About this study

Official title: A Phase III, Single Arm, Cross-over, Multicenter Clinical Trial to Compare Efficacy and Safety of YW17(Laronidase; CinnaGen) Versus Laronidase (Aldurazyme®; Genzyme, BioMarin) in Patients With Mucopolysaccharidosis Type I (MPS I)"

The purpose of this phase III study is to assess the efficacy and safety of YW17 produced by CinnaGen Company compared to Aldurazyme® in mucopolysaccharidosis type I (MPS I) patients.

All patients receive Aldurazyme® for 12 weeks, followed by YW17 for another 12 weeks.

The primary outcome is the assessment of the maintenance of the mean uGAG levels at the end of each medication administration. The secondary outcomes are the assessment of 6-minute walking test (6MWT), predicted forced vital capacity (FVC), enzyme activity assay, and adverse events (AEs).

Read the detailed description

This is a phase III, single-sequence, cross-over study to assess the efficacy and safety of YW17 produced by CinnaGen Company in comparison with Aldurazyme® in MPS I patients.

All patients receive 0.58 mg/kg of Aldurazyme® for 12 weeks and then receive 0.58 mg/kg of YW17 for another 12 weeks.

Premedication with antipyretics and/or antihistamines is administered for all patients one hour before the infusion.

The primary outcome is to compare the mean uGAG levels at weeks 8, 10, and 12 (related to Aldurazyme®) with the mean uGAG levels at weeks 20, 22, and 24 (related to YW17).

The secondary outcomes, including 6MWT and FVC are assessed at the beginning and the end of each medication administration. Enzyme activity is assessed at the end of each medication administration. Safety assessments are performed during the study.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • LaronidaseBiological

    Laronidase as Aldurazyme® (the first 12 weeks) or YW17 (the second 12 weeks) is administered.

  • AntihistamineDrug

    An antihistamine is administered one hour before the infusion.

  • AntipyreticDrug

    An antipyretic is administered one hour before the infusion.

What is being measured

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

  1. mean uGAG

    urinary glycosaminoglycan

    Measured: Baseline, weeks 8, 10, 12, 20, 22, and 24

Secondary outcomes (4)
  1. mean 6MWT

    6-minute walking test

    Measured: Baseline, week 12, week 24

  2. mean predicted FVC

    Forced vital capacity

    Measured: Baseline, week 12, week 24

  3. mean enzyme activity level

    Enzyme activity assay

    Measured: Weeks 11 and 23

  4. Number of participants with adverse events

    All reported AEs are classified based on the Medical Dictionary for Regulatory Activities (MedDRA) terms and are graded according to the Common Terminology Criteria for Adverse Events (CTCAE) v5.0.

    Measured: During the study period (screening visit up to week 24)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Laronidase, Antihistamine and Antipyretic in people with Mucopolysaccharidosis Type 1, run by Cinnagen at 4 sites in Iran.

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 3 inclusion and 10 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 6 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Iran. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

mean uGAG (time frame: Baseline, weeks 8, 10, 12, 20, 22, and 24). 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 NCT06406153, 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 6 Aug 2024.
