This phase I trial studies the side effects and the best dose of brentuximab vedotin when given together with mitoxantrone hydrochloride, etoposide, and cytarabine in treating patients with CD30 positive acute myeloid leukemia that has returned or does not respond to treatment. Monoclonal antibody-drug conjugates, such as brentuximab vedotin, may block cancer growth in different ways by targeting certain cells. Drugs used in chemotherapy, such as mitoxantrone hydrochloride, etoposide, and cytarabine, 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. Giving brentuximab vedotin together with mitoxantrone hydrochloride, etoposide, and cytarabine may kill more cancer cells.

PRIMARY OBJECTIVES:
I. To define the maximum tolerated dose (MTD) of the cluster of differentiation (CD)30 antibody drug conjugate brentuximab vedotin in combination with mitoxantrone hydrochloride, etoposide, and cytarabine (MEC) re-induction chemotherapy in patients with relapsed or refractory acute myeloid leukemia and expression of CD30.
II. To evaluate the safety and tolerability of brentuximab vedotin in combination with MEC re-induction in adults with acute myeloid leukemia.
SECONDARY OBJECTIVES:
I. To detect and categorize, according to severity, the cumulative incidences of drug related toxicities.
II. To determine the response rate, including rates of complete and partial remission.
III. To measure the one-year disease-free and overall survival after treatment.
IV. To assess CD30 status by flow cytometry in enrolled patients throughout study course and correlate with immunohistochemistry (IHC) status.
V. To assess pharmacodynamic effects of CD30 targeted therapy with this antibody-drug conjugate (ADC), including measurement of soluble CD30 and CD30 ligand levels, as well as CD30 staining.
OUTLINE: This is a dose-escalation study of brentuximab vedotin.
RE-INDUCTION THERAPY: Patients receive brentuximab vedotin intravenously (IV) over 30 minutes on day 1 and mitoxantrone hydrochloride IV over 6-10 minutes, etoposide IV over 60 minutes, and cytarabine IV over 60 minutes on days 3-7. Patients achieving complete response and blood count recovery by day 40 who do not qualify for, are unable, or unwilling to undergo hematopoietic stem cell transplantation proceed to maintenance therapy.
MAINTENANCE THERAPY: Patients receive brentuximab vedotin IV over 30 minutes on day 1. Treatment repeats every 21 days for up to 12 months in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for up to 12 months.
