Voyager Therapeutics demonstrates progress in its CNS gene therapy pipeline and tau-targeting programs for Alzheimer’s disease, positioning the company for potential value creation in the coming years.
Top Takeaways
- Voyager’s anti-tau antibody VY-7523 has entered Phase 1a trials, with topline data expected in H1 2025.
- Three gene therapy programs are on track for IND filings in 2025, including the wholly-owned SOD1 ALS program.
- The company’s TRACER platform continues to yield promising capsids for CNS gene therapy delivery.
- Strong cash position of $371 million provides runway through multiple clinical data readouts into 2027.
- Partnerships with Neurocrine, Novartis, and Alexion could generate up to $8.2 billion in long-term milestone payments.
Summary
Voyager Therapeutics reported significant progress in Q2 2024, advancing its pipeline of CNS gene therapy and antibody programs. The company dosed the first healthy volunteers in the Phase 1a trial of VY-7523, its anti-tau antibody for Alzheimer’s disease. Additionally, Voyager completed a pre-IND meeting with the FDA and initiated GLP toxicology studies for VY-9323, its SOD1 silencing gene therapy program for ALS.
“At Voyager, we are leveraging the power of human genetics to discover and develop transformative medicines that address the root cause of neurological diseases. We have made tremendous progress toward this goal in 2024, including the achievement of several important milestones in the Q2.” – Dr. Al Sandrock, CEO

Insights
Voyager’s TRACER platform continues to demonstrate robust transduction of key CNS cell types and significant liver detargeting following a single IV dose. This technology has enabled the selection of multiple development candidates in both wholly-owned and partnered gene therapy programs, potentially addressing a critical challenge in CNS drug delivery.
Market Opportunity
Voyager is targeting high unmet needs in neurological diseases, particularly Alzheimer’s disease and genetic forms of ALS. The company’s dual approach to targeting tau in Alzheimer’s disease, through both an antibody and gene therapy, could potentially address a significant market opportunity given the limitations of current treatments.
Market Commentary
The CNS gene therapy space is evolving rapidly, with multiple companies pursuing novel capsid designs for improved delivery across the blood-brain barrier. Voyager’s TRACER platform positions the company competitively in this field, with the potential to yield capsids tailored to specific diseases and cell types.
Regulatory Policy
Voyager completed a pre-IND meeting with the FDA for its SOD1 ALS program, indicating progress towards clinical development. The company is also leveraging regulatory pathways established by other approved therapies, such as in Friedreich’s ataxia, to guide its development strategies.
Industry Insights
The progress of Voyager’s programs could have implications for other players in the CNS gene therapy and Alzheimer’s disease treatment spaces. The company’s success in developing novel capsids and targeting tau could validate these approaches for the broader industry.
