Registered outcomes2
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Change from Baseline to Week 6 in the Montgomery Asberg Depression Rating Scale (MADRS) total score | Baseline and up to Week 6 | The MADRS is a 10-item, clinician-rated scale that evaluates the participant's depressive symptomatology during the past week. Participants are rated on items assessing feelings of sadness, lassitude, pessimism, inner tension, suicidality, reduced sleep or appetite, difficulty in concentration, and lack of interest. Each item will be scored on a 7-point scale with a score of 0 reflecting no symptoms and a score of 6 reflecting symptoms of maximum severity. Thus, scores in the MADRS range from 0 to 60, with increasing scores indicating increasing severity. |
| Secondary | Change from Baseline to Week 6 assessed in the Snaith-Hamilton Pleasure Scale (SHAPS) total score | Baseline and up to Week 6 | The SHAPS is a 14 item participant-reported instrument which measures anhedonia. It has been shown to be valid and reliable in normal and clinical samples, with adequate construct validity, satisfactory test-retest reliability and high internal consistency. The scale will be completed by the participant and reviewed by site personnel qualified to oversee completeness. Each of the 14 items has a set of 4 responses, 2 of which endorse agreement (Definitely Agree, Agree) and 2 of which endorse disagreement (Disagree, Strongly Disagree). A total score can be derived by summing the response items, where those answered with "strongly agree" will be coded as a 1, while a "strongly disagree" response will be coded as 4. Therefore, scores on the SHAPS can range from 14 to 56, with higher scores corresponding to higher levels of anhedonia. |
