Total Discontinuation - Emergent Signs and Symptoms (DESS) Score Over the First 2 Weeks of the Double-blind Phase
Tidsramme: Double-blind phase: Week 1 (Study Day 175), Week 2 (Study Day 182)
|
Clinician-administered 43-item assessment to evaluate discontinuation-emergent symptoms resulting from withdrawal from study treatment.
Total score=sum of number of new symptoms and old (but worse) symptoms (score=1) and old and unchanged symptom, absent, or old symptom but improved (score=0); total possible range 0 to 43.
Higher score=more symptoms.
New symptom=any symptom that appeared within 7 days before DESS administration; old symptom=any symptom that appeared 7 days before DESS administration and continued into 7-day period.
DESS calculated as 2*mean(of DESSDB Week 1, DESSDB Week 2).

Percentage of Participants With Taper Adverse Events (AEs) in the Double-blind Phase
Tidsramme: Double-blind phase: Baseline (Study Day 168) up to Week 4 (Study Day 196)
|
Any untoward medical occurrence in a patient who received study drug was considered an AE without regard to possibility of causal relationship.
Taper-emergent AEs (TPAEs) are those events which occurred during the double-blind period but did not occur during the last 7 days of the on-therapy period or existed during the last 7 days and worsened in the double-blind period.

Percentage of Participants Who Were Unable to Successfully Complete Tapering of the Study Drug Because of the Number and/or Severity of Their Discontinuation Symptoms
Tidsramme: Double-blind phase: Baseline (Study Day 168) up to Week 4 (Study Day 196)
|
Discontinuation symptoms may occur following abrupt cessation of serotonergic antidepressants in a minority of participants following short-term treatment of an episode of Major Depressive Disorder (MDD).
The symptoms include emotional and somatic symptoms such as dizziness, nausea, and paresthesia and typically appear within 2 to 3 days of reducing the dose or stopping the antidepressant medication.
Discontinuation symptoms are usually mild and resolve spontaneously within a week in the majority of patients, though a minority can have intense and prolonged symptoms.
