  * Renal function: Serum creatinine less than or equal to 2.0 mg/dL;
  * Hepatic function: Bilirubin less than or equal to 1.5 mg/dL; AST and ALT less than or equal to 1.5 X the upper normal limit (ULN) unless liver metastases are present, then AST and ALT less than or equal to 5.0 x ULN.
* The subject must not be pregnant or lactating and all subjects (male and female) must use a contraceptive method deemed acceptable by the investigator while in the study and for up to two months following completion of therapy.
