Primary Outcome Measures:
  • Maximum Tolerated Dose (MTD) [ Time Frame: 3 Weeks ]

Enrollment: 13
Study Start Date: July 2011
Study Completion Date: January 2016
Primary Completion Date: August 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: E7777 Biological: denileukin diftitox (E7777)
E7777 will be administered by intravenous (IV) infusion for 5 days from Day 1 through 5 of each cycle (21 days/cycle) with 8 cycles in maximum for E7777 alone therapy. E7777 dose will be escalated from 6 micro-g/kg/day to 12, 15 and then to 18 in a stepwise fashion.
