Eketamine, ketamine’s enantiomer, is designed for use in tretment resistant depression, both unipolar and bipolar. Many publications have demonstrated the effect of ketamine/esketamine (mainly administered intravenously) in treatment resistant depression, with effect seen after an hour after administration. The therapeutic effect after single administration can last up to one week. In addition, it was shown that ketamine can reduce the intensity of suicidal thoughts.

Primary
| Measure | Time frame |
|---|---|
| Main Objective: to determine the efficacy and dose response of Esketamine, administered by inhalation from Dry Powder Inhaler, compared with placebo, in subjects with treatment resistant depression in the course of major depressive disorder, as assess by change from baseline in the Montgomery-Åsberg Depression Rating Scale (MADRS) total score at Day 14 of treatment phase.;Secondary Objective: -To evaluate effect of inhaled Esketamine in TRD subjects, compared to placebo -To evaluate durability of Esketamine’s antidepressant response in TRD subjects defined by ‘time to relapse’ (relapse assessed for responders and remitters and defined when MADRS total score in 2 consecutive assessments after Day 14 exceeds 50% MADRS baseline total score value. Time to relapse is to be computed from Day 14 to the first of two assessments fulfilling assumptions above) -To investigate safety and tolerability of inhaled Esketamine in TRD subjects, -To evaluate the pharmacokinetic properties of inhaled Esketamine (and its main metabolite Esnorketamine) in TRD subjects, Exploratory objectives: -to investigate correlation of Val66Met BDNF polymorphism with Esketamine antidepressive efficacy in subjects with TRD -to investigate levels of inflammatory cytokines as Esketamine’s efficacy predictive biomarkers. -to measure Esketamine’s metabolites concentrations – hydroxynorketamines.;Primary end point(s): Change from baseline (day 1, predose) in MADRS total score at Day 14 (3 days post last dose);Timepoint(s) of evaluation of this end point: at the end of treatment phase on Day 14 | — |
Secondary
| Measure | Time frame |
|---|---|

A subject is to be consider as a remitter while having clinical remission on Day 14, • Time to relapse (relapse assessed for responders and remitters and defined when MADRS total score in 2 consecutive assessments after Day 14 exceeds 50% MADRS baseline total score value.
