Study Start Date: October 2011
Study Completion Date: July 2014
Primary Completion Date: May 2014 (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.
