Outcome Measures
Primary Outcomes (1)
Percentage of Participants With Treatment-emergent Adverse Events (TEAEs) by Severity
An adverse event (AE) was defined as any untoward medical occurrence in a patient or clinical trial participant administered a medicinal product and which does not necessarily have a causal relationship with this treatment. TEAEs were defined as AEs with an onset date on or after the first dose of brexpiprazole. They are all adverse events that started after start of 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 therapy. Adverse events were graded on a 3-point scale. The intensity of an adverse experience was defined as follows: 1 = Mild: Discomfort noticed, but no disruption to daily activity, 2 = Moderate: Discomfort sufficient to reduce or affect normal daily activity, and 3 = Severe: Inability to work or perform normal daily activity.
From first dose through 30 days after last dose of study drug (Up to approximately Week 16)
Study Arms (2)
Prior Brexpiprazole
EXPERIMENTALParticipants who received brexpiprazole in a previous double-blind phase 3 study (Trial 331-14-213 {NCT03548584}), received the same dose of brexpiprazole \[2 or 3 milligrams (mg)\], once daily (QD), orally, as they received during the previous study, for up to 12 weeks with dose adjustment.
Prior Placebo
EXPERIMENTALParticipants who received placebo in a previous double-blind phase 3 study (Trial 331-14-213 {NCT03548584}), received brexpiprazole following a titration schedule, to gradually increase their dose from 0.5 mg QD, in the starting to 2 or 3 mg QD, orally, for up to 12 weeks with dose adjustment.
