Patent number: 11891614Abstract: Methods for developing engineered T-cells for immunotherapy that are both non-alloreactive and resistant to immunosuppressive drugs. The present invention relates to methods for modifying T-cells by inactivating both genes encoding target for an immunosuppressive agent and T-cell receptor, in particular genes encoding CD52 and TCR. This method involves the use of specific rare cutting endonucleases, in particular TALE-nucleases (TAL effector endonuclease) and polynucleotides encoding such polypeptides, to precisely target a selection of key genes in T-cells, which are available from donors or from culture of primary cells. The invention opens the way to standard and affordable adoptive immunotherapy strategies for treating cancer and viral infections.Type: GrantFiled: May 17, 2020Date of Patent: February 6, 2024Assignee: CELLECTISInventors: Roman Galetto, Agnes Gouble, Stephanie Grosse, Cecile Mannioui, Laurent Poirot, Andrew Scharenberg, Julianne Smith

Publication number: 20220348955Abstract: A method of expanding TCRalpha deficient T-cells by expressing pTalpha or functional variants thereof into said cells, thereby restoring a functional CD3 complex. This method is particularly useful to enhance the efficiency of immunotherapy using primary T-cells from donors. This method involves the use of pTalpha or functional variants thereof and polynucleotides encoding such polypeptides to expand TCRalpha deficient T-cells. Such engineered cells can be obtained by using specific rare-cutting endonuclease, preferably TALE-nucleases. The use of Chimeric Antigen Receptor (CAR), especially multi-chain CAR, in such engineered cells to target malignant or infected cells. The invention opens the way to standard and affordable adoptive immunotherapy strategies for treating cancer and viral infections.Type: ApplicationFiled: June 24, 2022Publication date: November 3, 2022Applicant: CellectisInventors: Roman GALETTO, Agnes GOUBLE, Stephanie GROSSE, Cecile MANNIOUI, Laurent POIROT, Andrew SCHARENBERG, Julianne SMITH
