Outcome Measures
Primary Outcomes (5)
Percentage of Participants Able to Tolerate Maximum Dose Level
Dose toleration was defined as the following: during the course of the study the participant does not experience any untoward events or potentially clinically significant changes from baseline in laboratory values, vital signs, electrocardiogram (ECG) tracings, or Extrapyramidal symptoms (EPS) ratings (evaluation of parkinsonism, dyskinesia, and akathisia) that are assessed as possibly related to the drug, and would warrant adjustment or discontinuation of the study drug.
14 Days
Number of Participants With Adverse Events, Serious Adverse Events and Discontinuation Due to Adverse Event as a Measure of Safety
An adverse event was considered any unfavorable and unintended sign, symptom, or disease associated with the use of the study drug, whether or not considered related to the study drug. Preexisting conditions that worsened during the study were reported as adverse events. A serious adverse event is any experience that suggests a significant hazard, contraindication, side effect or precaution that: results in death, is life-threatening, required in-patient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect or is medically significant.
57 days
Aripiprazole Maximum Steady State Plasma Concentration (Css,Max)
Blood samples were collected pre-dose and 1, 2, 3, 4, 6, 8, 10, and 24 hours post dose on Day 14 and were analyzed by a validated High-Performance Liquid Chromatography/ Mass Spectrometry (HPLC-MS/MS) method for aripiprazole. Css,max value was determined using observed data.
Pre-dose and 1 to 24 hours post-dose on Day 14
Aripiprazole Time to Maximum (Peak) Plasma Concentration (Tmax)
Blood samples were collected pre-dose and 1, 2, 3, 4, 6, 8, 10, 24 and 25 hours post dose on Day 14 and were analyzed by a validated High-Performance Liquid Chromatography/ Mass Spectrometry (HPLC-MS/MS) method for aripiprazole. Tmax value was determined using observed data.
Pre-dose and 1 to 25 hours post-dose on Day 14
Aripiprazole Area Under the Concentration-Time Curve at Steady-State (AUCτ)
Blood samples were collected pre-dose and 1, 2, 3, 4, 6, 8, 10, and 24 hours post-dose on Day 14 and were analyzed by a validated High-Performance Liquid Chromatography/ Mass Spectrometry (HPLC-MS/MS) method for aripiprazole. Values of AUCτ were estimated using the linear trapezoidal rule to the actual time of the 24-hour sample.
Pre-dose and 1 to 24 hours post-dose on Day 14

Study Arms (3)
aripiprazole 20 mg
EXPERIMENTALParticipants were administered aripiprazole tablets to be taken orally once daily starting at a dose of 2 mg increased over 12 days to achieve a dose level of 20 milligrams (mg). Following the dose-escalation phase, participants entered the fixed-dose phase and received 20 mg for 14 days.
aripiprazole 25 mg
EXPERIMENTALParticipants were administered aripiprazole tablets to be taken orally once daily starting at a dose of 2 mg increased over 12 days to achieve a dose level of 25 milligrams (mg). Following the dose-escalation phase, participants entered the fixed-dose phase and received 25 mg for 14 days.
aripiprazole 30 mg
EXPERIMENTALParticipants were administered aripiprazole tablets to be taken orally once daily starting at a dose of 2 mg increased over 12 days to achieve a dose level of 30 mg. Following the dose-escalation phase, participants entered the fixed-dose phase and received 30 mg for 14 days.
Interventions
Aripiprazole tablets ranging from 2 to 30 mg to be taken orally once a day.

- Use of any prescription medication not specifically approved by the medical monitor or study director.
- A positive hepatitis C antibody test.
- Females who were pregnant or lactating.
- Subjects who had participated in any clinical trial within 1 month prior to enrollment, or in a clinical trial involving psychotropic medication within 6 months prior to the end of baseline, unless permission was obtained from the sponsor.
