NEW YORK, Oct. 31, 2023 (GLOBE NEWSWIRE) -- Cellectis (the “Company”) (Euronext Growth: ALCLS - NASDAQ: CLLS), a clinical-stage biotechnology company using its pioneering gene-editing platform to develop life-saving cell and gene therapies, announced today that pre-clinical data on MUC1-CAR T-cells to overcome key challenges of targeting solid tumors, will be presented at the Society for Immunotherapy of Cancer’s 38th Annual Meeting (SITC 2023), that will take place on November 1-5, 2023 at San Diego Convention Center in San Diego (CA).
The data will be presented by Laurent Poirot, Ph.D., SVP Immunology of Cellectis, in a poster session that will be held November 4th 2023 from 9:00 a.m. to 8:30 p.m. PDT, at San Diego Convention Center, Hall A.
The poster is number 254 and it is entitled “TGF-Beta Blockade Combined with Activation-Induced IL12 Secretion Synergize to Optimize Potency of MUC1-CAR T-cells in Preclinical Targeting of Triple-Negative Breast Cancer”.
While during SITC 2022 Cellectis presented how TALEN®-mediated gene editing allows programming of various functions addressing both safety and potency aspects of allogenic CAR T-cell therapy, this year the company’s presentation will focus on the synergistic benefits of ΔPD1-IL12 and TGFBR2-KO attributes in preclinical models of triple negative breast cancer.
“We demonstrate that combination of the ΔPD1-IL12 with TGFBR2 KO not only enhanced CAR-T cell activity but surprisingly limit their accumulation outside the tumor, therefore reducing the risks of off-tumor toxicity. These cells also show strong anti-tumor activity against distal tumors when infused intratumorally”, said Laurent Poirot, Ph.D., SVP Immunology at Cellectis.
These pre-clinical data highlight the capability of multi-armored allogeneic CAR T-cells to preserve their activity despite the immunosuppressive microenvironment, while mitigating potential safety concerns.
