We are a clinical-stage biotechnology company focused on developing and commercializing the next-generation of precision oncology medicines that inhibit DNA damage repair and cause cancer cell death through a therapeutic strategy known as synthetic lethality. Synthetic lethality represents a clinically validated approach to drug development and arises when there is a deficiency in either of two conditions that are tolerable alone in cells but lethal together. Our lead program, CYT-0851, as well as our next generation drug candidate CYT-1853, exploits a novel gain-of-function synthetically lethal relationship between overexpression of a family of DNA damaging genes called cytidine deaminases, or CDs, and functional inhibition of homologous recombination, or HR, a DNA repair pathway critical for the survival of some cancers. CYT-0851 is a novel, oral small molecule inhibitor of RAD51-mediated HR and, to our knowledge, is the only such inhibitor of RAD51-mediated HR in clinical development.
