330 participants in 3 patient groups

De Novo

Experimental group

Description:

De novo participants (those who did not participate in protocol (CN138-178 \[NCT00332241\] or CN138-179 \[NCT00337571\]) assigned to open-label aripiprazole (oral tablet), flexibly dosed (2 to 15 mg/day) taken once daily, started at 2 mg/day on Day 1. Target daily dose was 5 mg, 10 mg, or 15 mg; maximum dose, regardless of weight, was 15 mg. Dose increases were incremental (dose levels are 2 mg, 5 mg, 10 mg, and 15 mg), occurring no more often than every 4 days, and were based on assessment of efficacy and tolerability at the current dose. The dosage could be adjusted downward if the patient experienced intolerance at any time to the current dose.

Treatment:

Drug: Aripiprazole

Rollover Placebo

Experimental group

Description:

Participants who completed participation in protocol (CN138-178 \[NCT00332241\] or CN138-179 \[NCT00337571\]) on placebo treatment and continued to meet all of the inclusion criteria and none of the exclusion criteria. Assigned in this study to open-label aripiprazole (oral tablet), flexibly dosed (2 to 15 mg/day) taken once daily, started at 2 mg/day on Day 1. Target daily dose was 5 mg, 10 mg, or 15 mg; maximum dose, regardless of weight, was 15 mg. Dose increases were incremental (dose levels are 2 mg, 5 mg, 10 mg, and 15 mg), occurring no more often than every 4 days, and were based on assessment of efficacy and tolerability at the current dose. The dosage could be adjusted downward if the patient experienced intolerance at any time to the current dose.
