Codiak Biosciences Inc. scored its first partnership, putting ink to a contract with Dublin-based Jazz Pharmaceuticals plc to develop exosome-based therapeutics for cancer, "an area of biology that has really exploded in the last few years, probably starting with the realization that exosomes represent a fundamental communication system that cells use all the time, particularly in places like the tumor microenvironment," Codiak CEO Douglas Williams said. "There's a great understanding now that there's a lot of cross talk taking place between the tumor cells, the immune cells and the microenvironment, using exosomes as the vehicle."
