Antibody Comments
The anti-CD52 antibody GZ-402668 (GLD52; gatralimab) was developed by Sanofi for the treament of progressive multiple sclerosis. Having completed Phase 1 evaluation, Sanofi halted further development of this agent in early 2018.
Immunopharmacology Comments
CD52 (CAMPATH-1) is a short, glycosylphosphatidylinositol (GPI) anchored peptide expressed on lymphocytes and by cells of the male genital tract. CD52 is required for complement-mediated cell lysis and antibody-mediated cellular cytotoxicity. The approved monoclonal antibody, alemtuzumab targets this function of CD52. By attaching to sperm it may be associated with oocyte penetration and fertilisation.
