Voyager Therapeutics Announces Third Quarter 2018 Financial Results and Corporate Highlights

One-time treatment with VY-AADC demonstrates durable improvements in motor function at 18 months and beyond from ongoing Phase 1b trial

Recent preclinical results for Huntington’s disease and Amyotrophic Lateral Sclerosis programs support progress towards IND filings

CAMBRIDGE, Mass., Nov. 07, 2018 (GLOBE NEWSWIRE) -- Voyager Therapeutics, Inc. (NASDAQ: VYGR), a clinical-stage gene therapy company focused on developing life-changing treatments for severe neurological diseases today reported its third quarter 2018 results, recent progress and corporate updates and will host a conference call and webcast today at 4:30 p.m. EST to discuss these results.

“We made important progress advancing our innovative pipeline in the third quarter as we presented exciting new preclinical data with our Huntington’s disease and SOD1 ALS programs and today announced durable improvements in motor function at 18 months and beyond from the ongoing Phase 1b trial with VY-AADC in patients with Parkinson’s disease,” said Andre Turenne, president and chief executive officer of Voyager Therapeutics. “We are now focused on initiating our placebo-controlled randomized Phase 2 trial with VY-AADC and further advancing our preclinical programs towards INDs in 2019.”

Recent highlights for preclinical programs:

At the Congress of the European Society of Gene and Cell Therapy (ESGCT) on October 16-19, 2018, in Lausanne, Switzerland, Voyager presented results achieving significant reductions of disease-causing gene expression in large animals following one-time delivery of VY-HTT01 for Huntington’s disease and VY-SOD102 for SOD1 ALS.

• For VY-HTT01, the use of a novel delivery paradigm targeting both the putamen and thalamus significantly reduced huntingtin, or HTT, gene expression in both deeper tissues (caudate, putamen, and thalamus) and outer layers (cortex) of the brain of adult, non-human primates. Targeting both the putamen and thalamus leverages more extensive and preserved neuronal pathways to the cortex than delivery to the putamen alone, offering the potential of a one-time treatment with VY-HTT01 to address motor, cognitive and behavioral disabilities associated with Huntington’s disease. Robust analyses including quantitative measurement in multiple tissue punches and in neurons captured by laser microdissection revealed that VY-HTT01 reduced HTT messenger RNA (mRNA) on average by 68% in the caudate, 67% in the putamen, 73% in the thalamus, and 32% in cortical neurons.
   
• For VY-SOD102 for amyotrophic lateral sclerosis (ALS) targeting SOD1, a novel delivery paradigm comprising a one-time, intraparenchymal infusion to the cervical region of the spinal cord significantly reduced SOD1 throughout the spinal cord of the mini-pig, which has a spinal cord similar in length and diameter to the human spinal cord. This novel delivery approach with VY-SOD102 reduced SOD1 mRNA in the spinal cord on average by 70% and 50% in the cervical and thoracic regions, respectively, both regions critical for respiratory function, and 82% near the site of cervical injection. In addition, VY-SOD102 reduced SOD1 mRNA by 22% in the lumbar region.

Voyager’s V-TAG™ Neuro-Navigational Surgical Device for Gene Therapy Delivery

Voyager has implemented the use of real-time, intra-operative magnetic resonance imaging (MRI) compatible devices and techniques allowing neurosurgeons more precise delivery of its gene therapy vectors. For the Phase 1b trial of VY-AADC for Parkinson’s disease, investigators used an MRI-compatible device called the ClearPoint® System from MRI Interventions, Inc. Voyager also began developing a real-time, intra-operative, MRI-compatible neuro-navigational device, the Variable Trajectory Array Guide, or V-TAG™, as a choice for neurosurgeons in addition to ClearPoint®. In July 2018, Voyager received 510(k) regulatory clearance of V-TAG™ from the Center for Devices and Radiological Health of the FDA. Beyond serving as an additional choice for neurosurgeons in the Parkinson’s disease program, V-TAG™ could also be used for Voyager’s Huntington’s disease and other programs.  

Management Update

Voyager promoted Allison Dorval to the position of chief financial officer from her previous position as vice president of finance. She remains the Company’s principal finance and accounting officer.  Ms. Dorval, a certified public accountant, joined Voyager in June 2017 and has over 20 years of experience in finance and accounting, including 10 years in various leadership roles in the life sciences industry. Prior to joining Voyager, Ms. Dorval served as vice president and controller of Juniper Pharmaceuticals, Inc., as a consultant at Danforth Advisors, and in several roles at Insulet Corporation, including as chief financial officer.  Ms. Dorval received a B.S. in Business Administration, with a concentration in Accounting, from the University of Vermont.

Third Quarter 2018 Financial Results

Voyager reported a GAAP net loss of $20.3 million, or $0.63 per share, for the third quarter ended September 30, 2018, compared to a GAAP net loss of $23.3 million, or $0.89 per share, for the same period in 2017.

Collaboration revenues of $2.1 million for the third quarter of 2018 compared to $1.1 million for the third quarter of 2017. Collaboration revenues reflect recognition of payment for research and development services provided by Voyager for various programs under the collaboration agreements with Sanofi Genzyme and AbbVie. The increase in collaboration revenues for the third quarter of 2018 reflects the recognition of revenue related to research services performed under the AbbVie collaboration agreement offset by reductions in revenue recognized under the Sanofi Genzyme collaboration that relate to research and development services as well as the adoption of certain accounting rules related to revenue recognition methodology. 

Research and development (R&D) expenses of $16.6 million for the third quarter ended September 30, 2018 compared to $19.6 million for the same period in 2017. The decrease in R&D expenses related primarily to a reduction in manufacturing expenses offset by increases in personnel and facility costs to support the advancement of VY-AADC into the Phase 2 trial and expenditures related to support Voyager’s preclinical pipeline programs.

General and administrative (G&A) expenses of $6.6 million for the third quarter 2018 compared to $4.9 million for the same period in 2017. The increase in G&A expenses was primarily due to personnel and facility costs to support the advancement of the lead and pipeline programs, platform and manufacturing capabilities.

Cash, cash equivalents, and marketable debt securities as of September 30, 2018 were $179.6 million. Based on the Company’s current operating plan, Voyager expects to end 2018 with total cash, cash equivalents and marketable debt securities above the previously guided range of $125 million to $135 million and projects that its existing cash, cash equivalents and marketable debt securities will be sufficient to fund operating expenses and capital expenditure requirements into early 2020.
