What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline to Day 28 in Hamilton Depression Rating Scale (HAM-D) Total Score

    The HAM-D contains 17 items pertaining to symptoms of depression experienced over the past week. The questions cover core symptoms of depression as well as appetite and sleep (3 items). Items are scored on a likert scale of 0-4 or 0-2 depending on the item with a possible range of 0-52, with higher scores indicating greater severity of depressive symptoms.

    Measured: Baseline up to Day 28

Secondary outcomes (9)
  1. Change From Baseline Over Time for HAM-D Total Score

    The HAM-D contains 17 items pertaining to symptoms of depression experienced over the past week. The questions cover core symptoms of depression as well as appetite and sleep (3 items). Items are scored on a likert scale of 0-4 or 0-2 depending on the item with a possible range of 0-52, with higher scores indicating greater severity of depressive symptoms.

    Measured: Baseline up to Week 4

  2. Change From Baseline Over Time for Patient Health Questionnaire 9-item (PHQ-9) Total Score

    The PHQ-9 is a validated 9-item, patient-reported outcomes (PRO) measure to assess depressive symptoms. The scale scores each of the 9 symptom domains of the diagnostic and statistical manual of mental disorders, fifth edition (DSM-5) major depressive disorder (MDD) criteria and it has been used both as a screening tool and a measure of response to treatment for depression. Each item is rated on a 4-point scale (0=not at all, 1=several days, 2=more than half the days, and 3=nearly every day). The participant's item responses are summed to provide a total score (range of 0 to 27), with higher scores indicating greater severity of depressive symptoms.

    Measured: Baseline up to Week 4

  3. Percentage of Participants With Response Based on HAM-D Total Score Over Time

    Percentage of participants with response based on HAM-D total score over time will be reported. The HAM-D contains 17 items pertaining to symptoms of depression experienced over the past week. The questions cover core symptoms of depression as well as appetite and sleep (3 items). Items are scored on a likert scale of 0-4 or 0-2 depending on the item with a possible range of 0-52, with higher scores indicating greater severity of depressive symptoms.

    Measured: Up to Week 4

  4. Percentage of Participants With Response Based on PHQ-9 Total Score Over Time

Each item is rated on a 4-point scale (0=not at all, 1=several days, 2=more than half the days, and 3=nearly every day). The participant's item responses are summed to provide a total score (range of 0 to 27), with higher scores indicating greater severity of depressive symptoms.

    Measured: Up to Week 4

  5. Percentage of Participants With Remission Based on HAM-D Total Score Over Time

    Percentage of participants with remission based on HAM-D total score over time will be reported. The HAM-D contains 17 items pertaining to symptoms of depression experienced over the past week. The questions cover core symptoms of depression as well as appetite and sleep (3 items). Items are scored on a likert scale of 0-4 or 0-2 depending on the item with a possible range of 0-52, with higher scores indicating greater severity of depressive symptoms.

    Measured: Up to Week 4

  6. Percentage of Participants With Remission Based on PHQ-9 Total Score Over Time

    Percentage of participants with remission based on PHQ-9 total score over time will be reported. The PHQ-9 is a validated 9-item, PRO measure to assess depressive symptoms. The scale scores each of the 9 symptom domains of the DSM-5 MDD criteria and it has been used both as a screening tool and a measure of response to treatment for depression. Each item is rated on a 4-point scale (0=not at all, 1=several days, 2=more than half the days, and 3=nearly every day). The participant's item responses are summed to provide a total score (range of 0 to 27), with higher scores indicating greater severity of depressive symptoms.

The HAM-D contains 17 items pertaining to symptoms of depression experienced over the past week. The questions cover core symptoms of depression as well as appetite and sleep (3 items). Items are scored on a likert scale of 0-4 or 0-2 depending on the item with a possible range of 0-52, with higher scores indicating greater severity of depressive symptoms.

    Measured: Up to Week 4

  8. Percentage of Participants With Clinically Meaningful Improvement Based on PHQ-9 Total Score Over Time

    Percentage of participants with clinically meaningful improvement based on total score PHQ-9 total score over time will be reported. The PHQ-9 is a validated 9-item, PRO measure to assess depressive symptoms. The scale scores each of the 9 symptom domains of the DSM-5 MDD criteria and it has been used both as a screening tool and a measure of response to treatment for depression.

  9. Change From Baseline Over Time for Clinical Global Impression-Severity (CGI-S) Score

    The CGI-S is a clinician-rated scales that measure illness severity. The CGI has proved to be a robust measure of efficacy in many clinical drug trials and is easy and quick to administer. The CGI-S is rated on a 7-point scale, with the severity of illness scale using a range of responses from 1 (normal) through to 7 (among the most severely ill participants).

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Esketamine 56 mg and Esketamine 84 mg in people with Depressive Disorder, Treatment-Resistant, run by Janssen Korea, Ltd., Korea at 6 sites in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change From Baseline to Day 28 in Hamilton Depression Rating Scale (HAM-D) Total Score (time frame: Baseline up to Day 28). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Aug 2026.
