European neuropsychopharmacology : the journal of the European College of Neuropsychopharmacology June 1, 2026 Andreas Reif, Yağcıoğlu Ae Anıl, Istvan Bitter et al. 3 citations

Optimising patient outcomes in treatment resistant depression (TRD) requires treatments which provide sustained remission, without relapse, and tolerability in the long term. ESCAPE-LTE (NCT04829318) was a phase IV, single-arm, 2-year (104 weeks) long-term extension of ESCAPE-TRD (NCT04338321; 32 weeks), a rater-blinded, randomised, active-controlled trial, which evaluated the safety,...

Safety and tolerability of esketamine nasal spray versus quetiapine extended release in patients with treatment resistant depression.

European neuropsychopharmacology : the journal of the European College of Neuropsychopharmacology August 1, 2024 Roger S McIntyre, Istvan Bitter, Jozefien Buyze et al. 30 citations

In ESCAPE-TRD (NCT04338321), esketamine nasal spray (NS) significantly increased the probability of remission at Week 8, and of being relapse-free through Week 32 after remission at Week 8, versus quetiapine extended release (XR) in patients with treatment resistant depression (TRD). Here, we explore the time course, burden and consequences of treatment emergent adverse events (TEAEs) in the...

JAMA Psychiatry June 5, 2019 Ella Daly, Madhukar H. Trivedi, Adam Janik et al. 766 citations

Importance: Controlled studies have shown short-term efficacy of esketamine for treatment-resistant depression (TRD), but long-term effects remain to be established. Objective: To assess the efficacy of esketamine nasal spray plus an oral antidepressant compared with an oral antidepressant plus placebo nasal spray in delaying relapse of depressive symptoms in patients with TRD in stable...
