Some embodiments of the methods and compositions provided herein include chimeric antigen receptors (CAR)s which specifically bind to an epitope of CD33, such as an epitope encoded by exon 2 of CD33. Some embodiments include the use of such CARs for effective and safe therapies for myeloid leukemias, such as acute myeloid leukemia and chronic myeloid leukemia.

The present disclosure relates to methods of treating diseases or disorders associated with LGL and/or NK cells, methods of reducing or depleting LGL and/or NK cells, and methods of inducing ADCC activity using antibodies that bind to a cell surface protein on LGL and/or NK cells and comprise enhanced ADCC activity. The present invention also relates to a method of depleting or reducing the numbers of large granular lymphocytes and natural killer cells in a human subject upon administration of CD94 or CD57 or NKG2A binding molecule that consists of a part that specifically binds to the CD94 or CD57 or NKG2A receptors and an immunoglobulin Fc part. In a specific embodiment, a method of the invention depletes or reduces the number of large granular lymphocytes and natural killer cells in spleen, blood, bone marrow, joints, or other tissues.

The present disclosure relates to methods for improving the safety profile of adoptive cell transfer therapies. In particular, the present disclosure relates to methods for improving the safety profile of CAR T-cell therapies. Disclosed is an anti-CD25 antibody-drug-conjugate for use in a method of treatment or prevention of CAR immune cell toxicity in an individual.

The present invention provides an immune enhancer comprising at least an interferon and a granulocyte-macrophage colony-stimulating factor, and an immunotherapeutic pharmaceutical composition comprising at least an antigen and the above-mentioned immune enhancers. The present invention further discloses a preparation method of the immunotherapeutic pharmaceutical composition, the use of the immune enhancer and the immunotherapeutic pharmaceutical composition. The immune enhancer can be applied to disease and tumor treatments caused by viruses, bacteria, and other microorganisms.

Novel therapeutic immunotherapy compositions comprising at least two vectors, each vector encoding a functional CAR, whereby the combination of vectors results in the expression of two or more non-identical binding domains, wherein each vector encoded binding domain(s) are covalently linked to a transmembrane domain and one or more non-identical intracellular signaling motifs are provided herein as well as are methods of use of same in a patient-specific immunotherapy that can be used to treat cancers and other diseases and conditions.

Methods of increasing or enhancing the efficacy of CAR B cell malignancy treatment regimens using immune effector cells (e.g., T cells, NK cells, CIK cells, macrophages) engineered to express chimeric antigen receptors (CAR(s)) that target malignant B cells in combination with antibodies (e.g., monoclonal antibodies, antibody-drug conjugates) that target malignant B cells are provided. Also provided are methods of treating a B cell malignancy in a subject comprising administering to the subject a CAR B cell malignancy treatment regimen and an antibody that targets malignant B cells.

Provided herein, inter alia, nucleic acids including coding sequences for human CD80, IL-15, IL-15Rα polypeptides, wherein the coding sequence for hCD80 is operably positioned upstream to the coding sequences for hIL-15 and hIL-15Rα. The disclosure also provides recombinant cells, cell cultures, pharmaceutical compositions, and whole-cell vaccines containing the recombinant cells disclosed herein. Also disclosed are methods useful for treating myeloma and leukemias, such as acute myelogenous leukemia (AML).

Provided is an immune cell therapy which uses an iPS technology allowing long-term survival in a living body and which exhibits an excellent antitumor effect by recognition of two antigens.

An iPS cell derived from an antigen-specific cytotoxic T cell having a chimeric antigen receptor introduced therein.

The present invention relates to a hydroxyapatite and/or tricalcium phosphate powder characterized in that it has undergone at least one sintering step at a temperature between 400° C. and 600° C. The invention also relates to a process for preparing such a powder, and to a composition comprising such a powder for use as an anti-tumour auto-vaccine and particularly in the treatment of the following pathological conditions: osteosarcoma, B or T lymphoma, mammary tumour, melanoma, haemangiosarcoma, mastocytoma, fibrosarcoma, brain tumours and schwannoma in a subject. The present invention also covers a drug combination comprising the composition of the invention and at least one second therapeutic agent, preferably an anti-tumour agent and/or a radiotherapeutic agent.

A genetically modified cytotoxic T cell includes one or more exogenous nucleic acid molecules encoding a transgenic antigen-targeting construct. Estrogen receptor-binding fragment-associated antigen 9 (EBAG9) activity is inhibited in the cells. The antigen-targeting construct can be a chimeric antigen receptor (CAR) or T cell receptor (TCR). The modified T cell can be used in the treatment of a proliferative disease, in particular for the treatment of hematologic malignancies. A pharmaceutical composition includes the modified T cell, a nucleic acid vector encoding the antigen-targeting construct and an inhibitor of EBAG9, such an RNA interference molecule. An in vitro method can increase the cytolytic activity of a cytotoxic T cell.
