AB Lymphoma cells often express lymphokine receptors that provide a target
for therapy. For example, malignant cells of patients with
HTLV-1-associated adult T-cell leukemia/lymphoma (ATL) express IL-2
receptors. In contrast, normal resting cells do not express the IL-2
receptors identified by the anti-Tac monoclonal antibody. Using the
unmodified anti-Tac monoclonal antibody, one-third of the 19 patients
treated with ATL have undergone a remission. However, unmodified murine
monoclonal antibodies are limited by their immunogenicity and their poor
effector functions. To address these issues, we used genetic engineering
to produce humanized anti-Tac that contains the
complementarity-determining regions from the mouse with the remainder of
the antibody derived from human IgG1-kappa. Humanized anti-Tac is
dramatically less immunogenic than the murine versions and, in contrast
to the parent antibody, manifests antibody-dependent cellular
cytotoxicity with human mononuclear cells. To enhance its effector
function, anti-Tac was armed with toxins or with alpha- and
beta-emitting radionuclides. In a clinical trial with 90Y-anti-Tac, 11
of the 17 patients with ATL underwent a partial or sustained complete
remission. Thus, the clinical application of
lymphokine-receptor-directed therapy provides a new perspective for
treatment of certain lymphomas, including HTLV-1-associated ATL.
