BLA Submission Expected First Quarter 2020
CARMIEL, Israel, June 06, 2019 (GLOBE NEWSWIRE) -- Protalix BioTherapeutics, Inc. (NYSE American: PLX) (TASE: PLX), or Protalix, and Chiesi Farmaceutici S.p.A, an international research-focused healthcare Group, or Chiesi, today announced that, following a series of meetings and correspondence with the U.S. Food and Drug Administration (FDA), they plan to file a biologics license application, or a BLA, for pegunigalsidase alfa for the treatment of Fabry disease in the first quarter of 2020 via the FDA’s Accelerated Approval pathway.
Over the last several months, Protalix and Chiesi have engaged the FDA in a dialogue regarding the potential eligibility of pegunigalsidase alfa for accelerated approval based on readily available data generated by Protalix from its clinical studies of pegunigalsidase alfa.
As a result of this dialogue and a recent letter received from the FDA, Protalix and Chiesi have initiated preparations for a BLA submission based on data from the completed phase I/II clinical trials of pegunigalsidase alfa and from the ongoing phase III BRIDGE clinical trial. Protalix and Chiesi are targeting a BLA submission for the first quarter of 2020.
If approved, Protalix will be eligible to receive a milestone payment from Chiesi.
“We are very excited to be one step closer to an approved product to help a patient population that desperately needs a better option than those currently available on the market. This regulatory approval path is a significant achievement as it means that we can start the application process and potentially attain market approval significantly earlier than the initial plan of data from our ongoing phase III BALANCE clinical trial. We plan to continue the BALANCE study to further strengthen the profile of pegunigalsidase alfa,” commented Moshe Manor, Protalix’s President and Chief Executive Officer. “Approval will depend on the formal FDA review, but based on communications with the agency, Protalix remains optimistic that the FDA will approve pegunigalsidase alfa on the accelerated basis.”
