Metyrapone as additive treatment in major depression: a double-blind and placebo-controlled trial.Jahn H, Schick M, Kiefer F, Kellner M, Yassouridis A, Wiedemann K Department of Psychiatry and Psychotherapy, University Hospital Hamburg-Eppendorf, Hamburg, Germany. jahn@uke.uni-hamburg.de BACKGROUND: Inhibitors of steroid synthesis have been reported to exert antidepressive effects, according to preliminary findings. OBJECTIVE: To test whether the addition of metyrapone to standard antidepressants induces a more rapid, more efficacious, and sustained treatment response in patients with major depression. DESIGN: Double-blind, randomized, placebo-controlled trial. SETTING: Hospitalized care. PATIENTS: Sixty-three inpatients with a DSM-IV diagnosis of major depression and a baseline score 18 points or higher on the Hamilton Rating Scale for Depression. INTERVENTIONS: Random allocation to 2 treatment groups receiving either placebo or metyrapone (1 g/d) for the first 3 weeks during a 5-week treatment with standard serotonergic antidepressants (nefazodone or fluvoxamine). MAIN OUTCOME MEASURES: Primary outcome criteria were the number of responders and the time to onset of action. Responder rates were considered twice after 3 and 5 weeks with a definition of treatment response as 30% and 50% reduction, respectively, of baseline Hamilton Rating Scale for Depression scores. Onset of action was defined as the time point at which at least a 20% reduction of baseline Hamilton Rating Scale for Depression scores occurred. RESULTS: Using intention-to-treat analysis, we found that a higher proportion of patients receiving metyrapone showed a positive treatment response at day 21 (23 of 33 patients) and at day 35 (19 of 33 patients) compared with placebo patients (day 21: 13 of 30 patients; Fisher exact P = .031; day 35: 10 of 30 patients; Fisher exact P = .047). The clinical course of patients treated with metyrapone showed an earlier onset of action (Kaplan-Meier analysis; log-rank test P<.006) beginning in the first week. The plasma concentrations of corticotropin and deoxycortisol were significantly higher during metyrapone treatment (multivariate analysis of covariance, P<.05), whereas cortisol remained largely unchanged. Metyrapone treatment was well tolerated without serious adverse effects. CONCLUSIONS: Metyrapone is an effective adjunct in the treatment of major depression, accelerating the onset of antidepressant action. A better treatment outcome compared with standard treatment and a sustained antidepressive effect were observed. Published 7 December 2004 in Arch Gen Psychiatry, 61(12): 1235-44.
