NCT06406153

Brief 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).
