A Randomized, Open-label Study of the Effect of Herceptin Plus Arimidex Compared With Arimidex Alone on Progression-free Survival in Patients With HER2-positive and Hormone-receptor Positive Metastatic Breast Cancer

Type of Study:

Interventional

Study Design:

Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Outcome Measure:

Progression Free Survival (PFS)

Outcome Description:

PFS was assessed by the investigator based on World Health Organization (WHO) criteria using radiographic tumor evaluations. Disease progression was defined as the appearance of any new lesion not previously identified or an estimated increase of 25% or more in existent bidimensionally or unidimensionally measurable lesions or progression of an existing non-measurable lesion. For bidimensionally measurable malignant lesions with an area of at least 2.0 centimeters squared (cm^2) an increase of 1.0 cm^2 was required and for unidimensionally measurable lesions of 1.0 cm or less an increase of 0.5 cm was required. PFS was defined as the number of days between date of randomization and date of documented disease progression or date of death. Kaplan Meier estimates of PFS are presented.
