Clinical Study In Infants With Rapidly Progressive Lysosomal Acid Lipase Deficiency

Detailed Description
Lysosomal acid lipase deficiency is a rare autosomal recessive lipid storage disorder that is caused by a marked decrease or complete absence of the LAL enzyme, leading to the accumulation of lipids, predominately cholesteryl esters and triglycerides, in various tissues and cell types. In the liver, accumulation of lipids in hepatocytes and macrophages leads to hepatomegaly, fibrosis, cirrhosis, liver dysfunction, and hepatic failure. In the small intestine, lipid-laden macrophage accumulation in the lamina propria leads to profound malabsorption.
Lysosomal acid lipase deficiency presenting in infancy is an extremely rare form of the disease characterized by profound malabsorption, growth failure, and hepatic failure that is usually fatal within the first 6 months of life.

- Confirmation of documented decreased LAL activity relative to the normal range of the lab performing the assay or confirmation of LAL-D diagnosis as determined by a Sponsor-approved central laboratory
Substantial clinical concerns, in the opinion of Investigator and Sponsor, of rapid disease progression requiring urgent medical intervention including, but not restricted to the following:
- Marked abdominal distension and hepatomegaly

- Disturbance of coagulation
- Severe anemia
- Sibling with rapidly progressive course of LAL-D
Exclusion Criteria:

EXPERIMENTAL: Open-Label Sebelipase Alfa
All participants initiated once weekly (qw) intravenous (IV) infusions with sebelipase alfa at a dose of 1 milligram/kilogram (mg/kg) qw.
A participant who met protocol defined dose escalation criteria at a dose of 1 mg/kg qw could be considered for a dose escalation to 3 mg/kg qw.
If a participant continued to meet dose escalation criteria after at least 4 infusions at a dose of 3 mg/kg qw, the participant could be considered for a further dose escalation to 5 mg/kg qw.
Under country-specific provisions (United Kingdom only), participants could be considered for a further dose escalation to 7.5 mg/kg qw if a thorough case review indicated that a participant continued to have evidence of disease progression at a dose of 5 mg/kg qw.
All dose escalations were contingent upon acceptable safety and tolerability of preceding infusions and were undertaken by mutual agreement of the Investigator and Sponsor and after approval by an independent safety committee.
|
Sebelipase alfa is a recombinant human lysosomal acid lipase.
The investigational medicinal product is an enzyme replacement therapy intended for treatment of participants with LAL-D.
Dosing occurred once weekly for up to 3 years.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Participants Experiencing Severe Treatment-emergent Adverse Events (TEAEs)
Time Frame: Screening through Month 37
|
The number of participants experiencing severe TEAEs is presented for participants who received sebelipase alfa in this open-label study.
Adverse events were obtained through spontaneous reporting or elicited by specific questioning or examination of the participant's parent or legal guardian.
An adverse event was defined as any new untoward medical occurrence or worsening of a pre-existing medical condition in a participant, whether or not causally related to administration of study drug.
Adverse event severity was graded by the Investigator as mild, moderate, or severe based on definitions developed from Clinical Data Interchange Standards Consortium Study Data Tabulation Model standard terminology v3.1.1.
Adverse events reporting was from the date of informed consent until completion of the follow-up visit at approximately 30 days after the last dose of study drug.
A summary of all serious and other nonserious AEs regardless of causality is located in the Reported AE module.

Secondary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Percentage Of Participants Surviving To 12, 18, 24, And 36 Months Of Age
Time Frame: Baseline through Month 12, Month 18, Month 24, and Month 36
|
The percentage of participants in the FAS who survived to 12, 18, 24, and 36 months of age.
The exact confidence interval was calculated using the Clopper-Pearson method.
Participants with unknown survival status at the age specified in the analysis were excluded.
At 36 months, there were 2 participants who were alive and still on study who had not yet reached the age specified in the analysis.
As such, these participants were excluded from the calculation of percent surviving.
|
Baseline through Month 12, Month 18, Month 24, and Month 36
|
Median Age At Death
Time Frame: Baseline through Month 36
|
Age at death for participants who died during the study.
All deaths were assessed by the Investigator as unrelated to study drug.
|
Baseline through Month 36
|
Change From Baseline In Percentiles For Weight For Age (WFA) At 12, 24, And 36 Months
Time Frame: Baseline, Month 12, Month 24, and Month 36
|
This outcome measure evaluated the effects of sebelipase alfa on growth by measuring the changes from baseline in percentiles for WFA.
Percentiles for WFA were summarized as observed values by visit.
Baseline was defined as the last available assessment prior to the first infusion of sebelipase alfa.

Time Frame: Baseline, Month 12, Month 24, and Month 36
|
This outcome measure evaluated the effects of sebelipase alfa on liver function by measuring the change from baseline in alanine aminotransferase (ALT) and aspartate aminotransferase (AST) at months 12, 24, and 36.
Results are reported in units/liter (U/L).
