Abstract: The present disclosure is related to improved methods for use of a humanized binding polypeptide specific for the alpha beta T cell receptor (??-TCR). In particular, this disclosure relates to improved methods of use of a humanized anti-??-TCR antibody, which is derived from the murine monoclonal antibody BMA031, in immunosuppressive therapy. Novel methods using humanized monoclonal antibodies and/or humanized monoclonal antibody fragments (e.g., anti-??TCR antibodies and/or fragments thereof) are also provided. Novel methods using repetitive administration of humanized monoclonal antibodies and/or humanized monoclonal antibody fragments (e.g., anti-??TCR antibodies and/or fragments thereof) to reduce ?? T cells in the subject relative to ?? cells in the subject are provided.

Abstract: The present invention provides an extracellular anti-linker/label epitope chimeric antigen receptor (anti-LLE CAR) comprising I) a linker/label epitope (LLE) binding domain, II) a transmembrane domain, and III) a signal transduction domain, wherein said extracellular LLE binding domain binds a target cell binding molecule (TCBM) comprising i) an antigen binding moiety (ABM), wherein said ABM binds specifically to an antigen expressed on a target cell, ii) a label moiety (LaM), wherein said LaM is a naturally occurring molecule in a subject or a derivative thereof, iii) a linker moiety (LiM) conjugating said ABM and said LaM, thereby forming a linker/label epitope (LLE), wherein said extracellular LLE binding domain binds said LLE with a higher preference than said naturally occurring molecule.

Abstract: The invention is directed to cancer immunotherapy. The invention is specifically directed to the induction of innate or adaptive antitumor immunity initiated by the administration of targeted IL-12 molecules preferably in conjunction with IL-2 and/or IL-7 to a cancer patient, who suffers from cancer of the muscle, bone, nerves, cartilage, tendons, blood vessels, etc., preferably from sarcoma. The invention is specifically related to the use of IL-12 in form of the specific immunoglobulin cytokine fusion protein called NHS-IL12, preferably in combination with a form of IL-2 and/or IL-7 exhibiting prolonged pharmacokinetics for the treatment of said cancer diseases.

Abstract: The invention relates to a composition, comprising a cell population that can be obtained from bone marrow or from blood, when the cell population is depleted of cells that express TCR alpha/beta and cells that express CD19. Such a pharmaceutical composition makes the reconstitution of the immune defense of a person as part of a bone marrow transplantation possible. By means of the invention, the time until the immune reconstitution is considerably shortened and the immune response after treatment are considerably reduced, in particular the occurrence of GvHD. The survival rate of the patient is considerably increased.

Abstract: The present invention provides an array for use in a method of monitoring T cell diversity. The array comprises a substrate having a plurality of capture probes that can specifically bind to a nucleic acid molecule corresponding to a T cell receptor (TCR) gene family selected from the group consisting of the TCR gene families listed in Table 1. In one format, the system has one or more oligonucleotide capture probes wherein each probe is selected from the group consisting of SEQ ID NO: 1-41. Further provided are methods for monitoring T cell diversity in a subject following, for example, allogeneic hematopoietic stem cell transplantation, or other treatment or therapy that contributes to an alteration in T cell population and/or diversity. Compositions of the invention include arrays, computer readable media, and kits for use in the methods of the invention.
