About Senda Biosciences

Senda Biosciences, Inc. is committed to bringing life-changing treatments to patients by harnessing millennia of evolution to program human cells both within and to the cell. Senda’s proprietary platform is the first to leverage a universal chemical addressing code of natural nanoparticles that enable cross-kingdom intercellular communication. This platform unlocks comprehensive programming of medicines for the first time, allowing Senda to develop a new class of SendRNA™ medicines focused initially on powering new frontiers in immunology mRNA-based therapies, with future applications employing other information molecules, including siRNA, gene editors, proteins, and peptides. Headquartered in Cambridge, Massachusetts, Senda was founded by Flagship Pioneering.
