A Phase I / II Dose Escalation and Randomised Controlled Trial of ColoAd1 Administered by Sub-acute Fractionated Intravenous Injection to Patients with Metastatic Colorectal Cancer

Phase I: - To evaluate the safety and tolerability of ColoAd1, when administered by sub-acute fractionated IV injection to patients with advanced or metastatic epithelial solid tumours not responding to standard therapy or for whom no standard treatment exists - To determine the maximally-tolerated dose (MTD) and/or maximum-feasible dose (MFD) of ColoAd1 when administered by sub-acute fractionated intravenous (IV) injection to patients with advanced or metastatic epithelial solid tumours not responding to standard therapy or for whom no standard treatment exists, and to recommend a dose for phase II studies. Phase II: - To evaluate the progression free survival (PFS) in patients with metastatic colorectal cancer, who receive ColoAd1 administered by sub-acute fractionated IV injection as an intensification of first line chemotherapy compared with first line chemotherapy alone.
