A Randomized, Multicentre, Open-Label, Phase III Study of Lapatinib Plus Capecitabine Versus Trastuzumab Plus Capecitabine in Patients With Anthracycline- or Taxane-Exposed ErbB2-Positive Metastatic Breast Cancer
Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment
Number of Participants With Central Nervous System (CNS) Metastases (as Assessed by Independent Review) as the Site of First Relapse
CNS relapse is defined as the appearance of >=1 enhancing lesion measuring >=6 millimeters (mm) on T1Weighted (T1W) Magnetic Resonance Imaging (MRI) without CNS symptoms that were considered to be unequivocal based on all relevant radiological features (e.g., associated T2W signal abnormality); the appearance of any enhancing lesion on T1W MRI with CNS symptoms; unequivocal finding of leptomeningeal disease (defined as the dissemination of cancer throughout the spinal fluid), with or without symptoms; and unequivocal finding of multifocal intraparenchymal lesions with or without symptoms. In the event of the appearance of a <6 mm lesions(s) without CNS lesions, or equivocal findings potentially suggesting leptomeningeal disease, these findings were followed with a subsequent scan within 6 weeks. If unequivocal progression was determined with the subsequent scan and/or CNS symptoms occurred, then CNS relapse crieria were met.
From randomization until disease progression, death, or discontinuation from the study (average of 10 months)
