CAMBRIDGE, Mass., May 9, 2023 – Voyager Therapeutics, Inc. (Nasdaq: VYGR), a biotechnology company dedicated to breaking through barriers in gene therapy and neurology, today reported first quarter 2023 financial and operating results.

​

“Voyager started 2023 by securing $175 million upfront in a strategic collaboration with Neurocrine Biosciences for our GBA1 gene therapy program and three new gene therapy programs, followed by Novartis’s decision to exercise options to our novel capsids for two neurologic disease targets, triggering another $25 million payment. These transactions have strengthened our balance sheet while maintaining long-term value and enabled us to further advance our platform and pipeline,” said Alfred W. Sandrock, Jr., M.D., Ph.D., Chief Executive Officer of Voyager. “We also made important progress with multiple approaches to treating Alzheimer’s disease during the quarter, selecting a lead development candidate for our anti-tau antibody program and launching a new tau knockdown gene therapy program.”

Financial Guidance

Voyager is committed to maintaining a strong balance sheet that supports the advancement and growth of its platform and pipeline. Voyager continues to assess its planned cash needs both during and in future periods. As communicated previously, we expect that our cash, cash equivalents, and marketable securities, together with the $25.0 million options exercise payment received in April 2023 from Novartis, along with amounts expected to be received as reimbursement for development costs under the Neurocrine collaborations, to be sufficient to meet Voyager’s planned operating expenses and capital expenditure requirements into 2025.

​

Conference Call

About the TRACER™ AAV Capsid Discovery Platform
Voyager’s TRACER™ (Tropism Redirection of AAV by Cell-type-specific Expression of RNA) capsid discovery platform is a broadly applicable, RNA-based screening platform that enables rapid discovery of AAV capsids with robust penetration of the blood-brain barrier and enhanced central nervous system (CNS) tropism in multiple species, including non-human primates (NHPs). TRACER generated capsids have demonstrated superior and widespread gene expression in the CNS compared to conventional AAV capsids as well as cell- and tissue-specific transduction, including to areas of the brain that have been traditionally difficult to reach. Separate results have demonstrated the enhanced ability of certain capsids to target cardiac muscle and to de-target the dorsal root ganglia. Voyager is expanding its library of AAV capsids optimized to deliver diverse therapeutic payloads to address a broad range of CNS and other diseases. As part of its external partnership strategy, Voyager has established multiple collaboration agreements providing access to its next-generation TRACER capsids to potentially enable its partners’ gene therapy programs to treat a variety of diseases.

About Voyager Therapeutics

Voyager Therapeutics (Nasdaq: VYGR) is a biotechnology company dedicated to breaking through barriers in gene therapy and neurology. The potential of both disciplines has been constrained by delivery challenges; Voyager is leveraging cutting-edge expertise in capsid discovery and deep neuropharmacology capabilities to address these constraints. Voyager’s TRACER AAV capsid discovery platform has generated novel capsids with high target delivery and blood-brain barrier penetration at low doses, potentially addressing the narrow therapeutic window associated with conventional gene therapy delivery vectors. This platform is fueling alliances with Pfizer Inc., Novartis and Neurocrine Biosciences as well as multiple programs in Voyager’s own pipeline. Voyager’s pipeline includes wholly-owned and collaborative preclinical programs in Alzheimer’s disease, amyotrophic lateral sclerosis (ALS), Parkinson’s disease, and Friedreich’s Ataxia, with a focus on validated targets and biomarkers to enable a path to rapid potential proof-of-biology.

For example, all statements Voyager makes regarding Voyager’s anticipated participation in future conferences, Voyager’s ability to continue to identify and develop proprietary capsids from its TRACER capsid discovery platform with increased transgene expression, increased blood-brain barrier penetration and increased biodistribution compared to conventional AAV9 and AAV5 capsids; Voyager’s ability to utilize its novel proprietary capsids in its own product development programs; Voyager’s ability to attract parties to license its novel proprietary capsids or to participate with Voyager in research and development

collaborations utilizing its novel proprietary capsids; Voyager’s ability to advance its AAV-based gene therapy programs and tau antibody program; the preclinical development of its potential development candidates; Voyager’s ability to perform its obligations under its respective license option agreements with Pfizer and Novartis; Voyager’s entitlement to receive option exercise, milestone and royalty-based fees from Novartis and Pfizer under the respective license option agreements; Voyager’s ability to advance gene therapy product candidates under the Neurocrine collaborations into, and successfully initiate, enroll and complete, clinical trials; Voyager’s entitlement to receive milestone and royalty-based fees under the Neurocrine collaborations; Voyager’s ability to maintain its current partnerships and collaborations and to enter into new partnerships or collaborations; the continued service and suitability of recently appointed senior officers and members of the Board of Directors; Voyager’s anticipated financial results, including the receipt by Voyager of revenues or reimbursement payments from collaboration partners; and Voyager’s cash runway and Voyager’s ability to generate sufficient cash resources to enable it to continue its business and operations are forward looking.

All forward-looking statements are subject to risks and uncertainties that may cause actual results to differ materially from those that Voyager expected. Such risks and uncertainties include, among others, the continued development of Voyager’s technology platforms, including Voyager’s TRACER platform and its antibody screening technology; the ability to initiate and conduct preclinical studies in animal models; the development by third parties of capsid identification platforms that may be competitive to Voyager’s TRACER capsid discovery platform; Voyager’s ability to create and protect intellectual property rights associated with the TRACER capsid discovery platform, the capsids identified by the platform, and development candidates for Voyager’s pipeline programs; the initiation, timing, conduct and outcomes of Voyager’s preclinical studies; the possibility or the timing of the exercise of development, commercialization, license and other options under the Pfizer and Novartis license option agreements and Neurocrine collaborations; the ability of Voyager to negotiate and complete licensing or collaboration agreements with other parties on terms acceptable to Voyager and the third parties; the ability to attract and retain talented directors, employees, and contractors; and the sufficiency of cash resources to fund its operations and pursue its corporate objectives.
