Brief Summary
A subset of patients with acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) harbor rearrangements of the MLL gene, which are detected either by cytogenetic or fluorescent in situ hybridization evaluation at the time of diagnosis. A protein called DOT1L plays an important role in the malignant process in these leukemias. EPZ-5676 is a molecule that blocks the activity of DOT1L, and is therefore being evaluated in the treatment of patients with MLL-rearranged leukemias.

Outcome Measures
Primary Outcomes (2)
Determine the maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D) of EPZ-5676.
To determine the maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D) of EPZ-5676 as determined by incidence of protocol-specified dose-limiting adverse events.
12 months
To assess the safety and tolerability of EPZ-5676 administered as a continuous intravenous (CIV) infusion
Safety and tolerability will be assessed by the incidence of adverse events in patients treated with EPZ-5676 and the evaluation of adverse events, vital signs, physical examination, 12-lead ECG, and laboratory assessments.
22 months
Secondary Outcomes (2)
Determine the pharmacokinetic (PK) and pharmacodynamic (PD) profile of EPZ-5676
18 months
Evaluate early evidence of anti-tumor activity
18 months
Other Outcomes (2)
To determine cerebrospinal fluid (CSF) concentrations EPZ-5676 in pediatric patients receiving EPZ-5676 by CIV infusion
18 months
Analysis of tumor cells for somatic mutations as potential predictors of response
18 months
Study Arms (1)
EPZ-5676
EXPERIMENTALEPZ-5676 Dose escalation and expansion cohorts
Interventions
28-day continuous IV infusion of each 28-day cycle, given until disease progression or unacceptable toxicity develops.
Eligibility Criteria
You may qualify if:
- Age: \>3 months to \<18 years of age.
- Diagnosis: Patients must have documented relapsed/refractory ALL, AML, or acute leukemia of ambiguous lineage and meet the following criteria:
- Patients must have at least received an appropriate induction therapy regimen. Patients with persistent leukemia after induction therapy, or with recurrence of leukemia at any time during the course of treatment (including allogeneic HSCT) are eligible;
- Patients must have \> 10% leukemic blasts in the bone marrow;
- Patients must have rearrangement involving the MLL gene, including reciprocal chromosomal translocations involving 11q23 by FISH, cytogenetic analysis, polymerase chain reaction (PCR) or next-generation sequencing (NGS) OR partial tandem duplication (PTD) of MLL by PCR or NGS.
- Therapeutic Options: Patients must be ineligible or inappropriate for other treatment regimens known to have curative potential.
- Performance Level: Karnofsky \> 50% for pts \> 12 years; Lansky \> 50% for pts \< 12 years of age.
- Prior Therapy: Patients must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study.
- Myelosuppressive Chemotherapy:
- days must have elapsed since the completion of cytotoxic therapy
- Patients may receive hydroxyurea, low-dose cytarabine and/or glucocorticoids to control peripheral blood leukemic cell counts at study entry
- At least 7 days since the completion of therapy with hematopoietic growth factors
- At least 7 days since the completion of therapy with a biologic agent
- At least 21 days since receipt of chimeric antigen receptor therapy or other modified T cell therapy
- At least 60 days from prior total body irradiation (TBI)
- +6 more criteria
You may not qualify if:
- Patients with CNS 3 disease or symptomatic CNS disease
- Clinically active heart disease including prolonged QTc or prolonged PR interval, or history of arrhythmias
- On immunosuppressive or other anti-leukemic therapy, excluding patients receiving glucocorticoids for management of circulating blast count or patients on a stable dose (\<20mg/m2/day prednisone or equivalent) of systemic or topical glucocorticoid therapy with ≤ Grade 1 GvHD or tapering dose of calcineurin inhibitor
- Patients with known bleeding diathesis or prothrombin time (PT) or aPTT \>1.5 x ULN or fibrinogen \<0.5 x LLN
- Receiving prophylactic use of hematopoietic colony stimulating factors
- Known history of infection with human immunodeficiency virus (HIV) or chronic infection with hepatitis B virus (HBsAg positive) or hepatitis C virus (anti-HCV positive)
- Being actively treated for another concurrent malignancy
- Pregnant or nursing females;
- Male patients not willing to use a condom
- Uncontrolled intercurrent illness including, but not limited to uncontrolled infection, significant graft-versus-host-disease (GvHD) (Grade 2-4), or psychiatric illness/social situations that would limit compliance with study requirements
- Patients who are concurrently receiving strong inducers/inhibitors of CYP3A
- Patients with known history of Trisomy 21 (Down Syndrome), history of congenital immunodeficiency or inherited marrow failure disorder.
- Patients with known bleeding diathesis, or PT (Prothrombin time) or aPTT (activated partial thromboplastin time) \> 1.5x ULN or \<0.5x LLN.
