Cognitive Behavioural Analysis System of Psychotherapy (CBASp) Versus Escitalopram in Chronic Depression

Phase 3

• Conditions: Chronic Depression
• Interventions: Other: CBASP psychotherapy; Drug: Escitalopram

• Registration Number: NCT00837564
• Lead Sponsor: University Hospital Freiburg

Brief Summary

60 patients with chronic major depressive disorder according to DSM-IV will be included into the study. Patients will be randomized to receive an open treatment either with CBASP, a psychotherapy for chronic depression, or pharmacological treatment with Escitalopram for 28 weeks.

Detailed Description

The psychotherapeutic treatment with CBASP will be conducted in 2 weekly sessions for the first 4 weeks, one per week thereafter until week 9, followed by one session every 2 weeks for 20 more weeks. The starting dose for Escitalopram will be 10 mg/d for one week and will be increased to 20 mg/d after one week. The dosage can be reduced to 10 mg/d after day 7 to improve tolerance. Th MADRS-scale is the primary outcome measure; ratings will be performed by a blinded rater. If there is no improvement (reduction of less than 20% of the MADRS), patients will be crossed over in terms of adding the other treatment at week 8. Study patients will be asked to participate in fMRI, genetic and pharmacological substudies.
