| Mar 2023 | Series C | Flagship Pioneering; Alexandria Venture Investments; Invus; Kyowa Kirin; T. Rowe Price; UPMC Enterprises; Partners Investment; CJ Investment; Altitude Life Science Ventures | $87M | - | Ring Therapeutics, founded by Flagship Pioneering in 2017, is a life sciences company revolutionizing gene therapy and nucleic acid medicines using its Anellogy platform, which harnesses anelloviruses from the human commensal virome. These naturally occurring ring-shaped viruses offer unique properties like tissue-specific tropism, immune evasion, potential for re-dosing, and in vitro particle synthesis, enabling delivery to previously unreachable organs and tissues. The company has sequenced over 5,000 anelloviruses from human samples, creating the largest database to date, and published extensive preclinical studies demonstrating the platform's capabilities. On March 9, 2023, Ring Therapeutics raised $86.5 million in an oversubscribed Series C funding round, bringing total funds raised to $230 million. Investors included new participants Alexandria Venture Investments, Altitude Life Science Ventures, CJ Investment, Invus, Kyowa Kirin Co., Ltd., Partners Investment, funds advised by T. Rowe Price Associates, Inc., UPMC Enterprises, alongside founder Flagship Pioneering and all existing institutional shareholders. The proceeds will advance the Anellogy platform toward the clinic, support portfolio expansion, and fund the first AnelloVector IND filing. Ring recently appointed its first Chief Medical Officer, Christopher Wright, to lead clinical efforts. The funding validates the platform's potential to address key limitations in current gene therapy vectors, such as immunogenicity and delivery challenges. |
| Jul 2021 | Series B | Flagship Pioneering (lead); Invus; T. Rowe Price; UPMC Enterprises; Partners Investment; Altitude Life Science Ventures | $117M | $591M | Ring Therapeutics, founded by Flagship Pioneering in 2017, develops a novel gene therapy platform using anelloviruses from the human commensal virome, called the Anellogy platform, to overcome limitations of traditional vectors like adeno-associated viruses, such as immune responses and dosing challenges. The company aims to enable redosability and broader tissue targeting for applications in ophthalmology, central nervous system, cardiovascular, immuno-oncology, and other areas. On July 28, 2021, Ring raised $117 million in a Series B round led by Flagship Pioneering, with participation from Invus, Altitude Life Science Ventures, Partners Investment, UPMC Enterprises, and funds advised by T. Rowe Price. The post-money valuation was $591.37 million, with shares priced at $9.20. The funding supported expansion of the Anellogy vector platform to advance preclinical programs toward the clinic. CEO Tuyen Ong, a former Biogen executive, highlighted the platform's potential to make existing gene therapies obsolete due to its diversity and lack of immune deficiencies. Subsequently, Ring raised $86.5 million in a Series C round on March 9, 2023, from new and existing investors including Alexandria Venture Investments, CJ Investment, Kyowa Kirin, bringing total funding to $230 million by then and later $253.5 million across four rounds. The company published preclinical data on anellovirus diversity, immune evasion, tissue tropism, and in vitro synthesis, and appointed its first CMO to progress toward clinical trials. |
| Jan 2020 | Undisclosed stage | Flagship Pioneering | $50M | - | Ring Therapeutics is an early-stage biotechnology company founded by Flagship Pioneering, developing first-in-class gene therapies using a novel viral vector platform based on the human commensal virome, specifically anelloviruses, to overcome limitations of existing DNA and gene therapies such as limited tissue access, inability to redose, genomic integration risks, and poor tolerability. The company was launched around early 2020 with an initial capital commitment of $50 million solely from Flagship Pioneering to resource its founding and continued development. This appears to correspond to the company's seed or Series A stage, predating later disclosed rounds including a Series B of $117 million in July 2021 led by Flagship with co-investors like Invus, Altitude Life Science Ventures, Partners Investment, and UPMC Enterprises, and a Series C of $86.5 million in March 2023 bringing total funding to $230 million (or $253.5 million per other trackers) from investors including Alexandria Venture Investments, CJ Investment, Kyowa Kirin, and T. Rowe Price. Ring's Anellogy platform leverages the diversity of anelloviruses, which are present in all humans and enable immune evasion, tissue-specific tropism, and in vitro particle synthesis, positioning it to create next-generation programmable genetic medicines for potential applications in ophthalmology, rare/genetic diseases, central nervous system, cardiovascular conditions, immuno-oncology, and oncology. CEO Tuyen Ong, a former Biogen ophthalmology leader and Flagship CEO-Partner, has highlighted the platform's broad potential. The company has published extensive preclinical studies validating its approach but remains pre-clinical with no clinical programs launched as of the latest funding announcements. Flagship Pioneering, known for creating platforms like Moderna, continues to support Ring as a core portfolio company within its ecosystem of over 40 ventures. |
