Cellectis Presents Research Data on a Novel Immune-Evasive Universal CAR T-cell at ASGCT
NEW YORK, May 16, 2022 (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, today will present its first research data on the development of a novel universal CAR T-cell with immune-evasive properties using TALEN®-gene editing, at the American Society of Cell and Gene Therapy Annual Meeting (ASGCT) being held on May 16-19, 2022. This novel immune-evasive CAR T-cell scaffold evades NK (Natural Killer) cell and alloresponsive T-cell attacks and imparts efficient antitumor activity in vitro and in vivo.
Cellectis’ novel immune-evasive CAR T-cell (ΔTRACCARΔB2MHLAE), was developed using a combination of TALEN®-mediated gene editing and adeno-associated virus (AAV) dependent gene insertion. ΔTRACCARΔB2MHLAE is devoid of TCRαβ and human leukocyte antigen (HLA) Class I expression and endowed with an engineered surface-exposed HLA-E. These three features could enable CAR T-cells to prevent graft versus host (GvH) reaction and evade the cytolytic activities from alloresponsive T-cells and NK cells.
"Universal CAR T-cell therapies are poised to revolutionize cancer treatment and to improve patient outcomes. Realizing these advantages in an allogeneic setting requires universal CAR T cells that can kill target tumor cells, avoid depletion by the host immune system, and proliferate without attacking host tissues. Cellectis’ research suggested that ΔTRACCARΔB2MHLAE T-cells evade NK cell and alloresponsive T-cell attacks and showed prolonged antitumor activity in the presence of cytotoxic levels of NK cells. This new cellular scaffold could enable the broad use of universal CAR T-cells in allogeneic settings and holds great promise for clinical applications," said Julien Valton, Ph.D., Vice President Gene Therapy at Cellectis.
