This work represents studies carried out at Mount Vernon Hospital and UCL, and sponsored by Cancer Research UK, between 2003 and 2006. Phase I/II Clinical trial studies of the vascular disrupting agent Combretastatin A4 Phosphate (CA4P) are presented - in combination with cytotoxic chemotherapy (Paclitaxel and Carboplatin), and radioimmunotherapy. Dynamic Contrast Enhanced MRI data from the studies is presented and discussed, and a supporting immunohistochemistry correlation study of vascular markers is also presented.
