Fabry disease (FD) is a rare genetic disorder caused by deficiency in lysosomal enzyme, alpha-galactosidase A (α-Gal A), activity. Pegunigalsidase alfa (PA) is a novel PEGylated α-Gal A enzyme replacement therapy in development for FD. An expanded-access program (EAP) is offered in the US to adults with FD that cannot be adequately managed with approved drugs and who are not eligible for clinical trials. Characterizing patients in an EAP is critical to understanding unmet needs.


We collated baseline characteristics for patients with FD enrolled in the ongoing EAP in the US as of January 1, 2022.


At the data cutoff date, 30 patients had enrolled in the EAP; primarily due to worsening disease symptoms and/or poor tolerability of infusions. There was a mean of 12.9 (SD 11.8) years since diagnosis and most patients had received agalsidase beta treatment (mean duration 7.1 [SD 4.7] years). Median (range) baseline eGFR was 91.4 mL/min/1.73m2 (14.1–131.9) and median concentration (range) of plasma globotriaosylsphingosine was 18.1 nM (0.8–134.6)


Assessment of patients in the PA EAP demonstrated gaps in current treatment options for FD. Some patients had experienced persistent symptoms despite treatment and/or poor tolerability of infusions and may benefit from the PA EAP. Follow-up of clinical outcomes from this EAP will be monitored and presented as data become available.
