Abstract
Studies in the 1980s revealed endogenous metabolites of progesterone and deoxycorticosterone to be potent, efficacious, positive allosteric modulators (PAMs) of the GABAA receptor (GABAA R). The discovery that such steroids are locally synthesised in the central nervous system (CNS) promoted the thesis that neural inhibition in the CNS may be "fine-tuned" by these neurosteroids to influence behaviour. In preclinical studies, these neurosteroids exhibited anxiolytic, anticonvulsant, analgesic and sedative properties and, at relatively high doses, induced a state of general anaesthesia, a profile consistent with their interaction with GABAA Rs. However, realising the therapeutic potential of either endogenous neurosteroids or synthetic "neuroactive" steroids has proven challenging. Recent approval by the Food and Drug Administration of the use of allopregnanolone (brexanolone) to treat postpartum depression has rekindled enthusiasm for exploring their potential as new medicines. Although neurosteroids are selective for GABAA Rs, they exhibit little or no selectivity across the many GABAA R subtypes. Nevertheless, a relatively minor population of receptors incorporating the δ-subunit (δ-GABAA Rs) appears to be an important contributor to their behavioural effects. Here, we consider how neurosteroids acting upon GABAA Rs influence neuronal signalling, as well as how such effects may acutely and persistently influence behaviour, and explore the case for developing selective PAMs of δ-GABAA R subtypes for the treatment of psychiatric disorders.

Abstract
Neurosteroids are involved in the pathophysiology of many neuroendocrine disorders in women. This review describes recent advancements in pharmacology of neurosteroids and emphasizes the benefits of neurosteroid replacement therapy for the management of neuroendocrine disorders such as catamenial epilepsy (CE), postpartum depression (PPD) and premenstrual brain conditions. Neurosteroids are endogenous modulators of neuronal excitability. A variety of neurosteroids are present in the brain including allopregnanolone (AP), allotetrahydro-deoxycorticosterone and androstanediol. Neurosteroids interact with synaptic and extrasynaptic GABAA receptors in the brain. AP and related neurosteroids, which are positive allosteric modulators of GABAA receptors, are powerful anticonvulsants, anxiolytic, antistress and neuroprotectant agents. In CE, seizures are most often clustered around a specific menstrual period in women. Neurosteroid withdrawal-linked plasticity in extrasynaptic receptors has been shown to play a key role in catamenial seizures, anxiety and other mood disorders. Based on our extensive research spanning two decades, we have proposed and championed neurosteroid replacement therapy as a rational strategy for treating disorders marked by neurosteroid-deficiency, such as CE and other related ovarian or menstrual disorders. In 2019, AP (renamed as brexanolone) was approved for treating PPD. A variety of synthetic neurosteroids are in clinical trials for epilepsy, depression and other brain disorders. Recent advancements in our understanding of neurosteroids have entered a new era of drug discovery and one that offers a high therapeutic potential for treating complex brain disorders.

The imidazodiazepine, KRM-II-81: An example of a newly emerging generation of GABAkines for neurological and psychiatric disorders. Pharmacol Biochem Behav 2022; 213:173321. [PMID: 35041859 DOI: 10.1016/j.pbb.2021.173321] [Citation(s) in RCA: 30] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2021] [Revised: 12/21/2021] [Accepted: 12/30/2021] [Indexed: 02/07/2023]
Abstract
GABAkines, or positive allosteric modulators of γ-aminobutyric acid-A (GABAA) receptors, are used for the treatment of anxiety, epilepsy, sleep, and other disorders. The search for improved GABAkines, with reduced safety liabilities (e.g., dependence) or side-effect profiles (e.g., sedation) constituted multiple discovery and development campaigns that involved a multitude of strategies over the past century. Due to the general lack of success in the development of new GABAkines, there had been a decades-long draught in bringing new GABAkines to market. Recently, however, there has been a resurgence of efforts to bring GABAkines to patients, the FDA approval of the neuroactive steroid brexanolone for post-partum depression in 2019 being the first. Other neuroactive steroids are in various stages of clinical development (ganaxolone, zuranolone, LYT-300, Sage-324, PRAX 114, and ETX-155). These GABAkines and non-steroid compounds (GRX-917, a TSPO binding site ligand), darigabat (CVL-865), an α2/3/5-preferring GABAkine, SAN711, an α3-preferring GABAkine, and the α2/3-preferring GABAkine, KRM-II-81, bring new therapeutic promise to this highly utilized medicinal target in neurology and psychiatry. Herein, we also discuss possible conditions that have enabled the transition to a new age of GABAkines. We highlight the pharmacology of KRM-II-81 that has the most preclinical data reported. KRM-II-81 is the lead compound in a new series of orally bioavailable imidazodiazepines entering IND-enabling safety studies. KRM-II-81 has a preclinical profile predicting efficacy against pharmacoresistant epilepsies, traumatic brain injury, and neuropathic pain. KRM-II-81 also produces anxiolytic- and antidepressant-like effects in rodent models. Other key features of the pharmacology of this compound are its low sedation rate, lack of tolerance development, and the ability to prevent the development of seizure sensitization.

Abstract
Rapid antidepressant effects of S-ketamine have repeatedly been confirmed in patients with depression, as well as in chronic unpredictable mild stress (CUMS) animal models. However, the pharmacological study of S-ketamine for anti-postpartum depression has not been considered. In this study, the classical method of reproductive hormone withdrawal was used to construct a rat model of postpartum depression (PPD). Subsequently, the study evaluated the effects of low-dose S-ketamine on behavior and synaptic plasticity, which is related to depression, in the hippocampus of PPD rats. Multiple behavioral tests were used to evaluate depression-like behaviors in PPD models. Synaptic plasticity of the hippocampus can be demonstrated by Western blot, Golgi staining, transmission electron microscopy, and electrophysiological recording. Our study provides insight into the role of low-dose S-ketamine in antidepressant as well as antianxiety and indicates that maintaining synaptic plasticity is a key target for S-ketamine therapy for postpartum depression induced by reproductive hormone withdrawal.

Abstract
Postpartum depression is one of the most common morbidities of childbearing, yet it is underdiagnosed and undertreated with negative consequences for mother and offspring. Despite the widespread use of standard-of-care antidepressants as the mainstay of treatment for postpartum depression, there is limited evidence on their safety and efficacy due to their slow onset of action and suboptimal outcomes. The emergence of gamma-aminobutyric acidergic neuroactive steroids may offer faster response and remission times and improved patient outcomes. This article reviews the evidence base for the efficacy of standard-of-care antidepressants, hormonal therapeutics including progestins and estradiol, and gamma-aminobutyric acidergic neuroactive steroids in the treatment of postpartum depression, as well as the safety of infant exposure to these agents during lactation.

Abstract
Sex differences in the rates of affective disorders have been recognized for decades. Studies of physiologic sex-related differences in animals and humans, however, have generally yielded little in terms of explaining these differences. Furthermore, the significance of these findings is difficult to interpret given the dynamic, integrative, and highly context-dependent nature of human physiology. In this article, we provide an overview of the current literature on sex differences as they relate to mood disorders, organizing existing findings into five levels at which sex differences conceivably influence physiology relevant to affective states. These levels include the following: brain structure, network connectivity, signal transduction, transcription/translation, and epigenesis. We then evaluate the importance and limitations of this body of work, as well as offer perspectives on the future of research into sex differences. In creating this overview, we attempt to bring perspective to a body of research that is complex, poorly synthesized, and far from complete, as well as provide a theoretical framework for thinking about the role that sex differences ultimately play in affective regulation. Despite the overall gaps regarding both the underlying pathogenesis of affective illness and the role of sex-related factors in the development of affective disorders, it is evident that sex should be considered as an important contributor to alterations in neural function giving rise to susceptibility to and expression of depression.

Abstract
Neuroactive steroids have rapid, nongenomic effects on neuronal excitability. The effects in humans are less clear. We compared seizure control and concentrations of neuroactive steroids, known to influence neuroexcitability in animal studies, in pregnant women. Participants were prospectively followed throughout pregnancy with seizure-medication diaries and blood samples, assayed for steroid concentrations with gas chromatography-mass spectrometry. Baseline seizure frequency was calculated for the preconception year, and it was determined if seizure frequency was increased in each trimester. The Wilcoxon rank-sum test was used to compare neuroactive steroid concentrations in between the group with increased frequency to the group without, as calculated for the respective trimester, with the Holm-Bonferroni method to correct for multiple comparisons. Among eighty-three pregnancies included, twenty-eight had increased seizure frequency during at least one trimester (15, 18 and 10, respectively) compared to preconception seizure frequency. Allopregnanolone concentrations were lower in the 3rd trimester (p < 0.001), with a similar trend in the 1st (p = 0.08), for pregnancies with increased compared to those with stable seizure frequency. Other neuroactive steroid concentrations were similar. Our findings suggest that lower allopregnanolone concentrations are associated with increased seizure frequency during pregnancy. Validation of these finding in a larger cohort has potential important clinical applications.

Abstract
Progesterone (P4) can be metabolized to two general classes of neuroactive steroids (NAS) -those like allopregnanolone (ALLO) and pregnanolone (PA) which are positive allosteric modulators of the Gamma Aminobutyric Acid type A (GABAA) receptor and those like isoallopregnanolone (ISOALLO) and epipregnanolone (EPI) which are negative allosteric modulators of the GABAA receptor. While exogenous administration of ALLO is effective in treating postpartum depression, knowledge gaps remain in the dynamic interplay of NAS across the perinatal period. In particular little is known about ALLO and PA in relation to depression earlier in pregnancy, and the role of ISOALLO and EPI in relation to depression at any point in the perinatal period. In a prospective, nested case/control study in low-income women of color, we compared the metabolism of P4 to four NAS (i.e., ratios ALLO:P4, PA:P4, ISOALLO:P4, EPI:P4) in pregnant women with depression at either or both of the first and second trimesters (cases) and women without depression at either time point (controls). Fifty women (36% depressed, 56% Black, 28% Latina) completed depression screening using a computerized adaptive test of mental health (CAT-MH™) and provided blood serum samples in both trimesters. In longitudinal mixed effects models of both trimesters, PND cases showed higher ratios of ALLO:P4 (p = .002) and PA:P4 (p = .03) compared to controls. In regression models of only first trimester data, there was no significant difference in NAS ratios between cases and controls (p > .05). Conversely, in models of the second trimester, ratios of PA:P4 (p = .002) and ISOALLO:P4 (p = .01) were significantly higher in cases compared to controls, and ratios of ALLO:P4 (p = .08) and EPI:P4 (p = .1) also trended higher in cases. The most severe cases, those with depression at both trimesters, showed an increase in ALLO:P4 (p = .06) and EPI:P4 (p < .001) ratios from the first to the second trimester, whereas controls showed a decrease in these ratios. Secondary analyses confirmed higher levels of ALLO (p = .04) and PA (p = .07) overall in cases compared to controls, along with higher levels of PA (p = .005) and ISOALLO (p = .02) in the second trimester alone. This work suggests a dynamic relationship between NAS and PND; whereas low ALLO levels have been previously associated with postpartum depression, earlier in pregnancy a higher metabolism of P4 to ALLO (and higher ALLO levels) is associated with depression. Some women may show a hormone-sensitive depressive response to acute increases in NAS metabolism in early pregnancy.

Abstract
Major depressive disorder (MDD) is a common and severe mental disorder that is usually recurrent and has a high risk of suicide. This disorder manifests not only with psychological symptoms but also multiple changes throughout the body, including increased risks of obesity, diabetes, and cardiovascular disease. Peripheral markers of oxidative stress and inflammation are elevated. MDD is therefore best described as a multisystem whole-body disease. Pharmacological treatment with antidepressants usually requires several weeks before the desired effects manifest. Previous theories of depression, such as the monoamine or neurogenesis hypotheses, do not explain these characteristics well. In recent years, new mechanisms of action have been discovered for long-standing antidepressants that also shed new light on depression, including the sphingolipid system and the receptor for brain-derived neurotrophic factor (BDNF).

Abstract
Importance Postpartum depression (PPD) is one of the most common medical complications during and after pregnancy, negatively affecting both mother and child. Objective To demonstrate the efficacy and safety of zuranolone, a neuroactive steroid γ-aminobutyric acid receptor-positive allosteric modulator, in PPD. Design, Setting, and Participants This phase 3, double-blind, randomized, outpatient, placebo-controlled clinical trial was conducted between January 2017 and December 2018 in 27 enrolling US sites. Participant were women aged 18 to 45 years, 6 months or fewer post partum, with PPD (major depressive episode beginning third trimester or ≤4 weeks postdelivery), and baseline 17-item Hamilton Rating Scale for Depression (HAMD-17) score of 26 or higher. Analysis was intention to treat and began December 2018 and ended March 2019. Interventions Randomization 1:1 to placebo:zuranolone, 30 mg, administered orally each evening for 2 weeks. Main Outcomes and Measures Primary end point was change from baseline in HAMD-17 score for zuranolone vs placebo at day 15. Secondary end points included changes from baseline in HAMD-17 total score at other time points, HAMD-17 response (≥50% score reduction) and remission (score ≤7) rates, Montgomery-Åsberg Depression Rating Scale score, and Hamilton Rating Scale for Anxiety score. Safety was assessed by adverse events and clinical assessments. Results Of 153 randomized patients, the efficacy set comprised 150 patients (mean [SD] age, 28.3 [5.4] years), and 148 (98.7%) completed treatment. A total of 76 patients were randomized to placebo, and 77 were randomized to zuranolone, 30 mg. Zuranolone demonstrated significant day 15 HAMD-17 score improvements from baseline vs placebo (-17.8 vs -13.6; difference, -4.2; 95% CI, -6.9 to -1.5; P = .003). Sustained differences in HAMD-17 scores favoring zuranolone were observed from day 3 (difference, -2.7; 95% CI, -5.1 to -0.3; P = .03) through day 45 (difference, -4.1; 95% CI, -6.7 to -1.4; P = .003). Sustained differences at day 15 favoring zuranolone were observed in HAMD-17 response (odds ratio, 2.63; 95% CI, 1.34-5.16; P = .005), HAMD-17 score remission (odds ratio, 2.53; 95% CI, 1.24-5.17; P = .01), change from baseline for Montgomery-Åsberg Depression Rating Scale score (difference, -4.6; 95% CI, -8.3 to -0.8; P = .02), and Hamilton Rating Scale for Anxiety score (difference, -3.9; 95% CI, -6.7 to -1.1; P = .006). One patient per group experienced a serious adverse event (confusional state in the zuranolone group and pancreatitis in the placebo group). One patient in the zuranolone group discontinued because of an adverse event vs none for placebo. Conclusions and Relevance In this randomized clinical trial, zuranolone improved the core symptoms of depression as measured by HAMD-17 scores in women with PPD and was generally well tolerated, supporting further development of zuranolone in the treatment of PPD.

Abstract
BACKGROUND Brexanolone (Zulresso) is the first Federal Drug Administration-approved drug for the treatment of postpartum depression. Brexanolone is a positive allosteric modulator of the GABAA receptor and is given over 60 hours by infusion in a medical setting. This drug has been shown to be effective at significantly reducing Hamilton Rating Scale for Depression scores at 60 hours and 30 days after infusion; however, data beyond 30 days have not yet been available. There have been limited clinical programs able to offer brexanolone owing to the complexity of setting up this treatment in a medical setting. PURPOSE This study sought to obtain follow-up data from 16 patients who received a brexanolone infusion at UNC Hospitals in Chapel Hill, NC, between October 2019 and December 2020 and were beyond the 30-day postinfusion time point. We describe the methods used to successfully implement this treatment program in an academic medical center and discuss associated challenges and lessons learned with patient selection and process improvements. METHODS Hamilton Rating Scale for Depression scores were collected before and after infusion from 16 patients who received a brexanolone infusion at UNC. Patients were subsequently contacted for a follow-up interview to obtain Hamilton Rating Scale for Depression scores and complete a semistructured interview at least 30 days past treatment end (between 3 and 16 months after infusion). RESULTS All 16 patients had a significant reduction in Hamilton Rating Scale for Depression scores at 60 hours, scores dropping on average from 23.9 (standard deviation = 2.6) to 7.6 (standard deviation = 2.9). Eleven of 16 patients consented to provide follow-up data. Follow-up Hamilton Rating Scale for Depression scores remained lower than postinfusion at an average of 6.7 points (standard deviation = 5.1). CONCLUSION With a strategic cross-disciplinary approach, a Clinical Brexanolone Treatment Program was established at UNC Hospitals in 2019. Sixteen patients have been treated in the program, and 11 participated in a follow-up interview. All 11 patients gave very positive feedback about their treatment. Our program has found brexanolone to be a useful clinical tool in treating women with significant symptoms of postpartum depression.

Treating Postpartum Depression: What Do We Know about Brexanolone? Diseases 2021; 9:diseases9030052.

Abstract
Postpartum depression (PPD) is defined as the onset of major depressive disorder in mothers, occurring during pregnancy or within 4 weeks post-delivery. With 7% of pregnancy-related death in the United States owing to mental health conditions, including PPD, and a global prevalence of 12%, PPD is a growing public health concern. In 2019, the Food and Drug Administration (FDA) approved brexanolone, an exogenous analog of allopregnanolone, as the first ever drug to be specifically indicated for treating patients with PPD. This approval was preceded by an open-label study and three randomized placebo-controlled trials, each assessing the safety, tolerability, and efficacy of brexanolone, using mean Hamilton Rating Scale for Depression (HAM-D) score reduction as the primary outcome. In each randomized controlled trial, the drug was administered as an intravenous infusion given over 60 h. Enrolled participants were followed up on days 7 and 30 to evaluate the sustained effect. A statistically significant reduction in mean HAM-D score compared to placebo was observed in all three studies, supporting brexanolone's use in treating moderate-to-severe PPD. Therefore, this article attempts to briefly review the pharmacology of brexanolone, evaluate the latest available clinical data and outcomes concerning its use, reevaluate its position as a 'breakthrough' in managing PPD, and review the cost-related barriers to its worldwide standardized use.

Abstract
Objective This paper reviews the current literature available for the efficacy and safety of allopregnanolone agonists and discusses considerations for their place in therapy. Literature Search A literature search was conducted utilizing PubMed, clinicaltrials.gov, and the manufacturer's website. Data Synthesis One phase II trial and two phase III trials evaluating the efficacy and safety of brexanolone were identified. Brexanolone demonstrated efficacy through significantly reduced Hamilton Depression Rating Scale (HAM-D) scores compared to placebo in the treatment of postpartum depression (PPD). Noted adverse effects were somnolence and dizziness, excessive sedation, and loss of consciousness. One published phase II study and the interim results of two phase III trials and one phase II trial on zuranolone were included in this review. Zuranolone, an oral allopregnanolone agonist, is given as a single, 14-day course. A significant reduction in HAM-D scores was demonstrated in patients with major depressive disorder (MDD) at 15 and 28 days compared to placebo. Interim results for zuranolone in PPD and bipolar disorder (BPD) show promising reductions in HAM-D scores. Adverse effects included sedation, dizziness, and headache. Place in Therapy Allopregnanolone agonists seem to have a role in PPD when weighing the quick onset of action and potential risks of untreated PPD. The class of medications is limited by the single course for this indication and may fit as a bridge to maintenance therapy with selective serotonin reuptake inhibitors (SSRIs). Brexanolone, specifically, is hindered by the long infusion time, hospitalization associated with administration, and risk evaluation and mitigation strategy program. Zuranolone may also have a role in MDD or BPD, but more data are needed. Conclusion Allopregnanolone agonists present a novel mechanism of action in the treatment of depressive disorders. Clinical trials and interim results support significant reductions in depression scores for brexanolone in PPD, and for zuranolone in PPD, MDD, and BPD.

Abstract
Prevention of postpartum depression (PPD) is important because it typically has a 13% prevalence rate, impactful immediate symptoms with greater risk of suicide, and higher long-term risk of psychiatric symptoms in both the mother and family. There are no universal approaches across all childbearing women that have proven to be preventative for PPD, so it is hoped that dietary and/or hormonal interventions will be developed. There are some effective preventative approaches for PPD, such as psychotherapy and medical management, for the highest risk cases, like when there is a past history of a major depressive episode. The purpose is to review studies that assess dietary and hormonal interventions for prevention of PPD and/or postpartum blues, a high-risk state for PPD. Studies that assess dietary and hormonal interventions for prevention of PPD which included a comparison group were reviewed, including omega-3 fatty acids, mineral and vitamin supplements, amino acid combinations, allopregnanolone, progesterone, and thyroxine. Presently, development of dietary supplements and hormonal products for prevention of PPD is at an early stage with most trials showing results that are either preliminary, not definitive, trend level or variable across studies. Even so, a few directions are not recommended for further investigation such as progesterone and thyroxine. On the other hand, studies of allopregnanolone for prophylaxis of PPD are needed. Also, given the number of trend level findings and the multifactorial etiology of PPD, it may be prudent to investigate combined interventions rather than monotherapies. There is still a major need to develop a dietary supplement that creates resiliency against the biological changes in early postpartum associated with risk for mood disorders and/or PPD.

Abstract
On March 19, 2019, Brexanolone (Zulresso ™) was released as the first-ever FDA-approved medication specifically for the treatment of postpartum depression by Sage Therapeutics, Inc. Unfortunately, its use in breastfeeding mothers was not evaluated and is being restricted. An efficacious drug for postpartum depression stands to benefit many families. However, the lack of guidance for breastfeeding patients, and the resultant restrictions on breastfeeding by insurance companies is deeply troubling. Conversely, withholding this medication from a lactating mother is ethically problematic. From a public health perspective, we aim to foster continuous breastfeeding among depressed women while they are being treated for depression. We therefore aim to address concerns about Brexanolone's effects on the breastfed child, as exposed through breastmilk, as well as the impact this medication may have on lactation.

Abstract
The neuroactive steroid allopregnanolone (ALLO) is an endogenous positive allosteric modulator of GABA type A receptor (GABAAR), and the down-regulation of its biosynthesis have been attributed to the development of mood disorders, such as depression, anxiety and post-traumatic stress disorder (PTSD). ALLO mediated depression/anxiety involves GABAergic mechanisms and appears to be related to brain-derived neurotrophic factor (BDNF), dopamine receptor, glutamate neurotransmission, and Ca2+ channel. In the clinical, brexanolone, as a newly developed intravenous ALLO preparation, has been approved for the treatment of postpartum depression (PPD). In addition, traditional antidepressants such as selective serotonin reuptake inhibitor (SSRI) could reverse ALLO decline. Recently, the translocation protein (TSPO, 18 kDa), which involves in the speed-limiting step of ALLO synthesis, and ALLO derivatization have been identified as new directions for antidepressant therapy. This review provides an overview of ALLO researches in animal model and patients, discusses its role in the development and treatment of depression/anxiety, and directs its therapeutic potential in future.

Abstract
Background SAGE-217, a novel γ-aminobutyric acid A (GABAA) receptor positive allosteric modulator, was evaluated in phase I, double-blind, placebo-controlled, single ascending dose (SAD) and multiple ascending dose (MAD) studies to assess the safety and pharmacokinetics (PK) of SAGE-217 following administration as an oral solution. Methods In the SAD study, subjects were randomized 6:2 to a single dose of SAGE-217 or placebo. Doses ranged from 0.25 to 66 mg across nine cohorts. In the MAD study, subjects were randomized 9:3 and received SAGE-217 (15, 30, or 35 mg) or placebo once daily for 7 days. In both studies, PK, maximum tolerated dose (MTD; against predetermined criteria), safety, and tolerability were assessed. Results A total of 108 healthy volunteers enrolled in the studies—72 subjects in the SAD study and 36 subjects in the MAD study. SAGE-217 was orally bioavailable, with a terminal-phase half-life of 16–23 h and a tmax of approximately 1 h. The MTDs for the oral solution of SAGE-217 in the SAD and MAD studies were determined to be 55 and 30 mg daily, respectively. In both studies, SAGE-217 was generally well tolerated, and no serious adverse events (SAEs) were reported. Most AEs were mild, dose-dependent, transient, occurred around the tmax, and related to drug pharmacology. Conclusions SAGE-217 was generally well tolerated, and its PK profile was well characterized. Based on this profile, SAGE-217 has been advanced into multiple phase II clinical programs and pivotal studies of major depressive disorder and postpartum depression.

Abstract
Objective The authors systematically reviewed evidence on pharmacotherapy for perinatal mental health disorders. Methods The authors searched for studies of pregnant, postpartum, or reproductive-age women with mental health disorders treated with pharmacotherapy in MEDLINE, EMBASE, PsycINFO, the Cochrane Library, and trial registries from database inception through June 5, 2020 and surveilled literature through March 2, 2021. Outcomes included symptoms; functional capacity; quality of life; suicidal events; death; and maternal, fetal, infant, or child adverse events. Results 164 studies were included. Regarding benefits, brexanolone for third-trimester or postpartum depression onset may be associated with improved depressive symptoms at 30 days when compared with placebo. Sertraline for postpartum depression may be associated with improved response, remission, and depressive symptoms when compared with placebo. Discontinuing mood stabilizers during pregnancy may be associated with increased recurrence of mood episodes for bipolar disorder. Regarding adverse events, most studies were observational and unable to fully account for confounding. Evidence on congenital and cardiac anomalies for treatment compared with no treatment was inconclusive. Brexanolone for depression onset in the third trimester or the postpartum period may be associated with risk of sedation or somnolence, leading to dose interruption or reduction when compared with placebo. Conclusions Evidence from few studies supports the use of pharmacotherapy for perinatal mental health disorders. Although many studies report on adverse events, they could not rule out underlying disease severity as the cause of the association between exposures and adverse events. Patients and clinicians need to make informed, collaborative decisions on treatment choices.

Abstract
Traumatic brain injury (TBI) causes cellular and molecular alterations that contribute to neuropsychiatric disease and epilepsy. GABAergic dysfunction figures prominently in the pathophysiology of TBI, yet the effects of TBI on tonic inhibition in hippocampus remain uncertain. We used a mouse model of severe TBI [controlled cortical impact (CCI)] to investigate GABAergic signaling in dentate gyrus granule cells (DGGCs). Basal tonic GABA currents were not affected by CCI. However, tonic currents induced by the δ subunit-selective GABAA receptor agonist 4,5,6,7-tetrahydroisoxazolo[5,4-c]pyridin-3-ol (THIP; 10 μm) were reduced by 44% in DGGCs ipsilateral to CCI (CCI-ipsi), but not in contralateral DGGCs. Reduced THIP currents were apparent one week after injury and persisted up to 15 weeks. The frequency of spontaneous IPSCs (sIPSCs) was reduced in CCI-ipsi cells, but the amplitude and kinetics of sIPSCs were unaffected. Immunohistochemical analysis showed reduced expression of GABAA receptor δ subunits and GABAB receptor B2 subunits after CCI, by 43% and 40%, respectively. Activation of postsynaptic GABAB receptors caused a twofold increase in tonic currents, and this effect was markedly attenuated in CCI-ipsi cells (92% reduction). GABAB receptor-activated K+ currents in DGGCs were also significantly reduced in CCI-ipsi cells, confirming a functional deficit of GABAB receptors after CCI. Results indicate broad disruption of GABAergic signaling in DGGCs after CCI, with deficits in both phasic and tonic inhibition and GABAB receptor function. These changes are predicted to disrupt operation of hippocampal networks and contribute to sequelae of severe TBI, including epilepsy.

Abstract
The efficacy of standard antidepressants is limited for many patients with mood disorders such as major depressive disorder (MDD) and bipolar depression, underscoring the urgent need to develop novel therapeutics. Both clinical and preclinical studies have implicated glutamatergic system dysfunction in the pathophysiology of mood disorders. In particular, rapid reductions in depressive symptoms have been observed in response to subanesthetic doses of the glutamatergic modulator racemic (R,S)-ketamine in individuals with mood disorders. These results have prompted investigation into other glutamatergic modulators for depression, both as monotherapy and adjunctively. Several glutamate receptor-modulating agents have been tested in proof-of-concept studies for mood disorders. This manuscript gives a brief overview of the glutamate system and its relevance to rapid antidepressant response and discusses the existing clinical evidence for glutamate receptor-modulating agents, including (1) broad glutamatergic modulators ((R,S)-ketamine, esketamine, (R)-ketamine, (2R,6R)-hydroxynorketamine [HNK], dextromethorphan, Nuedexta [a combination of dextromethorphan and quinidine], deudextromethorphan [AVP-786], axsome [AXS-05], dextromethadone [REL-1017], nitrous oxide, AZD6765, CLE100, AGN-241751); (2) glycine site modulators (D-cycloserine [DCS], NRX-101, rapastinel [GLYX-13], apimostinel [NRX-1074], sarcosine, 4-chlorokynurenine [4-Cl-KYN/AV-101]); (3) subunit (NR2B)-specific N-methyl-D-aspartate (NMDA) receptor antagonists (eliprodil [EVT-101], traxoprodil [CP-101,606], rislenemdaz [MK-0657/CERC-301]); (4) metabotropic glutamate receptor (mGluR) modulators (basimglurant, AZD2066, RG1578, TS-161); and (5) mammalian target of rapamycin complex 1 (mTORC1) activators (NV-5138). Many of these agents are still in the preliminary stages of development. Furthermore, to date, most have demonstrated relatively modest effects compared with (R,S)-ketamine and esketamine, though some have shown more favorable characteristics. Of these novel agents, the most promising, and the ones for which the most evidence exists, appear to be those targeting ionotropic glutamate receptors.

Abstract
Remarkable advances in understanding the role of RNA in health and disease have expanded considerably in the last decade. RNA is becoming an increasingly important target for therapeutic intervention; therefore, it is critical to develop strategies for therapeutic modulation of RNA function. Oligonucleotides, including antisense oligonucleotide (ASO), small interfering RNA (siRNA), microRNA mimic (miRNA), and anti-microRNA (antagomir) are perhaps the most direct therapeutic strategies for addressing RNA. Among other mechanisms, most oligonucleotide designs involve the formation of a hybrid with RNA that promotes its degradation by activation of endogenous enzymes such as RNase-H (e.g., ASO) or the RISC complex (e.g. RNA interference - RNAi for siRNA and miRNA). However, the use of oligonucleotides for the treatment of brain disorders is seriously compromised by two main limitations: i) how to deliver oligonucleotides to the brain compartment, avoiding the action of peripheral RNAses? and once there, ii) how to target specific neuronal populations? We review the main molecular pathways in major depressive disorder (MDD) and Parkinson's disease (PD), and discuss the challenges associated with the development of novel oligonucleotide therapeutics. We pay special attention to the use of conjugated ligand-oligonucleotide approach in which the oligonucleotide sequence is covalently bound to monoamine transporter inhibitors (e.g. sertraline, reboxetine, indatraline). This strategy allows their selective accumulation in the monoamine neurons of mice and monkeys after their intranasal or intracerebroventricular administration, evoking preclinical changes predictive of a clinical therapeutic action after knocking-down disease-related genes. In addition, recent advances in oligonucleotide therapeutic clinical trials are also reviewed.

Abstract
The COVID-19 pandemic has caused unprecedented rates of unemployment in the United States. Pregnant workers may be especially affected as they are over-represented in low-wage service and hospitality industries impacted by the pandemic. We surveyed an online convenience sample of currently working pregnant people living in the U.S. (n = 1,417) to determine whether COVID-19-related changes to how long individuals planned to work during their pregnancy, and uncertainty about these changes, were associated with prenatal depression. As hypothesized, both COVID-19-related work-plan changes (OR = 1.81, 95% CI 1.36-2.42, p < 0.001) and uncertainty about the precise nature of these changes (OR = 2.62, 95% CI 1.14-6.0, p = 0.022) were associated with significantly higher odds of a clinically-significant depression score. These effects appeared to be even greater among individuals who continued working outside the home during the pandemic. Since the U.S. is one of the few countries in the world that does not guarantee paid parental leave, pregnant people may be forced to choose between keeping their jobs and risking infection during the COVID-19 pandemic. Our results demonstrate a need for immediate suspension of the eligibility requirements for the Family and Medical Leave Act and/or universal access to both paid family leave and prenatal depression screening. This would help to alleviate these concerns and provide pregnant people with more options while preserving their employment status and financial security.

Abstract
Endocrine disturbances play predominant roles in recently discovered, clinically relevant abnormalities in depression. These affect multiple sites in the prefrontal cortex, amygdala, hippocampus, nucleus accumbens, and habenula. Deficits consist of changes in volume, neuroplasticity, neural connectivity, synapse composition, and neurogenesis. Depression is associated with endocrine-related, premature systemic disease, that results in a loss of approximately 7 years of life. CRH, glucocorticoids, somatostatin, gonadal steroids, and thyroid hormones all contribute to the deficits that largely define the pathophysiologic presentation of depression. The World Health Organization ranks depression as the second greatest cause of disability worldwide. The response rate to current antidepressants is below 60%. It is important that new knowledge about the endocrine-mediated pathophysiology of depression be communicated to provide targets for new agents.

Abstract
INTRODUCTION Postpartum depression (PPD) is a serious and common complication of childbirth that can have deleterious effects not only on the mother but on the cognitive and behavioral development of exposed children. Brexanolone is a novel, soluble synthetic formulation of the natural hormone allopregnanolone and acts as a positive allosteric modulator of the gamma-aminobutyric acid A receptor (GABAA). Allopregnanolone levels dramatically decrease during the postpartum time-period and some studies indicate lower serum levels of allopregnanolone during pregnancy in women that go on to develop PPD.Areas covered: The author provides an overview of brexanolone as a treatment option for PPD including coverage of its pharmacokinetics, efficacy, safety, and tolerability. Furthermore, the author gives her expert perspectives on its use and its standing in the treatment armamentarium moving forward.Expert opinion: Brexanolone represents a breakthrough for psychiatry due to its novel mechanism of action, its rapid onset of action, and its sustained effects without continued administration. It is appropriate for use in women with moderate to severe PPD. Experience with the medication and further research is needed to clarify whether the current recommended dosing regimen is required for efficacy.

Abstract
Major depressive disorder (MDD) is a potentially life-threatening mental disorder imposing severe social and economic burden worldwide. Despite the existence of effective antidepressant treatment strategies the exact pathophysiology of the disease is still unknown. Large number of animal models of MDD have been developed over the years, but all of them suffer from significant shortcomings. Despite their limitations these models have been extensively used in academic research and drug development. The aim of this review is to highlight the benefits of animal models of MDD. We focus here on recent experimental data where animal models were used to examine current theories of this complex disease. We argue, that despite their evident imperfections, these models provide invaluable help to understand cellular and molecular mechanisms contributing to the development of MDD. Furthermore, animal models are utilized in research to find clinically useful biomarkers. We discuss recent neuroimaging and microRNA studies since these investigations yielded promising candidates for biomarkers. Finally, we briefly summarize recent progresses in drug development, i.e. the FDA approval of two novel antidepressant drugs: S-ketamine and brexanolone (allopregnanolone). Deeper understanding of the exact molecular and cellular mechanisms of action responsible for the antidepressant efficacy of these rapid acting drugs could aid us to design further compounds with similar effectiveness, but less side effects. Animal studies are likely to provide valuable help in this endeavor.

Abstract
Background: Brexanolone (BRX) injection was approved by the United States Food and Drug Administration in 2019 for the treatment of adults with postpartum depression (PPD) based on two Phase 3 clinical trials. Materials and Methods: Data from the three trials were combined. PPD-specific 17-item Hamilton Rating Scale for Depression (HAMD-17) group-level minimal important difference (MID) and patient-level meaningful change (meaningful change threshold [MCT]) were estimated and applied to differences in BRX versus placebo (PBO) at hour 60 (primary endpoint) and day 30 (end of trial follow-up). Likelihood of HAMD-17 response and remission and Clinical Global Impression of Improvement (CGI-I) response for BRX versus PBO were assessed at hour 60 and as sustained through day 30 using relative risk. Associated number needed to treat (NNT) and number needed to harm (NNH) values were also estimated. Results: Two-hundred nine patients were included. The average HAMD-17 MID estimate was -2.1; the least-squared mean difference between BRX and PBO exceeded this at hour 60 and day 30. Minimal, moderate, and large MCTs were estimated to be -9, -15, and -20 points, respectively. Significantly more BRX-treated than PBO-treated patients achieved minimal, moderate, and large change (all ps < 0.05) at hour 60 and large meaningful response at day 30 (p < 0.05). BRX-treated patients were more likely to sustain HAMD-17 remission and CGI-I response through day 30 versus PBO. NNTs ranged from 4 to 8, with NNH of 97. Conclusions: BRX provided meaningful changes relative to PBO, rapid (hour 60), and sustained improvements (day 30) in PPD symptoms, low NNT, and large NNH. These results may help inform treatment decision-making. Clinicaltrials.gov registration numbers: NCT02614547, NCT02942004, and NCT02942017.

Abstract
Stress and trauma exposure disturbs stress regulation systems and thus increases the vulnerability for stress-related disorders which are characterized by negative affect, including major depressive disorder, anxiety disorders and posttraumatic stress disorder. Similarly, stress and trauma exposure results in increased vulnerability to problematic alcohol use and alcohol use disorder, especially among women, who are more likely to drink to cope with negative affect than their male counterparts. Given these associations, the relationship between stress-related disorders and alcohol use is generally stronger among women leading to complex comorbidities across these disorders and alcohol misuse. This review highlights the therapeutic potential for progestogen- and androgen-derived neurosteroids, which affect both stress- and alcohol-related disorders, to target the overlapping symptoms related to negative affect. This article is part of the special issue on 'Vulnerabilities to Substance Abuse.'

Abstract
Neuroactive steroids are an ascendant class of treatment for neuropsychiatric illness. Effects on ligand-gated neurotransmitter receptors appear to be a major mechanism of action. Here we describe a neuroactive steroid with a unique constellation of receptor actions. MQ-221 is a sulfated, 3β-hydroxy neurosteroid analogue that inhibits NMDAR function but also potentiates GABAAR function, thereby exhibiting unusual but potentially clinically desirable effects. Although the compound also exhibited features of other sulfated steroids, namely activation-dependent inhibition of GABAAR function, net potentiation dominated under physiological conditions. Potentiation of GABAAR function was distinct from the mechanism governing potentiation by anesthetic neurosteroids. Inhibition of NMDAR function showed weaker channel activation dependence than pregnanolone sulfate (3α5βPS). MQ-221 was unique among four stereoisomers explored in the pattern of effects at GABAA and NMDARs. Taken together, MQ-221 may represent a new class of compound with unique psychoactive effects and beneficial prospects for treating neuropsychiatric disorders.

Abstract
Women worldwide are two to three times more likely to suffer from depression in their lifetime than are men. Female risk for depressive symptoms is particularly high during the reproductive years between menarche and menopause. The term “Reproductive Mood Disorders” refers to depressive disorders triggered by hormonal fluctuations during reproductive transitions including the perimenarchal phase, the pre-menstrual phase, pregnancy, the peripartum period and the perimenopausal transition. Here we focus on reproductive mood disorders manifesting in adult life. We propose a research agenda that draws together several reproductive mood disorders and investigates which genetic, endocrinological, neural, and psychosocial factors can explain depressive symptoms during phases of hormonal transitions in women. Based on current research it is assumed that some women experience an increased sensitivity to not only fluctuations in reproductive steroids (estrogen and progesterone), but also stress-related steroids. We integrate both dynamics into the concept of “steroid hormone sensitivity,” expanding on the concept of “reproductive hormone sensitivity.” We suggest that a differential response of the stress steroid system including corticosteroids, neurosteroids, like allopregnanolone and the GABA-A Receptor complex, as well as a differential (epi)genetic risk in serotonergic and GABAergic signaling, are moderators or mediators between changes in the reproductive steroid system and the physiological, affective, and cognitive outcomes manifesting in reproductive mood disorders. We point to the lack of research on the role of psychosocial factors in increasing a woman's stress level and at some point also the sensitivity of her stress steroid system within the etiology of Reproductive Mood Disorders. Drawing together the evidence on various reproductive mood disorders we seek to present a basis for the development of more effective pharmacological, social, and psychological treatment interventions and prevention strategies for women susceptible to these disorders. This could pave the way for new research as well as medical and psychological teaching and practice- such as a new type of Practice for Gynecological Psychoneuroendocrinology- with the aim of working on and ultimately offering more integrative forms of support not yet available to women suffering from depression during hormonal transitions. In medical history women have been left alone with this integrative challenge.

Abstract
Perinatal care, including the management of mental health issues, often falls under the auspices of primary care providers. Postpartum depression (PPD) is a common problem that affects up to 15% of women. Most women at risk can be identified before delivery based on psychiatric history, symptoms during pregnancy, and recent psychosocial stressors. Fortunately, there have been a variety of treatment studies using antidepressants, nonpharmacologic interactions, and most recently, allopregnanolone (Brexanolone) infusion that have shown benefits. The most commonly used screening scale, Edinburgh Postnatal Depression Scale, a 10-item self-rated scale, has been translated into a variety of languages.

Abstract
Postpartum depression (PPD) is one of the three major categories on the spectrum of postpartum psychiatric syndromes. Postpartum psychiatric syndromes are classified as either postpartum blues, postpartum depression, or postpartum psychosis. Postpartum depression is important to recognize clinically because of the effect it can have on the mother-child bond. The neurosteroid allopregnanolone, a progesterone derivative, is important for its role in positively modulating GABAA receptors. GABA-mediated signaling has been previously implicated in major depressive disorder. Allopregnanolone-mediated signaling has been identified as an important therapeutic target. Treatment with an allopregnanolone-analog, brexanolone, has been shown to improve depression scores in trials for the treatment of PPD. Brexanolone is a positive allosteric modulator of GABAA and is the first drug approved by the FDA to treat postpartum depression. Brexanolone enhances the inhibitory effects of GABAA, restores dysfunctional GABAA transmembrane channels, and mimics a naturally produced progesterone metabolite that fluctuates during pregnancy and postpartum. One open-label study and two phase two studies have some significant reduction in HAM-D scores after treatment and that the effect was still there 30 days post-treatment. Per the data reported, intravenous infusion of brexanolone could be efficacious and safe for the treatment of women suffering from postpartum depression.

Abstract
At least one in seven pregnant or recently postpartum women will experience a mental illness such as an anxiety disorder, depressive disorder, or substance use disorder. These mental illnesses have detrimental effects on the health of the mother, child, and family, but little is known about the hypothalamic and other neural correlates of maternal mental health concerns. The transition to parenthood alone is a time of remarkable neural plasticity, so it is perhaps not surprising that current research is showing that maternal mental illness has unique neural profiles. Furthermore, the neural systems affected by peripartum mental illness overlap and interact with the systems involved in maternal caregiving behaviors, and mother-infant interactions are, therefore, highly susceptible to disruption. This review discusses what we know about the unique neural changes occurring during peripartum mental illness and the role of the hypothalamus in these illnesses. With an improved understanding of the neural correlates of maternal mental health and disease, we will be better equipped to predict risk, develop effective treatments, and ultimately prevent suffering for millions of parents during this critical time in life.

Abstract
Mood disorders represent a pressing public health issue and significant source of disability throughout the world. The classical monoamine hypothesis, while useful in developing improved understanding and clinical treatments, has not fully captured the complex nature underlying mood disorders. Despite these shortcomings, the monoamine hypothesis continues to dominate the conceptual framework when approaching mood disorders. However, recent advances in basic and clinical research have led to a greater appreciation for the role that amino acid neurotransmitters play in the pathophysiology of mood disorders and as potential targets for novel therapies. In this article we review progress of compounds that focus on these systems. We cover both glutamate-targeting drugs such as: esketamine, AVP-786, REL-1017, AXS-05, rapastinel (GLYX-13), AV-101, NRX-101; as well as GABA-targeting drugs such as: brexanolone (SAGE-547), ganaxolone, zuranolone (SAGE-217), and PRAX-114. We focus the review on phase-II and phase-III clinical trials and evaluate the extant data and progress of these compounds.

Abstract
Clinical studies have demonstrated that allopregnanolone (3α5α-tetrahydroprogesterone, ALLO) has antidepressant-like effects on patients with depression. Previous studies have shown alteration of the astroglial glutamate transporter-1 (GLT-1) and glutamine synthetase (GS) in depression, and ALLO is known to modulate glutamate release. The present study aimed to investigate whether astroglial GLT-1 and GS are indeed involved in the antidepressant-like effects of ALLO in learned helplessness (LH) rats, a validated animal model of depression. The results of this study showed that bilateral microinjection of ALLO into the lateral ventricles could normalize the levels of GLT-1 and GS in the nucleus accumbens (NAc) and of GS in the hippocampal CA1 region of LH rats. These results suggest a certain connection between the antidepressant-like effects of ALLO and the astroglial GLT-1/GS system of the NAc in LH rats.

Abstract
INTRODUCTION Allopregnanolone is an endogenous neurosteroid with the potential to be a novel regenerative therapeutic for Alzheimer's disease (AD). Foundations of mechanistic understanding and well-established preclinical safety efficacy make it a viable candidate. METHODS A randomized, double-blinded, placebo-controlled, single and multiple ascending dose trial was conducted. Intravenous allopregnanolone or placebo was administered once-per-week for 12 weeks with a 1-month follow-up. Participants with early AD (mild cognitive impairment due to AD or mild AD), a Mini-Mental State Examination score of 20-26 inclusive, and age ≥55 years were randomized (6:2 to three allopregnanolone dosing cohorts or one placebo cohort). Primary endpoint was safety and tolerability. Secondary endpoints included pharmacokinetic (PK) parameters and maximally tolerated dose (MTD). Exploratory endpoints included cognitive and imaging biomarkers. RESULTS A total of 24 participants completed the trial. Allopregnanolone was safe and well tolerated in all study participants. No differences were observed between treatment arms in the occurrence and severity of adverse events (AE). Most common AE were mild to moderate in severity and included rash (n = 4 [22%]) and fatigue (n = 3 [17%]). A single non-serious AE, dizziness, was attributable to treatment. There was one serious AE not related to treatment. Pharmacokinetics indicated a predictable linear dose-response in plasma concentration of allopregnanolone after intravenous administration over 30 minutes. The maximum plasma concentrations for the 2 mg, 4 mg, 6 mg, and 10 mg dosages were 14.53 ng/mL (+/-7.31), 42.05 ng/mL (+/-14.55), 60.07 ng/mL (+/-12.8), and 137.48 ng/mL (+/-38.69), respectively. The MTD was established based on evidence of allopregnanolone-induced mild sedation at the highest doses; a sex difference in the threshold for sedation was observed (males 10 mg; females 14 mg). No adverse outcomes on cognition or magnetic resonance imaging-based imaging outcomes were evident. CONCLUSIONS Allopregnanolone was well tolerated and safe across all doses in persons with early AD. Safety, MTD, and PK profiles support advancement of allopregnanolone as a regenerative therapeutic for AD to a phase 2 efficacy trial. TRIAL REGISTRATION ClinicalTrials.gov-NCT02221622.

Abstract
OBJECTIVES To review the pharmacology, efficacy, and safety of Brexanolone and define its role in the treatment of postpartum depression. DATE SOURCES A MEDLINE/PubMed search was conducted (1980-May 2020) using the following keywords: postpartum depression, antidepressants, pharmacologic therapy, drug therapy, and brexanolone to identify relevant articles. STUDY SELECTION/DATA EXTRACTION Literature search was limited to human studies published in the English language. Phase I, II, and III studies evaluating the pharmacology, efficacy, safety of brexanolone for postpartum depression were included. Bibliographies of relevant articles evaluating postpartum depression and treatment were reviewed for additional citations and background information. DATA SYNTHESIS Brexanolone is a soluble, proprietary, injectable formulation of allopregnanolone, a neuroactive steroid that modulates neuronal excitability. Allopregnanolone levels increase during pregnancy and decrease substantially after birth. These fluctuations have profound effects on anxiety and depression. Three clinical trials established the efficacy and safety of brexanolone in the treatment of postpartum depression. In all 3 trials, brexanolone had an acceptable safety profile and was well tolerated. The most common adverse effects were loss of consciousness, sedation, dry mouth, headache, dizziness, and flushing. Due to sudden loss of consciousness and excessive sedation, continuous pulse oximetry is recommended. CONCLUSION Brexanolone has a novel mechanism of action and appears to be safe and effective for the treatment of moderate to severe postpartum depression. At present, high cost, serious adverse effects, and restricted access may limit its use in clinical practice.

Abstract
The hypothesis of monoaminergic deficiency has long dominated the conceptual framework for the development of new antidepressant strategies, but the limits of conventional antidepressant treatments targeting monoaminergic signaling have motivated the search for new antidepressant pathways. The success of ketamine in the management of depressive disorders has provoked a renewed interest in hallucinogenic substances such as psilocybin targeting the serotonergic signaling 5HT2A and neurosteroid allosteric modulator of γ-aminobutyric acid (GABAA) receptors such as brexanolone. Unlike conventional treatments, these modulators of glutamatergic, serotonergic and GABAergic systems exert a rapid antidepressant effect ranging from 24hours to a week. Apart from their clinical interest and the fantasized search for a "miracle" molecule that jointly meets the expectations of patients and clinicians, these new targets could lead to the identification of potential new biomarkers for the development of rapid-acting antidepressants and redefine therapeutic strategies in mood disorders.
