About this study

This is a single-center, 4-period, fixed-sequence, open-label study. The study consists of Screening Period (Days -21 to -2), Open-label Treatment Period 1, 2, 3, 4 and End of Study (9 to 13 days after final dose or at Early Withdrawal). The total duration of study will be up to 98 days. For all 4 periods, the participants will be admitted into the study center on Day -1 of each treatment period and receive a 28 milligram (mg) (intravenous) or 84 mg (oral and intranasal) esketamine dose regimen on Day 1 of each period in a fixed sequence. Participants will also receive 500 mg of clarithromycin in period 4. Blood samples will be collected to evaluate the pharmacokinetic parameters. Participants' safety will be monitored throughout the study.

    Time frame: Pre-dose, 0.25, 0.33, 0.5, 0.66, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 12 hour (hr) post-dose on Day 1 in all periods

    The (AUC12h) is the area under the plasma concentration-time curve from time 0 to 12 hours Post-dose.

  4. Area Under the Plasma Concentration-Time Curve From Time Zero to Time of the Last Quantifiable Concentration AUC(0-last) of Esketamine

    Time frame: Pre-dose, 0.25, 0.33, 0.5, 0.66, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 18 hour (hr) post-dose on Day 1; 24, 36 hr post-dose on Day 2; 48 hr post-dose on Day 3 in all periods

    The (AUC [0-last]) is the area under the plasma concentration-time curve from time 0 to time of the last quantifiable concentration.

  5. Area Under the Plasma Concentration-Time Curve From Time Zero to Infinite Time (AUC [0-infinity]) of Esketamine

    Time frame: Pre-dose, 0.25, 0.33, 0.5, 0.66, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 18 hour (hr) post-dose on Day 1; 24, 36 hr post-dose on Day 2; 48 hr post-dose on Day 3 in all periods

    The AUC (0-infinity) is the area under the plasma concentration-time curve from time zero to infinite time, calculated as the sum of AUC(0-last) and C(0-last)/lambda(z), wherein AUC(0-last) is the area under the plasma concentration-time curve from time 0 to time of the last quantifiable concentrations; C(0-last) is the last observed quantifiable concentration; and lambda(z) is elimination rate constant.

  6. Percentage of Area Under the Plasma Concentration-time Curve Obtained by Extrapolation (%AUC [infinity,ex]) of Esketamine

    Percentage of area under the plasma concentration-time curve obtained by extrapolation (%AUC[inf,ex]) is calculated by dividing the difference of AUC(0-infinity) and AUC(0-last) by AUC(0-infinity) and then multiplying by 100 (AUC[0-infinity] - AUC[0-last])*100/AUC[0-infinity].

  11. Number of Participants With Adverse Events (AEs) or Serious Adverse Events (SAEs)

    Time frame: Throughout the duration of study (approximately up to 98 days)

    An AE is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship.
