E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To examine in depressed patients who reach a 6-month stable depression remission during optimal AD treatment: 1) whether discontinuation is possible; 2) when discontinuation is possible; and 3) in whom discontinuation is possible. |
Bij depressieve patiënten die gedurende optimale behandeling met antidepressiva een 6 maanden stabiele depressie remissie hebben bereikt, onderzoeken 1) of afbouw van antidepressiva mogelijk is, 2) wanneer afbouw mogelijk is, en 3) bij wie afbouw mogelijk is. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Having a stable depression remission as evidenced by reporting an IDS score ≤21 (i.e. no moderate or severe depressive symptoms) during two consecutive bimonthly assessments and a confirmed absence of a DSM-5 diagnosis of MDD during 6 months, as observed in the OPERA-MONITOR study.
• Use of sertraline (50, 100, 150 or 200 mg/day) or citalopram (10, 20, 30 or 40 mg/day).
• Willing to be randomized and provide written informed consent. |
• Aanwezigheid van een stabiele remissie van depressie, gedefinieerd als twee opeenvolgende IDS scores ≤21 (d.w.z. geen matige of ernstige depressieve symptomen) gedurende 2-maandelijkse metingen én afwezigheid van een depressieve stoornis (MDD) volgens DSM-5 criteria gedurende 6 maanden, zoals geobserveerde in de OPERA-Monitor studie.
• Gebruik van sertraline (50, 100, 150 of 200 mg/per dag) of citalopram (10, 20, 30 of 40 mg/per dag).
• Bereid om gerandomiseerd te worden en schriftelijk geïnformeerde toestemming te geven. Patiënten die niet gerandomiseerd willen worden, worden uitgenodigd voor deelname in een externe referentiegroep (N=200 van de 600). |
|
E.4 | Principal exclusion criteria |
• Earlier inpatient admission for depression.
• History of >3 prior episodes for which treatment was started.
• Overall treatment period with antidepressant for the last depressive episode did last more than 18 months (chronic patients are excluded: in this difficult-to-treat group continuation of antidepressants is recommended as a-priori relapse risk is known to be high).
• Presence of other clinically overt primary psychiatric conditions that warrant different medical attention (earlier confirmed psychosis, schizophrenia or bipolar depression for which medical care has been provided, or alcohol or drug addiction which is currently treated).
• Insufficient mastery of Dutch language. |
• Eerdere intramurale opname voor depressie.
• >3 eerdere depressieve episodes waarvoor behandeling is gestart.
• Totale behandelperiode met antidepressiva voor de laatste depressieve episode duurde langer dan 18 maanden (chronische patiënten worden geexcludeerd: in deze moeilijk te behandelen groep is continuering van antidepressiva aanbevolen omdat het a-priori risico op terugval hoog is).
• Aanwezigheid van andere primaire psychiatrische aandoening die een andere medisch beleid vereist (eerder vastgestelde psychose of schizofrenie of bipolaire depressie waarvoor medische zorg is ontvangen, alcohol- of drugsverslaving waarvoor momenteel behandeld wordt)
• Onvoldoende beheersing van de Nederlandse taal. |

E.5 End points |
E.5.1 | Primary end point(s) |
Primary outcome involves sustained remission time measured as time of follow-up without severe depressive symptoms, inpatient admission for depression and suicide (attempt). Severe depressive symptoms are defined as having an IDS score>25 (moderately/severely depressed) and meeting DSM-5 criteria for MDD for 2 weeks according the psychiatric MINI interview. Suicide attempt is assessed using suicide IDS and MINI items followed up with the suicide behaviour question of the Columbia Suicide Severity Rating Scale (C-SSRS) Screen Version) and should be confirmed by two OPERA-researchers. |
Duur van consistente remissie (tijd zonder depressieve episode, intramurale opname voor depressie en suïcide(poging)).
Ernstige depressieve symptomen zijn gedefinieerd als een IDS score>25 en voldoen aan de DSM-5 criteria voor een depressieve stoornis (MDD) gedurende 2 weken volgens het psychiatrische MINI interview. Suïcidepoging wordt vastgesteld met behulp van het suïcide items uit de IDS en MINI, gevolgd door de vraag over suïcide gedrag uit de Columbia Suicide Severity Rating Scale (C-SSRS) Screen Versie en bevestiging van twee OPERA-onderzoekers. |
