About Synlogic
Synlogic is pioneering the development of a novel class of living medicines, Synthetic Biotic medicines, based on its proprietary drug development platform. Synlogic leverages the tools and principles of synthetic biology to genetically engineer probiotic microbes to perform or deliver critical functions missing or damaged due to disease. The company’s lead program, SYNB1618, targets phenylketonuria (PKU). When delivered orally, Synthetic Biotic medicines can act from the gut to compensate for the dysfunctional metabolic pathway and have a systemic effect, with the potential to significantly improve symptoms of disease for affected patients. The company is developing SYNB1891 as an immunostimulatory approach for the treatment of advanced solid tumors. In addition, the company is leveraging the broad potential of its platform to create Synthetic Biotic medicines for the treatment of other more common diseases, including inflammatory and immune disorders. Synlogic is collaborating with AbbVie to develop Synthetic Biotic-based treatments for inflammatory bowel disease (IBD). For more information, please visit www.synlogictx.com.
