Drug: anti-EGFR-IL-dox

immunohistochemistry, assessed by central pathologist

- Measurable or evaluable disease according to RECIST 1.1

- No prior systemic treatment for metastatic or inoperable disease

- Adequate bone marrow function: neutrophils = 1.5 x 109/L, platelets = 100 x 109/L

- Adequate hepatic function: total bilirubin = 1.5 x ULN; AST, ALT and AP = 2.5 x ULN
(AST, ALT and AP = 5 x ULN if hepatic metastases are the only reason for enzyme
elevation)

- Adequate renal function: serum creatinine = 1.5 x ULN and calculated creatinine
clearance > 30 mL/min, according to the formula of Cockcroft-Gault.

- Adequate cardiac function: Left Ventricular Ejection Fraction (LVEF) = 40% as
determined by either echocardiography (ECHO) or radionuclide angiocardiography (MUGA)

Exclusion Criteria:

- Evidence of CNS or leptomeningeal metastases (even if previously treated); CNS imaging
not required in asymptomatic patients

- History of hematologic or primary solid tumor malignancy, unless in remission for at
least 5 years from registration. Inclusion of adequately treated cervical carcinoma in
situ or localized non-melanoma skin cancer is permitted independent of time since
diagnosis

- Previous therapy with more than 240 mg/m2 of doxorubicin or more than 450 mg/m2 of
epirubicin

- Previous radiotherapy for the metastatic disease (palliative radiotherapy of only
non-target lesions is allowed)

- Adjuvant treatment must have been stopped at least 6 months before registration

- Any serious underlying medical condition (at the judgement of the investigator) which
could impair the ability of the patient to participate in the trial (e.g. active
autoimmune disease, uncontrolled diabetes, etc.)

- Breastfeeding

- Participation in any investigational drug trial within 4 weeks preceding treatment
start

- Any concomitant drugs contraindicated when administering Erbitux™ or Caelyx™ according
to the Swissmedic-approved product information

- Known hypersensitivity to trial drug(s) or to any component of the trial drug(s)

- Any other serious underlying medical, psychiatric, psychological, familial or
geographical condition, which in the judgment of the investigator may interfere with
the planned staging, treatment and follow-up, affect patient compliance or place the
patient at high risk from treatment-related complications.
