This is a prospective, open label, multicenter study evaluating the safety, tolerability and pharmacokinetics of CetuGEX™ after intravenous administration in patients with EGFR positive, locally advanced and/or metastatic solid cancers. The effect of CetuGEX™ on the development of anti-drug antibodies and on tumour response will also be evaluated.

Primary Outcome Measures:
  • To evaluate the safety and tolerability profile of CetuGEX™ at various dose levels [ Time Frame: throughout the study ] [ Designated as safety issue: Yes ]
  • To define the recommended phase II dose and regimen [ Time Frame: throughout the study ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To make a preliminary evaluation of anti-tumour activity of CetuGEX™ in the selected patient population(s) [ Time Frame: throughout the study ] [ Designated as safety issue: No ]
  • To make a preliminary evaluation of anti-tumour activity of CetuGEX™ in the selected patient püopulation(s) [ Time Frame: throughout study ] [ Designated as safety issue: No ]
