From Startup Ziopharm Oncology
BOSTON, Dec. 27, 2018 (GLOBE NEWSWIRE) — Ziopharm Oncology, Inc. (Nasdaq:ZIOP) today responded to the recent decline in the Company’s stock price, which accelerated greatly on December 26, 2018, the same day that the broader market and all indexes were up significantly. To the extent this price drop may have been attributable to any market confusion over exclusivity to its assets, the Company wishes to make clear the terms of its exclusivity to such assets.
“Our stock price is significantly down of late, and we want to assure the market that our business fundamentals are unchanged and we are optimistic about Ziopharm’s future especially in light of the recent announcements we made with regards to our restructured relationship with Intrexon, the securing of a clean and longer-term balance sheet, and two partnerships with Regeneron and Eden BioCell. We believe it is important to respond urgently,” said Laurence Cooper, M.D., Ph.D., Chief Executive Officer of Ziopharm. “We want to clarify the record around the programs and assets where we have exclusivity.”
Over approximately the last three years, Ziopharm and Intrexon (and later Precigen) mutually agreed to focus their collaborative efforts on four pipeline components: 1. Sleeping Beauty TCR-T cell therapy with the National Cancer Institute (NCI); 2. Sleeping Beauty CD19 CAR-T at The University of Texas MD Anderson Cancer Center; 3. Ad-RTS-hIL-12 plus veledimex in multi-center trials; and 4. CD33 as a potential CAR target at MD Anderson. In addition, one of the key elements for very-rapid manufacture of T cells genetically modified with the Sleeping Beauty platform is membrane-bound interleukin 15, or mbIL15, which was invented by Dr. Cooper’s team at MD Anderson and licensed to Ziopharm and Intrexon.
On Oct. 9, 2018, Ziopharm and Intrexon (Precigen) announced details of a new licensing agreement that reset the relationships between the companies. Ziopharm now holds exclusive rights for the treatment of cancer for items 1, 2 and 3 as detailed below:
For Sleeping Beauty intellectual property for all TCRs, including specificity for neoantigens and shared antigens; Sleeping Beauty-generated TCR-T cell therapy targeting neoantigens in solid tumors is being developed in collaboration with NCI, which expects to begin treating patients in a phase 1 trial in mid-2019;
Sleeping Beauty-generated CAR-T cell therapy targeting the CD19 antigen with mbIL15 and a kill switch, which is advancing to a clinical trial with two-day T-cell manufacturing in 2H2019;
Controlled IL-12 platform (Ad-RTS-hIL-12 plus veledimex); Ziopharm has multiple trials with this asset as a monotherapy and in combination with immune checkpoint inhibitors underway and/or planned for 2019.
Ziopharm holds exclusive rights to a second, unnamed target for Sleeping Beauty CAR-T therapy and is evaluating its rights to pursue this target following Precigen’s assumption of ARES Trading S.A.’s rights under the parties’ collaboration agreement. During negotiations Ziopharm agreed to release CD33, the fourth pipeline component, to Precigen.
Precigen cannot use the Sleeping Beauty platform intellectual property for TCRs in T cells that has been licensed to Ziopharm, and Precigen cannot research or develop any TCR therapies that target neoantigens (i.e., individual, patient-specific antigens) for three years, under the license agreement. In addition, Precigen cannot use another regulatable switch technology to conditionally express IL-12 for three years for the treatment of cancer.
“Ziopharm’s rights to Sleeping Beauty TCR- and CAR-T cell therapies, IL-12 with the RheoSwitch and membrane-bound interleukin 15 are clear, and we are committed to protecting our intellectual property and these assets,” said David Mauney, M.D., President of Ziopharm.
Dr. Cooper added, “We expect all three programs will be in the clinic in 2019. As for our agreement with Intrexon and Precigen, it is important to remind our shareholders that we sought this separation and we negotiated for the assets we wanted most.”
