About this study

Official title: Agomelatine Augmentation in Early-Nonresponsive Patients With Major Depressive Disorder Receiving SSRIs or SNRIs: a Multicenter, Randomized, Double-blind, Placebo-controlled Clinical Trial

The purpose of this study was to investigate the efficacy and safety of antidepressant augmentation with agomelatine in the treatment of patients with depression who did not demonstrate satisfying response to selective serotonin reuptake inhibitor (SSRI) and serotonin-noradrenaline reuptake inhibitor (SNRI) during their early phase of treatment; this study also aims to explore the effects of augmenting antidepressant treatment with agomelatine on various aspects, including sleep quality, quality of life, social functioning, and cognitive function in patients with MDD.

What is being measured

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

  1. Hamilton Depression Scale scores

    Depression severity; higher scores mean a worse outcome.

    Measured: Baseline (week 0), week 2, week 4, week 8

  2. Side Effect Rating Scale (SERS) scores

    Safety: frequency and severity of adverse events; higher scores mean a better outcome.

    Measured: Baseline (week 0), week 2, week 4, week 8

Secondary outcomes (9)
  1. Patient Health Questionnaire (PHQ-9) scores

    Self-report depression severity; higher scores mean a worse outcome.

    Measured: Baseline (week 0), week 2, week 4, week 8

  2. Hamilton Anxiety Rating Scale (HAMA) scores

    Anxiety severity; higher scores mean a worse outcome.

    Measured: Baseline (week 0), week 2, week 4, week 8

  3. General Anxiety Disorder-7 (GAD-7) scores

    Self-report anxiety severity; higher scores mean a worse outcome.

    Measured: Baseline (week 0), week 2, week 4, week 8

  4. Changes in Clinical Global Impression (CGI) scores

    Symptom severity; higher scores mean a worse outcome.

    Measured: Baseline (week 0), week 2, week 4, week 8

  5. Snaith-Hamilton Pleasure Scale (SHAPS) scores

    Self-reported severity of anhedonia; higher scores mean a worse outcome.

    Measured: Baseline (week 0), week 2, week 4, week 8

  6. Sheehan Disability Scale (SDS) scores

    Self-report tool that assesses functional impairment in work/school, social life, and family life; higher scores mean a worse outcome.

    Measured: Baseline (week 0), week 2, week 4, week 8

  7. Quality of life (EQ-5D-3L) scores

    Self-report Quality of life; higher scores mean a better outcome.

    Measured: Baseline (week 0), week 2, week 4, week 8

  8. performance of Neurocognitive test, including executive function, attention, processing speed, and memory

    Neurocognitive function; higher scores mean a better outcome.

    Measured: Baseline (week 0), week 2, week 4, week 8

  9. Athens Insomnia Scale (AIS) scores

    Self-report severity of insomnia; higher scores mean a worse outcome.

    Measured: Baseline (week 0), week 2, week 4, week 8

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Agomelatine in people with Major Depressive Disorder, run by Central South University at 1 site in China.

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 0 inclusion and 11 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 1 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. 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. Some participants in this study may receive a placebo. 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?

Hamilton Depression Scale scores (time frame: Baseline (week 0), week 2, week 4, week 8). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04589143, which also lists 1 linked publication.

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 1 Apr 2024.
