Overview

This investigational combination regimen, developed by Northwestern University's Comprehensive Transplant Center, is designed to induce immunologic tolerance in HLA-identical sibling kidney transplant recipients. The protocol utilizes alemtuzumab (Campath-1H), a monoclonal antibody targeting the CD52 antigen, as an induction agent to deplete host lymphocytes and monocytes. This is followed by infusions of purified donor CD34+ hematopoietic stem cells (DHSC) to establish cellular chimerism and donor-specific unresponsiveness. The ultimate goal of the regimen is to allow for the complete withdrawal of maintenance immunosuppressive therapy within 24 months post-transplant. Clinical trial results from NCT00619528 have demonstrated durable tolerance in a subset of patients, potentially eliminating the long-term side effects associated with chronic immunosuppression.
