglustat tartrate (Genz-112638) in adult patients (> 16 years) with Gaucher Disease type 1 The study will consist of 2 periods: The Double-Blind Primary Analysis Period (Day 1 to Week 39) and the Open-Label Period (post-Week 39 [Day 1 of the Open-Label Period] through study completion). After Week 39 assessments are completed, each patient will enter the Open-Label Period where all patients will receive Genz-112638 from post-Week 39 (Day 1 of the Open-Label Period) through study completion. All patients entering in open label period will receive doses of 50, 100 or 150 mg BID based upon plasma levels. The Open-Label Period will include a dose-adjustment period (post-Week 39 to Week 47), a long-term treatment period (Week 48 through study completion which includes a safety follow-up period [30 to 37 days after the patient's last dose of treatment])


Ages Eligible for Study:   16 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • The patient (and/or their parent/legal guardian) is willing and able to provide signed informed consent prior to any study-related procedures to be performed.
  • The patient is at least 16 years old at the time of randomization.
  • The patient has a confirmed diagnosis of Gaucher disease type 1.
  • Female patients of childbearing potential must have a documented negative pregnancy test prior to dosing. In addition all female patients of childbearing potential must use a medically accepted form of contraception throughout the study.

Exclusion Criteria:
