AR-42 and Decitabine in Treating Patients With Acute Myeloid Leukemia
Phase I Study of AR-42 and Decitabine in Acute Myeloid Leukemia
This phase I trial studies the side effects and best dose of AR-42 when given together with decitabine in treating patients with acute myeloid leukemia. AR-42 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as decitabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving AR-42 together with decitabine may kill more cancer cells.
PRIMARY OBJECTIVES: I. To determine the biologic effective and tolerable dose (BETD) of AR-42 (histone deacetylase [HDAC] inhibitor AR-42) in combination with a 10 day schedule of decitabine in acute myeloid leukemia (AML) in adults (Stratum 1) and children (Stratum 2). II. To define the specific toxicities and the dose limiting toxicity (DLT) of AR-42 in combination with a 10 day schedule of decitabine in adults and children. SECONDARY OBJECTIVES: I. To describe biologic activity of the combination of AR-42 and decitabine (changes in micro ribonucleic acid [RNA] [miR]-29b expression; specificity protein 1 [Sp1], deoxyribonucleic acid [DNA] (cytosine-5-)-methyltransferase [DNMT]1, 3A and 3B, KIT and FMS-like tyrosine kinase 3 [FLT3] RNA and protein levels). II. To provide preliminary data for clinical response with the combination of AR-42 and decitabine in adults and in children. III. To provide preliminary data on correlation of biologic endpoints and clinical response (particularly miR-29b expression). OUTLINE: This is a dose-escalation study of HDAC inhibitor AR-42. INDUCTION THERAPY: Patients receive HDAC inhibitor AR-42 orally (PO) daily on days 1, 3, and 5 or 1, 3, 4, 5 and decitabine intravenously (IV) over 1 hour on days 6-15. Treatment repeats every 28 days for up to 3 courses in the absence of disease progression or unacceptable toxicity. MAINTENANCE THERAPY: Patients achieving complete remission (CR) or morphologic CR with incomplete blood count recovery (CRi) receive HDAC inhibitor AR-42 as in Induction Therapy and decitabine IV over 1 hour on days 6-10. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up periodically.

Description: INDUCTION THERAPY: Patients receive HDAC inhibitor AR-42 PO daily on days 1, 3, and 5 or 1, 3, 4, 5 and decitabine IV over 1 hour on days 6-15. Treatment repeats every 28 days for up to 3 courses in the absence of disease progression or unacceptable toxicity. MAINTENANCE THERAPY: Patients achieving CR or CRi receive HDAC inhibitor AR-42 as in Induction Therapy and decitabine IV over 1 hour on days 6-10. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Inclusion Criteria: - Adult patients (stratum 1) must be age >= 18 with relapsed or refractory acute myeloid leukemia (AML) or age >= 60 with previously untreated AML who are not candidates for or refuse standard/conventional induction chemotherapy (e.g. the 7+3 combination of cytarabine and an anthracycline); pediatric patients, age 3 to < 18 years (stratum 2) will be eligible with AML in second relapse or with refractory disease - Patients with secondary AML or therapy related disease (t-AML) are eligible - Patients who received decitabine or 5-azacitidine as prior treatment for myelodysplastic syndrome (MDS) (or AML) remain eligible for the dose escalation phase of the study; however, neither of these agents is permitted within 3 months of study entry; patients who have received prior decitabine or 5- azacitidine will be excluded from the expansion phase of the trial - If the patient has co-morbid medical illness, life expectancy attributed to this must be greater than 6 months - Performance status: Adults (>= 18 years) must be Eastern Cooperative Oncology Group (ECOG) performance status =< 2; pediatric patients (< 18 years) must be at least Lansky > 50% - Total bilirubin < 2.0 mg/dL - Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) < 2.5 X institutional upper limit of normal - Creatinine < 2.0 mg/dL (adults > 18 years); < 1.3 x upper limit normal for age (pediatric patients < 18 years) - New York Heart Association (NYHA) congestive heart failure (CHF) class II or better - The effects of decitabine and AR-42 on the developing human fetus at the recommended therapeutic dose are unknown; for this reason, both men and women must agree to use adequate contraception (barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; if the patient does not agree, the patient is not eligible; should a woman become pregnant or suspect she is pregnant while participating in the study, she should inform her treating physician immediately - Ability to understand and willingness to sign the written informed consent document - Patients must have recovered from the toxicity of prior therapy to less than grade 2 Exclusion Criteria: - Patients who have had chemotherapy or radiotherapy within 2 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study;
