VRAYLAR Significantly Improved Overall Schizophrenia Symptoms1,13-15*

It is unknown if the statistically significant differences observed at time points earlier than Week 6 represent clinically relevant treatment effects.
Maximum recommended dose of VRAYLAR is 6 mg/day. Doses above 6 mg daily did not appear to have additional benefit over lower doses and a dose-related increase in certain adverse reactions was observed.1
Three 6-week, randomized, double-blind, placebo-controlled studies evaluating the efficacy and safety of VRAYLAR in adult patients (18-60 years old) with acute exacerbation of schizophrenia, based on DSM-IV-TR criteria. The primary statistical analyses were conducted using the LOCF approach for Study 1 and an MMRM approach for Study 2 and Study 3. In each study, the primary endpoint was the LS mean change from baseline in PANSS total score at the end of Week 6.1,13-15
*The approval of VRAYLAR for the treatment of schizophrenia was based on the change from baseline in total score, not individual symptom measurement, on the PANSS.1

Long-term maintenance treatment of schizophrenia in adults was assessed in a 92-week study of VRAYLAR1,16
Following a 20-week, open-label phase on a stable dose of VRAYLAR, patients were randomized to VRAYLAR 3–9 mg/day or placebo for a 72-week, double-blind phase.1,16

Patients remaining on VRAYLAR had a 48% lower risk of relapse vs placebo
[(hazard ratio=0.52; 95% CI: 0.33, 0.82) P=0.0039]
After one year, 35% of VRAYLAR patients relapsed vs 56% of placebo patients
Observed incidence of relapse was similar until approximately Week 6 (Day 44)
A long-term, 92-week, randomized withdrawal study that included a 20-week open-label phase and a 72-week double-blind placebo-controlled phase. Adult patients who met DSM-IV-TR criteria for schizophrenia (n=765) and who were clinically stable following 20 weeks of open-label VRAYLAR at doses of 3–9 mg/day were then randomized to receive either placebo (n=99) or VRAYLAR (n=101) at the same dose for up to 72 weeks in the double-blind phase. The primary endpoint was time to relapse.1,16
Relapse in the withdrawal study was defined as meeting any one of the following criteria: hospitalization due to worsening of schizophrenia, increase in the PANSS total score by ≥30%, increase in the PANSS total score by ≥2 points, deliberate self-injury, aggressive or violent behavior, clinically significant suicidal or homicidal ideation, or score >4 on one or more of the following PANSS items: delusions, conceptual disorganization, hallucination, suspiciousness or persecution, hostility, uncooperativeness, or poor impulse control.1,16
Recommended dose range of VRAYLAR is 1.5-6 mg/day. Doses above 6 mg daily did not appear to have additional benefit over lower doses and a dose-related increase in certain adverse reactions was observed.1
