Ziopharm Oncology Presents Preclinical Data Supporting TCR-T Library Approach at the Society for Immunotherapy of Cancer 2021 Annual Meeting
HOUSTON, Nov. 09, 2021 (GLOBE NEWSWIRE) -- Ziopharm Oncology, Inc. (“Ziopharm” or the “Company”) (Nasdaq: ZIOP), today announced the presentation of preclinical data highlighting the potential of neoantigen-specific TCR-T cells for the treatment of solid tumors at the Society for Immunotherapy of Cancer 2021 Annual Meeting.
“We are pleased to share preclinical data demonstrating the versatility of our Sleeping Beauty technology to develop neoantigen-specific TCR-T cells with the potential to address a wide range of solid tumor indications,” commented Raffaele Baffa, M.D., Ph.D., Chief Medical Officer & EVP, Research & Development. “Our TCR-T library approach allows us to develop safe, effective and durable therapies for any patient with a matching neoantigen/HLA combination within our library. We are working diligently to initiate our Phase 1/2 TCR-T Library trial in the first half of 2022 as well as continue to expand our library of TCRs in order to increase the pool of eligible patients who could benefit from these therapies.”
Details of Ziopharm’s SITC 2021 presentation are as follows:
Title:Neoantigen-specific TCR-T cells targeting shared hotspot mutations for adoptive cell therapy in common epithelial cancers
Presenter: Drew Deniger, Ph.D., Ziopharm Oncology
Date/Time: Saturday, Nov. 13, 2021 from 7:00 a.m. – 8:30 p.m. ET
Location: Walter E. Washington Convention Center, Hall E
Abstract Number: 226
In the study presented at SITC, Ziopharm’s non-viral gene transfer technology, Sleeping Beauty, was used to develop TCR-T cells targeting EGFR, KRAS and p53 neoantigens, which are present in cancer cells but not in normal tissue, and are presented by a variety of human leukocyte antigen (HLA) molecules on the cancer cell surface. Ziopharm’s Sleeping Beauty technology exhibited greater than 60% expression of the introduced neoantigen-specific TCRs in the generated TCR-T cells. The study demonstrated that the neoantigen-specific TCR-T cells successfully targeted tumor cells expressing EGFR, KRAS and p53 neoantigens in conjunction with the matching HLA restriction. Importantly, these TCR’s did not recognize cells lacking the matching mutations and HLA restrictions.
