LAVAL, QC and CAMBRIDGE, England, May 9, 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 first quarter ended March 31, 2023. 

"We remain focused on completing CTA-enabling work for our GPR84 antagonist program and progressing LMNL6511 towards initiating a Phase 1 clinical trial during the second half of 2023, with the goal of identifying an early indicator of biological activity by the end of the clinical trial," stated Bruce Pritchard, Chief Executive Officer of Liminal BioSciences. "We are also working towards analysing the data necessary to select a lead candidate for our OXER1 antagonist development program in the first half of 2023."

First Quarter Ended March 31^st 2023 Financial Results
All figures presented in this section are in Canadian dollars.

• Cash and cash equivalents were $26.9 million at March 31, 2023 while our working capital, i.e., the current assets net of current liabilities, was $25.0 million.
• Research and development expenses were $4.2 million during the first quarter of 2023 compared to $4.4 million for the first quarter of 2022. The decrease of $0.2 million in R&D expenses during the quarter ended March 31, 2023 compared to the corresponding period in 2022 was mainly attributable to a $0.4 million decrease in upfront payments relating to a royalty stream agreement, $0.4 million decrease in personnel costs, a $0.2 million decrease in professional fees, and a $0.2 million decrease in clinical trial expenses, offset by a $1.0 million increase in preclinical studies expense associated with the advancement of our GPR84 and OXER1 antagonist programs.
• Administration expenses were $3.6 million for the first quarter of 2023 compared to $4.7 million for the first quarter of 2022. The decrease of $1.1 million in administration expenses during the quarter ended March 31, 2023 compared to the corresponding period in 2022 was mainly attributable to a decrease of $0.7 million in personnel costs reflecting a decrease in our workforce and a decrease of $0.5 million in reduced directors' and officers' insurance premiums.
• Net loss from continuing operations, net of taxes was $7.6 million for the first quarter of 2023 compared to $11.2 million for the first quarter of 2022. This decrease of $3.6 million was mainly due to reductions in finance costs of $1.6 million, a decrease in administration expenses of $1.1 million and further reductions in R&D expenses of $0.2 million as we continue to streamline the business and improve operating efficiencies.
• Total income from discontinued operations Total income from discontinued operations increased by $0.1 million during the quarter ended March 31, 2023 compared to the corresponding period in 2022. This increase was mainly attributable to an indemnification adjustment expense of $0.6 million recorded against the loss on sale of discontinued operations during the first quarter of 2022 in regards a research and development tax credit claim for a former subsidiary. This increase was partially offset by a decrease in the net income from discontinued operations of $0.1 million reflecting changes in the underlying assumptions used to value the provision pertaining to a Contract Development Manufacturing Organization.
• Net Loss was $7.4 million for the first quarter of 2023 compared to income of $11.2 million for the first quarter of 2022.
