Trial Outcomes & Findings for A Study of Herceptin (Trastuzumab) in Women With Metastatic Breast Cancer (NCT NCT00475670)

NCT ID: NCT00475670

Last Updated: 2014-09-15

Results Overview

CR was defined for target lesions (TLs) as the disappearance of all lesions, and for nontarget lesions (NTLs) as the disappearance of all nontarget nonmeasurable lesions. PR was defined for TLs as at least a 30 percent (%) decrease from baseline (BL) in the sum of longest diameter (SLD) of TLs. 95% confidence interval for one-sample binomial using Pearson-Clopper method.

PRIMARY outcome

Timeframe: Baseline (BL); Day 1 of Weeks 7, 13, 19, 25, 37, and 52, at the last administration of study treatment, every 24 weeks thereafter until disease progression for up to 6 months after the last participant was recruited

Population: FAS; Cohort A (trastuzumab monotherapy) was closed prematurely due to enrollment difficulties. Therefore, Cohort A included only 3 participants and none of the data from these 3 participants were analyzed for any of the specified endpoints.

CR was defined for target lesions (TLs) as the disappearance of all lesions, and for nontarget lesions (NTLs) as the disappearance of all nontarget nonmeasurable lesions. PR was defined for TLs as at least a 30 percent (%) decrease from baseline (BL) in the sum of longest diameter (SLD) of TLs. 95% confidence interval for one-sample binomial using Pearson-Clopper method.

Population: FAS. Duration of response was assessed in participants with a best overall response of CR or PR. Cohort A (trastuzumab monotherapy) was closed prematurely due to enrollment difficulties. Therefore, Cohort A included only 3 participants and none of the data from these 3 participants were analyzed for any of the specified endpoints.

Duration of response was defined as the time from first confirmed CR or PR until death or progressive disease (PD). For TLs, PD was defined as at least a 20% increase in the SLD of the TL, taking as reference the smallest SLD recorded since the beginning of treatment or the appearance of one or more new lesions. For NTLs, PD was defined as the appearance of one or more new lesions or unequivocal progression of existing non target non-measurable lesions. Participants were censored at the date of the last tumor assessment.
