Notes: TEAEs occurring in ≥5% of participants in any group after the conversion phase for the three phase III brexpiprazole studies focusing on the efficacy or safety of brexpiprazole in the treatment of adults with schizophrenia were included in this table. Akathisia occurred at a rate <5% in safety study 1, but was included in this table because akathisia had occurred at rates of >5% in previous placebo-controlled brexpiprazole studies. Also included are safety data pertaining to weight gain ≥7% total body weight from enrollment to last observation and suicidal ideation/behavior.

Abbreviations: TEAEs, treatment-emergent adverse events; NR, not reported.
