Conditions

Acid Sphingomyelinase Deficiency (ASMD)

Brief summary

Primary Objective: To describe the lung, spleen and liver outcomes of olipudase alfa Secondary Objectives: * To describe the patient's characteristics * To describe conditions of olipudase alfa use * To describe safety data related to the use of olipudase alfa * To describe complementary effectiveness outcomes parameters

Detailed description

Approximate duration of enrollment: 30 months Total study duration: approximately 30 months This is a national, multicenter observational retrospective and prospective cohort data collection study. Retrospective is defined as collection of data from all patients, including deceased patients, who were already on early access olipudase alfa in France before the start of this study.

Inclusion criteria

* The patient, or the patient's parent(s)/guardian(s), has signed written informed consent. * Patients with a confirmed diagnosis of ASMD under early access to olipudase alfa in France (ie, nominative compassionate use, pre marketing authorization early access, post marketing authorization early access). * The patient has documented deficiency of acid sphingomyelinase in peripheral leukocytes, lymphocytes, or cultured fibroblasts. * Male and female patients of all ages.

Exclusion criteria

* The patient or legal guardian(s) who has not received information notice or who opposes to data collection. * Patient who died before study initiation and who was opposed to data collection for research purpose when he/she was alive. The above information is not intended to contain all considerations relevant to a potential participation in a clinical trial.

Change in growth curve for pediatric patientFrom baseline at 6, 12, 24 months and every year up to 3 years
Change in weightFrom baseline to 12 months and 36 months
Number of Participants with Evolution of ComorbiditiesFrom baseline to 12 months, 24 months and 36 monthsNumber of participants with evolution of comorbidities will be assessed by grade, attenuation or disappearance/absence
Change in biomarkers (chitotriosidase and lysosphingomyelin) plasma levelsFrom baseline at 3, 6, 9, 12 months and every year up to 3 years
Condition of olipudase alfa useFrom baseline up to 3 yearsConditions of olipudase alfa use (time to reach maximum dose \[3 mg/kg\] or the maximum tolerated dose for the patient, center profile, treater specialty, need of a premedication before the infusion \[if yes, precise\], treatment duration \[start and end dates\], treatment discontinuation \[Yes/No\] and reason of treatment discontinuation if any)
