Brief Summary:
The objective of PB-102-F51 is to evaluate the long-term safety, tolerability, and efficacy of 2 mg/kg pegunigalsidase alfa administered intravenously every four weeks in adult Fabry patients who have successfully completed PB-102-F50.

Condition or disease Intervention/treatment Phase
Fabry Disease Biological: pegunigalsidase alfa Phase 3

Detailed Description:
This is an open-label study to assess the long-term safety and efficacy of pegunigalsidase alfa treatment of 2.0 mg/kg administered intravenously every 4 weeks. The duration of treatment will be up to 48 months or until pegunigalsidase alfa is available to the patient at the discretion of the Sponsor. Interim analyses may be performed for administrative purposes during the conduct of the study.
