The present disclosure provides combinations of immunotherapeutics and methods for treating medical conditions that are characterized by the lack of an effective immune response, for example as would result following a down-regulation of MHC class I, such as in cancer. The immunotherapeutic compositions of the invention, which can be used to treat the medical conditions, include one or more immunostimulatory antibodies or molecules having specificity for CTLA-4, PD-1, PD-L1, PD-L2, CD40, OX40, CD137, GITR, ILT2, or ILT3, or ligands for these molecules (e.g., an isolated fully-human monoclonal antibody) in association with one or more alloantigens, such as, vector(s) capable of expressing protein(s) or peptide(s) that stimulate T-cell immunity against tissues or cells, formulated in a pharmaceutically acceptable carrier. The proteins or peptides may comprise class I major histocompatibility complex (MHC) antigens, β2-microglobulins, or cytokines. The MHC antigen may be foreign to the subject. The MHC antigen may be HLA-B7.

Nanoparticles that activate complement in the absence of biological molecules are described. The nanoparticles are shown to specifically target antigen presenting cells in specifically in lymph nodes, without the use of a biological molecule for targeting. These particles are useful vehicles for delivering immunotherapeutics. Surface chemistries and chemical formulations for the nanoparticles are described.

The present invention provides isolated monoclonal antibodies, particularly human monoclonal antibodies, that specifically bind to PD-1 with high affinity. Nucleic acid molecules encoding the antibodies of the invention, expression vectors, host cells and methods for expressing the antibodies of the invention are also provided. Immunoconjugates, bispecific molecules and pharmaceutical compositions comprising the antibodies of the invention are also provided. The invention also provides methods for detecting PD-1, as well as methods for treating various diseases, including cancer and infectious diseases, using anti-PD-1 antibodies. The present invention further provides methods for using a combination immunotherapy, such as the combination of anti-CTLA-4 and anti-PD-1 antibodies, to treat hyperproliferative disease, such as cancer. The invention also provides methods for altering adverse events related to treatment with such antibodies individually.

The present invention relates to stress proteins and methods of modulating an individual's immune response. In particular, it relates to the use of such stress proteins in immune therapy and prophylaxis, which results in an induction or enhancement of an individual's immune response and as an immunotherapeutic agent which results in a decrease of an individual's immune response to his or her own cells. The present invention also relates to compositions comprising a stress protein joined to another component, such as a fusion protein in which a stress protein is fused to an antigen. Further, the present invention relates to a method of generating antibodies to a substance using a conjugate comprised of a stress protein joined to the substance.

An adjuvant complex composed of bacterial outer membrane protein proteosomes complexed to bacterial liposaccharide is prepared to contain the component parts under a variety of conditions. The complex can be formulated with antigenic material to form immunogenic compositions, vaccines and immunotherapeutics. An induced immune response includes protective antibodies and/or type 1 cytokines is shown for a variety of protocols.

The present invention is directed to pharmaceutical methods for the treatment of CD30 positive diseases, such as Hodgkin's disease, by administration of a combination of at least one sheddase inhibitor and at least one anti-CD30 immunotherapeutic.

Described herein are modified immunotherapeutic agents including a first monoclonal antibody covalently linked to a second monoclonal antibody generating a single new immunotherapeutic agent. The first and second monoclonal antibodies stimulate different anti-tumor pathways. Advantageously, the modified single immunotherapeutic agent is capable of activating both anti-tumor pathways. Also included herein are methods of treating cancer with the modified immunotherapeutic agents.

Disclosed herein are methods for matching a cancer condition with an appropriate immunotherapeutic agent and/or regimen. Also disclosed are methods for confirming diagnosis of a particular type of cancer. Embodiments of the invention disclosed herein are directed to the use of effective combinations of TuAAs to optimize the match between a patient's cancer condition and available immunotherapies.

The present invention relates to receptors for heat shock proteins (HSPs), such as gp96, Hsp70 and Hsp90. The heat shock receptor is associated with the cell membranes of a subset of antigen presenting cells, such as macrophages and dendritic cells. The present invention relates to the use of the heat shock protein receptor positive cells, heat shock protein receptor protein, and heat shock protein receptor genes in methods for screening a molecule for the ability to modulate heat shock protein levels or activities.

The invention provides methods for determining effective immunotherapeutic agents which may be used for the treatment of cognitive disorders.

Compositions, recombinant vaccines and live attenuated pathogens comprising one or more isolated nucleic acid molecules that encode an immunogen in combination with an isolated nucleic acid molecule that encodes IL-28 or a functional fragment thereof are disclosed. Methods of inducing an immune response in an individual against an immunogen, using such compositions are disclosed.

Described herein are methods of using compounds that inhibit leukemia inhibitory factor (LIF) and/or block of the leukemia inhibitory factor receptor for treatment of liver fibrosis, proliferation of spinal tumors, and in combination therapy with an immunotherapeutic agent.

The invention relates to a product comprised of specific combinations of cell lines intended for use as an allogeneic immunotherapy agent for the treatment of prostate cancer in humans. The heterogeneity of the immunotherapeutic matches the heterogeneity of the antigenic profile in the target prostate cancer and immunises the recipients with many of the potential TAA and TSA which are expressed at various stages of the disease. The invention discloses a vaccine comprising a combination of three different cell lines prepared from primary or metastatic prostate cancer biopsy material. The cell lines are lethally irradiated utilising gamma irradiation at 50-300 Gy to ensure that they are replication incompetent.

Improved vaccines which include a nucleotide sequence that encodes immunomodulating protein operably linked to regulatory elements are disclosed. The improved vaccines include DNA vaccines, recombinant vaccines for delivering foreign antigen and live attenuated vaccines. Methods of immunizing individuals are disclosed. Compositions for and methods of treating individuals with autoimmune diseases are disclosed.

Metal-organic frameworks (MOFs) comprising photosensitizers are described. The MOFs can also include moieties capable of absorbing X- rays and/or scintillation. Optionally, the photosensitizer or a derivative thereof can form a bridging ligand of the MOF. Further optionally, the MOF can comprise inorganic nanoparticles in the cavities or channels of the MOF or can be used in combination with an inorganic nanoparticle. Also described are methods of using MOFs and/or inorganic nanoparticles in photodynamic therapy or in X-ray induced photodynamic therapy, either with or without the co-administration of one or more immunotherapeutic agent and/or one or more chemotherapeutic agent.

Nucleic acid molecules that encode IL-15 or fragments thereof, which express protein at a higher level than nucleic acid molecules with native coding sequences for IL-15 are disclosed. Nucleic acid molecules with additional modifications such as the absence of coding sequences for IL-15 signal sequences and/or the absence of IL-15 untranslated sequences and/or inclusion of non-IL-15 signal sequences are also disclosed. Vectors, including plasmids and viral vectors, comprising such nucleic acid molecules; and to host cells comprising such nucleic acid molecules are disclosed as well as methods of using such nucleic acid molecules alone or in combination with nucleic acid sequences encoding immunogens which are part of the nucleic acid molecules and/or part of a different nucleic acid molecule. Recombinant vaccines and live attenuated pathogens encoding fusion proteins, and methods of using the same, are disclosed.
