Exclusion criteria: • Chemotherapy = 21 days before first study treatment • Trastuzumab = 21 days before first study treatment • Lapatinib = 14 days before first study treatment • Prior enrollment in a trastuzumab emtansine-containing study, regardless of whether the patient received prior trastuzumab emtansine • Brain metastases that are untreated or symptomatic, or require any radiation, surgery, or corticosteroid therapy to control symptoms within 1 month of randomization.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: - Progression-free survival (PFS) per investigator assessment - Overall survival (OS) ; Secondary Objective: • To evaluate the objective response rate (ORR) and landmark survival rate (6-month survival rate and 1-year survival rate) of trastuzumab emtansine compared with treatment of physician’s choice • To evaluate the safety of trastuzumab emtansine compared with treatment of physician’s choice. ; Primary end point(s): • Progression-free survival by investigator assessment • Overall survival ; Timepoint(s) of evaluation of this end point: • The primary PFS (by investigator assessment) analysis will be performed when approximately 324 PFS events have occurred, which is projected to be approximately 16 months from first patient enrolled in the trial (FPI). • The first OS interim analysis will be performed at the time of the primary PFS analysis (approximately 16 months from FPI); the second interim analysis will be performed when approximately 67% of the targeted deaths (492) have occurred (approximately 26 months from FPI). | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): • Objective response rate by investigator • Duration of objective response • Landmark survival rate. ;Timepoint(s) of evaluation of this end point: After either PFS or OS (at any interim or final analysis) shows statistical significance, the secondary endpoints will be tested sequentially. | — |
