Brief summary
The study aims to evaluate the efficacy and safety of Toludesvenlafaxine Hydrochloride Sustained-release Tablets compared to placebo in adults participants with generalized anxiety disorder over a period of 8 weeks.
Detailed description
The study consists of two periods: screening period (2 weeks) and double-blind treatment period (8 weeks). After the screening period, generalized anxiety disorder patients who satisfies the inclusion criteria are randomly assigned in the 1:1:1 ratio to receive either placebo or Toludesvenlafaxine Hydrochloride Sustained-release Tablets at two dose levels (80 ,160 mg/day) for 8 weeks. Participants are evaluated at screening, baseline visits and double-blind period.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline in the Hamilton Anxiety(HAMA) Rating Scale total score at endpoint | from baseline to week 8 | The HAMA Scale consist of 14 items that include psychic, somatic, and behavioral symptoms associated with anxiety. Each items is rated on a 5-point scale of 0(not present) to 4(very severe) so that scores may range from 0 to 56, with high scores indicating greater illness severity. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline in the Hamilton Anxiety(HAMA) Rating Scale psychic factor score (Items 1~6 and Item 14) at endpoint | from baseline to week 8 | The psychic factor score is the sum of items 1-6 and items 14(including items such as anxious mood, tension, fear, insomnia, and behavioral symptoms).Each items is rated on a 5-point scale of 0(not present) to 4(very severe) so that scores may range from 0 to 28, with high scores indicating greater illness severity. |
| Change from baseline in the Hamilton Anxiety(HAMA) Rating Scale somatic factor score (Items 7~13) at endpoint | from baseline to week 8 | The somatic factor score is the sum of items 7-13(including items such as cardiovascular, respiratory, and gastrointestinal symptoms).Each items is rated on a 5-point scale of 0(not present) to 4(very severe) so that scores may range from 0 to 28, with high scores indicating greater illness severity. |
| Change from baseline in the Hamilton Anxiety(HAMA) Rating Scale item 1（Anxious mood）Score at endpoint | from baseline to week 8 | The item is rated on a 5-point scale of 0(not present) to 4(very severe) so that score may range from 0 to 4, with high scores indicating greater illness severity. |
| Change from baseline in the Hamilton Anxiety(HAMA) Rating Scale item 2（Tension）Score at endpoint | from baseline to week 8 | The item is rated on a 5-point scale of 0(not present) to 4(very severe) so that score may range from 0 to 4, with high scores indicating greater illness severity. |
| Percentage of participants with response at endpoint | from baseline to week 8 | Response was defined as a≥50% reduction from baseline to endpoint in the HAMA total score. |
| Percentage of participants with remission at endpoint | from baseline to week 8 | Remission was defined as a HAMA total score ≤7 points at endpoint |
| Clinical Global Impression Scale - improvement (CGI-I) score at endpoint | from baseline to week 8 | The CGI-I scale measures the participant's improvement (or worsening) as assessed by the investigator relative to Baseline on a 7-point scale: 1, very much improved; 2, much improved; 3, minimally improved; 4, no change; 5, minimally worse; 6, much worse; or 7, very much worse. |
| Change from baseline in Clinical Global Impression Scale - severity (CGI-S) score at endpoint | from baseline to week 8 | The CGI-S scale is a 7-point scale to rate the severity of the patient's illness. Patient is assessed on severity of mental illness on the following scale: 1, normal, not at all ill; 2, borderline mentally ill; 3, mildly ill; 4, moderately ill; 5, markedly ill; 6, severely ill; or 7, extremely ill. |
| Change from baseline in the Sheehan Disability Scale(SDS) score at endpoint | from baseline to week 8 | The SDS scale consists of 3 items evaluating impairment in work/school， social life/leisure activities, and family life/home responsibilities. Each item is scored on a scale of 0(unimpaired) to 10(highly impaired). |
| Change from baseline in the Pittsburgh Sleep Quality Index (PSQI) score at endpoint | from baseline to week 8 | The scale consists of 3 items evaluating impairment in work/school， social life/leisure activities, and family life/home responsibilities. Each item is scored on a scale of 0(unimpaired) to 10(highly impaired). |
| Incidence and severity of adverse effects (AEs) | from baseline to week 8 | — |
| Change from baseline in the Columbia Suicide severity Rating Scale (C-SSRS) score at endpoint | from baseline to week 8 | The C-SSRS captured the occurrence, severity, and frequency of suicide-related thoughts and behaviors. Suicidal ideation: a "yes" answer to any 1 of 5 suicidal ideation questions: wish to be dead, and 4 different categories of active suicidal ideation. Suicidal behavior: a "yes" answer to any 1 of 5 suicidal behavior questions: preparatory acts or behavior, aborted attempt, interrupted attempt, actual attempt, and completed suicide. |
