Abstract: Provided herein are proteins comprising a novel antigen binding domain. Said antigen binding domain, and proteins comprising it, are able to bind to osteosarcoma cells under physiological conditions. The antigen binding domain comprises an antibody light chain variable domain (VL) and an antibody heavy chain variable domain (VH), each comprising three complementarity determining regions (CDRs) flanked by human framework sequences. The human framework sequences reduces the risk of triggering unwanted immunogenic responses against the antigen binding domain. This may be especially important in a therapeutic setting wherein a drug is administered repeatedly to a human osteosarcoma patient.

Abstract: The present disclosure relates to compositions comprising compounds or cells able to specifically bind immunoglobulin kappa (IgKappa) and membrane molecule CD 19 under physiological conditions. In particular, the disclosure relates to a combinatorial chimeric antigen receptor (cCAR) with antigen binding domains specific for the antigen CD19 and the immunoglobulin (Ig) Kappa light chain and their expression in immune effector cells to target cells expressing CD19 and IgKappa, and such immune cells for use in treating B-cell cancers.

Abstract: Novel chimeric antigen receptors (CARs) are provided. When the CARs herein are expressed on the surface of immune cells, such immune cells may be directed to osteosarcoma cells as demonstrated with our in vivo data. In a murine intraperitoneal model, the tumor growth was significantly delayed for T cells expressing a CAR comprising a scFv from TP1 or TP3 antibodies. Immune cells expressing the CARs herein display therapeutic effect in the form of decreased tumor volume in a murine model simulating metastatic osteosarcoma. Combined with the finding that stem cells from healthy bone marrow were not significantly affected by T cells expressing any of the CARs, this disclosure provides an attractive cell therapeutic alternative for treatment of osteosarcoma.

Abstract: The present invention relates to a modified natural killer (NK) cell and its use in personalised medicine. The modified NK cells of the present invention are non-immunogenic, meaning that they are able to be administered to any recipient subject without being rejected by the host immune system (they are “universal”). In a first embodiment the non-immunogenic NK cells are modified to express CD3 to allow a T-cell Receptor (TcR) to be expressed. In a further embodiment the non-immunogenic NK cells are further modified to express a TcR together with the CD3 co-receptor. Co-expression of CD3 with a specific TcR results in the modified NK cells showing antigen-specific cytotoxicity towards target cells. Universal NK cells can thus be targeted against specific antigens, and may thus be used in personalised medicine, particularly in the field of oncology.
