Outcome Measures
| 1. Primary: | Average Change of the MADRS (Montgomery-Asberg Depression Rating Scale) Total Score From Baseline to Final Visit After 12 Weeks of Treatment [ Baseline and Week 12 ] |
| 2. Secondary: | Average Change of the MADRS (Montgomery-Asberg Depression Rating Scale) Total Score From Baseline to Final Visit After 12 Weeks of Treatment in Participants With Signs of at Least Moderate Depression (MADRS Score: >=18) [ Baseline and Week 12 ] |

Hide Outcome Measure 3| Measure Type | Secondary |
|---|---|
| Measure Title | Average Change of the HAM-D (Hamilton Depression Rating Scale, 17-item-Version) Total Score From Baseline to Final Visit After 12 Weeks of Treatment |
| Measure Description | The Hamilton Rating Scale for Depression contains 17 questions which detect change and measure illness severity. Individual items are rated on a scale of 0-4, 0-3, and 0-2 with total HAMD score range from 0 (not ill) to 54 (severely ill). |
| Time Frame | Baseline and Week 12 |
| Safety Issue | No |
| Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate. |
|---|
| Modified Intent to Treat (mITT): All treated patients with MADRS score at baseline and post baseline (i.e., at visit 4 and/or 5). The High/Low HAM-D scores for this population were 27/5. |
| Description | |
|---|---|
| Ropinirole | Subjects who were treated on day 1-2 with 0.25 mg/day of ropinirole and on days 3-7 0.5 mg for 12 weeks if tolerated. After two weeks, dose could be increased weekly by 0.5mg a day up to 4 mg maximum dose. |
