Cycle 1 day 1: radio-labeled dose of 2 mg radioactive eribulin, followed by 1.4 mg/m^2 of non-radio-labeled eribulin thereafter on days 1 and 8 every 21 days.
Other Name: E7389
The study will be conducted in two phases, the initial Study phase to administer the radio-labeled 14C-eribulin and collection of PK samples, and the Extension Phase when the patients will continue to receive non-radio-labeled eribulin. In the initial Study phase, patients will receive a single 2 mg flat dose of 14C-eribulin (approximately 80 to 90 microCuries) administered on Cycle 1 Day 1 as an intravenous (IV) bolus injection or infusion over 2-5 minutes. Following this initial dose, patients will remain in the research unit until Day 8 to complete sample collections of urine, blood and feces for PK analysis and determination of 14C-eribulin concentrations between Days 1 and 8.
On Day 8 patients will be re-assessed and discharged, and return on day 15 for physical exam, adverse event evaluation, and lab tests. The patients will then enter the Extension Phase of the study and continue to receive on-radio-labeled eribulin at a dose of 1.4 mg/m^2 on Days 1 and 8 of every 21 day cycle.
