Human CAR+ T cells with membrane-bound IL-15 manufactured in less than two days exhibited anti-tumor activity and persistence in pre-clinical studies
BOSTON, MA, USA I February 12, 2018 I Ziopharm Oncology, Inc. (Nasdaq:ZIOP), a biotechnology company focused on development of next generation immunotherapies utilizing gene- and cell-based therapies to treat patients with cancer, today announced data demonstrating point-of-care (P-O-C) manufacturing of human T cells expressing chimeric antigen receptor (CAR) that persist and have an anti-tumor effect in preclinical models were presented at the Keystone Symposia Emerging Cellular Therapies: T Cells and Beyond in Keystone, Colorado.
The data presented showed T cells expressing CD19-specific CAR with membrane-bound IL-15 (mbIL15) were generated with the non-viral Sleeping Beauty system in less than two days and did not require ex vivo activation or propagation. T cells designed to express mbIL15 showed greater persistence and more potent antitumor activity than comparator T cells without mbIL15 in these studies.
Lenka V. Hurton, Ph.D., a researcher in the Division of Pediatrics at the University of Texas MD Anderson Cancer Center, presented the findings in a talk entitled, "Rapid production of T cells co-expressing CAR and membrane-bound IL-15 potentiates antitumor activity and promotes in vivo memory." She also presented a poster under the same title during the Keystone Symposia.
Ziopharm is advancing its non-viral Sleeping Beauty platform towards using its point-of-care, or P-O-C, technology, a very rapid manufacturing process of genetically modified CAR+ T cells co-expressing mbIL15, with the first in-human trial utilizing this approach expected to commence in 2018. Ziopharm believes that manufacturing under P-O-C has the potential to reduce the costs associated with T-cell therapies and the potential to broaden application based on avoiding the need for centralized manufacturing as is the case when using a virus to genetically modify T cells.
Dr. Hurton's poster and presentation slides are based on research conducted in collaboration with The University of Texas MD Anderson Cancer Center and Precigen Inc., a wholly-owned subsidiary of Intrexon Corporation (NYSE:XON). The poster is available in the Presentations and Publications section of the Company's website, www.ziopharm.com.
About Ziopharm Oncology, Inc.
Ziopharm Oncology is a Boston-based biotechnology company focused on development of next-generation immunotherapies utilizing gene- and cell-based therapies to treat patients with cancer. In partnership with Precigen Inc., a wholly-owned subsidiary of Intrexon Corporation (NYSE:XON), Ziopharm is focused on the development of two platform technologies designed to deliver safe, effective and scalable cell- and viral-based therapies for the treatment of multiple cancer types: Controlled IL-12 and Sleeping Beauty for genetically modifying T cells. The Company's lead asset, Ad-RTS-hIL-12 plus veledimex, has demonstrated in clinical trials the potential to control interleukin-12, leading to an infiltration of T cells that fight brain cancer. The Company also is advancing therapies using Sleeping Beauty, a non-viral approach to genetically modify chimeric antigen receptor (CAR+) and T-cell receptor (TCR+) T cells, which target specific antigens in blood cancers and neoantigens solid tumors. Sleeping Beauty is designed using the Company's point-of-care technology, a shortened manufacturing process which potentially can be developed as a decentralized manufacturing process based in hospitals. These programs are being advanced in collaboration with Precigen and with MD Anderson Cancer Center, the National Cancer Institute and Merck KGaA, Darmstadt, Germany.
