LAVAL, QC, and CAMBRIDGE, England, March 17, 2022 /CNW Telbec/ - Liminal BioSciences Inc. (Nasdaq: LMNL) ("Liminal BioSciences" or the "Company"), today reported its financial results for the fourth quarter and year ended December 31, 2021.

"The leadership team and I are pleased to have successfully delivered on our objective of simplifying our business structure over the past 12 months as part of our evolution in becoming a streamlined small molecules business," stated Bruce Pritchard, Chief Executive Officer of Liminal BioSciences. "Today, Liminal BioSciences is a streamlined and debt-free Company, we believe that our pipeline is positioned to deliver multiple anticipated value inflection points throughout 2022 with unencumbered intellectual property and a data-driven clinical development plan. We are also pleased to announce the appointment of Nicole Rusaw, as our Interim Chief Financial Officer effective as of March 2, 2022. Nicole brings with her over 20 years of financial management experience in the biotech and pharmaceutical industry, and 17 years of experience in publicly traded companies. Nicole's skills and experience complement those of the existing team and will add additional management bandwidth to allow us to continue delivering on our business objectives." Mr. Pritchard added, "We believe we have a solid foundation for growth and our full attention is on delivering on our upcoming clinical trial for our lead candidate fezagepras, as well as progressing toward the selection of our lead GPR84 antagonist and OXER1 antagonist preclinical product candidates."

Key Corporate and R&D Priorities

• The Company has completed its Phase 1 MAD clinical trial, and analysis of the metabolite data provided evidence to support the hypothesis that fezagepras has nitrogen scavenging properties. The Company intends on initiating further research, including a Phase 1a single ascending dose ("SAD") clinical trial in healthy volunteers, to assess the relative effectiveness of fezagepras as a nitrogen scavenger in a head-to-head comparison with sodium phenylbutyrate, an established nitrogen scavenging drug, to obtain comparative data for the further development of fezagepras. The Company plans to initiate the Phase 1a, randomized, open label, cross over, clinical trial which will aim to evaluate the safety, tolerability, and pharmacokinetics of SAD of fezagepras compared to sodium phenylbutyrate in healthy subjects in the second quarter of 2022, subject to the receipt
  of required approvals.
• The Company continues to work on selecting a lead drug candidate for its GPR84 antagonist program to progress to the clinic from among the Company's current lead compounds, with plans to finalize lead product candidate selection in 2022.
• Similarly, the Company expects to be able to finalize lead candidate selection in 2023 for its OXER-1 program to progress to the clinic.
• 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.

Fourth Quarter and Full Year 2021 Financial Results

The Company has presented the current and comparative period results of its former plasma-derived therapeutics segment as discontinued operations as a result of its divestment of this business. All figures presented in this section are in Canadian dollars unless otherwise specified.

• Cash was $108.5 million at December 31, 2021 while the Company's working capital, i.e., the current assets net of current liabilities, was $96.1 million at December 31, 2021. Subsequent to year end, the Company repaid its  secured  loan for an aggregate amount of $39.1 million, thereby terminating the consolidated loan agreement with Structure Alpha LP ("SALP"), releasing the security granted in favor of SALP over the Company's assets, including intellectual property; cancelling the warrants issued pursuant to the consolidated loan agreement and terminating the royalty stream agreement entered into between the Company and SALP.
• Revenues from continuing operations were $643K for the year ended December 31, 2021, compared to $724K for the year ended December 31, 2020.
• Research and development ("R&D") expenses from continuing operations were $4.5 million for the fourth quarter of 2021 compared to $3.0 million for the fourth quarter of 2020, and $18.3 million for the year ended December 31, 2021, compared to $14.2 million for the year ended December 31, 2020. The increase in R&D expenses is mainly due to increases in intangible amortization expenses, as well as a decrease in government grants, in addition to increases in clinical and preclinical expenses, and consulting fees on a year-over-year basis. These increases were partially offset by a decrease in share-based compensation expenses year-over-year.
• Administration expenses from continuing operations were $5.8 million for the fourth quarter of 2021 compared to $7.5 million for the fourth quarter of 2020, and $31.9 million for the year ended December 31, 2021, compared to $32.6 million for the year ended December 31, 2020. The decrease in administration expenses is primarily due to reduced directors' and officers' insurance premiums resulting from the change in the Company's registered office from Quebec to Ontario, as well as the fact that the comparative period expense contained a one-time charge of approximately $2.2 million relating to additional warrants issued pursuant to an amended Securities Purchase Agreement dated November 2020 with no equivalent cost in 2021. The decrease in administration expenses during fiscal 2021 was partially offset by increases in share-based payment expenses as well as reduction in government grants.
• Finance costs were $1.6 million for both the fourth quarter of 2021 and 2020, and were $6.3 million for the year ended December 31, 2021, compared to $2.9 million for the year ended December 31, 2020. The $3.4 million increase in finance costs year over year reflects the increase in our level of indebtedness following the issuance of the secured convertible debentures ("SCD") in July 2020, which remained outstanding until the SCD were converted into our common shares in October 2021, and the issuance of additional long-term debt to SALP in September 2020.
• Net loss from continuing operations, net of taxes was $8.8 million for the fourth quarter of 2021 compared to $12.6 million for the fourth quarter of 2020, and $45.1 million for the year ended December 31, 2021, compared to $49.0 million for the year ended December 31, 2020. The decrease in loss was mainly due to the reduction in administration expenses and the increase in the gain on the change in fair value of the warrant liability. The decrease in net loss from continuing operations, net of taxes, was partially offset by the previously discussed increase in research and development expenses and a decrease in impairment losses.
• Gain/loss on sale of subsidiaries was a loss of $0.1 million for the fourth quarter of 2021 compared to a gain of $3.4 million in the fourth quarter of 2020, and a gain of $140.4 million for the year ended December 31, 2021 compared to a gain of $3.4 million for the year ended December 31, 2020. The gain on sale of subsidiaries during fiscal year 2021 is a result of the sale of the Pediatric Disease Priority Review Voucher ("PRV") for gross proceeds of $132.9 million (USD 105 million) and the proceeds received on the sale of our subsidiary Prometic Bioproduction Inc. ("PBP") in July 2021 as well as those received from the sale of our Prometic Biotherapeutics Inc. ("PBT") subsidiary in October 2021. During the fourth quarter of fiscal 2020, the Company finalized the post-closing conditions of the Prometic Bioseparations Ltd. ("PBL") sale, resulting in a gain of $3.4 million in the comparative period.
• Net Loss from discontinued operations was a loss of $0.4 million for the fourth quarter of 2021 compared to a loss of $30.8 million in the fourth quarter of 2020, a decrease of $30.3 million. This decrease was mainly due to the recognition of an impairment of $19.7 million during the fourth quarter of 2020 and since there were only minor expenses incurred in the fourth quarter of 2021 until PBT was sold on October 15, 2021 compared to having the full operations of the plasma-derived therapeutics segment in the comparative period. The net loss from discontinued operations was $83.1 million for the year ended December 31, 2021, compared to a loss of $73.1 million for the year ended December 31, 2020. The increase in net loss was due to payments made by PBT to PBP, when PBP was under the ownership of Kedrion S.p.A., of $45.8 million for R&D services and the recording of an onerous contract of $21.9 million as a result of the divestiture of the plasma-derived therapeutic segment. This increase was partially offset by a reduction in impairment losses and since the discontinued operations results include the results for PBP and PBT until the date of their sale.
• Net income/loss was a loss of $9.3 million for the fourth quarter of 2021 compared to a loss of $40.0 million for the fourth quarter of 2020, and net income of $12.2 million for the year ended December 31, 2021 compared to a net loss of $118.8 million for the year ended December 31, 2020, the decrease in net loss driven by the discontinued operations.
