This research is being done to help us learn how to best use new drugs which may be active against acute myeloid leukemia (AML). Two study drugs will be tested: 5AC (5-azacitidine) and entinostat. 5AC improves blood counts in 50 - 60% of patients with MDS and has also shown promise in AML. Entinostat has undergone early testing in patients with MDS and AML. It has decreased the blast count in some patients' blood and bone marrow and has improved the blood counts in some patients. The combinations of these two classes of drugs are well tolerated and appear to work well together in laboratory tests.

A recent study at JHU administered 5AC and entinostat in an overlapping schedule to patients with MDS, CMMoL, and AML. The impressive results from this study have led to another phase II trial to further examine this drug combination versus 5AC alone in these patients. In this study, we want to see how the timing of when 5AC and entinostat are given affects the magnitude of the disease response.

Primary Outcome Measures:
  • To estimate the major response rate in patients with AML who are > 60 years old and unable to tolerate or decline cytotoxic chemotherapy or patients who have relapsed despite one prior regimen.
  • To estimate the overall response rate following treatment in patients with AML > 60 years old who are unable to tolerate or decline cytotoxic chemotherapy or those who have relapsed despite one prior regimen.

Secondary Outcome Measures:
  • To identify changes in gene promoter methylation and gene expression in response to combination therapy and compare the dynamics and kinetics of these alterations in promoter methylation and gene re-expression in the two different dosing schedules.
  • To evaluate the effect of entinostat on the induction of hyperacetylation of histones from peripheral blood and/or bone marrow samples.
  • To evaluate changes in DNA damage in response to combination therapy using gammaH2AX determination by western blotting.
  • To evaluate the pharmacodynamics of 5AC and entinostat when given at either dosing schedule and to evaluate these in relation to pharmacokinetic and clinical outcomes.
  • To evaluate duration of response.

Estimated Enrollment: 108
Study Start Date: July 2011
Estimated Primary Completion Date: July 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: A
Arm A will be given an overlapping schedule of drugs with 5AC given at 50mg/m2 subcutaneously daily for 10 days on days 1 - 10 of a 28 day cycle and entinostat given at a flat dose of 8 mg orally on days 3 and 10.
Drug: Entinostat
Other Name: MS275
Drug: 5-azacitidine
Other Name: 5AC
Experimental: B
In Arm B the agents will be administered sequentially with 5AC given at 50mg/m2 subcutaneously daily for 10 days on days 1 - 10 of a 28 day cycle followed by entionostat at a 8 mg flat dose on days 10 and 17.
Drug: Entinostat
Other Name: MS275
Drug: 5-azacitidine
Other Name: 5AC


Ages Eligible for Study:   60 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. One of the following:

    Untreated AML in (de novo or treatment related) patients of age > 60 years in the following categories:

    • Medical conditions that compromise the ability to give cytotoxic chemotherapy as the primary modality.
    • Patients who decline cytotoxic chemotherapy.

    Patients with AML of age ≥ 60 years who have relapsed despite one prior regimen

  2. ECOG performance status 0, 1, or 2 (see Appendix A).
  3. Age > 60 years
  4. Patients must not have untreated active infections at the time of study entry.
  5. Normal organ function as defined below:

    • Creatinine < 2 mg/dl.
    • Total serum bilirubin within institutional limits unless due to hemolysis, Gilbert's syndrome, or ineffective erythropoiesis.
    • AST(SGOT)/ALT(SGPT) ≤2.5 X institutional upper limit of normal.
  6. Life expectancy of at least three months.
  7. Patients must be informed of the investigational nature of the treatment, results that might be expected, and potential toxicities. They must be able to understand and give informed written consent according to federal and institutional guidelines.
  8. Declined or ineligible for potentially curative options such as allogeneic stem cell transplant.
  9. No chemotherapy or study drugs for >3 weeks prior to starting study.
  10. Women of childbearing potential should be advised to avoid becoming pregnant and men should be advised to not father a child while receiving treatment. All men and women of childbearing potential must use acceptable methods of birth control throughout the study as described below:

Females of childbearing potential: Recommendation is for 2 effective contraceptive methods during the study. Adequate forms of contraception are double-barrier methods (condoms with spermicidal jelly or foam and diaphragm with spermicidal jelly or foam), oral, depo provera, or injectable contraceptives, intrauterine devices, and tubal ligation.

Male patients with female partners who are of childbearing potential: Recommendation is for male and partner to use at least 2 effective contraceptive methods, as described above, during the study or to abstain.

Exclusion Criteria

  1. Any of the Following:

    • Treatment for AML, including hematopoietic growth factors, < 3 weeks prior to study registration. Exception: Hydroxyurea may be administered to patients with WBC > 30,000/µL (see Section 8)
    • Radiotherapy < 4 weeks prior to study registration
    • Failure to recover (to < grade 1) from all adverse events associated with prior therapy.
    • Valproic acid < 2 weeks prior to study registration.
    • Hypersensitivity to azacytidine, deoxyazacytidine, mannitol, entinostat or components of the entinostat tablet
    • Any advanced malignant hepatic tumor(s)
  2. Prior therapy with demethylating agents for leukemia treatment within the last year.
  3. Clinical evidence of CNS or pulmonary leukostasis, disseminated intravascular coagulation, or CNS leukemia.
  4. Serious or uncontrolled medical conditions.
  5. Concurrent use of any other investigational agents.
  6. Known HIV-positive patients.
  7. Pregnancy or breast feeding
  8. Male and female patients who are fertile who do not agree to use an effective barrier methods of birth control (i.e. abstinence) to avoid pregnancy during the study and for a minimum of 30 days after study treatment.
