Pilot Trial of Arsenic + Cytarabine in Patients With Myelofibrosis

Completed · Early Phase 1

Conditions studied: Myelofibrosis

In brief

This is an open-label, one arm, single institution study. Arsenic trioxide \[TrisenoxTM Injection\], 0.25mg/kg/dose administered intravenously over 2 hours. 20 patients Complete remission, partial remission, clinical improvement, progressive disease, stable disease, relapse (per IWG consensus criteria, 2006) Clinical chemistry, hematology and ECGs will be assessed at least weekly during study treatments. Adverse events will be assessed in accordance with the NCI Common Toxicity Criteria, Version 2 at each study visit.

You may qualify if…

• Patients > = 18 years with a documented history of myelofibrosis transformed to acute myeloid leukemia using the World Health Organization criteria of > = 20% blasts in the peripheral blood or bone marrow; the diagnosis of myelofibrosis could be either primary myelofibrosis (myelofibrosis with myeloid metaplasia, agnogenic myeloid metaplasia), post-polycythemia vera or post-essential thrombocytosis.
• Patients > = 18 years with myelofibrosis (either primary (myelofibrosis with myeloid metaplasia, agnogenic myeloid metaplasia), post polycythemia vera or post essential thrombocytosis) who 1) meet the Mayo Clinic criteria for high risk disease (> = 2 of the following criteria: hemoglobin <10 g/dL, WBC <4 or >30 x 109/L, platelets < 100 x 109/L, absolute monocyte count > = 1 x 109/L) AND 2) have failed to respond to treatment with at least one prior therapy for myelofibrosis (erythropoietic cytokines, androgens, hydrea, interferon, thalidomide, lenalidomide or investigational therapy).
• Patients must have discontinued prior myelofibrosis treatments (with the exception of hydrea, which is permitted for control of leukocytosis) for at least 14 days prior to starting study drug
• ECOG performance status of < = 2
• Serum creatinine < = 2.5 times the upper limit of normal
• Serum bilirubin < = 2.5 times the upper limit of normal
• Serum potassium >4.0 mEq/dL and serum magnesium >2.0 mg/dL. If these serum electrolytes are below the specified limits on the baseline laboratory tests, electrolytes will be administered to bring the serum concentrations to these levels before administering arsenic trioxide.
• Patients will be eligible for this trial regardless of gender, racial/ethnic background, provided all other inclusion and exclusion criteria are met and the patient or patient's legally authorized guardian signs the informed consent.

You may not qualify if…

• Pregnant or lactating women
• Presence of a (9;22) translocation cytogenetically, or presence of bcr-abl by FISH (fluorescence in situ hybridization) or PCR (polymerase chain reaction)
• Absolute QT interval >500 msec in the presence of serum potassium ≥ 4.0 mEq/L and magnesium > = 1.8 mg/dL.
• Prior cytotoxic chemotherapy for AML or MDS; prior treatment with hydroxyurea, 5-azacytidine, decitabine, thalidomide and lenalidomide are permitted. Prior treatment with low-dose cytarabine is not permitted.
• Concurrent treatment with maintenance therapy, cytotoxic chemotherapy, radiation, or investigational agents.
• Uncontrolled or severe cardiovascular, pulmonary or infectious disease or other medical condition that would prohibit use of the planned study treatments.
• Inability or unwillingness to comply with the treatment protocol, follow-up, or research tests.
