Abstract: The concurrent administration of chemotherapy and immunotherapy has been considered a contraindication because of the concern that the induced lymphopenia would ablate therapeutic efficacy of immunotherapy. Temozolomide has been shown to be an effective chemotherapeutic for patients with malignant gliomas and to deprive patients with glioblastoma (GBM) patients of this agent in order to treat with immunotherapy is controversial. Despite conventional dogma, we demonstrate that both chemotherapy and immunotherapy can be delivered concurrently without negating the effects of immunotherapy. In fact, the temozolomide induced lymphopenia may actually be synergistic with a peptide vaccine.

Abstract: The present invention relates to compositions, methods, and kits for eliciting an immune response to at least one CMV antigen expressed by a cancer cell, in particular for treating and preventing cancer. CMV determination methods, compositions, and kits also are provided.

Abstract: Detection of human antibodies directed against the tumor-specific protein Epidermal Growth Factor Receptor variant Class III (EGFRvIII) provide information on tumor burden and vaccine response. The methods of the invention permit the specific identification of antibodies that are able to bind to EGFRvIII. The methods are useful in determining the presence of an EGFRvIII-expressing tumor and in detecting immune responses following immunization with EGFRvIII-derived peptide as part of a cancer immunotherapy regimen.

Abstract: Cancers and other diseases can be treated with two or three types of agents: an agent which induces lymphodepletion or lymphopenia; an inhibitory antibody to a surface marker on Treg cells; and optionally a specific antigen. This combination may lead to enhanced immune responses despite lymphodepletion or lymphopenia.

Abstract: We have constructed bispecific antibody engaging molecules which have one arm that specifically engages a tumor cell which expresses the human EGFRvIII mutant protein on its surface, and a second arm that specifically engages T cell activation ligand CD3. The engaging molecules are highly cytotoxic and antigen-specific. These are promising therapeutic agents.

Abstract: Cancers are treated with three types of agents: a chemotherapeutic agent which induces lymphopenia; an inhibitory antibody to a surface marker on Treg cells; and an anti-cancer vaccine. This combination may lead to enhanced immune responses despite lymphodepletion.

Abstract: Vaccination with an allogeneic cell line modified with genetic material encoding specific protein antigens is an effective technique for the delivery of protein antigens to the host's antigen presentation system. The immune response generated by this vaccine is restricted by the major histocompatibility complex type of the host and not the vaccinating cell line. This immunization strategy may be used to treat or prevent tumors or infectious diseases of a mammal.
