Arms & Interventions
Eribulin
Eribulin was administered at a dose of 1.4 milligrams per meters squared (mg/m\^2) (as eribulin 1.23 mg/m\^2) by a 2- to 5-minute intravenous infusion or as a diluted solution on Day 1 and Day 8 every 21 days.
Intervention: Eribulin mesylate
Outcomes
Primary Outcomes
Progression-free survival (PFS) rate at 6 months
Time Frame: 6 months
PFS rate at 6 months is estimated based on the tumor response evaluation and is defined as the proportion of participants alive and progression-free at 6 months from the initial treatment of eribulin.
Secondary Outcomes
- Tumor response rate (TRR)(From the start date of therapy with eribulin to the date of death from any cause or last follow-up (1 day to up to approximately 2 years))
- PFS in eribulin-treated breast cancer participants according to line of treatment for advanced disease and tumor subtype (receptor status and molecular subtype)(From the start date of therapy with eribulin to the date of disease progression or death from any cause (1 day to up to approximately 2 years))
- TRR in eribulin-treated breast cancer participants according to line of treatment for advanced disease and tumor subtype (receptor status and molecular subtype)(From the start date of therapy with eribulin to the date of death from any cause or last follow-up (1 day to up to approximately 2 years))
- Progression-Free Survival (PFS)(From the start date of therapy with eribulin to the date of disease progression or death from any cause (1 day to up to approximately 2 years))
- Number of participants with any treatment-emergent adverse event (TEAE)(6 months)
- Overall Survival (OS)(From the start date of therapy with eribulin to the date of death from any cause or last follow-up (1 day to up to approximately 2 years))
- Time to treatment failure (TTF)(From the first treatment with eribulin to discontinuation of treatment for any reason (1 day to up to approximately 2 years))
- OS in eribulin-treated breast cancer participants according to line of treatment for advanced disease and tumor subtype (receptor status and molecular subtype)(From the start date of therapy with eribulin to the date of death from any cause or last follow-up (1 day to up to approximately 2 years))
- PFS rate in eribulin-treated breast cancer participants comparing early (≤ third line) to late (≥ fourth line) use(From the start date of therapy with eribulin to the date of disease progression or death from any cause (1 day to up to approximately 2 years))
- OS in eribulin-treated breast cancer participants comparing early (≤ third line) to late (≥ fourth line) use(From the start date of therapy with eribulin to the date of death from any cause or last follow-up (1 day to up to approximately 2 years))
- TTF in eribulin-treated breast cancer participants comparing early (≤ third line) to late (≥ fourth line) use(From the first treatment with eribulin to discontinuation of treatment for any reason (1 day to up to approximately 2 years))
- TRR in eribulin-treated breast cancer participants comparing early (≤third line) to late (≥ fourth line) use(From the start date of therapy with eribulin to the date of death from any cause or last follow-up (1 day to up to approximately 2 years))
- Number of participants with the indicated action to TEAEs(6 months)
- Number of participants with TEAEs resulting in discontinuation of eribulin(6 months)
- Number of participants using supportive drugs to treat AEs(6 months)
- Median number of eribulin cycles(6 months)
- Number of participants experiencing a dose reduction(6 months)
- TTF in eribulin-treated breast cancer participants according to line of treatment for advanced disease and tumor subtype (receptor status and molecular subtype)(From the first treatment with eribulin to discontinuation of treatment for any reason (1 day to up to approximately 2 years))
