Reporting Groups

	Description
Ixabepilone + Capecitabine	Ixabepilone in combination with capecitabine (combination group): Ixabepilone 40 mg/m2 administered as a 3-hour intravenous (IV) infusion on Day 1 of each cycle only, plus oral capecitabine 1000 mg/m2 twice a day (BID) (2000 mg/m2 daily dose) x 14 days, followed by 1 week of rest.
Capecitabine	Capecitabine alone: Capecitabine 1250 mg/m2 BID (2500 mg/m2 daily dose) x 14 days, followed by 1 week of rest.

[1]	Karnofsky Performance Scale Index measures a patient's functional impairment: 100-80=able to carry on normal activity and work, no special care; 70-50=unable to work; able to live at home and care for most personal needs with assistance; 40=unable to care for self; requires institutional or hospital care. Score reported in multiples of 10.
