A randomised controlled trial of oral S-ketamine as add-on medication for patients with treatment-resistant major depressive disorder

This double-blind, placebo-controlled trial (n=128) investigates the antidepressant efficacy of oral esketamine as an add-on medication for patients with treatment-resistant major depressive disorder (TRD).

Conducted by the University Medical Centre Groningen in the Netherlands, the trial aims to assess changes in symptom severity using the HDRS17 scale and explore various secondary endpoints, including effects on sleep, memory, anxiety, and brain activity.

The study involves adults aged 18-80 with TRD and employs a randomised controlled design with a placebo group. The treatment duration is six weeks, with follow-up evaluations at weeks 7, 8, and 10. The trial, sponsored by ZonMw, incorporates multiple sites and has been ongoing since August 30, 2016.
