Last verified: December 2013
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.

Condition Intervention Phase
Solid Tumors
Drug: CetuGEX™
Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Dose-escalation, PK- and Safety Study With Single Agent CetuGEX™ in Patients With EGFR Positive Locally Advanced and/or Metastatic Cancer

Further study details as provided by Glycotope GmbH:

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

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 ]
  • To make a preliminary evaluation of anti-tumour activity of CetuGEX™ in the selected patient püopulation(s) [ Time Frame: throughout study ]
