  Purpose

Primary Objective:

The primary objective of this phase 2/3 study is to evaluate the efficacy of olipudase alfa (recombinant human acid sphingomyelinase) administered intravenously once every 2 weeks for 52 weeks in adult patients with acid sphingomyelinase deficiency (ASMD) by assessing changes in spleen volume as measured by abdominal magnetic resonance imaging (MRI) and infiltrative lung disease as measured by the pulmonary function test, diffusing capacity of the lung for carbon monoxide.

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 splenomegaly related symptom score from an eDiary after 52 weeks of study drug administration.

To characterize the effect of olipudase alfa after 52 weeks of study drug administration on a symptom based composite score obtained from an eDiary comprising 4 symptom domains (pain, fatigue, dyspnea, and splenomegaly related symptoms).

To characterize the effect of olipudase alfa on liver volume after 52 weeks of study drug administration.

To characterize the effect of olipudase alfa on platelet count after 52 weeks of study drug administration.

Arms Assigned Interventions
Experimental: GZ402665
Olipudase alfa dose (3 mg/kg body weight) in saline administered intravenously once every 2 weeks during the 52 weeks of the primary analysis period for patients randomized to olipudase alfa.
Drug: GZ402665

Pharmaceutical form: Powder for concentrate for solution for infusion administered once every two weeks during the 52 weeks of the primary analysis period for patients randomized to olipudase alfa, and during the extension treatment period for all patients.

Route of administration: intravenous infusion

Other Name: olipudase alfa
Placebo Comparator: Placebo
Placebo (saline) administered intravenously once every 2 weeks during the 52 weeks of the primary analysis period for patients randomized to placebo.
Drug: placebo (saline)

Pharmaceutical form: solution administered once every two weeks during the 52 weeks of the primary analysis period for patients randomized to placebo.

Route of administration: intravenous infusion

Drug: GZ402665

Pharmaceutical form: Powder for concentrate for solution for infusion administered once every two weeks during the 52 weeks of the primary analysis period for patients randomized to olipudase alfa, and during the extension treatment period for all patients.

Route of administration: intravenous infusion

Other Name: olipudase alfa

Detailed Description:

Total duration: at least 3 years and up to 5 years and 3 months Up to two month screening + 52 weeks of primary analysis period + up to 4 years of extension treatment period + 30 to 37 days post last infusion safety follow up.

The study will be divided into 2 consecutive major periods: 1) a randomized placebo-controlled, double-blinded primary analysis period (PAP) from day -60 to week 52, which will be followed by 2) an extension treatment period (ETP) that will last up to 4 years and 1 month and during which all patients will receive olipudase alfa.

  • The patient has diffuse capacity of the lung for carbon monoxide ≤70% of the predicted normal value.
  • The patient has a spleen volume ≥6 multiples of normal (MN) measured by MRI; patients who have had partial splenectomy will be allowed if the procedure was performed ≥1 year before screening/baseline and the residual spleen volume is ≥6 MN.
  • The patient has a mean splenomegaly-related symptom score of at least 5.
  • Female patients of childbearing potential must have a negative serum pregnancy test for beta-human chorionic gonadotropin (β-HCG).
  • Female patients of childbearing potential and 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 for up to 15 days following their last dose of study drug.
