Summary

This study followed 3 people with acid sphingomyelinase deficiency (ASMD) who had already completed earlier trials of olipudase alfa. The goal was to monitor safety and side effects while they continued receiving the enzyme replacement therapy every two weeks until the drug was officially available in France. The study focused on adverse events and serious adverse events.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
olipudase alfa (enzyme replacement therapy)
What this could lead to
If successful, this could confirm that long-term use of olipudase alfa is safe and tolerable for people with acid sphingomyelinase deficiency.
What could go wrong
This is a very small study (3 people) and only looked at safety, not how well the drug works. It may not apply to all patients.

Inclusion Criteria: * The participant has completed Study DFI12712 (ASCEND) or LTS13632 in France * The participant must provide signed, informed consent prior to performing any study-related procedures. * The participant was willing to comply with the clinical protocol. * The participant, if female and of childbearing potential, must have had a negative pregnancy test result \[urine beta-human chorionic gonadotropin (β-HCG)\] at enrollment. * Sexually active female participants of childbearing potential and male participants were required to practice true abstinence in line with their preferred and usual lifestyle or to use 2 acceptable effective methods of contraception for the entire duration of the treatment period and for at least 28 days after receiving the last study drug dose. Exclusion Criteria: Participants are excluded from the study if any of the following criteria apply: * Any participant who has not participated in the Study DFI12712 or the Study LTS13632 * A participant who experienced any systemic hypersensitivity reactions to olipudase alfa in Study DFI12712 or Study LTS13632 which, in the opinion of the Investigator, could indicate that treatment continuation may present an unreasonable risk. * The participant, in the opinion of the Investigator, is unable to adhere to the requirements of the study. * The participant was unwilling or unable to abstain from alcohol for 1 day prior to and 3 days after each olipudase alfa infusion for the duration of the treatment period. * Individuals accommodated in an institution because of regulatory or legal order; prisoners or participants who were legally institutionalized. * The participant was concurrently participating in another clinical study of investigational treatment. * Any of the following medical conditions: * The participant has had any new condition or worsening of an existing condition which, in the opinion of the Investigator, would make the participant unsuitable for enrollment or could interfere with the participant's participating in or completing the study. * Requirement for recurrent dose adjustment of anticoagulation treatment over the last 6 months. * Pregnancy or breastfeeding. The above information is not intended to contain all considerations relevant to a participant's potential participation in a clinical trial.
