Disclosed are vaccines and vaccine adjuvants useful in the treatment and/or prevention of infection and diseases associated with infectious pathogens, such as tetanus, as well as diseases associated with biological toxins. Also provided are methods of preparing an adjuvant and the vaccine containing the adjuvant. Methods are also provided for vaccinating/immunizing an animal against infection and diseases associated with infectious pathogens, such as tetanus, and other diseases associated with biological toxins. Adjuvant materials are presented that are prepared from an extracellular matrix material. The adjuvants are demonstrated to enhance the immunogencity of an infectious pathogen antigen or biological toxin antigen of interest, as well as to enhance the survival of an immunized animal.

Extracellular matrix materials as vaccine adjuvants for diseases associated with infectious pathogens or toxins

Disclosed are compositions and pharmaceutical preparations suitable for inhibiting metastasis of a malignant cancer in an animal. Methods for inhibiting and/or eliminating metastasis in an animal are also provided. In some embodiments, the preparations and compositions comprise a whole cell tumor preparation comprising tumor tissue cells and tumor connective tissue stroma. The disclosure also provides methods for preparing the preparations and pharmaceutical preparations. Inhibition of metastasis of malignant prostate cancer to the lung is shown in vivo.

Metastasis inhibition preparations and methods

Disclosed are vaccines and vaccine adjuvants useful in the treatment and/or prevention of infection and diseases associated with infectious pathogens, such as tetanus, as well as diseases associated with biological toxins. Also provided are methods of preparing an adjuvant and the vaccine containing the adjuvant. Methods are also provided for vaccinating/immunizing an animal against infection and diseases associated with infectious pathogens, such as tetanus, and other diseases associated with biological toxins. Adjuvant materials are presented that are prepared from an extracellular matrix material. The adjuvant may also be described as a heterologous acellular collagenous tissue preparation. The adjuvants are demonstrated to enhance the immunogencity of an infectious pathogen antigen or biological toxin antigen of interest, as well as to enhance the survival of an immunized animal.

Compositions suitable for use as ovarian cancer and/or tumor adjuvants in the preparation of ovarian cancer vaccines, particularly those vaccines useful in the treatment of human ovarian cancer, are provided. The ovarian cancer adjuvants described are comprised of an extracellular matrix material, such as small intestinal submucosal (SIS) tissue. The preparations may take the form of sheets, gels, liquids (injectable), tracer, or other solid or semi-solid preparation. Also disclosed are ovarian tumor inhibiting compositions that include extracellular matrix tissue adjuvants.

Extracellular matrix adjuvant and methods for prevention and/or inhibition of ovarian tumors and ovarian cancer

Disclosed are mammalian tumor and/or cancer cell conditioned substrate preparations having tumor inhibiting activity. In some embodiments, the mammalian tumor and/or cancer cell conditioned substrate preparations are essentially free of cellular components. These preparations comprise a conditioned heterologous acellular collagenous tissue preparation, and may be prepared using a mammalian extracellular matrix substrate. The conditioned substrates include many different anti-tumor and/or anti-cancer biomolecules, such as that population of anti-tumor biomolecules that are secreted and/or produced by mammalian tumor and/or cancer cells as they grow on a substrate, thus imparting the anti-tumor and/or anti-cancer properties to the conditioned substrates of the invention. The present disclosure also provides methods for preparing the mammalian tumor and/or cancer cell conditioned substrates, as well as methods for using the preparations to inhibit tumor growth, such as in a vaccine or wound dressing. Methods for inhibiting prostate tumors and melanoma with the described conditioned substrates are also described. The conditioned mammalian tumor and/or cancer cell substrate preparations are essentially free of viable and/or carcinogenic or invasive tumor and/or cancer cells. The conditioned substrates and substrate preparations include anti-tumor and anti-cancer properties that may be used in preparations and formulations for the treatment of cancer.

Anti-tumor/cancer heterologous acellular collagenous preparations and uses thereof

Compositions suitable for use as adjuvants in the preparation of vaccines, particularly those vaccines useful in the treatment of cancer, are provided. Methods for inhibiting tumor growth in an animal are also disclosed. Methods for immunizing an animal against cancer, such as prostate cancer, are also described. The adjuvants described are comprised of an extracellular matrix material, such as small intestinal submucosal (SIS) tissue. The preparations may take the form of sheets, gels, liquids (injectable), trocar, or other solid or semi-solid preparation. The invention provides for enhanced tumor inhibition of 2-fold or greater, compared to vaccine preparations without the extracellular matrix material, or from 4- to 5-fold, compared to preparations without the adjuvant promoting extracellular materials.

Extracellular matrix cancer vaccine adjuvant

Compositions comprising a tissue vaccine that include a mixture of heterogeneous tissue obtained from tumors and connective tissues. Vaccines comprising these compositions are also provided, as well as methods of using the vaccines in the treatment and/or inhibition of tumor growth, and particularly prostate tumor growth and cancers. The preparations may be defined as vaccines comprising tumor cells and connective (stromal) tissues derived from xenogeneic animals. Preparations comprising the tissue vaccines are provided using tissue harvested directly from tumors. Methods for preventing de novo development of cancer are also disclosed. A tissue vaccine comprising glutaraldehyde-(GFT) treated tissue prepared from tumor and connective tissue reduces the incidence of autochthonous prostate cancer. A tissue vaccine comprising a potassium thiocyanate extract (PTE) preparation of a tumor and connective tissue is also provided. The tissue vaccines are demonstrated to reduce the incidence of autochthonous prostate cancer.
