    Arm description
    This subgroup is part of the full analysis set and includes only participants between the ages of 2 and 4 years old who initiated intravenous (IV) treatment with sebelipase alfa at a dose of 1 milligram/kilogram (mg/kg) every other week (qow). Participants were considered for a dose adjustment at the discretion of the Investigator and in consultation with the Sponsor. Dose escalation to 3 mg/kg qow was considered if pre-defined dose-escalation criteria were met. If these criteria continued to be met, a subsequent dose escalation to 3 mg/kg every week (qw) was considered. Dose decreases as low as 0.35 mg/kg qow were permitted based upon evidence of intolerance to sebelipase alfa treatment. Participants who completed the 96-week treatment period were permitted to continue receiving sebelipase alfa in an expanded treatment period for up to 48 weeks, pending local drug availability and study participation status.

    Participants Experiencing Severe Treatment-emergent Adverse Events (TEAEs) [1]
    End point description
    The number of participants experiencing severe TEAEs is presented for each age group who received sebelipase alfa in this open-label study. Information on AEs was obtained at each scheduled contact with the participant (or participant’s parent or legal guardian), by specific questioning and, as appropriate, by examination. An AE was defined as any untoward medical occurrence in a participant that did not necessarily have to have a causal relationship with the administration of the study drug. An AE therefore could have been any unfavorable and unintended sign, symptom or disease temporally associated with the use of the study drug, whether or not considered related to the medicinal product. Pre-existing conditions that worsened in severity during the course of the study were reported as AEs. AEs were recorded from the date of informed consent until completion of the follow-up phone call at 4 weeks after the last infusion of sebelipase alfa administered.

    Percent Change In Serum Lipids From Baseline To Week 144
    End point description
    The effect of sebelipase alfa on lipid metabolism was evaluated by measuring the change from baseline to Week 144 in 4 serum lipids: low-density lipoprotein cholesterol (LDL-C); high-density lipoprotein cholesterol (HDL-C); non-HDL-C; triglycerides. Blood samples for these clinical laboratory tests were collected at scheduled time points and analyzed by a central laboratory.

    Participants Testing Positive For Anti-drug Antibodies (ADAs)
    End point description
    The impact of ADAs on the safety and immunogenicity of sebelipase alfa was evaluated by testing for ADAs in participants who received sebelipase alfa in this open-label study. Blood samples for assessment were collected prior to study infusions at Week 2, Week 4, Week 8, Week 12, and every 12 weeks thereafter. Participants testing positive for ADAs were also tested for the presence of neutralizing antibodies that inhibited sebelipase alfa enzyme activity and/or cellular uptake. Any participant experiencing a moderate or severe infusion-associated reaction (IAR) was to have an additional assessment of ADAs at the next study visit (prior to study drug infusion); these participants were to also have serum samples collected at 1 to 2 hours after IAR onset and at the next study visit (prior to study drug infusion) for analysis of serum tryptase. The number of participants who became ADA positive and who tested positive for neutralizing antibodies are presented.

    Percent Change In Body Mass Index (BMI)-For-Age Percentile From Baseline To Week 144 in Pediatric Participants
    End point description
    To evaluate the effects of sebelipase alfa on growth parameters in pediatric participants (≤18 years old) presenting with evidence of growth delay, the percent change in the anthropometric parameter of BMI-for-age percentile from Baseline to Week 144 is reported. Anthropometric parameters were plotted on standard growth curves. When possible, historical data on growth parameters was also incorporated into the analyses. Percentiles and Z-scores for BMI-for-age were determined using standard growth charts appropriate to a participant’s age on the date of the assessment: the World Health Organization standard growth chart for participants ≤2 years of age and the Centers for Disease Control standard growth chart for participants >2 years of age.

    Shift In Child-Pugh Status From Baseline To Week 144
    End point description
    In order to evaluate the effects of sebelipase alfa on liver function, the number of participants with a shift in Child-Pugh status from Baseline to Week 144 is reported. The status is based on the Child-Pugh score, which is used in clinical practice to assess prognosis in individuals with chronic liver disease. Laboratory data were used in derivation of the score by summing individual scores (scored 1–3, with 3 indicating most severe) from clinical laboratory test results and physical examinations, including total serum bilirubin, serum albumin, prothrombin time, ascites, and hepatic encephalopathy. The total score was used to determine the Child-Pugh status, reported as Class A (score of 5 or 6), Class B (score of 7 to 9), or Class C (score of 10 to 15). Higher scores and higher categories represented a worse outcome. Data reported as 1 of 2 types of shifts in class: No Change from Baseline; Decline from Baseline.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    02 Feb 2015
    − Removed ‘seroconversion rate’ and ‘time to seroconversion’ from the immunogenicity outcome variables. The intent was to characterize ADAs for all isotypes. In this study, a participant was considered to be ADA positive if they had at least 1 positive ADA titer at any time during the study. However, a single positive ADA result would not necessarily imply that a participant had seroconverted. Moreover, analysis of tolerization (for which no standard definition exists) would not be appropriate to these circumstances. − Limited liver biopsy by the transjugular method to participants with advanced liver disease (as local facilities permitted), rather than recommending this for all study participants. − Updated the guidance on the management of IARs based on clinical experience in other ongoing studies with sebelipase alfa. − Clarified that AEs collected during hospitalization would be assessed and reported. − Clarified that AEs occurring after signing the informed consent but before the first dose of study drug would only be recorded if deemed related to study procedures or requirements.
    07 Dec 2015
    - Clarified that the minimum duration of treatment would be “at least 52 weeks.” This clarification was added in response to Pediatric Committee comments on the paediatric investigation plan request for modification. - Added a pharmacokinetics (PK) profile for participants receiving a dose decrease (the protocol already required a PK profile for participants receiving a dose increase), and added an ADA assessment prior to the first infusion at the new dose for all participants receiving a dose modification (increase or decrease). These additional data will support an evaluation of the relationship between immunogenicity, sebelipase alfa exposure, and clinical response during long-term treatment with sebelipase alfa.

    Interruptions (globally)
