The first monoclonal antibody (MoAb) used for prevention and treatment of allograft rejection was OKT3, a murine antibody directed against the 20 000 Da molecular subunit linked to the T-cell antigen receptor [1]. Although several studies demonstrated the efficacy of OKT3 in the prevention and treatment of acute rejection (AR), its widespread clinical use was hampered by a number of serious side effects that can be summarized in four categories. The first, administration of the drug is often accompanied by a cytokine-release syndrome with high fever, chills, arterial hypertension and even pulmonary oedema as result of capillary leak. Secondly, a substantial number of patients will develop antibodies against the xenogeneic epitope that are responsible for decreased efficacy. Thirdly, cross-reactions with non-target tissue may produce thrombocytopenia and neutropenia or aseptic meningo-encephalitis. Lastly, a higher incidence of infectious complications and malignancies has been reported, suggesting over-immunosuppression.
