ABSTRACT
UNLABELLED Anxious depression, defined as major depressive disorder (MDD) accompanied by high levels of anxiety, seems to be difficult to treat with traditional antidepressant monotherapy. The purpose of this study was to assess the efficacy of ziprasidone monotherapy in patients with anxious depression versus non-anxious depression. One hundred and twenty outpatients were enrolled in a 12-week study that was divided into two 6-week periods according to the sequential parallel comparison design. Patients were randomized in a 233 multi-ratio to receive ziprasidone for 12 weeks, placebo for 6 weeks, followed by ziprasidone for 6 weeks, or placebo for 12 weeks. Efficacy was measured according to the 17-item Hamilton Depression Rating Scale (HRDS-17), Quick Inventory of Depressive Symptomatology Self-Rated (QIDS-SR). Anxious depression was defined as a score of ≥7 on the HDRS-17 anxiety/somatization subscale. In phase I and II, ziprasidone monotherapy led to no significant changes compared with placebo on the HDRS-17 and QIDS-SR scores in patients with both anxious and non-anxious depression. In the pooled analysis, ziprasidone monotherapy also produced no significance on the HDRS-17 (Z = 0.25, P = 0.80) and QIDS-SR (Z = 0.43, P = 0.67) in patients with anxious depression. In conclusion, treatment with ziprasidone monotherapy may produce no significant improvement compared with placebo in patients with in anxious depression. TRIAL REGISTRATION ClinicalTrials.gov identifier NCT00555997.
