STUDY SYNOPSIS 
Protocol number:  
1042-PPD-2003 
Drug:  
Ganaxolone IV, oral suspension, and oral capsule formulations 
Title of the study:  A Phase 2, Double-blind, Placebo-controlled, Multicenter Study to Evaluate Safety, Tolerability 
and Efficacy of IV and Oral Administration of Ganaxolone in Women with Postpartum Depression 
Design:  
This is a Phase 2, multicenter study in women with postpartum depression (PPD) consisting of 2 parts:  An Open 
Label Part with multiple ascending doses focused on safety and tolerability in 5 groups that differ by total daily 
dosing and formulation of study drug; and a Double-blind Placebo-controlled (DBPC) part focused on safety, 
tolerability and efficacy in one group.  The DBPC Part will begin after the Open Label Part dosing is completed.  The 
dosing, treatment duration and timing of evaluations for the double-blind portion of the study will be decided based 
on the results of the Open Label Part and recommendations of the Data Review Committee (DRC).  The DRC is 
comprised of Marinus’ Chief Medical Officer and 2 external physician experts.   
Figure 1-A and Figure 1-B depict the design for each subject group in the Open Label and DBPC Parts, respectively. 
Number of subjects and dose regimen for each treatment arm:  
For the Open Label Part, approximately 176 women aged 18 to 48 years with PPD will be screened to enroll 
approximately 88 subjects.   
The first group (called open-label 3 times daily [OL TID]) of approximately 8 subjects will receive oral ganaxolone 
(capsules) titrated to a daily dose of 900 mg/day over 10 days, followed by a taper over 4 days.   
The second group (called open-label administered at bedtime [OL QHS]) of approximately 20 subjects will receive 
oral ganaxolone (capsules) at bedtime (QHS), titrated to a dose of 675 mg QHS over 4 days and maintained until 
Day 10, followed by a taper over 4 days.  
The third group (called OL QHS 4-week) of approximately 20 subjects will be administered oral ganaxolone 
(capsules) at a dose of 675 mg QHS for 28 days, followed by a taper over 4 days.  
The fourth group (called OL 1,125 mg group) of approximately 20 subjects will receive on the first 2 days, oral 
ganaxolone capsules at a dose of 675 mg at approximately 7 pm (with dinner) and 675 mg at 10 pm (with a fatty 
snack), followed by 26 days of ganaxolone 1,125 mg at dinner time, and a taper over 4 days.  Approximately 6 
subjects will participate in pharmacokinetics (PK) collection that requires an overnight stay on Day 1. 
The fifth group (called OL Bolus-oral) of approximately 20 subjects will receive ganaxolone starting with a single 
intravenous (IV) 12 mg bolus over 2 minutes at approximately 4 pm of Day 1, followed by ganaxolone oral 
suspension 750 mg at 6pm (with a fatty meal), and 750 mg at 10pm (with a fatty snack).  On Day 2, subjects will 
receive ganaxolone oral suspension 750 mg at dinner time and 750 mg at bedtime, followed by 26 days of 
ganaxolone oral suspension 1,000 mg at dinner time.  Treatment will then be tapered over 4 days.  Approximately 6 
subjects will participate in PK collection that requires an overnight stay on Day 1.

Figure 1-A:  Design of Open-Label Part 
 
For DBPC part, approximately 100 women with PPD aged 18 to 48 years will be screened to randomize 50 women in 
a 1:1 ratio to receive ganaxolone or matching placebo for 14 days.  The dosing, treatment duration and timing of 
evaluations for the double-blind portion of the study will be decided based on the results of the Open Label Part and 
recommendations of the DRC.  The total daily dose will not exceed 1,600 mg.  Randomization will be stratified by 
the use of concomitant antidepressants so that the number of subjects who are treated with antidepressants and who 
are not treated with antidepressants will be similar in each treatment group.

The investigator has the flexibility to adjust the dose and/or timing of the dose if the subject experiences sedation, 
dizziness or other untoward effects in each dosing group, by reducing the dose first to a lower level and possibly 
increasing it later if tolerance develops to the untoward effects (see Section 6.2.7).

Study period (planned): 
September 2017 to June 2019 
Clinical phase:  Phase 2 
Objectives:  
Open-Label Part:  Safety, dosing, efficacy and pharmacokinetics 
1. To assess the safety and tolerability of ganaxolone in women with PPD as determined by adverse events (AEs), 
changes from baseline in laboratory measures, vital signs, Columbia Suicide Severity Rating Scale (CSSRS), 
electrocardiogram (ECG), Stanford Sleepiness Scale (SSS), and physical examination.  
2. To develop an optimal dosing regimen for the double-blind part.  Adverse events and other safety data, including 
sedation and dosing changes will be adjudicated by the DRC before proceeding to the double-blind part of the 
study.   
3. To assess the efficacy of ganaxolone using the Hamilton Depression Rating Scale 17-item version (HAMD17), 
Edinburgh Postnatal Depression Scale (EPDS), Spielberger State-Trait Anxiety Inventory 6-item version 
(STAI6) and Clinical Global Impression-Severity and Improvement (CGI-S and CGI-I) scales.  
4. To collect samples of blood for PK analysis after administration of oral and IV ganaxolone to use in 
population-PK analyses, the results of which will be reported separately by the Sponsor. 
Double-Blind placebo controlled (DBPC) Part:  Safety, efficacy, and pharmacokinetics 
Safety objective:  To assess the safety and tolerability of ganaxolone vs placebo in women with PPD as determined 
by AEs and changes from baseline in laboratory measures, vital signs, CSSRS, ECG, SSS, and physical examination.   
Efficacy objective:  To assess the efficacy of ganaxolone vs placebo using the HAMD17, EPDS, STAI6 and CGI-S 
and CGI-I scales.  
The primary efficacy variable in this study is change from baseline in the HAMD17 total score on Day 10 of the 
DBPC part between ganaxolone and matching placebo.   
Pharmacokinetic objective:  To collect samples of blood for PK analyses after administration of oral ganaxolone to 
use in population-PK analyses, the results of which will be reported separately by the Sponsor. 
Rationale:  Rapidly declining plasma levels of allopregnanolone and other neurosteroids after childbirth are thought 
to be linked to triggering depression in women who are vulnerable to develop this condition.  Ganaxolone, a synthetic 
analog of allopregnanolone, may provide benefit to these women.  This study is intended to test the safety and 
efficacy of ganaxolone in the treatment of PPD. 
Investigational product, dose, and mode of administration:  Ganaxolone IV, oral suspension, and oral capsule 
(225 mg/capsule) formulations and matching placebo will be used.   
Inclusion Criteria:  
1. An understanding of and ability, and willingness to fully comply with study procedures and restrictions.  
2. Ability to voluntarily provide written, signed, and dated informed consent as applicable to participate in the 
study. 
3. Female aged 18 to 48 years inclusive, at the Screening Visit 
4. Experiencing a major depressive episode, which started between the start of the third trimester and 4 weeks 
following delivery.  The major depressive episode must be diagnosed according to Mini International 
Neuropsychiatric Interview (MINI) 7.0 interview  
5. Given birth in the last 12 months 
6. HAMD17 score of ≥ 20 at screening rated by a certified site rater.

childcare provider and support person at home (including during the night) while the subject is participating in 
the trial 
Exclusion Criteria 
1. Current or past history of any psychotic illness, including major depressive episode with psychotic features 
2. Any psychiatric condition that, in the investigator’s judgment, is considered clinically significant and could 
affect subject safety or study outcome including eating disorder, panic disorder, obsessive-compulsive disorder, 
or post-traumatic stress disorder 
3. History of suicide attempt within the past 3 years 
4. Active suicidal ideation (e.g., answering “yes” to questions 4 or 5 in the CSSRS suicidal ideation section) 
5. History of severe bipolar I disorder (e.g. hospitalization due to the illness, lifetime history of psychosis or suicide 
attempt).  
6. Uncontrolled seizure disorder  
7. Current or history within the past 3 years of alcohol or any substance use disorder, with the exception of tobacco 
or caffeine 
8. Positive drug screen for any illicit substances or prescription drugs at screening or randomization.  If the drug 
screen is positive for a prescription drug that has the potential to be abused (e.g., amphetamine, benzodiazepine), 
legitimate use of the drug must be verified by the subject’s providing the current pill bottle, prescription for the 
drug, or a note from the prescribing physician.  Cannabis use is prohibited, and subjects with positive drug screen 
for cannabis are excluded.  However, occasional users of cannabis may be re-tested after 5 days if the subject is 
willing to refrain from consuming cannabis-based products during the trial.  If the re-test sample is negative at 
screening, the subject can be considered eligible.  If the re-test sample is positive for cannabis, the investigator 
may ask for determination of blood levels of ∆9-tetrahydrocannabinol (THC), and its metabolites 11-hydroxy-
THC and 9-carboxy-THC.  If THC is not detectable, the subject is eligible for the trial.   
9. Current or relevant history of any medical disorder that may require treatment or make the subject unlikely to be 
able to complete the study, or any condition that presents undue risk from the investigational product or 
procedure point of view 
10. Any clinically significant abnormality identified on physical examination, ECG, or laboratory tests that in the 
judgment of the investigator would compromise the subject’s safety or successful participation in the clinical 
study

19. Subject is pregnant 
20. Subject is using prohibited medications as specified in Section 5.3.2 
Maximum duration of subject involvement in the study:  Approximately 7 weeks for the OL TID and OL QHS 
groups and the DBPC part.  The duration for the OL QHS 4-week group is approximately 18 weeks and the duration 
for the OL 1,125 mg and OL Bolus-oral groups is approximately 12 weeks.  
Key variables: 
Safety:  Adverse events, laboratory measures, vital signs, CSSRS, ECG, SSS, and physical examination. 
Efficacy:  HAMD17, EPDS, STAI6, CGI-I and CGI-S scales. 
Pharmacokinetics:  For the OL TID and OL QHS groups, a total of 5 samples of blood will be collected to 
determine ganaxolone plasma concentrations during the study.  Samples will be collected on 3 occasions during 
treatment with ganaxolone to determine trough concentrations in plasma.  An additional 2 samples of blood will be 
collected at follow up visits, after ganaxolone treatment has been completed, to monitor the disappearance of 
ganaxolone following cessation of treatment.  For the OL QHS 4-week, OL 1,125 mg, and OL Bolus-oral groups, 
6 samples of blood will be collected to determine ganaxolone plasma concentrations during the study.  Samples will 
be collected on 4 occasions during treatment in the OL QHS 4 weeks group and on 5 occasions during treatment in 
the OL 1,125 mg and OL Bolus-oral groups to determine ganaxolone trough concentrations in plasma.  Two 
additional samples of blood will be collected in the first 2 follow up visits in the OL QHS 4 weeks group and 
1 additional sample will be collected in the OL 1,125 mg, and OL Bolus-oral groups at the first follow up visit after 
ganaxolone treatment has been completed, to monitor the disappearance of ganaxolone following cessation of 
treatment.  
Statistical Methods:  Data will be presented by study part (OL, DBPC), dosing or treatment group within study parts 
and if applicable, study visit.  Continuous variables will be summarized as numbers of observations, means, measures 
of variance (e.g., standard deviation), and percentiles (e.g., median, minimum, maximum).  Categorical variables will 
be summarized as numbers of observations and percentages. 
Analysis Populations:  The Screened Set will consist of all subjects who have signed an informed consent.  The 
Randomized Set will consist of subjects randomized in the DBPC part of the trial.  The Safety Set will consist of all 
subjects who received investigational product (IP).  The modified Intent to Treat (mITT) Set will consist of all 
subjects in the DBPC part of the trial who received IP, and who have at least 1 post-baseline HAMD17 assessment.  
The Per-Protocol Set will consist of all subjects in the mITT set who do not have major protocol deviations that may 
affect key efficacy endpoints. 
Efficacy Analysis:  Efficacy parameters will be summarized for both the OL and DBPC parts, but will be analyzed 
only for the DBPC part.  The primary time point of interest for all efficacy parameters will be Day 10 for the DBPC 
part and the visit at end of treatment (before initiation of taper) for the OL part.  The primary efficacy endpoint will 
be change from baseline in HAMD17 total score at Day 10 for the DBPC part and at the visit at end of treatment for 
the OL part.  The primary efficacy analysis will be done using the mITT set (DBPC group only), and the analytical 
method will be mixed model repeated measures (MMRM) with baseline HAMD17 total score as a covariate.  
Significance will be tested at a two-sided 0.05 level. 
Secondary efficacy endpoints will be change from baseline in HAMD17 total score other than at the primary endpoint 
time point, HAMD17 response defined as at least a 50% reduction from baseline in total score, HAMD17 remission 
defined as total score < = 7, change from baseline in EPDS total score, change from baseline in STAI6, and 
CGI-Improvement.

1 BACKGROUND INFORMATION 
1.1 
Postpartum Depression (PPD) 
Postpartum depression (PPD) is a mood disorder that occurs in about 7% of women following 
the birth of a child.1  Common symptoms include feelings of extreme sadness, hopelessness, 
suicidal ideation, anxiety, and fatigue, which 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.2  
Rapid changes in the levels of endogenous neurosteroids during pregnancy are thought to be 
related to the development of PPD.  Plasma levels of allopregnanolone, which is a metabolite of 
progesterone and an endogenous gamma-aminobutyric acid (GABA) receptor modulator, are 
known to increase throughout pregnancy and then precipitously drop after delivery.3, 4  It is 
thought that these rapid hormonal changes are linked to triggering depression in women who are 
vulnerable to develop this condition.  Serotonin selective reuptake inhibitors (SSRIs) are known 
to increase allopregnanolone, and it has been suggested that this mechanism could explain why 
SSRIs have shown therapeutic effect in the treatment of PPD.5  There have been a limited 
number of placebo-controlled randomized clinical trials testing the efficacy of SSRIs, or any 
other medication, in the treatment of PPD.6,5 
Data were recently published that demonstrated that a continuous infusion of allopregnanolone 
rapidly alleviates symptoms of depression in women with PPD.7  In this open-label study, 
4 women with severe PPD received a 60-hour infusion of allopregnanolone.  The mean 
Hamilton Depression Rating Scale for Depression (HAMD) before the infusion was 26.5, 
indicating that the women were severely depressed.  Mean HAMD total score showed robust 
reductions even at the earliest time point measured (Mean HAMD 4.8 at Hour 12) and remained 
substantially lower through the end of infusion (Mean HAMD 3.3 at Hour 24, 1.8 at Hour 36, 
2.3 at Hour 48, and 1.8 at Hour 60).  Other end points showed similar improvements.  
1.2 
Product Background and Clinical Information 
Ganaxolone is the 3-methylated synthetic analog of the progesterone metabolite 
allopregnanolone.  Allopregnanolone exhibits potent anxiolytic, antidepressant, antiepileptic, and 
sedative activity by virtue of its GABAA receptor modulating properties.  As with 
allopregnanolone, ganaxolone potentiation of the GABAA receptor occurs at a site distinct from 
the benzodiazepine site.  However, unlike allopregnanolone, ganaxolone cannot be converted to 
a hormonally active steroid.8  Ganaxolone has been studied in completed and ongoing clinical 
trials in healthy adults, adult subjects with epilepsy, adults with post-traumatic stress disorder 
(PTSD), adults with migraine, children with refractory epilepsy and seizure disorders including 
female pediatric subjects with protocadherin 19 (PCDH19) epilepsy, and children with Fragile X 
Syndrome.

1.2.1 
Ganaxolone:  Oral Administration 
As of 
 approximately 1,588 unique subjects have received treatment with 
ganaxolone oral formulations in ongoing and completed clinical trials ranging in duration from 
1 day to more than 2 years, using doses from 50 to 2,000 mg/day.  Of these, 1,148 unique 
subjects have received ganaxolone oral formulation in completed studies.  In 19 completed 
Phase 1 studies, 289 healthy subjects received ganaxolone orally at doses of 50 to 2,000 mg/day 
for periods of up to 2 weeks.  Ganaxolone when given at doses 1,000 mg BID to healthy 
volunteers resulted in average Cmax and Cmin concentrations of 262 ng/ml and 57 ng/ml.  
In the 18 completed Phase 2 clinical studies, 859 unique subjects have received oral ganaxolone 
at doses up to 1,500 mg/day including 169 adult subjects with epilepsy, 135 pediatric subjects 
with seizure disorders, 59 pediatric subjects with Fragile X syndrome, 393 adult subjects with 
migraine, and 103 subjects with PTSD. 
In clinical trials of ganaxolone, adverse events (AEs) related to the GABAergic mechanism of 
action such as dizziness, sedation and sedation-related AEs (fatigue, somnolence), ataxia and 
diplopia, were reported more commonly in subjects receiving ganaxolone than placebo.  In 
general, the frequency of these events was dose related.  Most of these effects were reported as 
mild or moderate in severity and were reversible after dose decrease or drug discontinuation.  
In the largest clinical trial conducted so far, Study 1042-0603, a Phase 3 trial of ganaxolone in 
adults with drug-refractory partial onset seizures, the safety profile of ganaxolone was consistent 
with previously conducted studies.  In the double-blind portion of this study, 359 subjects were 
randomized to receive oral ganaxolone (900 mg twice a day) or placebo for 14 weeks.  Overall, 
ganaxolone was generally safe and well tolerated with no imbalance between the ganaxolone and 
placebo group in the number of subjects with serious adverse events (SAEs) (5% vs 5.1%).  The 
most common AEs (> 5%) reported at greater rates than placebo were somnolence (23.5% vs 
4.5%), dizziness (19.6% vs 4.5%), and fatigue (11.7% vs 6.8%).  Most of these AEs were rated 
as mild in severity.  There were 44 (25%) subjects treated with ganaxolone that discontinued the 
study compared with 26 (14%) subjects on placebo.  The most common reason for 
discontinuation was AE.  Nine subjects experienced SAEs in placebo and ganaxolone groups 
each.  
In the ganaxolone development program overall, no clinically significant trends in 
electrocardiogram (ECG) intervals, vital signs, or physical or neurological examinations have 
been noted, and no mean changes from baseline in clinical laboratory results have been 
identified.  Overall, there have been only a few clinically significant individual changes from 
baseline in clinical laboratory measurements in clinical trials of ganaxolone.  In the completed 
placebo-controlled Phase 1, 2 and 3 studies, 0.32% of subjects treated with ganaxolone and 
0.31% of subjects treated with placebo exhibited elevated liver function tests during the study 
(> 3 times the upper limit of normal [ULN] aspartate aminotransferase [AST] and/or alanine 
aminotransferase [ALT]).  There have been no cases of Hy’s Law in the ganaxolone 
development program.  In controlled clinical trials of ganaxolone, 1.1% of subjects receiving 
placebo and 2.0% of subjects receiving ganaxolone reported an AE of rash or papular rash.  Most 
rashes improved either while the drug was continued or following discontinuation.  Two subjects

paiiicipating in the Phase 2 study investigating ganaxolone in treatment of epilepsy developed an 
SAE of rash. Both events resolved after discontinuation of the study diug. 
It is not known if ganaxolone is excreted in breast milk. After cessation of the infusion, plasma 
ganaxolone levels are expected to di·op rapidly, but it is possible that low sub-therapeutic levels 
persist for several days as ganaxolone is slowly released from tissues. Therefore, a washout 
period of 45 days is required following cessation of ganaxolone ti·eatment before breast-feeding. 
Previous toxicology studies in animals focusing on prenatal and neonatal development have not 
demonstrated toxicities associated with ganaxolone. Ganaxolone has been administered orally to 
infants with severe fonns of epilepsy as early as 4 months of age. 
In clinical trials involving administi·ation of oral ganaxolone over several weeks, the study diug 
has been tapered off over a 1 to 2-week period. There have been no repo1is of withdrawal 
symptoms emerging after cessation of ganaxolone. 
1.2.2 
Ganaxolone: Intravenous Administration 
Preclinical studies and a study in 36 healthy volunteers assessing safety, phaim acokinetics (PK), 
and phan nacodynainics of inti·avenously (IV) administered ganaxolone have been completed. 
Preclinical toxicity studies showed IV anaxolone to be enerall safe and AEs consistent with 
ex ected dose-related sedation. 
There was no evidence of local initation when ganaxolone was given intra- or 
pen venous y in preclinical studies. Fmthennore, IV ganaxolone did not cause hemolysis and 
was compatible with human plasma. 
Six subjects repo1ied ti·eatment emergent AEs in Stage 1 and 2. No single AE was seen twice. 
Only 1 event (headache) was considered by the investigator to be related to ganaxolone. None of 
the ti·eatment emergent AEs were serious, and all were of mild intensity. No clinically 
meaningful mean changes in laborato1y test results, vital signs, or ECG parameters occw-red in 
any cohort.

Pharmacokinetic data from Study 1042-0405 showed that a bolus infusion of 30 mg ganaxolone 
over 5-minutes led to peak concentration levels (Cmax) of > 1,000 ng/ml with no safety concerns.  
Infusion of 30 mg/h for 1 hour and 20 mg/h for 4 hours led to concentrations of 258 and 
215 ng/mL respectively, again without any safety concerns.  This is consistent with findings 
from previous studies with the oral formulation of ganaxolone, in which Cmax levels of up to 
200 to 300 ng/mL were commonly observed and were not associated with major safety findings 
or toxicity (apart from sedation-related effects).

2 STUDY OBJECTIVES AND PURPOSE 
2.1 
Rationale for the Study 
Rapidly declining plasma levels of allopregnanolone and other neurosteroids after childbirth are 
thought to be linked to triggering depression in women who are vulnerable to development of 
this condition.  Ganaxolone, a synthetic analog of allopregnanolone, may provide benefit to these 
women.  This study is intended to explore the safety and efficacy of ganaxolone in women with 
PPD.  
2.2 
Study Objectives 
2.2.1 
Objectives of the Open-label Safety Part 
2.2.1.1 
Safety Objective 
To assess the safety and tolerability of ganaxolone in women with PPD as determined by AEs 
and changes from baseline in laboratory measures, vital signs, Columbia Suicide Severity Rating 
Scale (CSSRS), electrocardiogram (ECG), Stanford Sleepiness Scale (SSS), and physical 
examination.  
2.2.1.2 
Dosing Objective  
To develop an optimal dosing regimen for the double-blind placebo-controlled (DBPC) part of 
the study.  Adverse events and other safety data, including sedation and dosing changes, will be

3 STUDY DESIGN 
3.1 
Study Design and Study Population 
This is a Phase 2, multicenter study in women with PPD consisting of 2 dosing parts: an initial 
open-label safety part, and a DBPC part.   
The investigator has the flexibility to adjust the dose amount and/or timing of dosing if the 
subject experiences untoward effects during the open-label part, by reducing the dose first to a 
lower level and possibly increasing it later, if tolerance to the untoward effects develops. 
Enrollment and dosing will be completed in the open-label safety part before proceeding to the 
DBPC part.  The goal of the open-label part is to explore the safety of IV and oral ganaxolone in 
this population, and identify a dosing regimen for the DBPC part.   
Open-label Part 
For the open-label safety part, approximately 172 women aged 18 to 48 years with PPD will be 
screened to enroll approximately 88 subjects.    
In the first group with approximately 8 subjects, ganaxolone will be titrated to a daily dose of 
900 mg/day over 10 days, followed by a taper over 4 days.  This dosing group is called the 
open-label 3 times daily (OL TID) group.  
The second group with approximately 20 subjects will receive ganaxolone administered at 
bedtime (QHS).  For these subjects, ganaxolone will be titrated to a QHS dose of 675 mg over 
4 days, which is then maintained until Day 10, followed by a taper over 4 days.  This dosing 
group is called the OL QHS group.   
The third group with approximately 20 subjects will receive ganaxolone administered at a dose 
of 675 mg QHS for 28 days, followed by a taper over 4 days.  This dosing group is called the 
OL QHS 4-week dosing group. 
The fourth group with approximately 20 subjects will receive on the first 2 days, ganaxolone 
capsules 675 mg at dinner time and 675 mg at bedtime (for a total of 1,350 mg per day on the 
first 2 days), followed by 26 days of ganaxolone capsules 1,125 mg at dinner time (high fat diet), 
and a taper over 4 days.  This dosing group is called the OL 1,125 mg group.  
The fifth group with approximately 20 subjects will receive ganaxolone as IV 12 mg bolus over 
2 minutes at approximately 4 pm of the first day, followed by ganaxolone oral suspension 
750 mg at dinner time (high fat diet), and 750 mg at bedtime (with a high fat snack) for a total of 
1,512 mg on Day 1.  On Day 2, subjects will receive ganaxolone oral suspension 750 mg at 
dinner time and 750 mg at bedtime, for a total of 1,500 mg, followed by 26 days of ganaxolone 
oral suspension 1,000 mg at dinner time and a taper over 4 days. This dosing group is called the 
OL Bolus-oral group.

Double-blind Placebo-controlled Part 
Marinus Phrumaceuticals, Inc. 
Version 5.0 / 22 Oct 2018 
For the DBPC part, approximately 100 women with PPD aged 18 to 48 years will be screened to 
randomize 50 women in a 1: 1 ratio to receive ganaxolone or matching placebo for 14 days. 
3.2 
Rationale for Study Design 
Rapid changes in allopregnanolone and other neurosteroid levels during and after pregnancy are 
thought to contribute to the biological underpinnings of PPD. There are also data suggesting that 
the sensitivity of the GABA system is altered during pregnancy and after childbirth, possibly as a 
result of changes in the circulating neurosteroid levels, and that there may be a state of 
neurosteroid withdrawal after pregnancy.9 Ganaxolone may alleviate PPD by increasing 
neurosteroid activity. 
A previous study with IV allopregnanolone showed that allopregnanolone has the potential to 
produce a rapid and robust antidepressant activity.7 We hypothesize that a similar antidepressant 
activity may be obtained with IV and oral ganaxolone. 
Although ganaxolone has been administered to more than 1,500 subjects, there have been no 
previous studies exploring the safety or efficacy of ganaxolone in PPD or other mood disorders 
m women. 
Various dose amounts, fonnulations, dosing schemes and treatment durations will be evaluated 
in the Open-label pa1t to infonn the choice of the treatment scheme for the DBPC pa1t. 
Approximately 8 or 20 subjects, depending on the group, will receive open-label ganaxolone to 
evaluate safety, tolerability, kinetics and efficacy of the drng in women diagnosed with PPD. 
Assessments of AEs, laborato1y , ECG, and clinical ratings for safety and efficacy will be 
gathered to evaluate the possible differential effect of the various dosing schemes. 
A double-blind evaluation of safety and efficacy will follow the completion of the open-label 
pait. This study pait will utilize a randomized, parallel-group, placebo-controlled design in 
women diagnosed with PPD. Evaluations of safety and tolerability, as well as efficacy will 
utilize the same evaluation methods as in the open-label pait. The primaiy efficacy endpoint will 
be change from baseline in HAMD-17 of active vs placebo treatments. The concomitant use of 
antidepressants or no use of antidepressants will be stratified 1: 1 to emoll similar numbers of 
subjects in each strntum for both the ganaxolone and placebo treatment groups.

3.3 
Dose Selection  
Allopregnanolone levels increase gradually throughout pregnancy reaching peak mean 
concentrations at the end of pregnancy of about 15 to 60 ng/ml.  The levels then drop 
precipitously after delivery.3, 4, 10  We hypothesize that substitution of the low allopregnanolone 
levels with ganaxolone would alleviate or reverse the symptoms of PPD.  The target trough 
ganaxolone exposure level of approximately 50 ng/ml was chosen to achieve a level similar to 
that of allopregnanolone at the end of pregnancy.   
Open-label TID dosing group  
Ganaxolone doses are titrated for the OL TID dosing group from 225 mg on Day 1 to a daily 
dose of 900 mg starting on Day 7.  Previous studies have shown that the sedating effects of 
ganaxolone may be minimized via dose titration.  
With the proposed dosing regimen for the OL TID dosing group, the ganaxolone mean trough 
and peak plasma concentrations during the Days 8, 9, and 10 are predicted to fluctuate between 
40 ng/ml and 100 ng/ml respectively, based on PK modelling.  This dose range is considered to 
provide adequate ganaxolone plasma exposure from the point of view of testing whether the dose 
range of 50 to 60 ng/ml is necessary for alleviating the symptoms of PPD.  Based on the previous 
ganaxolone studies, plasma levels below 100 ng/ml have not been sedating in most subjects.  
The bedtime doses for the OL TID dosing group are selected to be higher than the daytime doses, 
and are expected to yield plasma mean peak concentrations up to 180 ng/ml during the night on 
Days 8, 9 and 10.  These levels may be sedating in some subjects.  Since disrupted sleep is a 
hallmark of depression, the potential sleep promoting effect of ganaxolone may in fact be 
beneficial.  
Approximately 8 subjects will be allocated for the OL TID group.   
Open-label QHS dosing group  
A QHS dosing group is included in the open-label part to explore whether QHS dosing only is 
well-tolerated and shows comparable therapeutic effect to the TID dosing.  In the QHS dosing 
group, the trough ganaxolone levels are expected to be below 40 ng/ml.  However, constant 
plasma exposures may not be necessary for antidepressant effect but the therapeutic efficacy 
under this dosing scenario could arise via other mechanisms, such as modulation of sleep 
architecture.  
Approximately 20 subjects will be allocated to the OL QHS group.  The enrollment for the OL 
QHS group will start after all subjects allocated to the OL TID group have started their dosing.  
Open-label QHS 4-week dosing group  
A QHS 4-week dosing group is included in the open-label part to explore whether administering 
ganaxolone at 675 mg QHS is well-tolerated and shows sustained therapeutic effect over 
4-weeks of dosing, and whether the therapeutic effects are maintained over a 3-month follow-up 
period.

Approximately 20 subjects will be allocated to the OL QHS 4-week dosing group.  The 
enrollment for the OL QHS 4-week group will start after all subjects allocated to the OL QHS 
group have started their dosing.  
Open-label 1,125 mg dosing group  
The OL 1,125 mg dosing group is included in the open-label part to explore whether 
administering ganaxolone orally at doses up to 1,125 mg per day over 4 weeks (including 
1,350 mg in the first 2 days) are safe and well-tolerated and show sustained effects, and whether 
the therapeutic effects are maintained over a 6-week follow-up period.  
The two evening 675 mg oral doses, within 3 hours of each other on Day 1 are expected to 
provide mean Cmax plasma concentrations of approximately 250-300 ng/mL, which may be 
mildly sedating.  Twin evening dosing on Day 2 is expected to lead to similar exposure.  In 
previous studies, ganaxolone has been given up to a daily dose of 2000 mg, and at single doses 
of 1000 mg.  Based on previous experience, this dose is expected to be safe.  
 
Approximately 20 subjects will be allocated to the OL 1,125 mg dosing group.  The enrollment 
for the OL 1,125 mg group will start after all subjects allocated to the OL QHS 4-week group 
have started their dosing.  
Open-label IV Bolus-oral dosing group  
The OL IV Bolus-oral dosing group is included in the open-label part to explore whether 
administering IV 12 mg ganaxolone bolus followed by oral suspension dosing of up to 1,000 mg 
per day (including up to 1,500 mg in the first 2 days) is safe and well-tolerated, and shows 
sustained therapeutic effect over 4 weeks of dosing, and whether the therapeutic effects are 
maintained over a 6-week follow-up period.  
This initial bolus infusion is targeted to provide a fast onset of antidepressant activity by delivery 
of rapid plasma exposures to ganaxolone.  Together with the two evening 750 mg oral doses 
within 3 hours of each other, Day 1 dosing is expected to provide mean Cmax plasma 
concentrations of approximately 250-300 ng/mL, which may be mildly sedating.  Twin evening 
dosing on Day 2 is expected to lead to similar exposure.  In previous studies, ganaxolone has 
been given up to a daily dose of 2,000 mg, and at single doses of 1,000 mg.  Based on previous 
experience, this dose is expected to be safe.   
 
Approximately 20 subjects will be allocated to the OL Bolus-oral dosing group.  The enrollment 
for the OL Bolus-oral group will start after all subjects allocated to the OL 1,125 mg group have 
started their dosing.  
Dose Justification in the Context of Previous Experience with IV Ganaxolone 
In Study 1042-0405, a completed Phase 1 study in healthy volunteers investigating the safety of 
IV ganaxolone, the highest bolus dose tested was 30 mg, which was infused over 5 minutes (the 
same rate [6 mg/min] as in the OL Bolus-oral group).  This dose led to peak concentration levels 
(Cmax) of > 1,000 ng/mL, with no safety concerns (except sedation).  This safety profile is 
consistent with findings from previous studies with the oral formulation of ganaxolone, where

Page 28 of 131 
Cmax levels of up to 200 to 300 ng/mL were commonly observed and were not associated with 
major safety findings or toxicity (apart from sedation-related effects).  
Double-blind Placebo-controlled (DBPC) Part 
For the DBPC part of the study, the targeted ganaxolone plasma concentrations and the final 
dosing formulations will be determined based on the safety and efficacy results of the open-label 
safety data (Section 3.5).  Additional information for the dose-selection for the DBPC part may 
be obtained from the ongoing phase 2A study in PPD with the ganaxolone IV formulation 
(conducted under IND No. 106104).  
Blinding Scheme 
Subjects will be randomized to ganaxolone or placebo in a 1:1 ratio.  The randomization scheme 
will be prepared by an independent third-party vendor.  Treatment assignments will be obtained 
by the investigator (or designee) via an Interactive Voice and/or Web Response System (IxRS).  
The placebo infusion and placebo capsules are identical to the ganaxolone infusion and capsules, 
respectively, in their appearance.  An unblinded study pharmacist at the investigative site will 
prepare the ganaxolone and placebo IV solutions and allocate capsule supply for the DBPC part.  
Members of the DRC will be unblinded.  All other study personnel, including persons involved 
in the evaluation of the study subjects (e.g., investigators, sub-investigators, and 
physicians/nurses), with the exception of the study pharmacist, will remain blinded at all times, 
except in case of an emergency.  Subjects will be blinded.   
3.4 
Study Duration  
For both the open-label safety OL TID and OL QHS groups, and the DBPC part of the study, the 
screening period will be up to 2 weeks, followed by a 14-day outpatient treatment period and a 
14-day follow-up period.  For the OL QHS 4-week dosing group, the screening period will be up 
to 2 weeks, followed by a 28-day outpatient treatment period, a 4-day taper and a 3-month 
follow-up period.  For the OL 1,125 mg and OL Bolus-Oral dosing groups,the screening period 
of up to 2 weeks will be followed by a 28-day outpatient treatment period, a 4-day taper, and a 
6-week follow-up period (from Day 29). 
3.5 
Planned Analyses 
3.5.1 
Analysis After Completion of the Open Label Part  
At the completion of the open-label part, adverse events and other safety data, including sedation 
and dosing changes, will be adjudicated by the DRC before proceeding to the DBPC part of the 
study.  These data will be used to determine the dosing regimen for the DBPC part.   
3.5.2 
Analyses After Completion of the Double-blind Placebo-controlled Part 
After completion of the DBPC part, the data will be evaluated by an independent DRC.  Based 
on the analysis and recommendation by the DRC, the study may be closed at that point, or an 
additional approximately 50 women with PPD will be treated with ganaxolone or placebo under

4.4 
Discontinuation of Subjects 
A subject may withdraw from the study at any time for any reason without prejudice to their 
future medical care by the physician or at the institution.  The investigator or sponsor may 
withdraw the subject at any time (e.g., in the interest of subject safety).  The investigator is 
encouraged to discuss withdrawal of a subject from the investigational product with the medical 
monitor when possible.  Withdrawn subjects who have not received IP will be replaced. 
If the investigational product is discontinued, regardless of the reason, the evaluations listed for 
Day 10 for OL TID and OL QHS groups or Day 29 for the OL QHS 4-week, OL 1,125 mg, and 
OL Bolus-oral groups are to be performed as completely as possible.  Whenever possible, all 
discontinued subjects should also undergo the protocol-specified follow-ups.  Comments 
(spontaneous or elicited), complaints, or AEs reported by the subject must be recorded in the 
source documents.  The reason for discontinuation and the date and time of discontinuation of 
the investigational product must be recorded in the electronic case report form (eCRF) and 
source documents.  
4.4.1 
Subject Withdrawal Criteria 
All subjects reserve the right to withdraw from the clinical study at any time, as stated in the 
informed consent form (ICF).  The investigator may discontinue subjects from the clinical study 
for any of the following reasons: 
1. Electrocardiogram evidence of QT prolongation (QTcF > 530 msec, or an increase of QTcF 
> 60 msec above baseline to a value > 480 msec on the 12-lead ECG, confirmed on a repeat 
12-lead ECG taken after resting at least 5 minutes in a supine or semi-recumbent position 
after the original finding of prolonged QTcF).  
2. It is the investigator’s opinion that it is not in the subject’s best interest to continue in the 
study. 
3. Any subject who exhibits any Suicidal Behavior or Suicidal Ideation (e.g., subject answers 
“yes” to question 4 or 5 in the Suicidal Ideation section of the CSSRS).  These subjects 
should be evaluated by a psychiatrist immediately.

4. Rash that is clinically significant and considered to be related to the study drug (e.g., 
morbiliform, urticarial, papular).  
5. Subject experiences an SAE considered to be related to the study drug 
Decisions to discontinue the study will be made at each participating site by the principal 
investigator.  If feasible, the reason for discontinuation should be discussed with the medical 
monitor.  
4.4.2 
Reasons for Discontinuation 
The reason for withdrawal must be determined by the investigator and recorded in the subject’s 
medical record and on the eCRF.  If a subject is withdrawn for more than 1 reason, each reason 
should be documented in the source document and the most clinically relevant reason should be 
entered on the eCRF.  
Reasons for discontinuation include but are not limited to: 
 AE 
 Protocol deviation 
 Withdrawal of consent by subject 
 Lost to follow-up 
 Lack of efficacy 
 Other (If “Other” is selected, the investigator must specify the reason on the eCRF) 
4.4.3 
Subjects “Lost to Follow-up” Prior to Last Scheduled Visit 
A minimum of 3 documented attempts must be made to contact any subject lost to follow-up at 
any time point prior to the last scheduled contact (office visit or telephone contact).  At least 1 of 
these documented attempts must include a written communication sent to the subject’s last 
known address via courier or mail (with an acknowledgement of receipt request) asking that she 
return to the site for final safety evaluations.  If contact is made but the subject refuses or is 
unable to come to the final safety evaluation, it should be documented in the eCRF.

5 PRIOR AND CONCOMITANT TREATMENT 
All non-study treatments (including herbal treatments and vitamins) received within 60 days 
prior to the screening visit (Visit 1) and through the final study contact (including 
protocol-defined follow-up period) must be recorded on the appropriate eCRF page. 
5.1 
Prior Pharmacological Treatment 
Prior pharmacological treatment includes all treatments (including herbal treatments and 
vitamins) that the subject received and stopped within 60 days of the date of the screening visit.  
For example, if the subject had been treated with sertraline during pregnancy but it was 
discontinued 3 weeks prior to the screening visit, this medication would be recorded on the prior 
medication eCRF page.  
5.2 
Concomitant Pharmacological Treatment  
Concomitant treatment refers to all treatments (including herbal treatment and vitamins) taken 
between the screening visit and the end of the follow-up period regardless of the start date of the 
concomitant medication.  For example, if the subject was started on a prenatal vitamin and it was 
continued through the study period, this treatment would be recorded on the concomitant 
medication eCRF page.  
5.3 
Concomitant Psychological Treatment 
Concomitant psychological treatment refers to all psychological care the subject received from 
the time of the screening visit through the end of the follow-up period.  Concomitant 
psychological treatment information must be recorded on the concomitant psychological 
treatments eCRF page. 
5.3.1 
Permitted Treatment 
5.3.1.1 
Permitted Psychological Treatments 
The subject may continue their current form of psychological treatment (e.g., cognitive 
behavioral therapy, psychodynamic psychotherapy, supportive psychotherapy) throughout the 
treatment period.  Initiation of a new therapy (a new treatment modality or switching a therapist) 
is prohibited during the treatment period.  After the treatment period, psychotherapy should be 
continued using the same modality and at the same frequency as during the treatment period, 
provided that this is medically justified, in order to be able to determine whether there are 
sustained effects from the treatment the over the 30-, 42-, or 90-day follow-up periods.  Any 
changes must be recorded on the concomitant psychological treatments eCRF page.   
5.3.1.2 
Permitted Antidepressant Treatments  
The subject may continue their current SSRI, serotonin and norepinephrine reuptake inhibitors, 
bupropion, other serotonin, or norepinephrine modulating antidepressant (e.g., vortioxetine, 
mirtazapine) treatment, provided the regimen conforms to the standard of care and the 
medication was started at least 21 days before the screening visit, and there has not been a dose

change within 7 days of the screening visit.  The antidepressant medication must have been 
approved for treatment of major depressive disorder by the United States (US) Food and Drug 
Administration (FDA).  Monoamine inhibitors are prohibited (including all formulations of 
selegiline).  Tricyclic antidepressant medications will be decided on a case-by-case basis after 
discussion with the medical monitor.  
5.3.1.3 
Other Permitted Treatments 
The subject may continue her current non-psychiatric medications with the exception of 
medications that are strong inducers or inhibitors of CYP3A4 (Appendix 1. ).  
The subject may use diphenhydramine 25 to 50 mg, trazodone 25 to 50 mg, or doxepine 3 to 
5 mg for severe insomnia as needed.  Only 1 dose of 1 of the medications is allowed per night.  
Other hypnotics, such as zolpidem or zaleplon, are prohibited.  
If the subject is treated with an atypical antipsychotic medication that was started with the 
purpose of augmenting the therapeutic effect of an antidepressant (i.e., the antipsychotic is not 
intended for treatment of psychosis or mood stabilization, and it is used in combination with an 
antidepressant), and the medication has been approved by the US Food and Drug Administration 
as an add-on therapy for major depression, she may continue this treatment throughout the study 
period provided that the medication is taken within the approved dose range.  Examples of such 
treatments would be quetiapine 50 mg at bedtime and aripiprazole 10 mg daily.  However, the 
antipsychotic medication must have been started at least 21 days before screening, and there 
should not have been a dose change within 7 days of screening.  
Other medications and medication combinations should be discussed with the medical monitor 
before enrolling the subject in the study.  
After completion of the treatment period, any changes to the antidepressant or antianxiety 
medication regimen are not prohibited, but investigators are encouraged to maintain such drugs 
at stable doses if possible.  Any changes in the medication regimen must be recorded on the 
concomitant medication eCRF page.   
5.3.2 
Prohibited Treatments 
The following classes of medications and treatments are prohibited during the study.  If the 
subject has been taking any of these medications before enrollment, there should be a 
medication-free period of a minimum of 5 days or 5 half-lives of that medication, whichever is 
longer, before admission to the unit.  In general, subjects who require extensive washouts may 
not be candidates for participation and those cases should be discussed with the medical monitor.  
 Benzodiazepines and barbiturates 
 Gabapentin and pregabalin 
 Anticonvulsants and mood stabilizers 
 All hypnotics and sleep aids (with the exception of low-dose diphenhydramine, doxepin, and 
trazodone as described above)

6.2.1 
Allocation of Subjects to Treatment 
Subject numbers are assigned to all subjects as they consent to take part in the study.  Within 
each site (numbered uniquely within a protocol), the subject number is assigned by the 
Electronic Data Capture (EDC) system to subjects according to the sequence of presentation for 
study participation.  
In the open-label part, the first approximately 8 subjects will be assigned to OL TID dosing 
group.  After approximately 8 subjects have started dosing in the OL TID group, the dosing for 
the OL QHS group will commence.  Approximately 20 subjects will be dosed for the OL QHS 
group.  After approximately 20 subjects have started dosing in the OL QHS group, the 
enrollment into the OL QHS 4-week group will commence.  After approximately 20 subjects 
have started dosing in the OL QHS 4-week group, enrollment into the OL 1,125 mg group will 
commence.  Approximately 20 subjects will be dosed for the OL 1,125 mg group.  After 
approximately 20 subjects have started dosing in the OL 1,125 mg group, enrollment into the OL 
Bolus-oral group will commence.  Approximately 20 subjects will be dosed for the OL 
Bolus-oral group. 
In the DBPC part, subjects will be randomized to receive ganaxolone or matching placebo in a 
1:1 ratio.  Randomization will be stratified by the use of concomitant antidepressants so that the 
number of subjects who are treated with antidepressants and who are not treated with 
antidepressants will be similar in each treatment group. 
After being enrolled, a subject will be replaced only if she discontinues prior to receiving study 
treatment. 
6.2.2 
Dosing for the Open-label Treatment Part – OL TID Group 
Subjects start taking the study drug at bedtime (HS) on Day 1 (enrollment).  The first dose to be 
taken will be one 225 mg capsule.  The next evening (Day 2), the dose will be increased to 
450 mg (2 capsules) to be taken HS.  This dose is taken on Day 2 and Day 3.

Dose Adjustments During Open-label  
Adjusting doses for the OL TID dosing group 
During the study the investigator has the opportunity to de-escalate, skip dose escalation and 
re-escalate during the titration on Days 1 to 10 at the scheduled study visits if the subject is 
experiencing adverse events.  The dose adjustments done at the study visits should follow the 
schedule outlined in Table 1.  The investigator should de-escalate to a previous dosing schedule, 
repeat the current dosing schedule or re-escalate to dosing scheme outline in the table.  Other 
flexible adjustments are not allowed.  
Example 1:  
If the subject at Day 4 visit reports adverse effects (e.g., sedation) with the 450 mg QHS dose, 
the investigator may decrease the dose to 225 mg QHS (de-escalation) or continue the 450 mg 
QHS dose (skip dose escalation).  The investigator may then attempt to re-escalate the dose to 
the next dose level at the next visit (Day 7).  If the investigator opted to maintain the 450 mg 
QHS dose at the Day 4 visit, the investigator may then increase the dose to the next scheduled 
dose level (225 mg QAM and 450 mg QHS) at Day 7 visit provided that the subject has 
developed a tolerance to the sedative effects.  
Example 2:  
If the subject at study visit on Day 7 reports intolerable sedation after the morning dose, the 
investigator may choose to drop the dosing to 450 mg QHS or skip the escalation and maintain 
the current dosing (225 mg QAM and 450 mg QHS). 
Subjects who do not reach the 900 mg daily dose (225 mg QAM, 225 mg Q2PM and 450 mg 
QHS) will be tapered off the study medication by reducing the dose by about 225 mg per day or 
every other day over the Days 11 to 14.  The QHS dose should be the last dose before the drug is 
discontinued completely.  
The subjects who do not tolerate the first dose of 225 mg QHS should be considered for 
discontinuation.  
All doses taken must be recorded in the eCRF. 
If the study visit falls on the weekend, or if the subject is not able to come to the study scheduled 
study visit, each visit has a window + 3 days.  Under this scenario, the subject would continue at 
the prescribed dose level until the study visit.  
Adjusting doses for the OL QHS dosing group 
During the study the investigator has the opportunity to defer a dose escalation to 675 mg at 
Day 4 Visit if the subject reports adverse events (e.g., sedation in the morning) and attempt 
escalation at Day 7 Visit or continue the dosing at 450 mg QHS until Day 10 Visit.

Adjusting doses for the OL QHS 4 week dosing group 
The investigator has the flexibility to adjust treatment reducing the dose to one or two capsules, 
if the subject experiences sedation, dizziness or other untoward effects during the OL part.  
 
Adjusting dose and/or timings for the OL 1,125 mg dosing group 
The investigator has the flexibility to adjust dose by reducing the dose to 450 mg (2 capsules) at 
the second of Day 1 doses (at HS) and/or at either of Day 2 doses, and/or reduce to 900 mg, 
675 mg, or 450 mg on Day 3 through Day 28 (at dinner time) if subject experiences sedation, 
dizziness or other untoward effects during the OL part.  The investigator can also change the 
timing of the evening dose bringing it closer to bedtime and taking it with a fatty snack instead of 
dinner.  Any further adjustments as well as adjusted taper period doses should be discussed with 
the medical monitor.  The investigator may increase the dose back to default levels if tolerance 
develops to the untoward effects.  
Adjusting dose and/or timings for the OL Bolus-oral dosing group  
The investigator has the flexibility to adjust dose by reducing the dose to 500 mg (10 mL) for the 
second of Day 1 doses (at HS) and/or either of Day 2 doses, and/or reduce to 750 mg (15 mL), or 
500 mg (10 mL) at dinner time on Day 3 through Day 28 if subject experiences sedation, 
dizziness or other untoward effects during the OL part.  The investigator can also change the 
timing of the evening dose bringing it closer to bedtime and taking it with a fatty snack instead of 
dinner.  Any further adjustments as well as adjusted taper period doses should be discussed with 
the medical monitor.  The investigator may increase the dose back to default levels if tolerance 
develops to the untoward effects.  
6.2.8 
Blinding 
During the DBPC part, subjects randomized to placebo will receive placebo capsules which are 
identical to the active ganaxolone capsules.  
6.3 
Labeling, Packaging, and Storage 
6.3.1 
Labeling 
Bottles will be labeled before shipping to the sites.  In the DBPC part, the contents of each bottle 
will be blinded using labels.  The randomization schedule will match a subject number to a bottle 
number.  
6.3.2 
Packaging and Dispensing the Study Drug 
Ganaxolone capsules and matching placebos will be provided in HDPE bottles. 
All packaging and labeling operations will be performed according to good manufacturing 
practice (GMP) and good clinical practice (GCP) guidelines.  Investigational products are 
prepared and distributed by the site pharmacist.

The site pharmacy or delegated site staff will be responsible for dispensing the study treatment to 
the subject.  Sufficient amount of supplies will be provided to the subject until the next study 
visit and a minimum of 3 days’ overage to cover for weekends, study site closures and 
unexpected need for rescheduling the study visit.  
Detailed instructions on when to take the medication and a reminder to take oral study 
medication within ± 15 minutes of a fatty meal or snack (e.g., fatty yogurt, nuts, avocado) and 
with 240 mL (8 oz) of water will be provided to the subject. 
6.3.3 
Storage 
The investigator has overall responsibility for ensuring that investigational products are stored in 
a secure, limited-access location.  Limited responsibility may be delegated to the pharmacist, but 
this delegation must be documented.  
The ganaxolone stock solution investigational product for the IV administration will be stored at 
refrigerated temperature 2ºC to 8ºC (36ºF to 46ºF).   
The 0.3-micron ganaxolone capsules (225 mg), oral suspension, and matching placebos are 
stored in HDPE bottles with a foil induction seal and child resistant closure at room temperature 
(15oC to 25oC; 60ºF to 75ºF).  
Temperature monitoring is required at the storage location to ensure that the investigational 
product is maintained within an established temperature range.  The investigator is responsible 
for ensuring that the temperature is monitored throughout the duration of the study and that 
records are maintained.  The temperature should be monitored continuously through use of either 
an in-house system, a mechanical recording device such as a calibrated chart recorder, or by 
manual means, such that both minimum and maximum thermometric values over a specific time 
period can be recorded and retrieved as required.  The sponsor or sponsor’s delegate must be 
notified immediately upon discovery of any excursion from the established range.  Temperature 
excursions will require site investigation as to cause and remediation.  The sponsor will 
determine the ultimate impact of excursions on the investigational product and will provide 
supportive documentation as necessary.  Under no circumstances should the product be 
dispensed to subjects until the impact has been determined and the product is deemed appropriate 
for use by the sponsor. 
The sponsor or sponsor’s delegate should be notified immediately if there are any changes to the 
storage area of the investigational product that could affect the integrity of the product(s), e.g., 
fumigation of a storage room. 
6.4 
Drug Accountability 
Drug kits containing the study drug and supplies needed for each subject for the entire study will 
be supplied to the investigational site by the sponsor or a distributor on behalf of the sponsor.  
The pharmacist or delegated site staff will inventory and acknowledge receipt of all shipments of 
the kits.  The study drugs must be kept in a locked area with restricted access and stored and 
handled in accordance with the manufacturers’ instructions.  The pharmacist will also keep

accurate records of the quantities of study drug dispensed and used.  The pharmacist is 
responsible for all drug supplies; written documentation is mandatory.  The study monitor will 
periodically check the supplies of the study drug held by the pharmacist to verify accountability 
of all kits used.  The pharmacist will dispense the study drug according to the dosing plan.  Upon 
receiving study drugs, the principal investigator and the team members will administer them only 
to the identified subjects in this study, following the procedures described in this study protocol 
and documented in the appropriate eCRF.  At the conclusion of the study, all unused study drug 
will be returned or destroyed per the site’s Standard Operating Procedures (SOP) or instructions 
from the sponsor.  The sponsor will verify that a final report of drug accountability to the 
unit-dose level is prepared and maintained in the principal investigator’s study file. 
6.5 
Drug Administration 
Oral doses of the investigational product should be taken within ±15 minutes of a fatty meal or 
snack (e.g., fatty yogurt, nuts, avocado), and with 240 mL (8 oz) of water.   
For the IV bolus ganaxolone 12 mg in 24 mL will be administered over 2 minutes via an 
indwelling catheter or a butterfly, inserted in a vein on the arm or hand.  The investigational 
product should be given as continuous infusion as instructed.  The catheter should be flushed 
with saline at the end of the bolus infusion.  For details please see pharmacy manual.  
Subjects will be informed about possible side effects from the study medication and cautioned to 
avoid quick postural changes.  They should not carry the baby or sleep with the baby in the same 
bed due to the possible side-effect of dizziness and sedation.  Subjects will be advised not to 
drive, operate heavy machinery, or participate in any potentially hazardous activity during the 
study that requires full mental alertness until they are sure the medication is not affecting 
alertness.  They will also be cautioned that non-adherence to the dosing instructions (e.g., 
increasing the dose, taking the study medication doses too close together) could produce side 
effects.  
The interaction between alcohol and ganaxolone is not known.  Alcohol use is prohibited during 
the treatment period.  
The subject must have a reliable family member, significant other or a trusted friend who can 
take the role for being the primary childcare provider and a support person at home (including at 
nighttime) while the subject is participating in the trial, including for subjects who may stay 
overnight on the unit as part of the screening process and/or the PK subgroup.

7 STUDY PROCEDURES 
This is a Phase 2, multicenter study in women with postpartum depression (PPD) consisting of 
2 dosing parts: an initial open-label safety part and a DBPC part.   
For the open-label safety part, approximately 172 women 18 to 48 years of age with PPD will be 
screened to enroll approximately 88 subjects.  During this open-label safety part, for the first 
approximately 8 subjects, ganaxolone will be titrated to a daily dose of 900 mg/day over 10 days, 
followed by a taper over 4 days.  This dosing group is called OL TID group.  
For the next approximately 20 subjects, ganaxolone will be administered at QHS.  For these 
subjects, ganaxolone will be titrated to a QHS dose of 675 mg over 4 days which is then 
maintained until day 10, followed by a taper over 4 days. This dosing group is called OL QHS 
group. 
For the next approximately 20 subjects, ganaxolone will be administered at bedtime (QHS). For 
these subjects ganaxolone treatment will be a QHS dose of 675 mg over 28 days, followed by a 
taper over 4 days. This dosing group is called OL QHS 4-week group. 
The next approximately 20 subjects of the open-label safety part will receive on the first 2 days 
ganaxolone capsules 675 mg at dinner time and 675 mg at bedtime (for a total of 1,350 mg per 
day on the first 2 days) followed by 26 days of ganaxolone capsules 1,125 mg at dinner time, 
followed by a taper over 4 days.  This dosing group is called OL 1,125 mg group.  
For the next approximately 20 subjects of the open-label safety part, ganaxolone will be 
administered as IV bolus 12 mg over 2 minutes at approximately 4 pm on Day 1 followed by 
ganaxolone oral suspension 750 mg at dinner time and 750 mg at bedtime, for a total of 
1,512 mg on the first day. On Day 2 subjects will receive ganaxolone oral suspension 750 mg at 
dinner time and at 750 mg at bedtime, for a total of 1,500 mg, followed by 26 days of 
ganaxolone oral suspension 1000 mg at dinner time, followed by a taper over 4 days. This dosing 
group is called OL Bolus-Oral group. The investigator has the flexibility to adjust the dose 
and/or timing of the dose if the subject experiences sedation, dizziness or other untoward effects 
during the OL part (see Section 6.2.7).  
The open-label safety part will be enrolled, and dosing completed before proceeding to the 
DBPC part.  The goal of the open-label part is to explore safety of IV and oral ganaxolone in this 
population and identify a dosing regimen for the DBPC part. 
For the DBPC part, approximately 100 women with PPD 18 to 48 years of age will be screened 
to randomize 50 women in a 1:1 ratio to receive ganaxolone or matching placebo for 14 days.  
The dosing for the DBPC portion of the study will be decided based on the results of the 
open-label portion and recommendations of the DRC.  The DRC is comprised of Marinus’ Chief 
Medical Officer and 2 external physician experts.  The daily dose will not exceed 1,600 mg.  
Randomization will be stratified by the use of concomitant antidepressants so that the number of 
subjects who are treated with antidepressants and who are not treated with antidepressants will 
be similar in each treatment group.

 Schedule a SAFER interview if the subject meets the eligibility criteria.  The SAFER 
interview will be conducted during the screening period.  The investigational site must wait 
for the results of the SAFER interview before enrolling the subject into the treatment phase 
of the study (if a SAFER interview was conducted within 2 weeks for Marinus PPD study 
1042-PPD-2002 at the same investigative site the SAFER interview does not have to be 
repeated. In this instance the HAMD17 score from the SAFER interview can be used to 
qualify the subject for the study).  
 Screening period may be extended to 21 days with approval from the medical monitor (e.g., a 
laboratory sample was hemolyzed and had to be repeated causing a delay).

7.10 Study Evaluations and Procedures 
7.10.1 
Demographics, Medical History, and Other Baseline Characteristics 
Demographics, medical history, and other baseline characteristics will be collected and recorded 
on the appropriate sections of the eCRF at the time of the screening visit.  
7.10.2 
Informed Consent 
The nature of the study and its risks and benefits will be explained to the subject by the principal 
investigator or designated study personnel.  The purpose of this study will be discussed with the 
subject.  
7.10.3 
Eligibility Review 
An eligibility review will be conducted by the investigator at the visits specified in Table 8, 
using the subject inclusion and exclusion criteria as detailed in Section 4.  
7.10.4 
Prior Medication, Concomitant Medication and Concomitant Therapy Review 
At screening, prospective subjects will be asked about medications they have taken in the 
previous 60 days, including prescription medications, non-prescription medications, herbal 
medications, vitamins, and supplements.  At subsequent visits, the subjects will be asked about 
medications taken since the last visit.   
The medications that were taken within the past 60 days will be recorded.  The medications that 
were taken within the past 60 days but stopped before the screening visit are recorded on the 
prior medications eCRF page.  The medications that were taken during the study period between 
the screening visit and last follow-up visit, regardless of whether the medication was started 
during the study period or before the study period, are recorded on the concomitant medications 
eCRF page.  
The following data will be recorded for all medications used by the subject:  drug name, dose, 
regimen, route of administration, start and stop dates, and the indication for use.  
The type of psychological counseling the subject received from the time of screening through the 
last follow-up visit will be recorded on the Concomitant Psychological Treatment eCRF page.

The physical examination will be documented in the subject’s source documents and on the 
physical examination eCRF.  If a new clinically significant abnormal finding (i.e., not noted at 
screening) occurs after the screening examination, it must be captured as an AE and documented 
on the appropriate AE eCRF page.  
7.10.5.1 
12-lead Electrocardiogram 
A 12-lead ECG will be conducted as outlined above.  Before each measurement, the subject 
should be resting in a supine or semi-recumbent position for 10 minutes.  RR, PR, QRS, QTcF 
and QTcB will be collected.  ECGs will be measured with equipment calibrated as per the ECG 
vendors’ standard operating procedure.  The ECG results will be assessed by a qualified 
clinician.  The investigator’s assessment of normal or abnormal will be recorded and entered in 
the eCRF page.  If a new clinically significant abnormal finding (i.e., not noted at Screening) 
occurs after the Screening examination, it must be captured as an AE or SAE (if it meets criteria 
for an SAE – see Section 8) and documented on the appropriate AE eCRF page and, if an SAE, 
submitted to Marinus Safety Department on the SAE form.   
7.10.5.2 
Clinical Safety Laboratory Evaluations  
The name and address of the central clinical laboratory for this study will be maintained in the 
Investigator’s files at each study site.  
All clinical laboratory assays will be performed according to the laboratory’s normal procedures.  
Reference ranges are to be supplied by the laboratory and will be used to assess the clinical 
laboratory data for clinical significance and out-of-range pathological changes.  The investigator 
should assess out-of-range clinical laboratory values for clinical significance, indicating if the 
values are clinically significant or not.  Abnormal clinical laboratory values, which are 
unexpected or not explained by the subject’s clinical condition, may, at the discretion of the 
investigator or sponsor, be repeated as soon as possible until confirmed, explained, or resolved. 
The following clinical laboratory assessments will be performed:  
Biochemistry  
Sodium, potassium, glucose, chloride, carbon dioxide, creatinine, total protein, blood urea 
nitrogen (BUN), albumin, total bilirubin (with reflex fractionation to direct and indirect bilirubin 
if total bilirubin is elevated and outside of the normal range), ALT, AST, alkaline phosphatase, 
thyroid stimulating hormone (with reflex to free T4 if thyroid stimulating hormone (TSH) is

outside of the normal range).  The investigator may determine serum β human chorionic 
gonadotropin (HCG) levels to confirm or exclude pregnancy.  
Hematology 
Hemoglobin, red blood cell count, mean corpuscular volume, mean corpuscular hemoglobin, 
mean corpuscular hemoglobin concentration, platelet count, and white blood cell count with 
differential.  
Subjects are not required to be fasting prior to collection of the blood samples. 
Urinalysis Including Pregnancy Test and Urine Drug Screen 
Leukocytes, nitrites, protein, blood, specific gravity, glucose, ketones, urine pregnancy test, urine 
drug screen (cannabis, opioids [including oxycodone, methadone and buprenorphine], cocaine, 
benzodiazepines, barbiturates, alcohol [ethanol], and phencyclidine).  
Confirmatory testing of positive drug screen findings using for example gas chromatography 
mass spectroscopy (GCMS) may be conducted.  
7.10.5.3 
Adverse Event Collection 
Please refer to Section 8, Adverse and Serious Adverse Events Assessment. 
7.10.5.4 
Vital Signs 
Vital signs including BP, pulse, respirations, and temperature (recorded in Celsius [°C]) will be 
monitored at the time points as outlined above.  Vital signs should be collected after the subject 
has been supine for 5 minutes.  If a vital sign measurement is scheduled at the same time as a 
blood draw, vital signs should be collected prior to the blood draw.  Blood pressure should be 
determined by an appropriately-sized cuff (using the same method, the same arm and in the same 
position throughout the study).  Any abnormal screening vital sign results considered to be 
clinically significant should be repeated to confirm the finding.  Height (in centimeters) will be 
collected at the screening visit.  Weight (in kilograms) will be collected as outlined above. 
Any clinically significant deviations from baseline vital signs that are deemed clinically 
significant in the opinion of the investigator are to be recorded as an AE.  
7.10.6 
Interviews, Questionnaires, and Scales 
The scales and assessments are listed in Appendix 2.  A separate file containing each 
scale/assessment will be provided to the site. 
7.10.6.1 
Mini International Neuropsychiatric Interview 7.0 
The Mini International Neuropsychiatric Interview (MINI) is a short, clinician-administered, 
structured diagnostic interview, with an administration time of approximately 15 minutes.  The 
MINI will be administered at the screening visit.

7.10.6.2 
The Hamilton Depression Rating Scale  
The HAMD is a commonly-used semi-structured clinician-rated instrument which assesses the 
range of symptoms that are most frequently observed in subjects with major depression.  HAMD 
has undergone a considerable amount of psychometric study and is accepted as a valid standard 
of symptom outcome assessment in studies of major depression.  In this study, the symptoms of 
depression will be scored using the original 17-item HAMD scale (HAMD17).  The 6-item 
version of this scale, known as HAMD6, will be derived from these data and used as an 
additional measure of changes in symptoms of depression.  The items on the HAMD6 scale are 
as follows:  depressed mood, work and interests, general somatic symptoms (tiredness), anxiety, 
guilt feelings, and psychomotor retardation.  Both HAMD6 and HAMD17 have been validated 
and used in many clinical trials of antidepressant medications.11  The use of the 6-item scale is 
justified because many items on the 17-item version cannot be expected to change over short 
period of time (e.g. weight).  
7.10.6.3 
Stanford Sleepiness Scale 
Stanford Sleepiness Scale (SSS) is a simple 8-item self-rated scale measuring level of sleepiness 
the subject is feeling.  Level 1 is “feeling active, vital, alert or wide-awake” level 7 is “no longer 
fighting sleep, sleep onset soon; having dream-like thoughts”; level 8 is sleeping.   
7.10.6.4 
Clinical Global Impression-Improvement and Clinical Global 
Impression-Severity  
The CGI-I is a 7-point scale that asks the clinician to assess how much the subject's illness has 
improved or worsened relative to a baseline state at the beginning of the intervention.  It is rated 
as:  1, very much improved; 2, much improved; 3, minimally improved; 4, no change; 5, 
minimally worse; 6, much worse; or 7, very much worse.  The Clinical Global Impression – 
Severity scale (CGI-S) is a 7-point scale that asks the clinician to rate the severity of the subject's 
depression at the time of assessment, relative to the clinician's past experience with subjects who 
have the same diagnosis.  Considering total clinical experience, a subject is assessed on severity 
of depression at the time of rating 1, normal, not at all ill; 2, borderline mentally ill; 3, mildly ill; 
4, moderately ill; 5, markedly ill; 6, severely ill; or 7, extremely ill. 
7.10.6.5 
Edinburgh Postnatal Depression Scale (EPDS) 
The EPDS is a 10-question self-rated instrument for assessment symptoms of PPD, such as 
worry, sleep, mood, and enjoyment.  Two questions assessing obsessive thoughts (Obsessive 
Thoughts Questionnaire) are added to this questionnaire (“How much of your time is occupied 
by obsessive thoughts over the past 24h?” and “How much distress do your obsessive 
thoughts cause you?), but they are not included in the calculation of the total EPDS score in the 
statistical analysis.  These 2 questions are rated on a 5-point scale.  
7.10.6.6 
Spielberg Trait-State Anxiety Inventory, 6 Item Version  
The STAI6 is a short questionnaire evaluating anxiety state.  The STAI6 has 6 questions, such as 
“I feel calm,” “I feel tense,” which the subject rates on a scale corresponding to “not at all,” 
“somewhat,” “moderately”, and “very much.”12

7.10.6.7 
SAFER Interview 
Staff psychiatrists or psychologists at the Massachusetts General Hospital Clinical Trials 
Network and Institute (CTNI) will perform independent remote SAFER interview (State versus 
trait; Assessability; Face validity; Ecological Validity; and Rule of 3 Ps (pervasive, persistent, 
and pathological)) for the screened subjects who are deemed eligible for enrollment to confirm 
validity of the diagnosis of PPD and eligibility for the study from depression perspective.  If the 
subject was screened by the SAFER team for Marinus study 1042-PPD-2002 and confirmed to 
have postpartum depression but the HAMD17 severity criteria were not met, the subject could be 
considered eligible for this study without repeating the SAFER interview provided that the 
original interview was done within 2 weeks of the screening visit for the current study. 
CTNI will also perform all HAMD ratings except the one done at screening. 
7.10.6.8 
Columbia Suicide Severity Rating Scale (CSSRS) 
The CSSRS is a unique, simple, and short method of assessing both behavior and ideation that 
tracks all suicidal events, and provides a summary of suicidality.13  It assesses the lethality of 
attempts and other features of ideation (frequency, duration, controllability, reasons for ideation, 
and deterrents) that are significantly predictive of completed suicide. 
7.10.7 
Pharmacokinetic Sampling 
Blood samples for pharmacokinetic analysis will be drawn at the times specified in Table 8 to 
allow determination of ganaxolone plasma levels.  
A sub-group of 6 subjects (to be called ‘PK sub-group’) in each of the OL 1,125 mg and OL 
Bolus-Oral groups will stay overnight on the unit between Day 1 and Day 2 to undergo 
comprehensive PK assessment as follows: for the OL 1,125 mg group plasma samples for PK 
analysis will be drawn at the following times after the first oral dose on Day 1 (i.e., the 675 mg 
oral capsules dose at 7 pm at dinner time; 0hr): +1hr, +2hr, +3hr (i.e., just prior to the 10 pm 675 
mg dose), at +4hr, +5hr, +6hr, and at 8 am on Day 2. For the OL Bolus-Oral group plasma 
samples for PK analyses will be drawn at the following times after the IV bolus on Day 1 (e.g., 
the 12 mg IV bolus at 4 pm; 0hr): +1hr, +2hr, +3hr (i.e., just prior to the first oral dose of 750 mg 
oral suspension at dinner time), at +4hr, +5hr, +6hr (i.e., just prior to the second 750 mg oral 
suspension evening dose), at + 7hr, +8hr, and at 8 am on Day 2. 
The first 6 consecutively enrolled subjects who are in units with overnight inpatient capabilities 
and who consent for inclusion in the PK subgroup will be included in the PK subgroup. 
 
7.10.8 
Neurosteroid Levels  
Blood samples for determination of neurosteroid levels (allopregnanolone and potentially other 
metabolites of progesterone) will be collected at time points specified in Table 8.

During this study, approximately 58 mL of blood will be drawn from all subjects during the 
study for the OL TID, OL QHS and Double-blind groups.  Approximately 112 mL of blood will 
be drawn from all subjects during the study for the OL QHS 4 week, OL 1,125 mg, and OL 
Bolus-Oral groups. 
Subjects in the ‘PK subgroup’ of the OL 1,125 mg and OL Bolus-oral groups (6 subjects in each 
subgroup) will have additional 6 and 8 samples, respectively, at 4 mL each, for a total of 
approximately 136 mL and 144 mL of blood drawn, respectively.  
7.10.10 
Safety Plan for Medical Emergencies 
If the subject exhibits suicidal ideation during the study visit (for example answering “yes” to 
questions 4 and 5 in the suicidal ideation part of the CSSRS) she must be evaluated by a 
psychiatrist immediately.  Suicidality assessment and the decision regarding further evaluation 
and treatment may be done by a psychiatrist principal investigator (or a sub-investigator). If a 
psychiatrist is not available at the study site, the site must have a plan how to access psychiatric 
care immediately, for example at a local emergency room or other acute care facility.  
Each investigative study site must provide 24-hour medical coverage to address questions from 
the subjects and respond to medical emergencies, such as suicidal ideation and adverse events, 
including during the off-duty hours. Each subject will be provided with a wallet card and 
information how to contact the study site at all hours.

8 ADVERSE AND SERIOUS ADVERSE EVENTS ASSESSMENT 
8.1 
Definition of Adverse Events, Period of Observation, Recording of Adverse 
Events 
An AE is any untoward medical occurrence in a clinical investigation subject administered a 
pharmaceutical product and that does not necessarily have a causal relationship with this 
treatment.  An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
(investigational) product, whether or not related to the medicinal (investigational) product 
(International Council on Harmonisation [ICH] Guidance E2A 1995).  
At each study visit, subjects will be questioned in a general way to ascertain if AEs have 
occurred since the previous visit (e.g., “Have you had any health problems since the previous 
visit/you were last asked?”).  All AEs are collected from the time the informed consent is signed 
until the end of the follow-up period.  This includes events occurring during the screening period 
of the study, regardless of whether or not investigational product is administered.  Where 
possible, a diagnosis rather than a list of symptoms should be recorded.  If a diagnosis has not 
been made, then each symptom should be listed individually.  All AEs should be captured on the 
appropriate AE pages in the eCRF and in source documents.  In addition to untoward AEs, 
unexpected benefits outside the investigational product indication should also be captured on the 
AE eCRF. 
All AEs must be followed to closure, regardless of whether the subject is still participating in the 
study.  Closure indicates that an outcome is reached (AE has resolved), stabilization achieved 
(the investigator does not expect any further improvement or worsening of the event), or the 
event is otherwise explained.  When appropriate, medical tests and examinations are performed 
so that resolution of event(s) can be documented. 
8.1.1 
Severity Categorization 
The severity of AEs must be recorded during the course of the event including the start and stop 
dates for each change in severity.  Any changes in the severity of the AE must be recorded. 
The medical assessment of severity is determined by using the following definitions: 
Mild:  A type of AE that is usually transient and may require only minimal treatment or 
therapeutic intervention.  The event does not generally interfere with usual activities of daily 
living. 
Moderate:  A type of AE that is usually alleviated with specific therapeutic intervention.  The 
event interferes with usual activities of daily living, causing discomfort but poses no significant 
or permanent risk of harm to the research subject. 
Severe:  A type of AE that interrupts usual activities of daily living, or significantly affects 
clinical status, or may require intensive therapeutic intervention.

Page 74 of 131 
8.1.2 
Causality Categorization 
The investigator will assess causal relationship between the investigational product and each AE 
(i.e, their relationship to study drug), and answer “yes” or “no” to the question, “Do you consider 
that there is a reasonable possibility that the event may have been caused by the investigational 
product?”  
8.1.3 
Variables 
The following variables will be collected for each AE: 
 AE  
 The date when the AE started and stopped 
 Maximum intensity or intensity or changes in intensity 
 Whether the AE is serious or not 
 Investigator causality rating against the study drug (yes or no) 
 Action taken with regard to investigational product (none, dose reduced, interrupted, 
withdrawn)  
 AE caused subject’s discontinuation from study (yes or no) 
 Outcome (fatal, not recovered/not resolved, recovered/resolved with sequelae, 
recovering/resolving, recovered/resolved, unknown) 
 
8.1.4 
Symptoms of the Disease Under Study 
Symptoms of the disease under study (e.g., depression) should not be classified as AEs as long as 
they are within the normal day-to-day fluctuation or expected progression of the disease and are 
part of the efficacy data to be collected in the study; however, significant worsening of the 
symptoms should be recorded as an AE. 
8.1.5 
Adverse Events Based on Clinical Laboratory and Other Safety Evaluations 
A change in the value of a clinical laboratory, vital sign, or ECG assessment can represent an AE 
if the change is clinically relevant or if, during treatment with the investigational product, a shift 
of a parameter is observed from a normal value to an abnormal value, or a there is a further 
worsening of an already abnormal value.  When evaluating such changes, the extent of deviation 
from the reference range, the duration until return to the reference range, either while continuing 
treatment or after the end of treatment with the investigational product, and the range of variation 
of the respective parameter within its reference range, must be taken into consideration. 
If, at the end of the treatment period, there are abnormal clinical laboratory, vital sign, or ECG 
values which were not present at the pretreatment value observed closest to the start of study 
treatment, further investigations should be performed until the values return to within the 
reference range or until a plausible explanation (e.g., concomitant disease) is found for the 
abnormal values.

Page 75 of 131 
The investigator should decide, based on the above criteria and the clinical condition of a 
subject, whether a change in a clinical laboratory, vital sign, or ECG parameter is clinically 
significant and therefore represents an AE. 
8.1.6 
Adverse Events Based on Signs and Symptoms 
All AEs spontaneously reported by the subject or reported in response to the open question from 
the study personnel: “Have you had any health problems since the previous visit/you were last 
asked?” or revealed by observation, will be collected and recorded in the eCRF. 
8.1.7 
Pregnancy 
All pregnancies are to be reported from the time informed consent is signed until the end of the 
follow-up period. 
Any report of pregnancy for any study participant must be reported within 24 hours to Marinus 
Safety Department or its delegate using the Pregnancy Report Form (and any applicable 
follow-up reports).  The study participant must be withdrawn. 
Every effort should be made to gather information regarding the pregnancy outcome and 
condition of the infant.  It is the responsibility of the investigator to obtain this information 
within 30 calendar days after the initial notification and approximately 30 calendar days 
postpartum.  
Pregnancy complications such as spontaneous abortion/miscarriage or congenital abnormality 
are considered SAEs and must be reported using the Marinus Serious Adverse Event Form.  
Note:  An elective abortion is not considered an SAE. 
In addition to the above, if the investigator determines that the pregnancy meets serious criteria, 
it must be reported as an SAE using the Marinus Serious Adverse Event Form to Marinus Safety 
Department.  The test date of the first positive serum/urine -HCG test or ultrasound result will 
determine the pregnancy onset date.

Reference Safety Information 
The reference for safety information for this study is the Investigator’s Brochure (IB), which the 
sponsor has provided under separate cover to all investigators. 
8.2.2 
Reporting Procedures 
All initial and follow-up SAE reports must be reported by the investigator to Marinus Safety 
Department within 24 hours of the first awareness of the event.  
The investigator must complete, sign, and date the Marinus Serious Adverse Event Forms and 
verify the accuracy of the information recorded on the form with the corresponding source 
documents and fax or e-mail the form to:

Note:  The 24-hour reporting requirement for SAEs does not apply to reports of abuse, misuse, 
overdose, or medication errors unless they result in an SAE.  
8.2.3 
Serious Adverse Event Definition 
An SAE is any untoward medical occurrence (whether considered to be related to investigational 
product or not) that at any dose: 
 Results in death 
 Is life-threatening.  Note:  The term “life-threatening” in the definition of “serious” refers to 
an event in which the subject was at risk of death at the time of the event; it does not refer to 
an event that hypothetically might have caused death if it was more severe. 
 Requires inpatient hospitalization or prolongation of existing hospitalization.  Note:  
Hospitalizations, which are the result of elective or previously scheduled surgery for 
pre-existing conditions, which have not worsened after initiation of treatment, should not be 
classified as SAEs.  For example, an admission for a previously scheduled ventral hernia 
repair would not be classified as an SAE; however, complication(s) resulting from a 
hospitalization for an elective or previously scheduled surgery that meet(s) serious criteria 
must be reported as an SAE(s). 
 Results in persistent or significant disability/incapacity. 
 Is a congenital abnormality or birth defect.  
 Is an important medical event.  
Note:  Important medical events that may not result in death, be life-threatening, or require 
hospitalization may be considered an SAE when, based on appropriate medical judgment, 
they may jeopardize the subject and may require medical or surgical intervention to prevent 
one of the outcomes listed in this definition.  Examples of such medical events include 
allergic bronchospasm requiring intensive treatment in an emergency room or at home; blood 
dyscrasias or convulsions that do not result in inpatient hospitalization; or the development of 
drug dependency or drug abuse.  
8.2.4 
Serious Adverse Event Collection Time Frame 
All SAEs (regardless of relationship to study) are collected from the time the subject signs the 
informed consent until the end of the follow-up period and must be reported to the Marinus 
Safety Department or its delegate within 24 hours of the first awareness of the event.  In 
addition, the Marinus medical monitor should be informed of the event within 24 hours via either 
email or a phone call.  
In addition, any SAE(s) considered “related” to the investigational product and discovered by the 
investigator at any interval after the study has completed must be reported to the Marinus Safety 
Department within 24 hours of the first awareness of the event.

8.2.5 
Serious Adverse Event Onset and Resolution Dates 
The onset date of the SAE is defined as the date the event meets serious criteria.  The resolution 
date is the date the event no longer meets serious criteria, the date the symptoms resolve, or the 
date the event is considered chronic.  In the case of hospitalizations, the hospital admission and 
IV dates are considered the onset and resolution dates, respectively. 
In addition, any signs or symptoms experienced by the subject after signing the informed consent 
form or leading up to the onset date of the SAE, or following the resolution date of the SAE, 
must be recorded as an AE, if appropriate. 
8.2.6 
Fatal Outcome 
Any SAE that results in the subject’s death (i.e. the SAE was noted as the primary cause of 
death) must have fatal checked as an outcome with the date of death recorded as the resolution 
date.  For all other events ongoing at the time of death that did not contribute to the subject’s 
death, the outcome should be considered not resolved, without a resolution date recorded. 
For any SAE that results in the subject’s death or any ongoing events at the time of death, unless 
another investigational product action was previously taken (e.g., drug interrupted, reduced, 
withdrawn), the action taken with the investigational product should be recorded as “dose not 
changed” or “not applicable” (if the subject never received the investigational product).  The 
investigational product action of “withdrawn” should not be selected solely as a result of the 
subject’s death.  
8.2.7 
Regulatory Agency, Institutional Review Board, Ethics Committee, and Site 
Reporting 
The sponsor or its delegate is responsible for notifying the relevant regulatory authorities of 
related, unexpected SAEs. 
In addition, the sponsor or its delegate is responsible for notifying active sites of all related, 
unexpected SAEs occurring during all interventional studies across the ganaxolone clinical 
development program.  
The investigator is responsible for notifying the local Institutional Review Board (IRB), local 
Ethics Committee (EC), or the relevant local regulatory authority of all SAEs that occur at his or 
her site as required.

9.1 
Data Collection 
The investigators’ authorized site personnel must enter the information required by the protocol 
on the eCRFs.  A study monitor will visit each site in accordance with the monitoring plan and 
review the eCRF data against the source data for completeness and accuracy.  Discrepancies 
between source data and data entered on the eCRF will be addressed by qualified site personnel.  
When a data discrepancy warrants correction, the correction will be made by authorized site 
personnel.  Data collection procedures will be discussed with the site at the site initiation visit 
and/or at the investigator’s meeting.  Once a subject is enrolled, it is expected that site personnel 
will complete the eCRF entry within approximately 2 business days of the subject’s visit.   
9.2 
Clinical Data Management 
Data are to be entered into a clinical database as specified in the eCRF completion guidelines or 
data management plan.  Quality control and data validation procedures are applied to ensure the 
validity and accuracy of the clinical database. 
Data are to be reviewed and checked for omissions, errors, and values requiring further 
clarification using computerized and manual procedures.  Data queries requiring clarification are 
to be communicated to the site for resolution.  Only authorized personnel will make corrections 
to the clinical database, and all corrections are documented in an auditable manner. 
9.3 
Statistical Analysis Plan 
The SAP will provide the statistical methods and definitions for the analysis of the safety and 
efficacy data, and it will describe the approaches to be taken for summarizing other study 
information such as subject disposition, demographics and baseline characteristics, 
investigational product exposure, and prior and concomitant medications.  The SAP will also 
include a description of how missing data will be addressed.  
The SAP will be finalized prior to database lock and/or unblinding of any portion of the trial to 
preserve the integrity of the statistical analysis and study conclusions.  
9.3.1 
Data Review Committee (DRC) and Recommendations for Dosing  
Adverse events and other safety data, including sedation and dosing changes, will be adjudicated 
by the DRC before proceeding to the double-blind part of the study.  The dose recommendation 
will be made by a DRC comprised of the Marinus Chief Medical Officer and 2 external 
physicians and potentially other experts familiar with the clinical care of women with major 
depression or PPD and with experience in conducting clinical trials. The DRC may also consult 
other experts, such as a statistician and a pharmacokineticist.  A separate guidance document will 
outline the functions and membership of the DRC. 
After completion of the double-blind part, the data will be evaluated by an independent DRC.  
Based on the analysis and recommendation by the DRC, the study may be closed at that point, or

an additional approximately 50 women with PPD will be treated with ganaxolone or placebo 
under a similar study design but using a different dosing regimen.  The daily dose may be 
lowered, increased, or the previous dosing may be repeated.  However, the total daily dose will 
not exceed 1,200 mg and no single dose will be higher than 675 mg. 
Marinus may decide to stop the study, or make the data public at any time during the open-label 
portion of the trial or after completion of the double-blind part of the study. 
9.3.2 
Justification for Sample Size 
With a sample size of 50 subjects/group, the DBPC part of the trial will be able to detect a 
medium effect size (per Cohen’s d) with 93% power using a two-sided significance level of 0.05. 
9.3.3 
Study Population 
The Screened Set will consist of all subjects who have signed an informed consent. 
The Randomized Set will consist of subjects randomized in the DBPC part of the trial.  
The Safety Set will consist of all subjects who received IV IP.  
The modified Intent to Treat Set (mITT) will consist of all subjects in the DBPC part of the 
trial who received IP and who have at least 1 post-baseline HAMD17 assessment.  The mITT set 
will be the primary efficacy population for the DBPC part of the trial.  
The Per-Protocol Set will consist of all subjects in the mITT set who do not have major protocol 
deviations that may affect key efficacy endpoints.  
9.4 
Analysis Methods 
Data will be presented by study part (OL, DBPC), dosing or treatment group within study part 
and, if applicable, study visit. Continuous variables will be summarized as numbers of 
observations, means, measures of variance (e.g., standard deviation), and percentiles (e.g., 
median, minimum, maximum).  Categorical variables will be summarized as numbers of 
observations and percentages. 
9.4.1 
Demographic and Baseline Characteristics 
Baseline characteristics will include a summary of the following: 
 Subject demographics 
 Pre-existing medical conditions 
 Prior therapies 
 Medical history

9.4.2 
Subject Disposition 
Frequencies and percentages of subjects who discontinued the study and reasons for 
discontinuation will be summarized. 
9.4.3 
Investigational Medicinal Product 
Overall exposure to investigational product, such as duration of exposure, as well as dose 
adjustments (i.e., deviations from the scheduled titration scheme) will be summarized. 
9.4.4 
Concomitant Medication 
Concomitant medications will be coded using the World Health Organization Drug Dictionary 
(WHO-DD) and will be summarized by drug class and preferred drug name. 
9.4.5 
Safety Analyses 
Reported AEs terms will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA).  The incidence of treatment emergent AEs (TEAEs), defined as AEs that started or 
worsened after first administration of IP, will be summarized by system organ class and 
preferred term. Separate summaries of TEAEs by severity and relatedness will be done.  SAEs 
and TEAEs leading to discontinuation of the study drug will also be summarized separately.  
The absolute values and change from baseline in laboratory tests, vital signs, SSS, ECG 
parameters, and CSSRS will be summarized.  
Results of physical examinations will be listed.  
9.4.6 
Efficacy Analyses 
Efficacy parameters will be summarized for both the open-label and DBPC parts but will be 
analyzed only for the DBPC part.  For the open-label part, referring to efficacy endpoints as 
“primary,” “secondary,” and “exploratory” is related to the degree of influence each type of 
endpoint is expected to have on decision-making rather than to considerations associated with 
inferential analysis (such as control of type 1 error). The primary time point of interest for all 
efficacy parameters will be Day 10 for the DBPC part and the visit at end of treatment (before 
initiation of taper) for the open-label part. 
9.4.6.1 
Primary Endpoint 
The primary efficacy endpoint will be HAMD17 total score change from baseline; this will be 
assessed at Day 10 for the DBPC part and at the visit at end of treatment for the open-label part. 
The primary efficacy analysis will be done using the mITT set (DBPC part only). The analytical 
method will be mixed model repeated measures (MMRM) with baseline HAMD17 total score as 
a covariate. Significance will be tested at a two-sided 0.05 level. Unstructured covariance will be 
specified although alternative covariance structures may be used, if appropriate, to achieve 
convergence or greater efficiency. Sensitivity analysis will be used to evaluate the assumption of 
data missing at random (MAR), if applicable.

Statistical Methods 
Efficacy pai·ameters will be sUilllnai·ized for open-label and DBPC paiis. Observed values and 
changes from baseline for HAMD 17, EPDS, and STAI6 total scores, subscales, and individual 
items will be smnmai·ized by visit. The categorical outcomes of HAMD 17 response, HAMD 17 
remission, and CGI-I will be sUilllnarized by visit. 
For the DBPC paii, the prefen ed approach for analyses of ti·eatinent group differences in 
secondaiy and explorato1y continuous efficacy vai·iables will be MMRM but other approaches 
such as t-tests, analysis of covai·iance, or non-parameti·ic methods may be used if necessa1y or 
more practical. Similarly, the prefen ed approach for analysis of secondaiy and explorato1y

categorical efficacy variables will be repeated measures (e.g., generalized estimating equations) 
but other approaches such as chi square or Fisher’s exact tests may be used. 
 
9.4.7 
Other Analyses 
No other analyses are planned in this study. 
9.4.8 
Handling of Missing and Incomplete Data 
While every attempt must be made by the investigator to provide complete data, there are cases 
in which this may not always be possible (e.g., incomplete subject recall of start and stop dates).  
Unrecorded values will be treated as missing, except for severity and relationship to 
investigational medicinal product for AEs.  If the severity or relationship to investigational 
medicinal product is missing for an AE, which occurred post administration of investigational 
medicinal product, the event will be regarded as severe and related to investigational medicinal 
product, respectively. 
After completion of the study, a set of sensitivity analyses will be conducted to evaluate the 
impact of missing data on the results.  The methodologies for the addressing missing data will be 
specified in the Statistical Analysis Plan (SAP).   
9.4.9 
Pharmacokinetic Analyses 
Five samples of blood will be collected to determine ganaxolone plasma concentrations during 
the study.  Samples will be collected on 3 occasions during treatment with ganaxolone to 
determine trough concentrations in plasma.  An additional 2 samples of blood will be collected at 
follow up visits, after ganaxolone treatment has been completed, to monitor the disappearance of 
ganaxolone following cessation of treatment.

It is the investigator’s responsibility to ensure that adequate time and appropriately trained 
personnel are available at the site prior to commitment to participate in this study.  The 
investigator should also be able to estimate or demonstrate a potential for recruiting the required 
number of suitable subjects within the agreed recruitment period. 
The primary diagnosis and eligibility for the trial are assessed by a qualified licensed physician 
investigator (or his/her delegate) at the study site. The physician at the study site will be 
accountable for clinical assessments, physical examinations, and medication administration 
(including deciding whether the dose is escalated or not). The remote SAFER interview will be 
conducted to confirm the diagnosis of PPD and eligibility for the trial from the depression 
severity point of view.  
The investigator will maintain a list of appropriately qualified persons to whom the investigator 
has delegated significant study-related tasks, and shall, upon request of the sponsor, provide 
documented evidence of any licenses and certifications necessary to demonstrate such 
qualification.  Curriculum vitae for investigators and sub-investigators are provided to the study 
sponsor (or designee) before starting the study. 
If a potential research subject has a primary care physician, the investigator should, with the 
subject’s consent, inform them of the subject’s participation in the study. 
10.2.2 
Protocol Adherence and Investigator Agreement 
The investigator and any co-investigators must adhere to the protocol as detailed in this 
document.  The investigator is responsible for enrolling only those subjects who have met 
protocol eligibility criteria.  Investigators are required to sign an investigator agreement to 
confirm acceptance and willingness to comply with the study protocol. If the investigator 
suspends or terminates the study at their site, the investigator will promptly inform the sponsor 
and the IRB/EC and provide them with a detailed written explanation.  The investigator will also 
return all investigational product, containers, and other study materials to the sponsor.  Upon 
study completion, the investigator will provide the sponsor, IRB/EC, and regulatory agency with 
final reports and summaries as required by (inter)national regulations. 
Communication with local IRBs/ECs, to ensure accurate and timely information is provided at 
all phases during the study, may be done by the sponsor, applicable CRO, investigator, or for 
multicenter studies, the coordinating principal investigator according to national provisions and 
will be documented in the investigator agreement. 
10.2.3

Page 85 of 131 
observations and other data pertinent to the clinical investigation.  Electronic case report forms 
must be completed by the investigator or designee as stated in the site delegation log. 
All data will have separate source documentation; no data will be recorded directly onto the 
eCRF.  All data sent to the sponsor must be endorsed by the investigator. 
The clinical research associate (CRA)/study monitor will verify the contents against the source 
data per the monitoring plan.  If the data are unclear or contradictory, queries are sent for 
corrections or verification of data. 
10.2.3.2 
Recording, Access, and Retention of Source Data and Study Documents 
Original source data to be reviewed during this study will include, but are not limited to: 
subject’s medical file, including past psychiatric history.  
The investigator must permit authorized representatives of the sponsor, the IRB/EC, and auditors 
to inspect facilities and to have direct access to original source records relevant to this study, 
regardless of media. 
The CRA/study monitor will check the eCRF entries against the source documents.  The consent 
form includes a statement by which the subject agrees to the monitor/auditor from the sponsor or 
its representatives, national or local regulatory authorities, or the IRB/EC, having access to 
source data (e.g., subject’s medical file, appointment books, original laboratory reports, X-rays 
etc.).  
These records must be made available within reasonable times for inspection and duplication, if 
required, by a properly authorized representative of any regulatory agency (e.g., the US FDA) or 
an auditor. 
Essential documents must be maintained according to ICH GCP requirements and may not be 
destroyed without written permission from the sponsor. 
10.2.3.3 
Audit/Inspection 
To ensure compliance with relevant regulations, data generated by this study must be available 
for inspection upon request by representatives of, for example, the US FDA (as well as other US 
national and local regulatory authorities), the European Medicines Agency (EMA), the 
Medicines and Healthcare Products Regulatory Agency, other regulatory authorities, the sponsor 
or its representatives, and the IRB/EC for each site. 
10.2.3.4 
Financial Disclosure 
The investigator is required to disclose any financial arrangement during the study and for 1 year 
after, whereby the outcome of the study could be influenced by the value of the compensation for 
conducting the study, or other payments the investigator received from the sponsor.  The 
following information is collected:  any significant payments from the sponsor or subsidiaries 
such as a grant to fund ongoing research, compensation in the form of equipment, retainer for

ongoing consultation or honoraria; any proprietary interest in investigational product; any 
significant equity interest in the sponsor or subsidiaries as defined in 21 CFR 54 2(b) (1998). 
10.3 Ethical Considerations 
10.3.1 
Informed Consent 
It is the responsibility of the investigator to obtain written informed consent from all study 
subjects prior to any study-related procedures including screening assessments.  All consent 
documentation must be in accordance with applicable regulations and GCP.  Each subject is 
requested to sign and date the subject informed consent form or a certified translation if 
applicable, after the subject has received and read the written subject information and received 
an explanation of what the study involves, including but not limited to:  the objectives, potential 
benefits and risk, inconveniences, and the subject’s rights and responsibilities.  A copy of the 
informed consent documentation (i.e, a complete set of subject information sheets and fully 
executed signature pages) must be given to the subject.  This document may require translation 
into the local language.  Signed consent forms must remain in each subject’s study file and must 
be available for verification at any time. 
If local IRB/EC is used, the principal investigator provides the sponsor or its delegate with a 
copy of the consent that was reviewed by the IRB/EC and received their favorable 
opinion/approval.  A copy of the IRB/EC’s written favorable opinion/approval of these 
documents must be provided to the sponsor prior to the start of the study unless it is agreed to 
and documented prior to study start that another party (i.e, CRO or coordinating principal 
investigator) is responsible for this action.  Additionally, if the IRB/EC requires modification of 
the sample subject information and consent document provided by the sponsor, the 
documentation supporting this requirement must be provided to the sponsor or delegate. 
10.3.2 
Institutional Review Board or Ethics Committee 
Responsibility for coordinating with IRBs/ECs is defined in the investigator agreement. 
Prior to implementing changes in the study, the sponsor and the IRB/EC must approve any 
revisions of all informed consent documents and amendments to the protocol unless there is a 
subject safety issue. 
Investigational product supplies will not be released until the sponsor or its delegate has received 
written IRB/EC approval of and copies of revised documents. 
The investigator is responsible for keeping the IRB/EC apprised of the progress of the study and 
of any changes made to the protocol, but in any case, at least once a year.  The investigator must 
also keep the local IRB/EC informed of any serious and significant AEs.

10.4 Privacy and Confidentiality 
All sites and laboratories or entities providing support for this study, must, where applicable, 
comply with the Health Insurance Portability and Accountability Act (HIPAA) act of 1996.  A 
site that is not a covered entity as defined by HIPAA must provide documentation of this fact to 
the sponsor or its delegate. 
The confidentiality of records that may be able to identify subjects will be protected in 
accordance with applicable laws, regulations, and guidelines. 
After subjects have consented to take part in the study, the sponsor and/or its representatives may 
review their medical records and data collected during the study.  These records and data may, in 
addition, be reviewed by others including the following:  independent auditors who validate the 
data on behalf of the sponsor; national or local regulatory authorities; and the IRB/EC which 
gave approval for the study to proceed.  The sponsor and/or its representatives accessing the 
records and data will take all reasonable precautions in accordance with applicable laws, 
regulations, and guidelines to maintain the confidentiality of subjects’ identities. 
Subjects are assigned a unique identifying number; however, their initials and date of birth may 
also be collected and used to assist the sponsor in verifying the accuracy of the data (e.g., to 
confirm that laboratory results have been assigned to the correct subject).  
The results of studies - containing subjects’ unique identifying number, relevant medical records, 
and possibly initials and dates of birth – will be recorded.  They may be transferred to, and used 
in, other countries which may not afford the same level of protection that applies within the 
countries where this study is conducted.  The purpose of any such transfer would include:  to 
support regulatory submissions, to conduct new data analyses to publish or present the study 
results, or to answer questions asked by regulatory or health authorities. 
10.5 Study Results and Publication Policy 
Marinus will endeavor to publish the results of all qualifying, applicable, and covered studies 
according to external guidelines in a timely manner regardless of whether the outcomes are 
perceived as positive, neutral, or negative.  
The term “publication” refers to any public disclosure including original research articles, review 
articles, oral presentations, abstracts and posters at medical congresses, journal supplements, 
letters to the editor, public presentations to the investors in the company, invited lectures, 
opinion pieces, book chapters, electronic postings on medical/scientific or company website, or 
other disclosure of the study results, in printed, electronic, oral or other form.  The results may be 
made public after completion of either the open-label part or double-blind part.

Study Synopsis 
 
Design:  
This is a Phase 2, multicenter study in women with 
postpartum depression (PPD) consisting of 2 parts:  Open 
Label Part: multiple ascending dose open-label focused on 
safety and tolerability in 5 groups that differ by total daily 
dosing and formulation of study drug; and Double-blind 
Part is a double-blind placebo-controlled (DBPC) focused on 
safety, tolerability and efficacy in one group.  The Double-
blind Part will begin after the Open Label Part dosing is 
completed. The dosing, treatment duration and timing of 
evaluations for the double-blind portion of the study will be 
decided based on the results of the Open Label Part and 
recommendations of the Data Review Committee (DRC).  
The DRC is comprised of Marinus’ Chief Medical Officer 
and 2 external physician experts.   
Figures 1A and 1B depict the design for each subject group 
in the Open Label and Double-blind Parts, respectively.

be enrolled and dosing completed before proceeding to the 
double-blind group.  The goal of the open-label group is to 
explore the safety of oral ganaxolone in this population and 
identify a dosing regimen for the double-blind phase.    
For the open-label safety group approximately 48 women 18 
to 48 years of age with PPD will be screened to enroll 
approximately 24 patients.  During this open-label safety 
phase, for the first approximately 8 patients, ganaxolone will 
be titrated to a daily dose of 900 mg/day over 10 days, 
followed by a taper over 4 days.  This dosing group is called 
open-label 3 times daily (OL TID) group. For the next 
approximately 8 patients, ganaxolone will be administered at 
bedtime (QHS). For these patients ganaxolone will be 
titrated to a dose of 675 mg QHS over 4 days, which is then 
maintained until day 10, followed by a taper over 4 days. 
This dosing group is called OL QHS group. For the next 
approximately 8 patients of the open-label safety group, 
ganaxolone will be administered at a dose 675 mg QHS for 
28 days, followed by a taper over 4 days. This dosing group 
is called OL QHS 4-week dosing group. 
The investigator has the flexibility to adjust the dose if the 
patient experiences sedation, dizziness or other untoward 
effects in each dosing group. 
For the double-blind group, approximately 100 women with 
PPD 18 to 48 years of age will be screened to randomize 50 
women in a 1:1 ratio to receive ganaxolone or matching 
placebo for 14 days.  The dosing for the double-blind portion 
of the study will be decided based on the results of the open-
label portion and recommendations of the Data Review 
Committee (DRC).  The DRC is comprised of Marinus’ 
Chief Medical Officer and 2 external physician experts.  The 
total daily dose will not exceed 1200 mg.  Randomization 
will be stratified by the use of concomitant antidepressants 
so that the number of patients who are treated with 
antidepressants and who are not treated with antidepressants 
approximately 88 subjects.   
The first group (called OL TID) of approximately 8 subjects 
will receive oral ganaxolone (capsules) titrated to a daily 
dose of 900 mg/day over 10 days, followed by a taper over 4 
days.   
The second group (called OL QHS) of approximately 20 
subjects will receive oral ganaxolone (capsules) at bedtime 
(QHS), titrated to a dose of 675 mg QHS over 4 days, which 
is then maintained until day 10, followed by a taper over 4 
days.  
The third group (called OL QHS 4-week) of approximately 
20 subjects, oral ganaxolone (capsules) will be administered 
at a dose of 675 mg QHS for 28 days, followed by a taper 
over 4 days.  
The fourth group (called OL 1,125 mg group) of 
approximately 20 subjects will receive, on the first 2 days, 
oral ganaxolone capsules at a dose of 675 mg at 
approximately 7 pm (with dinner) and 675 mg at 10 pm; 
followed, by 26 days of ganaxolone 1,125 mg at dinner time; 
followed by a taper over 4 days. Approximately 6 subjects 
will participate in PK collection that requires an overnight 
stay on Day 1. 
The fifth group (called OL Bolus-Oral) of approximately 20 
subjects will receive ganaxolone starting with a single IV 
bolus 12 mg over 2 minutes at approximately 4 pm of Day 1; 
followed by ganaxolone oral suspension 750 mg at 6pm (with 
a fatty meal) and 750 mg at 10pm. On Day 2 subjects will 
receive ganaxolone oral suspension 750 mg at dinner time 
and 750 mg at bedtime, followed by 26 days of ganaxolone 
oral suspension 1,000 mg at dinner time, Treatment will be 
tapered over 4 days. Approximately 6 subjects will 
participate in PK collection that requires an overnight stay 
on Day 1.

Pharmacokinetics: For the OL TID and OL QHS groups, a total 
of 5 srunples of blood will be collected to dete1mine ganaxolone 
plasma concentrations during the study. Srunples will be 
collected on 3 occasions during treatment with ganaxolone to 
dete1mine trough concentrations in plasma. An additional 2 
samples of blood will be collected at follow up visits, after 
ganaxolone treatment has been completed, to monitor the 
disappearance of ganaxolone following cessation of treatment. 
For the OL QHS 4-week, OL 1,125 mg, and OL Bolus-oral 
groups, 6 samples of blood will be collected to determine 
ganaxolone plasma concentrations during the study. Samples 
will be collected on 4 occasions during treatment in the OL 
QHS 4 weeks group and on 5 occasions during treatment in the 
OL 1,125 mg and OL Bolus-oral groups to determine 
ganaxolone trough concentrations in plasma. Two additional 
samples of blood will be collected in the first 2 follow up visits 
in the OL QHS 4 weeks group and 1 additional sample will 
be collected in the OL 1,125 mg, and OL Bolus-oral groups 
at the first follow up visit after ganaxolone treatment has be.en 
completed, to monitor the disapperu·ance of ganaxolone 
following cessation of treatment. 
Statistical Methods: Data will be presented by study part

For the open-label safety group approximately 48 women 18 
to 48 years of age with PPD will be screened to enroll 
approximately 24 patients.  During this open-label safety 
phase, for the first approximately 8 patients, ganaxolone will 
be titrated to a daily dose of 900 mg/day over 10 days, 
followed by a taper over 4 days.  This dosing group is called 
OL TID group.  
For the next approximately 8 patients of the open-label 
safety group, ganaxolone will be administered at bedtime 
(QHS). For these patients ganaxolone will be titrated to a 
QHS dose of 675 mg over 4 days which is then maintained 
until day 10, followed by a taper over 4 days. This dosing 
group is called OL QHS group 
The investigator has the flexibility to adjust the dose amount 
and/or timing of dosing if the subject experiences untoward 
effects during the OL part, by reducing the dose first to a 
lower level and possibly increasing it back again later if 
tolerance to the untoward effects develops. 
 
The open-label safety part will be enrolled, and dosing 
completed before proceeding to the double-blind part.  The 
goal of the open-label part is to explore safety of IV and oral 
ganaxolone in this population and identify a dosing regimen 
for the double-blind part. 
 
Open-label Part 
For the open-label safety part, approximately 172 women 18 to 
48 years of age with PPD will be screened to enroll 
approximately 88 subjects.  
In the first group with approximately 8 subjects, ganaxolone 
will be titrated to a daily dose of 900 mg/day over 10 days, 
followed by a taper over 4 days.  This dosing group is called OL 
TID group.  
The second group with approximately 20 subjects will receive 
ganaxolone administered at bedtime (QHS). For these subjects, 
ganaxolone will be titrated to a QHS dose of 675 mg over 4 
days which is then maintained until day 10, followed by a taper 
over 4 days. This dosing group is called OL QHS group 
The third group with approximately 20 subjects will receive 
ganaxolone administered at a dose 675 mg QHS for 28 days, 
followed by a taper over 4 days. This dosing group is called OL

bedtime for a total of 1,512 mg on Day 1. On Day 2, subjects 
will receive ganaxolone oral suspension 750 mg at dinner 
time and 750 mg at bedtime, for a total of 1,500 mg, followed 
by 26 days of ganaxolone oral suspension 1,000 mg at dinner 
time, followed by a taper over 4 days. This dosing group is 
called OL Bolus-oral group

3.2.  Rationale for Study 
Design 
This study is intended to test whether ganaxolone is 
efficacious and safe in treatment of PPD.  
Various dose amounts, formulations, dosing schemes and 
treatment durations will be evaluated in the Open Label 
Part to inform the choice of the treatment scheme for the 
DBPC Part.  
Approximately 8 or 20 subjects, depending of the group, will 
receive open label ganaxolone to evaluate safety, tolerability, 
kinetics and efficacy of the drug in women diagnosed with 
PPD. Assessments of adverse events, laboratory and ECG, 
and clinical ratings for safety and efficacy will be gathered 
to evaluate the possible differential effect of the various 
dosing schemes.  
A double-blind evaluation of safety and efficacy will follow 
the completion of the open label groups.  This study part will 
utilize a randomized, parallel-group, placebo-controlled 
design in women diagnosed with PPD. Evaluations of safety 
and tolerability, as well as efficacy will utilize the same 
evaluation methods as in the open label part. The primary 
efficacy endpoint will be change from baseline in HAMD-17 
of active vs placebo treatments. The concomitant use of 
antidepressants or no use of antidepressants will be 
stratified 1:1 to enroll similar numbers of subjects in each

3.3.  Dose Selection 
Open-label QHS dosing group 
Approximately 8 patients will be allocated to the OL QHS 
group.  The enrollment for the OL QHS group will start after 
all patients allocated to the OL TID group have started their 
dosing.  
 
Open-label QHS 4-week dosing group 
Approximately 8 patients will be allocated to the OL QHS 4-
week dosing group.  The enrollment for the OL QHS 4-week 
group will start after all patients allocated to the OL QHS 
group have started their dosing.  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Open-label QHS dosing group 
Approximately 20 subjects will be allocated to the OL QHS 
group.  The enrollment for the OL QHS group will start after all 
subjects allocated to the OL TID group have started their 
dosing.  
 
Open-label QHS 4-week dosing group 
Approximately 20 subjects will be allocated to the OL QHS 4-
week dosing group.  The enrollment for the OL QHS 4-week 
group will start after all subjects allocated to the OL QHS group 
have started their dosing.  
 
Open-label 1,125 mg dosing group  
The OL 1,125 mg dosing group is included in the open-label 
part to explore whether administering ganaxolone orally at 
doses up to 1,125 mg per day over 4 weeks (including 1,350 
in the first 2 days) are safe and well-tolerated and show 
sustained effects, and whether the therapeutic effects are 
maintained over a 6-week follow-up period.  
The two evening 675 mg oral doses, within 3 hours of each 
other on Day 1 are expected to provide mean Cmax plasma 
concentrations of approximately 250-300 ng/mL, which may 
be mildly sedating. Day 2 twin evening dosing is expected to 
lead to similar exposure. In previous studies ganaxolone has 
been given up to a daily dose of 2000 mg, and at single doses 
of 1000 mg. Based on the previous experience this dose is 
expected to be safe.  
Approximately 20 subjects will be allocated to the OL 1,125 
mg dosing group.  The enrollment for the OL 1,125 mg 
group will start after all subjects allocated to the OL QHS 4-
week group have started their dosing.

The OL Bolus-Oral dosing group will explore whether 
administering ganaxolone IV bolus 12 mg followed by oral 
suspension dosing of up to 1,000 mg per day (including up to 
1,500 mg in the first 2 days) is safe and well-tolerated and 
shows sustained therapeutic effect over 4-weeks of dosing, 
and whether the therapeutic effects are maintained over a 6-
week follow-up period.  
This initial bolus infusion is targeted to provide a fast onset 
of antidepressant activity by delivery of rapid plasma 
exposures to ganaxolone. Together with the two evening 750 
mg oral doses, within 3 hours of each other, Day 1 dosing is 
expected to provide mean Cmax plasma concentrations of 
approximately 250-300 ng/mL, which may be mildly 
sedating. Day 2 twin evening dosing is expected to lead to 
similar exposure. In previous studies ganaxolone has been 
given up to a daily dose of 2,000 mg, and at single doses of 
1,000 mg. Based on the previous experience this dose is 
expected to be safe.  
 
Approximately 20 subjects will be allocated to the OL Bolus-
Oral dosing group.  The enrollment for the OL Bolus-Oral 
group will start after all subjects allocated to the OL 1,125 
mg group have started their dosing.  
Dose justification in context of previous experience with IV 
ganaxolone 
In Study 1042-0405, which was a Phase 1 study in healthy 
volunteers investigating the safety of IV ganaxolone, the 
highest bolus dose tested was 30 mg, which was infused over 
5-minutes (the same rate, 6 mg/min., as in the OL Bolus-
Oral group). This dose led to peak concentration levels 
(Cmax) of > 1,000 ng/mL with no safety concerns (except 
sedation).  This safety profile is consistent with findings from 
previous studies with the oral formulation of ganaxolone, in 
which Cmax levels of up to 200 to 300 ng/mL were commonly 
observed and were not associated with major safety findings 
or toxicity (apart from sedation-related effects).

Blinding Scheme 
Subjects will be randomized to ganaxolone or placebo in a 
1:1 ratio. The randomization scheme will be prepared by an 
independent third-party vendor. Treatment assignments will 
be obtained by the investigator (or designee) via an 
Interactive Voice and/or Web Response System (IxRS). The 
placebo infusion and placebo capsules are identical to the 
ganaxolone infusion and capsules, respectively, in their 
appearance.  An unblinded study pharmacist at the 
investigative site will prepare the ganaxolone and placebo IV 
solutions and allocate capsule supply for the double-blind 
part. Members of the DRC will be unblinded. All other 
study personnel, including persons involved in the 
evaluation of the study subjects (e.g. investigators, 
sub-investigators, and physicians/nurses), with the exception 
of the study pharmacist, will remain blinded at all times, 
except in case of an emergency.  Subjects will be blinded.   
 
Reason for Change:  Clarification of dose selection, update to number of subjects per treatment group and addition of 2 treatment groups and blinding scheme

3.4.  Study Duration 
For both the open-label safety OL TID and OL QHS groups, 
and the double-blind phase of the study the screening period 
will be up to 2 weeks, followed by a 14-day outpatient 
treatment period and a 14-day follow-up period. For the OL 
QHS 4-week dosing group the screening period will be up to 
2 weeks, followed by a 28-day outpatient treatment period, a 
4-day taper and a 3 month follow-up period.  
For both the open-label safety OL TID and OL QHS groups, and

During Open-label 
 
Adjusting dose and/or timings for the OL 1,125 mg dosing 
group 
The investigator has the flexibility to adjust dose by 
reducing the dose to 450 mg (2 capsules) at the second of 
Day 1 doses (at HS) and/or at either of Day 2 doses, and/or 
reduce to 900 mg, 675 mg, or 450 mg on Day 3 through Day 
28 (at dinner time) if subject experiences sedation, dizziness 
or other untoward effects during the OL part. The 
investigator can also change the timing of the evening dose 
bringing it closer to bedtime and taking it with a fatty snack 
instead of dinner. Any further adjustments as well as 
adjusted taper period doses should be discussed with the 
medical monitor. The investigator may increase the dose 
back to default levels if tolerance develops to the untoward 
effects.  
Adjusting dose and/or timings for the OL Bolus-Oral dosing 
group

7 – Study Procedures 
For the open-label safety group approximately 48 women 18 
to 48 years of age with PPD will be screened to enroll 
approximately 24 patients.  During this open-label safety 
phase, for the first approximately 8 subjects, ganaxolone will 
be titrated to a daily dose of 900 mg/day over 10 days, 
followed by a taper over 4 days.  This dosing group is called 
OL TID group.  
For the next approximately 8 subjects, ganaxolone will be 
administered at bedtime (QHS). For these subjects 
ganaxolone will be titrated to a QHS dose of 675 mg over 4 
days which is then maintained until day 10, followed by a 
taper over 4 days. This dosing group is called OL QHS 
group. 
For the next approximately 8 subjects, ganaxolone will be 
administered at bedtime (QHS). For these subjects 
ganaxolone treatment will be a QHS dose of 675 mg over 28 
days, followed by a taper over 4 days. This dosing group is 
called OL QHS 4-week group. 
The investigator has the flexibility to adjust the dose if the 
patient experiences sedation, dizziness or other untoward 
effects during the OL phase.  
 
 
 
 
 
 
 
 
 
 
For the open-label safety part approximately 172 women 18 to 
48 years of age with PPD will be screened to enroll 
approximately 88 subjects.  During this open-label safety part, 
for the first approximately 8 subjects, ganaxolone will be titrated 
to a daily dose of 900 mg/day over 10 days, followed by a taper 
over 4 days.  This dosing group is called OL TID group.  
For the next approximately 20 subjects, ganaxolone will be 
administered at bedtime (QHS). For these subjects ganaxolone 
will be titrated to a QHS dose of 675 mg over 4 days which is 
then maintained until day 10, followed by a taper over 4 days. 
This dosing group is called OL QHS group. 
For the next approximately 20 subjects, ganaxolone will be 
administered at bedtime (QHS). For these subjects ganaxolone 
treatment will be a QHS dose of 675 mg over 28 days, followed 
by a taper over 4 days. This dosing group is called OL QHS 4-
week group. 
The next approximately 20 subjects of the open-label safety 
part will receive on the first 2 days ganaxolone capsules 675 
mg at dinner time and 675 mg at bedtime (for a total of 
1,350 mg per day on the first 2 days) followed by 26 days of 
ganaxolone capsules 1,125 mg at dinner time, followed by a 
taper over 4 days. This dosing group is called OL 1,125 mg 
group.  
For the next approximately 20 subjects of the open-label 
safety part, ganaxolone will be administered as IV bolus 12 
mg over 2 minutes at approximately 4 pm on Day 1 followed 
by ganaxolone oral suspension 750 mg at dinner time and 
750 mg at bedtime, for a total of 1,512 mg on the first day.

The open-label safety group will be enrolled, and dosing 
completed before proceeding to the double-blind group.  The 
goal of the open-label group is to explore safety of oral 
ganaxolone in this population and identify a dosing regimen 
for the double-blind phase.  
For the double-blind group, approximately 100 women with 
PPD 18 to 48 years of age will be screened to randomize 50 
women in a 1:1 ratio to receive ganaxolone or matching 
placebo for 14 days.  The dosing for the double-blind portion 
of the study will be decided based on the results of the open-
label portion and recommendations of the DRC.  The DRC 
is comprised of Marinus’ Chief Medical Officer and 2 
external physician experts.  The daily dose will not exceed

9.3.2 – Justification for 
Sample Size 
A sample size of 20 patients per group would be needed to 
detect a 3.5 point difference on the HAMD17 scale assuming 
standard deviation of 3.5 with power=86%, alpha=0.05, and 
2-sided t-test.  A sample size of 20 patients per group would 
be needed to detect a 5 point difference on the HAMD17 
scale assuming standard deviation of 3.5 with power=99%, 
alpha=0.05, and 2-sided t-test.  In a recent study by Hantsoo 
et al., (2014) sertraline was shown to be effective in 
treatment of PPD over 6 weeks of treatment (n=27; subset of 
women with strictly defined PPD).  The separation between 
sertraline and placebo was 7.8 points at the study end-point.  
Standard deviations were 2.8 and 3.9 for the placebo and 
sertraline groups, respectively. 
With a sample size of 50 subjects/group, the DBPC part of 
the trial will be able to detect a medium effect size (per 
Cohen’s d) with 93% power using a two-sided significance 
level of 0.05.

9.4.6 – Efficacy Analyses 
Approximately continuous endpoints (e.g, HAMD17, 
HAMD6, STAI6, and EPDS) will be analyzed by mixed 
model repeated measures (MMRM) analysis of covariance 
(ANCOVA) including all post-baseline treatment visits (but 
not the follow-up visits).  The model will include fixed 
effects of treatment, visit, treatment-by-visit interaction, and 
baseline value of the endpoint.  If at least 8 subjects are 
taking concomitant antidepressants during the study, it will 
also be included as a fixed effect.  An unstructured residual 
covariance matrix will be used; however alternate structures, 
Efficacy parameters will be summarized for both the OL 
and DBPC parts but will be analyzed only for the DBPC 
part.  For the OL part, referring to efficacy endpoints as 
“primary,” “secondary,” and “exploratory” is related to the 
degree of influence each type of endpoint is expected to have 
on decision-making rather than to considerations associated 
with inferential analysis (such as control of type 1 error).  
The primary time point of interest for all efficacy 
parameters will be Day 10 for the DBPC part and the visit at

to be specified in the SAP, will be used in the event of 
convergence issues.  Differences between the treatments 
overall and at each visit will be tested for statistical 
significance. 
Ordered categorical endpoints (CGI-I, EPDS obsessive 
thoughts - time occupied, EPDS obsessive thoughts – 
distress) will be analyzed at each visit by the Cochran-
Mantel-Haenszel (CMH) row mean scores test using rank 
scores.  Dichotomous categorical endpoints will be analyzed 
at each visit by Fisher's exact test [HAMD17 response (≥ 
50% decrease from Baseline), HAMD6 response (≥ 50% 
decrease from Baseline), HAMD17 remission (HAMD17 
total score ≤ 7].  However, if concomitant antidepressants 
are included in the model of approximately continuous 
endpoints, then the CMH row means scores test will control 
for their use, and the Fisher's exact test will be replaced with 
the CMH general association test, controlling for their use. 
Items related to sleep and anxiety within the HAMD17 and 
EPDS scales may be tabulated separately.   
After the completion of the double-blind phase and analysis 
of the data by the DRC Marinus may decide to enroll 
another group of subjects who are randomized to receive 
ganaxolone or placebo.  Since this is a Phase 2 study, no 
adjustments to the Type I error protections are considered

individual items will be summarized by visit.  The 
categorical outcomes of HAMD17 response, HAMD17 
remission, and CGI-I will be summarized by visit. 
For the DBPC part, the preferred approach for analyses of 
treatment group differences in secondary and exploratory 
continuous efficacy variables will be MMRM but other 
approaches such as t-tests, analysis of covariance, or non-
parametric methods may be used if necessary or more 
practical. Similarly, the preferred approach for analysis of 
secondary and exploratory categorical efficacy variables will 
be repeated measures (e.g., generalized estimating 
equations) but other approaches such as chi square or 
Fisher’s exact tests may be used.
