Series C in 2017
Synlogic, Inc. is a clinical-stage biopharmaceutical company based in Cambridge, Massachusetts, specializing in the development of synthetic biotic medicines aimed at treating metabolic, inflammatory, and cancer-related diseases. The company’s lead therapeutic program, SYNB1618, is currently undergoing Phase I/IIa clinical trials for the treatment of phenylketonuria, a rare genetic metabolic disorder. Additionally, Synlogic is advancing SYNB1891, an intratumoral synthetic biotic medicine in Phase I clinical trials targeting solid tumors and lymphoma. The company employs a proprietary approach that utilizes engineered probiotics, specifically Escherichia coli Nissle 1917, to create GI-restricted oral therapies that are non-colonizing and reversible, facilitating easier administration and storage. Synlogic is also exploring treatments for other conditions, including secondary hyperoxaluria, inflammatory bowel disease, and various metabolic disorders, and has established a collaboration with Ginkgo Bioworks to further its development efforts.

Solid Biosciences

Series C in 2017
Solid Biosciences Inc. is a life science company focused on developing therapies for Duchenne muscular dystrophy (DMD), a genetic muscle-wasting disease primarily affecting boys. The company's lead product candidate, SGT-001, is a gene transfer therapy currently undergoing a Phase I/II clinical trial aimed at restoring functional dystrophin protein expression in patients' muscles. In addition to SGT-001, Solid Biosciences is advancing the Anti-LTBP4 program, which involves a monoclonal antibody designed to reduce fibrosis and inflammation by targeting the LTBP4 protein. The company also develops biomarkers and sensors, as well as the Solid Suit program, which focuses on creating wearable assistive devices with functional and therapeutic benefits. Founded in 2013 and headquartered in Cambridge, Massachusetts, Solid Biosciences has established a strategic collaboration with Ultragenyx to enhance gene therapy development for DMD. With no current cure for DMD, the company aims to provide innovative solutions for a condition that affects an estimated 10,000 to 15,000 cases in the United States.
