Primary Outcome Measures:

Change From Baseline in QTcF at 0.5 Hours [ Time Frame: Baseline and 0.5 hours ] [ Designated as safety issue: Yes ]
The Fridericia correction of the QT interval (QTcF) was determined at each time point from five replicate measurements. The change from baseline in QTcF was calculated by subtracting the QTcF value at each timepoint from the QTcF baseline (predose) value.
Change From Baseline in QTcF at 1 Hour [ Time Frame: Baseline and 1 hour ] [ Designated as safety issue: Yes ]
Fridericia correction of the QT interval (QTcF) was determined at each time point from five replicate measurements. The change from baseline in QTcF was calculated by subtracting the QTcF value at each timepoint from the QTcF baseline (predose) value.
Change From Baseline in QTcF at 2 Hours [ Time Frame: Baseline and 2 hours ] [ Designated as safety issue: Yes ]
The Fridericia correction of the QT interval (QTcF) was determined at each time point from five replicate measurements. The change from baseline in QTcF was calculated by subtracting the QTcF value at each timepoint from the QTcF baseline (predose) value.
Change From Baseline in QTcF at 3 Hours [ Time Frame: Baseline and 3 hours ] [ Designated as safety issue: Yes ]
The Fridericia correction of the QT interval (QTcF) was determined at each time point from five replicate measurements. The change from baseline in QTcF was calculated by subtracting the QTcF value at each timepoint from the QTcF baseline (predose) value.
Change From Baseline in QTcF at 4 Hours [ Time Frame: Baseline and 4 hours ] [ Designated as safety issue: Yes ]
The Fridericia correction of the QT interval (QTcF) was determined at each time point from five replicate measurements. The placebo-corrected change from baseline in QTcF was calculated by subtracting the QTcF change from baseline for placebo at each timepoint from the QTcF change from baseline for vorinostat at each timepoint.
Change From Baseline in QTcF at 8 Hours [ Time Frame: Baseline and 8 hours ] [ Designated as safety issue: Yes ]
The Fridericia correction of the QT interval (QTcF) was determined at each time point from five replicate measurements. The change from baseline in QTcF was calculated by subtracting the QTcF value at each timepoint from the QTcF baseline (predose) value.
Change From Baseline in QTcF at 12 Hours [ Time Frame: Baseline and 12 hours ] [ Designated as safety issue: Yes ]
The Fridericia correction of the QT interval (QTcF) was determined at each time point from five replicate measurements. The change from baseline in QTcF was calculated by subtracting the QTcF value at each timepoint from the QTcF baseline (predose) value.
Change From Baseline in QTcF at 24 Hours [ Time Frame: Baseline and 24 hours ] [ Designated as safety issue: Yes ]
The Fridericia correction of the QT interval (QTcF) was determined at each time point from five replicate measurements. The change from baseline in QTcF was calculated by subtracting the QTcF value at each timepoint from the QTcF baseline (predose) value.
