Carbon Biosciences
Carbon Biosciences is a Waltham, Massachusetts preclinical genetic-medicine company building gene therapies on non-AAV parvovirus vectors. Founded by Longwood Fund with gene-therapy pioneers John Engelhardt and Robert Kotin, it uses a proprietary vector engine (PAVE) to design capsids from the broad parvovirus family - including human bocavirus - that carry larger genetic payloads, target specific tissues, and provoke little pre-existing immunity, opening the door to re-dosing. Its lead program targets cystic fibrosis by delivering the full-length CFTR gene to the lung, with a second vector aimed at cardiac disease.
Ring Therapeutics
Ring Therapeutics is a Cambridge, Massachusetts biotechnology company founded by Flagship Pioneering to build a new class of gene therapy delivery vectors from anelloviruses - the most abundant and diverse family of viruses that naturally and harmlessly live inside the human body. Because these commensal viruses evade the immune system, Ring's AnelloVector platform aims to solve gene therapy's biggest limitations: the inability to re-dose patients, pre-existing immunity, and narrow tissue targeting. Through its Anellogy discovery platform and AnelloBricks in-vitro manufacturing technology, Ring is engineering re-dosable, tissue-specific, scalable vectors intended to carry a wide range of therapeutic payloads.
