LAVAL, QC and CAMBRIDGE, England, Jan. 19, 2022 /PRNewswire/ - Liminal BioSciences Inc. (Nasdaq: LMNL) ("Liminal BioSciences" or the "Company"), today provided an update in which it outlined key corporate and research and development priorities for 2022.

"2021 was an instrumental year in simplifying our business strategy and providing a cash runway that positions us to focus our resources on our small molecules business," stated Bruce Pritchard, Chief Executive Officer of Liminal BioSciences. "The completion of the clinical phase of our Phase 1 MAD clinical trial in our lead product candidate, fezagepras, marks an important milestone towards accelerating our R&D strategy.  We expect 2022 to be a data rich year for fezagepras as well as our GPR84 antagonist and OXER1 antagonist preclinical candidates."

Key 2021 Achievements

• Completion of the clinical phase of the Phase 1 Multi-Ascending Dose ("MAD") clinical trial in fezagepras. 
• Closing of the sale of Liminal BioSciences' plasma-derived therapeutics business to Kedrion S.p.A.
• Closing of the sale of a Rare Pediatric Disease Priority Review Voucher.
• Receipt of FDA approval for Ryplazim^® (plasminogen, human-tvmh) ("Ryplazim®"), divested as part of the sale of the plasma-derived therapeutics business.

Key Corporate and R&D Priorities for 2022
Fezagepras
During 2021, following analysis of the preliminary pharmacokinetic ("PK") data from our Phase I MAD clinical trial, Liminal announced that the Company would not be progressing the development of fezagepras for the treatment of idiopathic pulmonary fibrosis (IPF) nor hypertriglyceridemia. 

Since that announcement, the Company has completed the clinical phase of the Phase I MAD clinical trial and continues to analyse the resulting data. In addition, the Company is continuing to perform additional pre-clinical research and is preparing to perform additional early clinical research on fezagepras with a view toward determining any potential new indications. The Company expects to provide an update on the outcome of this additional research in the first half of 2022.

GPR84 Antagonists
The Company has made significant progress in the identification of high potency, small molecule antagonists of GPR84, including potential selective candidates for development from different structural classes to those GPR84 antagonists for which data has already been published.

The GPR84 receptor could be an important biological target in a number of therapeutic areas of interest. Our preclinical research indicates that expression levels of GPR84 increase significantly under inflammatory conditions. Inhibition of GPR84 appears to inhibit neutrophil and macrophage migration and reduce cytokine release. Preclinical research conducted by the Company also indicates a potential beneficial role for the antagonism of GPR84, including in the reduction of fibrosis in several diseases including kidney disease and non-alcoholic steatohepatitis (NASH).

In addition, the Company continues to work on selecting a lead drug candidate to progress to the clinic from among the Company's current lead compounds, with plans to finalize candidate selection in 2022.

OXER-1 Antagonists 
Similar to the GPR84 antagonists' program, the Company is also making progress on developing potential OXER-1 antagonist candidates.

OXER-1 is a G protein-coupled receptor (GPCR) that is highly selective for 5-oxo-eicosatetraenioc acid (5-oxo-ETE), a potent human eosinophil chemo-attractant known to be involved in eosinophilic driven diseases (EDDs).  EDDs are inflammatory illnesses, generally in respiratory, GI and skin conditions in which elevated levels of activated eosinophils are a direct cause or thought to play a pivotal role.  OXER-1 may represent a promising target in a novel pathway for the treatment of eosinophilic driven diseases (EDDs).

Although there are a number of biologics, primarily antibodies, approved for the treatment of certain EDDs, a small molecule approach to this pathway may provide a differentiated, more cost-effective therapy.

At this stage, Liminal BioSciences' expects to be able to finalise candidate selection for its OXER-1 program in 2023 to progress to the clinic.

Cash Balances
The divestment of Liminal BioSciences' plasma business and the change in domicile of the organization from Quebec to Ontario have allowed the Company to significantly streamline operations, resulting in a reduction in its ongoing costs and headcount to align with a focus on small-molecule development.  The Company's cash and cash equivalents as of September 30^th, 2021 were CAD 116.7 million. Further information in connection with the Company's cash and cash equivalent position will be provided in the Company's reporting of its 2021 fourth quarter and annual financial results together with the Company's progress on the key priorities.

During 2022, the Company will continue to review its balance sheet position and actively seek opportunities to monetize non-core assets as well as seeking ways to reduce costs relating to financial instruments and certain commitments associated with the previous operations of the organization.
