Trial Outcomes & Findings for A Study of Herceptin (Trastuzumab) in Combination With a Taxane in Participants With HER2-Positive Breast Cancer Who Relapsed After (Neo)Adjuvant Herceptin Treatment (NCT NCT01301729)

NCT ID: NCT01301729

Last Updated: 2016-12-29

Results Overview

PFS was assessed according to Response Evaluation Criteria In Solid Tumors (RECIST) 1.0 and was defined as the time from the date when the participant signed the informed consent form (ICF) until death or progressive disease (PD). PD was defined as 20% increase in the sum of the longest diameter of target lesions. PFS and associated confidence intervals were calculated using the Kaplan-Meier method.

SECONDARY outcome

Timeframe: up to 28 months

Population: ITT data set is defined as all the participants who are eligible through screening, register and enter the study.

Overall response rate was assessed using RECIST 1.0 and defined as the percentage of participants that achieved a complete response (CR) or a partial response (PR). CR was defined as complete disappearance of all target and non-target lesions and no new lesions. PR was defined as greater than or equal to (≥) 30 % decrease in the sum of appropriate diameters of all target measurable lesions, no progress in the non-measurable disease, and no new lesions.

Timeframe: From the time of PR or CR until the date of PD or death (up to 28 months)

Population: ITT data set is defined as all the participants who are eligible through screening, register and enter the study. Here, number of participants are the participants who had response.

Duration of response was defined as the time from when a PR or CR was first documented until the date of documented PD or death. CR was defined as complete disappearance of all target and non-target lesions and no new lesions. PR was defined as greater than or equal to (≥) 30 % decrease in the sum of appropriate diameters of all target measurable lesions, no progress in the non-measurable disease, and no new lesions.
