A Phase 2 interventional study of Ganaxolone and Placebo in Depression, Depressive Disorder and Depression, Postpartum, sponsored by Marinus Pharmaceuticals. Completed at 16 sites in United States. Open to female participants aged 18 Years to 45 Years. Per ClinicalTrials.gov, last updated 2023-07-19.
Sponsored by Marinus Pharmaceuticals · Phase 2, Interventional, and Treatment
This study will evaluate the Safety, Pharmacokinetics and Efficacy of IV Administration of Ganaxolone in Women with Postpartum Depression
This study will explore whether ganaxolone is safe and well tolerated in women suffering from PPD. In addition, ganaxolone's efficacy in treating depressive symptoms will be assessed through a set of exploratory analyses. Plasma levels of ganaxolone will be determined through pharmacokinetic analysis. The study results will be used to select a ganaxolone dose and dosing regimen for further development in PPD.

Change From Baseline in Hamilton Depression Rating Scale 17-item Version (HAMD17) 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. 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

Change From Baseline in Edinburgh Postnatal Depression Scale (EPDS) Total Score
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
Change From Baseline in Spielberger State-Trait Anxiety Inventory 6-item Version (STAI6) Total Score
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
