Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Mean level of urinary Glycosaminoglycan adjusted by the level of urinary creatinine. Timepoint: Visits 9, 11, and 13 (related to the treatment with Aldurazyme®) and visits 21, 23, and final visit (related to the treatment with YW17). Method of measurement: Liquid chromatography tandem mass spectrometry. | — |
Secondary
| Measure | Time frame |
|---|---|
| Distance traveled (based on meters) in 6 minutes (6-minute walk test). Timepoint: Visits 1, 13, and Final. Method of measurement: Timer and meter.;Forced Vital Capacity percentage. Timepoint: Visits 1, 13, and Final. Method of measurement: Spirometer.;Adverse events. Timepoint: At all visits. Method of measurement: All adverse events are assessed through patient reporting, physician diagnosis, and are then classified by severity (based on common terminology criteria for adverse events (CTCAE)), seriousness and relationship to the study drug.;Enzyme assay (a-L-iduronidase activity measurement). Timepoint: Immediately after, half an hour after, and 1.5 hours after the infusion of medicine at visits 12 and 24.
