Primary Outcome Measures:
  • Number of adverse events [ Time Frame: From screening through Week 64 ]
  • Clinically significant changes in laboratory parameters (complete blood count (CBC), clinical chemistry, and urinalysis) [ Time Frame: From screening through Week 64 ]
  • Clinically significant changes in physical examinations (vital signs, electrocardiogram (ECG), Doppler echocardiography, and liver ultrasound Doppler) [ Time Frame: From screening through Week 64 ]

Secondary Outcome Measures:
  • Maximum concentration (Cmax) [ Time Frame: With the first infusion at 0.3, 1.0 and 3.0 mg/kg and at Week 52 ]
  • Area under the curve until the last measurable concentration (AUClast) [ Time Frame: With the first infusion at 0.3, 1.0 and 3.0 mg/kg and at Week 52 ]
  • Area under the curve extrapolated to infinity (AUC) [ Time Frame: With the first infusion at 0.3, 1.0 and 3.0 mg/kg and at Week 52 ]
  • Half-life (t1/2) [ Time Frame: With the first infusion at 0.3, 1.0 and 3.0 mg/kg and at Week 52 ]
  • Clearance (CL) [ Time Frame: With the first infusion at 0.3, 1.0 and 3.0 mg/kg and at Week 52 ]
  • Volume of distribution (Vss) [ Time Frame: With the first infusion at 0.3, 1.0 and 3.0 mg/kg and at Week 52 ]
  • Change in sphingomyelin levels [ Time Frame: From Day 1 through Week 64 ]
  • Change in sphingomyelin metabolite levels [ Time Frame: From Day 1 through Week 64 ]

Estimated Enrollment: 12

Estimated Study Completion Date: July 2018
Estimated Primary Completion Date: July 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: GZ402665
Olipudase alfa, dose (up to 3.0 mg/kg body weight) once every 2 weeks for 64 weeks
Drug: Olipudase alfa
Pharmaceutical form: powder for concentrate for solution for infusion Route of administration: intravenous infusion
Other Name: GZ402665

Detailed Description:
The maximum study duration per patient is approximately 18 months (screening period: up to 60 days; treatment period: 64 weeks; post-treatment period: up to 37 days, not applicable if patient enrolls in a long term extension treatment trial).

Ages Eligible for Study:   up to 17 Years   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion criteria:

  • The patient and/or patient's parent(s)/legal guardian(s) must provide written informed assent/consent prior to any protocol-related procedures being performed.
  • The patient is aged 0 to <18 years of age on the date of informed assent/consent.
  • The patient has documented deficiency of acid sphingomyelinase as measured in peripheral leukocytes, cultured fibroblasts, or lymphocytes.
  • The patient has a spleen volume ≥5 multiples of normal (MN) measured by magnetic resonance imaging (MRI); patients who have had partial splenectomy will be allowed if the procedure was performed ≥1 year before screening and the residual spleen volume is ≥5 MN.
  • The patient's height is -1 Z-score or lower.
  • A negative serum pregnancy test in female patients of childbearing potential.
  • Female patients of childbearing potential and male patients must be willing to practice true abstinence in line with their preferred and usual lifestyle, or use 2 acceptable effective methods of contraception.

Exclusion criteria:

  • The patient has received an investigational drug within 30 days before study enrollment.
  • The patient has any of the following medical conditions:

    • An active, serious, intercurrent illness.
    • Active hepatitis B or hepatitis C infection.
    • Infection with human immunodeficiency virus (HIV).
    • Cirrhosis (determined by clinical evaluation).
    • Significant cardiac disease (eg, clinically significant arrhythmia, moderate or severe pulmonary hypertension or valvular dysfunction, or <40% left ventricular ejection fraction by echocardiogram).
    • Malignancy diagnosed within the previous 5 years (except basal cell carcinoma).
    • Any other extenuating circumstance that can significantly interfere with study compliance, including all prescribed evaluations and follow-up activities.
  • The patient has acute or rapidly progressive neurological abnormalities.
  • The patient is homozygous for SMPD1 gene mutations R496L, L302P, and fs330 or any combination of these 3 mutations.
  • The patient has a delay of gross motor skills.
  • The patient has had a major organ transplant (eg, bone marrow, liver).
  • The patient requires use of invasive ventilatory support.
  • The patient requires use of noninvasive ventilatory support while awake and for >12 hours a day.
  • The patient, in the investigator's opinion, is unable to adhere to the requirements of the study.
  • The patient has a platelet count <60 × 10^3/µL (based on the average of 2 screening samples obtained up to 24 hours apart).
  • The patient has alanine aminotransferase or aspartate aminotransferase >250 IU/L or total bilirubin >1.5 mg/dL.
  • The patient has an international normalized ratio (INR) >1.5
  • The patient is unwilling or unable to abstain from ingesting alcohol the day before through 3 days after each infusion of olipudase alfa during the treatment period. Measuring alcohol concentration in blood is not required.
  • The patient is scheduled during the study for in-patient hospitalization including elective surgery.
  • The patient requires medication(s) that may can decrease olipudase alfa activity (eg, fluoxetine, chlorpromazine; tricyclic antidepressants [eg, imipramine, or desipramine]).
  • The patient is breast-feeding.
