- Maximum-tolerated dose (MTD) of homoharringtonine as assessed by the National Cancer Institute (NCI) Common Terminology Criteria (CTC) [ Time Frame: 14 days ]
- Complete hematologic remission (CHR) defined as at least 4 weeks of bone marrow (less than 5% blasts) and peripheral blood with WBC < 10 x 10^9/L and no peripheral blasts, promyelocytes, or myelocytes [ Time Frame: Up to 6 years ]Using a Bayesian approach.

Experimental: Treatment (omacetaxine mepesuccinate)
Remission induction therapy: Patients receive remission induction therapy comprising homoharringtonine IV continuously over 24 hours on day 1 and then subcutaneously (SC) twice daily on days 2-14 for course 1. Subsequent courses of remission induction therapy comprise homoharringtonine SC twice daily on days 1-14. Treatment continues monthly for at least 2 courses. Maintenance therapy: Patients with complete hematologic remission receive maintenance therapy comprising homoharringtonine SC twice daily on days 1-7 monthly for 3 years in the absence of disease progression or unacceptable toxicity. |

Detailed Description:
OBJECTIVES:
I. Determine the maximum tolerated dose of homoharringtonine in patients with transformed phases of chronic myelogenous leukemia (CML). (Phase I completed as of 2/11/2004.) II. Determine the toxicity profile of this drug in these patients. III. Determine the response duration in patients with chronic phase CML treated with this drug.
IV. Compare the pharmacokinetics of this drug administered as a continuous infusion vs subcutaneously in these patients.
OUTLINE: This is a pilot, dose-escalation study. (Phase I completed as of 2/11/2004.)
Remission induction therapy: Patients receive remission induction therapy comprising homoharringtonine IV continuously over 24 hours on day 1 and then subcutaneously (SC) twice daily on days 2-14 for course 1. Subsequent courses of remission induction therapy comprise homoharringtonine SC twice daily on days 1-14. Treatment continues monthly for at least 2 courses.
Maintenance therapy: Patients with complete hematologic remission receive maintenance therapy comprising homoharringtonine SC twice daily on days 1-7 monthly for 3 years in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of homoharringtonine until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which 2 of 6 patients experience dose-limiting toxicity. An additional cohort of 25-30 patients with chronic phase chronic myelogenous leukemia receives remission induction and maintenance therapy as above at the MTD. (Phase I completed as of 2/11/2004.)
Patients are followed every 3 months.
PROJECTED ACCRUAL: A maximum of 50 patients will be accrued for this study.
