Type of Study:

Interventional

Study Design:

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

Outcome Measure:

Percentage of Participants Assessed for Pathological Complete Response (pCR) Plus Near Complete (npCR) in Primary Breast Tumor at Time of Definitive Surgery

Outcome Description:

Pathological complete response was defined as the absence of histological evidence of invasive breast cancer cells in the tissue specimen removed from the breast after 4 cycles of preoperative treatment. Near pCR (npCR) was defined as the presence of invasive tumor cells with a size of 5 mm or less in aggregate in the tissue specimen removed from the breast after 4 cycles of preoperative treatment. Only pathological assessments occurring prior to the first date of adjuvant treatment were included in the analysis of pCR rate.

Outcome Time Frame:

at the time of definitive surgery; after four 3-week cycles (3-4 months)
