Long-term Safety and Efficacy Data
In a year long, double-blind, randomized study of 1200 patients with schizophrenia or schizoaffective disorder treated with asenapine or olanzapine (3:1 randomization), the safety evaluation showed that the overall rates of AEs were similar for the asenapine 5-10 mg BID arm and olanzapine 10-20 mg QD arm (drug-related AEs, 60 percent and 61 percent respectively; withdrawal due to serious adverse events, 6.3 percent and 6.8 percent, respectively). On efficacy measures, improvements in PANSS total score were greatest for both asenapine and olanzapine within the first six to eight weeks of treatment and were maintained throughout the 52-week study period. In an exploratory secondary analysis, the between-group difference at 52 weeks favored olanzapine. Most commonly reported AEs (greater than or equal to 10 percent) in both treatment groups were insomnia, worsening psychotic symptoms, weight gain and depression.
Additional Asenapine Data Presentations
Additional asenapine data were presented in poster sessions during the meeting.
