Company reports second quarter 2021 financial results; extends cash runway into early 2023
“Given recent breakthroughs with our platform technologies, Voyager has transformed its pipeline to focus on advancing innovative gene therapies that leverage our proprietary next-generation AAV capsids and vectorized antibodies. In parallel, we are bolstering investment in our TRACER platform to produce additional targeted capsids with enhanced tissue- and cellular-specificity and to expand the potential of AAV-mediated genetic delivery of antibody therapies,” said
“After a rigorous and thoughtful evaluation of existing programs, we have refocused the Company on delivery technologies to power new and second-generation programs which we believe have robust target validation, an efficient path to preclinical and clinical proof of concept, and may provide meaningful therapeutic benefit,” said
Pipeline and Platform Updates
Pipeline Re-evaluation Yields High-Potential Programs
- Voyager believes its proprietary AAV capsids may enable new, best-in-class programs for spinal muscular atrophy and diseases linked to GBA1 mutations given initial data demonstrating its capsids are more reliably on-target with less risk of dose-limiting toxicities than existing AAV capsids. Second-generation and new pre-clinical programs have been initiated in the following areas:
- Huntington’s disease (second generation)
- Monogenic ALS (SOD1) (second generation)
- Spinal muscular atrophy
- Diseases linked to GBA1 mutations
- Internal development of first-generation, surgically-based gene therapy programs for the treatment of Huntington’s disease and monogenic ALS (SOD1) have been discontinued with efforts being redirected to second-generation programs.
- The Company is exploring various indications across the spectrum of GBA1 mutations, including Parkinson’s disease, Lewy body dementia, and Gaucher disease, as well as vectorized antibodies to explore undisclosed indications in neuro-oncology.
- Voyager’s current program in Friedreich’s ataxia remains partnered with Neurocrine Biosciences, Inc., and the Company’s wholly-owned vectorized antibody program focused on various tauopathies continues as planned.
TRACER AAV Capsid Discovery Platform Demonstrates Superior CNS Targeting
- The TRACER platform is designed to identify novel capsids that overcome the limitations of existing AAV capsids. The platform may be flexibly applied to discover capsids with enhanced tropism to target tissues, such as the CNS, and cardiac and skeletal muscle that may lead to treatments for a broad range of diseases.
- Initial TRACER capsid data have demonstrated robust delivery across the blood-brain barrier and widespread CNS transduction in non-human primates compared to AAV9 delivery, following intravenous (IV) administration. Capsid 9P801 displayed more than 1,000-fold higher transgene expression in the brain compared to AAV9 delivery in non-human primates.
- Capsid 9P804 displayed strong cardiac transduction and significant dorsal root ganglia detargeting, which may avoid toxicities associated with AAV9 delivery.
- Voyager is proceeding with screens of nine additional AAV capsid campaigns to further expand its capsid library and identify capsids optimized for specific applications.
Vectorized Anti-Tau Antibody Platform Demonstrates Durable CNS Expression
- Initial preclinical data have demonstrated a reduction of pathological tau with Voyager’s vectorized anti-tau antibody and durable expression in CNS.
- The Company’s vectorized antibodies may represent a new single-dose therapeutic strategy for treating various tauopathies, including progressive supranuclear palsy and frontotemporal dementia.
- Voyager has developed modular antibody vectorization cassettes, which consist of an AAV vector and a transgene encoding anti-tau monoclonal full-length antibodies. Following IV administration and transduction of target cells in the brain, the expressed antibodies are designed to be functionally reconstituted and subsequently secreted into the parenchyma, thereby enabling potential therapeutic benefit for multiple CNS diseases.
Corporate Updates and Anticipated Milestones
- In May, the Company announced the appointment of
Michael Higginsas interim chief executive officer and Glenn Pierce, M.D., Ph.D., as interim chief scientific officer. Mr. Higginshas served on Voyager’s board of directors since July 2015and has been chair of the board since June 2019. He is also the chair of the board of Pulmatrix and a board member for Genocea Biosciences, Nocion Therapeutics, Camp4 Therapeutics, and Sea Pharmaceuticals. Dr. Piercehas been a member of the board of directors since January 2017. He serves as entrepreneur-in-residence at Third Rock Ventures, where he co-founded Ambys Medicines. Dr. Piercepreviously served in a number of roles at Biogen, most recently as chief medical officer leading the hematology, cell, and gene therapies division. He is the co-author of more than 150 scientific papers and has received more than 15 patents.
Upcoming Events and Presentations
- Voyager plans to participate in the following investor events:
Wedbush Pacgrow Healthcare Conference, August 11, 2021 Canaccord Genuity Growth Conference, August 12, 2021 Wells Fargo Virtual Healthcare Conference, September 9, 2021 Morgan Stanley Global Healthcare Conference, September 14, 2021 Baird Healthcare Conference, September 15, 2021
Second Quarter 2021 Financial Results
- Collaboration Revenues: Collaboration revenue was
$1.4 millionfor the second quarter of 2021, compared to collaboration revenue of $28.7 millionfor the same period of 2020. The decrease in collaboration revenue was largely due to a reduction of revenue related to research services and cost reimbursements from the collaborations with Neurocrine and AbbVie. In February 2021, Neurocrine provided notice that, effective August 2, 2021, it was terminating its participation in the VY-AADC program for Parkinson’s disease under the collaboration agreement between the Company and Neurocrine, and that wind-down activities, including the termination by Neurocrine of its support for on-going development activities for the VY-AADC program would commence immediately. Additionally, the collaborations with AbbVie were terminated in August 2020.
- Net Loss: Net loss was
$30.1 millionfor the second quarter of 2021, compared to a net loss of $8.7 millionfor the same period of 2020.
- R&D Expenses: Research and development expenses were
$19.5 millionfor the second quarter of 2021, compared to $29.4 millionfor the same period in 2020. The decrease in R&D expenses was primarily related to lower manufacturing and clinical expenses for the VY-AADC program for Parkinson’s disease.
- G&A Expenses: General and administrative expenses were
$10.4 millionfor the second quarter of 2021, compared to $8.2 millionfor the same period in 2020. The increase in G&A expenses was primarily related to the one-time recognition of severance and stock-based compensation expense related to a former key executive, and increased facility costs.
- Cash Position: Cash, cash equivalents and marketable debt securities as of
June 30, 2021were $143.0 million.
- Based on the Company’s current operating plan and excluding any potential financing or business development activities in 2021, Voyager anticipates cash, cash equivalents, and marketable debt securities will be between
$85 millionand $90 millionat the end of 2021.
- Due in part to cost savings realized as a result of the pipeline re-evaluation, Voyager expects that its cash, cash equivalents and marketable debt securities will be sufficient to meet the Company’s planned operating expenses and capital expenditure requirements into early 2023.
About the TRACER™ AAV Capsid Discovery Platform
Voyager’s TRACER™ system is a broadly-applicable, RNA-based functional screening platform that allows for rapid in vivo evolution of AAV capsids delivered intravenously with cell-specific transduction properties in non-human primates (NHP). Initial data from the first of many libraries screened in NHPs demonstrated the proprietary capsid variants effectively penetrated the blood-brain barrier and achieved widespread biodistribution and transduction of multiple regions of the brain. Voyager is proceeding with screens of additional NHP campaigns from AAV9 and other capsid serotypes to enable the identification of novel AAV vectors optimized for specific therapeutic applications. Initial results have demonstrated the ability of certain capsids to transduce cardiac tissue and to detarget the dorsal root ganglia.
