Brief Summary
Primary Objective: The primary objective of this phase 2/3 study was to evaluate the efficacy of olipudase alfa (recombinant human acid sphingomyelinase) administered intravenously once every 2 weeks for 52 weeks in adult participants with acid sphingomyelinase deficiency (ASMD) by assessing changes in: 1) spleen volume as measured by abdominal magnetic resonance imaging (MRI) (and, for the United States \[US\] only, in association with participant perception related to spleen volume as measured by splenomegaly-related score \[SRS\]); and 2) infiltrative lung disease as measured by the pulmonary function test, diffusing capacity of the lung for carbon monoxide (DLCO). Secondary Objectives:
- To confirm the safety of olipudase alfa administered intravenously once every 2 weeks for 52 weeks.
- To characterize the effect of olipudase alfa on the participant perception related to spleen volume as measured by the SRS after 52 weeks of study drug administration. (For the US, the effect of olipudase alfa on the SRS is part of the primary objective).
- To characterize the effect of olipudase alfa after 52 weeks of study drug administration on the following outcome measures assessed sequentially:
- The effect of olipudase alfa on liver volume;
- The effect of olipudase alfa on platelet count;
- The effect of olipudase alfa on fatigue;
- The effect of olipudase alfa on pain;
- The effect of olipudase alfa on dyspnea.

Outcome Measures
Primary Outcomes (6)
Percent Predicted (% Predicted) Hemoglobin (Hb) and Altitude-Adjusted Diffusing Capacity of the Lung for Carbon Monoxide (DLco) at Baseline
Percent predicted Hb and Altitude-adjusted DLco was calculated as: 100\*Adjusted DLco/Predicted DLco in unit of mL CO/min/mmHg where, adjusted DLco = Observed DLco (in mL CO/min/mmHg) times Hemoglobin-adjusted factor times Altitude-adjustment factor.
Baseline (Day 1)
Percent Change From Baseline in Percent Predicted (% Predicted) Hemoglobin (Hb) and Altitude-Adjusted Diffusing Capacity of the Lung for Carbon Monoxide (DLco) at Week 52
Percent predicted Hb and Altitude-adjusted DLco was calculated as: 100\*Adjusted DLco/Predicted DLco in unit of mL CO/min/mmHg where, adjusted DLco = Observed DLco (in mL CO/min/mmHg) times Hemoglobin-adjusted factor times Altitude-adjustment factor.
Baseline, Week 52
Combination Spleen Endpoint: Component 1: Spleen Volume (in MN) at Baseline
Spleen volume was assessed by abdominal magnetic resonance imaging (MRI) to quantitate the degree of splenomegaly in multiples of normal (MN).
Baseline (Day 1)
Combination Spleen Endpoint: Component 1: Percent Change From Baseline in Spleen Volume (in MN) at Week 52
Spleen volume was assessed by abdominal MRI to quantitate the degree of splenomegaly in MN.
Baseline, Week 52
Combination Spleen Endpoint (Primary for US Only): Component 2: Splenomegaly-Related Score (SRS) at Baseline
The SRS rates 5 items: abdominal pain, abdominal discomfort, early satiety, dissatisfaction with abdominal body image, and difficulty to bend down using a numerical rating scale of 0 (absent) to 10 (worst imaginable). The total score of SRS ranges from 0 to 50, with higher scores (50) indicated worst imaginable rating. It was pre-specified as secondary endpoint for countries outside of US.
