In a third study by Findling et al5 subjects were randomized to flexible oral doses of ziprasidone (40–160 mg/day, based on weight) or placebo. The primary endpoint was a change from baseline on the Brief Psychiatric Rating Scale-Anchored (BPRS-A). A 6-week RCT was followed by a 26-week, open-label extension study. A planned interim analysis for the primary endpoint in the RCT resulted in early termination of both studies. Treatment of EOS with ziprasidone failed to differentiate itself from the placebo group; however, ziprasidone was generally well tolerated, with a neutral weight and metabolic profile. Somnolence and extrapyramidal disorders were the most common adverse events compared with the placebo group (19.7% versus 6.7% and 11.4% versus 1.1%, respectively).
