Efficacy and Safety of YW17 (Laronidase-CinnaGen) Compared to Aldurazyme® in MPS I Patients

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)"

Summary

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).

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.
