\n – Topline SAD data from healthy volunteers demonstrate safety, tolerability, and dose-proportional pharmacokinetics, supporting potentially best-in-class profile –<\/em>\n <\/p>\n

\n – MAD study initiated in patients with early Alzheimer\u2019s disease; initial tau PET imaging data expected in H2 2026 –<\/em>\n <\/p>\n

LEXINGTON, Mass., March 03, 2025 (GLOBE NEWSWIRE) — Voyager Therapeutics, Inc. (Nasdaq: VYGR), a biotechnology company dedicated to advancing neurogenetic medicines, today announced positive topline data from the Company\u2019s single ascending dose (SAD) trial of VY7523, an investigational anti-tau antibody developed to selectively inhibit the spread of pathological tau in Alzheimer\u2019s disease (AD). In the SAD trial, data on VY7523 delivered intravenously demonstrated safety, tolerability, and dose-proportional pharmacokinetics (PK). Voyager has initiated a multiple ascending dose (MAD) trial of VY7523 in patients with early AD, which is expected to generate initial tau positron emission tomography (PET) imaging data in the second half of 2026.<\/p>\n

\u201cWe continue to view tau as the most exciting target in Alzheimer\u2019s disease, which is why we are advancing two tau-targeting approaches, our anti-tau antibody and our tau silencing gene therapy,\u201d said Toby Ferguson, M.D., Ph.D., Chief Medical Officer of Voyager Therapeutics. \u201cFor the antibody approach, we believe VY7523 could be best-in-class due to the emerging PK data and previous preclinical data showing 70% reduction in tau spread, as well as its specificity for pathological tau and for a unique C-terminal epitope. We look forward to third-party data later this year and early next year, which could continue to build excitement around tau ahead of our VY7523 tau PET data.\u201d<\/p>\n

The SAD study was a randomized, double-blind, placebo-controlled trial to evaluate the safety, tolerability, and pharmacokinetics of single intravenous (IV) doses of VY7523 in 48 healthy volunteers. VY7523 was well tolerated across all six ascending dose cohorts, meeting the primary objective of the trial, with no serious adverse events (SAEs), severe adverse events, or infusion reactions reported. Secondary objectives of the trial were also met. Serum concentrations increased in a dose-proportionate manner, and the cerebrospinal fluid (CSF)-to-serum ratio was 0.3%, consistent with other monoclonal antibodies approved for the treatment of AD. Voyager expects to present additional data from the SAD study at an upcoming scientific conference.<\/p>\n

The MAD study is a randomized, double-blind, placebo-controlled trial to evaluate VY7523 in 52 patients with early AD (mild cognitive impairment due to AD or mild AD). The primary endpoint is safety and tolerability. Key secondary endpoints include the ability of VY7523 to prevent the spread of pathologic tau, as measured by tau PET imaging. Initial tau PET imaging data are expected in the second half of 2026. Additional secondary endpoints include immunogenicity and pharmacokinetic parameters.<\/p>\n

\n About VY7523<\/strong>
\n
VY7523 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\u2019s disease. VY7523 is selective for pathological tau and targets a specific C-terminal epitope of tau. In preclinical in vivo studies, the murine version of VY7523 inhibited seeding and spread of pathological tau by approximately 70%. In a single ascending dose study in healthy volunteers, data on VY7523 demonstrated safety, tolerability, and dose-proportional pharmacokinetics. Voyager is currently assessing VY7523 in a multiple ascending dose trial in patients with early Alzheimer\u2019s disease and expects initial tau PET imaging data in the second half of 2026.<\/p>\n

\n About Alzheimer\u2019s Disease<\/strong>
\n
Alzheimer\u2019s disease is a progressive neurodegenerative disease estimated to affect 7 million people in the U.S.I<\/sup> and up to 416 million people globallyii<\/sup>. 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<\/sup>. In 2023, the total cost of caring for people living with Alzheimer\u2019s and other dementias in the U.S. was estimated at $345 billioniv<\/sup>.<\/p>\n

For example, all statements Voyager makes regarding Voyager\u2019s ability to advance its tau antibody program, including expectations for Voyager\u2019s achievement of clinical development milestones for VY7523, such as clinical trial enrollment and the generation of clinical data; the commercial potential for VY7523; Voyager\u2019s expectations for the presentation of additional data from the SAD trial at a future scientific conference; and the potential for third-party clinical data to inform third-party interest in tau-targeting product candidates or Voyager\u2019s clinical development plans are forward looking.<\/p>\n

All forward-looking statements are based on estimates and assumptions by Voyager\u2019s management that, although Voyager believes such forward-looking statements to be reasonable, are inherently uncertain and subject to risks and uncertainties that may cause actual results to differ materially from those that Voyager expected.
