Company Summary: 

Ring Therapeutics Inc. is a privately held, early-stage biotechnology company pioneering a completely novel form of gene therapy by exploiting a family of naturally occurring commensal viruses to create the first re-dosable and targetable genetic medicines. This approach enables a powerful new class of tropic, persistent, non-integrating vectors that overcome the immunogenicity, and limited tropism of existing gene therapy vectors. Ring Therapeutics is leveraging this versatile technology to develop a broad pipeline of novel, targeted medicines for disease with high unmet medical need.

Ring Therapeutics was founded by Flagship Pioneering, focused on launching breakthrough companies based on internally conceived innovations and insights. Flagship Pioneering has created over 40 groundbreaking companies over the past fifteen years, all of which are pioneering novel and proprietary biological, industrial, and engineering approaches to solve major needs in human health and sustainability. These companies include Moderna (MRNA), Seres Therapeutics (NASDAQ:MCRB), Syros Pharmaceuticals (SYRS), Rubius Therapeutics (RUBY), Axcella Health, Evelo Biosciences (EVLO), and Indigo Agriculture.
