Trial Outcomes & Findings for A Study of E7389 in Advanced/Metastatic Breast Cancer Patients (NCT NCT00097721)

NCT ID: NCT00097721

Last Updated: 2013-04-22

Results Overview

Defined as the percentage of subjects with CR or PR from the start of treatment until disease progression or recurrence. Lesions measured by computed tomography (CT) scan and magnetic resonance imaging (MRI). Objective response rate: complete response (CR-disappearance of all lesions)+ partial response (PR-30% decrease in lesion diameter), Progressive Disease (PD-20% increase in lesion diameter), stable disease (SD-neither shrinkage nor increase of lesions).

PRIMARY outcome

Timeframe: Confirmed 4 to 8 weeks after first observed

SECONDARY outcome

Timeframe: From CR or partial response PR (whichever recorded first) to date of recurrent or progressive disease

Population: Intent to Treat/Safety Population (Investigator Assessment)

Measured from the time measurement criteria were met for complete response (CR) or partial response (PR) (whichever was first recorded) until the first date that recurrent progressive disease was objectively documented (taking as a reference for progressive disease the smallest measurements recorded since the treatment started).

The FACT-B questionnaire consists of 36 questions each scored from 0-4. The total score is calculated by summing these scores. The total possible range is from 0 to 144. The higher scores indicate a better health-related quality of life. This measures emotional, functional, physical, and social well being as well as concerns specific to patients with breast cancer.
