Immunotherapies employing self-assembling vaccines

Abstract

Provided herein are self-assembling pharmaceutical compositions comprising a heat shock protein fused to a biotin-binding protein, wherein the biotin-binding protein is non-covalently bound to four biotinylated components, and further wherein at least two of the four biotinylated components are not identical.

1 - 26 . (canceled) 
     
     
         27 . A method of preventing or treating cancer in a subject, comprising administering to the subject a pharmaceutical composition comprising a heat shock protein fused to a biotin-binding protein, wherein the biotin-binding protein is non-covalently bound to a biotinylated tumor antigen. 
     
     
         28 . The method of  claim 27 , wherein the biotin-binding protein is selected from avidin, streptavidin, and neutravidin. 
     
     
         29 . The method of  claim 27 , wherein the biotin-binding protein has an amino acid sequence that is at least 80%, 85%, 90%, 95%, or 99% identical to the avidin sequence of NCBI Accession No. NP_990651 or the streptavidin sequence of NCBI Accession No. AAU48617. 
     
     
         30 . The method of  claim 27 , wherein the heat shock protein is a mammalian heat shock protein or a bacterial heat shock protein. 
     
     
         31 . The method of  claim 27 , wherein the heat shock protein is a member of the heat shock protein 70 (hsp70) family. 
     
     
         32 . The method of  claim 27 , wherein the heat shock protein is or is derived from  Mycobacterium tuberculosis  (MTb) HSP 70. 
     
     
         33 . The method of  claim 27 , wherein the heat shock protein has an amino acid sequence that is at least 80%, 85%, 90%, 95%, or 99% identical to SEQ ID NO: 1 or SEQ ID NO: 2. 
     
     
         34 . The method of  claim 27 , wherein the pharmaceutical composition further comprises a pharmaceutically acceptable carrier. 
     
     
         35 . The method of  claim 27 , wherein the tumor antigen is derived from a sarcoma cell or a carcinoma cell. 
     
     
         36 . The method of  claim 27 , wherein the tumor antigen is derived from a fibrosarcoma, myxosarcoma, liposarcoma, chondrosarcoma, osteogenic sarcoma, chordoma, angiosarcoma, endotheliosarcoma, lymphangiosarcoma, lymphangioendotheliosarcoma, synovioma, mesothelioma, Ewings tumor, leiomyosarcoma, rhabdomyosarcoma, colon carcinoma, colorectal cancer, pancreatic cancer, breast cancer, ovarian cancer, prostate cancer, squamous cell carcinoma, basal cell carcinoma, adenocarcinoma, Sweat gland carcinoma, sebaceous gland carcinoma, papillary carcinoma, papillary adenocarcinomas, cystadenocarcinoma, medullary carcinoma, bronchogenic carcinoma, renal cell carcinoma, hepatoma, bile duct carcinoma, choriocarcinoma, seminoma, embryonal carcinoma, Wilms tumor, cervical cancer, testicular tumor, lung carcinoma, Small cell lung carcinoma, bladder carcinoma, epithelial carcinoma, glioma, astrocytoma, medulloblastoma, cranio pharyngioma, ependymoma, pinealoma, hemangioblastoma, acoustic neuroma, oligodendroglioma, meningioma, melanoma, neuroblastoma, retinoblastoma, leukemias, polycythemia Vera, lymphoma, multiple myeloma, Waldenstrom’s macroglobulinemia, or heavy chain disease cell. 
     
     
         37 . The method of  claim 27 , wherein the tumor antigen is derived from an ovarian cancer cell. 
     
     
         38 . The method of  claim 27 , wherein the tumor antigen is derived from a cervical cancer cell. 
     
     
         39 . The method of  claim 27 , wherein the biotinylated tumor antigen is derived from the same type of cancer as the cancer to be prevented or treated. 
     
     
         40 . A method of inducing an immune response in a subject, comprising administering to the subject a pharmaceutical composition comprising a heat shock protein fused to a biotin-binding protein, wherein the biotin-binding protein is non-covalently bound to a biotinylated tumor antigen.
