LAVAL, QC and CAMBRIDGE, England , Dec. 7, 2020 /CNW Telbec/ - Liminal BioSciences Inc. (Nasdaq: LMNL) ("Liminal BioSciences" or the "Company"), a clinical-stage biopharmaceutical company, today announced the presentation of two scientific posters with individual case report data highlighting potential activity of intravenous Ryplazim® (plasminogen) on infertility and acute airway obstruction in patients with congenital plasminogen deficiency ("C-PLGD"). Results were presented during the 62 nd American Society of Hematology Annual Meeting and Exposition.
Two posters were presented that highlighted individual case histories of patients with C-PLGD treated with the investigational intravenous Ryplazim® (plasminogen) in compassionate use and expanded access cases. The first poster was a case of a previously infertile female patient having a successful pregnancy. The second poster reported 4 cases of acute respiratory distress with successful resolution of airway obstruction.
"This data related to treatment with investigational plasminogen replacement shows promise as a potential therapy to target the many life-altering and potentially life-threatening systemic manifestations of congenital plasminogen deficiency through intravenous plasminogen (human) replacement therapy", stated Bruce Pritchard , Chief Executive Officer. "These data highlight the potential impact for the treatment of congenital plasminogen deficiency in two areas that can present significant challenges for patients caused by plasminogen deficiency.
Both poster presentations were also published in the November supplemental issue of the peer-reviewed journal Blood along with a Comprehensive Case Review entitled 'Painting the Clinical Picture Of Congenital Plasminogen Deficiency (C-PLGD) through A Comprehensive Case Study Review'.
The poster presentations are entitled:
- Successful Pregnancy in A Patient with Infertility Due To Congenital Plasminogen Deficiency Treated With Intravenous Plasminogen (Human) Replacement Therapy
- Acute Airway Obstruction in 4 Pediatric Patients with Congenital Plasminogen Deficiency (C-PLGD) Treated with Intravenous Plasminogen (Human) Replacement Therapy Under an Expanded Access Protocol
This is the only reported case of a patient with C-PLGD and documented infertility who was being treated with investigational intravenous plasminogen (human) replacement therapy in the Phase 2/3 clinical trial and subsequently became pregnant. Treatment with plasminogen was continued throughout the pregnancy following agreement with both the national regulatory and study ethical review. The pregnancy was successful, and the patient delivered a healthy child.
In the case series of acute airway obstruction, Dr. Charles Nakar of Indiana Hemophilia And Thrombosis Center who presented the poster, concluded that "these cases demonstrate the potential for IV plasminogen concentrate replacement therapy to provide rapid regression and prevent respiratory failure and potential serious sequalae in C-PLGD patients with airway involvement due to fibrinous lesions."

About Liminal BioSciences Inc.
Liminal BioSciences is a clinical-stage biopharmaceutical company focused on discovering, developing and commercializing novel treatments for patients suffering from diseases of high unmet medical need, primarily related to fibrosis, including respiratory, liver and kidney diseases. Liminal BioSciences has a deep understanding of certain biological targets and pathways that have been implicated in the fibrotic process, including fatty acid receptors such as FFAR1, G-protein-coupled receptor 84 (GPR84), and peroxisome proliferator-activated receptors (PPARs). Our lead small molecule product candidate, fezagepras (PBI-4050), is expected to enter a Phase 1 clinical trial in Q4-2020 in the UK to evaluate multiple ascending doses in normal healthy volunteers, at daily dose exposures higher than those evaluated in our previously completed Phase 2 clinical trials. Fezagepras is expected to be further evaluated in a global Phase 2b clinical trial in patients with idiopathic pulmonary fibrosis (IPF) anticipated to be initiated in H2-2021. In addition, we expect to initiate a Phase 1b /2a clinical trial of fezagepras, likely in the US, for patients with high triglyceride levels (hypertriglyceridemia) in H2-2021.
Fezagepras has previously been granted Orphan Drug Designation by the FDA and the European Medical Agency (EMA) for the treatment of IPF. The treatment has also received a Promising Innovative Medicines (PIM) designation by the Medicines and Healthcare products Regulatory Agency (MHRA) for IPF.
Liminal BioSciences has also leveraged its experience in bioseparation technologies through its subsidiary Prometic Bioproduction Inc. to isolate and purify biopharmaceuticals from human plasma. Liminal BioSciences' lead plasma-derived product candidate is Ryplazim ® (plasminogen) ("Ryplazim ® "), for which the Company, through its US subsidiary, Prometic Biotherapeutics Inc., resubmitted a BLA in September 2020 with the FDA seeking approval to treat patients with congenital plasminogen deficiency. The PDUFA target action date for this BLA filing is June 5, 2021 . Ryplazim ® has previously been granted Orphan Drug and Rare Pediatric Disease Designations by the FDA for the treatment of congenital plasminogen deficiency.
Prometic Plasma Resources, a subsidiary of Liminal BioSciences, has joined the CoVIg-19 Plasma Alliance to contribute to the acceleration of the development of a potential new therapy for COVID-19. Liminal BioSciences' Canadian plasma collection center located in Winnipeg, Manitoba is licensed by the FDA and Health Canada, and is certified by the European Union and the Plasma Protein Therapeutics Association. Liminal BioSciences' American plasma collection center located in Amherst, New York is licensed by the State of New York and its BLA submission is currently under review by the FDA.
