What was measured
Symptom progression was defined as the documentation of a \>/= 5-point decrease from baseline in the scoring of responses as measured by the Functional Assessment of Cancer Therapy-for participants with Breast Cancer (FACT-B) questionnaire with the Trial Outcomes Index-Physical/Functional/Breast (TOI-PFB) subscale. 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.
Analysis population: ITT population included all randomized participants on the basis of the treatment assigned at randomization. Only female participants with a Baseline assessment and at least 1 follow-up assessment were included in the analysis.
Groups in this outcome
Trastuzumab Emtansine
Participants received trastuzumab emtansine 3.6 mg/kg IV infusion over 30-90 minutes on Day 1 of each 21-day treatment cycle until PD (as assessed by the investigator), unmanageable toxicity, or study termination.
Lapatinib + Capecitabine
Participants received lapatinib 1250 mg (five 250 mg tablets) orally once daily during each 21-day cycle + capecitabine 1000 mg/m\^2 orally twice daily on Days 1-14 of each 21-day treatment cycle until PD (as assessed by the investigator), unmanageable toxicity, or study termination. Participants of this group were allowed to cross over to receive trastuzumab emtansine based on statistically significant OS benefit in favor of trastuzumab emtansine demonstrated in second interim analysis.
