Brief Summary

Gaucher disease is a genetic disease that results in a deficiency of an enzyme acid beta-glucosidase, also known as glucocerebrosidase. This enzyme is needed to digest a substrate (lipid) called glucosylceramide and, to a lesser degree, glucosylsphingosine. In participants with Gaucher disease, the liver, spleen, bone marrow and brain show increases in lipid concentration, specifically in cells derived from the monocyte/macrophage system. Eliglustat tartrate (Genz-112638) is an oral drug that may regulate the Gaucher disease process by decreasing the synthesis of glucosylceramide. The primary objective of this study is to evaluate the efficacy, safety and pharmacokinetics (PK) of eliglustat tartrate, administered as an oral dose of either 50 milligram (mg) twice daily (BID) or 100 mg BID, to men and women with Gaucher disease Type 1 for 52 weeks.

Outcome Measures

Primary Outcomes (1)

• Percentage of Participants Demonstrating A Meaningful Clinical Response

  A meaningful clinical response was defined as an improvement in at least 2 of the 3 main efficacy parameters: a) an increase in hemoglobin of greater than or equal to (\>=) 0.5 gram/deciliter from baseline, b) an increase in platelets of \>=15 percent (%) from baseline, c) reduction in total spleen volume of \>= 15% from baseline. As hemoglobin, platelets, total spleen volume were abnormal at baseline, within each participant, only those parameters were used in the evaluation of meaningful clinical response which were abnormal at baseline.

  Baseline, Year 1

• Percent Change From Baseline in Spleen Volume at Year 1, Year 2, Year 3, Year 4, Year 5, Year 6, Year 7, Year 8, Year 9 and at End of Study

  Baseline, Year 1, Year 2, Year 3, Year 4, Year 5, Year 6, Year 7, Year 8, Year 9 and at End of Study (Up to Year 9)

• Absolute Change From Baseline in Hemoglobin at Year 1, Year 2, Year 3, Year 4, Year 5, Year 6, Year 7, Year 8, Year 9 and at End of Study

  Baseline, Year 1, Year 2, Year 3, Year 4, Year 5, Year 6, Year 7, Year 8, Year 9 and at End of Study (Up to Year 9)

Study Arms (1)

Eliglustat tartrate

EXPERIMENTAL

Drug: Eliglustat tartrate

Interventions

Eliglustat tartrate DRUG

Eliglustat (Genz-112638) capsule as single 50 mg dose on Day 1 then eliglustat 50 mg twice daily (BID) from Day 2 to Day 19, then either eliglustat 50 mg BID (if Genz-99067\[active moiety of eliglustat in plasma\] trough plasma concentration was greater than or equal to \[\>=\]5 nanogram per milliliter \[ng/mL\] on Day 10) or eliglustat 100 mg BID(if Genz-99067 trough plasma concentration was less than \[\<\] 5 ng/mL), from day 20 to Year 4. After primary completion date (Week 52) participants underwent treatment interruption period of approximately 2 weeks before continuing same treatment through study completion (Year 9). Participant receiving 100 mg BID could be considered for further dose increase to 150 mg BID at Week 24 if they met certain criteria (for example, had been on treatment for at least 24 months, had not reached therapeutic goals established for participants receiving Cerezyme, and if all other causes for lack of treatment effect had been evaluated and ruled out).

Also known as: Genz-112638

Eligibility Criteria

• Age: 18 Years - 65 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• The participant had a diagnosis of Gaucher Type I disease and a documented deficiency of glucocerebrosidase activity by enzyme assay and was willing and able to provide written informed consent prior to initiating any study-related procedures;
• The participant was 18 to 65 years old and weighed between 50 and 120 kilogram (kg) at enrollment;
• The participant had the following symptoms of Gaucher disease identified within 28 days of enrollment (at screening);
• Anemia - indicated by hemoglobin measurements taken during the screening phase (8 to 10 gram per deciliter (g/dL) if female, 8 to 11 g/dL if male);
• Thrombocytopenia - indicated by platelet count measurements taken during the screening phase (60000 to 100000 per cubic millimeter);
• Splenomegaly, as indicated by magnetic resonance imaging (MRI) or spiral computed tomography (CT) (\>= 10 multiples of normal);
• Female participants of child-bearing potential must had a documented negative serum pregnancy test prior to dosing. Female participants agreed to use a reliable method of birth control throughout duration of trial.

You may not qualify if:

• Participant had a partial or total splenectomy or infarcted areas of the spleen;
• Participant had documented prior bleeding varices or liver infarction;
• Participant received miglustat within 12 months prior to study enrollment;
• The participant had received an investigational product within 30 days prior to study enrollment;
• Participant had neurologic or pulmonary involvement;
• Participant had new pathological bone involvement or bone crisis in the 12 months prior to enrollment;
• Participant was transfusion-dependent;
• Participant had a documented etiology of anemia due to causes other than Gaucher disease;
• The participant had cardiac functional and/or anatomical abnormalities, a history of cancer or tested positive for human immunodeficiency virus (HIV) antibody or Hepatitis;
• Participant had a clinically significant disease, other than Gaucher disease, including cardiovascular, renal, hepatic, gastrointestinal, pulmonary, neurologic, endocrine, metabolic, or psychiatric disease, other medical conditions, or serious intercurrent illnesses that, in the opinion of the Investigator, might preclude participation in the study.
