Background
Epratuzumab Biosimilar uses the same protein sequences as the therapeutic antibody epratuzumab.
Epratuzumab is a humanized monoclonal antibody derived from the murine IG2a monoclonal antibody, LL2 (EPB-2). This agent may subsequently be well matched for use in oncology and the treatment of inflammatory autoimmune disorders, such as lupus.
Epratuzumab is a recombinant, humanized monoclonal antibody directed against CD22, a cell surface glycoprotein present on mature B-cells and on many types of malignant B-cells. It binds with high specificity to normal B-cells and B-cell tumors at the third Ig-like domain of CD22. After binding to CD22, epratuzumab's predominant antitumor activity appears to be mediated through antibody-dependent cellular cytotoxicity (ADCC).
