Precision BioSciences, Inc. (Nasdaq: DTIL), a clinical stage gene editing company developing ARCUS®-based ex vivo allogeneic CAR T and in vivo gene editing therapies, today announced that Dr. Raymond Schinazi is stepping down from the company’s Board of Directors and will continue as a member of the company’s SAB, lending his deep expertise in antiviral drug discovery and development.

“Ray is a trusted advisor, and since early 2019 when he joined the Board, has provided Precision with incredible perspective and support for the company’s CAR T and in vivo gene editing pipeline, particularly the development of ARCUS nucleases as an in vivo gene editing strategy to deliver a potential functional cure for chronic hepatitis B,” said Kevin Buehler, Chairman of the Board. “While we will miss having Ray on the Board, we look forward to continuing working with him as a SAB member. This change provides the opportunity for us to continue refreshing our Board with new independent directors that bring additional diverse experience and relevant expertise to Precision.”

“I’d like to thank Precision for the opportunity to work with an incredible team and a gene editing industry leader focused on developing potentially transformative treatment and curative options for high unmet needs,” said Dr. Schinazi. “I am confident the company will have continued success and I look forward to focusing my efforts on Precision’s SAB to further contribute to the development of its innovative in vivo pipeline, including a new, much-needed and potentially curative modality for chronic hepatitis B.”

Dr. Schinazi’s resignation from the Board of Directors was effective as of November 5, 2022.
