LAVAL, QC and CAMBRIDGE, England, March 15, 2023 /PRNewswire/ - Liminal BioSciences Inc. (NASDAQ: LMNL) ("Liminal BioSciences" or the "Company"), a development-stage biopharmaceutical company focused on discovering and developing distinctive novel small molecule therapeutics for metabolic, inflammatory, and fibrotic diseases, today reported its financial results for the fourth quarter and fiscal year ended December 31, 2022.

"We begin 2023 in an exciting position, having met all our previously disclosed milestones for our GPR84 and OXER1 antagonist development programs. This includes the nomination of LMNL6511 as the candidate selected for clinical development for our GPR84 antagonist program designed to treat metabolic diseases, inflammation and/or fibrosis," stated Bruce Pritchard, Chief Executive Officer of Liminal BioSciences. "Work is also ongoing to select a lead candidate for our OXER1 antagonist program, targeting Eosinophil-driven disease. In addition, we're pleased to announce today our GPR40 agonist discovery program as the newest addition to our pipeline aiming to identify and develop a liver-safe GPR40 agonist as a possible treatment for type 2 diabetes. With this addition, we believe that our development programs have the potential to provide us with commercial opportunities in several metabolic, inflammatory and fibrotic related therapeutic areas. At the core of our strategy is our ability to advance our later-stage candidates with the intent to develop and bring first-in-class medicines to patients, supplementing this with our early-stage pipeline."

"Most importantly, we are continuing to leverage our drug discovery platform and understanding of G protein-coupled receptors to identify small molecule candidates that can accurately target GPCRs", stated Dr. Gary Bridger, Interim Chief Scientific Officer of Liminal BioSciences. "Our drug discovery platform leverages fully integrated chemistry and biology expertise supported by our broad in-vivo capabilities which has allowed us to advance our GPR84 antagonist development program. We plan to file for authorization to commence a Phase 1 clinical trial with LMNL6511 in the second half of 2023."

Key Priorities for 2023

GPR84 Antagonist Development Plan

• Subject to continued satisfactory results in ongoing clinical trial application (CTA)-enabling work, we expect to seek approval to commence a first-in-human Phase 1 clinical trial of LMNL6511 during the second half of 2023.
• On-going In-vivo experiments expected to allow us to select a lead clinical indication in the coming months.

OXER1 Antagonist Development Plan

• Development of potential OXER-1 Antagonists is progressing well, and we plan to nominate a lead candidate for further development as a potential treatment for Eosinophilic mediated diseases in H1 2023 and are aiming to commence a first-in-human clinical trial in 2024.

GPR40 Agonist Development Plan

• Development of our GPR40 agonist program aiming to identify and develop a novel liver-safe GPR40 agonist for the treatment of type 2 diabetes (T2D). Our GPR40 agonist development program is currently at the discovery stage.

As we continue work on our development programs, we are simultaneously assessing the commercial opportunities for all assets. We believe that our GPR84 antagonist, OXER1 antagonist and GPR40 agonist programs have the potential to address significant unmet medical needs. In addition to these programs, we continue to explore other development opportunities to add to our pipeline.

Recent Developments

• In November 2022, we announced some changes to our executive leadership team. Nicole Rusaw, who had been serving as interim Chief Financial Officer since March 2, 2022, was appointed as Chief Financial Officer, and Dr. Gary Bridger, member of the Board of Directors and Strategic Advisor to the Company, was named Interim Chief Scientific Officer. Dr. Bridger continues to serve as a board member of the Company.
• In December 2022, we completed the sale of a non-core real estate asset, located in Pointe-Claire, Quebec, for a purchase price of CAD 3,175,000.
• In February 2023, we completed a consolidation of all the issued and outstanding common shares of the Company on the basis of a consolidation ratio of ten (10) pre-consolidation shares for one (1) post-consolidation share  to regain compliance with the minimum bid price requirement for continued listing by achieving a closing bid price on Nasdaq Capital Market of at least $1.00 per share for a minimum of 10 consecutive trading days. 
• In February 2023, we received written notice from Nasdaq that the Company had regained compliance with Nasdaq Listing Rule 5450(a)(1) for continued listing on the Nasdaq Capital Market. 

Fourth Quarter and Year Ended December 2022 Financial Results

All figures presented in this section are in Canadian dollars.

• Cash and cash equivalents were $37.1 million at December 31, 2022 while our working capital, i.e., the current assets net of current liabilities, was $31.2 million.
• Research and development expenses were $3.5 million during the fourth quarter of 2022 compared to $4.5 million for the fourth quarter of 2021. The decrease of $1.1 million was mainly attributable to decreases in intangible assets depreciation expense, clinical trial costs and professional fees of $0.4 million, $0.5 million and $0.2 million respectively and a general reduction in operating expenses. These decreases were partially offset by an increase in pre-clinical trial costs of $0.4 million following the beginning of new pre-clinical studies that took place in 2022.
• Administration expenses were $3.9 million for the fourth quarter of 2022 compared to $5.8 million for the fourth quarter of 2021. The decrease in administration expenses was mainly attributable to a decrease of $1.5 million in expense as a result of reduced directors' and officers' insurance premiums resulting from the change in the Company's registered office from Québec to Ontario in the later part of 2021, a reduction in professional fees of $0.5 million and a reduction in share-based payments expense of $0.3 million. These decreases were partially offset by an increase in salaries and other benefits of $0.7 million.
• Net loss from continuing operations, net of taxes was $6.6 million for the fourth quarter of 2022 compared to $8.8 million for the fourth quarter of 2021. The decrease in loss was mainly driven by the reductions in administration expenses of $1.9 million, reflecting the reduction in insurance expense, a decrease in finance costs of $1.8 million due to the termination of all long-term debt and a decrease in R&D expenses of $1.1 million.
• Total income (loss) from discontinued operations was an income of $2.3 million for the fourth quarter of 2022 compared to a loss of $0.6 million in the fourth quarter of 2021. The income from the fourth quarter of 2022 comprised of the gain of $2.3 million on disposal of capital assets, following the sale of a non-core real estate asset in December 2022, formerly part of the plasma-derived therapeutics segment and previously classified as property, plant and equipment, met the criteria to be classified as held for sale during the quarter ended March 31, 2022 at a carrying amount of $0.8 million. As a result, we received $3.2 million in net proceeds from this sale.
• Net Loss was $4.2 million for the fourth quarter of 2022 compared to income of $9.3 million for the fourth quarter of 2021.
