Phase 2
Completed
Conditions
Metastatic Breast Cancer ( HER2 Negative)
Locally Recurrent
Interventions
Registration Number
NCT01268150
Lead Sponsor
Eisai Inc.
Brief Summary

The purpose of this study is to assess the efficacy and safety of single-agent eribulin mesylate for first-line treatment of subjects with locally recurrent or metastatic breast cancer.

Detailed Description

This is a multicenter, single-arm, Phase 2 trial to assess the efficacy and safety of single-agent eribulin mesylate for first-line treatment of subjects with locally recurrent or metastatic human epidermal growth factor receptor (HER2)-negative breast cancer. A total of 52 adult female subjects will be enrolled and treated with eribulin mesylate (1.4 mg/m2 as an intravenous \[i.v.\] infusion over 2 to 5 minutes on Days 1 and 8 of each 3-week cycle).

Primary Outcome Measures
NameTimeMethod
Objective Response Rate (ORR)Cycle 1 (Day 1) until first evidence of disease progression, assessed up to the data cutoff date (30 Aug 2013) up to 2.5 years

The ORR was defined as the percentage of participants with best overall response (BOR) of confirmed complete response (CR) or partial response (PR), based on Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. Targeted lesions were assessed by computed tomography (CT) and magnetic resonance imaging (MRI) which were then assessed by the investigator based on RECIST. CR was defined as the disappearance of all target lesions. PR was defined as at least 30% decrease in the sum of diameters of target lesions, taking as reference baseline sum diameters. Possible CR and PR had to be confirmed no fewer than 4 weeks after the initial response assessment. A brain and bone scan was performed by CT/MRI within 1 week after confirmation of a response to ensure no new metastases. To be assigned a status of CR or PR, changes in tumor measurements had to be confirmed by repeat evaluations, to be performed not fewer than 4 weeks after the response criteria were first met. ORR = CR + PR

Secondary Outcome Measures
NameTimeMethod
Time to First Response (CR or PR)Treatment Phase (Day 1 Cycle 1) to earliest date of confirmed objective response (CR or PR), assessed up to the data cutoff date (30 Aug 2013) up to 2.5 years

Time to first response was defined for participants whose BOR was a CR or PR. Analysis was based on the Kaplan-Meier estimated number of months to CR or PR. This statistical analysis method measures the effect of study drug on CR or PR.

Duration of ResponseFirst date of CR or PR to PD or Death from any cause, assessed up to the data cutoff date (30 Aug 2013) up to 2.5 years

Duration of response was measured for participants who were responders only, had attained a BOR that was CR or PR. The duration of response was measured from time that response criteria for CR or PR (whichever was recorded first) were first met until the date that progressive disease (PD) or death from any cause was first objectively documented. Participants who did not have PD were censored on the day of their last tumor assessment. Duration of response was summarized for the responders using Kaplan-Meier estimation method. This statistical analysis method measures the effect of study drug on the length of response time.

Progression-Free Survival (PFS)Treatment Phase (Day 1 Cycle 1) to date of progressive disease or death, whichever occurred first, assessed up to the data cutoff date (30 Aug 2013) up to 2.5 years

PFS was defined as the time from the date of the first dose of study drug until the date of first documentation of PD or date of death from any cause, whichever occurred first. Participants who died without reported PD were considered to have progressed on the day of their death. Participants who were lost to follow-up or alive and without reported PD at the end of study were censored on the date of their last tumor assessment. Participants without evidence of PD upon discontinuation of study drug during the Extension Phase returned to the clinic for disease evaluation and PFS calculation every 12 weeks until PD was documented. PFS was analyzed using Kaplan-Meier product-limit estimates. This statistical analysis method measures the effect of study drug on PFS.
