Cellectis Appoints Stefan Scherer M.D., Ph.D., as Senior Vice President Clinical Development and Deputy Chief Medical Officer

NEW YORK--(BUSINESS WIRE)--August 2, 2018--Regulatory News:

Cellectis (Paris:ALCLS) (NASDAQ:CLLS) (Euronext Growth: ALCLS - Nasdaq: CLLS), a clinical-stage biopharmaceutical company focused on developing immunotherapies based on gene-edited allogeneic CAR T-cells (UCART), announced today the appointment of Dr. Stefan Scherer, M.D., Ph.D., to the role of Senior Vice President Clinical Development and Deputy Chief Medical Officer. Dr. Scherer joins Cellectis from Novartis Pharmaceuticals Corporation, where he was the Head of Early Development, Strategy and Innovation for U.S. Oncology. Dr. Scherer is based in New York and will report to Prof. Stéphane Depil, M.D., Ph.D., Executive Vice President Research & Development and Chief Medical Officer.

“Stefan’s deep medical expertise, strong track record of alliance- and relationship-building and previous C-level experience, all position him to make an immediate impact on the development and long-term strategic planning for Cellectis’ innovative product portfolio,” said Dr. André Choulika, Cellectis Chief Executive Officer. “As we continue to evolve our efforts to accelerate the access to patients of our off-the-shelf, gene-edited CAR T-cell product candidates, Stefan will be a key driver in the advancement of our product pipeline and programs overall.”

Dr. Scherer is a board-certified physician, bringing more than two decades of medical and scientific research and business experience from his time at various pharma and biotech companies to Cellectis. In his prior role as Head of Early Development, Strategy and Innovation for U.S. Oncology at Novartis, Stefan was responsible for the strategic direction and management of the Company’s immuno-oncology and targeted therapy portfolios. In addition, Stefan built a comprehensive clinical research alliance network and developed an immuno-oncology translational research team to harness scientific discovery for targeted patient outcomes.

Before Novartis, he served as Chief Medical Officer at Biocartis SA in Switzerland, where he was responsible for the medical development, marketing strategy and both business and academic partnerships. Prior to Biocartis, Dr. Scherer held key roles at F. Hoffman-La Roche / Genentech over the course of six years, as well as a number of other clinical and research roles of increasing responsibility.

"Given Cellectis’ powerful clinical momentum at this point in time, I am joining the Company at an exciting point in its evolution,” added Dr. Scherer. “I look forward to contributing my experience and expertise to further the development of Cellectis’ innovative CAR T product candidates that address what are truly some of the biggest health challenges of our time. I am also eager to work with my colleagues to advance the full potential of the Company’s unique technology for the benefit of patients and their families globally."
