(Nasdaq: VYGR), a biotechnology company dedicated to advancing neurogenetic medicines, today reported second quarter 2024 financial and operating results. “Voyager continued to progress our pipeline in the second quarter: we initiated the single ascending dose trial of our anti-tau antibody, which has been shown to substantially reduce the spread of tau in Alzheimer’s disease in vivo models, and enrollment is on track with top-line safety and pharmacokinetic data expected in H1 2025,” said Alfred W. Sandrock, Jr., M.D., Ph.D., Chief Executive Officer of Voyager. “In parallel, we continued to advance our gene therapy pipeline, and we and our partners are on track to achieve three IND filings in 2025. Our disciplined execution, backed by a strong cash position, should enable us to achieve multiple data readouts during 2025 and 2026.” Second Quarter 2024 and Recent Highlights Dosed first participants in Phase 1a single ascending dose (SAD) trial of anti-tau antibody VY7523 (formerly VY-TAU01) for Alzheimer’s disease: This randomized, double-blind, placebo-controlled, SAD trial is evaluating the safety and pharmacokinetics of VY7523 in healthy adult volunteers. Enrollment is on track, with a total of approximately 48 patients expected to enroll across multiple cohorts.Advanced VY9323 gene therapy program for SOD1 amyotrophic lateral sclerosis (ALS): Completed pre-investigational new drug (IND) meeting with the U.S. Food and Drug Administration (FDA) and initiated Good Laboratory Practice (GLP) toxicology studies to support IND filing.Selected development candidate in GBA1 gene therapy program: The joint steering committee with collaborator Neurocrine Biosciences selected a lead development candidate for the GBA1 gene therapy program for the treatment of Parkinson’s disease and other GBA1-mediated diseases, triggering a $3 million milestone payment to Voyager. This followed the selection of a lead development candidate for the Neurocrine-partnered Friedreich’s ataxia (FA) gene therapy program in the first quarter, which resulted in a $5 million milestone payment to Voyager.Appointed Nathan Jorgensen, Ph.D., as Chief Financial Officer: Dr. Jorgensen brings to Voyager a breadth of experience spanning investment banking, public and private healthcare investing, sell-side research, and operational roles in biotech, as well as expertise in neuroscience.Presented data at the American Society of Gene & Cell Therapy (ASGCT) 27th annual meeting: Presented a broad set of translational data, including new data on second-generation TRACER™-derived AAV capsids; translatability as evidenced by cross-species and receptor data; and activity against therapeutic targets in Alzheimer’s disease and ALS. Anticipated Upcoming Milestones VY7523 anti-tau antibody for Alzheimer’s disease: Voyager expects top-line safety and pharmacokinetic data from the ongoing SAD trial in H1 2025. Voyager expects to initiate a multiple ascending dose (MAD) trial in patients with early Alzheimer’s disease in 2025. The MAD study has the potential to generate initial tau PET imaging data in the second half of 2026 to demonstrate slowing the spread of pathological tau.VY9323 SOD1 silencing gene therapy program for SOD1 ALS: Voyager expects to file an IND in mid-2025 and initiate a clinical trial in SOD1 ALS patients. The clinical trial has the potential to generate proof-of-concept data for Voyager’s novel TRACER-derived capsids and for the treatment of SOD1 ALS based on biomarkers, including cerebrospinal fluid (CSF) SOD1 and plasma neurofilament.Partnered programs: Voyager and Neurocrine Biosciences expect to file INDs for the GBA1 and Friedreich’s Ataxia gene therapy programs in 2025, as previously disclosed.

Voyager has provided in this release certain financial information that has not been prepared in accordance with GAAP, including net collaboration revenue and net research and development expenses, which exclude the impact of reimbursement by Neurocrine Biosciences (Neurocrine) and Novartis Pharma AG (Novartis) for expenses we incur in conducting preclinical development activities under our collaboration agreements. Management uses these non-GAAP measures to evaluate the Company’s operating performance in a manner that allows for meaningful period-to-period comparison and analysis of trends in its business. Management believes that such non-GAAP measures are important in comparing current results with prior period results and are useful to investors and financial analysts in assessing the Company’s operating performance. Non-GAAP financial measures are not required to be uniformly applied, are not audited and should not be considered in isolation. The non-GAAP measures give investors and financial analysts a better understanding of our net revenue and net research and development expenses without the pass-through impact of Neurocrine costs. The non-GAAP financial information presented here should be considered in conjunction with, and not as a substitute for, the financial information presented in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measures set forth below.

LEXINGTON, Mass., May 16, 2024 (GLOBE NEWSWIRE) -- Voyager Therapeutics, Inc. (Nasdaq: VYGR), a biotechnology company dedicated to advancing neurogenetic medicines, today announced that the first participants were dosed in a Phase 1a single ascending dose (SAD) trial of VY-TAU01, an investigational anti-tau antibody developed to inhibit the spread of pathological tau in Alzheimer’s disease. The objective of the randomized, double-blind, placebo-controlled, SAD trial is to evaluate the safety and pharmacokinetics of VY-TAU01 in healthy adult volunteers. The study is being conducted at a single site in the United States and is expected to enroll approximately 48 patients in multiple cohorts. Voyager anticipates that the data from the SAD trial will inform the design of a Phase 1b multiple ascending dose (MAD) trial in patients with early Alzheimer’s disease, which Voyager expects to initiate in 2025. The MAD study has the potential to generate initial tau PET imaging data in the second half of 2026, which may indicate if VY-TAU01 can slow the spread of pathological tau in the brain. “The initiation of clinical development of VY-TAU01 for the treatment of Alzheimer’s disease is an important milestone for Voyager; it demonstrates the executional abilities of our neurology drug development team, which will be central to our advancement of three wholly-owned and partnered neurology gene therapies towards IND filings next year,” said Toby Ferguson, M.D., Ph.D., Chief Medical Officer of Voyager Therapeutics. “Alzheimer’s disease remains an area with tremendous unmet patient need, despite recent advances. We are encouraged by our preclinical data demonstrating the ability of VY-TAU01 to significantly slow tau spreading, and we look forward to evaluating the therapeutic potential of VY-TAU01 in the clinic.” About VY-TAU01 VY-TAU01 is an IV-administered, recombinant, humanized IgG4 monoclonal antibody developed to inhibit the spread of pathological tau, which is closely correlated with disease progression and cognitive decline in Alzheimer’s disease. In contrast to previous N-terminal directed anti-tau antibodies that did not show efficacy in clinical studies, VY-TAU01 targets a distinct C-terminal epitope of tau and has demonstrated robust in vivo inhibition of the spread of pathological tau in a preclinical model. Additional preclinical studies have demonstrated that VY-TAU01 was well-tolerated and demonstrated a favorable pharmacokinetic pro IV administration. About Alzheimer’s Disease Alzheimer’s disease is a progressive neurodegenerative disease estimated to affect 6 million people in the U.S.i and up to 416 million people globallyii. The disease causes memory loss and may escalate to decreased independence, communication challenges, behavioral disorders such as paranoia and anxiety, and lack of physical controliii. In 2023, the total cost of caring for people living with Alzheimer’s and other dementias in the U.S. is estimated at $345 billioniv. About Voyager Therapeutics Voyager Therapeutics, Inc.
