Summary
Brief summary
This is the first human treatment with PRX-102, an enzyme being developed as a long-term enzyme replacement therapy in patients with a confirmed diagnosis of Fabry disease (alpha galactosidase deficiency). The safety, tolerability, and exploratory efficacy will be evaluated in this study of increasing doses. Patients will be treated with infusions every two weeks for 12 months.
