The present invention provides novel anti-CD71 monoclonal antibodies, in
particular mouse-human chimeric anti-CD71 monoclonal antibodies,
advantageously associated to effector cells for triggering ADCC
mechanisms. Anti-CD71 antibodies, as well as pharmaceutical compositions
containing them, are useful for inhibiting proliferation and/or killing
malignant tumor cells, especially metastatic cutaneous and uveal melanoma
cells.
