Are you eligible to participate in this study?

You may be eligible for this study if you meet the following criteria:

  • Conditions: Acute myeloid leukemia
  • Age: Between 18 - 100 Years
  • Gender: Male or Female

Inclusion Criteria:

  1. Male or female patient 18 years of age with newly diagnosed, histologically confirmed, AML including de novo, secondary to antecedent hematologic disorders, or treatment-related disease with intermediate or unfavorable-risk cytogenetics
  2. Unable to receive intensive chemotherapy regimens at enrollment, based on one of the
    following
  3. Age 75 years, or

II. Age < 75 years with at least 1 of the following co-morbidities:

  1. An ECOG performance status of 2
  2. Clinically significant cardiovascular disease defined as:
  3. Left ventricular ejection fraction (LVEF) 50%, measured within 3 months prior to Day 1 confirmed by ECHO/MUGA ii. Congestive heart failure requiring medical therapy iii. Chronic stable angina requiring medical therapy iv. Prior cerebrovascular accident with sequelae c. Clinically significant pulmonary disease defined as: i. Forced expiratory volume in 1 second (FEV1) 65% of expected ii. Lung diffusing capacity for carbon monoxide (DLCO) 65% of expected Confirmed by pulmonary tests. d. Diabetes mellitus with symptomatic end-organ damage (e.g., retinopathy, nephropathy, neuropathy, vasculopathy) e. Autoimmune inflammatory conditions (e.g., rheumatoid arthritis, systemic lupus erythematous, inflammatory bowel disease, or similar) requiring chronic disease modifying therapy (e.g., etanercept, adalimumab, infliximab, rituximab, methotrexate, or similar) f. Class III obesity defined as a Body Mass Index (BMI) > 40 kg/m2 g. Renal impairment defined as serum creatinine > 1.3 mg/dL (> 115 mol/L) or creatinine clearance <70 ml/min h. Clinically significant cognitive impairment defined as requiring medical therapy and/or assistance with activities of daily living
  4. 20% blasts in bone marrow
  5. Peripheral white blood cell (WBC) count 30,000/L For cyto-reduction, hydroxyurea is allowed during screening and up to Cycle 1, Days 1-14, to reduce WBC count to < 30,000 L prior to Day 1. After Cycle 1, Day 14, hydroxyurea is prohibited.
  6. ECOG performance status 2
  7. Adequate organ function as evidenced by the following laboratory findings:
  8. Total bilirubin 2 upper limit of normal (ULN) or < 3 x ULN for patients with Gilbert-Meulengracht Syndrome
  9. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) 2.5 ULN
  10. Serum creatinine 1.5 ULN according to institutional standards or creatinine clearance 50 mL/min
  11. QT-interval corrected according to Fridericia's formula (QTcF) 450 ms on electrocardiogram (ECG) at Screening
  12. Male patient who is surgically sterile, or male patient who is willing to agree to remain completely abstinent (refrain from heterosexual intercourse) or who use barrier contraceptive measures and agree to refrain from donating sperm during the entire study treatment period
  13. Female patient who is of childbearing potential willing to use adequate contraceptive measures while participating on study, OR willing to completely abstain from heterosexual intercourse during the entire study treatment period
  14. Female patient who is of childbearing potential must have a negative serum pregnancy test result within 3 weeks prior to starting study drugs.
  15. Willing to provide voluntary written informed consent before performance of any study related procedure not part of normal medical care
  16. Willing and able to understand the nature of this study and to comply with the study and follow-up procedures.

Exclusion Criteria:

  1. Able to receive intensive induction chemotherapy
  2. AML-associated inv(16)/t(16;16)/del(16q), t(15;17) (i.e. promyelocytic leukemia) with/without secondary aberrations; t(8;21) lacking del (9q) or complex karyotypes
  3. Presence of an active malignant disease within the last 12 months, with the exception of adequately treated cervical cancer in-situ, non-melanoma skin cancer and superficial bladder tumors (Ta [non-invasive tumor], Tis [carcinoma in situ] and T1 [tumor invades lamina propria]). Other malignancies may be considered after consultation with the Medical Monitor
  4. Life-threatening illnesses other than AML, uncontrolled medical conditions or organ system dysfunction that, in the Investigator's opinion, could compromise the patient's safety or put the study outcomes at risk
  5. Uncontrolled arrhythmias; any Class 3-4 cardiac diseases as defined by the New York Heart Association (NYHA) functional classification
  6. Evidence of AML central nervous system (CNS) involvement
  7. Previous chemotherapy for AML except for the following, which are allowed:
  8. Hydroxyurea for cytoreduction
  9. One course of hypomethylating agent therapy (i.e.; up to 7 doses of azacitidine or 3-5 days of decitabine) within 30 days prior to enrollment (Day 1)
  10. Use of experimental drugs 30 days prior to screening
  11. Received prior HDAC inhibitor therapy
  12. Received prior treatment with a hypomethylating agent, except as allowed in Exclusion Criterion 7.b
  13. Known hypersensitivity to any components of pracinostat, azacitidine, or mannitol
  14. History of human immunodeficiency virus (HIV) or an active and uncontrolled infection with hepatitis C virus (HCV) or hepatitis B virus (HBV)
  15. Gastrointestinal (GI) tract disease that causes an inability to take oral medication, malabsorption syndrome, or a requirement for IV alimentation; prior surgical procedures affecting absorption; or uncontrolled inflammatory GI disease (e.g., Crohn's disease, ulcerative colitis)
  16. Any disease(s), psychiatric condition, metabolic dysfunction, or findings from a physical examination or clinical laboratory test result that would cause reasonable suspicion of a disease or condition, that contraindicates the use of pracinostat and/or AZA, that may increase the risk associated with study participation, that may affect the interpretation of the results, or that would make the patient inappropriate for this study
