Brief Summary:
To identify the maximum tolerated dose (MTD) of oral azacitidine on different treatment schedules in Japanese subjects with hematological neoplasms

Condition or disease Intervention/treatment Phase
Myelodysplastic Syndromes Chronic Myelomonocytic Leukemia Acute Myeloid Leukemia Multiple Myeloma Non-Hodgkin Lymphoma Hodgkin Lymphoma Drug: Oral azacitidine Phase 1

Detailed Description:
This is a phase 1, multicenter, open-label, dose-escalation study that will evaluate the maximum tolerated dose (MTD), safety, pharmacokinetics, and preliminary efficacy of CC-486 in Japanese subjects with hematological neoplasms including myelodysplastic syndromes (MDS), chronic myelomonocytic leukemia (CMML), acute myeloid leukemia (AML), multiple myeloma (MM), non-Hodgkin lymphoma (NHL), or Hodgkin lymphoma (HL). A standard phase 1 design for MTD determination, an open label, dose ascending, "3 + 3" design, is adopted in this study. This study consists of screening phase, MTD determination phase, and treatment phase. Each subject continues study treatment until documentation of progressive disease or discontinuation of study treatment for any reason. Originally only MDS subjects were targeted and the MTD of CC-486 when administered once daily (QD) for 21 days in a 28-day cycle would be evaluated in this study. Currently CC-486 is being clinically developed with both 14-day and 21-day dosing schedules in various diseases. This study was suspended to amend protocol to evaluate the MTD on these different dosing schedule in larger population. This study was re-opened after amended protocol was approved by institutional review board at study site.

Study Start Date : July 2013
Actual Primary Completion Date : July 2015
Actual Study Completion Date : July 2015


Arm Intervention/treatment
Experimental: Oral azacitidine Drug: Oral azacitidine
100 mg to 300 mg oral azacitidine once daily for 14 days or 21 days of the initial 28-day cycle
Other Name: CC-486




Primary Outcome Measures :
  1. Dose limiting toxicities [ Time Frame: For 28 days ]
    Number of subjects experiencing dose limiting toxicity during the first 28-day cycle


Secondary Outcome Measures :
  1. Number of participants with adverse events. [ Time Frame: Up to 4 years ]
    Number of participants with adverse events. An AE is any noxious, unintended, or untoward medical occurrence that may appear or worsen in a subject during the course of a study. It may be a new intercurrent illness, a worsening concomitant illness, an injury, or any concomitant impairment of the subject's health, including laboratory test values (as specified by the criteria below), regardless of etiology.

  2. Pharmacokinetics - Cmax [ Time Frame: On day 1 and day 8 ]
    Maximum observed concentration in plasma

  3. Pharmacokinetics - Tmax [ Time Frame: On day 1 and day 8 ]
    Observed time to first maximum plasma concentration

  4. Pharmacokinetics - AUCt [ Time Frame: On day 1 and day 8 ]
    Area under the plasma concentration-time curve from time zero to the last quantifiable time point, calculated by the linear trapezoidal rule

  5. Pharmacokinetics - AUC Zero to Infinity [ Time Frame: On day 1 and day 8 ]
    Area under the plasma concentration-time curve from time zero to infinity, calculated by the linear trapezoidal rule and extrapolated to infinity will be calculated according to the following equation: AUC∞ = AUCt + (Ct/λz), where Ct is the last quantifiable concentration If the percentage of AUC extrapolated is ≥ 25%, AUC∞ will not be reported.

  6. Pharmacokinetics - AUCext% [ Time Frame: On day 1 and day 8 ]
    Percentage of AUC∞ due to extrapolation from the time from the last quantifiable concentration to infinity, calculated as (AUC∞ - AUCt) / AUC∞ ×100

  7. Pharmacokinetics - Terminal Phase [ Time Frame: On day 1 and day 8 ]
    Terminal phase rate constant, determined by linear regression of the terminal points of the log-linear plasma concentration-time curve Visual assessment may be used to identify the terminal linear phase of the concentration versus time profile. A minimum of three data points will be used for calculation. λz will not be estimated if the terminal phase of the log-concentration versus time profile does not exhibit a linear decline phase, or if the regression coefficient < 0.8.

  8. Pharmacokinetics - Terminal Half-Life [ Time Frame: On day 1 and day 8 ]
    Terminal phase half-life, will be calculated according to the following equation: t1/2 = 0.693/λz

  9. Pharmacokinetics - Total Clearance [ Time Frame: On day 1 and day 8 ]
    Apparent total clearance, calculated as Dose/AUC∞

  10. Pharmacokinetics - Volume of distribution [ Time Frame: On day 1 and day 8 ]
    Apparent volume of distribution will be calculated according to the equation: Vz/F = (CL/F)/λz

  11. Pharmacokinetics - Aet [ Time Frame: On day 1 and day 8 ]
    Cumulative amount excreted from time zero to time t (ng), calculated as the summation of the amounts (Aet, product of urine volume and urine concentration) excreted in subsequent collection intervals

  12. Pharmacokinetics - fet [ Time Frame: On day 1 and day 8 ]
    Cumulative fraction of dose excreted in the urine from time zero to time t (%), calculated as Ae t divided by dose

  13. Pharmacokinetics - Renal Clearance [ Time Frame: On day 1 and day 8 ]
    Renal clearance (mL/min), calculated as Aet divided by AUCt

  14. Investigator's response assessment [ Time Frame: Up to 4 years ]
    Number of participants who demonstrate response by investigator's assessment based on International Working Group (IWG) criteria Myelodysplastic Syndrome (MDS), Chronic myelomonocytic Leukemia (CMML) and Acute Myeloid (AML), IMWG criteria for Multiple Myeloma (MM), and modified Cheson 2007 criteria for Non-Hodgkin's Lymphoma (NHL) or Hodgkin's Lymphoma (HL)
