Disclosed herein are compositions and methods of use comprising combinations of anti-CD22 antibodies with a therapeutic agent. The therapeutic agent may be attached to the anti-CD22 antibody or may be separately administered, either before, simultaneously with or after the anti-CD22 antibody. In preferred embodiments, the therapeutic agent is an antibody or fragment thereof that binds to an antigen different from CD22, such as CD19, CD20, CD21, CD22, CD23, CD37, CD40, CD40L, CD52, CD80 and HLA-DR. However, the therapeutic agent may an immunomodulator, a cytokine, a toxin or other therapeutic agent known in the art. More preferably, the anti-CD22 antibody is part of a DNL complex, such as a hexavalent DNL complex. Most preferably, combination therapy with the anti-CD22 antibody or fragment and the therapeutic agent is more effective than the antibody alone, the therapeutic agent alone, or the combination of anti-CD22 antibody and therapeutic agent that are not conjugated to each other. Administration of the anti-CD22 antibody and therapeutic agent induces apoptosis and cell death of target cells in diseases such as B-cell lymphomas or leukemias, autoimmune disease or immune dysfunction disease.

A chimeric LL2 monoclonal antibody is described in which the complementarity determining regions (CDRs) of the light and heavy chains of the murine LL2 anti-B-lymphoma, anti-leukemia cell monoclona lantibody has been recombinantly joined to the human kappa and IgG₁ constant region domains, respectively, which retains the immunospecificity and B-cell lymphoma and leukemia cell internalization capacity of the parental murine LL2 monoclonal antibody, and which has the potential of exhibiting reduced human anti-mouse antibody production activity. A humanized LL2 monoclonal antibody is described in which the CDRs of the light and heavy chains have been recombinantly joined to a framework sequence of human light and heavy chains variable regions, respectively, and subsequently linked to human kappa and IgG₁ constant region domains, respectively, which retains the immunospecificity and B-lymphoma and leukemia cell internalization capacities of the parental murine and chimeric LL2 monoclonal antibodies, and which has the potential for exhibiting reduced human anti-mouse antibody production activity. Vectors for producing recombinant chimeric and humanized chimeric monoclonal antibodies are provided. Isolated DNAs encoding the amino acid sequences of the LL2 variable light and heavy chain and CDR framework regions are described.

The invention is directed to a method of prognosing in an individual a transformation from follicular lymphoma to diffuse large B-cell lymphoma (DLBCL) by measuring changes and/or lack of changes in certain groups of related clonotypes, referred to herein as “clans,” in successive clonotype profiles of the individual. A clan may arise from a single lymphocyte progenitor that gives rise to many related lymphocyte progeny, each possessing and/or expressing a slightly different immunoglobulin receptor due to somatic mutation(s), such as base substitutions, inversions, related rearrangements resulting in common V(D)J gene segment usage, or the like. A higher likelihood of transformation from follicular lymphoma to DLBCL is correlated with the persistence of clans in successive clonotype profiles whose clonotype membership fails to undergo diversification over time.

The present invention relates to the recombinant method used for the production of soluble form of an antibody that binds to CD20 for treatment of patients with relapsed or refractory, low-grade or follicular, CD20-positive, B-cell non-Hodgkin's lymphoma (NHL). The treatment will comprise the use of immunologically active anti-CD20 antibodies; or radiolabeled anti-CD20 antibodies and or cooperative strategies where both labeled and non-labeled antibodies will be used for treatment of NHL. The procedure describes the de novo synthesis of the nucleic acid sequence encoding anti-CD20, transformation of the constructed nucleic acid sequences into competent bacteria and the sub-cloning of the same into mammalian expression vectors for expression of the desired protein. DNA constructs comprising the control elements associated with the gene of interest has been disclosed. The nucleic acid sequence of interest has been codon optimized to permit expression in the suitable mammalian host cells.
