Brief summary:
The purpose of this study is to examine the safety and effectiveness of USL261 for the outpatient treatment of seizure clusters.

Detailed description:
Qualifying participants underwent an in-clinic administration (Test Dose Phase \[TDP\]) of two doses of USL261 (intranasal midazolam 5 mg), separated by 10 minutes, in the absence of seizures. Eligible participants were then randomized to USL261 versus Placebo in an outpatient Comparative Phase (CP). When the participant had a qualifying seizure cluster episode, as described in an individualized patient management plan, the participant's caregiver administered the double-blind dose. An open-label USL261 dose could be administered after 10 minutes and up to 6 hours after the double-blind dose, if the participant had persistent or recurrent seizures. Initial participants could not proceed to CP until an independent data safety monitoring board (DSMB) reviewed safety data from at least the first 25 participants in TDP; the DSMB performed additional safety reviews at pre-set intervals based on enrollment.

SYNOPSIS
Sponsor: Upsher-Smith Laboratories, Inc. (USL)
Name of Development Product:  USL261 (intranasal midazolam; formerly ITI-111)
Study Title: A Randomized, Double-Blind, Placebo-Controlled Study of the Safety and Efficacy of 
Intranasal Midazolam (USL261) in the Outpatient Treatment of Subjects with Seizure Clusters
Study Number: P261-401
Study Phase: III
Efficacy Objective(s):  
Primary Efficacy Objective: 
To evaluate the efficacy of USL261 compared with that of intranasal (IN) placebo for the outpatient 
treatment of seizure clusters based on Treatment Success, which is defined as achieving both of the 
following:

Termination of seizure(s) within 10 minutes after study drug administration, and

No recurrence of seizure(s) beginning 10 minutes after study drug administration to 6 hours
after study drug administration
Secondary Efficacy Objective(s):  
To evaluate the efficacy of USL261 compared with that of IN placebo for the outpatient treatment of 
seizure clusters using the following: 

Proportion of subjects with recurrence of  seizure(s) beginning 10 minutes after study drug
administration to 4 hours after study drug administration

Time to next seizure with a start time > 10 minutes after study drug administration
Safety Objective:
To evaluate the safety and tolerability of USL261 for the treatment of seizure clusters using the 
following assessments:

Adverse events (AEs)

Caregiver-recorded respiration rate at 15 minutes, 30 minutes, 1 hour, 2 hours and 4 hours after
study drug administration in the Comparative Phase

Clinical laboratory tests

Vital signs measurements (systolic and diastolic blood pressure, pulse rate, respiration rate and
temperature) as recorded by the study center personnel

Physical, nasal and neurological examinations

Brief Smell Identification Test (B-SIT)

Columbia-Suicide Severity Rating Scale (C-SSRS)

Requirement for unscheduled emergency room (ER) or emergency medical service (EMS) visit
within 24 hours after study drug administration
Study Design: 
This is a phase III multicenter study, with 2 distinct phases and 4 study center visits. The first phase is 
the Test-Dose Phase where subjects will receive 2 doses of open-label 5.0 mg USL261 administered 10 
minutes apart at the study center. The Test-Dose Phase is designed to assess the safety, tolerability, and 
pharmacokinetics (PK) of USL261 in a monitored setting and provide the caregivers with training on the 
study procedures. The Test-Dose Phase will be followed by the Comparative Phase, an outpatient, 
double-blind, placebo-controlled, parallel-group phase. In the Comparative Phase, all subjects will be 
randomized 2:1 to receive 5.0 mg USL261 or placebo. During the Comparative Phase, the subject’s 
caregiver will administer the double-blind study drug when the subject experiences a seizure cluster that 
meets the study criteria, as described in the subject’s individualized Patient Management Plan (PMP). If 
the treated seizure cluster has not terminated within 10 minutes after the initial drug administration, OR 
another seizure occurs between 10  minutes and 6 hours after administration of the study drug, AND the 
subject does not have < 8 breaths per minute, does not require emergency rescue treatment with assisted 
breathing or intubation and does not have excessive, uncharacteristic sedation (as defined by the 
investigator in the Patient Management Plan), the double-blind dose of study medication may be

followed by a single dose of 5.0 mg USL261. Any time between 24 to 120 hours after study drug 
administration, subjects and caregivers will return to the study center for a post-dose study visit. 
A maximum of approximately 350 subjects, aged 12 years or older, with a documented history of seizure 
clusters and on a stable antiepileptic drug (AED) regimen will be enrolled in the Test-Dose Phase. 
Before any subject continues to the Comparative Phase, safety data from at least 25 subjects in the Test-
Dose Phase will be reviewed by an independent Data and Safety Monitoring Board (DSMB). 
Enrollment will temporarily halt once approximately 25 subjects complete the Test-Dose Phase, to allow 
the DSMB to review the safety data. If the safety data from this initial cohort supports continuation of 
the trial according to the DSMB, enrollment into the Test-Dose Phase will resume and the initial 25 
subjects will proceed to the Comparative Phase. All subsequent subjects will progress directly from 
Test-Dose Phase to the Comparative Phase.

24. Subject has a positive pregnancy test
25. Subject has active suicidal plan/intent or suicidal thoughts as defined by a C-SSRS suicidal 
ideation score ≥ 3 or has had a suicide attempt since the last visit.
Study Population: A maximum of approximately 350 subjects enrolled in the Test-Dose Phase in order 
to achieve 240 subjects completing the Comparative Phase. This assumes that approximately 32% of 
subjects enrolled in the Test-Dose Phase do not complete the Comparative Phase.
Test/Reference Product, Dose, and Mode of Administration:
Test Product: USL261 (intranasal midazolam; formerly ITI-111)
Test-Dose Phase: Two (2) open-label 5.0 mg doses (1 actuation each), separated by 10 minutes (total 
dose 10 mg)
Comparative Phase: One (1) double-blind 5.0 mg dose (1 actuation); One (1) 5.0 mg dose (1 actuation) 
administered for persistent or recurrent seizure activity
Reference Product: Placebo nasal spray
Comparative Phase only: One (1) double-blind dose (1 actuation)
Duration of Treatment: 10 minutes for Test-Dose Phase, variable for Comparative Phase
Duration of Subject Participation:
Screening: Up to 28 days; can be longer during the time of DSMB review
Test-Dose Phase: Up to 28 days; can be longer during the time of DSMB review
Comparative Phase: The duration of each subject’s participation in the Comparative Phase will be 
variable and will be determined by the frequency of observed seizure events. Assuming an average of 3
seizure clusters per year, approximately half of the study subjects complete the study within ~4 months 
after randomization to treatment. Subjects may remain in the Comparative Phase for up to 6 months. 
Any subject who has not treated a seizure cluster meeting the study criteria within 6 months of Visit 3 
(Randomization) will be discontinued from the study.
Efficacy Assessment(s): 
Efficacy will be determined using the following information at a minimum:

Date and time of study drug administration

Date, start, and stop time of each seizure within 24 hours after any study drug administration 

Date and time when subject has returned to full baseline functionality after the treated seizure 
cluster, as determined by the caregiver
Safety Assessments:  
Collection of AEs, physical and neurological examinations, clinical laboratory evaluations, vital signs, 
caregiver-recorded respiration rate, 12-Lead ECG, pulse oximetry, sedation (determined by the OAA/S),
C-SSRS, the need for second dose of medication or emergency treatment, and B-SIT.
Pharmacokinetic Assessments: 
Blood samples will be collected before and at 5, 10, 20, 30 minutes and 1, 2, and 4 hours after 
administration of the first 5.0 mg test dose of USL261 at Visit 2. After 132 subjects have completed the 
Comparative Phase, for all new test dosed subjects, blood samples will be collected before and at 5, 10, 
20, 30 minutes and 1hour after administration of the first 5.0 mg test dose of USL261 at Visit 2.
Statistical Methods:
Efficacy
Efficacy variables will be analyzed using the modified Intent-to-Treat (mITT) Population, which 
consists of all subjects who are randomized to receive double-blind treatment, who receive at least 1 
dose of study drug during the Comparative Phase, and who have any post-treatment efficacy 
assessments.

Primary Efficacy Endpoint and Analysis:
The primary efficacy endpoint is the proportion of subjects who meet the criteria for Treatment Success. 
Treatment Success is a composite measure of efficacy that will be assessed based upon the first seizure 
cluster treated with study drug during the Comparative Phase. Treatment Success is defined as 
achieving the following:

Termination of seizure(s) within 10 minutes after administration of study drug and

No recurrence of seizure(s) beginning 10 minutes after administration of study drug to 6 hours
after administration of study drug
The primary efficacy endpoint will be analyzed by Fisher’s Exact Test. Chi-squared test will be 
performed as a sensitivity analysis.
The trial utilizes a group sequential design with 3 interim analyses and a maximum of approximately 
240 subjects who have completed the Comparative Phase.  Subjects who receive at least 1 dose of study 
drug during the Comparative Phase and who complete Visit 4 will have completed the Comparative 
Phase.  The interim analyses will occur at N=132, 165, and 204 subjects complete the Comparative 
Phase with a final analysis (if needed) at N=240 subjects completing the Comparative Phase.  At each 
interim analysis the trial may be stopped for efficacy or futility.  Interim analyses for efficacy are 
evaluated using a Lan-DeMets alpha spending function approximating the Pocock boundary to preserve 
type I error at 2.5%.  Futility monitoring is based on Bayesian predictive probabilities.  At each interim 
analysis the trial is stopped for futility if the predictive probability of success at the maximal sample size 
is less than 10%.  Assuming treatment rates of 0.40 for the placebo arm and Odds Ratio of 2.9, the 
power of this design is approximately 90%.  These analyses will be conducted using the mITT 
population and a one-sided test comparing two populations.  Interim analyses for efficacy and futility 
will be performed by an unblinded interim monitoring committee separate from the Sponsor.
Secondary Efficacy Endpoints and Analyses:
The secondary efficacy variables include the following:

Proportion of subjects with recurrence of a seizure(s) beginning 10 minutes after administration
of study drug to 4 hours after administration of study drug, by Fisher’s Exact Test. In addition,
Chi-squared test will be performed as a sensitivity analysis.

Time to next seizure with a start time > 10 minutes after study drug administration, analyzed by
a log-rank test, and presented with Kaplan-Meier estimates for time to event at specific
percentiles
Safety
Safety analyses will be performed using the Safety Population, which includes all subjects that receive at 
least 1 dose of study drug. Safety data from both the Test-Dose Phase and the Comparative Phase will be 
summarized. 
Safety Endpoints

Treatment Emergent Adverse Events (TEAEs) will be presented by treatment received, severity,
relationship to study drug and age group (< 18, ≥18 - <65 years, ≥65 years).

[u] Vital signs include blood pressure (BP), heart rate (HR), respiration rate (RR), and temperature. At Visit 2, BP, HR,
RR, and pulse oximetry are recorded before and at 5, 10, 15, 20, 30, 45 minutes and 1, 1.5, 2, 3 and 4 hours after the first
test dose. After 132 subjects have completed the Comparative Phase, for all new test dosed subjects, BP, HR, RR, and
pulse oximetry will be recorded before and at 5, 10, 15, 20, 30, 45 minutes and 1 hour after the first test dose. Temperature
will be measured only at the pre-dose time point.
[v] Caregiver counts the number of breaths taken by the subject during a 30-second interval. At Visit 2, caregivers will
measure respiration rate before and at 5, 10, 15, 20, 30, 45 minutes and 1, 1.5, 2, 3 and 4 hours after the first test dose.
After 132 subjects have completed the Comparative Phase, for all new test dosed subjects, caregivers will measure
respiration rate before and at 5, 10, 15, 20, 30, 45 minutes and 1 hour after the first test dose. On the day of treatment,
caregivers will measure respiration rate at approximately 15 and 30 minutes and 1, 2, and 4 hours after study drug
administration (see Section 6.2.2.3).
[w] Baseline/Screening version of the C-SSRS is administered at Visit 1. The Since Last Visit version is administered at
Visits 2, 3 and 4/ET.
[x] The study materials kit will include at a minimum: Individualized PMP, summary of the PMP, Subject Workbook
(used for collecting and recording seizure activity information, study drug administration, respiration rate, and other
observations made by the caregiver), study drug kit, and dosing instructions.
[y] Caregiver will evaluate the subject’s return to baseline functionality by recording the time when the subject was able
to return to what he/she was doing.

INTRODUCTION
1.1
Background Information
Acute repetitive seizures and seizure clusters occur in a subset of epilepsy patients. Seizure 
clusters have distinguishable characteristics that are easily recognized by patients, 
caregivers, and physicians and include a consistent onset (auras, prodrome) that may be 
indicative of convulsive or non-convulsive symptoms. Although patients typically recover 
between seizures, these seizure can last anywhere from minutes to hours.[1] When a cluster 
of seizures occurs outside a hospital, the patient must often be transported to an acute care 
facility so medical personnel can administer intravenous (IV) therapy to stop the 
seizure(s).[2]
Seizure clusters can evolve into prolonged seizures with worsening epileptogenesis if 
treatment is not prompt and effective.[3, 4] Furthermore, if left untreated, seizure clusters
may progress to status epilepticus, a life-threatening, prolonged epileptic crisis.[5] The 
primary goals of seizure cluster treatment are seizure cessation and prevention of seizure 
recurrence.[1] Acute benzodiazepine treatment is effective for seizure control and often 
results in rapid seizure cluster termination; however, most treatment options rely on 
intervention by emergency medical personnel and therefore delay treatment while the 
patient is transported to a medical facility.[6] The development of an easily administered 
outpatient treatment of seizure clusters may reduce emergency medical intervention and 
decrease seizure cluster duration. While rectal diazepam gel (Diastat®, Valeant 
Pharmaceuticals International) is currently available in the United States (US), a portion of 
the population does not respond adequately to this treatment, and/or for some, the rectal 
route of administration is inappropriate or unacceptable.[7] As such, a treatment that is 
effective in interrupting seizure activity, has a rapid onset of action, and is easily 
administered in the outpatient setting is currently an unmet medical need.
Midazolam is a benzodiazepine with potent inhibitory activity at the GABA-A receptor and 
demonstrates anticonvulsant properties.[8] In adults, midazolam is usually administered via 
IV or intramuscularly (IM) at doses of 1 mg to10 mg; pediatric patients are dosed by weight 
(mg/kg) and usually require higher doses than adults.[9] Like other benzodiazepines,
midazolam administration may cause sedation, anxiolysis, and amnesia.[10, 11] Sedative

effects usually occur within 5 minutes of IV administration and within 15 minutes of IM 
administration. Depending on the dose, route of administration, concurrent medications,
and patient’s age, peak sedation occurs within 30 to 60 minutes after dosing.[12]
Intranasal (IN) midazolam may be safe and effective for the rapid cessation of seizure 
activity in outpatient settings. Use of IN midazolam was originally described in the late 
1980s,[10] and over the past 15 years, approximately 20 publications have described it as a 
safe and efficacious treatment for seizure control in a variety of populations, including adult 
and pediatric.[7, 10, 13-31] Publications such as these demonstrate the desire of patients, 
caregivers, and physicians to have this type of product available for acute intermittent 
treatment of seizure clusters. Furthermore, use of IN midazolam for treatment of seizures 
has been advocated by numerous review articles and editorials.[32-35]
Much of the published work investigating the effects of IN midazolam on seizure control 
has used midazolam sterile injection solution (5 mg/mL) approved for IV delivery 
administered IN with a needleless syringe at doses ≤0.6 mg/kg. The delivery of IV-
approved midazolam sterile injection solution intranasally has not been optimized, nor is it 
approved by the Food and Drug Administration (FDA). In fact, the volume of midazolam 
sterile injection solution usually ranges from 1 ml-2 mL,[11] which exceeds the 
recommended volume for optimal IN delivery (≤200 μL).[34] Despite the sub-optimal 
formulation and delivery system, IN delivery of midazolam sterile injection solution has 
been very effective in some settings without major safety concerns; the most common 
adverse effects have been described as local nasal irritation and discomfort. Unpleasant 
taste was also commonly reported, suggesting possible oral ingestion of midazolam IV 
solution, perhaps caused by the suboptimal delivery volumes.[11]
Ikano Therapeutics Inc. (ITI, [previously Intranasal Therapeutics, Inc]) initiated 
development of a midazolam rescue treatment designed specifically for IN delivery (ITI-
111) for patients who require control of intermittent bouts of seizure activity, including
seizure clusters. In June 2010, Upsher-Smith Laboratories, Inc. (USL) obtained exclusive
global rights to ITI-111 (renamed as USL261) assuming all continued development, testing,
and clinical trials for the treatment of seizure clusters. The proprietary formulation of

USL261 delivers adequate drug concentrations in a small volume (100 μL), and preliminary 
human studies show positive pharmacokinetic (PK) and bioavailability properties with good 
safety and tolerability. The present study is designed to establish the efficacy and safety of 
USL261 for the outpatient treatment of seizure clusters.
1.2
Non-Clinical Information
To establish the safety, and to supplement the existing body of toxicology data for USL261, 
four nonclinical studies have been performed using USL261 administered IN (Table 2). 
These studies included a 14-day IN toxicology study in beagle dogs using the 
container/closure system (a unit dose spray pump) intended for clinical trials, a 14-day study 
in rats, a 90-day study in beagle dogs and a 6-month study in rats. All four studies were 
conducted in accordance with Good Laboratory Practice (GLP).

occurred shortly after dosing in most midazolam-treated groups, and these observations are 
consistent with the known pharmacological properties of midazolam.
No significant effects on the nasal cavity were observed, and the no-observable-adverse-
effect levels (NOAEL) were the maximum doses that could be administered based on 
midazolam solubility and the maximum volumes that could be ethically administered IN to 
the animals. The safety of systemic exposure of midazolam has been established via a 
complete set of animal studies as well as clinical experience with midazolam since its 
approval in 1985. A complete overview of the preclinical development and pharmacology 
of midazolam has previously been published.[36]
A 6-month IN study (including a 3-month interim sacrifice group) was conducted in rats 
(Experimur 10-160).  The dose levels and the experimental design were the same as in the 
14-day rat study (0, 1, 3, and 6 mg/day).  All effects noted were consistent with the 14-day
rat study, WIL-637002.  Gross necropsy revealed dose-related increases in liver weights
consistent with the known effects of chronic midazolam administration.  No other gross
lesions or significant findings were noted.  Histopathologic examination of the tissues
showed no remarkable changes in the nasal tissues or other tissues associated with twice
daily nasal administration. Intranasal instillation of Midazolam to Sprague-Dawley rats at
dose levels up to 6 mg/day for 6 months was considered well-tolerated.  Based on the lack
of histological changes observed in this study, the NOAEL (no-observed-adverse-effect
level) was considered to be 6 mg/day after 6 months of treatment.
In summary, intranasal dosing of high levels of midazolam at high multiples of the clinical 
doses resulted in no significant changes in any endpoints. Minor clinical signs observed were 
consistent with the known effects of midazolam by other approved routes of administration.

Results of Completed Studies
1.3.1.1
Study MZ0714
ITI conducted an initial phase I clinical trial (MZ0714) investigating the safety, 
bioavailability, PK, and pharmacodynamic (PD) properties of USL261 entitled “A single-
dose, open-label, five-way crossover, randomized, bioavailability and pharmacodynamic 
study comparing intranasal midazolam administration to intravenous midazolam 
administration in healthy human volunteers.” Safety, bioavailability, PK, and PD 
parameters for 3 doses of USL261 (2.5 mg, 5.0 mg, and 7.5 mg in 0.1 mL) were compared 
with administration of IV-approved midazolam sterile injection solution administered IV 
(2.5 mg in 5 mL) and IN (5.0 mg in 1 mL) via a needleless syringe.  
Results suggested that maximum plasma concentration (Cmax) of midazolam was achieved in 
all dose groups within 10 minutes to 15 minutes post-administration.  The Cmax for all doses 
of USL261 were within the range of those achieved following IV and IN administration of 
midazolam sterile injection solution.  USL261 demonstrated linear PK parameters.  The 
absolute bioavailability of all USL261 doses was higher (range:  62% – 73%) than 5.0 mg 
midazolam sterile injection solution administered intranasally (50%). 
Changes in PD measures were dependent on midazolam dose; subjects receiving the highest 
dose of USL261 (7.5 mg) reported the largest changes from baseline for all PD measures 
(Stanford Sleepiness Scale, Digit-Symbol Substitution Task, Observers Assessment of 
Alertness/Sedation [OAA/S]).  Route of administration (IV compared with IN) had a 
significant effect on the PD of midazolam.  For example, the maximal sedation effects for 
all IN midazolam formulations were observed between 45 minutes – 1 hour post-dose; 
however, maximal sedation occurred within 15 minutes in subjects administered IV 
midazolam.  It is important to note that no significant differences in PD parameters were 
reported between IN treatments. 
Overall, the proportion of subjects who experienced treatment-emergent adverse events 
(TEAEs) did not increase with ascending doses of IN midazolam.  No TEAEs were reported 
after administration of 2.5 mg IV midazolam.  All TEAEs were mild in intensity and the

majority of TEAEs (95.7%) were considered related to study drug.  No serious adverse 
events (SAEs) or deaths were reported, and no subject discontinued due to a TEAE.  
Overall, the most common drug-related TEAEs (reported by ≥10% of subjects) were 
increased nasal discomfort (84%), throat irritation (84%), increased lacrimation (76%), 
dysgeusia (72%), headache (20%), cough (12%), and rhinorrhea (12%).  These TEAEs were 
only observed when midazolam was administered intranasally (IV or IN formulations), 
which suggested that they were related to route of administration. 
1.3.1.2
Study MZ0815
A second phase I clinical trial (MZ0815) also investigated the safety, tolerability, PK, and 
PD characteristics of USL261 but in adult and adolescent epilepsy patients rather than 
healthy volunteers.  MZ0815 is a multicenter, in-patient study that evaluated an ascending 
single-dose and 2-dose administration of USL261 (2.5 mg, 5.0 mg, and 7.5 mg) given at 2 
study visits separated by ≥ 3 days.  USL261 was absorbed rapidly (approximately 13 
minutes to 20 minutes after a single dose; approximately 20 to 30 minutes after the 2-dose 
regimen) and the midazolam Cmax, area under the plasma concentration time curve from 
time 0 to time of last measurable concentration (AUC0-t), and area under the plasma 
concentration time curve from time 0 extrapolated to infinity (AUC0-∞) generally increased 
with total dose.  Midazolam Cmax was lower in adolescents as compared to adults. The mean 
t1/2 ranged from 2.75 to 4.39 hours.
USL261 was deemed safe when administered at doses of 2.5 mg to 15.0 mg (total dose) to 
adolescent and adult epilepsy patients who were taking concomitant AEDs.  Of the 90 
enrolled subjects, 88 (98%) experienced at least 1 TEAE.  No deaths or SAEs were reported, 
and no study subject prematurely discontinued due to intolerable AEs.  Most TEAEs were 
mild to moderate in intensity and deemed to be probably related to study drug.  The most 
frequently-reported TEAEs (reported by ≥10% of subjects) associated with study drug were 
dysgeusia (86%), oropharyngeal pain (57%), rhinalgia (31%), and burning sensation (11%).  
One subject, who was administered USL261 at a total dose of 12.5 mg, experienced 
moderate hypoxia approximately 90 minutes after administration of the second dose;

however, the event was transient and not associated with sedation, hypoventilation, or 
changes in vital signs.
1.3.1.3
Study P261-201
Study P261-201 was a single-center, in-patient trial investigating the safety, tolerability, PK, 
and PD of escalating single- and two-dose regimens of USL261 compared to placebo in 
adult subjects with epilepsy.  Subjects were assigned sequentially to 1 of 4 cohorts to 
receive either USL261 (10.0 mg, 15.0 mg, 17.5 mg, or 20.0 mg) or placebo at two dosing 
visits separated by ≥ 3 days.  Each subject received USL261 or placebo at Visit 2.  At Visit 
3, each subject received the same total dose as he/she received at Visit 2 administered as a 
divided dose.  
USL261 was absorbed rapidly (approximately 9 minutes to 19 minutes after a single dose; 
approximately 19 to 22 minutes after the two-dose regimen). Following either single dose or 
repeat dose administration, PK parameters for both MZ and 1-OH MZ were similar across 
cohorts and did not exhibit dose dependent changes. Exposure to MZ and 1-OH MZ (as 
indicated by Cmax and AUC parameters) was not dose proportional following single dose or 
repeat dose administration of 10.0 mg to 20.0 mg. Effects of USL261 on sedation and 
psychomotor performance were transient following single and repeat dose administration 
and were consistent across USL261 doses. Consistent with PK results, no dose response was 
observed in SSS or OAA/S Sum and Composite scores or their corresponding PD 
parameters from 10.0 to 20.0 mg USL261 following either single or repeat dose 
administration.
USL261 was generally safe and well-tolerated following single- or repeat-dose 
administration up to the maximum evaluated total dose level of 20 mg in adult subjects with 
epilepsy taking concomitant AEDs. In total, 58 subjects (96.7%) reported 179 TEAEs. All 
of the reported TEAEs were considered mild in severity with the majority (96.0%) were 
considered “probably related” to study drug. Treatment-emergent AEs reported in ≥20% of
subjects in any group were nasal discomfort and throat irritation, which occurred in 96% of
subjects administered MDZ NS. However, there was no clear dose relationship and these

events also occurred frequently in placebo subjects. Nasal mucosal disorder, headache,
dysgeusia, and hiccups were also common TEAEs, occurring in ≥10% MDZ NS subjects. 
1.3.1.4
Study P261-102
Study P261-102 was a single-center trial investigating the safety, tolerability, PK, and PD of 
single 2.5 mg and 5.0 mg doses of USL261 in generally healthy geriatric and non-geriatric 
subjects.  Enrollment was stratified into non-geriatric (18 – 40 years old, inclusive) and 
geriatric (≥ 65 years old) groups such that there were 12 subjects in the non-geriatric range 
and 18 subjects in the geriatric range.  Subjects were randomly assigned to receive single 
doses of both 2.5 mg and 5.0 mg USL261 in a 2x2 crossover fashion with a washout period 
of 4 – 10 days between dosing.  Mean systemic exposure (AUC) and peak plasma 
concentrations (Cmax) of MDZ were 20–45% higher in the geriatric subjects compared with 
nongeriatric subjects. Geriatric subjects exhibited greater cognitive effects than nongeriatric 
subjects, whereas maximum and overall sedation effects were comparable between the two 
groups.
Of the 30 enrolled subjects, 26 subjects (87%) reported at least one TEAE during the study 
with more geriatric subjects reporting a TEAE than younger subjects. All reported TEAEs 
(n=115) were considered mild in severity; most (91.3%) were considered “probably related” 
to the study drug. No SAEs or deaths were reported, and no subject discontinued study 
participation due to a TEAE. Although there were some differences between the 2.5 mg and 
5.0 mg doses with regard to the incidence of the more frequently reported AEs, there did not 
appear to be a consistent association with dose.

DESCRIPTION OF STUDY
3.1
Overview
This is a phase III multicenter study, with 2 distinct phases and 4 study center visits as 
depicted in Figure 1. The first phase is the Test-Dose Phase where subjects will receive 2
doses of open-label 5.0 mg USL261 administered 10 minutes apart at the study center. The 
Test-Dose Phase is designed to assess the safety, tolerability, and PK of USL261 in a 
monitored setting and provide the caregivers with training on the study procedures.

The Test-Dose Phase will be followed by the Comparative Phase, an outpatient, double-
blind, placebo-controlled, parallel-group phase. In the Comparative Phase, all subjects will 
be randomized 2:1 to receive 5.0 mg USL261 or placebo. During the Comparative Phase, 
the subject’s caregiver will administer the double-blind study drug when the subject 
experiences a seizure cluster that meets the study criteria, as described in the subject’s 
individualized Patient Management Plan (PMP). If the treated seizure cluster has not 
terminated within 10 minutes after the initial drug administration OR another seizure occurs 
between 10 minutes and 6 hours after administration of the study drug, AND the subject 
does not have < 8 breaths per minute, does not require emergency rescue treatment with 
assisted breathing or intubation and does not have excessive, uncharacteristic sedation (as 
defined by the investigator in the PMP), the double-blind dose of study medication may be 
followed by a single dose of 5.0 mg USL261. Any time between 24 to 120 hours after study 
drug administration, subjects and caregivers will return to the study center for a post-dose 
study visit (Visit 4). 
After Visit 3, the study coordinator or designee will call the caregiver or subject at least once 
each month until the subject has completed Visit 4 or has prematurely discontinued from the 
study.
After Visit 4, the subject will have completed the study and will be considered for 
enrollment in an open-label extension study, if one is offered at that time.
A maximum of approximately 350 subjects, aged 12 years or older, with a documented 
history of seizure clusters and on a stable AED regimen (no change in type[s] of drug) will 
be enrolled in the Test-Dose Phase. Before any subject continues to the Comparative Phase, 
safety data from at least 25 subjects in the Test-Dose Phase will be reviewed by an 
independent Data and Safety Monitoring Board (DSMB). Enrollment will temporarily halt 
once approximately 25 subjects complete the Test-Dose Phase, to allow the DSMB to 
review the safety data. If the safety data from this initial cohort supports continuation of the 
trial according to the DSMB, enrollment into the Test-Dose Phase will resume and the 
initial 25 subjects will proceed to the Comparative Phase. All subsequent subjects will 
progress directly from Test-Dose Phase to the Comparative Phase.

Screening
After subjects and caregivers have provided informed consent (and assent, where 
appropriate), subjects will undergo screening procedures at Visit 1 (see Table 1, Procedure 
Schedule). At Visit 1, training will be provided to the caregivers for self-study, which will 
be completed at or before Visit 2 (see Section 9.3.3). The screening period (time between 
Visit 1 and 2) will be a maximum of 28 days. The screening period may be extended in 
certain cases; however, the extension of the screening period must be approved by the 
Sponsor or CRO designee. If a screening period extension is granted for a given subject, that 
subject will have to undergo repeat screening laboratory and ECG assessments within 28 
days before Visit 2.
3.3
Test-Dose Phase
The Test-Dose Phase, which occurs at Visit 2, will take place at the study center under the 
supervision of the study investigator within 28 days of Visit 1. The investigator, or other 
qualified study personnel, will review, assess, and (if needed) re-instruct subjects and 
caregivers on the information provided in the self-study training (see Section 9.3.3). 
Caregivers must pass the CPR exam and demonstrate airway management techniques before 
subjects are given a test dose. 
Subjects who meet eligibility criteria at Visit 2 will receive a test dose of 5.0 mg USL261 
administered by a member of the study center personnel followed by a second dose of 5.0 
mg USL261 10 minutes later administered by the caregiver under the supervision of study 
center personnel. Caregivers and study center personnel will monitor the subject during the 
observation period for at least 4 hours after the test doses are administered and the

assessments outlined in Table 1 will be performed. After 132 subjects have completed the 
Comparative Phase, for all new test dosed subjects, caregivers and study center personnel 
will monitor the subject during the observation period for at least 1 hour after test dose 
administration. A subject who experiences signs or symptoms at Visit 2 that are concerning 
in the investigator’s judgment or are exclusionary per exclusion criterion #22 must be 
monitored until resolved or longer as deemed appropriate by the investigator.
At least one person who is trained and qualified to perform airway assessment and 
management, including endotracheal intubation (or local country/site equivalent) and 
Advanced Cardiac Life Support (ACLS) (or local country/site equivalent), will be available 
at the site for the entire observation period following the administration of the first test dose.
3.4
Comparative Phase
Subjects and caregivers will return to the study center for Visit 3 within 24 hours to 28 days 
of Visit 2 (unless DSMB review is not yet completed). The time between Visit 2 and Visit 3 
may be extended in certain cases; however, the extension must be approved by the Sponsor 
or CRO designee. At Visit 3, the investigator, or other qualified study personnel, will 
review, assess, and (if needed) re-instruct caregivers on the information provided in the self-
study training. Before subjects are randomized, caregivers must have demonstrated hands-
on competence in administering the study drug, performing timed respiration rate 
measurements and recording them in the practice Subject Worksheet, as well as demonstrate 
airway management techniques (see Section 9.3.3).
If the subject continues to meet eligibility criteria at Visit 3, he/she will be randomized to 
receive either USL261 5-mg or placebo. Caregivers will receive a study materials kit, 
which includes the Subject Workbook, the subject’s PMP, and the study drug kit. The PMP 
will specify the criteria for seizure cluster recognition, the procedure for contacting the 
central study nurse hotline after study drug administration, the requirements for 
administering a second dose of study drug (USL261), and a rescue protocol individualized 
for the subject.

During the Comparative Phase, caregivers will administer the double-blind study 
medication at the time of recognition of a seizure cluster that meets study criteria (according 
to the subject’s individualized PMP) and call the central study nurse hotline as soon as 
possible following study drug administration. If the treated seizure cluster has not 
terminated within 10 minutes after the initial drug administration OR another seizure occurs 
between10 minutes and 6 hours after administration of the study drug, AND the subject 
does not have < 8 breaths per minute, does not require emergency rescue treatment with 
assisted breathing or intubation and does not have excessive, uncharacteristic sedation (as 
defined by the investigator in the PMP), the second dose of study drug (i.e., 5.0 mg dose of 
USL261) may be administered. If the second dose of study drug (i.e., 5.0 mg dose of 
USL261) is administered, the caregiver will again call the central study nurse hotline as 
soon as possible after its administration. The caregiver will monitor the subject after study 
drug administration to record safety and efficacy measurements (see Section 6.1.4). 
If the subject encounters persistent seizure cluster activity or seizure recurrence (as defined 
in the subject’s PMP), has less than 8 breaths per minute, or is excessively and 
uncharacteristically sedated, caregivers will follow the rescue protocol in the subject’s PMP. 
The subject’s rescue protocol will outline rescue instructions individualized for the subject, 
including when and how to contact EMS (or local equivalent).
Subjects and caregivers will return to the study center 24 to 120 hours after study drug 
administration for Visit 4. Subjects who are prematurely discontinued from study 
participation or terminate their participation should return to the study center for Visit 4 
(Early Termination). The subject or caregiver will report to the investigator (or his/her 
designee) as soon as possible any significant medical event (including events that are life-
threatening or that result in death, hospitalization or prolonged hospitalization, persistent or 
significant disability, or incapacity of the subject) that occurs to the subject from the time 
written informed consent is obtained until completion of the final study visit (Visit 4 [Post-
Dose Assessment or ET]) or 7 days after last administration of study drug , whichever is 
later. The subject or caregiver may also call the central study nurse hotline at any time 
during the study for help or advice regarding study procedures.

(ICH) E6, Guidelines for Good Clinical Practice (GCP) and applicable regulatory

RATIONALE
4.1
Rationale for the Study
Although a substantial number of AEDs are currently marketed, a significant unmet need 
still exists in the treatment of epilepsy.  Current AED therapies do not adequately control 
seizures (ie, seizure-freedom) in as many as 30% of epilepsy patients.[37, 38] Breakthrough 
seizures can occur in subjects with previously controlled epilepsy and may result from 
problems with treatment compliance (e.g., forgetting to take medication) or waning efficacy 
of current regimen. This study seeks to evaluate the treatment success rate and safety of 
USL261 compared with IN placebo for the outpatient treatment of seizure clusters in 
subjects with partial or generalized epilepsy with a documented history of seizure clusters 
on a stable regimen of antiepilepsy treatment(s).
4.2
Rationale for the Study Design
The Test-Dose Phase was included to assess the safety, tolerability, and PK of USL261 in a 
monitored setting before subjects receive it as an outpatient during a seizure cluster. It will 
also allow study center personnel to effectively train the caregivers on study procedures, 
including study drug administration.  
The Comparative Phase, consisting of a double-blind dose followed by a second dose of 
study drug (i.e., 5.0 mg dose of USL261), which is administered only if the subject 
experiences treatment failure, was designed to study the efficacy of 5.0 mg USL261 versus 
placebo, while allowing for the possibility that some subjects may require a higher dose to 
terminate the seizure cluster. Since caregivers and subjects will be aware that the second 
dose is active, there may be a “progression bias” prompting some to declare treatment

failure and administer the second dose. To reduce this possibility, and to increase the safety 
exposure in this study, subjects will be randomized 2:1, USL261:placebo.
The duration of each subject’s participation will be determined by the frequency of observed 
seizure events. Assuming an average of 3 seizure clusters per year, approximately half of the 
study subjects will complete the study within ~4 months after randomization to treatment.
Subjects may remain in the Comparative Phase for up to 6 months. Any subject who has not 
treated a seizure cluster meeting the study criteria within 6 months of Visit 3 (Randomization) 
will be discontinued from the study.
4.3
Rationale for Dosing Regimen
The 5.0 mg dose of USL261 used for this phase III trial is based on safety data reported in 2 
ITI-sponsored clinical trials as well as the published literature. The ITI-sponsored clinical 
trials are described briefly below.

MZ0714: an open-label, 5-way crossover PK/PD safety trial in which 25 healthy adult
volunteers were randomly assigned to 1 of 5 treatment sequences. Subjects received
single treatments of USL261 at doses of 2.5 mg, 5.0 mg, and 7.5 mg; 2.5 mg midazolam
IV infusion over 15 min as sterile injection solution; and 5.0 mg midazolam sterile
injection solution administered intranasally.

MZ0815: an open-label, in-patient, PK/PD/safety study of ascending single dose and 2
doses of USL261 (2.5 mg, 5.0 mg, and 7.5 mg) given to 90 adult and adolescent
epilepsy patients on separate study visits separated by 3 or more days. At Visit 1
subjects received a single dose of USL261 (2.5 mg, 5.0 mg, or 7.5 mg). At Visit 2, the
subjects were provided a 2-dose regimen of USL261 with the total dosage ranging from
5.0 mg to 15.0 mg over a 15 minute period. The first dose of USL261 at Visit 2 was
identical to the dose strength of USL261 received at Visit 1. The second dose,
administered 15 minutes later, was either identical in strength to previous doses or lower
than the previously administered doses.

The PK parameters from the adult subjects in these 2 studies were generally similar, with 
the exception of AUC values, which were approximately 25 - 39% lower in MZ0815 
compared with those in MZ0714. This difference may be due to the different populations 
studied; healthy adults (MZ0714) versus patients diagnosed with epilepsy (MZ0815) who 
were taking concomitant medications, including AEDs known to induce CYP450 3A4. 
Data from MZ0815 showed increasing midazolam plasma concentrations with increasing 
doses. Midazolam Cmax was lower in adolescents as compared to adults.
The results from MZ0815 are similar to published PK data for midazolam in adults with 
epilepsy. In a study of 12 subjects with epilepsy, midazolam was administered IM in doses 
of 5.0 mg, 7.0 mg , and 10 mg. IM-administered midazolam resulted in a range of mean 
AUC values from 138 to 167 mg*hr/L and mean Cmax values from 22 to 78 ng/mL with no 
report of SAEs, such as respiratory depression.[12] Furthermore, data from the published 
literature demonstrate that 0.1 to 0.3 mg/kg of IV-approved midazolam administered 
intranasally (5 mg to > 20 mg fixed-dose per subject) effectively terminates seizure activity 
in most subjects.[21, 25, 39] These doses have seldom caused excessive sedation or 
respiratory depression.[40]
The 5.0 mg midazolam dose proposed for the Comparative Phase of this study is expected to 
be safe and efficacious. The 10 mg dose of midazolam provided by USL261 is well within 
the range of doses correlated with efficacy and has been found to be safe. [18, 31]
Based on the current literature, a single 5.0 mg dose of USL261 should provide the majority 
of subjects the appropriate balance of safety and efficacy. High inter-subject PK variability 
has been attributed to the cerebral GABA-A receptor binding characteristics of midazolam 
as well as the drug’s complex distribution and metabolism. Therefore, for subjects who do 
not respond by 10 minutes after administration of 5.0 mg USL261, a second 5.0 mg dose 
may be administered.

The primary reason for a subject’s premature discontinuation from the study should be 
selected from the following standard categories and documented in the source documents:

Adverse event: One or more clinical or laboratory events which, in the medical 
judgment of the investigator, are grounds for discontinuation even if the event does not 
appear to be related to study medication. The subject may withdraw because of an AE
even if the investigator does not feel that it is grounds for discontinuation. This category 
includes subject death.

Withdrawal of consent: Subject or Caregiver desires to withdraw from further 
participation in the study

Lost to follow-up: In the case of subjects who do not return for study visits and cannot 
be contacted, vigorous and repeated attempts (minimum of 3) by study center personnel 
to contact the subject should be made and recorded in the source data, e.g., telephone 
reports, letters, progress notes.  Attempts to contact the subject must include at least 1
certified mail receipt.  If all attempts to contact the subject have failed that subject is 
considered to be lost to follow-up and discontinued from the study.

Protocol violation: The subject findings or conduct failed to meet the protocol entry 
criteria or failed to adhere to the protocol requirements (e.g., change in AED drug during 
the study, subject’s caregiver withdraws from the study without a suitable replacement)

Subject has not experienced a seizure cluster meeting the study criteria within 6

eCRF, and the investigator should make every effort to perform all Visit 4 evaluations. In 
the event that a subject elects not to return to the study site for the ET Visit, the investigator 
must make every effort to contact the subject to review all AEs. If a subject discontinues 
prematurely due to an AE or SAE, the event will be followed until it resolves (returns to 
normal or baseline values) or stabilizes, or until it is judged by the investigator to be no 
longer clinically significant. In the case of subjects who do not return for study visits and 
cannot be contacted, vigorous and repeated attempts (minimum of 3) by the study center
personnel to contact the subject should be made and recorded in the source data, e.g.,
telephone reports, letters, progress notes.  Attempts to contact the subject must include at 
least 1 certified mail receipt. 
Replacement of Subjects:
Subjects who prematurely discontinue from the study after receiving double-blind study 
drug will not be replaced.
6.6
Treating Overdose
Refer to the Hospira Midazolam Injection, USP, Package Insert for full details on 
midazolam overdose (see Appendix 2).  In the case of suspected overdose, respiration, pulse 
rate, and BP should be monitored and general supportive measures should be employed. 
Attention should be given to the maintenance of a patent airway and support of ventilation, 
including administration of oxygen. An IV access should be obtained. Should hypotension 
develop, treatment may include intravenous fluid therapy, repositioning, judicious use of 
vasopressors appropriate to the clinical situation, if indicated, and other appropriate 
countermeasures. There is no information as to whether peritoneal dialysis, forced diuresis,
or hemodialysis is of any value in the treatment of midazolam overdose. Flumazenil, a 
specific benzodiazepine-receptor antagonist, is indicated for the complete or partial reversal 
of the sedative effects of benzodiazepines and may be used in situations when an overdose

with a benzodiazepine is known or suspected. However, the reversal of benzodiazepine 
effects may be associated with the onset of seizures in certain high-risk patients.  The 
prescriber should be aware of a risk of seizure in association with flumazenil treatment.
An overdose is not recorded as an AE unless signs or symptoms of the overdose occur, in 
which case the signs or symptoms are recorded as AE(s) and attributed to the overdose of 
study drug.
6.7
Pregnancy
If any female subject becomes pregnant while enrolled in the study, she must be 
discontinued from the study and undergo the ET visit (Visit 4) evaluations. The investigator 
must notify USL or its designee within 24 hours of learning about the pregnancy.  The 
investigator must complete the Pregnancy Notification Form provided by USL or its 
designee. The investigator must diligently follow the subject until delivery or termination of 
the pregnancy, providing necessary updated information to USL or its designee.
Information on the status of the mother and the child will be forwarded to USL or its 
designee. Generally, follow-up will occur within 6- to 8-weeks following the estimated 
delivery date.  Any premature termination of the pregnancy will also be reported.
Although pregnancy occurring in a clinical study is not considered to be an AE or SAE, any 
pregnancy complication or elective termination of a pregnancy for medical reasons will be 
recorded as an AE or SAE and will be followed as such. A spontaneous abortion is always 
considered to be a SAE.

ADVERSE EVENT MANAGEMENT
7.1
Definitions:  Adverse Events and Serious Adverse Events
An AE is any untoward medical occurrence in a clinical investigation subject administered a 
pharmaceutical product whether or not a causal relationship with this treatment exists.
REDACTED COP

lica
any extensions or variations thereof.

Upsher-Smith Laboratories, Inc.
An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding, for example), symptom, or disease temporally associated with the use of 
a medicinal product, whether or not considered related to the medicinal product.
Examples of AEs include, but are not limited to, the following:
Exacerbation of a pre-existing illness following the start of the study
Increase in frequency or intensity of a pre-existing episodic event or condition
Condition detected or diagnosed after the start of the study even though it may have been 
present prior to the start of the study
Condition that leads to a medical or surgical procedure (e.g., surgery, endoscopy, tooth 
extraction, transfusion) may be an AE, but the procedure itself is not an AE
An AE does not include:
Day to day fluctuations of pre-existing disease or conditions present or detected at the 
start of the study that do not represent a worsening of the disease or condition
Situations where an untoward medical occurrence has not occurred (e.g., hospitalizations 
for cosmetic elective surgery; medical or surgical procedures such as endoscopy, tooth 
extraction, or transfusion; social and/or convenience admissions)
The disease or disorder being studied or sign or symptom associated with the disease or 
disorder unless more severe or at an increased frequency than that expected for the 
subject’s condition. Accordingly, seizures in this subject population are anticipated, and 
therefore will not be considered AEs unless the investigator deems a particular seizure(s) 
to represent a worsening of the patient’s seizure disorder. Seizures that result in 
hospitalization or are considered to be medically significant will be considered to be 
SAEs and will be reported as stated in Section 7.2. 

Overdose of either study drug or concurrent medication without any signs or symptoms
The investigator will evaluate AEs using the following guidelines:

Description of Event (if the event consists of a cluster of signs and symptoms, a 
diagnosis should be recorded [e.g., flu syndrome] rather than each sign and symptom)
Onset Date 
Stop Date 
Intensity should be recorded as mild, moderate, or severe.  Intensity is defined as one of 
the following:
o
Mild:  awareness of sign or symptom, but easily tolerated
o
Moderate:  discomfort sufficient to cause interference with normal activities
o
Severe:  incapacitating, with inability to perform normal activities
It is important to distinguish between SAEs and severe AEs.  Severity is a measure of 
intensity whereas seriousness is defined by the criteria provided below.  An AE of severe 
intensity need not necessarily be considered serious.  For example, a migraine headache that 
incapacitates a subject for many hours may be considered a severe AE but not a serious AE 
(SAE).
Seriousness: As provided in FDA Title 21 CFR Part 312 and the guidelines of ICH GCP 
(CPMP/ICH/135/95), an SAE is any untoward medical occurrence that at any dose:
o
Results in death
o
Is life-threatening: 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 which hypothetically might have become life-threatening or 
caused death if it were more severe.
o
Requires inpatient hospitalization or prolongation of existing hospitalization: 
Complications that occur during hospitalization are AEs.  If a complication prolongs 
hospitalization or fulfills any other serious criteria, the event is serious.  
Hospitalization for elective treatment of a pre-existing condition that did not worsen 
from baseline is not considered to be an AE. Hospitalization requires an admission to 
the hospital.
o
A persistent or significant incapacity or substantial disruption of the ability to 
conduct normal life functions.

Pregnancy).
o
Important medical events that may not be immediately life-threatening or result 
in death or hospitalization but may jeopardize the subject or may require 
medical or surgical intervention to prevent one of the outcomes listed in the 
definition above should also be considered serious. Examples of such events are 
intensive treatment in an ER or at home for allergic bronchospasm, or blood 
dyscrasias that do not result in hospitalization; or development of drug dependency or 
drug abuse.  
For this study, the diagnosis of status epilepticus (as determined by the investigator)
will ALWAYS be considered serious and follow the procedure for reporting SAEs.
The investigator must record whether or not the AE meets the definition of serious.  If the 
event is serious, the investigator must complete an SAE Report Form.
Relationship to Study Drug
The investigator must make a causality assessment (relationship to study drug) based on the 
following four causality terms:
o
Related:  Study drug and AE occurrence definitely related in time and AE more 
clearly or more likely explained by study drug exposure than by other mechanism.
o
Possibly Related: Study drug administration and AE occurrence reasonably related 
in time and the AE explained equally well by causes other than study drug.
o
Unlikely Related: Study drug administration and AE occurrence is not reasonably 
correlated with study drug administration or the AE is possibly explained by another 
cause.
o
Not Related:  The time or occurrence of the AE is not correlated with study drug 
administration or the AE is clearly explained by another cause.

Frequency:  The investigator must record whether the AE is a single event or an 
intermittent event (an AE that occurs more than once and each event is considered to be 
of the same intensity/not worsening).  
Outcome: Outcome of AEs should be recorded as resolved, resolved with sequelae, not 
resolved, improved, or fatal.  If an AE is not resolved at the time of discontinuation, the 
AE should be followed until it is resolved (returns to normal or baseline) or the subject’s 
condition has stabilized, or until it is judged by the investigator to be no longer clinically 
significant or, when applicable, the subject is receiving appropriate medical care.
Action Taken: All applicable action(s) taken with regard to study drug should be 
recorded as either no change, permanent discontinuation or temporarily stopped.
7.2
Reporting of Adverse Events and Serious Adverse Events
The Investigator is responsible for the detection and documentation of events meeting the 
criteria and definition of an AE or SAE, as provided in Section 7.1.  All AEs and SAEs that 
are observed, queried, or spontaneously volunteered by the subjects occurring from the time 
written informed consent is obtained until completion of the final study visit (Visit 4 [Post-
Dose Assessment or ET]) or7 days after last administration of study drug, whichever is later,
will be recorded in the source documents and will be entered on the appropriate eCRF even 
if the AE or SAE is assessed by the Investigator as not related to study drug.  Information to 
be collected includes the nature, date of onset, stop date, intensity, duration, treatment, 
causality, and outcome of the event.  SAEs that occur after completion of the final study 
visit (Visit 4 [Post-Dose Assessment or ET]) or 7 days following the last administration of 
study drug, whichever is later, will be collected only if they are considered by the 
investigator to be related to study drug.
All SAEs, regardless of expectedness or causality, must be reported on the SAE Report 
Form by email or fax to inVentiv Health Clinical immediately, but no later than 1 business 
day of the Investigator’s or any other study center personnel’s knowledge of the event as 
described below.  In the event of any fatal or life-threatening SAE, the Investigator must 
also inform a Medical Monitor at inVentiv Health Clinical by telephone or email 
immediately.  In addition, any AE resulting in permanent study discontinuation for a subject
must be reported within 2 business days to the Medical Monitor.

Clinical Laboratory Abnormalities and Other Abnormal 
Assessments
Abnormal laboratory findings should not be listed on the AE eCRF page unless signs or 
symptoms are present or the laboratory finding is deemed clinically significant by the 
Investigator (confirmed by repeat laboratory testing).  If a laboratory value or assessment is 
related to a medically defined new or worsening of a preexisting diagnosis or syndrome, the 
diagnosis or syndrome will be recorded on the AE eCRF page, not the individual laboratory 
values.  If a medically defined diagnosis or syndrome cannot be made and the subject is 
asymptomatic, a clinically significant laboratory value will be recorded as an AE.
All clinically significant abnormal laboratory results or assessments will be followed until 
they resolve (return to normal or baseline values) or stabilize, or until they are judged by the 
Investigator to be no longer clinically significant.

RANDOMIZATION AND BLINDING METHODS
8.1
Randomization
At Visit 1, the investigator, or designee, will contact the Interactive Response Technology 
System (IRT) to register the subject. At Visit 2, the investigator, or designee, will contact 
IRT to confirm the administration of the test dose. At Visit 3, subjects meeting the 
eligibility criteria will be randomized (2:1) to receive USL261 or matching placebo using
the IRT; the Investigator, or designee, will obtain a drug kit number via IRT at Visit 3. 
Instruction on access and use of the IRT service will be detailed in the IRT manual provided 
by the IRT vendor.
The randomization code will be generated by an unblinded statistician at the CRO [inVentiv 
Health Clinical] who is not otherwise involved in study activities. The randomization will

be generated using fixed blocks and will be stratified by age (< 18 vs. ≥18). USL will not 
have access to the randomization code.
8.2
Blinding 
USL261 will not be blinded for the Test-Dose Phase or for the second dose provided to 
some subjects during the Comparative Phase; however, blinding is considered important for 
safety and efficacy assessments for the first dose of the Comparative Phase. Therefore, drug 
supplies for the first dose in the Comparative Phase will be labeled in double-blind fashion 
with information including the protocol number, kit identification number, and instructions 
for use. The drug name will not appear on the label, and neither the investigator/study 
center staff nor the subject/caregiver will know the identity of the randomized medication.
The interim analyses will be conducted by an unblinded statistician and reviewed by an 
unblinded interim monitoring committee, both independent of the sponsor. The sponsor, 
USL, will remain blinded throughout the trial until database lock has occurred. Once 
database lock has occurred, the final statistical analysis of this trial will be performed by a 
CRO under the direction of USL.
If it is medically imperative to know what study treatment the subject is receiving, the
investigator or designee will contact the IRT and select the option for exposing the blinded
information. The individual who breaks the blind must record the date and rationale in the
subject’s medical records and on the eCRF. In such cases, the investigator or designee 
should contact the Medical Monitor before the blind is broken (if possible). Every effort 
should be made to collect complete efficacy and safety data on these subjects. Furthermore, 
inVentiv Health Clinical will also have the capability to unblind individual subject data for 
the purposes of fulfilling regulatory reporting requirements for unexpected AEs, which is in 
compliance with ICH guidelines.

MATERIALS AND SUPPLIES
9.1
Study Drug
USL261 contains midazolam, EP/USP, as the active ingredient, and the inactive ingredients 
USP. A 5.0 mg dose of USL261 (0.1 mL dose of a filtered midazolam 50 mg/mL solution) 
is delivered with a single actuation of the unit dose pump.  The dosage unit contains 
sufficient solution to provide a single 5.0 mg dose of USL261 and overfill for the pump to 
work correctly.
Midazolam, the active ingredient in USL261, is designated as a Schedule IV controlled 
substance with abuse potential by the US Controlled Substances Act (21 CFR §1308).
The placebo nasal spray will consist of the same inactive ingredients as found in the 
USL261:
 
 Each actuation of the unit dose pump will deliver 0.1 mL of this 
solution.
9.1.1
Controlled Substance Documentation 
Midazolam is a controlled substance (Schedule IV) under the US Controlled Substances Act 
(21 CFR §1308). Prior to shipment of study drug, the investigator must provide USL or 
designee with a copy of a controlled substance license (or local country equivalent) that 
clearly identifies the registrant, and address of the registrant.  Study drug supplies will be 
shipped to the registrant and address noted on the certificate.
9.2
Study Drug Labeling
USL261 and placebo nasal spray containers will be provided as ready-to-use assemblies 
packaged to prevent accidental actuation. Both active and placebo drug utilize a Unit Dose 
Nasal Spray System consisting of a stoppered glass vial containing study drug which is 
inserted into a vial holder, which is in turn held in a white plastic nasal spray actuator. The

vial holder is pushed into the nasal actuator, which sprays the dose out of the nasal spray 
actuator tip.
Study drug (active and placebo) will be shipped to an authorized and licensed drug 
distribution company or companies for labeling and packaging. Since the active drug 
product is classified as a Schedule IV Controlled Substance (21 CFR §1308), all clinical 
supplies will be stored, distributed, and destroyed in compliance with US Drug Enforcement 
Administration (DEA) regulations.
The study drug supplies will be labeled appropriate to their use. USL261 5.0 mg containers 
for the Test Dose Phase and the second dose of the Comparative Phase will be identified as 
open-label treatments. The label for the double-blind, first dose of the Comparative Phase 
will contain at a minimum the following information for the US (additional items will be 
added as required for other study countries):

Protocol number

Kit identification number from the randomization scheme

Instructions for use
“Caution: New Drug – Limited by Federal law to investigational use” will also appear on 
the immediate package of each nasal spray product used during the study as required by 
21 CFR §312.6.

Patient Management Plan
An individualized PMP will be prepared by the investigator or designee for each subject
based on information provided by the subject (when able) and caregiver(s). 
The individualized PMP will describe, at a minimum, the type of seizure cluster eligible for 
treatment with study drug, the criteria for seizure cluster recognition, when to administer the 
study drug, when to call the central study nurse hotline, requirements for when to give the 
second dose of study drug (ie, 5.0 mg dose of USL261), and a rescue protocol for persistent

or recurrent seizure activity or other safety concern. Contact information for study center 
personnel, the central study nurse hotline and emergency medical service(s) will also be 
listed in the PMP.
The following steps will be followed for PMP preparation:
1. At Visit 1, the subject and caregiver each provide the investigator (or designee) a 
description of both the seizure clusters and the typical, non-clustering seizures (if 
any) in their own words.
2. The investigator (or designee) will add his/her notes to the subject and caregiver 
descriptions, specifying what type of seizures each description refers to and any 
other relevant information.
3. The PMP is drafted by the investigator and qualified study center personnel
using the template provided by the Sponsor or CRO.
4. The PMP, including the seizure cluster descriptions from the subject, caregiver, 
and investigator, are then provided to an expert Central Reviewer for a final 
determination of whether or not the subject qualifies for study inclusion and 
input on whether further information is needed.
5. The PMP is finalized by the investigator and qualified study center personnel
before the subject receives the first test dose at Visit 2. The PMP will be 
discussed and agreed upon by the subject, caregiver, and investigator.
6. Subjects and caregivers will receive a copy of the PMP at Visit 3.  A summary of 
the PMP (i.e., laminated card for convenient reference) will also be provided.
If the Central Reviewer does not approve the subject for study participation, the subject will 
be screen failed.

outpatient information during the Comparative Phase of this study. The Subject Workbook
will be used to record:

Seizure activity (Seizure activity will be documented by legibly recording the date 
and time of onset of each seizure, the date and time of seizure termination, the type 
of seizure experienced, and any treatment intervention [medication, call for EMS] 
for each seizure or seizure cluster. Unwitnessed seizures should also be recorded, 
with the information [e.g., date, seizure start, and stop time] estimated to the best of 
the subject’s or caregiver’s ability. The caregiver will document in the Subject 
Workbook all seizure activity that occurs from the time the subject and caregiver 
receive the study materials kit at Visit 3 until Visit 4 or ET).

The date and time of study drug administration 

The subject’s respiration rate at specified time points after study drug administration

The date and time of return to baseline function after the treated seizure cluster (as 
assessed by the caregiver)

Medications that the subject received and device use by the subject within 24 hours 
after study drug administration

All other safety observations 
The Subject Workbook will also contain information and instructions for administering 
study drug, assessing respiration rate, and completing the Subject Workbook. The caregiver 
will be instructed by the study center personnel as to how to complete the Subject 
Workbook. The subject or caregiver is required to return the completed Subject Workbook 
to qualified research staff at Visit 4 or ET.
At Visit 2, the caregiver will enter timed respiration rate measurements into a practice 
Subject Worksheet for training purposes (see Section 9.3.3).

Caregiver Training Materials
Caregivers will be trained in study procedures by qualified study personnel beginning as 
early as Visit 1 and retrained, if necessary, at Visits 2 and 3. Training will be provided to 
the caregiver(s) at Visit 1 for self-study on the following topics:

Overview of the study

Understanding the subject’s individualized PMP

Recognizing a cluster seizure episode

Procedures for study drug administration

Mandatory requirement for contacting the central study nurse after subject is treated
with double-blind study drug and the second dose of study drug (i.e., 5.0 mg dose of
USL261), if needed

Performing study-related measurements (e.g., measuring respiration rate, completing
the Subject Workbook)

Procedures for safety monitoring

Cardiopulmonary resuscitation (CPR) including airway management

Contact information for help and advice from study center personnel and a toll-free
telephone hotline to a central study nurse (available 24 hours a day, 7 days a week)
The training provided at Visit 1 for self-study will be completed at or before Visit 2. 
Completion of the self-study training will be certified by qualified study staff and/or by 
web-based or paper-based questionnaire. The investigator, or other qualified study 
personnel, will review, assess, and (if needed) re-instruct subjects and caregivers on the 
information provided in the self-study training at Visits 2 and 3. Before subjects are given 
the test dose at Visit 2, caregivers must pass the CPR exam, which addresses airway 
management, breathing, and circulation and must demonstrate airway management 
techniques including neck extension, chin lift, and jaw thrust maneuvers. During Visit 2, 
the primary caregiver will administer the second test dose and monitor the subject by 
performing timed respiration rate measurements. Respiration rate assessed by the caregiver
will be recorded in a practice Subject Worksheet at Visit 2.

Before the subject is randomized, caregivers must have demonstrated hands-on competence 
in administering the study drug, performing the timed respiration rate measurements, 
recording information in the practice Subject Worksheet, and performing the correct 
technique for airway management. The investigator or his/her designee will confirm that the 
subject and caregiver clearly understand the study procedures (e.g., requirements for 
documenting seizure activity, timing for respiration rate monitoring, etc.) before leaving the 
study center at Visit 3.
Caregivers that are added during the study will have to complete similar training 
requirements as those noted above.
9.4
Study Drug Inventory and Storage
USL requires sponsored investigators to maintain adequate drug inventory and security at all 
times. Upon receipt of the study drug, the investigator or designee will perform an 
inventory of the shipment, comparing the shipment inventory to actual study drug received, 
and complete and sign an inventory log. The investigator or designee must count and verify 
that the shipment contains all the items appearing on the shipment inventory. The 
investigator must immediately notify USL (or designee) or the drug distribution contractor 
of any damaged or unusable study drug that the site receives, and document any damaged or 
unusable study drug in the inventory log.
Only after receipt of all required documentation from a clinical site will USL or its designee 
notify the drug distribution contractor to distribute the initial study drug to that center. 
Additional study drug will be shipped as needed. The investigator or designee will retain a 
copy of the shipment inventory received with the drug supply in the study file and forward 
the original to the drug distribution center. Each time study drug is dispensed to a 
subject/caregiver, the investigator or designee will record the quantity and a description 
(e.g., kit identification code, subject code) on the drug accountability log. The 
investigator/designee will also document any subsequent returns or losses of study drug on 
the drug accountability log.

Drug accountability records will be available to the study monitor for review at each site 
visit. The study monitor will inspect drug supplies and accountability records throughout 
the study conduct at the study center to confirm inventory control and proper study drug 
storage. The study monitor will record any discrepancies and/or deficiencies and report 
them to the investigator and to USL or designee and will document the investigator’s plan 
for resolution of any drug inventory or storage issues.
9.4.1
Drug Storage at Research Centers
Since midazolam is a controlled substance (Schedule IV), drug supplies must be kept in a
securely locked, substantially constructed enclosure with limited access (e.g., locked
cabinet). The investigator will take adequate precautions to prevent theft or diversion of the 
study medication, consistent with 21 CFR § 312.69. Within the locked storage area, study 
drug will be stored at a controlled room temperature (with excursions between 15° and 30°C
[59° and 86°F]) until used. 
Before an investigator is allowed to participate in this study, the drug storage area at his/her 
site must be inspected by USL or designee. The study monitor (or designee) will also 
discuss drug storage responsibilities with the investigator.
9.4.2
Dispensing of Study Drug
All study medication will be dispensed by the study center pharmacist or other qualified 
individual, and each test dose or study drug kit dispensed will be documented in the drug 
accountability log.
The USL261 test doses (2 USL261 5.0 mg containers) will be dispensed to study personnel 
at Visit 2.
If the subject continues to meet all eligibility criteria at Visit 3, the pharmacist or other 
qualified individual at the study center will call the IRT to obtain the kit identification 
number. The appropriate study drug kit, which contains blinded study drug and the second 
dose of study drug (i.e., 5.0 mg dose of USL261), will then be documented and dispensed to

personnel will also tell or remind subjects/caregivers to:

Store study drug at controlled room temperature (see Section 9.4.1), and

Return study drug containers, both used and unused, to clinic staff at the next visit
9.4.3
Return or Destruction of Study Drug
At Visit 4 or ET, the subject/caregiver must return all used and unused study drug containers
to the study center, which the staff will collect for reconciliation. 
At the conclusion of the study, a final inventory of study drug shipped to the site, dispensed, 
and remaining at the site will be performed by the Study Monitor (or designee) and the 
investigator (or designee). This reconciliation will be logged on the drug accountability 
form, signed, and dated. If any supplies are missing, this must be indicated on the drug 
accountability/return forms along with an explanation of the discrepancy. Any 
discrepancies noted will be investigated, resolved, and documented before return or 
destruction of unused study drug. The investigator or designee must return all used and 
unused medication to USL or designee unless alternative arrangements for drug disposal are 
authorized by USL. Drug accountability records should be returned to USL or designee, 
and the investigator or designee must retain copies of these drug accountability records for 
his/her files in accordance with 21 CFR § 312.59.
No study drug will be retained at any clinical site when the study is completed; all study 
drugs will be returned to USL or designee for destruction.

10.5.1
Primary Efficacy Endpoint and Analysis
The primary efficacy endpoint is the proportion of subjects who meet the criteria for
Treatment Success. Treatment Success is a composite measure of efficacy that will be 
assessed based upon the first seizure cluster treated with study drug during the Comparative 
Phase.  Treatment Success is defined as achieving the following:

Termination of seizure(s) within 10 minutes after study drug administration, and

No recurrence of seizure(s) beginning 10 minutes after study drug administration to 6
hours after study drug administration
Subjects who receive the second dose of study drug within 6 hours of the first dose during 
the Comparative Phase (i.e., USL261 5.0 mg) will not meet the definition of Treatment 
Success.
The null hypothesis is that there is no difference in the proportion of subjects with 
Treatment Success in the USL261 and placebo groups. The alternative hypothesis is that 
the Treatment Success rate will be different between the USL261 and placebo groups.
The primary efficacy endpoint will be analyzed by Fisher’s Exact Test using the mITT 
Population.  The 95% confidence intervals (CIs) around the proportions will be reported. 
Chi-squared test will be performed as a sensitivity analysis.
The components of the primary endpoint (seizure termination and recurrence) will also be 
analyzed separately using Fisher’s Exact Test.
Additional exploratory analyses may be conducted; details will be provided in the SAP.
10.5.1.1
Missing Data and Sensitivity analysis for Primary Outcome
Subjects who do not have sufficient available data to confirm whether they can be classified 
either as “Treatment Success” or as “Not a Treatment Success” are considered to have missing 
data. Subjects with missing data impacting determination of Treatment Success will be 
assumed to have had an unfavorable outcome and will be treated as not a Treatment Success.

Secondary Efficacy Endpoints and Analyses
The secondary efficacy analyses will be performed on the mITT population. The secondary 
efficacy endpoints include the following:

Proportion of subjects with recurrence of seizure(s) beginning 10 minutes after
administration of double-blind study drug to 4 hours after administration of double-blind
study drug
o
Subjects who have been administered the second dose of study drug (i.e., 5.0 mg
dose of USL261) within 4 hours of double-blind study drug administration will
be assumed to have had a seizure.
o
The proportion of subjects with occurrence of seizure(s) within 4 hours after
administration of study drug will be analyzed using Fisher’s Exact Test. The
95% CIs will be presented for the proportion. In addition, Chi-squared test will
be performed as a sensitivity analysis.

Time to next seizure with a start time > 10 minutes after study drug administration
o
Subjects who do not have another seizure before the end of the 24-hour
observation period, and have not been administered the second dose of study
drug (i.e., 5.0 mg dose of USL261) will be censored at the end of the observation
period.
o
Subjects administered the second dose of study drug (i.e., 5.0 mg dose of
USL261) that did not have a seizure before the administration of second dose of
study drug (i.e., 5.0 mg dose of USL261) will be censored at the time of the
second dose (USL261) administration.

Analyses for Subjects Receiving 2 Doses of Study Drug
It is important to assess the subject’s response to the second dose of study drug (i.e., 5.0 mg 
dose of USL261) in order to evaluate the usefulness of the split-dose strategy. Data from 
subjects randomized to receive double-blind USL261 and who subsequently received the 
second dose of study drug (i.e., 5.0 mg dose of USL261) will be analyzed to determine:

The proportion of subjects who satisfy the Treatment Success criteria relative to the
timing of the second dose of study drug (i.e., 5.0 mg dose of USL261); the analysis and
definition of Treatment Success will be similar to the primary efficacy variable
described in Section 10.5.1.
10.5.4
Safety Analyses
Safety will be assessed through the collection of AE reports, OAA/S (Sum and Composite 
scores), requirements for unscheduled ER or EMS visit(s), vital signs, caregiver-recorded 
respiration rates, laboratory evaluations, ECGs, physical, nasal and neurological 
examinations, and C-SSRS scores. All safety analyses will be presented by phase of the 
study based on the Safety Population and Randomized Safety Population, unless otherwise 
specified.
Safety data from both the Test-Dose Phase and the Comparative Phase will be summarized.

discontinuation will be summarized. In addition, listings of all TEAEs, SAEs, and AEs 
leading to discontinuation will be presented.
Clinical Laboratory Data: Clinical laboratory results for serum chemistry, hematology, 
and urinalysis will be presented by treatment received and visit using summary statistics.  
Changes from baseline will also be displayed. Normal range shift tables will be generated 
for each parameter.  In addition, clinically significant abnormalities, as predefined in the 
SAP, will be tabulated.
Vital Signs Measurements: Vital signs measurements performed by study site staff will be 
presented using descriptive statistics. Systolic and diastolic BP (mmHg), HR (bpm), RR
(breaths per minute), and temperature (degrees Celsius) will be summarized at each visit and 
time point.  Changes from baseline will also be displayed. 
Caregiver-recorded respiration rate: Caregiver-recorded respiration rates will be

(WinNonlin Enterprise version 5.2 or higher).The following PK parameters of midazolam 
and 1-hydroxymidazolam will be calculated from data obtained for the PK Population:
•
AUC0-t – the area under the plasma concentration-time curve (AUC) from time 0 to time
t, where t is the last measurable concentration, estimated using the linear trapezoidal rule
•
AUC0-inf – the AUC from time 0 extrapolated to infinity, calculated by adding Ct/λz to
AUC0-t, where Ct  is the last quantifiable concentration and λz is the elimination rate
constant

(“0”). Actual sampling times will be used in the calculations of pharmacokinetic parameters.
Descriptive statistics will include the number of observations, mean, geometric mean, 
standard deviation (SD), and coefficient of variation, as well as median, minimum, and 
maximum for the PK variables. Additional descriptive statistics will be provided by sub-
group such age group, gender, race, etc. Exploratory analysis assessing the relationship 
between PK parameters and selected baseline characteristics may be conducted if 
applicable.  
10.6.2
Pharmacokinetic/Pharmacodynamic Variables and Analyses
The PK/PD analysis of data from the test dose will consist of correlating the plasma 
midazolam plus 1-hydroxymidazolam concentrations to respiratory rate, BP, HR, O2
saturation, and sedation based on OAA/S scores. Regression analysis will describe the 
PK/PD relationship, if one exists. If appropriate, for those PD measurements found to 
correlate to plasma concentrations, the influence of covariates such as gender, AED inducer 
status, weight, BMI, race, and age group will be explored.

a)
In this study sequential doses were administered at the onset of seizure, 4 hours (children and adults) and 12 hours (adults only) 
post first dose. Therefore, only the data out to 4 hours post first dose was used.
b)
Response rates were extracted from Kaplan-Meier curves.
In this meta-analysis the outcomes from the three different studies are relatively consistent
with an estimated pooled common Odds Ratio of 2.90, which is significantly lower than 3.5 
assumed Odds Ratio in the original protocol.  With the originally planned sample size of 
132 subjects who have completed the Comparative Phase the power is estimated to be 75%, 
much lower than the targeted 90% power.  Therefore, a classic group sequential design, with 
3 interim analyses and a maximum sample size of 240 subjects who have completed the 
Comparative Phase is proposed in order to reach sufficient overall power (approximately 
90%) for this study with possible study stopping at interims for efficacy or futility.
In this group sequential design, interim analyses will occur after 132, 165, and 204 subjects 
have completed the Comparative Phase.  At any interim analysis the trial may stop early for 
either efficacy or futility.  Assuming a 0.40 placebo rate with the updated odds ratio of 2.9, 
the overall power of this design is approximately 90%, while maintaining 2.5% type I error.  
All interim analyses will be performed using the mITT population and a one-sided test 
comparing two proportions.  Interim analyses will be conducted by an unblinded statistician 
and reviewed by an unblinded Interim Analysis Monitoring Committee (IAMC), both 
independent of the sponsor.  IAMC membership, responsibilities, timelines, and 
communication channels will be clearly specified in a charter.  In particular, the IAMC

communication channels with the sponsor will be limited to maintain the blind of the 
sponsor study team in order to minimize the chance of operational bias.   To this end, the 
IAMC will inform senior management first of the decision to continue the trial or stop 
according to the statistical analysis plan.  Senior management will in turn inform the team to 
continue or not to continue the study only with no further information on the interim 
analysis.
In order to achieve the maximum sample size of 240 subjects who have completed the 
Comparative Phase, 350 subjects will be enrolled in the Test-Dose Phase to account for the 
approximate 32% of subjects test dosed that do not complete the requirements for efficacy 
evaluation (receive at least 1 dose of study drug during the Comparative Phase and who 
complete Visit 4).
10.8
Interim Analyses for Success
At the sample sizes of N=132, 165, 204, and 240 subjects completing the Comparative 
Phase, a one-sided test of two proportions is performed to determine the test value to 
compare to the critical value obtained from a Lan-DeMets alpha spending function 
approximating a Pocock boundary.  Complete details for the critical values at each interim 
analysis and simulation results are provided in the SAP.
10.9
Interim Analyses for Futility
At each of the prespecified interim analyses (N=132, 165, 204, futility is not applicable at 
the N=240 final analysis) the predictive probability of success at the maximum sample size 
is computed.  This calculation begins by assuming uniform prior distributions Beta (1,1) on 
probability of treatment success in the control arm (pC) and the probability of treatment 
success in the treatment arm (pT) and computing the posterior distribution with the currently 
available data. The predictive distribution of the final data assuming the maximal sample 
size of N=240 is then computed.  The number of future treatment successes for each arm has 
a Beta-Binomial distribution which is then added the fixed number of current treatment 
successes in each arm.  We may then compute the predictive probability that a trial success 
is reached at N=240 subjects completing the Comparative Phase.  If this predictive 
probability is less than 10%, the trial will be stopped for futility.  Note that the success

and/or caregivers that are still active in the study will be re-consented using the new form(s).
11.3
Study Personnel
The investigator should maintain a list of appropriately qualified persons who are delegated 
to perform significant study-related duties.  In addition, the investigator should maintain a 
signature sheet to document signatures, initials, and study responsibilities of all persons 
authorized to make entries and/or corrections to the eCRF.
11.4
Ongoing Information for Independent Ethics Committee
Unless otherwise instructed by the IRB/IEC, the investigator or designee must submit to the 
IRB/IEC at a minimum:
Information on SAEs from the investigator’s site, as soon as possible
Expedited safety reports from the sponsor or its representatives, as soon as possible
Periodic or annual reports on the progress of the study
11.5
Completion of Electronic Case Report Forms
The investigator is responsible for the quality of the data recorded for this study.  These
recorded data should be a complete and accurate account of each subject’s record collected 
during the study.  Subject data that are collected may be substantiated by 2 types of source 
documents at the study center, paper and electronic (electronic source data is defined as 
electronic information not directly entered into the EDC system). Source data collected 
electronically or via paper will be entered onto the eCRFs in the EDC system. The Subject 
Workbook completed by the caregiver is considered a source document. The eCRFs will be 
completed according to guidelines provided by USL or its designee.
Access to the EDC system will be granted to trained and authorized study personnel only, 
and user IDs and passwords must not be shared with other individuals.  Only staff

notebook will be eligible to enter or make edits to the data. Qualified research personnel 
will accurately enter data from both clinic- and subject/caregiver-generated source 
documents into the eCRFs provided for this study. Data will be entered into the eCRF
shortly after each subject’s visit. Study center personnel will exercise due diligence to 
ensure that study data are entered accurately and in their entirety from the study center’s 
source documents into the appropriate data fields. 
The investigator must review all data entries on a regular basis for completeness and 
accuracy.  When changes or corrections are made to existing entries in the EDC system, the 
reason for the change must be clearly delineated. The investigator agrees to transfer study 
data into the EDC system in a timely fashion and to make the records available to the study 
monitor for full inspection.  In addition, data queries should be answered promptly.
Although the study eCRF is the primary database for the study, all data entered into the 
eCRF must be recorded in the source documents, and any missing data must be explained. 
Source data will be retained by the study center as described in Section 11.12, Records of 
Study.
At the end of the study, by electronically signing the eCRFs the investigator is attesting to 
his/her responsibility for the quality of all data recorded, as well as attesting that the data 
represents a complete and accurate record of each subject’s participation in the study.
11.6
Study Monitoring
USL, as sponsor of this study, is responsible to regulatory authorities for ensuring the proper 
conduct of the study as regards to protocol adherence and validity of the data recorded on 
the eCRFs presented to the regulatory authorities.  USL (or designated CRO) has therefore 
assigned study monitors and medical monitors to this study.  Their duties are to aid the 
investigator and at the same time, USL, in the maintenance of complete, legible, 
well-organized, and easily retrievable data.  In addition, a monitor will explain and ensure 
the investigator’s understanding of all applicable regulations concerning the clinical 
evaluation of a pharmaceutical product (whether licensed or unlicensed) and ensure an 
understanding of the protocol, reporting responsibilities, and the validity of the data.

In order to perform their role well, the monitors must be given direct access to primary 
subject data that support data on the eCRFs for the study (e.g., hospital and general practice 
charts, appointment books, original laboratory records).  The investigator must exercise 
judgment regarding information in a subject’s chart that is not relevant to the performance, 
observations, or conduct of this study.  The investigator must make available such records to 
USL, designated CRO, quality assurance, IRB, and regulatory personnel for inspection and 
copying.  Because this enters into the realm of subject confidentiality, this fact must be 
included in the information signed by the subject.
The investigator should agree, as a minimum requirement, to record the following 
information in the subject notes:
Protocol identification number
Date that the subject gave written informed consent
All visit dates
All AEs
All concomitant medications
Entries in the subject notes must contain the signature or initials of the person making the
entries.
The study monitor will perform source data verification at each monitoring visit.
11.6.1
Data and Safety Monitoring Board
The study will be conducted under the supervision of an independent DSMB (see Section 
10.5.5, Data and Safety Monitoring Board). All DSMB members have extensive experience 
in either clinical trials and/or management of seizures. The DSMB is responsible for the 
ongoing review of a clinical trial and for making recommendations concerning the 
continuation, modification, and termination of the trial.

Prohibited Concomitant Substances
The medications listed below are prohibited from Visit 1 through Visit 4 / ET. If the subject 
was taking any of these medications at or before Visit 1, the time between the last dose of that 
substance and Visit 2 must be equal to or greater than the minimum washout time shown 
below. 
The first listing of substances represents inhibitors or inducers of the cytochrome P450 3A
family of enzymes, and may alter the PK of midazolam. Food or beverage substances are 
shown in italic font; drugs, herbals, or nutritional supplements are shown in regular font.
The second listing of substances represents opioids, or other respiratory depressants or other 
sedating medications.
The following substances are prohibited when administered orally, by injection, or any other 
method intended for systemic delivery. Usage of topical, intravaginal, or ophthalmic 
formulations containing prohibited substances is allowable provided that the usage is unlikely 
to achieve meaningful systemic levels. These lists may not be all-inclusive; direct any

Protocol Number: P261-401
Protocol Title: 
A Randomized, Double-Blind, Placebo-Controlled Study of the Safety and Efficacy of 
Intranasal Midazolam (USL261) in the Outpatient Treatment of Subjects with Seizure 
Clusters
ARTEMIS-1: Acute Rescue Therapy in Epilepsy with Midazolam Intranasal Spray-1
REASON FOR CHANGE TO PROTOCOL
Change 1
While the most common peripheral cause of dysosmia is olfactory neuron loss due to upper 
respiratory tract infection (URTI), nasal products have also been associated with smell 
disturbances. For example, Zicam Cold Remedy Nasal Gel and Swabs, was withdrawn from 
the U.S. market in 2009 due to long lasting or permanent loss of smell. The Brief Smell 
Identification Test (B-SIT) was added to assess the effects of USL261 on olfaction.
Change 2
The procedures to be completed at Visits 1, 4, and on the monthly telephone follow-up calls
between Visit 3 and Visit 4 have been updated to add collection of the number of calls to 
EMS and ER visits for a seizure cluster or other seizure emergency prior to Visit 1 and 
during the study. This change has been made to allow for collection of number of calls to 
EMS and ER visits due to seizure emergencies prior to and during the study beyond use of 
EMS, ER, or the Rescue Protocol in the 24 hours after study drug administration. This will 
allow for assessment of healthcare utilization while USL261 is available to the caregiver 
and subject for the entire duration of the study.

Change 4
The time between Visit 2 (Test Dose) and Visit 3 (Randomization was clarified. Visit 3 is to 
occur within 24 hours to 28 days of Visit 2. The time between Visit 2 and Visit 3 may be 
extended, the extension must be approved by the Sponsor or CRO designee.

The Brief Smell Identification Test (B-SIT) will be conducted to assess olfactory 
function. The B-SIT is a brief 12-item, self-administered microencapsulated odorant test 
for measuring olfactory function. 
The B-SIT will be conducted at Visit 2 (pre-dose only), Visit 3, and the Final or ET Visit, 
except in cases where obtaining this information is not feasible or appropriate, as 
determined by the investigator. In addition, the B-SIT will be performed only if a 
validated version in the appropriate language is available.
10.5.4 Safety Analyses
B-SIT: For olfactory examination, the B-SIT scores and changes from baseline will be 
presented and plotted by visits. Further analysis adjusted by exposure and time may be 
conducted. Details will be included in the SAP.

Upsher-Smith Laboratories, Inc.
ITI conducted an initial phase I clinical trial (MZ0714) investigating the safety, 
bioavailability, PK, and pharmacodynamic (PD) properties of USL261 entitled “A single-
dose, open-label, five-way crossover, randomized, bioavailability and pharmacodynamic 
study comparing intranasal midazolam administration to intravenous midazolam 
administration in healthy human volunteers.”  Safety, bioavailability, PK, and PD 
parameters for 3 doses of USL261 (2.5 mg, 5.0 mg, and 7.5 mg in 0.1 mL) were compared 
with administration of IV-approved midazolam sterile injection solution administered IV 
(2.5 mg in 5 mL) and IN (5.0 mg in 1 mL) via a needleless syringe. 
Results suggested that maximum plasma concentration (Cmax) of midazolam was achieved 
in all dose groups within 10 minutes to 15 minutes post-administration.  The Cmax for all 
doses of USL261 were within the range of those achieved following IV and IN administration 
of midazolam sterile injection solution.  USL261 demonstrated linear PK parameters.  The 
absolute bioavailability of all USL261 doses was higher (range: 62% – 73%) than 5.0 mg 
midazolam sterile injection solution administered intranasally (50%). 
Changes in PD measures were dependent on midazolam dose; subjects receiving the highest 
dose of USL261 (7.5 mg) reported the largest changes from baseline for all PD measures 
(Stanford Sleepiness Scale, Digit-Symbol Substitution Task, Observers Assessment of 
Alertness/Sedation [OAA/S]).  Route of administration (IV compared with IN) had a 
significant effect on the PD of midazolam.  For example, the maximal sedation effects for all 
IN midazolam formulations were observed between 45 minutes – 1 hour post-dose; however, 
maximal sedation occurred within 15 minutes in subjects administered IV midazolam.  It is 
important to note that no significant differences in PD parameters were reported between 
IN treatments. 
Overall, the proportion of subjects who experienced treatment-emergent adverse events 
(TEAEs) did not increase with ascending doses of IN midazolam.  No TEAEs were reported 
after administration of 2.5 mg IV midazolam.  All TEAEs were mild in intensity, and the 
majority of TEAEs (95.7%) was considered related to study drug.  No serious adverse events

(SAEs) or deaths were reported, and no subject discontinued due to a TEAE.  Overall, the 
most common drug-related TEAEs (reported by ≥10% of subjects) were increased nasal 
discomfort (84%), throat irritation (84%), increased lacrimation (76%), dysgeusia (72%), 
headache (20%), cough (12%), and rhinorrhea (12%).  These TEAEs were only observed 
when midazolam was administered intranasally (IV or IN formulations), which suggests that 
they were related to route of administration. 
A second phase I clinical trial (MZ0815) also investigated the safety, tolerability, PK, and PD 
characteristics of USL261 but in adult and adolescent epilepsy patients rather than healthy 
volunteers.  MZ0815 is a multicenter, in-patient study that evaluated an ascending single-
dose and 2-dose administration of USL261 (2.5 mg, 5.0 mg, and 7.5 mg) given at 2 study visits 
separated by ≥ 3 days.  USL261 was absorbed rapidly (approximately 13 to 20 minutes after 
a single dose; approximately 20 to 30 minutes after the 2-dose regimen) and the midazolam 
Cmax, AUC0-t, and AUC0-∞ general increased with total dose. Midazolam Cmax was lower 
in adolescents as compared to adults. The mean t1/2 following the 2-dose regimen of USL261 
ranged from 2.75 to 4.39 hours. 
USL261 was deemed safe when administered at doses of 2.5 mg to 15.0 mg (total dose) to 
adolescent and adult epilepsy patients who were taking concomitant antiepileptic drugs 
(AEDs).  Of the 90 enrolled subjects, 88 (98%) experienced at least 1 TEAE.  No deaths or 
SAEs were reported, and no study subject prematurely discontinued due to intolerable 
adverse events AEs.  Most TEAEs were mild to moderate in severity and deemed probably 
related to study drug.  The most frequently-reported TEAEs (reported by ≥10% of subjects) 
associated with the study drug were dysgeusia (86%), oropharyngeal pain (57%), rhinalgia 
(31%), and burning sensation (11%).  One subject, who was administered a total dose of 12.5 
mg USL261, experienced moderate hypoxia approximately 90 minutes after administration 
of the second dose; however, the event was transient and not associated with sedation, 
hypoventilation, or changes in vital signs.
USL has completed the clinical conduct of a third Phase I clinical trial (P261-201) entitled

(USL261) in Adult Subjects with Epilepsy on Stable Antiepileptic Drug Regimens”.  This 
was a single-center, in-patient trial investigating the safety, tolerability, PK, and PD of 
escalating single- and two-dose regimens of USL261 compared to placebo in adult subjects 
with epilepsy.  Subjects were assigned sequentially to 1 of 4 cohorts to receive either USL261 
(10.0 mg, 15.0 mg, 17.5 mg, or 20.0 mg) or placebo at two dosing visits separated by ≥ 3 days.  
Each subject received USL261 or placebo at Visit 2.  At Visit 3, each subject received the 
same total dose as he/she received at Visit 2 administered as a divided dose.  The results of 
this study are pending.
USL has completed the clinical conduct of a fourth Phase I clinical trial (P261-102) entitled 
“A Randomized, Investigator and Subject Blind, Sponsor Open, Phase 1 Study of the Safety, 
Tolerability, Pharmacokinetics and Pharmacodynamics of Intranasal Midazolam (USL261) 
in Healthy Geriatric and Non-Geriatric Subjects”.  This was a single-center trial 
investigating the safety, tolerability, PK, and PD of single 2.5 mg and 5.0 mg doses of USL261 
in generally healthy geriatric and non-geriatric subjects.  Enrollment was stratified into non-
geriatric (18 – 40 years old, inclusive) and geriatric (≥ 65 years old) groups such that there 
were 12 subjects in the non-geriatric range and 18 subjects in the geriatric range.  Subjects 
were randomly assigned to receive single doses of both 2.5 mg and 5.0 mg USL261 in a 2x2 
crossover fashion with a washout period of 4 – 10 days between dosing.  Preliminary results 
indicate that although systemic exposures after administration of IN USL261 were 
approximately 20-45% higher in the geriatric group compared to non-geriatric volunteers, 
maximum and overall sedation effect was comparable, and no increase in moderate or severe 
AEs was observed for the geriatric group.

administration in healthy human volunteers.”  Safety, bioavailability, PK, and PD 
parameters for 3 doses of USL261 (2.5 mg, 5.0 mg, and 7.5 mg in 0.1 mL) were compared 
with administration of IV-approved midazolam sterile injection solution administered IV 
(2.5 mg in 5 mL) and IN (5.0 mg in 1 mL) via a needleless syringe.  
Results suggested that maximum plasma concentration (Cmax) of midazolam was achieved 
in all dose groups within 10 minutes to 15 minutes post-administration.  The Cmax for all 
doses of USL261 were within the range of those achieved following IV and IN administration 
of midazolam sterile injection solution.  USL261 demonstrated linear PK parameters.  The 
absolute bioavailability of all USL261 doses was higher (range:  62% – 73%) than 5.0 mg 
midazolam sterile injection solution administered intranasally (50%). 
Changes in PD measures were dependent on midazolam dose; subjects receiving the highest 
dose of USL261 (7.5 mg) reported the largest changes from baseline for all PD measures 
(Stanford Sleepiness Scale, Digit-Symbol Substitution Task, Observers Assessment of 
Alertness/Sedation [OAA/S]).  Route of administration (IV compared with IN) had a 
significant effect on the PD of midazolam.  For example, the maximal sedation effects for all 
IN midazolam formulations were observed between 45 minutes – 1 hour post-dose; however, 
maximal sedation occurred within 15 minutes in subjects administered IV midazolam.  It is 
important to note that no significant differences in PD parameters were reported between 
IN treatments. 
Overall, the proportion of subjects who experienced treatment-emergent adverse events 
(TEAEs) did not increase with ascending doses of IN midazolam.  No TEAEs were reported 
after administration of 2.5 mg IV midazolam.  All TEAEs were mild in intensity and the 
majority of TEAEs (95.7%) were considered related to study drug.  No serious adverse 
events (SAEs) or deaths were reported, and no subject discontinued due to a TEAE.  Overall,

1.3.1.2 Study MZ0815
A second phase I clinical trial (MZ0815) also investigated the safety, tolerability, PK, and PD 
characteristics of USL261 but in adult and adolescent epilepsy patients rather than healthy 
volunteers.  MZ0815 is a multicenter, in-patient study that evaluated an ascending single-
dose and 2-dose administration of USL261 (2.5 mg, 5.0 mg, and 7.5 mg) given at 2 study visits 
separated by ≥ 3 days.  USL261 was absorbed rapidly (approximately 13 minutes to 20 
minutes after a single dose; approximately 20 to 30 minutes after the 2-dose regimen) and 
the midazolam Cmax, area under the plasma concentration time curve from time 0 to time 
of last measurable concentration (AUC0-t), and area under the plasma concentration time 
curve from time 0 extrapolated to infinity (AUC0-∞) generally increased with total dose.  
Midazolam Cmax was lower in adolescents as compared to adults. The mean t1/2 ranged 
from 2.75 to 4.39 hours.
USL261 was deemed safe when administered at doses of 2.5 mg to 15.0 mg (total dose) to 
adolescent and adult epilepsy patients who were taking concomitant AEDs.  Of the 90 
enrolled subjects, 88 (98%) experienced at least 1 TEAE.  No deaths or SAEs were reported, 
and no study subject prematurely discontinued due to intolerable AEs.  Most TEAEs were 
mild to moderate in intensity and deemed to be probably related to study drug.  The most 
frequently-reported TEAEs (reported by ≥10% of subjects) associated with study drug were 
dysgeusia (86%), oropharyngeal pain (57%), rhinalgia (31%), and burning sensation (11%).

hypoxia approximately 90 minutes after administration of the second dose; however, the 
event was transient and not associated with sedation, hypoventilation, or changes in vital

≥ 3 days.  Each subject received USL261 or placebo at Visit 2.  At Visit 3, each subject 
received the same total dose as he/she received at Visit 2 administered as a divided dose.  
USL261 was absorbed rapidly (approximately 9 minutes to 19 minutes after a single dose; 
approximately 19 to 22 minutes after the two-dose regimen). Following either single dose or 
repeat dose administration, PK parameters for both MZ and 1-OH MZ were similar across 
cohorts and did not exhibit dose dependent changes. Exposure to MZ and 1-OH MZ (as 
indicated by Cmax and AUC parameters) was not dose proportional following single dose or 
repeat dose administration of 10.0 mg to 20.0 mg. Effects of USL261 on sedation and 
psychomotor performance were transient following single and repeat dose administration 
and were consistent across USL261 doses. Consistent with PK results, no dose response was 
observed in SSS or OAA/S Sum and Composite scores or their corresponding PD parameters 
from 10.0 to 20.0 mg USL261 following either single or repeat dose administration.
USL261 was generally safe and well-tolerated following single- or repeat-dose administration 
up to the maximum evaluated total dose level of 20 mg in adult subjects with epilepsy taking 
concomitant AEDs. In total, 58 subjects (96.7%) reported 179 TEAEs. All of the reported 
TEAEs were considered mild in severity with the majority (96.0%) were considered 
“probably related” to study drug. Treatment-emergent AEs reported in ≥20% of subjects in 
any group were nasal discomfort and throat irritation, which occurred in 96% of subjects 
administered MDZ NS. However, there was no clear dose relationship and these events also 
occurred frequently in placebo subjects. Nasal mucosal disorder, headache, dysgeusia, and 
hiccups were also common TEAEs, occurring in ≥10% MDZ NS subjects.
1.3.1.4 Study P261-102
Study P261-102 was a single-center trial investigating the safety, tolerability, PK, and PD of

4 – 10 days between dosing.  Mean systemic exposure (AUC) and peak plasma concentrations 
(Cmax) of MDZ were 20–45% higher in the geriatric subjects compared with nongeriatric 
subjects. Geriatric subjects exhibited greater cognitive effects than nongeriatric subjects, 
whereas maximum and overall sedation effects were comparable between the two groups.
Of the 30 enrolled subjects, 26 subjects (87%) reported at least one TEAE during the study 
with more geriatric subjects reporting a TEAE than younger subjects. All reported TEAEs 
(n=115) were considered mild in severity; most (91.3%) were considered “probably related” 
to the study drug. No SAEs or deaths were reported, and no subject discontinued study 
participation due to a TEAE. Although there were some differences between the 2.5 mg and 
5.0 mg doses with regard to the incidence of the more frequently reported AEs, there did not 
appear to be a consistent association with dose.

INTRODUCTION
Acute repetitive seizures and seizure clusters occur in a subset of epilepsy patients. Seizure 
clusters have distinguishable characteristics that are easily recognized by patients, caregivers, 
and physicians and include a consistent onset (auras, prodrome) that may be indicative of 
convulsive or non-convulsive symptoms. Although patients typically recover between seizures, 
these seizure can last anywhere from minutes to hours.1 When a cluster of seizures occurs
outside a hospital, the patient must often be transported to an acute care facility so medical 
personnel can administer intravenous (IV) therapy to stop the seizure(s).2
The primary goals of seizure cluster treatment are seizure cessation and prevention of seizure 
recurrence.1 Acute benzodiazepine treatment is effective for seizure control and often results in 
rapid seizure cluster termination; however, most treatment options rely on intervention by 
emergency medical personnel and, therefore, delay treatment while the patient is transported to a 
medical facility.3 The development of an easily administered outpatient treatment of seizure 
clusters may reduce emergency medical intervention and decrease seizure cluster duration.
This statistical analysis plan covers the detailed procedures for performing statistical analyses 
and producing tables, listings, and figures of the Phase 3 study Protocol P261-401 (Fifth Issue, 
Amendment 4, 20 May 2015).

STUDY DESIGN
2.1.
General Study Design and Plan
This is a Phase 3 multicenter study, with 2 distinct phases and 4 study center visits as depicted in
Figure 1. The first phase is the Test-Dose Phase where subjects will receive 2 doses of open-
label 5.0 mg USL261 10 minutes apart at the study center. The Test-Dose Phase is designed to 
assess the safety, tolerability and pharmacokinetics of USL261 in a monitored setting and 
provide the caregivers with training on the study procedures. The Test-Dose Phase will be 
followed by an outpatient, double-blind, placebo-controlled, parallel-group phase, referred to as 
the Comparative Phase. In the Comparative Phase, all subjects will be randomized 2:1 to receive 
5.0 mg USL261 or placebo. The subject’s caregiver will administer the double-blind study drug 
at the time of a seizure cluster that meets the study criteria, according to the subject’s 
individualized Patient Management Plan (PMP). The double-blind dose of study medication may 
be followed by an open-label single dose of 5.0 mg USL261 if any of the following occurs:

The treated seizure cluster has not terminated within 10 minutes after the initial drug 
administration or 

Another seizure occurs between 10 minutes and 6 hours after administration of the 
study drug, and the subject does not have <8 breaths per minute, does not require 
emergency rescue treatment and assisted breathing intubation, and does not have 
excessive uncharacteristic sedation 
Anytime between 24 to 120 hours after study drug administration, subjects and caregivers will 
return to the study center for a post-dose study visit (Visit 4).

A maximum of approximately 350 subjects, aged 12 years and older, with a documented history 
of seizure clusters and on a stable AED regimen (no change in type[s] of drug) will be enrolled 
in the Test-Dose Phase in order to achieve a maximum of 240 subjects completing the 
Comparative Phase. Before any subject continues to the Comparative Phase, safety data from at 
least 25 subjects in the Test-Dose Phase will be reviewed by an independent Data and Safety 
Monitoring Board (DSMB). Enrollment will temporarily halt once approximately 25 subjects 
complete the Test-Dose Phase, to allow the DSMB to review the safety data. If the safety data 
from this initial cohort supports continuation of the trial according to the DSMB, enrollment into 
the Test-Dose Phase will resume and the initial 25 subjects will proceed to the Comparative 
Phase. All subsequent subjects will progress directly from Test-Dose Phase to the Comparative 
Phase.
A classic group sequential design, with 3 interim analyses and a maximum sample size of 240 
subjects who have completed the Comparative Phase is utilized in order to reach sufficient 
overall power (approximately 90%) for this study with possible study stopping at interims for 
efficacy or futility. In this group sequential design, interim analyses will occur after 132, 165, 
and 204 subjects have completed the Comparative Phase.
Figure 1 shows the overall study scheme with regard to screening, Test-Dose Phase, and 
Comparative Phase.

2.1.1.
Screening
After subjects and caregivers have provided informed consent (and assent, where appropriate), 
subjects will undergo screening procedures at Visit 1 (see Table 1). At Visit 1, training will be 
provided to the caregivers for self-study, which will be completed at or before Visit 2. The 
screening period (time between Visit 1 and 2) will be a maximum of 28 days. The screening 
period may be extended in certain cases; however, the extension of the screening period must be 
approved by the Sponsor or CRO designee. If a screening period extension is granted for a given 
subject, that subject will have to undergo repeat screening laboratory and ECG assessments 
within 28 days before Visit 2.

2.1.2.
Test-Dose Phase
The Test-Dose Phase, which occurs at Visit 2, will take place at the study center under the 
supervision of the study investigator within 28 days of Visit 1. The investigator, or other 
qualified study personnel, will review, assess, and (if needed) re-instruct subjects and caregivers 
on the information provided in the self-study training. Caregivers must demonstrate hands-on 
competence in performing timed assessments and recording information in the Subject 
Workbook, as well as airway management techniques. 
Subjects who meet eligibility criteria at Visit 2 will receive a test dose of 5.0 mg USL261 
administered by a member of the study center personnel followed by a second dose of 5.0 mg 
USL261 10 minutes later administered by the caregiver under the supervision of a member of the 
study center personnel. Caregivers and study center personnel will monitor the subject during the 
observation period for at least 4 hours after the test doses are administered and the assessments 
outlined in Table 1 will be performed. After 132 subjects have completed the Comparative 
Phase, for all new test dosed subjects, caregivers and study center personnel will monitor the 
subject during the observation period for at least 1 hour after test dose administration. A subject 
who experiences signs or symptoms at Visit 2 that are concerning in the investigator’s judgment 
or are exclusionary per exclusion criterion number 22 must be monitored until resolved or longer 
as deemed appropriate by the investigator.
At least one study center personnel who is trained and qualified to perform airway assessment 
and management, including endotracheal intubation (or local country /site equivalent) and 
Advanced Cardiac Life Support (ACLS) (or local country/site equivalent), will be available at 
the site for the entire observation period following the administration of the first test dose.
2.1.3.
Comparative Phase
Subjects and caregivers will return to the study center for Visit 3 within 24 hours to 28 days of 
Visit 2 (unless DSMB review of first 25 subjects is not yet completed). At Visit 3, the 
investigator, or other qualified study personnel, will review, assess, and (if needed) re-instruct 
caregivers on the information provided in the self-study training. Before subjects are 
randomized, caregivers must have demonstrated hands-on competence in administering the study 
drug, performing timed respiration rate measurements and recording them in the practice Subject 
Worksheet, as well as airway management techniques.
If the subject continues to meet eligibility criteria at Visit 3, he/she will be randomized to receive 
either USL261 5.0 mg or placebo. Caregivers will receive a study materials kit, which includes 
the Subject Workbook, the subject’s Patient Management Plan (PMP), and the study drug kit. 
The PMP will specify the criteria for seizure cluster recognition, the procedure for contacting the 
central study nurse hotline after study drug administration, the requirements for administering a 
second dose of study drug (active USL261), and a rescue protocol individualized for the subject.
During the Comparative Phase, caregivers will administer the double-blind study medication at 
the time of a seizure cluster that meets study criteria (according to the subject’s individualized 
PMP) and call the central study nurse hotline as soon as possible following study drug 
administration. If the treated seizure has not terminated within 10 minutes after the initial drug 
administration or another seizure occurs between 10 minutes and 6 hours after administration of 
the study drug, and the subject does not have < 8 breaths per minute, does not require emergency

rescue treatment with assisted breathing or intubation, and does not have excessive 
uncharacteristic sedation (as defined by the investigator in the PMP), the second dose of study 
drug (ie, 5.0 mg dose of USL261) may be administered. If the second dose of study drug is 
administered, the caregiver will again call the central study nurse hotline as soon as possible after 
its administration. The caregiver will monitor the subject after study drug administration to 
record safety and efficacy measurements.
If the subject encounters persistent seizure cluster activity or seizure recurrence (as defined in the 
subject’s PMP), has < 8 breaths per minute, or is excessively and uncharacteristically sedated, 
caregivers will follow the rescue protocol in the subject’s PMP. The subject’s rescue protocol 
will outline rescue instructions individualized for the subject, including when and how to contact 
EMS (or local equivalent).
Subjects and caregivers will return to the study center 24 to 120 hours after study drug 
administration for Visit 4. Subjects who are prematurely discontinued from study participation or 
terminate their participation should return to the study center for Visit 4 (Early Termination).
The subject or caregiver will report to the investigator (or his/her designee) as soon as possible
any significant medical event (including events that are life-threatening or that result in death, 
hospitalization or prolonged hospitalization, persistent or significant disability, or incapacity of 
the subject) that occurs to the subject from the time written informed consent is obtained until 
completion of the final study visit (Visit 4 [Post-Dose Assessment or ET]) or 7 days after last 
administration of study drug , whichever is later. The subject or caregiver may also call the 
central study nurse hotline at any time during the study for help or advice regarding study 
procedures.
This study will be conducted in accordance with International Conference on Harmonization 
(ICH) E6, Guidelines for Good Clinical Practice (GCP) and applicable regulatory requirements 
including the US Code of Federal Regulations dealing with clinical studies (21 Code of Federal 
Regulations [CFR] including § 50 and 56 concerning informed consent and Institutional Review 
Board [IRB] regulations, respectively).
2.2.
Randomization and Method of Treatment Assignment 
A stratified, blocked randomization schema will be generated by an unblinded statistician and 
used to assign subjects to treatment. Treatment assignments will be assigned and kept strictly 
confidential by the Interactive Response Technology (IRT) System. Randomization will be 
stratified by age (< 18 vs. ≥ 18). Within each stratum, subjects will be randomized in a 2:1 ratio 
of USL261 5.0 mg nasal spray (active) or matching placebo nasal spray using an appropriate 
randomly permuted block.
Subjects who meet eligibility requirements at Visit 3 will be randomized to treatment. At the 
time of randomization, subjects will be assigned unique subject identification numbers. Numbers 
will be assigned in consecutive increasing order without replacement or reuse of any assigned 
number. The study will be double-blinded to the treatment group assignment accessible only to 
authorized persons per sponsor’s (or designee’s) Standard Operating Procedures (SOPs) until the 
time of unblinding.

ANALYSIS POPULATIONS
4.1.
Screened Population
The Screened Population includes all subjects who signed an Informed Consent Form (ICF) or 
assent form.
4.2.
Safety Population
The Safety Population includes all subjects who received at least 1 dose of study drug even if 
they were not randomized. Therefore, this population includes all treated subjects, including 
those who terminate following the test dose (Visit 2), but before randomization (Visit 3), as well 
as subjects who are randomized.
4.3.
Randomized Population 
The Randomized Population includes all subjects who are randomized to receive double-blind 
treatment. The Randomized Population is also the Intent-to-treat (ITT) Population.

4.4.
Randomized Safety Population
The Randomized Safety Population (RSAF) is the group of subjects who are randomized and 
receive at least one dose of double-blind study drug. If a subject received the wrong treatment in 
the double-blind period or until discontinuation, the safety data for that subject will be 
summarized under the actual treatment group received. The demographic, baseline 
characteristics and safety data will be summarized under the following treatment groups:

USL261 5 mg: USL261 group who received only the first dose of double-blind study 
drug

USL261 5 + 5 mg: USL261 group who received the first dose of double-blind study 
drug and the second dose of open-label USL261

Placebo: Placebo group who received only the first dose of double-blind study drug

Placebo + USL261 5 mg: Placebo group who received the first dose of double-blind 
study drug and the second dose of open-label USL261
4.5.
Modified Intent-to-Treat Population (mITT)
The mITT Population includes all subjects in the Randomized Population who received at least 1 
dose of study drug during the Comparative Phase, who had post-treatment efficacy assessment
(ie, with any seizure diary data). This mITT definition was chosen because Randomized subjects 
may be discontinued from the study prior to treatment in the Comparative Phase. Following the 
intent-to-treat principle, all efficacy analyses will be conducted using the mITT Population,
analyzed according to the randomized treatment assignment. The potential biases arising from 
excluding randomized subjects who did not receive study medication are negligible since 
exclusion is not influenced by knowledge of whether being assigned to USL261 or placebo.
4.6.
Per Protocol Population 
The Per Protocol Population includes all subjects in the mITT Population who did not 
discontinue study participation or have any excludable protocol deviations (see Section 7.2).
All protocol deviations will be reviewed in a blinded manor prior to DB lock and it will be 
determined prior to DB lock if a patient should be excluded from the Per Protocol population. 
The Per Protocol population will be used for supportive analysis to assess robustness of the 
primary analysis.
4.7.
Pharmacokinetic Population 
The PK Population includes all subjects who received a test dose of USL261 in the Test-Dose 
Phase, have at least one quantifiable post-dose concentration and have no excludable protocol 
deviations (see Section 7.2). All protocol deviations will be reviewed in a blinded manor prior to 
DB lock and it will be determined prior to DB lock if a patient should be excluded from the PK 
population.

GENERAL STATISTICAL CONSIDERATIONS
5.1.
Level of Significance
Statistical comparisons will be performed using two-sided tests at the =0.05 significance level
except as discussed in the interim analysis section.
To control Type I error for the primary and secondary efficacy endpoints, a statistical gate-
keeping procedure will be applied to control for multiplicity. The primary and secondary efficacy 
endpoints will be tested individually using the following hierarchical procedure:
First step: The proportion of subjects that are classified as Treatment Success during the 
Comparative Phase (two sided p-value) will be determined.
To proceed to the next step in the hierarchy, the previous step must be statistically significant (ie,
two sided p-value is significant favoring USL261).
Second step: Time to next seizure following first dose of study drug (p-value from the log-rank 
test) will be determined.
Third step: The proportion of subjects with recurrence of seizure(s) beginning at 10 minutes after 
to 4 hours following the first dose of study drug.
All null hypotheses will be defined as no treatment difference.
5.2.
Handling of Missing Data
Any specific imputation procedures for missing or incomplete data will be discussed in the 
section describing analytic methods for the efficacy/safety variable in question. Unless otherwise 
stated, observed data will be presented in tables and listings without imputation of missing 
values. 
AEs with non-complete start dates and complete stop dates after the first double-blind study drug 
administration will be considered TEAEs during the Test Dose Phase if:

Time is missing and the date is equal to or after the date of test-dose administration 
and is equal to or before the date of the first double-blind study drug administration;

Day and month are missing and the year is equal to or after the year of test-dose
administration but is equal to or before the year of the first double-blind study drug
administration;

Day is missing and the year is equal to or after the year of test-dose administration but 
is equal to or before the year of the first double-blind study drug administration;

Day is missing, the year is equal to the year of test-dose administration, and the 
month is equal to or after the month of test-dose administration but is equal to or 
before the month of the first double-blind study drug administration;

Year is missing;

Complete date is missing.

AEs with partial start dates and complete stop dates after administration of the first double-blind 
study drug will be considered TEAEs during the Comparative Phase if:

Time is missing and the date is after the date of the first double-blind study drug 
administration;

Day and month are missing and the year is after the year of the first double-blind 
study drug administration;

Day is missing and the year is after the year of the first double-blind study drug 
administration;

Day is missing, the year is equal to the year of the first double-blind study drug
administration, and the month is after the month of the first double-blind study drug 
administration.
Missing AE relationships will be presented as ‘related’ in tables but missing in listings. Missing 
AE intensity will be considered as ‘severe’ in tables but will be reported as missing in listings.
Medications with non-complete dates will be considered concomitant if partial dates show that
medications were taken between the day of first dose of study drug at Visit 2 and the end of 
study. Medications will be considered prior if partial dates show that medications were taken 
within 30 days prior to the first dose of study drug at Visit 2. Medications can be categorized as 
both prior and concomitant.
5.3.
Interim Analyses
Three interim analyses will be conducted to evaluate the treatment success rate for possible early 
stopping for success or futility. The interim analyses will occur after 132, 165, and 204 subjects 
complete the Comparative Phase (ie, subjects have received at least 1 dose of study drug during 
the Comparative Phase). All interim analyses will be performed on the mITT population, ie,
subjects that are randomized and experience a cluster seizure event during the comparative 
phase. Subjects lost to follow-up or with missing primary outcome information will be 
considered treatment failures.
Treatment success is defined in Section 7.6.1.1.
5.3.1.
Early Success
Early success will be declared as shown in Table 2. A group sequential design is used to allow 
for multiple interim analyses for efficacy, yet control the type I error rate at 2.5%. The Lan-
DeMets spending function approximation of the Pocock boundary, is used for the efficacy 
boundary. The critical values for this efficacy boundary were obtained using R package gsDesign 
(version 2.8-8).
At each interim analysis, a one-sided Fisher’s Exact test on the two proportions will be 
performed and compared to the Lan-DeMets Pocock approximation boundary critical values. For 
the three planned interim analyses and the final analysis, the critical values are presented in
Table 2.

Early Futility
Also at each of the pre-specified interim analyses (N=132, 165, 204), the predictive probability 
of success at the maximum sample size is computed (futility is not applicable to the final analysis 
at 240 subjects). The predictive probability calculation begins by assuming non-informative 
uniform prior distributions, Beta(1,1), on the treatment success rates for the placebo/control arm 
(pC) and the probability of treatment success in the treatment arm (pT), and computing the 
posterior distribution with the currently available data. The predictive distribution of the final 
data assuming the maximal sample size of N=240 is then computed. The number of future 
treatment successes for each arm has a Beta-Binomial distribution which is then added to the 
fixed number of current treatment successes in each arm. We may then compute the predictive 
probability that a trial success is reached at N=240 subjects. If this predictive probability is less 
than 10%, the trial is stopped for futility. Note that the success boundaries are computed 
assuming no futility stopping, and thus controls type I error regardless of the method used for 
futility stopping.
5.3.3.
Early Termination not related to Success or Futility 
If the trial has not crossed a boundary for early success or early futility and yet is stopped early 
before reaching the pre-specified maximum sample size of 240 subjects, the final analysis will be 
conducted with the enrolled patients in the mITT population. The p-value required for study 
success will remain as the p-value required at the final analysis according to the pre-specified 
Lan-DeMets Pocock boundary as if the trial had performed all planned interim analyses and 
continued to the maximum sample size. Therefore the p-value required for success will be 
p=0.0085 as described in Table 2 (Section 5.3.1).
5.3.4.
Logistical details for interim analyses
The interim analyses will be conducted by an unblinded statistician and reviewed by an 
unblinded interim analysis monitoring committee (IAMC), both independent of the sponsor. The 
IAMC will consist of two individuals with adaptive design expertise to ensure the pre-specified 
adaptations are performed as planned, and to react to any unanticipated issues. The IAMC will 
be independent of the DSMB. IAMC membership, responsibilities, timelines, and 
communication channels will be clearly specified in a charter. In particular, the IAMC 
communication channels with the sponsor will be limited to maintain the blind of the sponsor 
study team in order to minimize the chance of operational bias. To this end, the IAMC will 
inform senior management first of the decision to continue the trial or stop according to the

statistical analysis plan. The senior management will in turn inform the team to continue or not 
to continue the study only with no further information on the interim analysis.

The data collected from the unscheduled visits are excluded from the by visit summary analysis. 
However, when defining baseline for each assessment, the data collected from the unscheduled 
visits are still included.

DESIGN OPERATING CHARACTERISTICS
6.1.
Simulation Scenarios
The estimated placebo treatment success rate is 0.40. The study is powered under the hypothesis 
that the USL261 treatment will lead to a clinically meaningful odds ratio of 2.9. With these 
assumptions, the sample size of 240 subjects who have completed the Comparative Phase (160 
USL261/80 placebo) is sufficient to obtain approximately 90% power.
We examined a range of odds ratios/treatment success rates for placebo treatment success rates 
of 40% and performed 10,000 simulations to determine the power and average sample size (type 
I error is controlled analytically through the group sequential design). Simulations were 
performed using R version 3.1.0. For a given set of data we computed the success and futility 
criteria analytically. To simulate an individual trial, placebo and treatment data were simulated 
from the appropriate Binomial distributions (using the required sample sizes and placebo and 
treatment rates) and compared to the success and futility bounds. Trials that continued at an 
interim had additional data simulated, and so on until the trial reached completion. After

simulating 10,000 trials, the overall power, expected sample size, and other operating 
characteristics were computed by taking the observed mean values throughout the simulations.
6.2.
Operating Characteristics
Assuming treatment success rates of 0.40 for the placebo arm, and Odds Ratio of 2.9, the power 
of this design is approximately 90% while maintaining at most 2.5% type I error. The expected 
(average) sample size will be approximately 150. 
7.
STATISTICAL ANALYSIS
Categorical variables will be summarized using counts and percentages. Continuous variables, 
including the change from baseline, will be summarized using descriptive statistics [n, mean, 
standard deviation (SD), minimum, median, maximum]. For modeling results, least squares 
means and standard errors will be presented.
Unless otherwise stated, all summaries will be presented by treatment group (USL261 or 
Placebo).
The Test Dose Phase is defined as the period of time from the date of first dose of study drug 
administration at Visit 2 up to, but not including, the date of randomization. The Comparative 
Phase is defined as the period of time from the date of randomization to the date of the last 
assessment in the study.

will not necessarily be excluded from the analysis populations. The excludable protocol 
deviations will be classified by the sponsor for each population. Protocol deviation categories 
will be presented in a data listing and summarized using counts and percentages by treatment 
group. Major protocol deviations may include, but are not limited to: 

Failure to obtain informed consent

Failure to report a Serious Adverse Event (SAE)

Enrolling patients outside of inclusion/exclusion criteria

Drug dispensing/dosing errors
7.3.
Demographics and Baseline Characteristics
Demographics and baseline characteristics will be presented for the Safety Population and 
repeated for the Randomized Safety and mITT Populations. Subject demographics include age, 
gender, weight, height, BMI, race, clinical site region, and ethnicity. Weight recorded in pounds 
will be converted to kilograms, and height recorded in inches will be converted to centimeters.
Weight will also be categorized and summarized based on median for safety population
(<median weight and ≥ median weight).
Age (years) will be calculated as the integer number of years between date of birth and informed 
consent date. If the informed consent data is missing then the assent date will be used instead.
In addition subject age (years) will be categorized as follows:

< 18 years

≥18 - < 65 years

≥65 years
Subject baseline characteristics will include: IQ (if available), epilepsy type, developmentally 
delayed status, EEG history, CT scan and/or MRI history, previous and current seizure types, 
seizure etiology including primary cause of epilepsy, and seizure cluster episode history. For 
seizure cluster episodes, if duration are collected in free-text which covers a period of time, 
average of the upper bound and the lower bound will be used for the analysis.
Subject demographics will additionally be presented for the mITT Population by the Treatment 
Success status of their first double-blind dose of study drug (see Section 7.6.1 for the definition 
of treatment success). These data presentations will include columns for “Treatment Success of 
first dose” and “Not Treatment Success of first dose” for each treatment group.
Comparability of treatment groups will be evaluated using descriptive statistics.
7.4.
Medical and Surgical History
Medical and surgical history will be coded using the MedDRA coding dictionary version 14.1.
Coded medical history terms will be summarized by MedDRA system organ class (SOC) and 
preferred term (PT) for the Safety, Randomized Safety and mITT Populations. SOC will be 
sorted alphabetically and then preferred term will be sorted in order of frequency of the total

column within each SOC. At each level of summarization, a subject will be counted only once 
for each medical and surgical history he/she has within that level. Subject listings of coded 
medical history terms will be provided.
For subjects who were rescreened after study drug exposure and have two subject identifiers, all 
medical and surgical history data will be combined into one subject identifier.
7.5.
Prior and Concomitant Medications
Prior medications are defined as medications taken within 30 days prior to the first dose of study 
drug at Visit 2. Concomitant medication is defined as any medication taken between the day of 
first dose of study drug at Visit 2 and the end of study.
The World Health Organization Drug Dictionary (WHO Drug) of version December 2011 will 
be used to classify prior and concomitant by therapeutic class and preferred name based on ATC 
code level 4. Medication start and end dates will be compared with the start date of study drug 
and classified as per Table 4. 
In case of partial or missing dates, comparisons will be made based on the level of detail 
available. For example, if start date of study drug administration is 04Jan2013, and a medication 
has a start date of Jan2013 but missing date the medication will be classified as concomitant.

Prior/Concomitant medications excluding AEDs, prior/concomitant AEDs, prior/concomitant 
AEDs used for epilepsy, and prior/concomitant AEDs used for indications other than epilepsy 
will be summarized separately and similar to concomitant medications. AEDs will be further 
classified as enzyme-inducing and non-inducing AEDs.
Listings will be provided for prior/concomitant medications and prior/concomitant AEDs for all 
subjects. AEDs collected from AED page on CRF will be presumed to have ‘Epilepsy’ as 
indication. AEDs collected from concomitant medication page will be listed by indication 
captured on CRF.
For subjects who were rescreened after study drug exposure and have two subject identifiers, all 
medication data will be combined into one subject identifier.
7.6.
Analyses of Efficacy Endpoints
Information recorded by the caregiver in the Subject Workbook will be used for analysis of the 
primary, secondary, and exploratory efficacy endpoints. Any seizures occurring within 24 hours 
after administration of study drug will be recorded. Subjects without any recurrent seizures 
recorded with a start time >10 minutes after administration of study drug will be considered 
seizure-free in all analyses.
The following covariates will be used in the analyses of efficacy endpoints, where specified:

Age (< 18 years, 18 - <65 years, ≥65 years)

Sex (male/female)

Weight (kg)

BMI standardized categories (underweight/normal [<25], overweight [≥25-<30], and 
obese 1-3 categories combined [≥30]) 

Geographic region of clinical site (North America and similar [this includes USA, 
Canada, Australia and New Zealand], Eastern Europe [Hungary, Poland, Ukraine], 
and Western Europe [Spain, Germany, Italy, and Israel])

Enzyme-inducing AEDs used within 14 days before the study drug administration 
(see Appendix 2) vs others
Additional covariates may also be explored.
7.6.1.
Primary Efficacy Endpoint
All statistical analyses of the primary efficacy endpoint will be conducted for the mITT 
Population and analyzed as described in Section 5.3. The primary efficacy endpoint analyses will 
also be conducted on the Per Protocol Population as supportive analyses. The following null (Ho) 
and alternative (Ha) hypotheses will be evaluated:

Ho: The proportion of subjects who meet the criteria for Treatment Success is not 
different between the USL261 and the placebo groups in the Comparative Phase;

Ha: The proportion of subjects who meet the criteria for Treatment Success is 
different between the USL261 and the placebo groups in the Comparative Phase.

Treatment Success is a composite measure of efficacy that will be assessed based upon the first 
seizure cluster treated with study drug during the Comparative Phase. Treatment Success is 
defined as achieving the following:

Termination of seizure(s) within 10 minutes after the double-blind study drug 
administration, and

No recurrence of seizure(s) beginning 10 minutes after study drug administration to 6 
hours after the double-blind study drug administration
7.6.1.1.
Derivation of Treatment Success Endpoint
Treatment Success will be determined based on data reported in the CRFs and derived 
programmatically. An imputation will be conducted first for the seizure start time and end time. 
If the end time of a seizure is missing, impute the end time to the next subsequent seizure’s start 
time if the two aforementioned seizures occrurred within the same date; otherwise, the missing 
end time will be imputed as 23:59.
If the start time of a seizure is missing, impute the start time to the previous seizure’s end time if 
the two aforementioned seizures occurred within the same date; otherwise, the missing start time 
will be imputed as 00:00.
There are three components to be assessed in the programmatic derivation:
1. Termination of seizure(s) within 10 minutes: The initial seizure stopped within (≤) 10 
minutes from the time of dosing and any subsequent seizures also stopped within 10 
minutes of dosing. Data used in this derivation includes the time of first dose as recorded 
on the “Study Drug Administration (First Dose)” CRF, and seizure data recorded on the 
“Report All Seizures for 24 Hours” and the “Seizure Diary” CRFs. 
2. No recurrence of seizure(s) beginning 10 minutes after study drug administration to 6 
hours after study drug administration. The times of reported seizures will be used to 
assess if there are any seizures with start time from >10 minutes up to (≤) 6 hours after 
the first dose of study drug. Data used in this derivation includes seizure data recorded on 
the “Report All Seizures for 24 Hours” CRF.
3. No second dose given within 6 hours of the first dose of study drug administration as 
receiving the second dose within (≤) 6 hours confounds the efficacy evaluation of the first 
dose. Data used in this derivation include the time of second dose as recorded on the 
“Study Drug Administration (Second Dose)” CRF.
Subjects who meet all three of these components will be defined as a “Treatment Success.” If a 
subject does not meet all three of these components, (which may or may not be due to missing 
data), they will be defined as “Not a Treatment Success.”
Possible scenarios for seizure data start and stop times within the 6 hour period following the 
first dose of study drug are displayed below in Figure 3, along with the treatment success 
endpoint derivation (assuming no second dose was given):

Possible Scenarios for Seizure Data Start and Stop Times Within the 6 Hour 
Period Following the First Dose of Study Drug Are Displayed Below, Along 
with the Treatment Success Endpoint Derivation (Assuming No Second Dose 
was given)
7.6.1.2.
Analysis of the Primary Endpoint
Treatment Success will be analyzed by Fisher’s Exact test. The 95% confidence intervals (CIs), 
using normal approximation around the proportions, will be presented. In addition, each 
component (seizure termination and recurrence) of treatment success will be summarized by 
treatment group. Chi-squared test will be performed as a sensitivity analysis. Results from both 
tests (Fisher and Chi-squared) will be presented together. In addition, the Cochran-Mantel-
Haenszel (CMH) test, stratified by age (< 18 years, ≥18 - <65 years, ≥65 years) will be used to 
analyze Treatment Success.
Subjects who do not have sufficient available data to confirm whether they can be classified
either as “Treatment Success” or as “Not a Treatment Success” as described in Section 7.6.1.1
are considered to have missing data. For the primary analysis of Treatment Success, subjects 
with missing data impacting the Treatment Success endpoint described above will be considered 
as “Not a Treatment Success.” 
Similarly, for each component of the Treatment Success endpoint (seizure termination and 
recurrence), when available data do not allow to determine the classification, subjects with

missing data will be considered as having an unfavorable outcome for the corresponding 
component. Sensitivity analysis will be conducted for the Treatment Success endpoint in order to 
assess robustness of study conclusions to missing data using a tipping point approach.4 This
approach will provide the results for the analysis of the primary endpoint under an exhaustive set 
of possible outcomes among subjects with missing data in the USL261 and Placebo treatment 
groups. Clinical interpretation of the plausibility of different combination of outcomes will be 
provided in the Clinical Study Report. The tipping point analysis will be conducted as follows. 
Let n1m and n2m be the number of subjects with missing data in the USL261 and Placebo 
treatment groups respectively.
Step 1: Let k1=0. 
Step 2: Let k2=0. 
Step 3: Repeat the analysis of the primary endpoint as described above by considering k1
subjects from the USL261 treatment group as “Not a Treatment Success” and (n1m - k1) subjects 
as “Treatment Success,” while considering k2 subjects from the Placebo treatment group as “Not 
a Treatment Success” and (n2m – k2) subjects as “Treatment Success.”
Step 4: Let k2= k2+1. Repeat Steps 3 - 4 while k2≤n2m.
Step 5: Let k1= k1+1. Repeat Steps 2 - 5 while k1≤n1m.
The results of the analysis for each possible combination of outcomes for subjects with missing 
data (k1 and k2) will be presented in a table. Additionally, a graph will be produced presenting 
the number of subjects with missing data considered as “Not a Treatment Success” on the X and 
Y axes for the USL261 and Placebo treatment groups respectively, and dots marking the 
combinations of X- and Y-axis values for which the null hypothesis was not rejected in favor of 
the USL261 treatment.
An additional exploratory logistic regression on Treatment Success will include the covariates 
specified in Section 7.6. A backward selection of covariates will be used to obtain the final 
model. All covariates with a p>0.10 will be dropped from the model. The covariates remaining in 
the final model that are identified as having significant association with the outcome (p<0.05) 
may be explored in a subgroup analysis. The odds ratio between USL261 and Placebo and its 
associated 95% confidence intervals will be reported. This analysis will be conducted 
considering all subjects with missing data as “Not a Treatment Success”, similar to the primary 
analysis.
7.6.2.
Secondary Efficacy Endpoints
All secondary efficacy analyses will be based on the mITT population. Multiplicity adjustments 
are described in Section 5.1).
7.6.2.1.
Proportion of Subjects with Recurrence of Seizure(s) Beginning 10 Minutes after 
Administration of Double-Blind Study Drug to 4 Hours after Double-Blind 
Study Drug Administration
The proportion of subjects with recurrence of seizure(s) recorded in the diary with start time >10 
minutes and ≤4 hours after the administration of double-blind study drug will be analyzed using 
Fisher’s Exact test. The 95% CIs will be presented for the proportion. In addition, Chi-squared

test will be performed as a sensitivity analysis. Subjects who have been administered the second 
dose of study drug (ie, 5.0 mg dose of USL261) within 4 hours of double-blind study drug 
administration will be derived as if they had a recurrence of seizure. Subjects who do not have a 
seizure recorded, or whose first seizure occurs >4 hours after study drug administration, will be 
counted as not having a seizure.
7.6.2.2.
Time to Next Seizure with a Start Time >10 Minutes after Double-Blind Study 
Drug Administration
Kaplan-Meier estimates will be used to summarize the time-to-next seizure after double-blind 
study drug administration. Subjects who do not have another seizure before the end of the 24-
hour observation period, and have not been administered the second dose of study drug (ie, 5.0 
mg dose of USL261) will be censored at the end of the observation period. Subjects administered 
the second dose of study drug (ie, 5.0 mg dose of USL261) who did not have a seizure before the 
administration of the second dose will be censored at the time of the second dose (5.0 mg 
USL261) administration. The time-to-next seizure percentiles (defined based on the data) with 
associated 95% CIs will be displayed. The probabilities of experiencing the next seizure after 
double-blind study drug administration at each hour with associated standard error and 95% 
confidence intervals will be presented. The log-rank test will be used to compare the time to next 
seizure after double-blind study drug administration between treatment groups. In addition, the 
hazard ratio for treatment (USL261: placebo) and its 95% CI will be calculated from a Cox 
proportional hazards model. Kaplan-Meier curves by treatment group will also be presented.
Additional analysis will be conducted based on a different censoring method that subjects 
administered the second dose of study drug (ie, 5.0 mg dose of USL261) who did not have a 
seizure before the administration of the second dose will be considered as events (failure).
The Cox proportional hazards regression model will be used to evaluate the difference between
treatment groups adjusting for the covariates specified in Section 7.6. Interactions between 
treatment and each covariate will be evaluated at the 0.10 significance level; if not significant,
they will be removed from the final model.
7.6.3.
Exploratory Efficacy Analyses
Exploratory efficacy analyses will be conducted using the mITT population. All tests performed 
will test a two-sided hypothesis of no difference between groups at a significance level of 0.05
for all exploratory outcome measures.
7.6.3.1.
Proportion of Subjects with Recurrence of Seizure(s) Beginning 10 Minutes after 
Study Drug Administration to 24 Hours after Study Drug Administration
The proportion of subjects with recurrence of seizure(s) with a start time >10 minutes and ≤24 
hours after study drug administration will be analyzed using Fisher’s Exact Test. The 95% CIs 
will be presented for the proportion. In addition, Chi-squared test will be performed as a 
sensitivity analysis. Subjects who do not have a seizure recorded with a start time >10 minutes 
and ≤24 hours after the administration of double-blind study drug will be counted as not having a 
seizure. Subjects who have been administered the second dose of study drug (ie, 5.0 mg dose of 
USL261) within 24 hours will be assumed to have had a seizure.

7.6.3.2.
Return to Full Baseline Functionality within 24 Hours after Study Drug 
Administration (as determined by the caregiver)
The proportion of subjects who have documented return to full baseline functionality will be 
analyzed using Fisher’s Exact Test. The 95% CIs will be presented for the proportion. In 
addition, Chi-squared test will be performed as a sensitivity analysis. Subjects who did not have 
a time of return to full baseline functionality recorded within 24 hours of study drug 
administration or who have been administered the second dose of study drug (ie, 5.0 mg dose of 
USL261) prior to returning to full functionality will be counted as not having returned to full 
baseline functionality.
Kaplan-Meier estimates will be used to summarize the time to return to full baseline 
functionality. Subjects who do not have a time of return to full baseline functionality recorded 
within 24 hours of study drug administration and have not been administered the second dose of 
study drug (ie, 5.0 mg dose of USL261) will be censored at the end of the observation period.
Subjects who were administered the second dose of study drug (ie, 5.0 mg dose of USL261) 
prior to returning to full functionality will be censored at the time that the second dose (USL261) 
was administered. The probabilities of return to full baseline functionality after double-blind 
study drug administration at each hour with associated standard error and 95% confidence 
intervals will be presented. The log-rank test will be used to compare the time to return to full 
baseline functionality between treatment groups. In addition, the hazard ratio for treatment 
(USL261: placebo) and its 95% CI will be calculated from a Cox proportional hazards model.
Kaplan-Meier curves by treatment group will also be presented.
The Cox proportional hazards regression model will be used to evaluate the difference between 
treatment groups adjusting for the covariates specified in Section 7.6. Interactions between 
treatment and each covariate will be evaluated at the 0.10 significance level; if not significant,
they will be removed from the final model.
7.6.3.3.
Analyses for Subjects Receiving 2 Doses of Study Drug
Data from subjects randomized to USL261 and placebo who received the first dose of double-
blind study drug and the second dose of open-label study drug (ie, 5.0 mg dose of USL261) will 
be used for the analyses of subjects receiving 2 doses of study drug.
7.6.3.3.1. Treatment Success of the Second Dose of Study Drug (5.0 mg of USL261)
Treatment Success of the second dose for subjects receiving the second dose of study drug (ie, 
5.0 mg of USL261) will be presented for each treatment group. For the active group, this 
represents two doses of 5.0 mg of USL261. The placebo group has received one dose of 5.0 mg 
of USL261 (preceded by a dose of placebo). Since the administration of the second dose is not a 
randomized treatment, the analysis includes only subjects whose seizure was not stopped by the 
first dose and were given the second dose of study drug (ie, 5.0 mg of USL261).
For this analysis, Treatment Success of the second dose is defined as achieving the following:

Termination of seizure(s) within 10 minutes after the second dose of study drug (5.0 
mg of USL261)


No recurrence of seizure(s) beginning 10 minutes after administration of the second 
dose of study drug (ie, 5.0 mg of USL261) to 6 hours after the second dose of study 
drug (5.0 mg of USL261)
Subjects whose Subject Workbook indicates seizure termination within 10 minutes of the second 
dose and who have no seizures recorded with start time > 10 minutes and < 6 hours after the 
second dose of study drug will be considered a Treatment Success of the second dose. Subjects 
who do not meet either of these criteria will not be considered a Treatment Success of the second 
dose. Similar derivation rules as used for the primary endpoint will be used for defining 
Treatment Success of the second dose, with the exception of not including the rule pertaining to 
the second dose.
Number and percentage will be presented for Treatment Success of the second dose and each 
component (seizure termination and recurrence) for subjects who received two doses of study 
drug. The 95% CIs for the proportions will also be presented.
7.6.3.3.2. Additional Second Dose Data Presentations / Analyses
A summary of subjects receiving the second dose of study drug by randomized treatment arm 
will be presented. In addition to the total number of subjects receiving the second dose, counts of 
subjects receiving the second dose in specific time categories post first dose (0 to <10 minutes, 
>=10 to ≤20 minutes, >20 minutes to ≤1 hr, >1 hr to 6 hrs, and >6 hrs) will also be presented.
Kaplan-Meier estimates will be used to summarize the time-to-second dose. Subjects who do not 
receive the second dose of study drug (ie, 5.0 mg dose of USL261) within 6 hours of the initial 
study drug administration will be censored at the end of this 6 hour period. The time-to-second 
dose percentiles (defined based on the data) with associated 95% CIs will be displayed. Kaplan-
Meier curves by treatment group will also be presented.
As an additional exploratory analysis, a logistic regression with response treatment success of the 
second dose will be examined including time from first dose to second dose as a continuous 
covariate with treatment as an effect.
Kaplan-Meier estimates will also be used to summarize the time-to-next seizure following the 
second dose. Subjects who do not have another seizure before the end of the 24-hour observation 
period following the second dose of study drug (ie, 5.0 mg dose of USL261) will be censored at 
the end of this observation period. The time-to-next seizure following the second dose 
percentiles (defined based on the data) with associated 95% CIs will be displayed. The 
probabilities of experiencing the next seizure following the second dose at each hour with 
associated standard error and 95% confidence intervals will be presented. Kaplan-Meier curves 
by treatment group will also be presented.
7.6.3.4.
Treatment Success of all Dose of Study Drug
Treatment Success of all doses will be assessed based upon the Treatment Success of the first 
dose and Treatment Success of the second dose taken within 6 hours after first dose during the 
Comparative Phase. If the second dose taken later than 6 hours after first dose, then treatment 
success of all doses will only be based on the result of treatment success for the first dose.
The same analysis as described in Section 7.6.3.3.1 (Treatment Success of the Second Dose of 
Study Drug) will be performed for treatment success of all doses.

Subject and Caregiver Outcome Assessments
7.6.3.5.1. SF-12v2
The SF-12v2 is a 12-item questionnaire which will be administered to both the subject and 
caregiver at Visits 2 and 4. All analyses will be presented separately for the subject and 
caregiver. Eight domains make up the SF-12v2: physical functioning, role-physical, bodily pain, 
general health, vitality, social functioning, role-emotional, and mental health. In addition, the 
physical functioning, role-physical, bodily pain, and general health domains will be combined to 
obtain the Physical Health Component Score (PCS); the vitality, social functioning, role-
emotional, and mental health domains will be combined to obtain the Mental Health Component 
Score (MCS). The scores for each domain, the PCS and the MCS range from 0 to 100, where 
zero indicates the lowest level of health by the scales and 100 indicates the highest level of 
health.5
Summary scores for PCS and MCS for each patient will be computed using published 
algorithms.4 Each summary measure is scored and standardized using a t-score transformation, 
such that a higher score represents better health status, with a mean score of 50 and a standard 
deviation of 10 in the general population.6 Missing data on the SF-12v2 will be handled as 
follows: domain scores will not be calculated for domains in which data are missing.
Subsequently, component scores in which domain scores are missing will not be calculated. 
Summarization and analysis of SF-12v2 data will be performed for the mITT and the 
Randomized Safety population. The domain and component scores will be presented for Visit 2 
(baseline) and Visit 4/ET, including change from baseline. For each domain and component 
score a paired t-test will be used to assess the within-group mean change from baseline. An 
analysis of covariance (ANCOVA), with treatment and baseline as covariates, will be used for 
between-group comparison of change from baseline for the domain and component scores. 
7.6.3.5.2. Treatment Satisfaction Questionnaire for Medication (TSQM)
The TSQM is a 14- item questionnaire that will be administered to the subject. The four TSQM 
scale scores calculated from the questionnaire are: effectiveness, side-effects, convenience, and 
global satisfaction. The TSQM scale scores are computed by adding the items loading on each 
factor. The lowest possible score is subtracted from the composite score and divided by the 
greatest possible score minus the lowest possible score. This will provide a transformed score 
between 0 and 1 that is then multiplied by 100. If more than one item is missing from each scale, 
the scale will not be calculated. Calculation of each scale score is provided below.7
Effectiveness
([Q1 + Q2 + Q3) – 3]/18) * 100
If one item is missing then, ([Qx + Qy – 2]/12) * 100 where x and y = 1, 2, or 3, with 
x≠y.
Side-Effects
If Q4 is ‘No’ then score = 100
Else, ([Q5 + Q6 + Q7 + Q8 – 4]/16) * 100

If one item is missing then, ([Qx + Qy + Qz – 3]/12) * 100 where x, y, and z = 5, 6, 7, or 
8, with x≠y≠z.
Convenience
([Q9 + Q10 + Q11) – 3]/18) * 100
If one item is missing then, ([Qx + Qy – 2]/12) * 100 where x and y = 9, 10, or 11.
Global Satisfaction
([Q12 + Q13 + Q14) – 3]/14) * 100
If one item is missing then, ([Qx + Qy – 2]/8) * 100 where x and y = 12, 13, or 14.
Summarization and analysis of TSQM data will be performed for the mITT population. The 4 
scale scores will be presented for Visit 2 (baseline) and Visit 4/ET, including change from 
baseline. For each score a paired t-test will be used to assess the within-group mean change from 
baseline. An analysis of covariance (ANCOVA), with treatment and baseline as covariates will 
be used for between-group comparison of change from baseline. 
7.6.3.5.3. Intranasal Therapy Impact Questionnaire (ITIQ)
The ITIQ is a two item questionnaire that is completed by both the subject and caregiver at Visit 
4/ET. The level of anxiety change since subject received intranasal therapy is a scale with a 
range from -7 to 7, and confidence about travelling having a spray the subject can take with them 
is a scale from 1 to 5. The change in level of anxiety since subject received intranasal therapy 
will be compared between treatment groups using the t-test. The chi-square will be used to 
compare treatment groups for confidence about travelling having a spray the subject can take 
with them.
7.7.
Safety Analyses
All safety analyses will be presented by phase of the study based on the Safety Population and 
Randomized Safety Population, unless otherwise specified.
7.7.1.
Adverse Events (AEs)
Adverse events will be coded using the Medical Dictionary for Regulatory Activities (MedDRA) 
Version 16.1. Coding includes SOC and preferred term (PT). All verbatim descriptions and 
coded terms will be listed for all AEs.
For subjects who screen fail prior to the start of the Test Dose Phase for the reason of an adverse 
event, the event will be recorded on the Screening Failure Log.
7.7.1.1.
Pre-treatment AEs 
Pre-treatment AEs will be defined as any AE that started before the study drug administration at 
Visit 2. Pre-treatment AEs will be flagged out in a listing named as ‘Adverse Events’.
7.7.1.2.
Treatment-emergent AEs (TEAEs)
TEAEs will be categorized as TEAEs during the Test Dose Phase and TEAEs during the

The following AEs will be defined as TEAEs during the Test Dose Phase:

AEs with onset on or after study drug administration at Visit 2 and up to first dose of
study drug in Comparative Phase;

AEs that started prior to study drug administration at Visit 2, but worsened in severity 
following study drug administration at Visit 2 up to first dose of study drug in 
Comparative Phase.
The following AEs will be defined as TEAEs during the Comparative Phase:

AEs with onset on or after the first dose of study drug in Comparative Phase;

AEs that started prior to study drug administration at Visit 2, but worsened in severity 
following the first dose of study drug in Comparative Phase.
All AEs will be listed by subject and by MedDRA SOC and PT.
The number of events and the frequency and percentage of subjects with TEAEs/SAEs will be 
summarized for the Safety Population during the Test Dose Phase and for the Randomized 
Safety Population during the Comparative Phase. An overall summary of all AEs for Screened 
Population will also be presented. Summary tables of TEAEs and SAEs will be presented by 
SOC and PT. At each summary level, a subject will be counted only once for each AE he/she 
experiences within that level, regardless of how many occurrences of that AE that subject 
experienced. The percentage of subjects having had at least one TEAE/SAE at each level will be 
calculated. All the TEAE analysis will also be repeated for the subset of all TEAEs that started 
within two days of study drug administration.
Tabular summaries will include all TEAEs, TEAEs by age group (< 18 years, ≥18 - <65 years, 
≥65 years), TEAEs by severity (mild, moderate, severe), TEAEs by relationship to study drug,
TEAEs of interests, serious TEAEs (SAEs) including SAEs leading to permanent discontinuation
or death, SAEs by severity, and SAEs by relationship to study drug. If there are any deaths while 
on study, they will be presented in a listing that includes the AE leading to death, demographic 
data, details of study treatment, and relationship of the AE leading to death to the study drug. In 
addition, all TEAEs, SAEs, and AEs leading to discontinuation will be flagged out in the listing 
of Adverse Events. 
In instances where a subject may have multiple TEAEs with differing levels of severity or 
relatedness, the most severe or most related event, respectively, will be reported for the severity 
and relatedness tables. For the purpose of analysis, TEAEs with a reported relatedness of
“Related”, ”Possibly Related”, “Unlikely Related”, or missing the relationship will be classified 
as related to study drug. TEAEs assessed as “Not Related” will be classified as not related to 
study drug. TEAEs with missing severity will be presented as severe in the tables but will be 
listed as missing.
The following AEs of special interest (AESIs) will be summarized by AESI category:

Taste and smell disorders

Acute central respiratory depression


Observer’s Assessment of Alertness/Sedation (OAA/S)
The OAA/S scale is a validated qualitative categorical measure of sedation.8 The OAA/S Scale is 
composed of four assessment categories: responsiveness, speech, facial expression, eyes.
Responsiveness has possible scores of 1, 2, 3, 4, or 5; speech has scores of 2, 3, 4, or 5; and 
facial expression and eyes have scores of 3, 4, or 5. The OAA/S Scale is scored in two ways as 
described below. Descriptive statistics and graphical presentations will be used to present results 
by time point at Visit 2 for the Safety Population.
7.7.2.1.
Composite Score
The composite score has a range between 1 (deep sleep) and 5 (alert); the lowest level checked 
by the study center personnel in any one of the four assessments will be analyzed. The composite 
score will be set to missing if all 4 of the assessment categories are missing.
Number of subjects with an OAA/S composite score of 1 at Visit 2 will be presented by time 
point and overall total.

The sum score is the sum of the 4 assessments. If one of the assessment categories is missing, the 
sum score will be set to missing.
Summaries for the composite score and sum score will be based on the calculation specified 
above. However, an imputation approach on each domain score will be employed for the 
derivation of pharmacodynamic parameters described in the next section. Specifically, for each 
individual domain score, if a subject who has completely missing data at all timepoints for a 
single domain, the median domain score of all available data from all other subjects at each 
timepoint will be used as the domain score for this subject. For subjects with complete missing 
scores for two or more domains at all timepoints, each domain score will be treated as missing at 
all timepoints and OAA/S sum and composite scores will not be calculated.
7.7.2.3.
Pharmacodynamic (PD) Parameters
The following PD parameters will be calculated by subject using non-compartmental methods 
for the OAA/S composite score and sum score following midazolam dosing:

Table 6:
Pharmacodynamic Parameters
Parameter
Definition
AUEC0-t
Area under the effect (AUEC) versus time curve, from time 0 to the time of last 
measurable value. Calculated using the linear trapezoidal method.
AUEC0-x
Area under the effect (AUEC) versus time curve, calculated using the linear 
trapezoidal method from time 0 to the x time, where x =1, 2 and 4 hours.
Emax
Maximum observed PD effect. Note – For OAA/S sum and composite scores, 
this will represent the lowest observed score (as lower scores indicate greater 
sedation)
Teffect
Time to Peak “Emax“ Effect
Among these parameters, the calculated OAA/S sum score and composite score will be used for 
calculating the unadjusted Emax. The Emax will also be adjusted by using change from baseline 
values of OAA/S composite score and sum score. For parameters AUEC0-t , AUEC0-x (x=1, 2, 4), 
the calculation will be based on the change from baseline values of OAA/S composite score and 
sum score.
Actual time will be used for AUEC calculation. If actual time for pre-dose values is before the 
Test dose, 0 will be used for time point calculation. If equal to or greater than 50% domain data 
for a subject is missing, then all their AUEC values (including AUEC0-last, AUEC0-1hr, AUEC0-2hr 
and AUEC0-4hr) will be treated as missing. If less than 50% domain data for a subject is missing, 
then last observation carried forward approach will be used to impute all missing time points 
after the last non-missing time point.
Individual PD parameter values will be listed and descriptive statistics will be used to present PD 
parameters at Visit 2 for the Safety Population.
7.7.3.
Requirement for Unscheduled ER or EMS Visit
The number and percent of subjects requiring an unscheduled ER or EMS visit within 24 hours 
after study drug administration in the Comparative Phase will be compared between treatment 
groups for the Randomized Safety Population using Fisher’s Exact Test. In addition, Chi-squared 
test will be performed as a sensitivity analysis.
7.7.4.
Brief Smell Identification Test (B-SIT; United States only)
For olfactory examination, the B-SIT final scores and changes from baseline will be presented 
and plotted by visits. Baseline value is defined as the Visit 2 (pre-dose) value. An analysis of 
covariance (ANCOVA), with treatment and baseline as covariates, will be used for between-
group comparison of change from baseline for the B-SIT final scores.
7.7.5.
Columbia-Suicide Severity Rating Scale (C-SSRS)
The C-SSRS is collected referencing two time points for suicidal ideation (lifetime, past 6 
months) and two time points for suicidal behavior (lifetime, past 5 years) at Visit 1 (screening).
For all analyses the ‘lifetime’ time point will be used for Visit 1 assessments. In addition, a 
‘Since Last Visit’ version will be administered at Visits 2, 3 and 4/ET.

Each suicidal ideation severity rating will range from 0 (no ideation present) to 5 (active ideation 
with plan of intent). Descriptive statistics will be presented for suicidal ideation severity rating at 
each visit by treatment group. 
Descriptive statistics will also be presented for suicidal ideation intensity at each visit by 
treatment group. The five intensity items (frequency, duration, controllability, deterrents, and 
reason for ideation) will be combined to create a total, sum score ranging between 0 and 25. If 
the subject did not have any suicidal ideation, the total score will be 0. If the subject had suicidal 
ideation and if one intensity item is missing, the total score will not be calculated.

Laboratory Parameters
Clinical laboratory parameters for serum chemistry, hematology, and urinalysis will be 
summarized descriptively for each study visit. Mean and mean change from baseline values will 
be presented for each study visit. Change from baseline will be calculated as the Visit 4/ET 
measurement minus the baseline measurement. If either the baseline or Visit 4/ET value is 
missing, the observation will not be included in the change from baseline summary. The last 
value at post-baseline visits will be used for summaries.
Each laboratory result will be classified as low (L), normal (N), and high (H) at each visit 
according to the laboratory-supplied normal range. The shift from baseline will be presented.
Potentially clinically significant (PCS) laboratory abnormalities will be identified using 
standardized criteria in Appendix 1 prior to database lock and will be presented by for each 
treatment group. Additional displays of PCS may be presented.
Baseline values are the last available values collected prior to the test-dose.
7.7.8.
Vital Signs and Oxygen Saturation
Vital signs (systolic and diastolic blood pressure, pulse, respiration rate, temperature) will be 
summarized descriptively for each study visit and time point and presented graphically 
(excluding temperature) for each Visit 2 time point. Mean and mean change from baseline values 
will be presented for each study visit and time point, excluding temperature. Change from 
baseline will be calculated as post-baseline measurement minus baseline measurement. If either 
the baseline or post-baseline value is missing, the observation will not be included in the change 
from baseline summary. Baseline values are the last available values before Test-Dose 
administration.

Electrocardiogram (ECG)
Electrocardiogram (ECG) parameters (heart rate, PR interval, RR interval, QRS interval, QT 
interval, and QTc interval) will be summarized descriptively for each scheduled visit and time 
point collected for the Safety Population. Mean and mean change from baseline values at Visit 2
will be presented. Change from baseline will be calculated as post-baseline measurement minus 
baseline measurement. If either the baseline or post-baseline value is missing, the observation 
will not be included in the change from baseline summary. In addition, counts and percentages 
for ECG diagnosis (normal or abnormal) at each study visit and time point will also be presented.

OTHER PLANNED ANALYSES
8.1.
Pharmacokinetic (PK) Analyses
Pharmacokinetic parameters for individual plasma concentrations will be calculated using a 
standard non-compartmental approach using appropriate validated PK software (WinNonlin 
Enterprise version 5.2 or higher). The following PK parameters of midazolam and 1-
hydroxymidazolam will be calculated from data obtained for the PK Population:

AUC0-last – the area under the plasma concentration-time curve from time 0 to the last 
measurable concentration. Estimation by the linear-up/log-down trapezoidal method 
is preferred.

AUC0-x – the area under the plasma concentration-time curve from time 0 to time x, 
where x =1, 2 and 4 hours.

Cmax – the maximum plasma concentration

tmax – the time to reach the maximum plasma concentration


tlag – the time before the first measurable plasma concentration
Due to the limited length of the PK sampling schedule (out to a maximum of 4 hrs post dose), it 
is unlikely that sufficient samples will be available for estimation of the terminal rate constant 
(λz). Thus, λz and associated PK parameters (viz. terminal half-life, AUC0-∞, CL/F and Vz/F) will 
not be calculated a priori. If supported by the data, additional PK parameters may be calculated 
after discussion with the Sponsor.
Pre-dose concentration values reported as below the limit of quantification (BLQ) and missing 
pre-dose values will be treated as “0” and listed as BLQ. A series of BLQ values that includes 
the pre-dose time point will also be treated as “0” and listed as BLQ. All other BLQ values will 
be set to missing. Actual sampling times will be used in the calculations of PK parameters.
With the exception of tmax and tlag, descriptive statistics by treatment group will include the 
number of observations (N), mean, standard deviation (SD), coefficient of variation (CV%),
geometric mean, and geometric CV%, as well as median, minimum, and maximum for the PK
variables. Summary statistics for tmax and tlag will be limited to N, minimum, maximum and 
median. In addition, summary of PK variables stratified by AED inducer status as well as figures 
of Midazolam and 1-OH Midazolam concentrations on linear and semi-log scales will also be 
presented.
A covariate analysis that examines the effect of continuous (age, weight) and, if supported, 
categorical (gender, race, and age group [adult vs adolescent]) demographic variables on the PK 
parameters may be conducted.
8.2.
Pharmacokinetic/Pharmacodynamic Variables and Analyses
Correlations between PK/PD data from the test dose may be evaluated. If conducted, the PK/PD 
analysis may include correlating the plasma midazolam plus 1-hydroxymidazolam 
concentrations to respiratory rate, BP, HR, O2 saturation, and/or sedation based on OAA/S
scores. Regression analysis may be used describe the PK/PD relationship, if one exists. For those 
PD measurements found to correlate to plasma concentrations, the influence of covariates such 
as gender, AED inducer status, weight, BMI, race, and age group may be explored.

CHANGES TO THE PLANNED ANALYSIS
Since the last submission of the P261-401 Statistical Analysis Plan (v2.4) to the FDA (S-0150, 
03 March 2015), the following changes were made to the plan (v2.5-v2.9):

The Brief Smell Identification Test (B-SIT) was added to the list of safety objectives. 
The plan for analysis of B-SIT data was also added. These changes were made to 
reflect the changes implemented in Protocol Amendment 4, 20 May 2015.

The procedures to be completed at Visits 1, 4, and on the monthly telephone follow-
up calls between Visit 3 and Visit 4 were updated to add collection of the number of 
calls to EMS and ER visits for a seizure cluster or other seizure emergency prior to 
Visit 1 and during the study. This change was made to reflect the changes 
implemented in Protocol Amendment 4, 20 May 2015.


The process for reviewing CSR Reportable protocol deviations and exclusions prior 
to database lock was clarified to determine if any subject should be excluded from 
specific analysis populations. 

The subgroup analyses of the primary and secondary endpoints were further clarified 
to examine consistency as follows:

The time-frame around the use of enzyme-inducing AEDs was defined as within 
14 days before study drug administration. Population PK modeling of deinduction 
times for strong CYP3A4 inducers, including carbamazepine, indicates a 
deinduction half-life following discontinuation of approximately 3 – 4 days with 
return to baseline function occurring within approximately 14 days following 
discontinuation of dosing. Based on these estimates, a subject should be classified 
as “induced” if they have received an enzyme-inducing AED ≤ 14 days prior to 
administration of USL261.

The weight will be categorized based on the median weight for the safety 
population (< median weight and ≥ median weight). This categorization based on 
the median weight was chosen to be representative of the population studied.

The BMI will be categorized as underweight/normal (< 25), overweight (≥25 to 
<30), and obese 1-3 categories combined (≥30). This categorization was based on 
standard BMI categories.

The subgroups frequency of seizure clusters and benzodiazepine use was removed 
as these subgroups are based on historic data and may not represent the seizure 
cluster frequency or benzodiazepine use relative to administration of study drug in 
the Comparative Phase.

The subgroups seizure types (generalized and focal) and seizure etiology were 
removed.

For subjects who were rescreened and underwent two Test Dose Visits, baseline will 
be defined as the last available values before the later Test Dose administration. This 
clarification was provided to prespecify how baseline is defined in a unique situation.

An additional exploratory efficacy analysis, “treatment success of all doses of study 
drug,” was included in the plan. This exploratory analysis was added to assess the 
Treatment Success of the first dose and Treatment Success of the second dose (taken 
within 6 hours) during the Comparative Phase.

The definition of a treatment-emergent adverse event (TEAE) in the Test Dose Phase 
and in the Comparative Phase was clarified. This clarification was made to clearly 
define the phase in which TEAEs will be reported. However, it does not impact the 
definition of a TEAE or the total TEAEs reported.

The AEs of special interest (AESI) and abuse-related AEs were defined.

Additional detail for the calculation of the following PD parameters: OAA/S sum 
score, AUEC0-t, AUEC0-x, and Emax was added.

An early study termination analysis unrelated to study success or futility was added in 
the event that the trial has not crossed a boundary for early success or early futility 
and yet is stopped early before reaching the pre-specified maximum sample size of 
240 subjects.

Washout period required for deinduction following discontinuation of inducing AEDs.
Population PK modeling of deinduction times for strong CYP3A4 inducers, including 
carbamazepine, indicates a deinduction half-life following discontinuation of approximately 
3-4 days with return to baseline function occurring within approximately 14 days following 
discontinuation of dosing [29-32]. Based on these estimates, a subject should be classified as 
“induced” if they have received an enzyme-inducing AED ≤ 14 days prior to administration of 
USL261.
