CAMBRIDGE, Mass., April 01, 2024 (GLOBE NEWSWIRE) -- Ring Therapeutics, a life sciences company founded by Flagship Pioneering to revolutionize programmable medicines with its commensal virome platform, today announced a pre-print publication in bioRxiv featuring the first gene delivery vector system based on a human commensal virus, the anellovirus. These data support the immense promise of Ring's AnellogyTM platform, harnessing the unique biology of commensal anelloviruses to engineer the next generation of durable and potentially redosable programmable viral vectors.
“We set out to develop an entirely new vector system based on human commensal viruses to address the many hurdles facing current genetic medicine delivery – and we've achieved that goal at remarkable speed,” said Tuyen Ong, MD, MBA, Chief Executive Officer of Ring and CEO-Partner at Flagship Pioneering.“Building on our breadth of publications showcasing anellovirus diversity, structure, tropism, and immune privilege, this new publication shows we can successfully harness the unique characteristics of anelloviruses to generate the Anellovector – the first novel viral vector in decades. This work serves as the foundation for multiple vectors coming out of our Anellogy platform and will inform upcoming IND-enabling studies, bringing Anellovectors one step closer to the clinic and patients in need.”
In the publication entitled,“A novel functional gene delivery platform based on a commensal human anellovirus demonstrates transduction in multiple tissue types,” researchers first outlined their development of a novel vector packaging system called SATURN, which packages vector payloads into the capsids of anelloviruses. This technology could enable the Anellogy platform to take advantage of the remarkable diversity of anelloviruses. In vitro function of Anellovectors in retinal pigment epithelial (RPE) cells was validated, and viral genomes were detected in the nuclei of cells by in situ hybridization. In vivo studies in mice demonstrated durable function for nine months after subretinal administration and achieved comparable expression to dose-matched AAV9 when transduced by the intracerebroventricular route of administration. Altogether, this publication strengthens the potential of Ring's Anellogy platform to generate a new class of viral vectors that could successfully evade the immune system and exhibit tissue-specific tropism, potentially overcoming some of the major challenges facing gene therapy today.
About Ring Therapeutics
Ring Therapeutics is revolutionizing the gene therapy and nucleic acid medicine space by harnessing the most abundant and diverse member of the human commensal virome, anelloviruses. The company developed the AnellogyTM platform which focuses on anelloviruses to potentially treat a broad range of diseases. Through harnessing the unique properties of these commensal viruses, the AnellogyTM platform generates diverse vectors that exhibit both tissue-specific tropism and the potential to be re-dosed. Ring Therapeutics, founded by Flagship Pioneering in 2017, aims to develop and further expand its portfolio by leveraging its platform to unlock the full potential of gene therapy and nucleic acid medicines, enabling a variety of mechanisms that successfully deliver therapeutic cargo to unreachable organs and tissues.
