Brief summary

This phase I/II trial studies the side effects and best dose of mitoxantrone hydrochloride when given together with filgrastim, cladribine, and cytarabine and to see how well they work in treating patients with acute myeloid leukemia or high-risk myelodysplastic syndromes that is newly diagnosed, has returned, or does not respond to treatment. Drugs used in chemotherapy, such as filgrastim, cladribine, cytarabine, and mitoxantrone hydrochloride, 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.

Detailed description

PRIMARY OBJECTIVES: I. Estimate the maximum tolerated dose (MTD) of dose-intensified mitoxantrone hydrochloride (mitoxantrone) as part of the filgrastim (G-CSF), cladribine, cytarabine, mitoxantrone hydrochloride (G-CLAM) regimen separately for adults with newly diagnosed acute myeloid leukemia (AML) and those with relapsed/refractory AML receiving first or greater salvage therapy. SECONDARY OBJECTIVES: I. To determine, within the limits of a phase 1/2 study, disease response and duration of remission separately for patients with newly diagnosed and relapsed/refractory AML. II. To describe, within the limits of a phase 1/2 study, the toxicity profile of the study regimen separately for patients with newly diagnosed and relapsed/refractory AML. OUTLINE: This is a phase I, dose-escalation study of mitoxantrone hydrochloride followed by phase II study. INDUCTION CHEMOTHERAPY (G-CLAM): Patients receive G-CLAM chemotherapy comprising filgrastim subcutaneously (SC) daily on days 0-5, mitoxantrone hydrochloride intravenously (IV) over 60 minutes on days 1-3, cladribine IV over 2 hours daily on days 1-5, and cytarabine IV over 2 hours daily on days 1-5. Patients achieving complete remission with incomplete peripheral blood count recovery (CRi), partial remission, or persistent disease may receive a second course of induction chemotherapy. Patients achieving complete remission (CR) or CR with incomplete platelet count recovery (CRp) may continue on to Consolidation Chemotherapy. CONSOLIDATION CHEMOTHERAPY (G-CLA): Beginning within 6 weeks of achieving CR/CRp/CRi, patients receive G-CLA comprising filgrastim SC on days 0-5, cladribine IV over 2 hours daily on days 1-5, and cytarabine IV over 2 hours daily on days 1-5. Treatment continues for up to 4 courses in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up periodically for up to 5 years.

Inclusion criteria

* For patients with newly diagnosed disease: diagnosis of high-risk myelodysplastic syndrome (MDS) (\>= 10% blasts) or AML other than acute promyelocytic leukemia (APL) with t(15;17)(q22;q12) or variants according to the 2008 World Health Organization (WHO) classification; for patients with relapsed/refractory disease: prior diagnosis of high-risk MDS or non-APL AML, with relapsed/refractory disease according to standard criteria requiring first or subsequent salvage therapy; patients with biphenotypic AML are eligible * Outside diagnostic material is acceptable as long as peripheral blood and/or bone marrow slides are reviewed at the study institution; flow cytometric analysis of peripheral blood and/or bone marrow should be performed according to institutional practice guidelines * For patients with relapsed/refractory disease: patients with prior autologous or allogeneic hematopoietic cell transplantation (HCT) for MDS/AML are eligible if relapse occurs provided symptoms of graft-versus host disease are well controlled with stable use of immunosuppressive agents * Treatment-related mortality (TRM) score =\< 6.9 as calculated with simplified model * The use of hydroxyurea prior to study registration is allowed; patients with symptoms/signs of hyperleukocytosis or white blood cell (WBC) \> 100,000/uL can be treated with leukapheresis or may receive up to 2 doses of cytarabine (up to 500 mg/m\^2/dose) prior to enrollment * For patients with relapsed/refractory disease: patients may have previously received chemotherapy with a mitoxantrone- or cladribine-based regimen for MDS or AML; if that patient has received G-CLAM before and has been sensitive to this regimen, eligibility will be determined on a case-by-case basis by the study principal investigator (PI) * Should be off any active systemic therapy for AML with the exception of hydroxyurea for at least 14 days prior to study registration unless patient has rapidly progressive disease, and all grade 2-4 non-hematologic toxicities should have resolved * Bilirubin =\< 2.5 x institutional upper limit of normal (IULN) unless elevation is thought to be due to hepatic infiltration by AML, Gilbert's syndrome, or hemolysis (assessed within 14 days prior to study day 0) * Serum creatinine =\< 2.0 mg/dL (assessed within 14 days prior to study day 0) * Left ventricular ejection fraction \>= 45%, assessed within 3 months prior to study day 0, e.g. by multi gated acquisition scan (MUGA) scan or echocardiography, or other appropriate diagnostic modality and no clinical evidence of congestive heart failure; if the patient had anthracycline-based therapy since the most recent cardiac assessment, cardiac evaluation should be repeated if there is clinical or radiographic suspicion of cardiac dysfunction, or if the previous cardiac assessment was abnormal * Women of childbearing potential and men must agree to use adequate contraception * Provide written informed consent

Exclusion criteria

* 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 (e.g. if specific, effective therapy is not available/feasible or desired \[e.g. chronic viral hepatitis, human immunodeficiency virus (HIV)\]); patient needs to be clinically stable as defined as being afebrile and hemodynamically stable for 24 hours; patients with fever thought to be likely secondary to leukemia are eligible * Known hypersensitivity to any study drug * Pregnancy or lactation * Treatment with any other investigational agent
