Patient Resources for

Postpartum Depression (PPD)

Postpartum Depression (PPD) can affect a mother’s ability to care for her child and may negatively affect a child’s cognitive development. PPD is thought to develop from rapid changes in the levels of endogenous neurosteroids during pregnancy.

Plasma levels of allopregnanolone, which is a metabolite of progesterone and GABA modulator, are known to increase throughout pregnancy and then precipitously drop after delivery. It is thought that these rapid hormonal changes are linked to triggering depression in women who are vulnerable to develop this condition.

The most common medications prescribed to women who seek treatment for PPD are SSRI’s and SNRI’s, which have limited evidence of efficacy. There are currently no approved therapies to treat PPD.

How does PPD affect the body?

PPD is a mood disorder that affects about 15% of women within the first year of childbirth. Women with PPD experience feelings of extreme sadness, hopelessness, suicidal ideation, anxiety, and fatigue. These symptoms mirror those of a major depressive episode with the additional criteria that the onset of depression occurs within 4 weeks of childbirth. PPD can affect a mother’s ability to care for her child and may negatively affect a child’s cognitive development.

Clinical Development of Ganaxolone in Postpartum Depression

The Magnolia study is a Phase 2 double-blind, placebo-controlled, multiple-dose escalation study to evaluate the safety, pharmacokinetics and efficacy of intravenous (IV) ganaxolone in women with postpartum depression (PPD). The study consists of multiple cohorts of women with a Hamilton Depression Rating Scale (HAM-D17) score ≥26. Patients randomized into the first part of the study underwent an infusion (IV) of either ganaxolone or placebo and were followed for 30 days. Data from the best performing cohort showed a clinically meaningful 5.6-point reduction in HAM-D17 compared to placebo at 48 hours that was durable through the last visit, day 34. 75% of patients were responders, as defined as having a ≥50% reduction from baseline, at day 34 and 67% were responders at 60 hours. 50% of patients achieved remission from depression, as determined by a HAM-D17 ≤7, at day 34 and 33% achieved remission at 60 hours. Ganaxolone was safe and well-tolerated in all dose groups. Consistent with previous ganaxolone studies, the most common reported adverse events were sedation and dizziness. There were no serious adverse events reported, no discontinuations due to a treatment related adverse event and, consistent with prior studies, there were no reports of syncope or loss of consciousness.

Patients are being enrolled in the second part of the Magnolia Study which will evaluate a short IV infusion followed by oral ganaxolone, allowing the new mother to remain home during the important bonding time with her new child.

Enrollment is also ongoing in the Amaryllis study, a Phase 2 clinical trial to evaluate the safety, tolerability and efficacy of oral ganaxolone in women with PPD. The study is designed to enroll approximately 50 women at 20 sites within the US. The goal of this study is to determine the oral dosing regimen for future studies. Data from the most recent dose cohort who took oral ganaxolone (n=18) for four weeks had a mean HAM-D17 reduction of 13.2 points at 28 days and 15.7 points at day 36. As with IV, oral ganaxolone was generally safe and well-tolerated with no serious adverse events reported and no discontinuations due to treatment related adverse events. 

TARGET FORMULATIONS

Recent studies conducted in women with PPD showed that both oral and IV ganaxolone were safe, well-tolerated and effective in reducing PPD.  The goal with developing multiple dose forms is to provide a dose regimen that is fast acting, durable and convenient, thereby eliminating an overnight hospital stay.
