Primary Outcome Measures:
  • The safety of sebelipase alfa in a more broad population of patients with LALD than have been previously studied. [ Time Frame: 30 days after last study drug infusion (up to 144 weeks) ]
    • Incidence of adverse events (AEs), SAEs, and infusion-related reactions (IRRs);
    • Changes from Baseline in 12-lead electrocardiograms (ECGs) and clinical laboratory tests;
    • Changes in vital signs during and after infusion, relative to pre-infusion values;
    • Physical examination findings;
    • Use of concomitant medications/therapies;
    • Characterization of anti-drug antibodies (ADAs);
    • Functional and overall development in patients ≤ 6 years of age will be assessed, as determined by Denver II scores.


Secondary Outcome Measures:
  • The effect of sebelipase alfa on lipid metabolism. [ Time Frame: Baseline to end of treatment period (up to 144 weeks) ]
    • Decrease in LDL-C;
    • Decrease in non-HDL-C;
    • Decrease in triglycerides;
    • Increase in HDL-C

  • The effect of sebelipase alfa on growth parameters in pediatric patients presenting with evidence of growth delay. [ Time Frame: Baseline to end of treatment period (up to 144 weeks) ]
  • The effect of sebelipase alfa on PK parameters. [ Time Frame: Week 0, Week 24, Week 48 ]
    PK parameters include: Cmax, time to maximum concentration, area under the serum concentration vs. time curve from time zero to the last measurable time point, area under the serum concentration vs. time curve from time zero to infinity, terminal elimination half-life, serum clearance, and apparent volume of distribution.

  • The effect of sebelipase alfa on liver function (including histopathology). [ Time Frame: Baseline to end of treatment period (up to 144 weeks) ]
    • Decrease in Child-Pugh status for patients with Child-Pugh class C or B at Baseline;
    • Decreased United Kingdom Model for End-Stage Liver Disease (UK-ELD) score;
    • Improvement in liver histopathology.


Enrollment: 31
Study Start Date: May 2014
Estimated Study Completion Date: December 2017
Estimated Primary Completion Date: December 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: sebelipase alfa
Intravenous infusion of sebelipase alfa: 1mg/kg every other week
Drug: sebelipase alfa
Intravenous infusion of sebelipase alfa: 1mg/kg every other week
Other Name: SBC-102

Detailed Description:
The primary objective of this study is to evaluate the safety of intravenous infusions of sebelipase alfa in a more broad population of LALD patients than previously studied. Such patients may have been excluded from enrollment in other studies of LALD because of age, disease progression, previous treatment by hematopoietic stem cell or liver transplantation, less common disease manifestations, or disease characteristics that would preclude participation in a placebo-controlled study. This open-label study will include infants >8 months, children and adults. Eligible patients will receive sebelipase alfa at a dose of 1 mg/kg every other week.
  Eligibility

Ages Eligible for Study:   8 Months and older   (Child, Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Key Inclusion Criteria:

  1. Patient will be > 8 months of age at the time of dosing.
  2. Confirmation of LALD diagnosis as determined by the central lab.
  3. Patients > 8 months but < 4 years of age at Screening will have at least 1 of the following documented clinical manifestations of LALD:

    Dyslipidemia

    • Elevated transaminases (ALT ≥1.5x ULN)
    • Impaired growth
    • Suspected malabsorption
    • Other clinical manifestation of LALD
  4. Patients ≥ 4 years of age at Screening will have at least 1 of the following documented clinical manifestations of LALD:

    • Evidence of advanced liver disease
    • Histologically confirmed disease recurrence in patients with past liver or hematopoietic transplant
    • Persistent dyslipidemia
    • Suspected malabsorption
    • Other clinical manifestation of LALD

Key Exclusion Criteria:

  1. Patient has known causes of active liver disease other than LALD which have not been adequately treated.
  2. Patient received a hematopoietic stem cell or liver transplant <2 years from the time of dosing.
  3. Patient with co-morbidities other than complications due to LALD which are irreversible or associated with a high mortality risk within 6 months, or would interfere with study compliance or data interpretation.
