A Study to Assess the Pharmacokinetics, Safety, and Tolerability of Intranasally Administered Esketamine in Healthy Participants
- Registration Number
- NCT01780259
- Lead Sponsor
- Janssen Research & Development, LLC
- Brief Summary
The primary purpose of the study is to evaluate the pharmacokinetics (what the body does to the medication) of intranasally (through the nose) administered esketamine in healthy participants.
- Detailed Description
This is a single-center study with 3 cohorts (groups). Approximately 58 participants will be enrolled in this study. In Cohort 1, approximately 16 participants will be enrolled for up to 78 days and they will receive 4 different single-dose regimens (Treatment A, B, C and D) of intranasal spray of esketamine solution in a crossover manner (participants will be switched from one single-dose regimen to another) and in an open label manner (both the investigator and the participant know the intervention received by the participant). In Cohort 2, approximately 14 participants will be enrolled for up to 35 days and they will receive 1 regimen of intranasal esketamine (Treatment D) in an open label manner. In Cohort 3, approximately 28 participants will be enrolled and they will be randomly assigned to receive either Treatment E (intranasal esketamine spray) or Treatment F (intranasal placebo spray) in a double blind manner (both the investigator and the participant do not know the intervention received by the participant). Safety evaluations will include assessment of adverse events, targeted nasal examinations, laboratory tests, electrocardiogram, physical examination, pulse oximetery, and vital signs.

Group Intervention Description Cohort 3: Treatment E Placebo Participants will receive 1 spray of esketamine solution in each nostril, 4 times with 10 minutes interval between each repeated sprays (total dose: 112 mg). Single dose of oral placebo will be administered 5 minutes before the first intranasal spray of esketamine solution. Cohort 3: Treatment F Placebo Participants will receive 1 spray of placebo solution in each nostril, 4 times with 10 minutes interval between each repeated sprays (total dose: 112 mg). Single 0.25-mg oral dose of triazolam will be administered 5 minutes before the first intranasal spray of placebo solution. Cohort 3: Treatment F Triazolam Participants will receive 1 spray of placebo solution in each nostril, 4 times with 10 minutes interval between each repeated sprays (total dose: 112 mg). Single 0.25-mg oral dose of triazolam will be administered 5 minutes before the first intranasal spray of placebo solution. Cohort 1: Treatment A Esketamine Participants will receive 1 spray of esketamine solution in each nostril once (total dose: 28 mg). Cohort 1: Treatment B Esketamine Participants will receive 1 spray of esketamine solution in each nostril twice, with 5 minutes interval (total dose: 56 mg). Cohort 3: Treatment E Esketamine Participants will receive 1 spray of esketamine solution in each nostril, 4 times with 10 minutes interval between each repeated sprays (total dose: 112 mg). Single dose of oral placebo will be administered 5 minutes before the first intranasal spray of esketamine solution. Cohort 1: Treatment C Esketamine Participants will receive 1 spray of esketamine solution in each nostril thrice, with 5 minutes interval between each repeated sprays (total dose 84 mg). Cohort 2: Treatment D Esketamine Participants will receive 1 spray of esketamine solution in each nostril thrice, with 10 minutes interval between each repeated sprays (total dose 84 mg). Cohort 1: Treatment D Esketamine Participants will receive 1 spray of esketamine solution in each nostril thrice, with 10 minutes interval between each repeated sprays (total dose 84 mg).
