GRO Biosciences (GRObio) is a biotechnology company focused on developing protein therapeutics with enhanced properties. The company leverages breakthrough technologies from computational protein design and synthetic biology to develop best-in-class protein therapeutics. GRObio is utilizing genomically recoded organisms (GROs) to expand beyond the 20 natural amino acids typically found in proteins and introduce non-standard amino acids (NSAAs) that can customize the shape and chemical properties of proteins.
GRObio's platform allows for the systematic alteration of the genetic code to incorporate NSAAs into proteins. This approach enables the company to address fundamental limitations of protein therapeutics, such as instability, immunogenicity, and delivery challenges. GRObio has developed two primary platform chemistries: DuraLogic, designed to enhance protein stability and enable flatter pharmacodynamic profiles with relaxed dosing schedules, and ProGly (programmable glycosylation), designed to enable precise regulation of the immune system's response to protein therapeutics.
In September 2023, GRObio presented preclinical data demonstrating the potential of its ProGly platform for reversing autoimmune diseases like myasthenia gravis without systemic immunosuppression and preventing immunogenic responses to protein therapeutics. The company has constructed a proprietary biofoundry with computational protein design and robotics capabilities to streamline the development of NSAAs and NSAA protein products.
GRObio was co-founded by Dr. George Church of Harvard Medical School in 2016 and is headquartered in Cambridge, MA. In November 2021, the company raised USD 25 million in Series A financing co-led by Leaps by Bayer and Redmile Group.
