The company engineered probiotic bacteria, referred to as Synthetic Biotics, to perform specific therapeutic functions inside the gastrointestinal tract, such as metabolizing disease-associated compounds or producing beneficial molecules. Its development programs targeted rare metabolic disorders, including phenylketonuria (PKU) and homocystinuria. Among its investigational candidates were SYNB1934 and the earlier SYNB1618 for PKU, as well as SYNB1353 for homocystinuria. These programs were designed to address underlying metabolic imbalances by using engineered bacteria to break down or process substances that patients are unable to metabolize adequately. Synlogic was founded in 2013 and was headquartered in Cambridge, Massachusetts. The company conducted preclinical and clinical research primarily in the United States and had no commercially marketed products; its activities centered on research, development and clinical evaluation of Synthetic Biotic medicines. The company later undertook strategic changes to its pipeline and operations, and information about its ongoing corporate activities and leadership may vary from earlier public filings.AI Generated.
