Details and patient eligibility


This was 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 was also evaluated.

Full description

Male or female patients ≥18 years of age with a histologically confirmed locally advanced and/or metastatic solid organ tumor. Patients enrolled in Germany were required to have a positive EGFR overexpression status. Patients must have experienced a failure or non-availability of standard therapy (had received at least one line of chemotherapy and further standard therapy was not an option at study entry). Open-label, non-randomized, inter-patient dose-escalation, multi-center study. Patients were to receive CetuGEX until disease progression or until intolerable toxicities occurred.


41 patients




18+ years old


No Healthy Volunteers
