Trial Outcomes & Findings for Therapy With Bevacizumab (BEV), Epirubicin, and Cyclophosphamide Followed by Docetaxel Plus Trastuzumab and BEV Given as Neoadjuvant or Adjuvant Therapy for Women With Locally Advanced HER2 Positive Invasive Breast Cancer (NCT NCT00464646)

NCT ID: NCT00464646

Last Updated: 2021-10-25

Results Overview

The determination of pCR is performed by the local pathologist following examination of tissue (breast and nodes)removed at the time of surgery. The outcome measure is the number of participants with no histologic evidence of invasive tumor cells in the surgical breast specimen, axillary nodes, or SNs identified after neoadjuvant chemotherapy.

PRIMARY outcome

Timeframe: Assessed at time of surgery on average at 8 months

Population: 73 of the 76 patients in Cohort A were analyzed: 2 patients did not have surgery and 1 patient did not have the nodal status determined.

The determination of pCR is performed by the local pathologist following examination of tissue (breast and nodes)removed at the time of surgery. The outcome measure is the number of participants with no histologic evidence of invasive tumor cells in the surgical breast specimen, axillary nodes, or SNs identified after neoadjuvant chemotherapy.

PRIMARY outcome

Timeframe: Cohort A: Baseline, post-treatment with EC, 2-4 weeks after surgery, and 9, 12, 15, and 18 months from study entry. Cohort B: Baseline, post-treatment with EC, 2-3 weeks after the last dose of docetaxel, and 6, 9, 12, 15, and 18 months from study entry.

The number of cardiac events defined as NYHA Class III/IV CHF and cardiac death.To determine the rate of cardiac events (NYHA Class III/IV CHF and cardiac death) of a regimen of EC followed by THA when administered to: Cohort A as neoadjuvant therapy for HER-2 positive locally advanced (clinical stage IIIA, IIIB or IIIC breast cancer or Cohort B as adjuvant therapy for resected HER2-positive pN2 or pN3 (pathologic stage III) breast cancer. The number of participants with one or more cardiac events are being reported.
