Disclosed are immunotherapeutic compositions and the concurrent use of combinations of such compositions for the improved induction of therapeutic immune responses and/or for the prevention, amelioration and/or treatment of disease, including, but not limited to, cancer and infectious disease.

The invention provides compositions including stabilized multilamellar lipid vesicles having crosslinked lipid bilayers (referred to herein as interbilayer-crosslinked multilamellar vesicles or ICMV) and including an ALK variant, pharmaceutical compositions containing vesicles (e.g., ICMV) including an ALK variant, and methods of treatment using such compositions. The invention provides compositions including stabilized multilamellar lipid vesicles with crosslinked lipid bilayers (e.g., an interbilayer-crosslinked multilamellar vesicle or ICMV) containing an Anaplastic lymphoma kinase (ALK) variant as an antigen that is associated with solid tumor cancers.

Provided are polynucleotides and viral vectors, particularly, alphavirus vectors such as Sindbis viral vectors, which encode multiple, e.g., two or more, epitopes of at least one tumor associated antigen in which each epitope is separated by a processing or enzyme cleavage site. The multiple epitopes of the two or more tumor associated antigens encoded by the described polynucleotides and viral vectors may be the same or different. Methods of treating mammalian subjects having a cancer or tumor expressing the tumor associated antigen epitopes are provided, in which the viral vectors encoding the multiple epitopes, as well as other immunostimulatory or immunomodulatory components, generate an anti-cancer or anti-tumor immune response in which high levels of effector T cells increase the survivability of tumored mammalian subjects and result in epitope spreading, thus providing a further enhancement of the immune response.

A method of treating a patient who has hepatocellular carcinoma (HCC), colorectal carcinoma (CRC), glioblastoma (GB), gastric cancer (GC), esophageal cancer, NSCLC, pancreatic cancer (PC), renal cell carcinoma (RCC), benign prostate hyperplasia (BPH), prostate cancer (PCA), ovarian cancer (OC), melanoma, breast cancer (BRCA), CLL, Merkel cell carcinoma (MCC), SCLC, Non-Hodgkin lymphoma (NHL), AML, gallbladder cancer and cholangiocarcinoma (GBC, CCC), urinary bladder cancer (UBC), and uterine cancer (UEC) includes administering to said patient a composition containing a population of activated T cells that selectively recognize cells in the patient that aberrantly express a peptide. A pharmaceutical composition contains activated T cells that selectively recognize cells in a patient that aberrantly express a peptide, and a pharmaceutically acceptable carrier, in which the T cells bind to the peptide in a complex with an MHC class I molecule, and the composition is for treating the patient who has HCC, CRC, GB, GC, esophageal cancer, NSCLC, PC, RCC, BPH, PCA, OC, melanoma, BRCA, CLL, MCC, SCLC, NHL, AML, GBC, CCC, UBC, and/or UEC. A method of treating a patient who has HCC, CRC, GB, GC, esophageal cancer, NSCLC, PC, RCC, BPH, PCA, OC, melanoma, BRCA, CLL, MCC, SCLC, NHL, AML, GBC, CCC, UBC, and/or UEC includes administering to said patient a composition comprising a peptide in the form of a pharmaceutically acceptable salt, thereby inducing a T-cell response to the HCC, CRC, GB, GC, esophageal cancer, NSCLC, PC, RCC, BPH, PCA, OC, melanoma, BRCA, CLL, MCC, SCLC, NHL, AML, GBC, CCC, UBC, and/or UEC.

A composition comprising mesoporous silica rods comprising an immune cell recruitment compound and an immune cell activation compound, and optionally comprising an antigen such as a tumor lysate. The composition is used to elicit an immune response to a vaccine antigen.

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.

A set of target peptides are presented by HLA A*0101, A*0201, A*0301, B*4402, B*2705, B*1402, and B*0702 on the surface of disease cells. They are envisioned to among other things (a) stimulate an immune response to the proliferative disease, e.g., cancer, (b) to function as immunotherapeutics in adoptive T cell therapy or as a vaccine, (c) facilitate antibody recognition of tumor boundaries in surgical pathology samples, (d) act as biomarkers for early detection and/or diagnosis of the disease, and (e) act as targets in the generation antibody-like molecules which recognize the target-peptide/MHC complex.

Provided herein are isolated anaplastic lymphoma kinase (ALK) peptides that are fragments of the cytoplasmic portion of an ALK protein shared by cancers having an ALK rearrangement and cancers expressing the ALK protein, that bind a human leukocyte antigen (HLA), and elicit an immune response against one or more ALK-positive cancers. Also provided are isolated ALK peptides that are modified with an amphiphilic conjugate to increase T-cell expansion and greatly enhance anti-tumor efficacy. The invention also provides polynucleotides encoding isolated ALK peptides, vaccines comprising an isolated ALK peptide or polynucleotide, immunogenic compositions thereof, and kits for administering the same. Methods of treatment and methods of generating an immune response in a subject by administering the ALK-specific peptide antigens, immunogens, vaccines, or immunogenic compositions thereof are provided.
