  • the invention relates to compositions, methods, processes, kits and devices for the design, preparation, manufacture and/or formulation of antibodies in vivo.
  • Antibodies also known as immunoglobulins, are glycoproteins produced by B cells. Using a unique and highly evolved system of recognition, antibodies can recognize a target and tag a target epitope, foreign entity or invading microbe for attack by the immune system thereby neutralizing its effect. The production of antibodies is the main function of the humoral immune system. Antibodies are secreted by a plasma cell which is a type of white blood cell.
  • Antibodies occur in two physical forms, a soluble form that is secreted from the cell, and a membrane-bound form that is attached to the surface of a B cell and is referred to as the B cell receptor (BCR). Soluble antibodies are released into the blood and tissue fluids, as well as many secretions to continue to survey for invading microorganisms .

  • the majority of antibodies comprise two heavy chains and two light chains. There are several different types of antibody heavy chains, and several different kinds of antibodies, which are grouped into different isotypes based on which heavy chain they possess. Five different antibody isotypes isotypes (IgA, IgD, IgE, IgG and IgM) are known in mammals and trigger a different immune response for each different type of foreign object, epitope or microbe they encounter.

  • the binding of an antibody to an antigen has no direct biological effect. Rather, the significant biological effects are a consequence of secondary "effector functions" of antibodies.
  • the immunoglobulins mediate a variety of these effector functions. These functions include fixation of complement, binding of phagocytic cells, lymphocytes, platelets, mast cells, and basophils which have immunoglobulin receptors. This binding can activate the cells to perform some function.
  • Some antibodies or immunoglobulins also bind to receptors on placental trophoblasts, which results in transfer of the immunoglobulin across the placenta. As a result, the transferred maternal antibodies provide immunity to the fetus and newborn.

It is typically conjugated with the chelator tiuxetan, which facilitates attachment of a radioisotope such as yttrium-90 or indium- 111. It is often administered in coordination with Rituximab which also targets CD20. The two antibodies share similar VH domains. In some cases, administration is used to treat refractory non-Hodgkin's lymphoma (NHL) that develops after primary cancer treatment (Wagner, H.N. et al, 2002. J Nucl Med. 43(2):267-72.)

  • Immunoglobulin E is a member of the immunoglobulin family that is secreted by, and expressed on the surface of B-cells or B-lymphocytes. IgE mainly functions as an immune defender against parasites. IgE also plays an essential role in type I hypersensitivity, which manifests various allergic diseases, such as allergic asthma, allergic rhinitis, food allergy, and some types of chronic urticaria and atopic dermatitis. In addition, IgE plays a pivotal role in allergic conditions, such as anaphylactic reactions to certain drugs, bee stings, and antigen preparations used in specific desensitization immunotherapy. The IgE molecules (e.g.
  • allergen-specific and allergen-nonspecific IgE bind to the high affinity IgE receptor (FcsRI) on the surface of mast cells and basophils.

  • the allergenic proteins bind to the allergen-specific IgE bound by FcsRI on the surface of mast cells and basophils and trigger the activation of those inflammatory cells, which release a host of inflammatory mediators, such as histamine, leukotrienes, tryptase, inflammatory cytokines, and other factors, causing various allergic symptom/diseases.
  • IgE binds to B-celis (as well as to monocytes, eosinophils and platelets) through its Fc region to a low affinity IgE receptor, known as FcsRII.
  • omalizumab's binding to IgE can neutralize circulating IgE by preventing IgE from binding to its high-affinity mast-cell receptor, therefore blocking IgE signaling.
  • Possible mechanisms may include 1) inhibiting Erkl/2 MAPK to stimulate airway (smooth muscle) cell proliferation and remodeling; 2)
  • the immune complexes formed between IgE and omalizumab in vivo are relatively small (molecular weight ⁇ 1 million) and are therefore unlikely to cause organ damage.
  • Omalizumab function as an anti-IgE antagonist, blocking IgE mediated allergic reactions and other clinical conditions.
  • Allergic asthma also called extrinsic asthma
  • extrinsic asthma is airway obstruction and inflammation that is partially reversible with medication. It has been estimated that as high as 20 to 40% of the populations who live in economically advanced countries are affected by allergy and seek medical help. According to Asthma and Allergy Foundation of America, Allergic asthma is the most common form of asthma in USA, affecting over 50% of the 20 million asthma sufferers. Over 2.5 million children under age 18 suffer from allergic asthma. Many of the symptoms of allergic and non-allergic asthma are the same (coughing, wheezing, shortness of breath or rapid breathing, and chest tightness). However, allergic asthma is triggered by inhaled allergens such as dust mite allergen, pet dander, pollen, mold, etc. resulting in asthma symptoms.
  • Immunoglobulin E is the antibody in the body that plays a major role in allergic diseases.
  • the body produces the IgE antibody when it detects an allergen and causes the "allergic cascade" to begin. While allergy occurs more frequently in individuals with higher serum IgE levels, such a correlation is only statistical and not absolute. Some allergic individuals have very low serum IgE, and some people with very high IgE have no allergic problems.
  • Anti-IgE antibodies have been an attractive strategy for treating allergic diseases such as asthma, (see, Thomson and Chauhuri, Clin Med Insights Circ Respir Pulm Med., 2012, 6, 27-40; the content of which is incorporated herein by reference in its entirety.)

  • the coding regions of the tocilizumab polynucleotides may encode any of the regions or portions of the tocilizumab antibody. They may also further comprise coding regions not found in the original or parent tocilizumab antibody.
  • the tocilizumab polynucleotides of the present invention may be engineered to produce any of the 5 standard classes of immunoglobulins as shown in Figure 1 using the tocilizumab antibody or any of its component parts as a starting molecule.
  • the tocilizumab polynucleotides may also be engineered according to the present invention to produce a variant tocilizumab antibody which is selected from one of (a) an intrabody, (b) a bicistronic or pseudobicistronic antibody, (c) a single domain antibody, either VHH or dAb, (d) a single chain variable fragment (scFv) antibody, and (e) a bispecific antibody which may comprise any two regions from two different antibodies, e.g., dAb or VHH.
  • a variant tocilizumab antibody which is selected from one of (a) an intrabody, (b) a bicistronic or pseudobicistronic antibody, (c) a single domain antibody, either VHH or dAb, (d) a single chain variable fragment (scFv) antibody, and (e) a bispecific antibody which may comprise any two regions from two different antibodies, e.g., dAb or VHH.
  • tositumomab polynucleotides or constructs and their associated tositumomab compositions are designed to produce the tositumomab antibody, a variant or a portion thereof in vivo.
  • Tositumomab (synonyms: Ig gamma- 1 chain C region; anti-Bl antibody) is a cell specific anti-CD20 antibody, mainly used to treat non-Hodgkin's lymphoma and lymphocytic leukemia, in particular, for the treatment of CD20 antigen expressing relapsed or refractory, low grade, follicular, or transformed non-Hodgkin's lymphoma, including patients with rituximab-refractory non-Hodgkin s lymphoma.
  • Tositumomab is usually applied with a sequential infusion followed by iodine tositumomab, which is the same antibody covalently bound to the radionuclide iodine-131.
  • the tositumomab/iodine- 131 tositumomab regimen (also called the Bexxar therapeutic regimen), as an
  • antineoplastic radioimmunotherapeutic monoclonal antibody-based regimen has established the efficacy in treating relapsed or chemotherapy/rituxan refractory follicular lymphoma in patients.
  • Tositumomab is a human-murine chimeric IgG2a lambda ( ⁇ ) antibody against human antigen CD20, which is a transmembrane phosphoprotein expressed on pre-B- lymphocytes and mature B lymphocytes.
  • Tositumomab is a dimer, containing 2 heavy chains of 451 residues and 2 mouse monoclonal BlRlgammer2a-chain, disulfide with mouse monoclonal B1R1 ⁇ chain with 220 residues.
  • Tositumomab was humanized from the mouse antibody anti-Bl (obtained from the Hall 299-15 ceil line) by Kaminski and Wahl et al (see, e.g. US Pat. NOs:
  • This chimeric antibody comprises the Bl antigen-binding domain (CD20 binding) and a human Fc and hinge region.
  • the amino acid sequences of chimeric heavy chain and light chain are listed in 26.
  • Tositumomab binds to the CD20 antigen, which is predominantly expressed on mature B cells and on >90% of B-cell non-Hodgkin's lympohomas.
  • the antibody leads to selective killing of B-cells.
  • the Bexxar regimen composing of tositumomab/iodine-131 tositumomab can delivers radiation, which enhances the killing effect of the antibody. Normal B cells then will recover in 6-9 months because the parent B-cells do not express the CD20 anti gen.
