Kidney transplantation has evolved over the years from transplants between identically matched donors and recipients to successfully transplanting allografts across virtually any degree of donor-recipient human leukocyte antigen mismatch and ABO-incompatibility. Integral to these improved outcomes has been the development and deployment of a range of immunosuppressive agents. The addition of monoclonal and polyclonal antibodies as a standard part of overall immunosuppression has led to the improved outcomes by providing a robust and focused protection during the first few months of transplantation when allografts are most vulnerable to immune-mediated injury. Alemtuzumab is a recombinant anti-CD52 pan-lymphocyte depleting monoclonal antibody that has been in use for kidney transplantation since the late 1990s. Despite the many years of experience with alemtuzumab, its utilisation in the UK has remained relatively restrained. This may be due to a lack of high-level evidence to support its safety and efficacy in transplantation. Also, long-term outcomes have not been addressed by existing studies. Nevertheless, available evidence suggests that alemtuzumab is associated with a lower risk of acute rejection within the first year of transplantation while exhibiting a comparable safety profile to non-lymphocyte depleting agents. Despite the current economic advantages of alemtuzumab (available free of cost on a named transplant recipient basis), its use in UK transplant centres has remained limited, variating from non-use, through usage in selected high immunologic risk subjects, to use as routine induction immunosuppression. This review discusses the current use of alemtuzumab for immunosuppression induction in kidney transplantation. It describes its evolution from development to its present application in kidney transplantation and reviews the evidence underpinning its utilisation. The role of alemtuzumab in the immunosuppressive protocols individual UK kidney transplant centres is also described.
