Chemotherapy and Biological Therapy in Treating Patients With Chronic Phase Chronic Myelogenous Leukemia
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining biological therapy with chemotherapy may kill more cancer cells.
PURPOSE: Phase II trial to study the effectiveness of chemotherapy with cytarabine and homoharringtonine and biological therapy with interferon alfa in treating patients with chronic phase chronic myelogenous leukemia.
OBJECTIVES: I. Determine the effectiveness of low dose cytarabine, homoharringtonine, and interferon alfa in stimulating a complete cytogenic response in patients with Philadelphia chromosome positive early chronic phase chronic myelogenous leukemia. II. Evaluate the duration of the cytogenic response in these patients after this treatment. III. Determine differential success rates and analyze results by prognostic subsets (e.g., risk group, splenomegaly, thrombocytosis, age, etc.) in this patient population.
OUTLINE: Patients receive debulking therapy consisting of hydroxyurea until blood count is at proper level. Patients then receive interferon alfa and cytarabine daily by subcutaneous injection. Homoharringtonine is administered by continuous infusion on days 1-5. Treatment continues for 5-7 years in the absence of unacceptable toxicity or disease progression (accelerated or blastic phase CML). If complete remission is achieved, peripheral blood stem cells are collected. Patients are followed every 3 months for the first year and every 6 months thereafter.
PROJECTED ACCRUAL: A total of 100 patients will be accrued for this study within 3 years.

Medical and Biotech [MESH] Definitions
A recombinant alfa interferon consisting of 165 amino acids with arginine at positions 23 and 34. It is used extensively as an antiviral and antineoplastic agent.
A recombinant alfa interferon consisting of 165 amino acids with lysine at position 23 and histidine at position 34. It is used extensively as an antiviral and antineoplastic agent.
A recombinant alfa interferon consisting of 165 amino acid residues with arginine in position 23 and histidine in position 34. It is used extensively as an antiviral and antineoplastic agent.
A pyrimidine nucleoside analog that is used mainly in the treatment of leukemia, especially acute non-lymphoblastic leukemia. Cytarabine is an antimetabolite antineoplastic agent that inhibits the synthesis of DNA. Its actions are specific for the S phase of the cell cycle. It also has antiviral and immunosuppressant properties. (From Martindale, The Extra Pharmacopoeia, 30th ed, p472)
Congener of CYTARABINE that is metabolized to cytarabine and thereby maintains a more constant antineoplastic action.
A Phase II open-label trial of subcutaneous HHT (omacetaxine mepesuccinate) in the treatment of patients who are resistant to or intolerant to Tyrosine Kinase Inhibitors.
To evaluate the safety and efficacy of subcutaneous administration of omacetaxine mepesuccinate (HHT) in achieving a clinical response in CML patients in chronic, accelerated, or blast pha...

RATIONALE: Biological therapies such as interferon-alfa and STI571 may interfere with the growth of cancer cells. It is not yet known if STI571 is more effective than interferon alfa plus...
RATIONALE: Interferon alfa may interfere with the growth of cancer cells. Low doses of interferon alfa may be as effective as high doses. PURPOSE: Randomized phase III trial to compare th...
Omacetaxine mepesuccinate was originally identified more than 35 years ago and initial studies in chronic myeloid leukemia (CML) showed promising activity. It has also been studied in other hematologi...
Cytarabine (ara-C) is an important drug in the treatment of acute myeloid leukemia (AML). High-dose cytarabine (2000 to 3000 mg per square meter of body-surface area) is toxic but results in higher ra...
Gemtuzumab ozogamicin (GO), an anti-CD33 immunoconjugate, was combined with high dose cytarabine (HiDAC; cytarabine 3g/m(2) over 3h daily for 5 days) for adults with relapsed or refractory AML. HiDAC...
Abstract Background: After a first course of induction chemotherapy, 30 to 40% of patients with acute myeloid leukemia (AML) do not achieve complete response (CR). A second course of anthracyclins and...
