Primary Outcome Measures
NameTimeMethod
Participants With Adverse Events (AEs).After the Informed Consent Form (ICF) was signed, through Follow up 30 (+2) days after last visit

An AE was defined as any new medical problem, or exacerbation of an existing problem, experienced by a participant while enrolled in the trial, whether or not it was considered drug-related by the physician. The severity was assessed as mild, moderate, or severe. A treament-emergent AE (TEAE) was defined as any AE that started after start of open-label brexpiprazole; or if the event was continuous from baseline and was worsening, serious, study drug-related, or resulted in death, discontinuation, interruption, or reduction of study drug.

Secondary Outcome Measures
NameTimeMethod
Change From Baseline in Clinical Global Impression - Severity of Illness (CGI-S) Scale Score.Week 1, 2, 4, 6, 8, 14, 20, 26, 32, 38, 44, 52 and 52 (last-observation-carried-forward [LOCF])

The CGI-S is a 7-point scale from 1 through 7. The items on CGI-S scale are: 0 = not assessed, 1 = normal, not at all ill, 2 = borderline mentally ill, 3 = mildly ill, 4 = moderately ill, 5 = markedly ill, 6 = severely ill, 7 = among the most extremely ill participants. The score 0 (= not assessed) was set to missing.

Mean Clinical Global Impression - Improvement (CGI-I) Scale Score.Week 1, 2, 4, 6, 8, 14, 20, 26, 32, 38, 44, 52 and 52 (LOCF)

The items on CGI-I scale are 0 = not assessed, 1 = very much improved, 2 = much improved, 3 = minimally improved, 4 = no change, 5 = minimally worse, 6 = much worse, 7 = very much worse. The score of 0 (= not assessed) was set to missing. The CGI-I is therefore a 7-point scale from 1 through 7. CGI improvement was compared to the participants condition at Baseline.
