About Senda Biosciences

Senda Biosciences, Inc. is uniquely positioned to transform human health by harnessing millions of years of evolution to program targeted, potent and tunable medicines. Nature has provided the codes to program human cells – both from within (mRNA) and from outside – from what surrounds them. The trillions of non-human cells in the human ecosystem have evolved natural nanoparticles that precisely shuttle biomolecules into human cells, providing the missing pieces to fully unlock programmable medicines. Senda’s proprietary platform includes the first-ever atlas of nature-derived programmable systems at the molecular level and across all kingdoms of life – accessing the entire code provided by nature required to program cells.  With this platform, Senda is developing a new class of SendRNA™ medicines.  The unique properties of these medicines create new frontiers for mRNA therapeutics and vaccines for infectious, genetic, autoimmune, and metabolic diseases and oncology indications – with further potential to transform the gene editing and protein-based therapy landscapes as well.  Based in Cambridge, MA, Senda was founded by Flagship Pioneering.
