Registered outcomes2

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimarySafety EvaluationUp to 73 WeeksOverall Safety Summary of Adverse Events (AEs) during Treatment Safety assessment was based on the incidence of AE reports.
SecondaryUrinary Glycosaminoglycan (GAG) ExcretionUp to 73 WeeksPercentage change in the concentration of GAG relative to creatinine in urine (ug GAG/mg creatinine) from baseline to last study visit. Greater decrease indicates greater response.
