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.

- description
- 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). All other lesions (or sites of disease) should be identified as non-TLs and recorded at baseline. PD for TLs was defined as greater than or equal to (\>/=) 20 percent (%) increase in SLD, taking as reference smallest SLD recorded since treatment started or appearance of 1 or more new lesions. PD for non-TLs was defined as appearance of 1 or more new lesions and/or unequivocal progression of existing non-TLs. Percentage of Participants with PD by IRC or death from any cause was reported.

- Tumor response was assessed by an IRC according to modified RECIST. OR was defined as the percentage of participants with a complete response (CR) or partial response (PR). All measurable lesions up to a maximum of 5 per organ and 10 in total were identified as TLs and recorded at baseline. A sum of the longest diameter for all TLs was calculated as baseline SLD. For TLs, a CR was defined as the disappearance of all TLs and a PR was defined as \>/= 30% decrease in the SLD of TLs, taking as reference the baseline SLD. For non-TLs, a CR was defined as the disappearance of all non-TLs and a PR was defined as the persistence of 1 or more non-TLs. Confirmation of response at a consecutive tumor assessment at least 4 weeks apart was required. Participants without a post-baseline tumor assessment were considered non-responders. The percentage of participants with CR or PR by IRC was reported. The 95% CI was computed using Blyth-Still Casella exact CI method.

The FACT-B TOI-PFB subscale contained 24 items from 3 subsections of the FACT-B questionnaire: Physical well-being, functional well-being, and additional concerns for breast cancer participants (breast cancer subscale \[BCS\]). All items in the questionnaire were rated by the participant on a 5-point scale ranging from 0 ("not at all") to 4 ("very much"). The total score ranged from 0 to 96 with higher score indicating better perceived quality of life. The percentage of participants with symptom progression was reported.
