Primary Outcome Measures:
  • Progression free survival in week 12 [ Time Frame: in week 12 ] [ Designated as safety issue: No ]

    A progression event is defined as (whichever occurs first):

    • Progressive disease (PD) assessed according to the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1
    • Death of any cause
    • Starting of second line treatment
    • No tumor assessment 85 days (+/- 7 days) after registration which shows stabilisation or response Patients without tumor assessment at week 12 but with a later assessment showing absence of progression without subsequent treatment will be counted as a progression free at week 12

Secondary Outcome Measures:
  • Quality of life (QL) [ Time Frame: Baseline, in week 7, 13 and 19 ] [ Designated as safety issue: No ]
  • Adverse events (CTCAE v 4.0) [ Time Frame: Adverse events are assessed by Common terminology criteria for adverse events (CTCAE) v4.0. From randomization until 30 days after end of treatment (estimated up to 2 years). ] [ Designated as safety issue: Yes ]
  • Overall Response (OR) [ Time Frame: Before start of treatment. In week 13 and every 12 weeks up to 2 years. ] [ Designated as safety issue: No ]
  • Progression free survival (PFS) [ Time Frame: PFS will be calculated sustained from randomization until documented PD or death, whichever occurs first (estimated up to 2 years). ] [ Designated as safety issue: No ]
  • Overall Survival (OS) [ Time Frame: Overall survival will be calculated from randomization until death (estimated up to 2 years). ] [ Designated as safety issue: No ]
  • Overall treatment utility (OTU) (predefined composite endpoint including clinical benefit, tolerability and acceptability of the treatment) [ Time Frame: Until week 19. ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Active Comparator: Arm A: Cetuximab
Cetuximab 500 mg/m2 every 2 weeks
Drug: Cetuximab
Cetuximab 500 mg/m2 every second week (days 1, 15, 29, etc.) until progression or unacceptable toxicity
Other Name: Erbitux
Active Comparator: Arm B: Cetuximab and Capecitabine

Cetuximab 500 mg/m2 every 2 weeks plus Capecitabine 1000 mg/m2 (*) bid d1-14 every 3 weeks

* 750 mg/m2 if creatinine-clearance 30-50 ml/min

Drug: Cetuximab
Cetuximab 500 mg/m2 every second week (days 1, 15, 29, etc.) until progression or unacceptable toxicity
Other Name: Erbitux
Drug: Capecitabine
Capecitabine 1000 mg/m2 bid p.o. (750 mg/m2 if creatinine clearance 30-50 ml/min according to Cockroft-Gault formula, on days 1-14 every 3 weeks, restart on day 22
Other Name: Xeloda

Detailed Description:

Primary endpoint: If in a treatment arm the number of patients alive and without progression at 12 weeks is 17 or more, this arm will be considered promising, otherwise not promising. Additionally, a two-sided 95% confidence interval for the difference in Progression free survival (PFS) rates between the two arms will be calculated.

Secondary endpoints and patient characteristics:

  • Laboratory values may be expressed as the absolute values (continuous variables) or/and as grading (ordinal categorical variables).
  • Generally for each categorical variable the results will be summarized by frequencies and percentages. For response rates 95% Clopper-Pearson confidence intervals will be calculated.
  • For each adverse event, the results will be summarized by frequencies and percentages of different grades among all cycles as well as by frequencies and percentages of the within-patient worst grades
  • For each continuous variable the results will be summarized by descriptive statistics.
  • Time-to-event variables will be presented by Kaplan-Meier curves and summarized by medians and 95% confidence intervals.
  • All analysis will be done by treatment arm.
