* Adequate hepatic function as defined by aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels \</= to 2.5 x ULN and total bilirubin \</= to 1.5 x ULN. In the presence of liver metastasis, adequate hepatic function is defined as ALT and AST \</= 5 x ULN and total bilirubin \</= 3 x ULN. Alkaline phosphatase levels less than or equal to 2.5 x ULN. In the presence of extensive bone metastases, alkaline phosphatase is defined as less than or equal to 5 x ULN

* Women of child-bearing potential or men whose sexual partners are women of child-bearing potential must agree to use two methods of adequate contraception (e.g. hormonal and barrier method of birth control) prior to study entry, for the duration of the study, and for 21 days after the last dose of study medication. Acceptable methods of contraception include condoms, diaphragm ,birth control pills, birth control patch, hormonal injections, intrauterine device (IUD), surgical sterilization and/or under the skin implants

* Patients with a history of major surgery within 28 days of first receipt of study drug
* Nursing or pregnant women
