BAFF-Neutralizing Interaction of Belimumab Related to Its Therapeutic Efficacy for Treating Systemic Lupus Erythematosus
ARTICLE DOI: 10.1038/s41467-018-03620-2 OPEN BAFF-neutralizing interaction of belimumab related to its therapeutic efficacy for treating systemic lupus erythematosus Woori Shin1, Hyun Tae Lee1, Heejin Lim1, Sang Hyung Lee1, Ji Young Son1, Jee Un Lee1, Ki-Young Yoo1, Seong Eon Ryu2, Jaejun Rhie1, Ju Yeon Lee1 & Yong-Seok Heo1 1234567890():,; BAFF, a member of the TNF superfamily, has been recognized as a good target for auto- immune diseases. Belimumab, an anti-BAFF monoclonal antibody, was approved by the FDA for use in treating systemic lupus erythematosus. However, the molecular basis of BAFF neutralization by belimumab remains unclear. Here our crystal structure of the BAFF–belimumab Fab complex shows the precise epitope and the BAFF-neutralizing mechanism of belimumab, and demonstrates that the therapeutic activity of belimumab involves not only antagonizing the BAFF–receptor interaction, but also disrupting the for- mation of the more active BAFF 60-mer to favor the induction of the less active BAFF trimer through interaction with the flap region of BAFF. In addition, the belimumab HCDR3 loop mimics the DxL(V/L) motif of BAFF receptors, thereby binding to BAFF in a similar manner as endogenous BAFF receptors. Our data thus provides insights for the design of new drugs targeting BAFF for the treatment of autoimmune diseases. 1 Department of Chemistry, Konkuk University, 120 Neungdong-ro, Gwangjin-gu, Seoul 05029, Republic of Korea. 2 Department of Bio Engineering, Hanyang University, 222 Wangsimni-ro, Seongdong-gu, Seoul 04763, Republic of Korea.

Xolair/Omalizumab
Therapeutic/Humanized Antibodies ELISA Kits ‘Humanized antibodies” are ‘Animal Antibodies’ that have been modified by recombinant DNA-technology to reduce the overall content of the animal- portion of immunoglobulin so as to increase acceptance by humans or minimize ‘rejection’. By analogy, if the hands of a mouse is actually responsible for grabbing things then ‘humanized-mouse’ will only contain the ‘mouse hands’ and the rest of the body will be human. Since the size of the IgGs is similar in mouse and human, the size of the native mouse IgG and the ‘humanized IgG’ does not significantly change. Antigen recognition property of an antibody actually resides in small portion of the IgG molecule called the ‘antigen binding site or Fab’. Therefore, humanized antibodies contain the minimal portion from the Fab or the epitopes necessary for antigen binding. The process of "humanization of antibodies" is usually applied to animal (mouse) derived monoclonal antibodies for therapeutic use in humans (for example, antibodies developed as anti-cancer drugs). Xolair (Anti-IgE) is an example of humanized IgG. The portion of the mouse IgG that remains in the ‘humanized IgG’ may be recognized as foreign by humans and may result into the generation of “Human Anti-Drug Antibodies (HADA). The presence of anti-Drug antibody (e.g., Human Anti-Rituximab IgG) that may limit the long-term usage the humanized antibody (Rituximab). Not all monoclonal antibodies designed for human therapeutic use need be humanized since many therapies are short-term. The International Nonproprietary Names of humanized antibodies end in “-zumab”, as in “omalizumab”. Humanized antibodies are distinct from chimeric or fusion antibodies. -

FOR RESEARCH USE ONLY! TM BioSim Omalizumab (Human) ELISA Kit rev 06/20 (Catalog # E4381-100, 100 assays, Store at 4°C) I. Introduction: Omalizumab is a recombinant DNA-derived humanized IgG1k monoclonal antibody that selectively binds to human immunoglobulin E (IgE). Omalizumab inhibits the binding of IgE to the high-affinity IgE receptor (FceRI) on the surface of mast cells and basophils. Reduction in surface-bound IgE on FceRI-bearing cells limits the degree of release of mediators of the allergic response. Omalizumab is used to treat severe, persistent asthma. BioSimTM Omalizumab ELISA kit has been developed for specific quantification of Omalizumab concentration in human serum or plasma with high sensitivity and reproducibility. II. Application: This ELISA kit is used for in vitro quantitative determination of Omalizumab Detection Range: 10 - 1000 ng/ml Sensitivity: 10 ng/ml Assay Precision: Intra-Assay: CV < 15%; Inter-Assay: CV < 15% (CV (%) = SD/mean X 100) Recovery rate: 85 – 115% with normal human serum samples with known concentrations Cross Reactivity: There is no cross reaction with native serum immunoglobulins and tested monoclonal antibodies such as infliximab (Remicade®), adalimumab (Humira®), etanercept (Enbrel®), bevacizumab, trastuzumab III.

FOR RESEARCH USE ONLY! TM BioSim anti-Ipilimumab (Yervoy®) (Human) ELISA Kit rev 07/18 (Catalog # E4398-100, 100 assays, Store at 4°C) I. Introduction: Ipilimumab (Yervoy®) is a fully human IgG1κ antibody that binds to CTLA-4 (cytotoxic T lymphocyteassociated antigen 4), a molecule on T- cells that is indicated for unresectable or metastatic melanoma. The absence or presence of CTLA-4 can augment or suppress the immune system's T-cell response in fighting disease. Ipilimumab is designed to block the activity of CTLA-4, thereby sustaining an active immune response in its attack on cancer cells. The proposed mechanism of action is indirect, and may be through T-cell - mediated anti-tumor immune responses. However, some patients develop unwanted immunogenicity, which leads to production of anti-drug-antibodies (ADAs) inactivating the therapeutic effects of the treatment and, in rare cases, inducing adverse effects. BioVision’s BioSimTM anti-Ipilimumab ELISA kit is designed to detect antibody against Ipilimumab with high specificity and sensitivity in biological matrices. II. Application: This ELISA kit is used for in vitro qualitative determination of antibody against Ipilimumab in serum and plasma Cross Reactivity: Ipilimumab (Yervoy®) infusion camouflages/masks the presence of antibody to Ipilimumab (ATP) in serum/plasma samples. Therefore, blood sampling time is critical for detection of ATP. It is convenient to obtain blood sample just before the infusion or at least 2 weeks after the infusion of Ipilimumab. III.

Anti-TNF-Α (Certolizumab), Humanized Antibody
FOR RESEARCH USE ONLY! rev 06/21 Anti-TNF-α (Certolizumab), Humanized Antibody CATALOG NO.: A2142-100 (100 µg) BACKGROUND DESCRIPTION: The research-grade biosimilar is a humanized TNF-α monoclonal antibody. The original monoclonal antibody (Certolizumab pegol (CZP)) consists of polyethylene glycol conjugated to the antigen-binding fragment of the humanized monoclonal antibody. The antibody targets and neutralizes soluble and membrane forms of tumor necrosis factor-alpha (TNF-α) and inhibits TNF-α mediated signaling in vitro. Unlike other TNF inhibitors, this antibody does not contain the Fc region. As a result, decreased Fc-mediated effects such as antibody-dependent cell-mediated cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC) are observed. The original monoclonal antibody received FDA approval to treat moderate to severe rheumatoid arthritis, Crohn’s disease, ankylosing spondylitis, and psoriatic arthritis.

Omalizumab, Xolair
XOLAIR® Omalizumab For Subcutaneous Use DESCRIPTION Xolair (Omalizumab) is a recombinant DNA-derived humanized IgG1k monoclonal antibody that selectively binds to human immunoglobulin E (IgE). The antibody has a molecular weight of approximately 149 kilodaltons. Xolair is produced by a Chinese hamster ovary cell suspension culture in a nutrient medium containing the antibiotic gentamicin. Gentamicin is not detectable in the final product. Xolair is a sterile, white, preservative-free, lyophilized powder contained in a single-use vial that is reconstituted with Sterile Water for Injection (SWFI), USP, and administered as a subcutaneous (SC) injection. A Xolair vial contains 202.5 mg of Omalizumab, 145.5 mg sucrose, 2.8 mg L-histidine hydrochloride monohydrate, 1.8 mg L-histidine and 0.5 mg polysorbate 20 and is designed to deliver 150 mg of Omalizumab, in 1.2 mL after reconstitution with 1.4 mL SWFI, USP. CLINICAL PHARMACOLOGY Mechanism of Action Xolair inhibits the binding of IgE to the high-affinity IgE receptor (FceRI) on the surface of mast cells and basophils. Reduction in surface bound IgE on FceRI-bearing cells limits the degree of release of mediators of the allergic response. Treatment with Xolair also reduces the number of FceRI receptors on basophils in atopic patients. Pharmacokinetics After SC administration, Omalizumab is absorbed with an average absolute bioavailability of 62%. Following a single SC dose in adult and adolescent patients with asthma, Omalizumab was absorbed slowly, reaching peak serum concentrations after an average of 7-8 days. The pharmacokinetics of Omalizumab are linear at doses greater than 0.5 mg/kg. -
