LAVAL, QC, ROCKVILLE, MD and CAMBRIDGE, UK, Nov. 18, 2019 /PRNewswire/ - Liminal BioSciences Inc. (NASDAQ: LMNL) (TSX: LMNL)  ("Liminal BioSciences" or the "Company"), a clinical-stage biotechnology company focused on developing novel therapeutics to treat unmet needs in patients with liver, respiratory and kidney disease, announced today the presentation of two scientific posters with new preclinical data for PBI-4050 and the treatment of pulmonary arterial hypertension ("PAH") at the American Heart Association ("AHA") 2019 conference taking place on November 16-18, 2019 in Philadelphia, PA.

"Although not a current focus of the Company's research program, this new preclinical data adds to our body of knowledge of our lead compound, PBI-4050", stated Kenneth Galbraith, Chief Executive Officer of Liminal BioSciences.

Key data was presented at the conference in two poster presentations entitled:

• PBI-4050 Reduces Angio-proliferative Pulmonary Arterial Hypertension: Decreased Human Pulmonary Artery Smooth Muscle Cell Proliferation and Microvascular Endothelial Cell endoplasmic reticulum stress

About Liminal BioSciences Inc.

Liminal BioSciences is an innovative biotechnology company with a broad pipeline of small molecule therapeutics under development to treat unmet needs in patients with liver, respiratory and kidney disease, with a focus on rare or orphan diseases. Liminal BioSciences' research involves the study of several G-protein-coupled-receptors, GPR40, GPR84 and GPR120, known as free fatty acid receptors (FFAR's). These drug candidates have a novel mechanism of action as agonist ("stimulator") of GPR40 and GPR 120, and antagonist ("inhibitor") of GPR84. Our lead drug candidate, PBI-4050, is expected to enter Phase 3 clinical studies for the treatment of Alström Syndrome after further consultation and approval by the U.S. Food and Drug Administration ("FDA") and the European Medicines Agency. A second drug candidate, PBI-4547, is currently in a Phase 1 clinical study.

Liminal BioSciences has also leveraged its experience in bioseparation technologies through its wholly-owned subsidiary Prometic Bioproduction Inc. to isolate and purify biopharmaceuticals from human plasma. Our lead plasma-derived therapeutic product is Ryplazim^TM (plasminogen) for which the Company expects to file a Biologics License Application with the FDA in the first half of 2020 seeking approval to treat patients with congenital plasminogen deficiency. The Company also operates a contract development and manufacturing operation in the United Kingdom, Prometic Bioseparations Ltd. ("PBL"). Liminal BioSciences has entered into a binding share purchase agreement for the divestment of PBL, expected to close in the fourth quarter of 2019, subject to customary closing conditions.

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