Outcome Measures
Primary Outcomes (1)
Time From Baseline to the First Symptom Relapse During the Double-blind Phase
Relapse was defined as meeting ≥1 of the following criteria:1-Hospitalization due to worsening of condition;2-increase in Positive and Negative Syndrome Scale(PANSS) total score by ≥30% for participants,scored ≥50 or a ≥10-point increase for participants,scored \<50 at randomization;3-increase in Clinical Global Impressions-Severity(CGI-S) score by ≥2 points at Week 20;4-deliberate self-injury or aggressive behaviour;5-suicidal/homicidal ideation judged clinically significant by Investigator;6-score of \>4 on 1 or more of following PANSS items:P1,P2,P3,P6,P7,G8 or G14. Second assessment not performed based on Investigator discretion. PANSS is 30-item rating scale. Each item scored on 7-point scale. Total score ranges from 30 to 210. Lower score indicates fewer schizophrenic symptoms. CGI-S is 7-point scale,measures severity of participant's illness in comparison with others with same diagnosis. Lower score indicates less severe illness. 25th percentile for time to relapse was reported.
Up to 34 Weeks and Bi-Weekly thereafter until Week 92
Study Arms (3)
Cariprazine - Open-label Phase
EXPERIMENTALParticipants received 3, 6, or 9 mg cariprazine orally once a day for 6 weeks; the dose could be modified during this time. The cariprazine dose was fixed at 3, 6, or 9 mg for the last 14 weeks of this 20 week Open-label Phase.
Placebo - Double-blind Treatment Phase
EXPERIMENTALParticipants received placebo orally once a day for 26 to 72 weeks.
Cariprazine - Double-blind Treatment Phase
EXPERIMENTALParticipants received 3, 6, or 9 mg cariprazine orally once a day for 26 to 72 weeks
Interventions
Cariprazine was supplied as 1.5 mg capsules (batch numbers BN0009242 and BN00018595) and 3 mg capsules.
