简要总结
This randomized pilot trial studies how well higher or lower dose cladribine, cytarabine, and mitoxantrone work in treating medically less fit patients with newly diagnosed acute myeloid leukemia or myeloid neoplasm. Drugs used in chemotherapy, such as cladribine, cytarabine, and mitoxantrone, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving cladribine, cytarabine, and mitoxantrone at higher or lower dose may work better in treating patients with newly diagnosed acute myeloid leukemia.
详细描述
PRIMARY OBJECTIVES:
I. To evaluate the feasibility of randomizing medically less fit adults with newly diagnosed acute myeloid leukemia (AML) or analogous myeloid neoplasms to either intensive or non-intensive induction and post remission chemotherapy.
EXPLORATORY OBJECTIVES:
I. To evaluate the attitude of patients and physicians toward randomization and explore reasons for treatment preference.
II. To evaluate whether the ability to assess fitness for intensive chemotherapy can be improved by an augmented treatment-related mortality (TRM) score that includes additional (co-morbidity) factors, and to compare the ability of physicians and the prediction algorithm(s) to assess the likelihood of early death.

入选标准
- •Diagnosis of untreated "high-grade" myeloid neoplasm (>= 10% myeloid blasts by morphology in bone marrow and/or peripheral blood) or AML other than acute promyelocytic leukemia (APL) with t(15;17)(q22;q12) or variants according to the 2016 World Health Organization (WHO) classification; patients with acute leukemias of ambiguous lineage are eligible; outside diagnostic material is acceptable as long as peripheral blood and/or bone marrow slides are reviewed at the study institution and cytogenetic/molecular information is available
- •Treatment-related mortality (TRM) score >= 13.1 as calculated with simplified model
- •The use of hydroxyurea before enrollment is permitted; hydroxyurea should be discontinued prior to start of study treatment. Patients with symptoms/signs of leukostasis, white blood cell (WBC) > 100,000/uL, or acute symptoms felt related to their high-grade myeloid neoplasm can be treated with leukapheresis or may receive up to 1 dose of cytarabine (up to 500 mg/m^2) anytime prior to study day 1
- •Patients may have received treatment (e.g. azacitidine/decitabine, lenalidomide, growth factors) for antecedent low-grade myeloid neoplasm
- •Left ventricular ejection fraction (LVEF) >= 45%, assessed within 3 months prior to registration, e.g. by multigated acquisition (MUGA) scan or echocardiography, or other appropriate diagnostic modality
- •Women of childbearing potential and men must agree to use adequate contraception beginning at the signing of the consent until at least 4 weeks after the last dose of study drug
- •Ability to understand and the willingness to sign a written informed consent document
排除标准
- •Myeloid blast crisis of chronic myeloid leukemia (CML), unless patient is not considered candidate for tyrosine kinase inhibitor treatment
- •Concomitant illness associated with a likely survival of < 1 year
- •Active systemic fungal, bacterial, viral, or other infection, unless disease is under treatment with anti-microbials and/or controlled or stable; patients with fever thought to be likely secondary to leukemia are eligible; known hypersensitivity to any study drug
- •Known hypersensitivity to any study drug used in this trial
- •Pregnancy or lactation
- •Concurrent treatment with any other anti-leukemia agent
