CAMBRIDGE, Mass., Oct. 11, 2022 (GLOBE NEWSWIRE) -- Voyager Therapeutics, Inc. (Nasdaq: VYGR), a gene therapy company developing life-changing treatments and next-generation adeno-associated virus (AAV) capsids, today presented data on the discovery of a novel cell surface receptor identified as a binding receptor for a family of Voyager’s next-generation TRACER AAV capsids. This receptor is expressed in human central nervous system (CNS) and brain endothelial cells, increasing the potential for the associated capsid family to translate into humans. In addition, Voyager presented preclinical data demonstrating the potential for ultra-low dosing with a separate next-generation TRACER capsid family. These and other data were presented by Voyager at the European Society of Gene & Cell Therapy (ESGCT) 29th Annual Congress in Edinburgh, Scotland.
“Our discovery of a binding receptor for one of our capsid families, along with the data showing the receptor to be highly conserved across multiple species including humans, increases our confidence that the preclinical data on gene therapies utilizing this capsid family may translate in human clinical trials,” said Alfred Sandrock, Jr., M.D., Ph.D., Chief Executive Officer of Voyager. “In the longer term, this receptor could enable reverse engineering to further enhance our capsid discovery platform. In addition, we have begun experiments to explore whether we may be able to leverage this receptor to enable the delivery of modalities such as proteins and oligonucleotides across the blood-brain barrier – which, if successful, could constitute a new platform for CNS drug development.”
Details of Voyager’s presentations at ESGCT are as follows:
Identification of a Cell Surface Receptor Utilized by an Engineered BBB-Penetrant Capsid Family with Enhanced Brain Tropism in Non-Human Primates and Mice (Poster #P024)
Dose-Response Evaluation of 9P801, an Engineered AAV Capsid with High BBB Penetration and CNS Transduction in Non-Human Primates (Poster #P015)
Evaluation of an Early, Late, Very Late Expressed Rep in a Recombinant Baculovirus to Produce a More Potent AAV-based Gene Therapeutic in Insect Cells (Poster #P065)
About the TRACER™ AAV Capsid Discovery Platform
Voyager’s TRACER™ (Tropism Redirection of AAV by Cell-type-specific Expression of RNA) capsid discovery platform is a broadly applicable, RNA-based screening platform that enables rapid discovery of AAV capsids with robust penetration of the blood brain barrier and enhanced central nervous system (CNS) tropism in multiple species, including non-human primates (NHPs). TRACER generated capsids have demonstrated superior and widespread gene expression in the CNS compared to conventional AAV capsids as well as cell- and tissue-specific transduction, including to areas of the brain that have been traditionally difficult to reach. Separate results have demonstrated the enhanced ability of certain capsids to target cardiac muscle and to de-target the dorsal root ganglia. Voyager is expanding its library of AAV capsids optimized to deliver diverse therapeutic payloads to address a broad range of CNS and other diseases. As part of its external partnership strategy, Voyager has established multiple collaboration agreements providing access to its next-generation TRACER capsids to potentially enable its partners’ gene therapy programs to treat a variety of diseases.
About Voyager Therapeutics
Voyager Therapeutics (Nasdaq: VYGR) is leading the next generation of AAV gene therapy to unlock the potential of the modality to treat devastating diseases. Proprietary capsids born from the Company’s TRACER discovery platform are powering a rich early-stage pipeline of programs and may elevate the field to overcome the narrow therapeutic window associated with conventional gene therapy vectors across neurologic disorders and other therapeutic areas. voyagertherapeutics.com LinkedIn Twitter

Forward-Looking Statements (To Be Updated)
This press release contains forward-looking statements for the purposes of the safe harbor provisions under The Private Securities Litigation Reform Act of 1995 and other federal securities laws. The use of words such as “may,” “might,” “will,” “would,” “should,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “undoubtedly,” “project,” “intend,” “future,” “potential,” or “continue,” and other similar expressions are intended to identify forward-looking statements. For example, all statements Voyager makes regarding Voyager’s presentation of preclinical data on the discovery of a novel cell surface receptor identified as the binding receptor for a family of Voyager’s next-generation TRACER AAV capsids; Voyager’s presentation of preclinical data demonstrating the potential for ultra-low dosing with a next-generation TRACER capsid family; and Voyager’s presentation of preclinical data demonstrating that earlier expression of Replicase correlated with increased transgene packaging and higher transduction potency of assembled AAV capsids are forward looking.
All forward-looking statements are based on estimates and assumptions by Voyager’s management that, although Voyager believes such forward-looking statements to be reasonable, are inherently uncertain. All forward-looking statements are subject to risks and uncertainties that may cause actual results to differ materially from those that Voyager expected. Such risks and uncertainties include, among others, the continued development of Voyager’s technology platforms, including Voyager’s TRACER platform and Voyager’s recombinant baculovirus manufacturing platform; the ability of Voyager to initiate and conduct preclinical studies in pre-clinical animal models; the ability for Voyager’s next generation capsids to translate into humans; the ability for Voyager to attract and retain talented contractors and employees; the ability of Voyager to create and protect intellectual property; and the sufficiency of Voyager’s cash resources.
These statements are also subject to a number of material risks and uncertainties that are described in Voyager’s most recent Annual Report on Form 10-K filed with the Securities and Exchange Commission, as updated by its subsequent filings with the Securities and Exchange Commission. All information in the press release is as of the date of this press release, and any forward-looking statement speaks only as of the date on which it was made.
