"As announced on July 21, 2022, we met our stated milestone of obtaining clear data from the Phase 1a single-ascending dose clinical trial of fezagepras in early Q3 2022," stated Bruce Pritchard, Chief Executive Officer of Liminal BioSciences. "The decision to discontinue the development of fezagepras allows us to focus our resources on our current pipeline, including our GPR84 and OXER1 antagonist preclinical programs. We look forward to nominating our lead candidate for the Company's GPR84 antagonist program, which is expected to take place by the end of 2022."

All figures presented in this section are in Canadian dollars.

• Cash and cash equivalents were $55.8 million at June 30, 2022 while our working capital, i.e., the current assets net of current liabilities, was $35.0 million.
• Research and development expenses were $3.9 million for both of the second quarters of 2022 and 2021, with increases in professional fees and preclinical expenses of $0.2 million each, offsetting decreases in intangible assets depreciation expense of $0.4 million.
• Administration expenses were $4.6 million for the second quarter of 2022 compared to $8.6 million for the second quarter of 2021, representing a decrease of 46%. The decrease in administration expenses is primarily due to a decrease of $2.5 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 share-based payment expense of $0.6 million and in professional fees of $0.4 million.
• Net loss from continuing operations, net of taxes was $6.5 million for the second quarter of 2022 compared to $12.6 million for the second quarter of 2021. The decrease in loss was mainly due to reductions in administration expenses of $3.9 million, reflecting the reduction in insurance expense, a decrease in finance costs of $0.8 million due to the repayment of the Company's long-term debt and an increase in foreign exchange gains of $1.3 million.
• Total income (loss) from discontinued operations was income of $0.3 million for the second quarter of 2022 compared to a loss of $19.5 million in the second quarter of 2021. This decrease was mainly due to the fact that the quarter ended June 30, 2021 included the results of operations of the plasma collection activities for approximately half of the quarter, up to the time of sale, and those from the Ryplazim^® activities for the entire quarter ended June 30, 2021, where during the quarter ended June 30, 2022, our discontinued operations income or losses were mainly affected by changes in the contract and development manufacturing organization, or CDMO, lease liability and provision, remnants of the plasma-derived therapeutic segment, caused by increases in the inflation rate and variations in the discount rate. These operating losses, which decreased by $30.5 million during the second quarter of 2022 compared to the second quarter of 2021 were partially offset by a decline in gains on the sale of the discontinued operations, by $10.7 million, as we only had these transactions during the second quarter of 2021.
• Net loss was $6.2 million for the second quarter of 2022 compared to a loss of $32.1 million for the second quarter of 2021.

In July 2022, we discontinued development of fezagepras, our small molecule product candidate. The decision to discontinue the development of fezagepras was based on results from the Phase 1a single-ascending dose, or SAD, clinical trial, which indicated that fezagepras was significantly inferior compared to sodium phenylbutyrate as a nitrogen scavenger. The Phase 1a SAD clinical trial of fezagepras initiated in May 2022 was designed as a head-to-head comparison with sodium phenylbutyrate to provide us with further data to determine whether fezagepras was worth developing for one of the potential indications where nitrogen scavenging is beneficial. The recommendation to stop the development program for fezagepras was not based on safety concerns.

In August 2022, we acquired for a nominal amount, 100% of the outstanding preferred and common shares of our subsidiary, Pathogen Removal Diagnostic Technologies Inc., or PRDT, resulting in the Company now having 100% control of PRDT. PRDT owns certain prion reduction technology, which is considered a non-core asset of the Company, and is the licensee of certain prion reduction technology. As a result of the acquisition of the non-controlling interest, or NCI, in PRDT, we will no longer be presenting a balance pertaining to the NCI on our consolidated statement of financial position or in the consolidated statement of operations, from the date of the transaction.
