NCT ID: NCT01979133

Last Updated: 2017-04-19

Results Overview

HAMD is an observer-rated measure of depressive symptomatology: 1. 17 questions (answers for individual questions range between 0-3 and 0-4). Total score range: 0-52. No subscales for this measure. 2. 0 - no depression; 52 - very severe depression (lower score corresponds to a better outcome). 3. Total score is obtained by summing questions 1-17.

Measure
Icariin
Icariin will be given 100 mg/day. A dose titration from 100 mg/day to 200 mg/day will be allowed at week 3 for participants with less than a 30% reduction in HAMD and/or still using cocaine or alcohol or have a positive urine drug screen. An additional dose titration to 300 mg/day will be allowed at week 6 for participants with less than a 50% reduction in HAMD scores and/or still using cocaine or alcohol or have a positive urine drug screen. Icariin: Participants will receive 20% icariin (100 mg/day) in a commercially available over-the-counter Horny Goat Weed supplement. A dose titration from 100 mg/day to 200 mg/day will be allowed at week 3 participants with less than a 30% reduction in HAMD and/or still using cocaine or alcohol or have a positive urine drug screen. An additional dose titration to 300 mg/day will be allowed at week 6 for participants with less than a 50% reduction in HAMD scores and/or still using cocaine or alcohol or have a positive urine drug screen.

PRIMARY outcome

Timeframe: Baseline vs. Week 8 (Exit)

Population: The total enrollment goal was 10. One participant dropped out during the baseline II visit, thus week 8 score was not obtained for that participant and the change from baseline to week 8 could not be collected. Thus, the analysis includes 9 participants instead of proposed 10.

Population: The planned enrollment was 10 participants. One participant dropped out during Baseline II visit, thus researchers were unable to assess change from baseline to week 8 in this participant. As a results, the overall number of participants analyzed was 9.

HAMA is a 14-item observer rated measure of anxiety symptomatology: 1. 14 items in a scale, no subscales. Individual items are score 0 (no anxiety) to 4 (very severe anxiety). 2. Total scores range from 0-56. 3. Total scores represent more severe anxiety. Lower scores represent a better outcome.

The QIDS is a 16-item self-report measure of depressive symptomatology: 1. 16 items rated on a scale from 0-3. No subscales for this instrument. 2. Total score range is 0-27, where higher score represents higher levels of depression. Lower scores associated with better outcomes. 3. Total score is obtained using the following formula: highest score on items 1-4 + item 5 + highest score on items 6-9 + item 10+item 11+item12+item13+item14+highest score on items 15-16

Population: The planned enrollment was 10 participants. One participant dropped out during Baseline II visit, thus researchers were unable to assess change from baseline to week 8 in this participant. As a result, the overall number of participants included in the analysis was 9.

1. Participants are asked to identify the number of alcoholic drinks they consumed on each day within the last 7 days from the day of visit (not including the day of visit). Participants are asked to provide alcohol name and the amount of alcohol they consumed. These values are then converted to standard drinks using a standard drinks calculator. 2. The minimum number of drinks per week is 0. There is no maximum number of drinks per week, as the maximum number is unique to each participant. 3. The general convention for standard drinks used in this study is as follows (oz per one standard drink): * beer: 12 fl oz (5% ABV) * wine: 5 fl oz (10-12% ABV or 18-20% ABV for fortified wine) * hard liquor: 1.5 fl oz (40% ABV)

1. Heavy drinking day is defined as 5 standard drinks per day for men, and 4 standard drinks per day for women. 2. Minimum score is 0 (no drinks); maximum score is unique to each individual participant. Lower score represents a better outcome. 3. Average number of heavy drinking days per week is calculated by asking participants to identify the number of drinks they had on each day during the past 7 days (not including the day of visit). 4. See outcome measure description for "standard drinks per week" for standard drinks convention.

1. Total score range is 0-7 (no days of alcohol use - 7 days of alcohol use). The lower score represents better outcome. 2. Participants are asked to identify days on which they used alcohol in the past week (not including the day of visit).

The YMRS is an 11-item observer-rated measure of mania symptomatology: 1. 7 individual items are scored between 0-4. 2. 4 individual items are scored between 0-8. 3. Total score range is 0-60, with no subscales. Higher score is indicative of more manic symptoms. Lower score represents better outcomes. 4. Total score is obtained by adding items on the scale together.
