Campath in Chronic GVHD

Summary

The CD52 antigen, which is targeted by alemtuzumab, is highly expressed on mature T lymphocytes, monocytes and monocyte-derived dendritic cells as well as on mature B cells. Due to its more promiscuous effect on immune cells, alemtuzumab not only targets antibody producing B lymphocytes as does rituximab, but also targets alloreactive T lymphocytes and dendritic cells that also contribute to the complex pathogenesis of chronic GVHD. Our hypothesis is that alemtuzumab will be effective in the treatment of chronic GVHD through its promiscuous depletion of alloreactive T lymphocytes, dendritic cells as well as antibody producing mature B-lymphocytes.
