Clinical Trial Summary

The objective of CLI-06657AA1-04 (formerly PB-102-F60) is to evaluate the long-term safety, tolerability, and efficacy parameters of 1 mg/kg pegunigalsidase alfa administered intravenously every other week in adult Fabry patients who have successfully completed studies PB-102-F03, PB-102-F20 or PB-102-F30.

Description:

This is an open-label study. Patients will be enrolled to receive 1 mg/kg pegunigalsidase alfa as intravenous infusions every 2 weeks (±3 days). The duration of treatment is until pegunigalsidase alfa is commercially available to the patient, or at the discretion of the Sponsor. For the analysis, available efficacy and safety parameters will be summarized using descriptive statistics.
