GreenLight Biosciences and Samsung Biologics announced the successful completion of the first commercial-scale engineering run for the companies' mRNA production partnership. Since the announcement of the strategic partnership between GreenLight Biosciences and Samsung Biologics in late 2021, technology transfer and scale-up from the lab bench to Samsung's commercial facility was completed in seven months, demonstrating platform adaptability and scalability. GreenLight's process—from drug substance and lipid nanoparticle formulation to bulk drug product—can be completed in the same facility, an important capability.

GreenLight's mRNA synthesis reaction had a titer of 12g/L at commercial scale and produced 650g of mRNA. The company's RNA platform allowed GreenLight to move from conceptualizing an mRNA vaccine to delivering released clinical trial material in less than two years. With the demonstration at Samsung, and with GreenLight's Covid booster vaccine clinical trial expected to start in 2022, GreenLight would be capable of supplying mRNA vaccine at a commercial scale.
