  Purpose

Arm 1:

Primary Objective:

• To determine the safety and tolerability of multiple ascending, supratherapeutic doses of HPN-100.

Arm 2:

Primary Objective:

• To assess the effects of steady-state levels of HPN-100 metabolites (4 phenylbutyric acid [PBA], phenylacetic acid [PAA], and phenylacetylglutamine [PAGN]) on 12-lead electrocardiogram (ECG) parameters in healthy male and female subjects with the primary endpoint being the time-matched change from baseline in the QT interval corrected for heart rate (HR) based on an individual correction method (QTcI).
