A method for the production of a monoclonal antibody to CD20 for the treatment of B-Cell Lymphoma

摘要

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.
