Intervention / Treatment
Detailed Description
This is to be one-centre, single ascending dose and double-blind placebo controlled multiple dose three part study of Esketamine DPI (dry powder inhaler) in healthy volunteers.
PART A is a single dose, open-label part with Esketamine DPI inhalations administered with dose escalation between cohorts.
PART B is a single dose, open-label part with Esketamine DPI inhalations administered in different dosing sequences with dose escalation between cohorts.
PART C is a multiple dose, double-blind, placebo-controlled part with Esketamine DPI inhalations administered in different cycles of treatment (with four dosing sequences within two weeks) with dose escalation between cohorts. Participants in this part will be randomized to receive Esketamine DPI or placebo in 3:1 ratio.
Pharmacokinetic properties and safety of Esketamine DPI will be determined following different number of inhalations in PART A, different dosing sequences in PART B and different cycles of treatment in PART C.

Placebo Comparator: PART C placebo
4 cohorts will receive multiple dose of matching placebo in two weeks' time.
|
Participants will receive different cycle of treatment consisting of 4 dosing sequences administered within 2 weeks. Participants in this part will be randomized to receive Esketamine DPI or placebo in 3:1 ratio. In each cohort, number of placebo inhalations within a dosing sequence will correspond to number of Esketamine DPI inhalations. |
