About

Persephone Biosciences is a biotechnology company founded in 2017 by Stephanie Culler and Chris Calvert and based in San Diego, California. The company focuses on decoding the human gut microbiome to develop diagnostics and therapeutics in oncology and neonatal health. Its core thesis is that the composition of a patient's microbiome significantly affects how they respond to cancer immunotherapies such as checkpoint inhibitors — a hypothesis supported by a growing body of peer-reviewed clinical research. Persephone's diagnostic platform aims to predict immunotherapy response from a patient's microbiome signature prior to treatment initiation.
