Pipeline
Advancing transformative medicines
for neurological diseases.
Neurologic diseases – which are estimated to impact more than 1 billion people globally – represent a significant burden on those who suffer from them, on their families and communities, and on the healthcare system.
Thanks to significant advances in human genetics and genomics, we now understand the molecular causes of many neurological diseases and know how to target them.
Our pipeline includes medicines targeting the genetics underlying multiple neurological diseases.

Patient Resources
One of Voyager’s core values is “Patients First.” This means we act with urgency and drive every decision with the knowledge that patients are waiting for us.

VY7523
anti-tau antibody for Alzheimer’s disease
Indication: Alzheimer’s disease
Modality: monoclonal antibody
Target: tau protein. Designed to target unique C-terminal epitope and block the spread of pathological tau, which is closely correlated with disease progression and cognitive decline in Alzheimer’s disease.
Key Data: At AAIC 2022, Voyager presented data demonstrating that an anti-tau antibody delivered intravenously inhibited the spread of pathological tau by >70% in a mouse seeding model. In a single ascending dose study in healthy volunteers, data on VY7523 demonstrated safety, tolerability, and dose-proportional pharmacokinetics.
Status: Multiple ascending dose trial underway.
VY1706
tau silencing gene therapy program
Indication: Alzheimer’s disease
Modality: gene therapy: novel TRACER-derived capsid with vectorized anti-tau siRNA
Target: intracellular tau
Key Data: At ADPD 2025, Voyager presented data demonstrating that a single IV administration of a tau silencing gene therapy candidate in a non-human primate (NHP) model was well-tolerated and resulted in dose-dependent reductions of tau mRNA levels (44%-73%) and tau protein levels (27%-55%) across the brain.
Status: IND anticipated in 2026
Apolipoprotein E (APOE) gene therapy program
Modality: gene therapy: novel TRACER-derived capsid with bifunctional payload designed to decrease expression of APOE in carriers of the variant APOE4, which has been strongly linked with a higher risk of developing AD, while delivering the variant APOE2, which has been associated with a lower risk of developing AD
Status: Early data presentation anticipated at an upcoming scientific meeting in 2025
