Sangamo Therapeutics and Chroma Medicine Announce Option and License Agreement to Evaluate and Develop Zinc Finger Proteins for Epigenetic Editing

Sangamo Therapeutics, Inc. (Nasdaq: SGMO), a clinical-stage genomic medicine company and Chroma Medicine, Inc. (Chroma), a genomic medicine company pioneering single-dose epigenetic editing therapeutics, today announced they have entered into a research evaluation, option and license agreement to develop epigenetic medicines leveraging zinc finger proteins (ZFPs) for sequence-specific DNA recognition. Over the course of two decades, Sangamo has built and validated the world’s largest library of ZFPs, deploying them to address numerous therapeutically relevant targets. Advancing the transformative potential of epigenetic editing, Chroma is expanding the versatility of its platform by leveraging Sangamo’s ZFPs. Following a research evaluation period, Chroma has the option to license the ZFPs for potential worldwide development and commercialization of epigenetic medicines for certain therapeutic targets.

“Sangamo is the world leader in zinc finger protein genomic engineering, and we are very proud of the range and depth of our capabilities in this area,” said Jason Fontenot, Ph.D., Chief Scientific Officer at Sangamo. “We believe our ability to rapidly design and engineer highly potent and specific ZFPs can provide unique and highly valuable capability beyond what is available with competing technologies. We are constantly seeking to deploy our technology with partners outside of our core neurology focus area and are very happy to explore combining our ZF technology with Chroma’s unique capabilities. We believe that this work will further validate the importance of zinc fingers as an ideal platform to support epigenetic editing.”

Under the terms of the agreement, Chroma will evaluate novel Sangamo ZFPs for specified collaboration targets outside of the central nervous system in exchange for an upfront technology access payment. If Chroma exercises its option for any or all targets, Sangamo would be eligible to receive an option exercise payment, in addition to potential development and commercial milestone payments, as well as royalties on any Chroma products incorporating the licensed ZFPs. Chroma will lead and fund all research, development, manufacture, and commercialization of products incorporating the licensed Sangamo ZFPs.
