New medicine for rare diseases! Ryplazim (C-PLGD) re-applys for market: the first congenital clysolytic deficiency (C-PLGD) treatment!

Liminal BioSciences is a clinical biopharmaceutical company dedicated to developing innovative therapies for respiratory, liver and kidney diseases primarily associated with fibrosis.
recently, the company announced that it had re-submitted to the FDA, through its U.S. subsidiary Prometic Biotherapeutics, a bioprosm license application (BLA) for Ryplazim (plasminogen, fissinaseogen), a drug used to treat congenital fibranase deficiency (C-PLGD).
C-PLGD is a treatment area with significantly unsoled needs worldwide due to the lack of approved treatments.
Ryplazim has the potential to become the first FDA-approved drug to treat C-PLGD.
C-PLGD is a rare multi-system disease that has a profound impact on the health and quality of life of patients.
is a naturally occurring protein that is synthesized by the liver and circulates in the blood.
active fibrosozyme, the fibrous lysozyme, is an basic component of the fibrous system and is the main enzyme that dissolves blood clots and removes exosepin.
, fiblyzymeogen is essential for wound healing, cell migration, tissue remodeling, angiogenesy, and embryogenesy.
patients may not be born with enough fibly lysase, a condition known as congenital fibase deficiency (C-PLGD), or acute or access deficiency after trauma or illness.
C-PLGD patients accumulate fibrin growth or lesions on the surface of the mucous membranes throughout the body.
cases are first diagnosed in pediatric populations and, if left untreated, can lead to organ-damaged disease manifestations.
peer-reviewed publication reports that the prevalence of the disease globally could be 1.6 per 1 million.
15 patients with C-PLGD, including 6 children, were treated with Ryplazim for 48 weeks in a critical Phase 2/3 clinical trial for C-PLGD, according to the S fiber-soluble system (Photo: healthjade.net).
all patients treated with Ryplazim achieved at least an increase in compliance relative to the baseline of their individual fiblyzyme activity levels after 12 weeks of treatment.
, all patients who participated in the trial were actively visible lesions and fully healed within 48 weeks of the on-start treatment.
adverse events reported in clinical studies were mild, no patient deaths, serious adverse events, or adverse events that led to discontinuation of the study.
2017, Liminal BioSciences received a full response letter (CRL) from the FDA regarding Ryplazim BLA.
that the res filing of the BLA addresses the defects outlined in CRL related to certain manufacturing procedures.
the company further believes that the revised BLA represents a Category II resubmit, meaning that the FDA will complete its review and make an approval decision within six months of receiving the resubmit.
, the FDA had granted Ryplazim the orphan drug (ODD) and rare pediatric disease (PRDD) for the treatment of C-PLGD.
this means that if Ryplazim is approved, Liminal BioSciences will be eligible for a Priority Review Voucher (PRV), which can be redeemed for priority review of any subsequent new drug application and can be sold or transferred.
Moira Daniels, Director of Regulatory Affairs and Quality Assurance at Liminal BioSciences, said, "We thank all stakeholders who worked tirelessly to help us reach this milestone, including our team of professionals in production, quality control and clinical research at Liminal BioSciences, as well as the researchers, patients and families who supported the Ryplazim development program.
we are committed to providing patients with the first FDA-approved C-PLGD treatment, which will have a positive impact on patients' lives.
