Catherine J. Mackey, Ph.D., appointed to Board of Directors

Strong balance sheet and disciplined financial approach expected to maintain cash runway into 2024

Conference call at 4:30 p.m. ET today

CAMBRIDGE, Mass., Aug. 04, 2022 (GLOBE NEWSWIRE) -- Voyager Therapeutics, Inc. (Nasdaq: VYGR), a gene therapy and neuroscience company developing life-changing treatments and next-generation adeno-associated virus (AAV) capsids, today unveiled its prioritized therapeutic pipeline and reported second quarter 2022 financial and operating results.

“I’m excited to announce our updated portfolio strategy that prioritizes programs targeting lead indications in Alzheimer’s disease, GBA1 Parkinson’s disease, and SOD1 ALS,” said Alfred W. Sandrock, Jr., M.D., Ph.D., chief executive officer of Voyager. “We believe our highly differentiated approaches against well-validated CNS targets leveraging Voyager’s breakthrough TRACER capsids can lead to the development of new therapeutic options for these devastating diseases. In addition, we believe each of these targets has a clear path to human proof of biology that should allow us to further progress these programs in an efficient manner.”

Dr. Sandrock continued, “The recent characterization of a receptor for one of our most promising TRACER capsids, along with the preclinical cross-species transduction data we presented at ASGCT for several or our capsids, increase our confidence that our capsids may cross the blood-brain barrier in humans. On the partnership front, we believe that our Pfizer and Novartis TRACER capsid collaborations are going well with option exercise decisions upcoming in Q4 2022 and Q1 2023, respectively, and we are optimistic about the potential for similar transactions in the future.”

Prioritized Pipeline Focused on Programs with Efficient Path to Human Proof of Biology

  • Following an in-depth internal review process, Voyager has prioritized pipeline programs for its development. This review identified a compelling opportunity for each prioritized program based on the following criteria: high unmet medical need, target validation, efficient path to human proof of biology, robust preclinical pharmacology, and strong commercial potential. Voyager is evaluating partnering opportunities for its other programs.

Prioritized pipeline programs include:

  • GBA1 gene replacement to treat Parkinson’s disease patients with GBA1 mutations

    • Mutations in glucocerebrosidase 1 (GBA1), the gene encoding the lysosomal enzyme glucocerebrosidase (GCase), are the most common genetic risk factor for synucleinopathies such as Parkinson’s disease and dementia with Lewy bodies. Voyager believes restoring GCase activity may attenuate progression and potentially slow neurodegeneration. Voyager anticipates delivering GBA1 (utilizing a blood-brain barrier (BBB)-penetrant, CNS-tropic AAV capsid discovered by the TRACER (Tropism Redirection of AAV by Cell-type-specific Expression of RNA) capsid discovery platform) via intravenous (IV) delivery to enable widespread distribution to multiple affected brain regions and to avoid the need for more invasive approaches.

    • Voyager believes the measurement of the GCase substrates such as glucosylsphingosine as cerebrospinal fluid (CSF) biomarkers will facilitate efficient clinical demonstration of proof of biology.

    • At the American Society of Gene and Cell Therapy (ASGCT) 25th Annual Meeting in May, Voyager presented preclinical data demonstrating CNS target engagement and delivery of therapeutically relevant levels of the lysosomal enzyme GCase (encoded by GBA1) in a GBA loss of function mouse model, as well as sustained expression for ≥3 months following IV administration.

    • A non-human primate (NHP) capsid evaluation study is currently underway. Voyager intends to select a development candidate in the first half of 2023, to initiate a dose range finding study in NHPs in the second half of 2023, and to initiate GLP toxicology studies in 2024. Voyager anticipates an IND filing in 2025 but is actively reviewing options to accelerate the program.

  • SOD1 gene silencing to treat amyotrophic lateral sclerosis (ALS) caused by the superoxide dismutase 1 (SOD1) mutation

    • Voyager believes that a therapeutic combining a highly potent siRNA construct with a CNS-tropic, BBB-penetrant capsid discovered by Voyager’s TRACER platform allowing for IV delivery may enable broad CNS knockdown of SOD, potentially slowing the decline of functional ability. Voyager believes a Phase 1 clinical trial to demonstrate reduction in SOD1 in CSF and neurofilament light chain in plasma will provide evidence of target engagement and the attenuation of motor neuron loss, respectively.

    • At the ASGCT meeting, Voyager presented preclinical data demonstrating robust SOD1 knockdown in all levels of the spinal cord and significant improvements in motor performance, body weight, and survival in an SOD1-ALS mouse model following IV delivery of a vectorized siRNA using a mouse BBB-penetrant capsid.

    • A NHP capsid evaluation study is currently underway. The Company intends to select a development candidate in 2022, complete an NHP dose range finding study in 2023, initiate GLP toxicology studies in the first half of 2024 and file an IND in 2024.

  • Tau antibody program – Voyager is developing novel antibodies that selectively target pathological tau to address Alzheimer’s disease (AD)

    • Voyager has maintained a long-standing focus on developing novel and complementary approaches to disrupt the progression of tau pathology believed to be central to multiple neurodegenerative diseases. Collectively, its passive and vectorized anti-tau antibodies have differentiated properties, including improved targeting of specific regions of the tau protein that could offer an improved profile compared to first generation approaches.

    • Reduction of toxic tau aggregates may slow disease progression and cognitive decline in these diseases. Voyager believes its antibody targeting the C-terminus is highly differentiated from other approaches. Further, Voyager believes that following the clearance of an Investigational New Drug (IND) application, clinical assessments utilizing positron emission tomography (PET) imaging of human tau, together with measurements of plasma and CSF biomarkers have the potential to enable an efficient and accelerated demonstration of human proof of biology.

    • At the recent Alzheimer’s Association International Conference, Voyager presented data for its novel anti-tau antibodies, targeting the mid-domain and C terminus with high affinity and showing favorable biophysical characteristics and strong activity in preclinical studies. In the P301S seeding-propagation tauopathy mouse model, Voyager’s C-terminal targeting anti-tau antibody blocked the seeding/propagation of filamentous tau and demonstrated substantial reduction of induced tau pathology.

    • Humanization of the murine antibody is currently underway. Voyager intends to nominate a lead antibody development candidate in the first half of 2023, to initiate GLP toxicology studies in the second half of 2023 and to file an IND in the first half of 2024.

    • Voyager also plans to explore vectorized delivery utilizing its BBB-penetrant TRACER capsids with its anti-tau antibody.

Receptor Identified for TRACER AAV Capsid; AAV9- and AAV5-Derived TRACER Capsids Demonstrate Enhanced Brain Transduction Across NHPs and Rodents

  • Voyager announced today that it has identified the receptor for one of its most promising TRACER AAV capsids. The Company has confirmed that those capsids can bind to the human isoform of the receptor, which is expressed in brain endothelial cells and other CNS cell types. Voyager believes that characterization of this receptor-capsid interaction increases the probability that the related capsid will cross the BBB in humans. Voyager intends to share data on this finding at an upcoming scientific conference.

  • At the ASGCT meeting, Voyager presented new preclinical data on several families of novel capsids from its TRACER capsid discovery platform.

    • Voyager presented preclinical results for an AAV9-derived capsid, VCAP-102, which demonstrated 50-fold better transduction in mice and 60-fold better transduction in NHPs versus conventional AAV9 capsids following IV administration. Voyager believes demonstrating equivalent cross-species functionality is critical to increasing a capsid’s potential for translation into humans. The study also demonstrated that VCAP-102 and other TRACER capsids showed preferential tropism for glial cells in mice, which may facilitate addressing CNS indications that would benefit from non-neuronal cell transduction.

    • Voyager also presented preclinical data for an AAV5-derived capsid with enhanced CNS transduction across species. AAV5 capsids have a reduced prevalence of pre-existing neutralizing antibodies, but conventional AAV5 capsids do not allow sufficient BBB-penetration to be used for gene therapies targeting the CNS. Voyager’s AAV5-derived capsid showed 20-fold higher brain transduction and five-fold higher spinal cord transduction compared to conventional AAV9 in NHPs. Modified capsids showed improved transduction in multiple CNS regions and cell types in NHPs, together with partial de-targeting from the dorsal root ganglia.

  • Voyager continues to perform screening campaigns with its TRACER platform to identify additional proprietary AAV9- and AAV5-derived capsids and to refine already identified capsids to target or de-target multiple tissue and cell types. These capsids offer the potential to broaden the therapeutic window substantially and to enable gene therapies in a wide range of diseases based on enhanced tissue/cell tropisms that allow for lower doses and with lower off-target effects or toxicities.

    • Studies are currently underway to assess gene expression and therapeutic index at order-of-magnitude lower doses, and Voyager intends to share the results at an upcoming scientific conference.

  • Initial option exercise decision of the license agreements with Pfizer and Novartis for TRACER AAV capsids are expected by October 2022 and March 2023, respectively.

Catherine J. Mackey, Ph.D., Appointed to Board of Directors

  • In July, Voyager announced the appointment of Catherine J. Mackey, Ph.D. to its Board of Directors. Dr. Mackey is a seasoned life science executive with more than thirty years of operational experience highlighted by her tenure as Senior Vice President, Global Research & Development, for Pfizer. Dr. Mackey, who will join Voyager’s Board on August 15, has been designated as a Class I director with a term ending as of the 2025 annual meeting of Voyager shareholders. Dr. Mackey has also been appointed to the Board’s Audit Committee and Science and Technology Committee.

Second Quarter 2022 Financial Results

  • Collaboration Revenues: Voyager had collaboration revenue of $0.7 million for the second quarter of 2022, compared to $1.4 million for the same period in 2021.  The decrease in collaboration revenue was due to a reduction of Voyager’s research activities within the collaboration with Neurocrine.

  • Net Loss: Net loss was $19.1 million for the second quarter of 2022, compared to a net loss of $30.1 million for the same period of 2021. The decrease in net loss resulted primarily from a decrease in R&D expenses and G&A expenses.

  • R&D Expenses: Research and development expenses were $12.5 million for the second quarter of 2022, compared to $19.5 million for the same period in 2021. The decrease in R&D expenses was primarily a result of lower employee-related costs and lower clinical spend related to the Huntington’s disease program, as well as lower facilities costs.

  • G&A Expenses: General and administrative expenses were $7.6 million for the second quarter of 2022, compared to $10.4 million for the same period in 2021. The decrease in G&A expenses was primarily a result of lower employee-related costs, as well as lower facilities costs.

  • Cash Position: Cash, cash equivalents and marketable securities as of June 30, 2022, were $148.1 million. 

Financial Guidance

  • Voyager expects that its cash, cash equivalents, and marketable securities, together with amounts expected to be received as reimbursement for development costs under the Neurocrine collaboration, will be sufficient to meet Voyager’s planned operating expenses and capital expenditure requirements into 2024.
