Codexis, Inc. (Nasdaq:CDXS) today announced it has been awarded the annual Presidential Green Chemistry Challenge Award from the U.S. Environmental Protection Agency (EPA) for the development of an efficient biocatalytic process to manufacture simvastatin, a leading drug for treating high cholesterol. This marks the third time in seven years that Codexis has been honored with this award; Codexis was a recipient in 2006 and 2010. Simvastatin is the most prescribed statin in the U.S., with 94.1 million prescriptions in 2010 according to IMS Health. Traditionally, synthesis of simvastatin has required an inefficient, multistep chemical process that involves significant quantities of hazardous reagents. In collaboration with Professor Yi Tang at the University of California, Los Angeles, Codexis conceived and developed a synthesis using an engineered enzyme and a practical, low-cost feedstock. Codexis optimized both the enzyme and the chemical process for the large-scale, commercial manufacture of simvastatin. The resulting process produces high quality simvastatin in a cost–effective manner and greatly reduces the use of hazardous chemicals and the amount of waste produced. “Collaborating with the Codexis team was a true inspiration. Their directed evolution technology empowered us to go beyond academic theory and deliver a more environmentally friendly process that is impacting the pharmaceutical industry today,” said Yi Tang, Professor, University of California Los Angeles. “Green chemistry and Codexis’ CodeEvolver™ directed evolution technology represent the future of cleaner, more efficient, and cost-advantaged pharmaceutical manufacturing processes. With the help of Professor Tang and his team, this award confirms Codexis’ role as an industry leader, and we are honored to be recognized for a third time by the EPA for our achievements,” said Gjalt Huisman, Ph.D., Vice President of Product Planning, Pharmaceuticals at Codexis. The process was scaled up at Codexis’ longstanding collaborator, Arch Pharmalabs Ltd., in Mumbai, India. Arch Pharmalabs manufactures a number of products for Codexis, including the 2006 Presidential Green Chemistry Challenge Award-winning process for atorvastatin, the active ingredient in Pfizer’s Lipitor ®. “We are running six biocatalytic processes developed by Codexis and have shown that they are reliably scalable and comparable to chemical processes, while offering significant advantages in terms of product purity, reduced waste, and reduced energy consumption,” said Dr. Ganesh Pai, Director of Research and Development, Arch Pharmalabs Ltd.
