Alternative 10 mg/mL Liquid Formulation of ACY 1215 (Ricolinostat) in Healthy Subjects

Subjects will be confined to the Clinical Research Unit (CRU) from the time of Check-in (Day -1) to Day 10. Predose blood and urine samples will be obtained prior to each ACY-1215 administration. Following administration of ACY-1215 in each period, blood and urine samples will be collected at specified timepoints or intervals through 24 hours postdose for the determination of the PK of a single oral dose of ACY-1215. Subjects will be discharged from the CRU on Day 10, following the completion of the last PK collection and successful completion and evaluation of discharge safety tests. Subjects will return to the clinic for a Follow-up visit 5 to 7 days after the last dose of ACY-1215 (Days 14 to 16) for additional safety evaluations.
