HUMANIZED ANTIBODY AGAINST INTERLEUKIN-20 AND TREATMENT FOR INFLAMMATORY DISEASES

摘要

A humanized antibody, or a scFv, Fab, or F(ab')2 thereof, includes: a heavy chain variable region, or a homologous variant thereof, wherein the heavy chain variable region includes: heavy chain framework regions, CDRH1 that has the sequence of SEQ ID NO:19, CDRH2 that has the sequence of SEQ ID NO:20, and CDRH3 that has the sequence of SEQ ID NO:21, wherein the heavy chain variable region and the homologous variant share at least 90% sequence identity in the heavy chain framework regions; and a light chain variable region, or a homologous variant thereof, that includes: light chain framework regions, CDRL1 that has the sequence of SEQ ID NO:22, CDRL2 that has the sequences of SEQ ID NO:23, and CDRL3 that has the sequences of SEQ ID NO:24, wherein the light chain variable region and the homologous variant share at least 90% sequence identity in the light chain framework regions.
