E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to determine whether BIBW 2992 and vinorelbine i.v. prolongs progression-free survival (PFS) in comparison to trastuzumab and vinorelbine i.v. |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives are:
- further evaluation of efficacy (best RECIST assessment, overall survival, tumour shrinkage),
- health status (ECOG, weight)
- quality of life
- safety (adverse events, laboratory)
- pharmacokinetics |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
At selected sites and on patient consent: Exploratory biomarkers sub-study on fresh biopsies.
date and version: same as main protocol
The objective is to investigate the rationale of EGFR/HER1 and HER2 inhibition by BIBW 2992 over only HER2-inhibition by trastuzumab.
The drug impact on a certain biomarkers must be investigated in fresh tissue, as up-or down-regulation of certain target proteins and EGFR-phosphorylation are transient processes |
|
E.3 | Principal inclusion criteria |
•patients with metastatic HER2-positive breast cancer
•no prior HER2-targeted treatment other than trastuzumab allowed
•no prior vinorelbine treatment allowed
•patients should have received prior taxane and/or anthracycline containing chemotherapy
•patients must have progressed on one prior trastuzumab treatment, i.e. patients with:
- First-line metastatic breast cancer failing on adjuvant trastuzumab or within 12 months of completion of adjuvant trastuzumab treatment; prior trastuzumab treatment must have been at least 9 weeks
- Second-line metastatic breast cancer failing on first-line trastuzumab or within 6 months of completion of first-line trastuzumab treatment; prior trastuzumab treatment must have been at least 6 weeks
•Must have (archived) tumour tissue sample available for central re-assessment of HER2-status and prove HER2-positive. HER2 status must be confirmed by sponsor contracted laboratory prior to randomisation.

20.Known or suspected active drug or alcohol abuse.
21.Requirement for treatment with any of the prohibited concomitant medications listed in section 4.2.2.1.
22.Any contraindications for therapy with vinorelbine or trastuzumab.
23.Known hypersensitivity to BIBW 2992 or the excipients of any of the trial drugs.
24.Use of any investigational drug within 4 weeks of randomisation.

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint of this study is progression-free survival, defined as the time from the date of randomisation to the date of disease progression, or to the date of death if a patient died earlier. The analysis will be based upon the evaluation of tumour imaging as reviewed by an independent central unit, blinded to treatment assignments.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The primary analysis of PFS will be conducted when at least 484 patients have progressed (based on central review) or died. |
|
E.5.2 | Secondary end point(s) |
- Best RECIST assessment
- Overall survival |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
The first analysis will be performed at same timepoint than primary analysis
A second overall survival analysis should be performed approximately 42 months after the start of recruitment. |

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
The trial will be terminated as soon as the last patient has completed the last additional follow-up visit documenting the disease progression or the start of new treatment. In case patients would still be on treatment when the report of the trial is being performed, these patients will either be included in a follow-up trial or alternatively kept on treatment in this trial. Those patients will then be reported in an addendum to the report. |
