MELBOURNE, Australia, GERMANTOWN, Md. and BOSTON, Oct. 23, 2013 (GLOBE NEWSWIRE) -- Mesoblast Limited (ASX:MSB), a world leader in the development of cell-based biologic products, Intrexon Corporation (NYSE:XON), a leader in synthetic biology, and ZIOPHARM Oncology, Inc. (Nasdaq:ZIOP), a biopharmaceutical company focused on the discovery and development of new cancer therapies, today announced a partnership to develop a new class of cancer therapeutics.
Under the terms of the agreement the companies will combine Mesoblast's proprietary Mesenchymal Lineage Cells (MLCs) with Intrexon's RheoSwitch Therapeutic System® (RTS®) platform to co-develop complex transgene enabled cell-based treatments for oncology applications. The goal of combining these technologies is to enable development of therapeutic candidates in the treatment of cancer which exhibit both specific tumor targeting characteristics and controlled gene expression. The partnership is a 50/50 collaboration between Mesoblast and Ziopharm, with Intrexon participating through its Exclusive Channel Collaboration with Ziopharm. If successful in feasibility studies targeting lung cancer, the companies expect to form a joint venture to advance development of therapeutic candidates.
Randal J. Kirk, Chairman and Chief Executive Officer of Intrexon Corporation, noted that the initial studies and subsequent joint venture will bring together unique Intrexon technology, Mesoblast cell technology and production expertise and ZIOPHARM development expertise.
"The combination of expertise, technologies and production capabilities represented by Mesoblast, ZIOPHARM, and Intrexon is an excellent example of how collaborations will be expanded into new areas of therapeutic research and development," Kirk said. "Through this program each party has an essential role that is indispensable to its advancement and hopefully to the development of more effective cancer therapies."
Silviu Itescu, Chief Executive Officer of Mesoblast Limited, said: "MLCs modified with RTS® technology could be ideal vehicles to deliver therapeutic transgenes to targeted tumors at specific sites in the body. Additionally, our cells can be commercially manufactured to industrial scale for clinical use as they are readily expanded to large numbers in culture, can be used in allogeneic recipients without the need for matching or immunosuppression, and are available cryopreserved for off-the-shelf use.
"By seeking to develop anti-cancer effectors using our proprietary MLCs, we are now expanding the focus of our oncology therapeutic area beyond the field of bone marrow transplants and the treatment of its major complication, acute graft-versus-host disease. If this complex cell plus transgene approach is successful for lung cancers, the technology will be explored for the treatment of other cancers," Itescu said.
In initial studies, ZIOPHARM will leverage Intrexon's UltraVector® platform to design and optimize therapeutic gene expression in MLCs to mediate an anti-cancer effect against lung cancer. Intrexon's RTS® platform will also be utilized for inducible control over the amount and timing of therapeutic gene expression providing precise regulation for MLC delivered therapies.
Jonathan Lewis, M.D., Ph.D., chief executive officer of ZIOPHARM Oncology, Inc. said, "The ability of Intrexon's RTS® platform to induce and regulate expression of anti-cancer effectors through dosing with an activator has been demonstrated in current Phase 2 studies for the treatment of advanced melanoma and breast cancer1. By integrating Mesoblast's MLC platform into our therapeutic complex transgene research and development program, we hope to target advanced non-small-cell lung cancer and advance a new field of cell-based therapies."
"Lung cancer represents a significant unmet medical need," said Samuel Broder, M.D., Senior Vice President of Intrexon's Health sector and former Director of the National Cancer Institute. "The co-development of complex RTS® regulated transgenes and cell-based therapy into a novel treatment means lung cancer cells could be attacked simultaneously in two dimensions. The first is through the delivery of the modified MLCs to the lung tissue. The second is through Intrexon's proven RheoSwitch® technologies in which therapeutic transgenes are expressed under the control of a small molecule activator, permitting MLCs to deliver antitumor proteins to sites where they are needed. Delivery plus expression and regulation should prove to be powerful combination."
According to the United States National Cancer Institute, it is estimated that 228,190 patients will be diagnosed with lung cancer, and nearly 160,000 patients will die of this disease in 2013. Lung cancer is the leading cause of cancer death in both men and women in the United States. Lung cancer causes more cancer-related deaths than the next three most common cancers combined (colon, breast and prostate).
