WEIGHT CHANGE AND METABOLIC EFFECTS OF ASENAPINE IN PLACEBO- OR OLANZAPINE-CONTROLLED STUDIES

Methods Data were from pooled asenapine trials that used placebo (1748 patients; duration: 1−6 wk) and/or olanzapine (3430 patients; duration, 3−>100 wk) controls. Asenapine doses were 5 or 10 mg BID (2–20 mg BID in 2 studies); olanzapine doses were 5–20 mg QD. Post hoc inferential analyses based on ANOVA assessed change from baseline weight, body mass index, and fasting lipid and glucose levels. Results Table 1 summarizes the results. Discussion These post hoc pooled analyses support published reports and suggest asenapine was associated with moderate weight gain and increased fasting triglyceride and glucose levels vs placebo, but lower propensity for weight gain or increased serum lipids (ie, triglycerides, low-density lipoprotein, and cholesterol) vs olanzapine.
