Study Summary

This is a Phase III, randomized, multicenter, international, 2-arm, open-label clinical trial designed to compare the safety and efficacy of trastuzumab emtansine (T-DM1) with that of capecitabine + lapatinib in participants with human epidermal growth factor receptor 2 (HER2)-positive locally advanced or metastatic breast cancer. Participants will be treated until disease progression (PD), unmanageable toxicity, or study termination. Once disease progression is reported, all participants will be followed for survival every 3 months until death, loss to follow-up, withdrawal of consent, or study termination.

Primary Outcome

PD was assessed by an IRC using modified Response Evaluation Criteria in Solid Tumors (RECIST). All measurable lesions up to a maximum of 5 per organ and 10 in total were identified as target lesions (TLs) and recorded at baseline. TLs should be selected on the basis of their size (those with the longest diameter) and their suitability for accurate repeated measurements either by imaging or clinically. A sum of the longest diameter for all TLs was calculated as baseline sum longest diameter (SLD
