Eligibility Criteria

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 sexually active 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.
  • Are the trial subjects under 18? yes
  • Number of subjects for this age range: 12
  • F.1.2 Adults (18-64 years) no
  • F.1.2.1 Number of subjects for this age range
  • F.1.3 Elderly (>=65 years) no
  • F.1.3.1 Number of subjects for this age range

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 patients is homozygous for SMPD1 gene mutations R495L, 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 <60,000 /µL (based on the average of 2 screening samples obtained greater than 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 rhASM 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 decrease rhASM activity (eg, fluoxetine, chlorpromazine; tricyclic antidepressants [eg, imipramine, or desipramine]).
  • The patient is breast-feeding.
