Abstract:
Predictive biomarkers identify those patients suffering from immunoglobulin positive (lg+) B lineage malignancies that are responsive to active immunotherapy, where the active immunotherapy comprises vaccination with a tumor-specific idiotype-immunogen. It is shown herein that patient responsiveness to the idiotype-immunogen is dependent upon the sequence of the immunogen, where an immunogen having a low number of tyrosine residues in the CDR1 (herein termed CDR1 -Y10) regions of one or both of the immunogen heavy and light chains is predictive of a positive anti-tumor response, while a high number of CDR1 tyrosine residues (herein termed CDR1 -Yhi) is predictive of a low anti tumor response.

Abstract:
Immunocomplexes which consist essentially of a B cell lymphoma tumor-associated antigen or a fragment thereof containing an epitope characteristic of the tumor and an immune-enhancing cytokine such as GM-CSF, IL-2 or IL-4 elicit immune responses which are protective with respect to tumor proliferation. Antibodies immunoreactive with these immunocomplexes are also useful as passive vaccines and as analytical tools.
Abstract:
Methods of enhancing the efficacy of antibody-directed cellular cytotoxicity (ADCC) for therapy directed to killing of tumor cells are disclosed. Cancer specific cell surface antigens are bound by monoclonal antibodies, thereby stimulating a cytotoxic T cell response characterized by an upregulation of cell surface expression of costimulatory molecules on the T cell. The ADCC response is augmented by the subsequent administration of a second antibody that is an agonist of the costimulatory molecule.
Abstract:
There are provided herein, inter alia, complexes, compositions and methods for the delivery of therapeutic, diagnostic and imaging agents, including nucleic acid, into a cell. The complexes, compositions and methods may facilitate complexation, protection, delivery and release of oligonucleotides and polyanionic cargos into target cells, tissues, and organs both in vitro and in vivo.
Abstract:
Predictive biomarkers identify those patients suffering from immunoglobulin positive (lg + ) B lineage malignancies that are responsive to active immunotherapy, where the active immunotherapy comprises vaccination with a tumor-specific idiotype-immunogen. It is shown herein that patient responsiveness to the idiotype-immunogen is dependent upon the sequence of the immunogen, where an immunogen having a low number of tyrosine residues in the CDR1 (herein termed CDR1 -Y 10 ) regions of one or both of the immunogen heavy and light chains is predictive of a positive anti-tumor response, while a high number of CDR1 tyrosine residues (herein termed CDR1 -Y hi ) is predictive of a low anti tumor response.
Abstract:
Methods and kits for classifying patients having diffuse large B-cell lymphoma (DLBCL) based upon expression of a plurality of genes are disclosed. Real-time quantitative RT-PCR can be used to measure expression values. Correlating expression values of the plurality of genes in a tumor sample from the patient to reference expression values obtained from DLBCL patients can stratify patients in the classification groups. The methods and kits can be used to predict overall patient survival.
