- Application to label a less frequent dosing regimen at a dose of 2 mg/kg body weight administered every four weeks in adult patients with Fabry disease in European Union
PARMA, Italy and CARMIEL, Israel , Dec. 9, 2024 /PRNewswire/ -- Chiesi Global Rare Diseases, a business unit of the Chiesi Group established to deliver innovative therapies and solutions for people living with rare diseases, and Protalix BioTherapeutics, Inc. (NYSE American:PLX), a biopharmaceutical company focused on the development, production and commercialization of recombinant therapeutic proteins produced by its proprietary ProCellEx® plant cell-based protein expression system, today announced that the European Medicines Agency (EMA) has validated the Variation Submission for pegunigalsidase alfa - to label a less frequent dosing regimen at a dose of 2 mg/kg body weight administered every four weeks in adult patients with Fabry disease. The currently approved dose of pegunigalsidase alfa is 1 mg/kg administered every two weeks.
The variation application is supported by a revised Population-PK model and new exposure-response analyses and by the clinical data on pegunigalsidase alfa 2 mg/kg E4W from the completed Phase 3 study PB-102-F50 (BRIGHT) and its ongoing extension study CLI-06657AA1-03 (formerly known as PB-102-F51), that have investigated the 2 mg/kg every four weeks dosing regimen in adult patients with Fabry disease who were previously treated with agalsidase-alfa or -beta administered every two weeks. Results of the completed study PB-102-F50 were recently published in the Journal of Inherited Metabolic Disease.
"The validation of this variation application is an important milestone in our efforts to reduce the burden of treatment for some adult patients living with Fabry disease who continue to experience unmet medical needs," said Giacomo Chiesi, Executive Vice President of Chiesi Global Rare Diseases. "We are committed to delivering innovative therapies and solutions for people living with Fabry disease, their families and caregivers."
"Based on study results, we believe in the potential of pegunigalsidase alfa 2 mg/kg administered every four weeks to be a beneficial, alternative dosing option for some adults living with Fabry disease," said Dror Bashan, Protalix's President and Chief Executive Officer. "Together with Chiesi, we remain committed to meeting the needs of people with Fabry disease and bringing additional therapeutic options to market. We look forward to continuing to work closely with the agency in the months ahead."
