NEW YORK, N.Y., AND DURHAM, N.C., November 12, 2021 (GLOBE NEWSWIRE) – Sio Gene Therapies Inc. (NASDAQ: SIOX), a clinical-stage company focused on developing gene therapies to radically transform the lives of patients with neurodegenerative diseases, today provided corporate updates and financial results for its fiscal second quarter ended September 30, 2021.

"This quarter we advanced our mission of developing innovative gene therapies for patients in desperate need of new treatment options. Importantly, in October we shared the most comprehensive dataset yet from our lead program in GM1 gangliosidosis, demonstrating clear and consistent dose-dependent biomarker improvements paired with encouraging safety, neuroimaging, and clinical outcomes. These exciting results give us great confidence in the therapeutic potential of AXO-AAV-GM1, which we hope makes a difference in the lives of many patients and families living with this debilitating disease," said Pavan Cheruvu, M.D., Chief Executive Officer of Sio Gene Therapies.

Dr. Cheruvu continued, "I’m also excited by the progress this year on the development of a reliable, suspension-based manufacturing process that has generated clinical trial material for the future development of AXO-Lenti-PD. This represents an inflection point for the program that clarifies our path forward in Parkinson's disease. We are pleased to end our second fiscal quarter of 2021 with cash runway into calendar Q4 2022 and a capable team that looks forward to continued execution."

Key Highlights and Development Updates

AXO-AAV-GM1 gene therapy for GM1 gangliosidosis
Presented positive interim safety and biomarker data from ongoing Phase 1/2 clinical study at the European Society of Gene and Cell Therapy (ESGCT) Virtual Congress in October 2021:
Ten patients have received gene therapy to date without serious adverse events (SAEs) attributable to AXO-AAV-GM1
AXO-AAV-GM1 was generally well-tolerated at both low and high doses, with the majority of adverse events considered mild to moderate
Data in Type II (late-infantile to juvenile) patients demonstrated a dose-dependent improvement in key biomarkers of disease activity: β-galactosidase enzyme activity in the serum and GM1 ganglioside activity in the CSF
Serum β-galactosidase activity achieved a normal range, increasing by 12× and 17× pre-treatment levels, respectively, in both patients in the high-dose cohort at six months
All five patients in the low-dose cohort saw a 1.3-2.3× increase in the same timeframe
Levels of CSF GM1 ganglioside, the toxic substrate which accumulates in patients with GM1 gangliosidosis, were normalized in both patients in the high-dose cohort with 42% and 72% reductions, respectively, at six months
GM1 ganglioside levels were below baseline in all five low-dose patients at 12 months
No overt disease progression in six out of seven patients treated across low- and high-dose cohorts
Granted Fast Track Designation by the U.S. Food and Drug Administration (FDA)
Upcoming milestones:
1H 2022: Intend to present data update from Stage 1 of the study, including both Type I (early-infantile) and Type II patients, at future scientific conferences
1H 2022: Intend to engage with the FDA to review Stage 1 data and discuss next steps for clinical development

AXO-AAV-GM2 gene therapy for Tay-Sachs and Sandhoff diseases
Dosed first three patients in the Phase 1/2 trial investigating AXO-AAV-GM2 in Tay-Sachs and Sandhoff diseases, including one patient at the starting dose and two patients at the low dose
Granted Fast Track Designation by the U.S. FDA
Expect continued patient identification, screening, and enrollment in Stage 1 of the dose-ranging trial throughout 2021

AXO-Lenti-PD gene therapy for Parkinson’s disease
Three GMP batches have successfully completed fill and finish, achieving target titers using the updated suspension-based process
On-track to complete final testing of these batches to support certification by a Qualified Person of at least one batch for use as clinical trial material in Q4 2021
Successfully completed a scientific advice meeting with the Medicines and Healthcare Products Regulatory Agency (MHRA) in the U.K. regarding the AXO-Lenti-PD clinical development program. The MHRA provided guidance on the:
Appropriate development pathway for completion of the Phase 1 dose-ranging study
Acceptability of a comparability protocol between the prior adherent and new suspension-based manufacturing process
New device administration system to support bilateral simultaneous infusions
Expect to provide a program update in Q1 2022

Fiscal Second Quarter Financial Summary

Research and development expenses were $11.4 million for the three months ended September 30, 2021 and $5.1 million for the three months ended September 30, 2020. The $6.3 million increase was primarily related to increases in:

(i) AXO-AAV-GM1 clinical trial material manufacturing expenses for the planned enrollment of infantile patients in the high-dose cohort, as well as clinical trial expenses due to the enrollment of juvenile patients in the high-dose cohort and for the enrollment of infantile patients in the low-dose cohort;

(ii) AXO-AAV-GM2 clinical trial material manufacturing expenses for the planned enrollment of patients in the mid-to-high dose cohorts (versus the prior year period, when this program was on clinical hold), as well as clinical trial expenses associated with the ongoing enrollment of juvenile patients in the low-dose cohort and for the planned enrollment of patients in the low-to-mid dose cohorts; and

(iii) personnel-related costs primarily due to increased headcount.

These increases were partially offset by a $1.3 million decrease in AXO-Lenti-PD costs related to: (i) the delays at our partner, Oxford Biomedica (UK) Ltd. ("Oxford"), which have not only resulted in lower than expected manufacturing expenses, but have also delayed further clinical studies of AXO-Lenti-PD, and (ii) early development programs that were completed during the quarter ended December 31, 2020 and as a result, development expenses have also decreased in the current year period.

General and administrative expenses were $9.7 million for the three months ended September 30, 2021 and $4.5 million for the three months ended September 30, 2020. The increase of $5.2 million was primarily related to $5.9 million of stock-based compensation expense associated with certain Roivant Sciences Ltd. ("RSL") equity instruments that are held by our Chief Executive Officer (the "RSL Equity Instruments"), for which expensing commenced upon the liquidity event vesting condition being met upon the closing of RSL's business combination with Montes Archimedes Acquisition Corp. ("MAAC") on September 30, 2021. Going forward, these charges are expected to decline significantly on a quarterly basis. Excluding the $5.9 million of stock-based compensation expense recorded for the RSL Equity Instruments during the three months ended September 30, 2021, general and administrative expenses decreased by $0.7 million primarily related to: (i) reductions in tax and legal fees resulting primarily from the simplification of our corporate structure and the domestication of Sio Gene Therapies Inc. from Bermuda to Delaware that was completed in November 2020, and (ii) decreased rent expense due to the downsizing of our New York office footprint.

The net loss for the fiscal second quarter ended September 30, 2021 was $21.2 million, or $0.29 per share, compared to a net loss of $10.0 million, or $0.21 per share, in the fiscal second quarter ended September 30, 2020.

Fiscal First-Half Financial Summary

Research and development expenses were $19.5 million for the six months ended September 30, 2021 and $10.3 million for the six months ended September 30, 2020. The $9.2 million increase was primarily related to increases in:

(i) AXO-AAV-GM1 clinical trial material manufacturing expenses for the planned enrollment of infantile patients in the high-dose cohort, as well as clinical trial expenses due to the ongoing enrollment of juvenile patients in the high-dose cohort and for the planned enrollment of infantile patients in the low-dose cohort;

(ii) AXO-AAV-GM2 clinical trial material manufacturing expenses for the planned enrollment of patients in the mid-to-high dose cohorts (versus the prior year period, when this program was on clinical hold), as well as clinical trial expenses associated with the ongoing enrollment of juvenile patients in the low-dose cohort and for the planned enrollment of patients in the low-to-mid dose cohorts; and

(iii) personnel-related costs primarily due to increased headcount.

These increases were partially offset by a $2.4 million decrease in AXO-Lenti-PD costs related to: (i) the delays at Oxford, which have not only resulted in lower than expected manufacturing expenses, but have also delayed further clinical studies of AXO-Lenti-PD, and (ii) early development programs that were completed during the quarter ended December 31, 2020 and as a result, development expenses have also decreased in the current year period.

General and administrative expenses were $13.6 million for the six months ended September 30, 2021 and $9.1 million for the six months ended September 30, 2020. The increase of $4.5 million was primarily related to $5.9 million of stock-based compensation expense recorded for the RSL Equity Instruments during the six months ended September 30, 2021. Going forward, these charges are expected to decline significantly on a quarterly basis. Excluding the $5.9 million of stock-based compensation expense recorded for the RSL Equity Instruments during the six months ended September 30, 2021, general and administrative expenses decreased by $1.4 million primarily related to: (i) decreased rent expense due to the downsizing of our New York office footprint, and (ii) reductions in tax, legal, auditing and accounting fees resulting primarily from the simplification of our corporate structure and the domestication of Sio Gene Therapies Inc. from Bermuda to Delaware that was completed in November 2020.

The net loss for the six months ended September 30, 2021 was $33.1 million, or $0.45 per share, compared to a net loss of $18.6 million, or $0.41 per share, in the six months ended September 30, 2020. The prior year period net loss was partially offset by a gain of $2.2 million on our long-term investment in Arvelle Therapeutics B.V. ("Arvelle"). For the six months ended September 30, 2021, net cash used in operating activities was $21.9 million and net cash provided by investing activities of $4.1 million included $4.3 million of proceeds received from the sale of our long-term investment in Arvelle.

As of September 30, 2021, we had $101.7 million of cash and cash equivalents. We hold no short-term or long-term debt on the balance sheet. We estimate that our current cash and cash equivalents will sustain our operations into calendar Q4 2022, beyond the expected dates of major upcoming milestones for our AXO-AAV-GM1 gene therapy program for the treatment of GM1 gangliosidosis.
