Achtergrond van het onderzoek
Title:
Pharmacological Treatment of Psychotic Depression.
Objectives:
Primary:
1. To compare in inpatients with psychotic depression the antidepressive efficacy at seven weeks of three treatment arms: [1] 7 weeks venlafaxine (maximum dose 375 mg); [2] 7 weeks imipramine (dose adjustment to adequate plasma levels of 200 ? 300 ug/L); [3] 7 weeks venlafaxine (maximum dose 375 mg) plus quetiapine (max. 600 mg/day).
Secondary:
1. To compare in patients with psychotic depression the tolerability of venlafaxine, imipramine and venlafaxine plus quetiapine.
2. To find factors modifying treatment efficacy, such as response to earlier treatments during current episode.
3. To evaluate efficacy and tolerability of continuation treatment during 4 months in responders to treatment at 7 weeks.
Type of patients:
In-patients with psychotic depression.
Number of patients:
To include 180 patients (3 groups of 60 patients) 250 patients must be selected in 6 centres.
Trial design:
A double blind, randomised and stratified to the centres, multicentre study with a wash-out period, comparing 3 treatment strategies.
Trial treatments:
1. Venlafaxine (maximum dose 375 mg);
2. Imipramine (dose adjustment to adequate plasma levels of 200 ? 300 ug/L);
3. Venlafaxine (maximum dose 375 mg) plus quetiapine (max. 600 mg/day).
Duration of treatment:
One week wash-out and 7 weeks acute treatment with venlafaxine or imipramine or venlafaxine plus quetiapine. Total: 8 weeks.
Follow-up:
Continuation treatment of responders during 4 months.
Primary endpoints:
1. Proportion of responders.
Secondary endpoints:
1a. Change in HRSD scores;
1b. Change in CGI scores;
2. Time to response;
3. Adverse effects;
4. Group differences especially with regard to response to earlier treatments during current episode.
