Brief summary: The purpose of the study is to determine the efficacy, safety and pharmacokinetics of inhaled Esketamine in participants with treatment-resistant depression (TRD) in the course of Major Depressive Disorder (MDD). The study is to determine the efficacy and dose response of three Esketamine doses, compared with placebo.

Detailed description: This is a randomized, multiple dose, placebo-controlled, double-blind, multicentre study of Esketamine DPI, inhalation powder delivered via dry powder inhaler (DPI) in participants with TRD in the course of MDD. There are 3 study phases: Screening phase, a two weeks double-blind treatment phase and a 6-week follow-up phase. Participants are to be randomized in 1:1:1:1 ratio to receive placebo or one of the three doses of Esketamine DPI. Participants from each group will receive different dosing sequences, consider as a single dose, corresponding to low, medium, high Esketamine dose or placebo. Participants will undergo one cycle of treatment consisting of four doses of Esketamine DPI or placebo over 14-day period. Participants safety will be monitored throughout the study.

Eligibility criteria: Inclusion Criteria:

1. Gender: female or male,
2. Age: 18 - 65 years old, inclusive, on the day of Screening,

3. Participant has a history or current signs and symptoms of chronic obstructive pulmonary disease (COPD), asthma, liver or renal insufficiency, significant cardiac, vascular, pulmonary, gastrointestinal, endocrine, hematologic, neurologic, rheumatologic or metabolic disturbances that are uncontrolled with medication change during last three months before Screening and/or that could influence the present general health condition at the Investigator's discretion,
4. Participant has uncontrolled hypertension,
5. Upper respiratory tract and/or chest infection and/or inflammation within 2 weeks preceding the first administration and during the treatment phase,
6. Participant took part in other clinical trial within 90 days preceding the Screening,
7. Known allergy or hypersensitivity, intolerance or contraindication to Esketamine/ketamine or its derivatives and/or to any study product excipients,
8. Blood drawn within 30 days prior to inclusion to the study,
9. History of drug, alcohol, chemical, sedatives or sleeping medications abuse or dependence (except nicotine or caffeine) within 2 years prior to Screening,
10. Lifetime abuse or dependence on ketamine or phencyclidine,
11. Positive results from pregnancy test for female participants,
12. Lactation in female participants,
13. Positive drug screen (except benzodiazepines evaluation during follow-up) or alcohol breath test.
