The purpose of this study is to evaluate efficacy and safety of toludesvenlafaxine hydrochloride sustained-release tablets in the treatment of anhedonia in patients with major depression disorder compared to desvenlafaxine succinate sustained-release tablets, to provide evidence-based basis for clinical rational drug use.
The study included 80 patients with major depression disorder (aged 18 to 65 years) who meet the diagnostic criteria for depression in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Eligible patients were randomly assigned (1:1) to 8-week treatment with toludesvenlafaxine hydrochloride sustained-release tablets (n=40) or desvenlafaxine succinate sustained-release tablets(n=40), followed up at period of enrollment as baseline and at the end of 2th, 4th and 8th weeks. Adverse events were recorded.

| Snaith-Hamilton Pleasure Scale (SHAPS) Total Score | The SHAPS is a well-validated 14-item self-report questionnaire commonly used to assess anhedonia. Each item on the SHAPS is worded so that higher scores indicate greater pleasure capacity. A total score can be derived by summing the responses to each item. Each item is rated as either 0 or 1, for a total score between 0 and 14 | Baseline and the end of week 8 |

| Rating Scale for Side Effects (SERS) Score | All items in SERS adopt 4-level scoring method ranging from 0 to 3 points, and the standard of each item is as follows :0 indicates none, 1 indicates mild, 2 indicates moderate and 3 indicates severe. Two evaluation scales are required for each symptom. The first is the spontaneous reporting of patients when answering questions. The second is what the evaluator observed. The evaluator needs to systematically ask about each symptom. |

| Snaith-Hamilton Pleasure Scale (SHAPS) Reductive Rate | SHAPS Reductive Rate(%) = (pre-treatment score - post-treatment score)/pre-treatment score ×100%. | The end of Week 2, 4 and 8 |
| Dimensional Anhedonia Rating Scale (DARS) Score | DARS is a 17-item self-report questionnaire that is designed to assess anhedonia in major depressive disorder (MDD), and particularly to increase scale generalizability while maintaining specificity. Respondents provide their own examples of rewarding experiences across the domains of hobbies, social activities, food/drink, and sensory experience. Participants answer a set of standardized questions about desire, motivation, effort, and consummatory pleasure with a recall period of "right now" for the examples provided. The instrument is scored as a total sum of all items (range 0-68) with higher scores reflecting increased motivation, effort and pleasure (that is, less anhedonia). | Baseline, the end of Week 2, 4 and 8 |
| Montgomery-Asberg Depression Rating Scale (MADRS) Score | The MADRS is a clinician-rated scale designed to measure depression severity and detects changes due to antidepressant treatment. The scale consists of 10 items, each of which is scored from 0 (item not present or normal) to 6 (severe or continuous presence of the symptoms), for a total possible score of 60. Higher scores represent a more severe condition. | Baseline, the end of Week 2, 4 and 8 |
| 17-item Hamilton Depression Rating Scale (HAM-D17) Score | HAM-D17 has been the gold standard for the assessment of depression. The score needs to be based on clinical interviews, and the time frame of the assessment is usually the situation in the previous week. Most items use a 5-point scale of 0 to 4. The standard of each level is: 0 indicates none, 1 indicates mild, 2 indicates moderate, 3 indicates severe, and 4 indicates extremely severe. A few items adopt the 3-level scoring method with 0~2 points, and the grading standard is: 0 indicates none, 1 indicates mild to moderate and 2 indicates severe. | Baseline, the end of Week 2, 4 and 8 |
| Sheehan Disability Scale (SDS) Score | SDS is composed of three self-rating dimensions, which assess functional status in work, social life/leisure activities, and family life/family responsibilities. Each dimension is scored on a scale of 0 to 10, with 1 to 3 indicating mild impairment, 4 to 6 indicating moderate impairment, 7 to 9 indicating significant impairment, and 10 indicating extreme severity. The three dimensions can also be added together to reflect the overall functional deficiency. The score ranges from 0 to 30, with 0 indicating no damage and 30 indicating significant damage. | Baseline, the end of Week 2, 4 and 8 |
| Quality of Life Enjoyment and Satisfaction Questionnaire Short Form (Q-LES-Q-SF) Score | Q-LES-Q-SF consists of 16 self-rated items. Each item is divided into five grades: 1 indicates very dissatisfied, 2 indicates dissatisfied, 3 indicates average, 4 indicates satisfied, and 5 indicates very satisfied. The higher the score, the better the happiness and quality of life satisfaction of the subjects. The first 14 items are used to generate an overall score, while the remaining 2 items are individual items that measure satisfaction and overall quality of life related to the study drug. | Baseline, the end of Week 2, 4 and 8 |
| The end of Week 2, 4 and 8 |
| Arizona Sexual Experience Scale (ASEX) Score | ASEX is designed to assess aspects of psychotropic drug-induced sexual dysfunction: drive, arousal, penile erection/vaginal lubrication, ability to reach orgasm, and satisfaction from orgasm. The ASEX can be self- or clinician-administered. The 5 questions are rated using 6-point Likert-type scales with varying endpoints. Possible total scores range from 5 to 30, with the higher scores indicating more sexual dysfunction. | Baseline, the end of Week 2, 4 and 8 |
