Voyager Therapeutics Announces Second Quarter 2020 Financial Results and Corporate Updates

Plans to present three-year Phase 1b results of VY-AADC (NBIb-1817) in patients with Parkinson’s disease at the Movement Disorder Society (MDS) Virtual Congress 2020

Expects screening and enrollment in RESTORE-1 trial of VY-AADC (NBIb-1817) to resume during 2H 2020

Intends to submit Investigational New Drug (IND) application of VY-HTT01 for Huntington’s disease during 2H 2020

CAMBRIDGE, Mass., August 10, 2020 – Voyager Therapeutics, Inc. (NASDAQ: VYGR) today reported its second quarter 2020 financial results, program progress and corporate updates.

“We anticipate making important progress across our lead programs in the coming months, including presenting long-term clinical results from our Parkinson’s disease gene therapy program, resuming patient screening and enrollment in our RESTORE-1 trial for Parkinson’s patients, and moving our wholly-owned gene therapy for Huntington’s disease toward the clinic with an IND filing,” said Andre Turenne, President and CEO of Voyager. “We’re also excited to continue momentum on our next generation capsids, which we believe have the potential to substantially enhance and expand the therapeutic potential of AAV gene therapy to treat severe neurological diseases.”

Corporate Highlights and Program Outlook

VY-AADC (NBIb-1817) in Parkinson’s Disease

● Voyager and Neurocrine Biosciences plan to present the final three-year data on all three cohorts of the PD-1101 Phase 1b trial, as well as two-year data from the PD-1102 Phase 1 trial, at the MDS Virtual Congress 2020 being held in September. In total, these data will represent more than 60 years of patient experience following VY-AADC treatment and will include a range of patient-reported, physician-assessed, and objective endpoints.

● Voyager and Neurocrine Biosciences expect patient screening and enrollment to resume at clinical sites in the RESTORE-1 Phase 2 clinical trial during the second half of 2020. Trial sites had temporarily suspended patient screening and enrollment activity in response to the COVID-19 pandemic and the implementation of protocol amendments.

● Voyager and Neurocrine Biosciences plan to initiate the RESTORE-2 Phase 3 global registrational clinical study of VY-AADC (NBIb-1817) in Parkinson’s disease during the first half of 2021.

● Voyager and collaborators recently published a review of the evolution of novel techniques to overcome the challenges of surgical delivery of gene therapies to target brain regions, in an article titled “Data-Driven Evolution of Neurosurgical Gene Therapy Delivery in Parkinson’s Disease” in the Journal of Neurology, Neurosurgery and Psychiatry.

VY-HTT01 in Huntington’s Disease

● Huntington’s disease is a fatal genetic disease affecting approximately 40,000 people in the U.S. that results in the progressive decline of motor and cognitive functions. There are currently no approved treatments targeting the underlying cause of the disease.

● Voyager is developing VY-HTT01 as a one-time AAV-based gene therapy treatment designed to knock down expression of the HTT gene. Voyager’s approach is focused on delivering VY-HTT01 directly into the brain and targeting a reduction of the levels of mutated protein in the striatum and cortex to potentially slow the progression of both motor and cognitive symptoms.

● Voyager recently completed IND-enabling preclinical studies and is finalizing an IND application for VY-HTT01 in Huntington’s disease, which it expects to file with the U.S. Food and Drug Administration (FDA) in the second half of 2020.

● In non-human primate studies, one-time administration of VY-HTT01 resulted in robust and durable knockdown of HTT mRNA and protein, with knockdown stabilization between 6 and 12 months, and widespread distribution of VY-HTT01 vector genome across the striatum and cortex.

● VY-HTT01 treatment demonstrated robust knockdown of HTT mRNA and protein in the YAC128 and BACHD transgenic mouse models of Huntington’s disease, with significant improvements in motor function. The company plans to present preclinical data from the IND-enabling studies at a future scientific congress in the first half of 2021.

● Following clearance of the IND by the FDA, the Company expects to begin the first-in-human clinical trial of VY-HTT01 in Huntington’s disease patients.

● Voyager and collaborators recently published an article titled “Clinical Outcomes and Selection Criteria for Prodromal Huntington’s Disease Trials” in Movement Disorders. The publication analyzed the use of the normalized prognostic index (PIN) score to improve selection of pre-diagnosis Huntington’s disease patients for future clinical trials and identified outcome measures that show robust longitudinal change for measuring treatment efficacy and reducing trial size.

Novel AAV Capsid Discovery Program

● Voyager continues to progress its efforts in the discovery and engineering of novel AAV capsids with the potential to overcome the limitations of existing capsids, including greater blood-brain barrier (BBB) penetrance following IV administration. Voyager is leveraging its proprietary TRACER™ platform to facilitate the selection of AAV capsids with significantly improved BBB crossing and cell-specific transduction properties for therapeutic applications.

● Voyager has presented in vivo proof-of-concept data for capsids identified using its TRACER platform. Voyager is currently engaged in non-human primate studies to further characterize and select novel AAV capsids with improved properties and potential for therapeutic applications.

Corporate Updates

● Voyager recently appointed Maria Lopez-Bresnahan, MD, MBA, FAAN, as Senior Vice President, Translational Medicine and Clinical Development. Dr. Lopez-Bresnahan brings more than two decades of industry experience in neurological drug development, including prior clinical leadership roles at Alkermes plc, Vertex Pharmaceuticals, and Pfizer Inc.

● Following the recent conclusion of the tau and alpha-synuclein vectorized antibody collaborations with AbbVie, Voyager has regained full rights to the vectorization technology and certain novel vectorized antibodies developed as part of the collaborations.

Second Quarter 2020 Financial Results

● Collaboration Revenues: Voyager had collaboration revenue of $28.7 million for the second quarter of 2020, compared to collaboration revenue of $46.1 million for the same period of 2019. The decrease in collaboration revenue primarily reflects the termination of the Sanofi-Genzyme

Collaboration in June 2019, which resulted in the recognition of $28.7 million of previously deferred amounts. The reduction in revenue from the termination of the Sanofi Genzyme Collaboration was offset by an increase in revenue related to research services and cost reimbursements from the collaborations with Neurocrine and AbbVie in the second quarter of 2020 compared to the same period of 2019.

● Net Loss: Net loss was $8.7 million for the second quarter of 2020, compared to net income of $11.2 million for the same period of 2019.

● R&D Expenses: Research and development expenses were $29.4 million for the second quarter of 2020, compared to $28.6 million for the same period in 2019. The increase in R&D expenses was primarily related to employee-related, external and facility costs to support Voyager’s clinical and preclinical pipeline programs.

● G&A Expenses: General and administrative expenses were $8.2 million for the second quarter of 2020, compared to $8.3 million for the same period in 2019.

● Cash Position: Cash, cash equivalents and marketable debt securities as of June 30, 2020 were $229.7 million.

Financial Guidance

● Based on the Company’s current operating plan, Voyager continues to anticipate cash, cash equivalents and marketable debt securities will be between $150 million and $170 million at the end of 2020.

● Voyager expects that its cash, cash equivalents and marketable debt securities, as well as amounts expected to be received for reimbursement of development costs from Neurocrine Biosciences, will be sufficient to meet Voyager’s projected operating expenses and capital expenditure requirements into mid-2022.
