What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Observed change in HSEM (ms/deg)

    Change in HSEM from baseline to week 52

    Measured: baseline to week 52

Secondary outcomes (2)
  1. Change in Pineda disability scale score

    Change in the modified Pineda disability scale score. The scale is assessing 4 key domains (manipulation, ambulation, language and swallowing). Individual scores of the domains are claculated ted into a composite score, 6 being the lowest and best score and 24 being the worst and highest score.

    Measured: baseline to week 52

  2. Incidence of treatment-emergent AEs and SAEs

    Treatment-emergent adverse events (AEs) up to 30 days after EOT

    Measured: Baseline to 30 days after End of Treatment (Week 52)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Miglustat in people with Niemann-Pick Disease, Type C, run by Actelion at 2 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Observed change in HSEM (ms/deg) (time frame: baseline to week 52). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03910621, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Mar 2025.
