ARM C: CP-4055 in combination with idarubicin

1. Patients with relapsed/refractory AML for which no standard therapies are anticipated to result in a durable response or who have failed potentially curative therapy, or who refuse or are considered unsuitable for standard therapy

ARM A, B, C: CP-4055 as single agent and/or in combination with idarubicin

2. Patients must be 18 years of age or older

3. Patients must have ECOG performance status (PS) of 0 - 2. See Appendix 3

4. Women of child-bearing potential (i.e., women who are pre-menopausal or not surgically sterile) must have a negative serum or urine pregnancy test within 2 weeks prior to beginning treatment on this study. Nursing patients are excluded.

7. Patients must have the following clinical laboratory values:

• Serum creatinine less or equal to 1.5 x the institutional upper limit of normal (ULN)

• Total bilirubin less or equal to 1.5 x the ULN unless considered due to Gilbert's syndrome

• Alanine aminotransferase (ALT) (SGPT), or aspartate aminotransferase (AST) (SGOT) less or equal to 2.5 x the ULN unless considered due to organ leukemic involvement
