Sio Gene Therapies Announces Financial Results for Third Fiscal Quarter Ended December 31, 2020

- Company had $81 million of cash and cash equivalents as of December 31, 2020, and expects to receive additional $16 million in cash in 2021 from sale of Arvelle Therapeutics shares

Cash runway expected into the second calendar quarter of 2022

NEW YORK and RESEARCH TRIANGLE PARK, N.C., Feb. 09, 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 financial results for its third fiscal quarter ended December 31, 2020.

“In recent months, Sio Gene Therapies has made important progress in advancing its patient-focused mission: harnessing the power of gene therapy to improve the lives of patients living with debilitating CNS diseases,” said Pavan Cheruvu, M.D., Chief Executive Officer of Sio Gene Therapies. “Our AAV-based gene therapies for GM1 gangliosidosis and Tay-Sachs/Sandhoff diseases are the first gene therapy programs to enter clinical trials for each indication, and we have just begun to see evidence of their therapeutic potential. For the AXO-AAV-GM1 program, we presented 6-month follow up data in GM1 gangliosidosis highlighting the potential to preserve functional outcomes, increase enzyme activity, and reduce disease burden for patients and their families. We expect to report 12-month clinical safety and efficacy from the low-dose cohort, as well as biomarker data, in the second half of 2021 while we continue to enroll patients in the high-dose cohort. We have also made significant progress with AXO-AAV-GM2, the first potentially disease-modifying gene therapy for GM2 gangliosidosis, which entered the clinic with dosing of the first infantile (Type 1) patient and will continue enrollment throughout this year.”

Dr. Cheruvu continued, “AXO-Lenti-PD represents the most advanced gene therapy in active clinical development for Parkinson’s disease, with a highly differentiated profile that aims to improve motor function across a broad spectrum of disease progression. We are working collaboratively with our partner, Oxford Biomedica, on the development of a reliable suspension-based manufacturing process to enable scale-up of production and advancement of the clinical program. Oxford Biomedica has initiated the manufacture of GMP batches using this process and we will continue to provide periodic updates on our progress.”

“Our recent rebranding as Sio Gene Therapies, establishment of a Board composed of a majority of independent directors, addition of a leading AAV scientist to our advisory board, expansion of our preclinical research and development capabilities with a new laboratory facility in North Carolina, and extended cash runway, leave us well-positioned to execute across our pipeline. Over the coming year, we intend to continue advancing treatments that have the potential to radically alter the lives of patients while we explore opportunities to augment our existing portfolio of gene therapies.”

Fiscal Third Quarter Financial Summary

For the third fiscal quarter ended December 31, 2020, research and development expenses were $6.4 million, a decrease of $1.9 million compared to the prior year quarter due to a $1.0 million nonrecurring development and regulatory milestone to UMMS achieved in the prior year period for the AXO-AAV-GM2 program. In addition, there were reduced AXO-Lenti-PD program costs of $1.0 million due to lower clinical expenses as the enrollment of Cohort 2 was completed in February 2020, as well as lower manufacturing expenses due to delays in the development of a suspension-based manufacturing process by our partner, Oxford Biomedica.

General and administrative expenses for the third fiscal quarter ended December 31, 2020 were $4.2 million, a decrease of $1.2 million compared to the prior year quarter, primarily due to a reduction in stock-based compensation expense attributable to reduced headcount and lower grant date fair values per share for equity awards, as well as reduced outside legal costs.

The net loss for the third fiscal quarter ended December 31, 2020 was $10.5 million, or $0.20 per share, compared to a net loss of $14.0 million, or $0.62 per share, in the prior year quarter.

Nine-Months Financial Summary

For the nine months ended December 31, 2020, research and development expenses were $16.7 million, a decrease of $19.5 million compared to the nine months ended December 31, 2019. The current period decrease was primarily related to $14.0 million in certain nonrecurring development and regulatory milestones achieved in the prior year period for the AXO-Lenti-PD and AXO-AAV-GM2 programs. As well, there were reduced program-specific research and development costs of $3.7 million due to (i) lower AXO-Lenti-PD clinical expenses as the enrollment of Cohort 2 was completed in February 2020, as well as lower manufacturing expenses due to the delays at Oxford and (ii) reduced clinical and manufacturing expenses while awaiting FDA clearance of the IND for the AXO-AAV-GM2 program.

General and administrative expenses for the nine months ended December 31, 2020 were $13.3 million, a decrease of $3.6 million compared to the nine months ended December 31, 2019, primarily related to reductions in (i) personnel costs (including severance) of $1.2 million and stock-based compensation expense of $1.0 million attributable to reduced headcount and lower grant date fair values per share for equity awards, (ii) outside legal costs of $0.7 million, and (iii) pharmaceutical market research expenses of $0.6 million.

The net loss for the nine months ended December 31, 2020 was $29.1 million, or $0.61 per share, compared to a net loss of $56.0 million, or $2.46 per share, in the nine months ended December 31, 2019. Net cash used in operating activities was $36.3 million for the nine months ended December 31, 2020.

As of December 31, 2020, we had $81.0 million of cash and cash equivalents. We hold no short-term or long-term debt on the balance sheet. We expect the cash and cash equivalents to sustain our operations into the second calendar quarter of 2022.
