Hemoglobin greater than or equal to 9 g/dL 2. Absolute neutrophil count greater than or equal to 1.5 x 109 cells/L 3. Platelet count greater than or equal to 75 x 109 cells/L 4. Serum creatinine less than or equal to 1.5 times the upper limit of normal (ULN) 5. Aspartate transaminase less than or equal to 2.5 times the ULN 6. Serum albumin greater than or equal to 3.0 g/dL 7. Total bilirubin less than or equal to the ULN Exclusion Criteria: * Be a pregnant or breast-feeding woman. Female patients must be postmenopausal, surgically sterile, or they must agree to use a barrier method of contraception.
