NEW YORK, Feb. 14, 2023 (GLOBE NEWSWIRE) -- Sio Gene Therapies Inc. (NASDAQ:SIOX) today provided financial results for its fiscal third quarter ended December 31, 2022.

"Our financial results continue to show the beneficial effects on operating expenses and cash burn resulting from the termination of the licenses to our three clinical-stage programs, the significant workforce reduction initiated last year April and successful negotiations with vendors and landlords. We are now focused on taking the steps necessary to put the Company and its three subsidiaries into the liquidation and dissolution process, including a stockholder vote expected to be held in April," said David Nassif, J.D., Chief Executive Officer of Sio Gene Therapies.

Fiscal Third Quarter Financial Summary

Research and development expenses were $1.9 million for the three months ended December 31, 2022 and $21.3 million for the three months ended December 31, 2021. The $19.4 million decrease was primarily related to decreases in:

(i) program-specific costs relating to our prior AXO-Lenti-PD and AXO-AAV-GM1 and AXO-AAV-GM2 programs, which decreased $15.5 million as we wound down our clinical-stage programs subsequent to our termination of the Oxford Biomedica and UMass agreements; and

(ii) unallocated internal costs, which decreased $3.9 million primarily due to reductions in personnel-related costs after announcing the discontinuation of our clinical-stage programs and initiating a significant reduction in workforce in April 2022.

General and administrative expenses were $2.6 million for the three months ended December 31, 2022 and $4.1 million for the three months ended December 31, 2021. The decrease of $1.5 million was primarily due to decreases of $1.0 million in stock-based compensation expense, $0.4 million of which results from prior year expense associated with Roivant Sciences Ltd. ("RSL") equity instruments held by our former Chief Executive Officer, and $0.6 million in personnel-related expenses related to the workforce reduction that commenced in April 2022.

The net loss for the fiscal third quarter ended December 31, 2022 was $4.0 million, or $0.05 per share, compared to a net loss of $25.5 million, or $0.35 per share, in the fiscal third quarter ended December 31, 2021.

As of December 31, 2022, we had $46.13 million of cash and cash equivalents. We hold no short-term or long-term debt on the balance sheet.

Fiscal Nine Months Financial Summary

Research and development expenses were $7.8 million for the nine months ended December 31, 2022 and $40.8 million for the nine months ended December 31, 2021. The $33.0 million decrease was primarily related to decreases in:

(i) program-specific costs relating to our prior AXO-Lenti-PD and AXO-AAV-GM1 and AXO-AAV-GM2 programs, which decreased $24.6 million as we wound down our clinical-stage programs subsequent to our termination of the Oxford Agreement and the UMMS Agreement; and

(ii) unallocated internal costs, which decreased $8.4 million primarily due to reductions in personnel-related costs after announcing the discontinuation of our clinical-stage programs and initiating a significant reduction in workforce in April 2022. Personnel-related costs incurred during the nine months ended December 31, 2022 included $0.7 million of severance expense. Other costs incurred during the nine months ended December 31, 2022 included $0.7 million related to the early termination of the laboratory space lease in Durham, North Carolina and $0.6 million of losses on sales of equipment and furniture related to the termination of that lease. Further, stock-based compensation expense incurred during the nine months ended December 31, 2022 benefited from the reversal of $0.4 million from prior periods resulting from the workforce reduction.

General and administrative expenses were $8.5 million for the nine months ended December 31, 2022 and $17.7 million for the nine months ended December 31, 2021. The decrease of $9.2 million was primarily due to a decrease of $8.3 million in stock-based compensation expense, $6.3 million of which results from prior year expense associated with RSL equity instruments held by our former Chief Executive Officer, and a decrease of $1.7 million in personnel-related expenses.

The net loss for the nine months ended December 31, 2022 was $15.5 million, or $0.21 per share, compared to a net loss of $58.6 million, or $0.80 per share, for the nine months ended December 31, 2021.
