Campath-1H in renal transplantation: The University of Wisconsin experience.

BACKGROUND: Immune cell depletion is known to prevent renal allograft rejection and injury. We evaluated the humanized monoclonal antibody Campath-1H (alemtuzumab; ILEX Oncology, San Antonio, Texas) in renal transplant recipients for its safety and efficacy in preventing rejection when used in combination with a calcineurin inhibitor, mycophenolate mofetil, and low-dose steroid therapy. METHODS: One hundred twenty-six consecutive renal allograft recipients received 2 doses of Campath-1H antibody on days 0 and 1. Outcomes were compared to patients who received an anti-CD25 antibody (n=799), Thymoglobulin (n=160), or other antibody treatment (n=156) in combination with a calcineurin inhibitor, mycophenolate mofetil, and higher dose steroids. RESULTS: The Campath-1H group overall experienced less rejection than the other 3 groups (P=.037). Patients with delayed graft function experienced less rejection with Campath-1H than control groups (P=.0096) and improved graft survival (P=.0119). There was no difference in infection or malignancies between the 4 groups. CONCLUSIONS: Campath-1H was well tolerated in renal transplant patients and led to significant reductions in incidence of rejection. Patients with delayed graft function experienced significantly improved graft survival.
