Kite, a Gilead Company, and Sangamo Therapeutics Announce Collaboration to Develop Next-Generation Engineered Cell Therapies for the Treatment of Cancer

-- Kite to Receive Exclusive License to Leverage Sangamo’s Gene Editing Technology in Allogeneic and Autologous Cell Therapy Programs in Oncology --

SANTA MONICA, Calif. & RICHMOND, Calif.--()--Kite, a Gilead Company (Nasdaq:GILD) and Sangamo Therapeutics, Inc. (Nasdaq:SGMO) today announced the companies have entered into a worldwide collaboration using Sangamo’s zinc finger nuclease (ZFN) technology platform for the development of next-generation ex vivo cell therapies in oncology.

Kite will use Sangamo’s ZFN technology to modify genes to develop next-generation cell therapies for autologous and allogeneic use in treating different cancers. Allogeneic cell therapies from healthy donor cells or from renewable stem cells would provide a potential treatment option that can be accessed directly within the oncology infusion center, thus reducing the time to infusion for patients.

Under the terms of the agreement, Sangamo will receive an upfront payment of $150 million and is eligible to receive up to $3.01 billion in potential payments, aggregated across 10 or more products utilizing Sangamo’s technology, based on the achievement of certain research, development, regulatory and successful commercialization milestones. Sangamo would also receive tiered royalties on sales of potential future products resulting from the collaboration. Kite will be responsible for all development, manufacturing and commercialization of products under the collaboration, and will be responsible for agreed upon expenses incurred by Sangamo.

This collaboration between Kite and Sangamo brings together two leading platforms to develop best-in-class cell therapies in oncology,” said Sandy Macrae, President and Chief Executive Officer of Sangamo. “We are excited by Kite’s commitment to driving innovation in this field and look forward to working together to realize the full promise of cell therapy in treating cancer.”

The emergence of gene editing as a tool to edit immune cells holds promise in the development of therapies with potentially improved safety, efficacy and efficiency,” said John F. Milligan, PhD, Gilead’s President and Chief Executive Officer. “We believe Sangamo’s zinc finger nucleases provide the optimal gene editing platform, and we look forward to working with Sangamo to accelerate our efforts to develop next-generation autologous cell therapies, as well as allogeneic treatments that can be accessed more conveniently in the hospital setting for people living with cancer.”

This transaction is subject to clearance under the Hart-Scott Rodino Antitrust Improvements Act and other customary closing conditions. A Current Report on Form 8-K describing the proposed transaction in more detail will be filed by Sangamo, and this press release is subject to further detail provided in Sangamo’s 8-K.
