Brief Summary:
The objectives of this study are to evaluate the effect of the timing of a moderate-fat meal on the single dose pharmacokinetics of entinostat and to evaluate the safety and tolerability of entinostat under fed and fasting conditions in healthy adult subjects.

Condition or disease Intervention/treatment Phase
Volunteers Healthy Volunteers Human Volunteers Normal Volunteers Drug: Entinostat Phase 1

Detailed Description:

This is a 2-stage food effect (timing of the meal) study. A total of 48 subjects will be dosed if Stage 2 is conducted.

Stage 1 will be conducted as an open-label, randomized, 2-way crossover study. On Day 1 of each period, subjects will receive a single, oral dose of entinostat under fasting or fed conditions.

If preliminary results in Stage 1 indicate that the timing of a meal exhibits significant effect on the bioavailability of entinostat, then Stage 2 will be conducted which will investigate the effect of a meal either before or after dosing of entinostat on entinostat PK.

Stage 2 will be conducted as an open-label, randomized, 3-way crossover study. On Day 1 of each period, subjects will receive a single, oral dose of entinostat under fasting or fed conditions.

Primary Outcome Measures :
  1. AUC0-t (area under the concentration-time curve, from time 0 to the last observed non-zero concentration (t) for entinostat under fed and fasting conditions [ Time Frame: Pre-dose through Day 22 ]
  2. AUC0-inf (area under the concentration-time curve, from time 0 extrapolated to infinity) for entinostat under fed and fasting conditions [ Time Frame: Pre-dose through Day 22 ]
  3. Cmax (maximum observed concentration) of entinostat under fed and fasting conditions [ Time Frame: Pre-dose through Day 22 ]
  4. AUC%extrap (percent of AUC0-inf extrapolated) of entinostat under fed and fasting conditions [ Time Frame: Pre-dose through Day 22 ]
  5. Tmax (time to reach maximum observed concentration) of entinostat under fed and fasted conditions [ Time Frame: Pre-dose through Day 22 ]
  6. Kel (apparent terminal elimination rate constant) of entinostat under fed and fasted conditions [ Time Frame: Pre-dose through Day 22 ]
  7. T1/2 (apparent terminal elimination half-life) of entinostat under fed and fasted conditions [ Time Frame: Pre-dose through Day 22 ]
  8. Changes from baseline in physical exam [ Time Frame: Baseline through Day 1 ]
  9. Changes from baseline in vital signs [ Time Frame: Baseline through Day 22 ]
  10. Changes from baseline in ECG results [ Time Frame: Baseline through Day 22 ]
  11. Changes from baseline in adverse events [ Time Frame: Baseline through 14 days after last sample collection ]
  12. Changes from baseline in clinical laboratory tests [ Time Frame: Baseline through Day 1 ]
