Outcome Measures

Primary Outcomes (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

    From baseline to Week 8

Secondary Outcomes (13)

  • Change from baseline in Hamilton Depression Scale (HAMD-17) at the end of treatment (week 8)

    From baseline to Week 8

  • 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)

    From baseline to Week 8

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

    Week 8

  • The efficiency and remission of the MADRS score

    Baseline and week 8

  • The efficiency and remission of the HAMD-17 score

Subject has recurrent Major Depressive Disorder (MDD) as the primary diagnosis according to Diagnostic and Statistical Manual of Mental Disorders (DSM-5, 5th Edition), single episode or recurrent episodes (classification code 296.2/296.3).The duration of the current depressive episode should be ≥3 months for first-episode patients and ≥1 month for relapsing patients;
  • \. Subjects with a Montgomery-Asberg Depression Rating Scale (MADRS) score ≥ 26 at screening and baseline. Subjects with Clinical Global Impression Scale Disease Severity CGI-S severity score ≥ 4 at screening and baseline. Score of first item (depressed mood) of the HAMD-17 scale ≥2 at the screening and baseline.
  • Be able to read and understand the study procedures and trial requirements, agree to abide by the restrictions of the trial and return to the site on time for evaluation, and sign the informed consent form prior to the trial.

You may not qualify if:

  • \. Subjects with ≥ 25% reduction in MADRS score in the baseline period compared to the screening period;
  • \. There is a clinically significant risk of suicide or risk of self-injury and harm to others. Those who meet any of the following:
  • A score of ≥4 on item 10 (Suicidal Ideation) of the MADRS scale;
  • Subjects who in the judgment of the investigator, are at significant risk for suicide (e.g., participant answered "yes" to question 4 (active suicidal ideation with intent to act but no specific plan) or question 5 (active suicidal ideation with a specific plan and intent) on the Screening C-SSRS and the most recent suicidal intent or suicidal plan occurred within the last six months);
  • Attempted suicide during the current depressive episode;
  • \. Subjects meet DSM-5 diagnostic criteria for other mental disorders (Schizophrenia spectrum and other psychotic disorders, bipolar and related disorders, anxiety disorders, obsessive-compulsive and related disorders, somatic symptoms and related disorders, substance-related and addiction disorders, etc.)
  • \. Subjects who meet any of the following diagnoses of depressive disorders:
  • Those who have been determined by the investigator to have TRD (current or prior use of 2 or more antidepressants with different mechanisms that have not been effective with a full course (at least 8 weeks) of treatment at the full dosage (the maximum recommended amount of the instructions);
  • Subjects with depressive disorders due to other types of mental disorders or somatic diseases (e.g., depressive disorders due to hypothyroidism);
  • Subjects with depressive disorders due to substances/drugs;
  • \. Subjects who stopped using the following drugs for less than 5 half-lives prior to randomization:
  • CYP2C19 and CYP3A4 strong inducers and strong inhibitors (e.g., fluoxetine, rifampicin, carbamazepine, etc.);
  • Combined use of drugs that cause QTc interval prolongation (e.g., levofloxacin, fluconazole, ondansetron, amiodarone, metronidazole, erythromycin, and haloperidol, etc.) or drugs that can cause QTc interval prolongation and may induce torsade de pointes ventricular tachycardia;
  • Antipsychotics, antidepressants, or mood stabilizers;
  • \. Subjects who have failed previous treatment with a full course (at least 8 weeks) of sertraline at the maximum recommended dose or who have a known allergy to sertraline;
  • +22 more criteria
