Primary Outcome Measures:
  • Objective response rate (ORR) [ Time Frame: 30 months ]
    Defined as the proportion of subjects who have a best overall response of confirmed complete response (CR) or partial response (PR) based on Response Evaluation Criteria in Solid Tumors (RECIST) v. 1.1 as determined by the investigator.

Enrollment: 52
Study Start Date: December 2010
Estimated Study Completion Date: July 2016
Primary Completion Date: March 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1 Drug: Eribulin Mesylate

Eribulin mesylate 1.4 mg/m2 administered as an intravenous (IV) infusion (over 2 to 5 minutes) on Days 1 and 8 of each 3-week cycle.

Trastuzumab 8 mg/kg will be administered as in IV infusion over a 90-minute period on Day 1 of Cycle 1. Thereafter, trastuzumab 6 mg/kg will be administered as an IV infusion over a 30-minute period on Day 1 of each subsequent cycle.

Accepts Healthy Volunteers:   No

Key Inclusion criteria:

  • Age 18 years or older
  • Histologically or cytologically proven adenocarcinoma of the breast
  • Subjects who have locally recurrent or metastatic disease with at least one measurable lesion

  • Eastern Cooperative Oncology Group (ECOG) performance status (PS) score of 0, 1 or 2
  • At least 12 months since prior neoadjuvant or adjuvant chemotherapy
  • At least 2 weeks since prior radiotherapy, endocrine therapy, trastuzumab, or lapatinib, with complete recovery from the effects of these interventions
  • Adequate renal function
  • Adequate bone marrow function
  • Adequate liver function
  • Adequate cardiac function

Key Exclusion criteria:

  • Prior chemotherapy, biologic therapy, or investigational therapy for locally recurrent or metastatic HER2+ breast cancer.
  • Subjects who have had a prior malignancy other than carcinoma in situ of the cervix, or nonmelanoma skin cancer
  • Prior exposure to greater than 360 mg/m2 doxorubicin or liposomal doxorubicin, greater than 120 mg/m2 mitoxantrone, greater than 90 mg/m2 idarubicin, or greater than 720 mg/m2 epirubicin

  • Prior history of hypertensive crisis or hypertensive encephalopathy
  • Clinically significant cardiovascular impairment
  • Subjects with known central nervous system (CNS) disease are not eligible, except for those subjects with treated brain metastasis.
  • Subjects with metastatic disease limited to bone are ineligible unless there is at least one lytic lesion with identifiable soft tissue components that can be evaluated by computed tomography (CT) or magnetic resonance imaging (MRI)
  • Pulmonary lymphangitic involvement that results in pulmonary dysfunction requiring the use of oxygen
  • History of bleeding diasthesis
  • Currently pregnant or breast-feeding.
  • Subjects with preexisting Grade 3 or 4 neuropathy. Any peripheral neuropathy must recover to Grade less than or equal to 2 before enrollment
