| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| Evaluate the safety and pharmacokinetics of eliglustat in pediatric patients (≥6 to <18 years old). |
|
| E.2.2 | Secondary objectives of the trial |
| Evaluate the efficacy of eliglustat and quality of life in pediatric patients (≥6 to <18 years old). |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
-The patient is 6 to <18 years old at the time of informed consent.
-Male and female patients with a clinical diagnosis of Gaucher disease (GD) type 1 or type 3 with documented deficiency of acid beta-glucosidase activity by enzyme assay and glucocerebrosidase (GBA) genotype.
-Postmenarchal female patients must have a documented negative pregnancy test prior to enrollment and throughout the study. Patients must be willing to practice true abstinence in line with their preferred and usual lifestyle, or use a medically accepted form of contraception throughout the study.
Cohort 1 (Eliglustat monotherapy):
-Patients must have been receiving an enzyme replacement therapy (ERT) for a minimum of 24 months at a monthly dose equivalent to 30 U/kg to 130 U/kg of Cerezyme® (imiglucerase) with treatment ongoing at the time of enrollment. Patients must be at pre-specified treatment goals, as defined by:
-Hemoglobin level for ages 6 to <12 years: ≥11.0 g/dL; for ages 12 to <18 years: ≥11.0 g/dL for females and ≥12.0 g/dL for males;
-Platelet count ≥100,000/mm3;
-Spleen volume <10.0 multiples of normal (MN);
-Liver volume <1.5 MN;
-Absence of GD related pulmonary disease, and severe bone disease, as defined below for Cohort 2.
Cohort 2 (Eliglustat plus imiglucerase):
-Patients must have been receiving an ERT for a minimum of 36 months at a dose equivalent to at least 60 U/kg of imiglucerase every 2 weeks at the time of enrollment with treatment ongoing at the time of enrollment and the dose stable for at least the 6 months preceding enrollment. Patients must have severe clinical manifestations of GD, as defined by the presence of at least of the
following:
-GD related pulmonary disease such as interstitial lung disease (ILD). The diagnosis of ILD must be confirmed by the presence of reticulonodular densities on chest X-ray.
AND/OR
-Symptomatic bone disease characterized by pathological fracture, osteonecrosis,
osteopenia/osteoporosis, or bone crisis occurring in the 12 months prior to enrollment.
AND/OR
-Persistent thrombocytopenia (<80,000/mm3) related to GD. |
|
| E.4 | Principal exclusion criteria |
-Substrate reduction therapy for GD within 6 months prior to enrollment
-Partial or total splenectomy if performed within 2 years prior to enrollment
-The patient is transfusion dependent, a history of esophageal varices or liver infarction, elevated liver enzymes, significant congenital cardiac defect, coronary artery disease or left sided heart failure; clinically significant arrhythmias or conduction defect such as Type 2 second degree or third degree atrioventricular (AV) block, complete bundle branch block, prolonged QTc interval, or sustained ventricular tachycardia (VT).
-The patient has any clinically significant disease other than GD.
-The patient has neurological symptoms other than oculomotor apraxia at study entry.
-The patient has received an investigational product within 30 days prior to enrollment.
-The patient is unable to receive treatment with imiglucerase due to a known hypersensitivity or is unwilling to receive imiglucerase treatment every 2 weeks.
-The patient has a known hereditary galactose intolerance, Lapp lactase deficiency or glucose galactose malabsorption, or is a CYP2D6 ultra-rapid metabolizer or indeterminate metabolizer. |
