Combination therapeutics for the treatment of cancer include the use of immune effector cells, IL-15 based superagonists and one or more immunotherapeutic agents such as Bacillus Calmette-Guerin (BCG).

Provided are a genetically modified immune cell, a preparation method therefor, and an application. The immune cell overexpresses HIL-6 and/or L-GP130. HIL-6 or L-GP130 continuous overexpression/conditionally induced overexpression in the immune cell reduces the side effects of CAR-T therapy while maintaining immune and anti-tumour effects, and has potential value in the treatment of malignant tumours and AIDS.

The present invention concerns methods and compositions for immunotherapy employing a modified T cell comprising disrupted T cell receptor and/or HLA and comprising a chimeric antigen receptor. In certain embodiments, the compositions are employed allogeneically as universal reagents for “off-the-shelf” treatment of medical conditions such as cancer, autoimmunity, and infection. In particular embodiments, the T cell receptor-negative and/or HLA-negative T cells are generated using zinc finger nucleases, for example.

The present invention provides immunoresponsive cells, including T cells, cytotoxic T cells, regulatory T cells, and Natural Killer (NK) cells, expressing an antigen recognizing receptor and an inhibitory chimeric antigen receptor (iCAR). Methods of using the immunoresponsive cell include those for the treatment of neoplasia and other pathologies where an increase in an antigen-specific immune response is desired.

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).

The present invention provides a complex for use in the prevention and/or treatment of cancer, the complex comprising a) a cell penetrating peptide, b) at least one antigen or antigenic epitope, and c) at least one TLR peptide agonist, wherein the components a)-c) are covalently linked. In particular, compositions for use in the prevention and/or treatment of cancer, such as a pharmaceutical compositions and vaccines are provided.

Provided herein are methods for delaying or inhibiting T cell maturation or differentiation in vitro for a T cell therapy, comprising contacting one or more T cells from a subject in need of a T cell therapy with an AKT inhibitor and at least one of exogenous Interleukin-7 (IL-7) and exogenous Interleukin-15 (IL-15), wherein the resulting T cells exhibit delayed maturation or differentiation. In some embodiments, the method further comprises administering the one or more T cells to a subject in need of a T cell therapy.

The present invention provides immunoresponsive cells, including T cells, cytotoxic T cells, regulatory T cells, and Natural Killer (NK) cells, expressing at least one of an antigen recognizing receptor and one of a chimeric costimulatory receptor. Methods of using the immunoresponsive cell include those for the treatment of neoplasia and other pathologies where an increase in an antigen-specific immune response is desired.

Provided herein are interleukin-13 receptor α2 peptide-based brain cancer vaccines and methods for treating and vaccinating against brain cancer comprising administering to patients in need thereof interleukin-13 receptor α2 peptide-based brain cancer vaccines. Also provided herein are regimens comprising interleukin-13 receptor α2 peptides and at least one additional peptide and/or immunostimulant.
