Randomized Controlled Trial Comparative Study
CEREBEL (EGF111438): A Phase III, Randomized, Open-Label Study of Lapatinib Plus Capecitabine Versus Trastuzumab Plus Capecitabine in Patients With Human Epidermal Growth Factor Receptor 2-Positive Metastatic Breast Cancer.
CEREBEL compared the incidence of CNS metastases as first site of relapse in patients with human epidermal growth factor receptor 2-positive metastatic breast cancer receiving lapatinib-capecitabine or trastuzumab-capecitabine. ⋯ CEREBEL is inconclusive for the primary end point, and no difference was detected between lapatinb-capecitabine and trastuzumab-capecitabine for the incidence of CNS metastases. A better outcome was observed with trastuzumab-capecitabine in the overall population. However, lapatinib-capecitabine efficacy may have been affected by previous exposure to a trastuzumab regimen and/or when treatment was given as first- or second-line therapy in the metastatic setting.

Randomized Controlled Trial Multicenter Study Comparative Study
Lapatinib or Trastuzumab Plus Taxane Therapy for Human Epidermal Growth Factor Receptor 2-Positive Advanced Breast Cancer: Final Results of NCIC CTG MA.31.
The efficacy of lapatinib versus trastuzumab combined with taxanes in the first-line setting of human epidermal growth factor receptor 2 (HER2) -positive metastatic breast cancer (BC) is unknown. ⋯ As first-line therapy for HER2-positive metastatic BC, lapatinib combined with taxane was associated with shorter PFS and more toxicity compared with trastuzumab combined with taxane.
