Exhibit 99.1
Protalix BioTherapeutics Reports Positive Preliminary Data from the BRIDGE Study of pegunigalsidase alfa
for the Treatment of Fabry Disease
~Preliminary Results Indicate Improvement in Kidney Function in Patients Switched from
agalsidase alfa (Replagal®) to pegunigalsidase alfa (PRX-102)~
A deterioration trend in patients’ kidney function on agalsidase alfa (Replagal®) was reversed to an
improvement trend when switched to pegunigalsidase alfa (PRX-102)
Presentation with full Data to be held at the1st Canadian Symposium on Lysosomal Diseases 2018
CARMIEL, Israel, September 21, 2018 (GLOBENEWSWIRE) -- Protalix BioTherapeutics, Inc. (NYSE American:PLX) (TASE:PLX), a biopharmaceutical company focused on the development and commercialization of recombinant therapeutic proteins expressed through its proprietary plant cell-based expression system, ProCellEx®, today announced positive preliminary data from the BRIDGE study of pegunigalsidase alfa (PRX-102) for the treatment of Fabry disease. Additional data will be released at the 1st Canadian Symposium on Lysosomal Diseases 2018.
The BRIDGE study is an open label switch over study evaluating the safety and efficacy of PRX-102 in patients with Fabry disease currently treated with agalsidase alfa for at least 2 years and on a stable dose for at least 6 months. Patients are screened and evaluated over 3 months while continuing on agalsidase alfa. Following the screening period, each patient was enrolled and switched from agalsidase alfa treatment to receive intravenous (IV) infusions of PRX-102 1 mg/kg every two weeks for 12 months. Patients can receive PRX-102 infusions at a home care setup based on the infusion tolerability.
Preliminary data from the first sixteen patients enrolled in the trial demonstrated an improvement in kidney function when switched from agalsidase alfa (Replagal®) to pegunigalsidase alfa (PRX-102). Based on available historical serum creatinine and study 3 month screening period values for approximately 2 years while treated with agalsidase alfa before switching to pegunigalsidase alfa treatment, the annualized estimated glomerular filtration rate (eGFR) slope for patients on Replagal was (negative) --6.8ml/min/1.73m2 . The mean eGFR slope for the same patients following six months of treatment with pegunigalsidase alfa (PRX-102) was changed to be (positive) of +3.7ml/min/1.73m2, these results were statistically significant. Baseline characteristic of these patients were: mean estimated glomerular filtration rate (eGFR) 75.40 and 86.03 mL/min/1.73m2 for males and females, with annualized eGFR slope of -8.0 and -5.1 mL/min/1.73m2/year, respectively.
The BRIDGE study is an open-label, single arm switch-over study to assess the safety and efficacy of pegunigalsidase alfa, 1 mg/kg infused every two weeks, in 22 Fabry patients currently treated with Replagal. Protalix anticipates completing patient enrollment in the BRIDGE trial in the fourth quarter of 2018.
PRX-102 is the Company’s plant cell-expressed recombinant, PEGylated, cross-linked α-galactosidase-A for Fabry disease. In pre-clinical and clinical studies, PRX-102 demonstrated higher stability in plasma, a longer half-life and higher exposure in Fabry disease patients, and a reduction in Gb3 in kidney biopsies in treatment naïve Fabry patients.
