Study Summary

This randomized, multicenter, 2-arm, open-label study (TH3RESA) will evaluate the efficacy and safety of trastuzumab emtansine (T-DM1) in comparison with treatment of the physician's choice in participants with metastatic or unresectable locally advanced/recurrent human epidermal growth factor receptor 2 (HER2)-positive breast cancer. Eligible participants will be randomized to receive either trastuzumab emtansine 3.6 mg/kg intravenously every 21 days or treatment of the physician's choice. Participants continue to receive study treatment until disease progression or unacceptable toxicity occurs. This study is also known under Roche study protocol number BO25734.

Primary Outcome

Progression-free survival was defined as the time from randomization to the first documented disease progression by investigator assessment using Response Evaluation Criteria In Solid Tumors (RECIST) v1.1 or death from any cause, whichever occurred first. Progression-free survival was a co-primary endpoint.
