What Voyager Therapeutics, Inc. does.

We are a biotechnology company whose mission is to leverage the power of human genetics to modify the course of and ultimately cure neurological diseases. Our pipeline includes programs for Alzheimer’s disease, or AD; Friedreich’s ataxia, or FA; Parkinson’s disease, or PD; and multiple other diseases of the central nervous system, or CNS. Many of our programs are derived from our TRACER™ (Tropism Redirection of AAV by Cell-type-specific Expression of RNA) adeno-associated virus, or AAV, capsid discovery platform, which we have used to generate novel capsids, or TRACER Capsids, and identify associated receptors to potentially enable high brain penetration with genetic medicines following intravenous, or IV, dosing. Some of our programs are wholly-owned, and some are advancing with licensees and collaborators, including Alexion, AstraZeneca Rare Disease, or Alexion; Novartis Pharma AG, or Novartis; Neurocrine Biosciences, Inc., or Neurocrine; and Transition Bio, Inc., or Transition Bio.

We are advancing our own proprietary pipeline of drug candidates for neurological diseases, with a focus on AD. Our wholly-owned prioritized pipeline includes two tau targeting programs: VY1706, a tau silencing gene therapy for AD, and VY7523, an anti-tau antibody for AD. VY1706 is a gene therapy that leverages an intravenously delivered TRACER Capsid containing a vectorized small interfering RNA specifically targeting tau mRNA. In a non-human primate, or NHP, study, a single 1.3E13 vector genomes per kilogram, or vg/kg, dose of VY1706 delivered intravenously resulted in reductions in tau mRNA levels of 50% to 73% across the cerebral cortex, including in areas of the brain where tau accumulates during the progression of AD. We expect to complete a good laboratory practices, or GLP, toxicology study in the first quarter of 2026. Having had a Type C communication with the FDA in the first quarter of 2026, we anticipate the submission of an investigational new drug, or IND, application in the second quarter of 2026 and initiation of a clinical trial for the VY1706 program in the second half of 2026. 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 AD. The murine version of VY7523 reduced tau spread by approximately 70% in preclinical studies. VY7523 demonstrated an acceptable safety, tolerability, and immunogenicity profile as well as expected pharmacokinetic results in a Phase 1, single ascending dose, or SAD, clinical trial in healthy volunteers. In February 2025, we initiated a Phase 1 multiple ascending dose, or MAD, clinical trial of VY7523 in early AD patients. We expect initial tau positron emission tomography, or PET, imaging data in the second half of 2026.
