About AnaptysBio

AnaptysBio is a privately-held company focused on the generation of antibody therapeutics and is the leader in the use of somatic hypermutation (SHM) for antibody discovery and optimization. We are developing a pipeline of novel therapeutic antibody candidates, including differentiated programs in cancer immunotherapy, inflammation, fibrosis, muscle wasting disorders and antibody-drug conjugate applications. AnaptysBio's proprietary SHM-XEL platform, which couples fully human antibody libraries with in vitro somatic hypermutation in mammalian cells to generate high affinity antibodies, replicates key features of the human immune system and overcomes limitations of prior antibody technologies. By harnessing the natural mechanism of antibody maturation under controlled conditions, SHM-XEL allows for the selection of optimal antibody properties such as high affinity, stability, function, cross-reactivity, epitope diversity and manufacturability. The Company has previously announced partnerships with Merck, Roche, Novartis, Celgene, Gilead, DARPA and DTRA. Major investors in AnaptysBio include Alloy Ventures, Avalon Ventures, Frazier Healthcare Ventures and Novo A/S. For more information, visit
