“This acquisition - explained Paolo Marcucci, Chairman of Kedrion - is an important opportunity for our future growth: it allows us immediate access to more plasma, expand our global operations to Canada and gives us an option to enrich our product portfolio with a potential therapy against a disease like the Congenital Plasminogen Deficiency (C-PLGD), if approved by the FDA.

About Ryplazim® (plasminogen)

Ryplazim® (Plasminogen) is an investigational drug based on a naturally occurring protein that is synthesized by the liver and circulates in the blood. Activated plasminogen, plasmin, is a fundamental component of the fibrinolytic system and is the main enzyme involved in the lysis of blood clots and clearance of extravasated fibrin. Plasminogen is therefore vital in wound healing, cell migration, tissue remodeling, angiogenesis and embryogenesis.

Through its US subsidiary, Prometic Biotherapeutics Inc., Liminal BioSciences resubmitted a Biologic License Application (“BLA”) in September 2020 with the U.S. Food and Drug Administration (FDA) seeking approval of Ryplazim for the treatment of clinical signs and symptoms associated with congenital plasminogen deficiency (“C-PLDG”). The FDA has provided a Prescription Drug User Fee Act (“PDUFA”) target action date of June 5, 2021.
