The present disclosure provides an allogeneic whole cell cancer vaccine platform that includes compositions and methods for treating and preventing cancer. Provided herein are compositions containing a therapeutically effective amount of cells from one or more cancer cell lines, some or all of which are modified to (i) inhibit or reduce expression of one or more immunosuppressive factors by the cells, and/or (ii) express or increase expression of one or more immunostimulatory factors by the cells, and/or (iii) express or increase expression of one or more tumor-associated antigens (TAAs), including TAAs that have been mutated, and which comprise cancer cell lines that natively express a heterogeneity of tumor associated antigens and/or neoantigens, and/or (iv) express one or more tumor fitness advantage mutations, including but not limited to acquired tyrosine kinase inhibitor (TKI) resistance mutations, EGFR activating mutations, and/or (v) express modified ALK intracellular domain(s), and/or express one or more driver mutations. Also provided herein are methods of making and preparing the vaccine compositions and methods of use thereof.

The present disclosure provides an allogeneic whole cell cancer vaccine platform that includes compositions and methods for treating and preventing colorectal cancer. Provided herein are compositions containing a therapeutically effective amount of cells from one or more cancer cell lines, some or all of which are modified to (i) inhibit or reduce expression of one or more immunosuppressive factors by the cells, and/or (ii) express or increase expression of one or more immunostimulatory factors by the cells, and/or (iii) express or increase expression of one or more tumor-associated antigens (TAAs), including TAAs that have been mutated, and which comprise cancer cell lines that natively express a heterogeneity of tumor associated antigens and/or neoantigens, and/or (iv) express one or more tumor fitness advantage mutations, including but not limited to driver mutations. Also provided herein are methods of making and preparing the colorectal cancer vaccine compositions and methods of use thereof.

The invention provides improved compositions for adoptive cell therapies for cancers that express the glycoepitope STn on TAG-72.

One aspect of this disclosure is directed to a method for treating a cancer in a subject in need thereof by administering to the subject at least a first compound and a second compound in any order together or separately. The first compound is an effective amount of a checkpoint inhibitor optionally with at least one pharmaceutically acceptable carrier. The second compound is an effective amount of an Therapeutic Double Stranded RNA (tdsRNA) optionally with at least one pharmaceutically acceptable carrier. The compounds can be administered together or separately. Compositions for the practice of the method are also described.

A polymeric nanoparticle is disclosed which comprises: (i) at least one disease-associated antigen which is capable of producing a T-cell response, wherein the disease-associated antigen is encapsulated in the nanoparticle; (ii) at least one adjuvant; and (iii) a dendritic cell targeting moiety which is attached to the outer surface of the nanoparticle.

Use of the nanoparticle for treating diseases associated with abnormal cell growth or an infection is also disclosed.

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.

Non-naturally occurring vesicles derived from bacteria, e.g., pathogenic bacteria, methods for making the vesicles, and methods for using compositions of these vesicles are disclosed. Methods of using the vesicles include prevention and/or treatment of bacterial infections. Also provided herein are compositions that include vesicles derived front bacteria and tumor vesicles, methods for making the tumor vesicles, and methods for using the compositions of bacterial vesicles and tumor vesicles. Methods of using the compositions of bacterial vesicles and tumor vesicles include treatment of cancer in a subject. Tumor vesicles may be derived from cancer cells present in the subject to be treated or from a cancer cell line expressing at least one neoantigen. The neoantigen may be specific to the subject and may have been identified by sequencing of the cancer cells from the subject. The neoantigen may be a neoantigen known to be commonly expressed in a particular type of cancer.

This disclosure relates to anti-TNFRSF9 (tumor necrosis factor receptor superfamily member 9) antibodies, antigen-binding fragments, and the uses thereof.

The present invention provides immune cells (such as CAR-T cells) having higher antitumor activity than immune cells (such as CAR-T cells) expressing a CAR alone (not expressing cytokines and/or chemokines). A T cell provided in one aspect of the present invention expresses (1) a chimeric antigen receptor (CAR), (2) at least one selected from the group consisting of interleukin-15 (IL-15), interleukin-18 (IL-18), interleukin-21 (IL-21), and interleukin-27 (IL-27), and (3) CC chemokine ligand 19 (CCL19).

The present invention relates to peptides, proteins, nucleic acids and cells for use in immunotherapeutic methods. In particular, the present invention relates to the immunotherapy of cancer. The present invention furthermore relates to tumor-associated T-cell peptide epitopes, alone or in combination with other tumor-associated peptides that can for example serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses, or to stimulate T cells ex vivo and transfer into patients. Peptides bound to molecules of the major histocompatibility complex (MHC), or peptides as such, can also be targets of antibodies, soluble T-cell receptors, and other binding molecules.
