Cohort I \& II: eribulin mesylate (E7389) 1.4 mg/m2 intravenously over 2 - 5 minutes on Day 1 and Day 8 for 4 cycles

eribulin mesylate

Cohort 1: capecitabine 900 mg/m2 orally twice daily on Days 1 - 14 of a 21-day cycle for 4 cycles Cohort II: fixed dose of 1500 mg oral capecitabine twice daily, 7 days on then 7 days off for 4 cycles

capecitabine

This is a Phase 2, multicenter, single-arm, feasibility study evaluating eribulin in combination with capecitabine as an adjuvant chemotherapy regimen in approximately 65 subjects with early-stage (I-II), human epidermal growth factor receptor 2 (HER2)- normal, estrogen receptor (ER)-positive breast cancer.

Eribulin in Combination With Capecitabine for Adjuvant Treatment in Estrogen Receptor-Positive Early Stage Breast Cancer

A Phase II, Multicenter, Single-Arm, Feasibility Study of Eribulin in Combination With Capecitabine for Adjuvant Treatment in Estrogen Receptor-Positive Early Stage Breast Cancer

Relative Dose Intensity (RDI) is defined as the amount of drug administered over a specific time and is expressed as the fraction of that recommended for standard of care. The RDI for each participant was calculated as follows: (1) based on each participant's body surface area (BSA), a total planned dose for both eribulin (Dep) and capecitabine (Dcp) calculated for a full 4-cycle regimen; (2) actual total dose of eribulin (Dea) and capecitabine (Dca) for the full 4-cycle regimen as collected on the case report form; (3) overall RDI = (Dea/Dep + Dca/Dcp)/2. For each individual participant, the regimen was considered feasible if that participant was able to achieve an RDI of at least 85% of the 4 cycles of eribulin plus capecitabine treatment. Missing doses due to any reason was counted as zero in the RDI calculation.

Alopecia (hair loss) is a potential side effect of some chemotherapy agents. Chemotherapeutic drugs are toxic and could potentially harm the hair follicles (wear hair grows from) resulting in the hair falling out. It can occur in small patches on various parts of the body or all over the body and is usually temporary when related to cancer treatment. Cold cap therapy is one form of therapy for alopecia involving hair loss from the scalp. Wearing a cap or head covering with cold packs before, during, or after chemotherapy may help prevent hair loss as the cold narrows the blood vessels in the skin on your head which may lead to less of the drug reaching the hair follicles. Alopecia was one of the most common adverse events (AEs) related to eribulin only.

TEAEs (any grade) of alopecia and neuropathy were followed until resolution or the start of another treatment whichever occurred first. AEs were graded on a 5-point scale according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.0.

Eribulin mesylate (1.4 mg/m\^2) was injected directly as an IV infusion over 2 to 5 minutes on Day 1 and Day 8 of the 21-day cycle for a total of 4 cycles. Alternatively, eribulin mesylate could be diluted in up to 100 mL in 0.9% sodium chloride for IV infusion over 2 to 5 minutes. Capecitabine (900 mg/m\^2) was administered orally BID on Days 1 through 14 of a 21-day cycle for a total of 4 cycles. Capecitabine was to be taken approximately 30 minutes after breakfast and approximately 30 minutes after dinner.

Cohort 1: Eribulin Mesylate Plus 900 mg/m^2 Capecitabine

Eribulin mesylate (1.4 mg/m\^2) was injected directly as an IV infusion over 2 to 5 minutes on Day 1 and Day 8 of the 21-day cycle for a total of 4 cycles. Alternatively, eribulin mesylate could be diluted in up to 100 mL in 0.9% sodium chloride for IV infusion over 2 to 5 minutes. A fixed dose of capecitabine (1500 mg) was administered orally BID on a 7/7 schedule (7days on and 7 days off) for a total of 4 cycles. Capecitabine was to be taken approximately 30 minutes after breakfast and approximately 30 minutes after dinner.

Cohort 2: Eribulin Mesylate Plus 1500 mg Capecitabine

Eribulin mesylate (E7389) (1.4 mg/m\^2) was injected directly as an IV infusion over 2 to 5 minutes on Day 1 and Day 8 of the 21-day cycle for a total of 4 cycles. Alternatively, eribulin mesylate could be diluted in up to 100 mL in 0.9% sodium chloride for IV infusion over 2 to 5 minutes. A fixed dose of capecitabine (1500 mg) was administered orally BID on a 7/7 schedule (7days on and 7 days off) for a total of 4 cycles. Capecitabine was to be taken approximately 30 minutes after breakfast and approximately 30 minutes after dinner.
