Press Release
Posted on: twenty eight Jul 17
RANCHO CORDOVA, Calif., July 28, two thousand seventeen (GLOBE NEWSWIRE) — Cesca Therapeutics Inc. (NASDAQ:KOOL), a market leader in automated cell processing, today announced that the U.S. Patent and Trademark Office has awarded a fresh U.S. Patent, No. 9,695,394 (the вЂ394 patent’), entitled “Cell Separation Devices, Systems, and Methods.” The patent was awarded to SynGen, Inc., whose cell processing assets were acquired by ThermoGenesis Corp., Cesca’s 80%-owned device subsidiary, on July Ten, 2017. The patent relates to the automated isolation of uncommon, therapeutically critical target cells from blood, bone marrow, leukapheresis product, and other cell sources, while maintaining the viability of the cells under asceptic conditions. This advanced technology is part of Cesca’s proprietary CAR-TXpressв„ў platform that now integrates multi-component automation steps, including T-cell isolation, purification, culture expansion and washing, and single cassette-based automated -196В°C cryopreservation and retrieval. The CAR-TXpressв„ў system provides a comprehensive and commercially viable, automated cellular manufacturing and control (CMC) solution for the development of CAR-T and CAR-NK therapeutics.
“This fresh patent issuance significantly strengthens the intellectual property position surrounding our proprietary automation technology which is core to our best-in-class ThermoGenesis portfolio of cell processing systems,” said Chris Xu, Cesca’s chief executive officer. “Traditional cell processing methodologies, including those presently being implemented and used by leading CAR-T developers, are manual and time consuming, presenting significant challenges to the future large-scale commercial feasibility of these revolutionary therapies. In contrast, Cesca’s patented, automated cell processing systems provide greater cell yields and higher consistency in a fraction of the time, making them ideally suited to meet industry needs. The capability to leverage our technology to commercialize the BACS process is a milestone achievement for our company.”
Cesca’s вЂ394 patent covers a device and methodology for integrating automated cellular separation and buoyancy-activated cell sorting (BACS) processes. BACS employs microscopic bubbles to isolate a specific cell type from a sophisticated combination of cells, such as blood. These microbubbles bear antibodies on their surface, enabling them to truss specifically to a single desired target cell type. When decorated with microbubbles, the target cells float to the top of the host liquid, while non-target cells drown to the bottom – a process that can be accelerated by centrifugation. Subsequent collection of the floating target cell layer and release of the cells from their microbubbles provides a highly-purified prep of just the cells of interest, with high recovery efficiency while retaining cell viability. Additionally, the вЂ394 patent permits for the automated isolation of cells with low density surface antigens, which was previously a major cellular manufacturing challenge.В
“Cesca’s unique CAR-TXpressв„ў cell processing solution embarks with BACS-based cell isolation technology to provide the ultra-high levels of cell purity, recovery, and viability of target immune cells from donor blood that therapeutic cell manufacturers increasingly request,” said Philip Coelho, chief technology officer of ThermoGenesis and co-inventor of the вЂ394 patent. “Unlike conventional cell isolation technologies that work on narrow flows of leisurely moving suspended cells, our BACS-enabling technology works in bulk volumes of cells, dramatically reducing processing time. With these advantages, we look forward to partnering with leading CAR-T developers as they strive to bring these groundbreaking therapies to patients suffering from cancer and other serious diseases.”
