Trial Outcomes & Findings for Trastuzumab (Herceptin), Bevacizumab, and Docetaxel (Taxotere) Trial in Stage IV Metastatic Breast Cancer (MBC) Patients (NCT NCT00428922)

NCT ID: NCT00428922

Last Updated: 2018-08-09

Results Overview

The trial was designed as a single-stage phase II rather then usual two-stage design because of the progression free survival (PFS) primary endpoint, as it is impractical to wait to assess PFS for patients in the first stage. We will consider a PFS of 50% at twelve months (median PFS of 12 months) or less uninteresting and a PFS of 70% at twelve months (median PFS of twenty months) worthy of pursuing the regimen in a future trials. The single-stage design is as follows: p0=0.50, p1=0.70, α=0.10, β= 0.10. This leads to a total sample size of 39 patients, 24 or higher of who are progression-free at 12 months.

14.3 months
Interval 9.3 to 35.0

SECONDARY outcome

Timeframe: Day 1 and Day 22

Population: Due to sample size, could not perform any statistical analysis to correlate the baseline CTCs with PFS and response rate. Samples only available for 50% of the patients.

Circulating tumor cells (CTCs) evaluated at baseline (day 1 of treatment) and after 1 treatment cycle (day 22 prior to cycle 2 treatment).

7 patients with detected CTCs

SECONDARY outcome

Timeframe: at least 24 weeks

Defined as best response of CR or PR or stable disease for at least 24 weeks. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI and/or CT: Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Stable Disease (SD), neither sufficient shrinkage to qualify for a Partial Response nor sufficient increase to qualify for Progression of Disease (POD); POD, 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions; Complete Response (CR), Disappearance of all target lesions

SECONDARY outcome

Timeframe: Day 1 and Day 22

Population: CEC data was not collected and available for analysis

Circulating endothelial cells (CECs) are to be collected day 1 prior to treatment and day 22 prior to treatment. These samples are to be collected at the PI's discretion based upon the availability of the cell processing laboratory, the patients will be informed when consented if the samples will collected or not.
