About Liminal BioSciences Inc.

Liminal BioSciences ( is an innovative biopharmaceutical 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 FDA and EMA. A second drug candidate, PBI-4547, is currently in a Phase 1 clinical study.

Liminal BioSciences has also leveraged its lengthy 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 RyplazimTM (plasminogen) for which the Company expects to file a BLA with the US 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, deriving revenue through sales of affinity chromatography media, Prometic Bioseparations Ltd.

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