The present disclosure relates to compositions and methods for enhancing T cell response and/or CAR cell expansion and/or maintenance in vivo and/or in vitro. For example, a method of enhancing T cell-based therapy comprises administering a mixed population of T cells comprising modified T cells comprising a first chimeric antigen receptor (CAR) and modified T cells comprising a second CAR, wherein a binding domain of the first CAR binds a first antigen, and a binding domain of the second CAR binds a second antigen. The first antigen is different from the second antigen. In embodiments, the first CAR binds a surface molecule or antigen of a white blood cell.

Provided herein are immunogenic compositions comprising a recombinant modified vaccinia virus Ankara (MVA) comprising a nucleic acid sequence encoding a CD40 ligand (CD4OL) and a nucleic acid sequence encoding a heterologous disease-associated antigen, wherein the immunogenic composition induces increases T-cell immune responses specific for the heterologous disease-associated antigen when administered to a human host, and related methods and uses.

Provided are methods for enhancing anti-tumor and/or anti-cancer immunotherapies. In some embodiments, the methods include administering to a subject in need thereof a composition that includes a conjugate that includes a gastrin immunogen conjugated to an immunogenic carrier, optionally conjugated via a linker, in an amount and via a route sufficient to enhance entry into the tumor and/or cancer of an anti-tumor T cell, whereby an anti- and/or anti-cancer tumor immunotherapy is enhanced. Also provided are pharmaceutical compositions that have the conjugates for use in treating tumors and cancers, methods for treating tumors and/or cancers, and methods for sensitizing solid tumors and/or cancers in subjects to chimeric antigen receptor-T (CAR-T) cell therapies.

Provided are methods for preventing initiation and/or progression of gastrin-associated tumors and/or cancers in subjects. In some embodiments, the methods relate to administering compositions that gastrin immunogens to subjects. Also provided are methods for inhibiting development of gastrin-associated precancerous lesions, methods for preventing formation of fibrosis associated with a tumor and/or a cancer, uses of compositions that include a gastrin immunogen to prevent initiation and/or development of a gastrin-associated tumor or cancer and/or for preparing medicaments therefor, and compositions for use in preventing initiation and/or development of gastrin-associated tumors and/or cancers and/or precancerous lesions thereof.

Described herein is a method of preventing or treating a disease in a mammalian subject, comprising administering to the subject who is in need thereof an effective dosage of a pharmaceutical composition comprising a virus like particle (VLP) comprising: an alphavirus replicon comprising a recombinant polynucleotide, wherein the polynucleotide comprises a sequence encoding both subunits of a human class II major histocompatibility antigen, a retroviral gag protein, and a fusogenic envelope protein, wherein the VLP does not contain an alphavirus structural protein gene.

Provided herein are immunogenic compositions comprising a recombinant modified vaccinia virus Ankara (MVA) comprising a nucleic acid sequence encoding a CD40 ligand (CD40L) and a nucleic acid sequence encoding a heterologous disease-associated antigen, wherein the immunogenic composition induces increases T-cell immune responses specific for the heterologous disease-associated antigen when administered to a human host, and related methods and uses.

The present invention relates to immunogens directed against lung cancer associated proliferative peptides and growth factors and its uses thereof in conjunction with chemotherapeutics in the early and advanced treatment of various malignant diseases, especially including lung cancers, both small cell lung carcinomas (SCLC), non-small cell lung (NSCLC) cancers and neuroendocrine-type cancers.

An anti-adrenomedullin (ADM) antibody or an anti-adrenomedullin antibody fragment or an anti-ADM non-Ig scaffold, pharmaceutical compositions containing them and uses therefor.

This invention describes ways of obtaining nano-particulated adjuvants formed by different synthetic variants of GM3 ganglioside. Depending on the fine structure of the fatty acid in the ceramide of the synthetic GM3, said adjuvants are able to stimulate specifically and in a specialized way the humoral or cellular immune response against accompanying antigens. Particularly, this invention provides immunogenic vaccine compositions that comprise peptides, polypeptides or proteins and the aforementioned nanoparticles, which are formed through the dispersion of hydrophobic proteins of the outer membrane complex (OMC) of Neisseria meningitidis in solutions containing fully synthetic variants of the GM3 ganglioside.

This invention relates to methods and materials for nucleic acid delivery, vaccination, and/or treating cancer. More specifically, methods and materials for nucleic acid delivery, vaccination, and/or treating cancer using one or more recombinant adenoviruses (Ads) as an oncolytic agent are provided.
