Several new anti-CD20 monoclonal antibodies directed
against lymphoid cells have been developed and investigated
in preclinical studies and clinical trials [8]. The results
of preclinical and clinical studies suggest that therapy which
uses monoclonal antibodies (mAbs) directed at a target
other than CD20 can be useful in treating CLL [9]. Such
treatments include lumiliximab (anti-CD23), epratuzumab
(anti-CD22), apolizumab (anti-MHC-II), galiximab (anti-
CD80), anti-CD40 monoclonal antibodies and TRU-016,
a small modular immunopharmaceutical (SMIP) derived
from the fusion of key domains of an anti-CD37 antibody
with a human protein.
