2018 First Quarter and Recent Clinical Highlights

• Continued enrollment in the three Phase III trials, the BALANCE, BRIDGE and BRIGHT studies, for pegunigalsidase alfa (PRX-102) for the treatment of Fabry disease at nearly 50 clinical trial sites worldwide.
• Testing of blood samples from certain patients screened for the BALANCE study were analyzed for anti-drug antibody (ADA) presence and neutralizing activity, and the cross-reactivity and inhibition of such antibodies to PRX-102.  A description of the data from the analysis has been accepted as a poster presentation scheduled on May 25, 2018 at the 55^th ERA-EDTA Congress (European Renal Association – European Dialysis and Transplant Association) being held in Copenhagen, Denmark, May 24-27, 2018.
