�Qihan Biotech Expands Scientific Advisory Board and Establishes Scientific Advisory Committees

HANGZHOU, China–(BUSINESS WIRE)–Qihan Biotech, a leader in applying genome editing technology to cell therapies and organ transplantation, today announced the expansion of its Scientific Advisory Board to include a total of 12 world-renowned experts in synthetic biology, regenerative medicine, transplantation immunology and cell therapy, as well as the formation of several Scientific Advisory Committees.

Qihan was founded in 2018 to develop novel cell and organ therapies using multiplexable genome editing and expertise in transplantation immunology. Co-founder Luhan Yang, Ph.D., a co-inventor of the CRISPR-Cas9 technology, currently serves as Qihan�s Chief Executive Officer. Co-founder George Church, Professor of Genetics at Harvard Medical School and Professor of Health Sciences and Technology at Harvard and the Massachusetts Institute of Technology (MIT), currently serves as the Co-Chairman of Qihan’s Scientific Advisory Board. The company raised two rounds of financing to advance its cell therapy programs into preclinical research.

“As Qihan leverages its gene editing and transplantation immunology expertise to create enhanced allogeneic cell therapies, we saw the need to expand our Scientific Advisory Board and add experts in cell therapy, transplantation and the regulatory and commercial considerations of genome-edited treatments,” said Luhan Yang, Ph.D., CEO of Qihan Biotech. “We welcome these distinguished scientists and clinicians to our Scientific Advisory Board and look forward to integrating their knowledge and guidance.”

George Church, Co-founder of Qihan Biotech and Co-Chairman of the Scientific Advisory Board, said, “We’re looking forward to leveraging the deep scientific expertise and insights this elite group brings to bear on the design and development of both immune-privileged, human stem cell-derived allogeneic cell therapies and xenogeneic organ products.”

The selected members and committees of Qihan Biotech’s Scientific Advisory Board are as follows:

Scientific Advisory Board Co-Chairs

George Church, Ph.D., Professor of Genetics at Harvard Medical School, a founding member of the Wyss Institute, and Director of PersonalGenomes.org, the world’s only open-access information on human genomic, environmental and trait data. Church is known for pioneering the fields of personal genomics and synthetic biology. He developed the first methods for the first genome sequence and has facilitated dramatic cost reductions since then, contributing to nearly all “next generation sequencing” methods and companies. His team invented CRISPR for human stem cell genome editing and other synthetic biology technologies and applications – including new ways to create organs for transplantation, gene therapies for aging reversal, and gene drives to eliminate Lyme disease and malaria. He is Director of the Intelligence Advanced Research Projects Activity and the National Institutes of Health (NIH) BRAIN Projects, as well as the NIH Center for Excellence in Genomic Science. He has co-authored more than 515 papers and 130 patent publications, and one book, “Regenesis.” His honors include the Franklin Bower Laureate for Achievement in Science, nomination to the TIME 100 and election to the National Academies of Sciences and Engineering.

James F. Markmann, M.D., Ph.D., Chief of the Division of Transplant Surgery and Director of Clinical Operations at the Transplant Center at Massachusetts General Hospital, and the Claude Welch Professor of Surgery at Harvard Medical School. He specializes in liver, kidney, pancreas and islet transplantation. He has published more than 300 scientific papers over the last 30 years, has held continuous NIH R01 funding for >20 years and is currently President of the International Pancreas and Islet Transplant Association. His current research interests include: 1) understanding the mechanism of action and therapeutic potential of regulatory B cells, 2) exploring the potential of ex vivo liver perfusion to improve marginal organ function, and 3) translational studies in xenotransplantation with the goal of clinical application.

Scientific Advisory Board Members, Committee on Cell Therapies

Dan Kaufman (Chair of Cell Therapy Committee), M.D., Ph.D., Professor of Medicine, Division of Regenerative Medicine and Director of Cell Therapy at University of California San Diego (UCSD). His research focuses on use of human pluripotent stem cells to study basic mechanisms that regulate early human blood cell development and to derive therapeutic mature blood cell populations. The aim is to use human pluripotent stem cells as a resource to produce blood and immune cells for new clinical applications for treatment of relapsed/refractory cancers – both hematologic malignancies and solid tumors.

Hiromitsu Nakauchi, M.D., Ph.D., Professor, Department of Genetics and the Institute for Stem Cell Biology and Regenerative Medicine, Stanford University School of Medicine. His research focuses on translation of discoveries in stem cell biology, immunology, molecular biology and developmental engineering to create effective stem cell therapies. He earned his medical degree from Yokohama City University School of Medicine and a Ph.D. in immunology from the University of Tokyo Graduate School of Medicine.

Scientific Advisory Board Members, Committee on Transplantation Immunology

Qizhi Tang, Ph.D., Professor of Surgery in Division of Transplant Surgery and Director of the Transplantation Research Laboratory at the University of California, San Francisco (UCSF). The major research focus in the Tang Lab is on regulatory T cell therapy for autoimmune diseases and transplantation. Since 2011, she has also been co-directing the regulatory T cell therapy program at UCSF, which has supported 10 early-phase clinical trials in type 1 diabetes, pemphigus, islet transplantation, kidney transplantation and liver transplantation. Another area of research in the Tang Lab is on optimizing islet transplantation to enable highly efficient immunosuppression-free replacement of pancreatic beta cells for the treatment of type 1 diabetes. Dr. Tang received her Ph.D. in immunology from the University of Illinois at Chicago. She completed postdoctoral fellowships investigating mechanisms of immune tolerance at the University of Chicago and UCSF.
