Persephone Biosciences uses gut microbiome profiling and synthetic biology to develop cancer immunotherapy response predictors and novel therapeutics; founded 2017 in San Diego; received BARDA funding for microbiome-based diagnostics;
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.
Saluda Medical is the pioneer of closed-loop spinal cord stimulation (SCS); FDA-approved Evoke SCS system with real-time neural feedback; raised $100M in Jan 2025; received FDA clearance for automated EVA programming platform.
