OBJECTIVES:
Primary
-To evaluate the efficacy in terms of overall survival (OS) at 24 months of a chemotherapy-free dual HER2-inhibition with trastuzumab and pertuzumab (first-line) followed by T-DM1 (second-line) and of a chemotherapy-containing dual HER2-inhibition with trastuzumab and pertuzumab (first-line) followed by T-DM1 (second-line) in patients with HER2-positive metastatic breast cancer.
Secondary
- To evaluate other efficacy parameter
- To evaluate the safety and tolerability profile of the two treatment strategies
- To evaluate the Quality of Life (QoL)
- To learn how patients are treated after trial treatment

- Overall survival (OS) - Analysis Population: ITT Population 1 [ Time Frame: 24 months ]Patients being alive 24 months after randomization. A success is considered if a patient is alive at least 24 months after randomization. Analysis Population: ITT Population 1
- OS - Analysis Population: ITT Population 2 [ Time Frame: 24 months ]Proportion of patients being alive 24 months after randomization. A success is considered if a patient is alive at least 24 months after randomization. Analysis Population: ITT Population 2
- Progression Free Survival (PFS) of first-line treatment ignoring first Central Nervous System (CNS) lesion [ Time Frame: 10 / 16 months (PFS will be calculated sustained from randomization until documented PD (ignoring first CNS lesion) or death, whichever occurs first during first-line treatment ) ]
PFS of first-line treatment ignoring first CNS lesion is the time from randomization to first event progression. A PFS of first-line treatment ignoring first CNS lesion event is defined as (whichever occurs first):
- Disease progression (PD) after having received first-line treatment and prior to the next treatment
- Death due to any reason Patients without events will be censored at last tumor assessment date without PFS ignoring first CNS lesion event during the first-line treatment period or prior to starting new treatment.
Analysis population: ITT Population 1
- PFS of second-line treatment [ Time Frame: 8 months (PFS will be calculated sustained from registration of second line treatment until documented PD, PD CNS or death, whichever occurs first during second-line treatment) ]
PFS of second-line treatment is the time from registration of second-line treatment to progression. A PFS event of second-line treatment is defined as (whichever occurs first):
- Disease progression after having received second-line treatment and prior to the next treatment
- PD CNS after having received first-line treatment and prior to the next treatment
- Death due any reason during the second-line treatment period Patients without events will be censored at last tumor assessment date without PD and PD CNS during the second-line treatment period or prior to starting new treatment.
Analysis Population: ITT Population 2
- PFS of second-line treatment ignoring first CNS lesion [ Time Frame: 9 months (PFS will be calculated sustained from registration of second line treatment until documented PD (ignoring first CNS lesion) or death, whichever occurs first during second-line treatment) ]
PFS of second-line treatment ignoring first CNS lesion is the time from registration of second-line treatment to the first event occurs. A PFS of second-line treatment ignoring first CNS lesion event is defined as (whichever occurs first):
- Disease progression after having received second-line treatment and prior to the next treatment
- Death due any reason during the second-line treatment period Patients without events will be censored at last tumor assessment date without PFS ignoring first CNS lesion event during the second-line treatment period or prior to starting new treatment.
Analysis Population: ITT Population 2
- Time to failure of strategy (TFS) of first- plus second-line treatment [ Time Frame: 18 / 24 months (TFS will be calculated sustained from randomization until documented PD, PD CNS or death, whichever occurs first before starting third-line therapy ) ]
TFS of first plus second-line treatment is the time from randomization to TFS event occurs. A TFS event of first plus second-line treatment is defined as (whichever occurs first):
- Disease progression after having received the first and second-line treatment and prior to the next treatment
- PD CNS after having received first- and second-line treatment and prior to the next treatment
- Death due to tumor prior to the third-line treatment Patients without events will be censored at last tumor assessment without PD and PD CNS during first and second-line treatment period or prior to starting new treatment.
Analysis Population: ITT Population 1
- Overall survival OS [ Time Frame: OS will be calculated from randomization until death (estimated median: 32 months) ]
OS will be calculated from randomization until death. Patients still alive or lost of follow up are censored at their last date known alive.
Analysis Population: ITT Population 1
- Objective response (OR) of first-line treatment (based on investigator assessment) [ Time Frame: 10 / 16 months (OR is defined as the best status of response CR or PR up to first progression or start of a new treatment) ]
- Disease control (DC) of first-line treatment (based on investigator assessment) [ Time Frame: 6 months (DC is defined as CR, PR or SD for 6 months after randomization and no PD at 6 month after randomization) ]
- OR of second-line treatment (based on investigator assessment) [ Time Frame: 9 months (OR is defined as the best status of response CR or PR after registration for second-line treatment up to second progression or start of a new treatment) ]
- DC of second-line treatment (based on investigator assessment) [ Time Frame: 6 months (DC is defined as the response CR, PR or SD for 6 months after registration of second-line treatment) ]
- Adverse events (AEs) according to the NCI CTCAE v4.0 of first-line treatment [ Time Frame: Throughout first-line treatment (estimated up to 16 months) ]Adverse events are assessed by the NCI CTCAE v4.0. from registration until registration of second-line treatment or start of follow-up (which occurs first).
- AEs according to the NCI CTCAE v4.0 of second-line treatment [ Time Frame: Throughout second-line treatment (estimated up to 9 months) ]Adverse events are assessed by the NCI CTCAE v4.0.from second-line registration until PD or start of follow-up (which occurs first) plus 30 days.
- AEs grade ≥2 until first progression (ignoring first CNS lesion) [ Time Frame: Throughout first-line treatment (estimated up to 16 months) ]Adverse events are assessed by Common terminology criteria for adverse events (CTCAE) v4.0. From randomization until first progression (documented PD, PD CNS or death)
- Quality of Life (QoL) [ Time Frame: At baseline and every 12 weeks (three-monthly) until progression or up to a maximum of 24 months during 1st line therapy. Within 3 weeks prior to registration, after 12 and 24 weeks during 2nd line therapy. ]
- PFS of third-line treatment [ Time Frame: 4 months ]PFS will be calculated sustained from start of third-line treatment to progression (PD, PD CNS or death)

SELECTION OF PATIENTS (MOST IMPORTANT CRITERIA)
Inclusion criteria for first-line therapy
• Histologically confirmed breast cancer with distant metastases
Note:
- A biopsy from the primary tumor or a metastasis can be used for diagnosis.
- Patients with non-measurable lesions are eligible.
- Patients with inoperable, locally advanced breast cancer with lymph node metastases other than ipsilateral locoregional (axillary, infraclavicular, parasternal) or other distant metastases are eligible.
- Patients with bone metastases with or without bone targeted therapy (bisphosphonates, denosumab) are eligible.
-
Patients with de-novo Stage IV disease are eligible.
- HER2-positive tumor according to central pathology testing for HER2
Note:
- A formalin-fixed paraffin-embedded (FFPE) biopsy from the primary tumor or a metastasis has to be used for HER2 status determination. If a biopsy is available from a metastasis, the HER2 testing should be performed using the metastasis.
