Precision BioSciences and MaxCyte Enter into

Clinical and Commercial License Agreement

Precision BioSciences gains rights to MaxCyte's cell engineering technology to develop next-generation, oncology-focused, cell therapies with Precision's ARCUS® genome-editing technology

DURHAM, NC, and GAITHERSBURG, MD, 14 November 2018 - Precision BioSciences (Precision) and MaxCyte (LSE: MXCT, MXCR) today announced they have entered into a non-exclusive, clinical and commercial license agreement that will allow Precision to use MaxCyte's Flow Electroporation® technologies to robustly deliver Precision's proprietary ARCUS genome-editing technology for use in next-generation gene edited allogeneic T-cell immunotherapies designed to treat a broad range of cancers.

David Thomson, Chief Development Officer of Precision, expressed his support for the agreement, noting, "Precision's therapeutic grade ARCUS editing platform is sufficiently compact and specific to use with a range of delivery systems. In considering these, we have found MaxCyte's electroporation technology complements our approach to allogeneic T cell manufacturing, which is focused on preserving cell quality throughout the process while maximizing overall yield."

The clinical and commercial license builds upon an existing research and clinical license agreement between Precision and MaxCyte for the delivery of Precision's ARCUS technology into T-cells. MaxCyte will supply its technology platform to Precision as part of the license agreement and will receive future payments including milestones and technology access licensing fees.

"The initiation of this commercial license agreement with Precision, a leader in genome editing with its own proprietary ARCUS technology, signifies a key milestone for MaxCyte and demonstrates the value and versatility of our platform, our intellectual property, and our ability to foster important collaborations with companies generating life-changing gene therapies," said Doug Doerfler, President & CEO of MaxCyte, Inc.

MaxCyte's Flow Electroporation Technology enables the engineering of a variety of therapeutically-relevant cell types at high efficiency while maintaining high viability and recovery. Precision's lead allogeneic CAR T programs rely on genome editing, where ARCUS tools are used to transform healthy donor cells into therapeutics using the MaxCyte technology. These cell therapies can specifically target cancer cells in patients, potentially enabling a unique and specialized approach to cancer treatment.
