Pinatuzumab vedotin incorporates the humanized anti-CD22 monoclonal IgG1 antibody Hu10F4 and a microtubule inhibitor monomethyl auristatin E. Pinatuzumab vedotin demonstrated better anti-tumor activity than the standard rituximab plus CHOP regimen in a xenograft model bearing Ramos cells and also showed anti-lymphoma effects in vitro [49]. This evidence concerns the gene CD22 and neoplasm.
