Abstract: The present invention relates to methods for developing engineered T-cells for immunotherapy that are non-alloreactive. The present invention relates to methods for modifying T-cells by inactivating both genes encoding T-cell receptor and an immune checkpoint gene to unleash the potential of the immune response. 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.

Abstract: Methods of developing genetically engineered immune cells for immunotherapy, which can be endowed with Chimeric Antigen Receptors targeting an antigen marker that is common to both the pathological cells and said immune cells (ex: CD38, CS1 or CD70) by the fact that the genes encoding said markers are inactivated in said immune cells by a rare cutting endonuclease such as TALEN, Cas9 or argonaute.

Abstract: The present invention relates to methods of developing genetically engineered, preferably non-alloreactive T-cells for immunotherapy. This method involves the use of RNA-guided endonucleases, in particular Cas9/CRISPR system, to specifically target a selection of key genes in T-cells. The engineered T-cells are also intended to express chimeric antigen receptors (CAR) to redirect their immune activity towards malignant or infected cells. The invention opens the way to standard and affordable adoptive immunotherapy strategies using T-Cells for treating cancer and viral infections.

Abstract: 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.
