On December 21, 2020 Ziopharm Oncology, Inc. ("Ziopharm" or "the Company") (Nasdaq: ZIOP), reported that the Taiwan Food and Drug Administration has cleared an investigational new drug application (IND) from Eden BioCell, a joint venture between Ziopharm and cell therapy company TriArm Therapeutics, for its phase 1 clinical trial to evaluate patient-derived CD19-specific CAR-T, using Ziopharm’s Rapid Personalized Manufacturing (RPM) technology (Press release, Ziopharm, DEC 21, 2020, View Source [SID1234573167]). This is an investigational treatment for patients with relapsed CD19+ leukemias and lymphomas and the first clinical study of autologous non-viral CD19-specific CAR-T in Taiwan.

This trial will utilize Ziopharm’s non-viral Sleeping Beauty cell engineering technology to infuse autologous CAR-T the day after T cells have been genetically modified. Ziopharm’s RPM CD19-specific CAR-T therapy results from the stable, non-viral insertion of DNA into the genome of resting T cells to co-express the chimeric antigen receptor (CAR), membrane-bound IL-15 (mbIL15) and a safety switch. The trial is being conducted at National Taiwan University Hospital.
"This study is a testament to the relationship Ziopharm has quickly established with Eden BioCell and TriArm and the progress using patients’ T cells under RPM to target malignancies," said Laurence Cooper, M.D., Ph.D., Chief Executive Officer of Ziopharm. "The results will help us understand the benefit of engineering T cells with membrane bound IL-15 which could benefit not only CAR-T, but also the engineering of T cells to express T-cell receptors."
Jay Zhang, Co-Founder and Chief Executive Officer of TriArm, added, "We are very excited to receive clearance of our IND in Taiwan. The learnings from this study will build upon the encouraging early data we are seeing with patients treated with RPM CAR-T targeting CD19 malignancies under compassionate use. We believe our approach has the potential to transform CAR-T therapy by dramatically decreasing the amount of time needed for manufacturing engineered T cells, thereby increasing efficacy and decreasing cost."
"CAR-T therapy has proved an effective therapy for B-cell cancers," noted Dr. Shang-Ju Wu, Division of Hematology, Department of Internal Medicine, National Taiwan University Hospital and Principal Investigator for the study. "Further optimization by shortening the manufacturing time would be of great importance to make this therapy more available to patients. We are honored to be involved in the clinical development of this non-viral CAR-T therapy produced using RPM. We hope the data derived from this current trial will advance CAR-T therapy to benefit our patients."
Up to 24 patients with relapsed CD19+ leukemias and lymphomas will be enrolled in this phase 1 trial, with the goal of infusing 16 subjects (Taiwan FDA #1096030182). The primary endpoint of the study is to evaluate the safety and tolerability of autologous CD19-specific T cells manufactured using the RPM process.
About Eden BioCell
In December 2018, Ziopharm and TriArm Therapeutics announced the launch of Eden BioCell to lead clinical development and commercialization of Sleeping Beauty-generated CAR-T therapies in Greater China. Ziopharm licensed the rights to Sleeping Beauty-generated CAR-T therapies targeting the CD19 antigen using Ziopharm’s RPM technology in Greater China to Eden BioCell. TriArm has committed up to $35 million to this joint venture, and Eden BioCell is owned 50-50 by Ziopharm and TriArm.
