Renowned Geneticist to Chair Poseida Therapeutics Gene Therapy Scientific Advisory Board

SAN DIEGO, July 26, 2022 /PRNewswire/ -- Poseida Therapeutics, Inc. (Nasdaq: PSTX), a clinical-stage biopharmaceutical company utilizing proprietary genetic engineering platform technologies to create cell and gene therapeutics with the capacity to cure, today announced the appointment of geneticist George M. Church, Ph.D., who will serve as Chair of Poseida's newly formed Gene Therapy Scientific Advisory Board (SAB). Together with the Company's Immuno-Oncology SAB, which is led by Chair Carl June, M.D., the Gene Therapy SAB will provide advice and counsel on the research and development efforts that drive the Company's innovative gene therapies.

"We are honored to have Dr. Church, a pioneer in the fields of genome engineering, systems biology and synthetic biology, join Poseida's Scientific Advisory Board. As we continue to develop the next wave of cutting-edge gene therapies, we will benefit from advisors with expertise that serves specific aspects of our portfolio," said Eric Ostertag, M.D., Ph.D., Executive Chairman of Poseida Therapeutics. "Dr. Church's depth of knowledge and experience, both in academia and industry, will make him a tremendous asset as Chair of our newly created Gene Therapy Scientific Advisory Board and we look forward to working with him as we build out this group of advisors."

"The rapidly evolving science of gene editing offers tremendous opportunities to address a wide range of diseases using non-viral gene editing approaches," said Dr. Church. "There's never been more exciting time to explore the many possibilities of gene editing for solving some of the most pressing medical and scientific challenges of our time."

Poseida is currently developing a number of gene therapies addressing rare and life-threatening diseases such as ornithine transcarbamylase (OTC) deficiency and Hemophilia A, two genetic diseases usually diagnosed early in life. These therapies utilize the Company's proprietary genetic engineering platform technologies, including its Cas-CLOVER™ Site-specific Gene Editing System and piggyBac® DNA Delivery System, in combination with nanoparticle technology, for highly efficient integration that may result in potential single treatment cures.

"As we develop in vivo gene therapies for rare diseases in patient populations with high unmet medical need, I am thrilled to have Dr. Church lead our Gene Therapy SAB," said Brent Warner, President, Gene Therapy at Poseida. "We welcome his guidance and expertise as we accelerate our non-viral gene therapy programs for patients in need."

About George M. Church, Ph.D.

George Church is a pioneer in the fields of genetics and synthetic biology.  He is the director of PersonalGenomes.org, which provides open-access information on human Genomic, Environmental & Trait data (GET). His 1984 Ph.D. included the first methods for direct genome sequencing, molecular multiplexing and barcoding. These led to the first genome sequence (pathogen, Helicobacter pylori) in 1994. His innovations have contributed to nearly all "next generation" DNA sequencing methods and companies. In addition, his lab's work on chip-DNA-synthesis, gene editing and stem cell engineering resulted in founding additional application-based companies spanning fields of medical diagnostics and synthetic biology and therapeutics. He has also pioneered new privacy, biosafety, ethical, legal, and social issues (ELSI), environmental and biosecurity policies. He is director of an Intelligence Advanced Research Projects Activity (IARPA) BRAIN Project and National Institutes of Health (NIH) Center for Excellence in Genomic Science. His honors include election to the National Academy of Sciences, National Academy of Engineering and receiving the Franklin Bower Laureate for Achievement in Science. He has coauthored 590 papers, 155 patent publications and a book (Regenesis).
