Primary Outcome Measures:
  • To evaluate the safety of TAS-108 administered on this schedule
  • To investigate the comparative concentrations of TAS-108 and its metabolites in tumor tissue and blood at steady-state
  • To determine the time to progression of TAS-108 administered on this schedule

Estimated Enrollment: 180
Study Start Date: May 2004
Study Completion Date: March 2008
Detailed Description:

The objective of this study is to investigate the efficacy and safety of TAS-108 administered in postmenopausal patients with locally advanced or locally recurrent inoperable or progressive metastatic breast carcinoma who have previously responded to one or two standard endocrine therapies, with or without one prior chemotherapy.
