Liminal BioSciences Provides Update on Business Strategy and Focus on Small Molecule Therapeutics

Company focused on continued advancement of its small molecule therapeutics platform including development of fezagepras and evaluating strategic alternatives for its plasma-derived therapeutics business and other non-core assets.

LAVAL, Canada and CAMBRIDGE, England, Jan. 27, 2021 /PRNewswire/ - Liminal BioSciences Inc. (Nasdaq: LMNL) ("Liminal BioSciences" or the "Company"), a clinical-stage biopharmaceutical company, provided an update today regarding the Company's corporate strategy for its small molecule therapeutics and plasma-derived based therapeutics platforms. 

Following a review of its corporate business strategy, aimed at maximizing the use of capital resources, the Company has decided to re-focus its resources on its small molecule therapeutics business. It has therefore determined that its plasma-derived therapeutics business is no longer aligned with this new corporate business strategy.

As previously disclosed, the Company has been engaged in a process to find a commercialization partner for Ryplazim® (plasminogen) ("Ryplazim"), which has to date not resulted in an executable transaction.  As a consequence, and considering the ongoing cash burn associated with the plasma-derived therapeutics business, the Company announced that it has commenced a process to evaluate potential strategic alternatives for that portion of its business aimed at minimizing cash burn. These alternatives may result in a divestment, in whole or in part, of the plasma-derived therapeutics business and/or other non-core assets, or in other courses of action including but not limited to other strategic transactions or the closure of its Ryplazim related operations.

The Company believes that such change in its business strategy will allow it to become more streamlined and with a singular focus on its core research capabilities and emerging pipeline.

"We believe that this change in our  business strategy will allow us  to focus our resources on the development of our lead product candidate fezagepras and our small molecule therapeutics drug discovery program and to become a more capital efficient organization", stated Mr. Bruce Pritchard, Chief Executive Officer of Liminal BioSciences. However, as of the date hereof, the Company has not made any decisions related to any specific strategic alternatives for its plasma-derived therapeutics business and there can be no assurance of a successful outcome from these efforts, or of the form or timing of any outcome. The Company will update the market on this process when it determines that further disclosure is appropriate or necessary, including impacts on its financial results.

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.

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), has entered a Phase 1 clinical trial in Q4-2020 in the UK to evaluate multiple ascending doses of fezagepras 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, 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 clinical signs and symptoms associated with congenital plasminogen deficiency. The PDUFA target action date for Ryplazim^® 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.

Liminal BioSciences has active business operations in Canada, the United Kingdom and the United States.
