What was measured

Duration of the objective response was defined as the time from the first tumor assessment that was judged to indicate that the patient had an objective response to the time of first documented disease progression using RECIST v1.1 per investigator assessment or death from any cause, whichever occurred first.

Analysis population: Randomized population: All participants who were randomized to the study. Only participants with an objective response were included in the analysis. Participants were included in the treatment group to which they were randomized.

Groups in this outcome

Trastuzumab Emtansine

Trastuzumab emtansine 3.6 mg/kg intravenously every 3 weeks until disease progression (as assessed by the investigator) or unmanageable toxicity.

Treatment of Physician's Choice

Treatment of physician's choice until disease progression (as assessed by the investigator) or unmanageable toxicity. The treatments included single-agent chemotherapy, single-agent or dual-agent hormonal therapy for hormone receptor positive-disease, and HER2-directed therapy.
