In the first stage of ADEPT, the intravenously administered antibody–enzyme fusion protein MFECPHis is allowed to localise in the tumour. In the second stage, prodrug ZD2767P, based on a bis-iodo-phenol mustard is given after clearance of enzyme from the circulation. CP cleaves the glutamate moiety to generate the active drug ZD2767D.
