What is being measured

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

  1. Change from baseline in Montgomery Asperger Depression Scale (MADRS) score at the end of treatment (week 8)

    The MADRS is a clinician-rated scale to assess depressive symptomatology during the preceding week. Participants are rated on 10 items (feelings of sadness, lassitude, pessimism, inner tension, suicidality, reduced sleep or appetite, difficulty concentrating, and lack of interest) each on a 7-point scale from 0 (no symptoms) to 6 (symptoms of maximum severity). The total score ranges from 0 to 60 with a higher score indicating more depression. A negative change score indicates improvement

    Measured: From baseline to Week 8

Secondary outcomes (13)
  1. Change from baseline in Hamilton Depression Scale (HAMD-17) at the end of treatment (week 8)

    The HAMD-17 is a clinician-based assessment of depressive symptoms. The total score ranges from 0 to 53 with a higher score indicating more depression. A score of 0-9 is generally accepted to be within the normal range (or in clinical remission), while a score of greater than 17 indicates moderate to severe depression symptoms.

    Measured: From baseline to Week 8

  2. Change from baseline in The Clinical Global Impression Scale (CGI-S) scores at the end of treatment (week 8) at the end of treatment (week 8)

    The CGI-S evaluates the severity of psychopathology on a scale of 0 to 7. Considering total clinical experience, a participant is assessed on severity of mental illness at the time of rating according to: 0=not assessed; 1=normal (not at all ill); 2=borderline mentally ill; 3=mildly ill; 4=moderately ill; 5=markedly ill; 6=severely ill; 7=among the most extremely ill participants. The CGI-S permits a global evaluation of the participant's condition at a given time.

    Measured: From baseline to Week 8

  3. Clinical Global Impression Scale of Improvement (CGI-I) score at the end of treatment (week 8)

    The CGI-I scale is a clinician-rated instrument that measures the improvement of the participant's symptoms of depression. It is a 7-point scale where a score of 1 indicates that the participant is "very much improved," a score of 4 indicates that the participant has experienced "no change," and a score of 7 indicates that the participant is "very much worse."

    Measured: Week 8

  4. The efficiency and remission of the MADRS score

    Effectiveness is defined as ≥ 50% reduction in MADRS score relative to baseline after treatment. Remission is defined as MADRS score ≤ 10 after treatment.

    Measured: Baseline and week 8

  5. The efficiency and remission of the HAMD-17 score

    Effectiveness is defined as ≥50% reduction in HAMD-17 score relative to baseline after treatment. Remission is defined as HAMD-17 score ≤7 after treatment.

    Measured: Baseline and week 8

  6. CGI-I score

    The CGI-I scale is a clinician-rated instrument that measures the improvement of the participant's symptoms of depression. It is a 7-point scale where a score of 1 indicates that the participant is "very much improved," a score of 4 indicates that the participant has experienced "no change," and a score of 7 indicates that the participant is "very much worse."

    Measured: Week 1, week 2, week 4 and week 6

  7. Change from baseline in HAMD-17 score

    The HAMD-17 is a clinician-based assessment of depressive symptoms. The total score ranges from 0 to 53 with a higher score indicating more depression. A score of 0-9 is generally accepted to be within the normal range (or in clinical remission), while a score of greater than 17 indicates moderate to severe depression symptoms.

    Measured: Week 1, week 2, week 4 and week 6

  8. Change from baseline in MADRS score

    The MADRS is a clinician-rated scale to assess depressive symptomatology during the preceding week. Participants are rated on 10 items (feelings of sadness, lassitude, pessimism, inner tension, suicidality, reduced sleep or appetite, difficulty concentrating, and lack of interest) each on a 7-point scale from 0 (no symptoms) to 6 (symptoms of maximum severity). The total score ranges from 0 to 60 with a higher score indicating more depression. A negative change score indicates improvement.

    Measured: Week 1, week 2, week 4 and week 6

  9. Change from baseline in HAMA score

    The HAMA is a clinician-rated instrument administered to assess severity of anxiety, its improvement during the course of treatment, and the timing of such improvement. This instrument will be completed by qualified and trained Investigator site raters based on a semi-structured interview for his/her assessment of the participant. The scale consists of 14 items. Each item is rated on a scale of 0 (feeling not present) to 4 (very severe prevalence of the feeling). The HAMA total score is the sum of the 14 items and the score ranges from 0 to 56.

    Measured: Week 1, week 2, week 4 and week 6

  10. Change from baseline in CGI-S score

    The CGI-S evaluates the severity of psychopathology on a scale of 0 to 7. Considering total clinical experience, a participant is assessed on severity of mental illness at the time of rating according to: 0=not assessed; 1=normal (not at all ill); 2=borderline mentally ill; 3=mildly ill; 4=moderately ill; 5=markedly ill; 6=severely ill; 7=among the most extremely ill participants. The CGI-S permits a global evaluation of the participant's condition at a given time.

    Measured: Week 1, week 2, week 4 and week 6

  11. The efficiency and remission of the HAMD-17 score

    Effectiveness is defined as ≥50% reduction in HAMD-17 score relative to baseline after treatment. Remission is defined as HAMD-17 score ≤7 after treatment.

    Measured: Week 1, week 2, week 4 and week 6

  12. The efficiency and remission of the MADRS score

    Effectiveness is defined as ≥ 50% reduction in MADRS score relative to baseline after treatment. Remission is defined as MADRS score ≤ 10 after treatment.

    Measured: Week 1, week 2, week 4 and week 6

  13. The percentage of subjects with a MARDS score reduction ≥ 25%

    Measured: Week 1and week 2

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Ammoxetine and Sertraline in people with Major Depressive Disorder (MDD), run by CSPC ZhongQi Pharmaceutical Technology Co., Ltd. at 2 sites 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 4 inclusion and 38 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 30 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 in Montgomery Asperger Depression Scale (MADRS) score at the end of treatment (week 8) (time frame: From baseline to Week 8). 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 30 Oct 2026.
