Primary Outcome Measures:
  • Number of Participants With Dose Limiting Toxicity (DLT) [ Time Frame: Up to 3 weeks ] [ Designated as safety issue: No ]
    For DLT evaluation, severity (grade) was classified according to common terminology criteria for adverse events version 4.0 (CTCAE v4.0). DLTs were defined as grade 4 neutropenia persisting for more than 7 days; grade 3 or above febrile neutropenia; grade 4 thrombocytopenia or grade 3 thrombocytopenia requiring blood transfusion; non-hematologic toxicity (excluding toxicity related to neutrophils, leukocytes, lymphocytes, platelets, CD4 lymphocytes, anemia, and bone marrow density) greater than or equal to grade 3 (Exceptions: Dose reduction was not required even when the following conditions were met: grade 3 nausea, vomiting, or diarrhea controllable with anti-emetic or anti-diarrheal medication and abnormal laboratory parameter not requiring treatment); and day 8 administration was delayed or skipped as a result of the subject did not meet the dosing riteria within cycle.

  • Number of Participants With Adverse Events [ Time Frame: From signing of informed consent up to 30 days after participant's last treatment dose or up to approximately 2 years ] [ Designated as safety issue: Yes ]
    The number of subjects who developed 'treatment-emergent adverse events (AEs) and serious adverse events (SAEs) were evaluated.

Enrollment: 12
Study Start Date: October 2011
Study Completion Date: December 2013
Primary Completion Date: August 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1 Drug: E7389
Eribulin mesylate (iv) will be administered on Day 1 and Day 8 of each cycle (3 weeks as 1 cycle). Trastuzumab (iv) will be administered as weekly use or tri-weekly use. Trastuzumab will be administered immediately after eribulin mesylate administration when used concomitantly.
