Carmine Therapeutics is pioneering a powerful new class of drugs based on engineered red blood cells extracellular vesicles (RBCEVs). Founded by Esco Ventures and Professors Harvey Lodish, Minh Le and Jiahai Shi, Carmine’s proprietary Red Cell EV Gene Therapy (REGENT™) platform has the potential to overcome the most critical shortcomings of viral-based gene therapy vectors. The company’s non-immunogenic system has already demonstrated the ability to deliver payloads over 30 kb, and to boost transgene expression through re-dosing. Carmine was awarded the 2019 Bristol-Myers Squibb’s Golden Ticket to LabCentral (Cambridge, MA) and has established a research collaboration with Takeda Pharmaceuticals in a deal worth over $900M USD. The company is well-capitalized and headquartered in Cambridge, MA, with an additional location in Singapore.
