Codexis, Inc., a leading enzyme engineering company enabling the promise of synthetic biology, today announced that the Company has entered into an agreement with Pfizer for the supply of a proprietary high-performance enzyme used to manufacture a critical intermediate for nirmatrelvir, an active pharmaceutical ingredient (API) in PAXLOVID™, Pfizer’s antiviral therapeutic, which is currently authorized for emergency use by the U.S. Food and Drug Administration (“FDA”) for the treatment of mild-to-moderate COVID-19 in people at high risk of progression to severe illness and authorized or approved by other regulatory authorities across the globe.

“Pfizer has played a critical role in the response to the global COVID-19 pandemic, including through their rapid development of PAXLOVID™, and I am incredibly proud that Codexis’ engineered enzyme is enabling a sustainable manufacturing route for their nirmatrelvir API,” said John Nicols, President and CEO of Codexis. “This agreement demonstrates the agility of Codexis’ commercial supply chain and manufacturing capabilities to very rapidly generate unprecedented enzyme quantities. We look forward to our continued support of Pfizer’s manufacturing of PAXLOVID™ for COVID-19 patients.”

“Codexis has been an extremely valuable partner throughout the scale-up of the nirmatrelvir process, and we are pleased to extend our partnership through this multi-year agreement,” said Pamela Siwik, Vice President, Launch Excellence, Pfizer Global Supply. “Their unique enzyme is an important element in the manufacture of PAXLOVID™ and plays a role in supporting our efforts to ensure rapid availability of this COVID-19 oral treatment to people around the world.”
