A Clinical Trial of Intravenous (IV) Ganaxolone in Women With Postpartum Depression

The HAMD17 was a 17-item clinician-rated instrument used to assess the range of symptoms that were most frequently observed in participants with major depression. All items were scored on an ordinal scale between 0 and 4 (8 items) or 0 and 2 (9 items) of increasing severity. Each of 17 items was rated by clinician with rating of 0: absent, 1: doubtful to mild, 2: mild to moderate, 3: moderate to severe, and 4: very severe. A total score (0 to 52) was calculated by adding scores of all 17 items, where 0 indicated no depression and 52 indicated severe depression. Higher score represented more severe condition. Baseline was defined as the Day 1 assessment before study drug infusion. Change from Baseline was calculated by subtracting Baseline value from the post-dose visit value.

Time frame: Baseline and Day 3 post-infusion (60 hours post start of infusion) for Cohorts 1 to 3 and Baseline and Day 29 for Cohort 6

Population: Modified intent-to-treat (mITT) population: Included all participants in the safety set who had ≥1 post-randomization efficacy assessment. Only those participants with data available at the specified data points were analyzed.

The EPDS is a validated 10-question depression assessment for postpartum women, which includes anxiety symptoms and excludes constitutional symptoms associated with depression common in the postpartum period, such as changes in sleeping patterns. It consists of 10 multiple choice questions with scores for each question ranging from 0-3. Questions 1, 2, & 4 are scored 0, 1, 2 or 3 with top box scored as 0 and the bottom box scored as 3. Questions 3 and 5 to 10 are reverse scored, with the top box scored as a 3 and the bottom box scored as 0. Scores are then summed for a total score, which ranges from 0: no depression to 30: severe depression. Higher score indicates severe depression. Baseline was defined as the Day 1 assessment before study drug infusion. Change from Baseline was calculated by subtracting Baseline value from the post-dose visit value.

Time frame: Baseline, Day 1, Day 2, Day 3 post-infusion (60 hours post start of infusion), Day 8, Day 11, Day 15, Day 22, Day 29, Day 34, Day 36, Day 57 and Day 71

Population: mITT population. Only those participants with data available at the specified data points were analyzed.

Time frame: Baseline, Day1 post-infusion(6hours post start of infusion), Day1(12hours post start of infusion), Day2(24hours post start of infusion),Day3 post-infusion(48hours post start of infusion),Day4(72hours post start of infusion),Days 8,11,15,22,36,57 and 71

Population: mITT population. Only those participants with data available at the specified data points were analyzed.

The STAI6 is a 6-item self-rated instrument used to assess anxiety state. The STAI6 questions included: 1. I feel calm; 2. I am tense; 3. I feel upset; 4. I am relaxed; 5. I feel content; 6. I am worried. Each of these questions were rated as: a) not at all; b) somewhat; c) moderately; d) very much. For questions 2, 3, and 6, the scoring was a = 1, b = 2, c = 3, and d = 4. For the other 3 questions, the scoring was a = 4, b = 3, c = 2, and d = 1. The STAI6 score was the result of first totaling the 6 individual item scores, and then prorating by a multiplication factor of 20/6 to acquire a score range of 20 (low anxiety) to 80 (high anxiety). Higher score indicated higher level of anxiety. Baseline was defined as the Day 1 assessment before study drug infusion. Change from Baseline was calculated by subtracting Baseline value from the post-dose visit value.

Time frame: Baseline, Day 1 (12 hours post start of infusion), Day 2, Day 3 post-infusion (60 hours post start of infusion), Day 4, Day 8, Day 11, Day 15, Day 22, Day 29, Day 34, Day 36, Day 57 and Day 71

Population: mITT population. Only those participants with data available at the specified data points were analyzed.

HAMD17 Remission was defined as total score ≤7. The HAMD17 was a 17-item clinician-rated instrument used to assess the range of symptoms that were most frequently observed in participants with major depression. All items were scored on an ordinal scale between 0 and 4 (8 items) or 0 and 2 (9 items) of increasing severity. Each of 17 items was rated by clinician with rating of 0: absent, 1: doubtful to mild, 2: mild to moderate, 3: moderate to severe, and 4: very severe. A total score (0 to 52) was calculated by adding scores of all 17 items, where 0 indicated no depression and 52 indicated severe depression. Higher score represented more severe condition. Number of participants with HAMD17 remission is presented

Time frame: Day1 post-infusion (6 hours post start of infusion [SOI]), Day 1 (12 hours post SOI), Day2 (24 hours post SOI), Day 3 post-infusion (48 hours post SOI), Day 3 post-infusion (60 hours post SOI), Day 4 (72 hours post SOI), Days 8,11,15,22,29,34,57 and 71

Population: mITT population. Only those participants with data available at the specified data points were analyzed.

HAMD17 Response was defined as ≥50% reduction from Baseline in total score. The HAMD17 was a 17-item clinician-rated instrument used to assess the range of symptoms that were most frequently observed in participants with major depression. All items were scored on an ordinal scale between 0 and 4 (8 items) or 0 and 2 (9 items) of increasing severity. Each of 17 items was rated by clinician with rating of 0: absent, 1: doubtful to mild, 2: mild to moderate, 3: moderate to severe, and 4: very severe. A total score (0 to 52) was calculated by adding scores of all 17 items, where 0 indicated no depression and 52 indicated severe depression. Higher score represented more severe condition.

The CGI-I scale is a clinician-rated 7-point scale used to assess how much the participant's illness had improved or worsened relative to a Baseline state at the beginning of the intervention. It was rated as: 1. very much improved; 2. much improved; 3. minimally improved; 4. no change; 5. minimally worse; 6. much worse; 7. very much worse. Higher scores indicated worse condition. Response was defined as \>50% decrease from Baseline in CGI-I total score.
