PRODUCT QUALITY COMPLAINTS
Investigators are required to report investigational product quality complaints to Shire within 
24 hours. This includes any instances wherein the quality or performance of a Shire product 
(marketed or investigational) does not meet expectations (eg, inadequate or faulty closure, 
product contamination) or that the product did not meet the specifications defined in the 
application for the product (eg, wrong product such that the label and contents are different 
products). The product quality includes quality of the drug delivery device combination product. 
As such device defects should be reported according to the instructions in this section. The 
reporting of product quality occurrences, when the product does not meet specifications, includes 
the reporting of device defects. For instructions on reporting AEs related to product complaints, 
see Section 8.3.

STUDY SYNOPSIS
Protocol number: SHP615-301
Drug: Midazolam hydrochloride oromucosal solution (MHOS/SHP615) 
Title of the study: A Phase 3, Multicenter, Open-label Study to Determine the Efficacy, Safety, and 
Pharmacokinetics of Buccally Administered MHOS/SHP615 in Pediatric Patients with Status Epilepticus 
(Convulsive) in the Hospital or Emergency Room
Number of subjects (total and for each treatment arm): Approximately 25 subjects (minimum 3 subjects per age 
group)
Investigator(s): Multicenter study (in hospital or healthcare settings)
Site(s) and Region(s): Approximately 25 hospitals in Japan
Study period (planned):
September 2017 to August 2019
Clinical phase:
3
Objectives:
Primary: To assess the efficacy of MHOS/SHP615 administered buccally in pediatric patients with status 
epilepticus (convulsive) in a healthcare setting.
Secondary: To assess the safety and pharmacokinetics of MHOS/SHP615 administered buccally to pediatric 
patients with status epilepticus (convulsive) in a healthcare setting.
Rationale: Under the proprietary name BUCCOLAM® MHOS/SHP615 is currently approved for treatment of 
pediatric patients presenting with status epilepticus (SE) in a hospital or emergency room in several European Union 
(EU) countries. The intravenous (IV) formulation of midazolam is currently administered buccally off label for the 
treatment of SE in a healthcare setting in Japan. This study will provide data to support approval and labeling of 
age-based dosing of MHOS/SHP615 for the treatment of SE in Japanese pediatric patients.
Investigational product, dose, and mode of administration:
Midazolam hydrochloride oromucosal solution (MHOS/SHP615) is a clear, colorless, ready-to-use solution 
(containing 5 mg midazolam [as hydrochloride] per mL). MHOS/SHP615 has been specifically developed as a 
single, age-specific, fixed dose (approximately 0.25 to 0.5 mg/kg as midazolam) formulation for buccal 
administration in children.
Each pre-filled dosing syringe is individually packed in a protective plastic tube. 
The four available unit dose packs are:

2.5 mg (yellow label) for children aged 3 months (52 weeks corrected gestational age) to <1 year (and 
weight >5 kg)

5 mg (blue label) for children aged 1 year to <5 years

7.5 mg (purple label) for children aged 5 years to <10 years

10 mg (orange label) for children aged 10 years to <18 years
Methodology: SHP615-301 is a Phase 3, multicenter, interventional, nonrandomized, open-label study of 
MHOS/SHP615 administered buccally to subjects <18 years who present with SE in the healthcare setting. Children 
whose corrected gestational age is 52 weeks (gestational weeks plus the number of weeks after birth) and <18
years, weight >5 kg ,who arrive at the healthcare setting in full seizure, and have not received immediate treatment, 
are eligible to participate in this study providing all inclusion/exclusion criteria are met. The seizure event(s) must 
be accompanied by loss of consciousness and can be either generalized tonic clonic or start focally and then 
generalize.
This study consists of a 24-hour, open-label treatment period followed by a 1-week safety follow-up period. Upon 
entry in the SHP615-301 study, subjects will receive a single open-label MHOS/SHP615 treatment, dosing stratified 
by age (2.5, 5, 7.5, 10 mg buccally).

The efficacy of MHOS/SHP615 in stopping prolonged convulsive seizures will be assessed by measuring the 
percentage of subjects whose initial seizure stops within 10 minutes with a sustained absence of visible seizure 
activity for 30 minutes following a single, age-based dose of MHOS/SHP615. If the seizures have not stopped 
within 10 minutes after a single dose of MHOS/SHP615 the subject will be treated according to participating 
healthcare setting protocol or guideline. The safety and pharmacokinetics of MHOS/SHP615 will also be assessed.
Subjects will be monitored by vital signs, laboratory tests, and ECGs for safety evaluations. All subjects who 
withdraw early or who complete treatment in this study will be followed for 1 week after the dose of SHP615 for 
safety evaluations. 
Inclusion and exclusion criteria:
Inclusion Criteria:
1.
Male and female subjects whose corrected gestational age is ≥52 weeks (gestational weeks plus the number 
of weeks after birth) and <18 years, and weight >5 kg, at the time of investigational product administration.

Efficacy
The primary efficacy endpoint is the response rate, which is defined as the percentage of subjects with therapeutic 
success.

Therapeutic success will be defined as:
o
the cessation of visible seizure activity within 10 minutes, with
o
a sustained absence of visible seizure activity for 30 minutes following a single dose of 
MHOS/SHP615. 
The secondary efficacy endpoints will include:

Percentage of subjects whose seizure event(s) stopped within 10 minutes of a single dose of 
MHOS/SHP615 and who have sustained absence of seizure activity for the following time periods after the 
single dose of MHOS/SHP615:
o
1 h
o
4 h
o
6 h

Time to resolution of seizures (convulsions) 

Time to recovery of consciousness

Percentage of subjects who fail to respond to treatment. 
o
Treatment failure/Nonresponder is defined as continuing seizure activity and/or the need for any 
additional rescue medication according to the participating healthcare setting protocol or 
guideline, 10 minutes after a single dose of MHOS/SHP615.
Safety
The primary safety endpoints will be respiratory depression, which will include the following measures within the 
4 hours after MHOS/SHP615 administration

Persistent decrease in oxygen saturation to <92% measured at 10 minutes, 30 minutes, and 4, 6, and 
24 hours postdose (ie, <92% on room air for 2 minutes or more after dosing while monitoring [per 
healthcare setting protocol and/or the clinical judgment of the physician]).

Increase in respiratory effort such that assisted ventilation is used (bag-valve-mask ventilation or 
endotracheal intubation)


Incidences/monitoring of treatment-emergent adverse events (TEAEs), vital sign measurements, laboratory 
tests, oxygen saturation, and ECG

Occurrence of buccal irritation
Pharmacokinetics (population PK)

Plasma concentrations of midazolam, its active metabolite (1-hydroxymidazolam), and any potential additional 
metabolite(s) will be evaluated. Exploratory evaluation of potential additional metabolite(s) may also be 
performed. PK samples will be collected at 1, 3, and 6 hours (or time of discharge, if earlier than 6 hours) after 
administration of MHOS/SHP615.
Statistical methods
Sample size:  The target sample size (approximately 25 subjects; minimum 3 subjects per age group) is estimated 
based on the expected response rate which is assumed to be 58.5% compared with the threshold of 30% with at least 
80% of statistical power at the 2-sided 5% level.
Efficacy analysis
Efficacy data of the full analysis set (FAS) will be summarized using descriptive statistics. The FAS will include the 
population of subjects with SE who received a single dose of MHOS/SHP615 and have at least 1 assessment of 
therapeutic success performed after the administration of MHOS/SHP615.
The primary efficacy analysis will be conducted on the FAS, by constructing the 2-sided, 95% confidence interval 
(CI) for the percentage of subjects reaching therapeutic success defined as:
o
the cessation of visible seizure activity within 10 minutes, with
o
a sustained absence of visible seizure activity for 30 minutes following a single dose of 
MHOS/SHP615. 
The lower limit of the 95% CI will be compared with the threshold of 30%, which is equivalent to comparing the 
percentage of success to the threshold at the 2-sided 5% level of significance.
Safety analysis
Safety data will be summarized using descriptive statistics on the Safety Set. The Safety Set will include subjects 
who receive a single dose of MHOS/SHP615. TEAEs will be summarized and will include treatment, seriousness, 
and severity. Other TEAE data that will be reported in the listings include treatment, relationship to 
MHOS/SHP615, and the time of event onset.
Other safety data (including vital signs, laboratory tests, ECG findings, aspiration pneumonia, Riker 
Sedation-Agitation Scale, and oxygen saturation) will be summarized.
Population PK analysis
Plasma concentrations of midazolam, its active metabolite (1-hydroxymidazolam), and any potential additional 
metabolites will be evaluated using the Pharmacokinetic Set. The Pharmacokinetic Set will include subjects who 
receive a single dose of MHOS/SHP615 and for whom at least 1 post-dose PK blood sample was collected. 
Pharmacokinetic parameters will be calculated using population PK modeling.

BACKGROUND INFORMATION
1.1
Status Epilepticus
A seizure is defined as a transient occurrence of signs and/or symptoms due to abnormal,
excessive, and synchronous neuronal activity in the brain. Several seizure types can be described,
but they all fall into 1 of 2 classifications:  primary generalized seizures (eg, grand mal, petit mal, 
or absence seizures) and partial (focal) onset seizures (ie, localized). Regardless of seizure type, 
most seizures (>90%) last less than a few minutes (<2 minutes) (Theodore et al., 1983). If 
seizures are prolonged or occur in a series, there is an increased risk of status epilepticus (SE),
which literally means a continuous state of seizure (Epilepsy Foundation, 2015).
SE, a condition resulting either from the failure of the mechanisms responsible for seizure 
termination or from the initiation of mechanisms that lead to abnormally prolonged seizures, is a 
life-threatening neurologic emergency with significant morbidity and mortality. Mortality rates 
are 15% to 20% in adults and 3% to 15% in children. Acute complications result from 
hyperthermia, pulmonary edema, cardiac arrhythmias, and cardiovascular collapse. Long-term 
complications include epilepsy (20% to 40%), encephalopathy (6% to 15%), and focal 
neurologic deficits (9% to 11%). Prompt cessation and rapid control of SE is critical to prevent 
this neurological and systemic pathology (Fountain, 2000).
Convulsive SE (CSE), the most common childhood neurological emergency in developed 
countries, can lead to neurocognitive sequelae and death. History with epilepsy is the strongest 
single risk factor for generalized CSE:  15% to 27% of patients with epilepsy will experience at 
least 1 episode of SE; 25% to 40% of SE occurs in patients with epilepsy.
The term SE includes not only epilepsy, but also status of serial convulsive seizures associated 
with febrile convulsion, encephalitis, and encephalopathy. The International League Against 
Epilepsy (ILAE) defines SE as a seizure lasting longer than a defined period of time or more 
than 1 seizure occurring within a shorter timeframe without return to normalcy between seizures
(ILAE, 1989). More recently, the minimum seizure duration had been defined as 30 minutes 
(Riviello et al., 2006); however, because epileptic discharge longer than 30 minutes has been 
reported to damage the brain, the diagnosis of SE was subsequently updated to a seizure lasting 
longer than either 10 minutes (Treiman et al., 1998) or 5 minutes (Alldredge et al., 2001), at 
which time treatment should be promptly initiated. The urgency to treat this condition, supported 
by evidence that seizures rarely last more than a few minutes, led to implementation of an 
operational definition of early status epilepticus (ESE), or seizures lasting more than 
5 minutes (Dham et al., 2014; Brophy et al., 2012; Lowenstein et al., 1999; Lowenstein, 1999). 
This definition of SE (ie, seizures lasting more than 5 minutes) will be used throughout this 
study. 
Incidence, cause, and prognosis of pediatric SE vary geographically, as well as by different 
socioeconomic conditions, environments, and genetic susceptibility. The incidence of SE is 
bimodally distributed, occurring most frequently during the first year of life and after age 
60 years. Amongst children (<15 years of age), infants <12 months have the highest
incidence and frequency of the disease.

In Japan, annual incidence of SE in children younger than 17 years is 42 cases per 
100,000 persons. In addition to young age, other risk factors include genetic predisposition and 
acquired brain insults (Fountain, 2000; Working Group on Status Epilepticus, 1993; Shinnar et 
al., 1996; Berg et al., 1999).
Left untreated (or undertreated) SE, depending on the type and duration of seizures, can cause 
permanent neurological injury (including neuronal death, neuronal injury, and alteration of 
neuronal networks) or death (Trinka et al., 2015). Therefore, a rapid treatment must be initiated. 
1.2
Current Treatment Options
For an anti-epileptic drug to be effective in SE, it is usually administered intravenously (IV) by 
health professionals to provide quick access to the brain without the risk of serious systemic and 
neurological adverse effects (Sirven and Waterhouse, 2003). Multiple drugs are available; the 
first line treatment is benzodiazepines (eg, diazepam), and midazolam (midazolam is not 
authorized for SE in the United States [US]).
The first-choice medication in Japan for treating SE in pediatric patients without venous access is 
diazepam suppositories administered rectally. Rectal diazepam is the medication most commonly 
used throughout the European Union (EU) in the community setting, and is authorized for this 
indication. Diazepam is effective in 60% to 80% of patients but with a risk of early seizure 
recurrence of up to 30% and respiratory depression (McIntyre et al., 2005). The increase of drug 
concentration in the blood is slow by this route; constipation and bowel movements can interfere 
with absorption of drug (Wilson et al., 2004). Rectal administration can be difficult during 
tonic-clonic seizures. For wheelchair users, it can be challenging to remove clothing and to insert 
the suppository in a convulsing child. Therefore, the rectal route of administration is not always 
practical, socially acceptable, or convenient.
For resistant cases, phenytoin (or fosphenytoin), phenobarbital, and thiopentone are injectable, 
fast-acting drugs that have strong anti-convulsant effects and a positive safety profile. Securing
vascular access in children, however, is generally more difficult and prolongs stopping the 
convulsion by IV injection upon arrival at the healthcare setting. In the community setting, a
therapeutic agent that can be administered by a nonmedical expert, such as a parent or caregiver, 
would be more appropriate for emergency treatment. 
For pediatric patients in Japan, midazolam has been used off-label as a first or second choice 
medication for seizures intractable to diazepam treatment. Since the approval of MIDAFRESA
Injection 0.1% in 2014, midazolam IV injection is now positioned as first-choice medication in 
Japan for pediatric patients with SE; however, the IV formulation is too dilute to use for 
oromucosal delivery. DORMICUM (an injectable IV formulation of midazolam) is frequently 
administered oromucosally or intranasally, which is considered to be an off-label use of this 
drug.
Accordingly, it has been recognized that there is an unmet need for an effective, fast-acting 
treatment that can easily be administered by a more convenient route and by individuals other 
than medical experts and that is suitable for use in both the healthcare setting and community
(Scott et al., 1999).

1.3
Unmet Medical Need for Buccal Midazolam
To fulfill such unmet needs as outlined above, it has been common practice to administer 
midazolam buccally (oromucosal administration of other midazolam formulations) off-label for 
the treatment of SE. Buccal administration does not cause pain or distress to the patient or 
require that the patient be in the prone position. 
Currently, the national average time in Japan for patients with SE to be transported to the 
healthcare setting is 39.6 minutes. In many cases as much as 50 minutes has been reported until 
medical treatment has been received at the healthcare setting. Buccal midazolam treatment in 
children with seizures could be started at home by trained clinical personnel, family members, or 
caregivers before securing vascular access, as well as after arriving at a medical institution, thus 
potentially reducing life-threatening risks of brain disorders (eg, encephalopathy) and other 
sequelae due to prolonged seizures and resulting from delays in getting the child to a healthcare
setting.
1.4
Product Background and Clinical Information
The investigational product midazolam hydrochloride oromucosal solution (hereafter referred to 
as MHOS/SHP615) contains 5 mg/mL of the active substance midazolam and has been 
specifically developed for the buccal administration of midazolam in children with SE. 
Currently, there is extensive clinical experience with midazolam as it is authorized for use in 
children (including neonates <32 weeks’ gestational age in intensive care units) and adults as a 
sedative and in anesthesia and may be given by the IV, intramuscular (IM), or rectal route of 
administration. As midazolam undergoes significant first pass metabolism in both the small 
intestine and the liver, a systemic drug delivery system was selected for MHOS/SHP615. In 
suspension, midazolam is water soluble and, therefore, readily absorbed via the buccal mucosa. 
At physiological pH the drug becomes lipid soluble, which enables it to cross the blood-brain 
barrier. In addition, its PK parameters such as the short elimination half-life (1.5-2.5 hours) and 
rapid plasma clearance (300-500 mL/min) are optimal for a rescue medication 
(Hypnovel SmPC, 2008). The buccal mucosa, with its expanse of smooth muscle and relative 
immobility, makes it a desirable region for retentive systems used for oral transmucosal drug 
delivery.
MHOS/SHP615 has a formulation essentially identical to its authorized originator product, a 
systemically administered midazolam hydrochloride (HYPNOVEL® Injection 10 mg/2 mL [EU], 
VERSED® Oral Syrup 2 mg/mL now marketed generically [US], and DORMICUM Injection 10 mg 
[Japan]) used for sedation or anesthetic premedication. When approved in Japan,
MHOS/SHP615, will provide major advantages over unauthorized/off-label buccal midazolam 
preparations and other formulations of authorized rescue medication (such as IV, IM, or rectal
routes of administration) currently used for SE.
In the EU, MHOS is commercially known as BUCCOLAM®, a non-IV treatment to stop seizures 
(including convulsive seizures). An oromucosal solution, BUCCOLAM contains 5 mg/mL of the 
active substance midazolam and was approved in the EU on 05 Sep 2011 for the treatment of

prolonged, acute, convulsive seizures in infants, toddlers, children, and adolescents (from 
3 months to ≤18 years).
Parents and/or caregivers are allowed to administer BUCCOLAM only to patients older than 
6 months who have been diagnosed with epilepsy. For infants between 3 and 6 months of age, 
treatment should be in a healthcare setting, where close medical supervision and resuscitation 
equipment are available.
Efficacy
The age range proposed for the SHP615-301 study is ≥52 weeks corrected gestational age 
(gestational weeks plus the number of weeks after birth) and <18 years. The efficacy and safety 
of buccal midazolam have been established in 4 pivotal, rectal-diazepam-controlled clinical 
studies. These studies all used the HYPNOVEL 10 mg/2 mL formulation delivered buccally. All 
4 studies demonstrated that buccal midazolam was either more effective than or as effective as 
rectal diazepam for the treatment of acute seizures in children (licensed indication and dosage of 
diazepam). However, the meta-analysis of the 3 (standard randomized) pivotal studies 
(Mpimbaza et al., 2008; McIntyre et al., 2005; Scott et al., 1999; Baysun et al., 2005)
(comprising a total of 628 seizure events [525 patients]) demonstrated that buccal midazolam is 
significantly more effective than rectal diazepam in stopping seizures within 10 minutes 
(Mantel-Haenszel Weighted Risk Ratio [buccal midazolam/rectal diazepam] of 1.24 [95% 
confidence interval {CI}: 1.11 - 1.39] P = 0.0002).
In a study vs IV diazepam (Talukdar and Chakrabarty, 2009), the buccal midazolam dose 
was slightly lower than that used in the pivotal rectal diazepam studies (0.2 mg/kg vs 
~0.25-0.5 mg/kg in the pivotal studies). Nevertheless, this study supported the results of the 
pivotal studies and meta-analysis. It demonstrated that buccal midazolam is an effective 
treatment for acute seizures with no statistically significant difference compared with IV 
diazepam for overall control of convulsive episodes within 5 minutes (85% vs 93.3% in buccal 
midazolam vs IV diazepam groups, respectively; p = 0.142). 
Safety
The clinical safety profile of midazolam (and other benzodiazepines) from the authorized uses is 
well established (and summarized in the EU and US labeling [Hypnovel SmPC, 2008;
Midazolam HCl Injection US Prescribing Information, 2009; Midazolam HCl Syrup US 
Prescribing Information, 2009]). The main adverse effects (reported to occur rarely for 
HYPNOVEL) and precautions applicable to the buccal route of administration in children include 
cardiorespiratory adverse events (AEs) (respiratory depression, apnea, respiratory arrest, and/or 
cardiac arrest), anterograde amnesia, and paradoxical reactions. Precautions are required for 
patients with impaired respiratory function or cardiovascular instability. Pediatric patients 
<6 months of age are particularly vulnerable to airway obstruction and hypoventilation.
Pharmacokinetics
Published PK studies in healthy adult volunteers have shown that buccal midazolam is quickly 
absorbed (producing peak concentrations at 30 minutes with a mean buccal midazolam 
bioavailability of 74.5% [Schwagmeier et al., 1998]) and has a rapid effect (≤5-10 minutes) on 
the central nervous system (CNS), shown on electroencephalography (Scott et al., 1998). The
rapid absorption of midazolam by the buccal route has also been demonstrated in a published

study in children with severe malaria and convulsions (peak concentration at 10 [5–40] minutes 
with bioavailability estimated at 87%) (Muchohi et al., 2008).
For this open label SHP615-301 study, the MHOS/SHP615 formulation (the same as the 
HYPNOVEL 10 mg/2 mL formulation) and the proposed fixed doses will be the same as the 
4 pivotal, rectal-diazepam-controlled clinical studies. Thus, the PK/pharmacokinetics should not 
be different for MHOS compared to that in the pivotal efficacy/safety studies.
Always refer to the latest version of the SHP615 Midazolam HCl investigator’s brochure for the 
overall risk/benefit assessment and the most accurate and current information regarding the drug 
metabolism, pharmacokinetics, efficacy and safety of MHOS/SHP615.

STUDY OBJECTIVES AND PURPOSE
2.1
Rationale for the Open-Label Study (SHP615-301)
For treatment of acute seizures in children, rectal diazepam is the medication most commonly 
used when IV access is not possible either in the medical or community settings. The rectal route 
of administration, however, is not always practical, socially acceptable, or convenient. 
The need to remove clothing and the difficulty with rectal administration during seizures, 
particularly for wheelchairs users, is socially embarrassing or unacceptable by some individuals, 
parents, or caregivers.
MHOS/SHP615 has been specifically developed as a single, age-specific, fixed dose 
(approximately 0.25 to 0.5 mg/kg as midazolam) presentation for children. The 4 different,
age-specific, fixed-dose presentations were selected as a convenient oromucosal administration 
of midazolam injectable solution to enable rapid treatment in the emergency and community 
settings where individual dosing by body weight is not feasible (except for infants aged from 
3 months to <6 months: this age population should be treated in a healthcare setting only). This 
dosing regimen was evaluated extensively by the European Medicines Agency (EMA) Paediatric
Committee as part of the PIP application and by the EMA Committee for Medicinal Products for 
Human Use (CHMP) as part of the review and approval of the Paediatric-use marketing
authorisation (PUMA).
The rationale for this interventional open-label study is to determine the efficacy, safety, and 
pharmacokinetics of MHOS/SHP615 in pediatric patients with CSE.

STUDY DESIGN
3.1
Study Design 
SHP615-301 is a Phase 3, multicenter, interventional, nonrandomized, open-label study of 
buccally administered MHOS/SHP615 to pediatric subjects who present with SE in the 
healthcare setting. 
Approximately 25 subjects will be enrolled in this study. Children whose corrected gestational 
age is ≥52 weeks (gestational weeks plus the number of weeks after birth) and <18 years (and 
weight >5 kg) who arrive at the healthcare setting in full seizure, have not received immediate 
treatment, and have parent, guardian, or legally authorized representative informed 
consent/assent (when applicable, per Shire policy and country regulations), are eligible to 
participate providing all eligibility criteria are met. The seizure event(s) must be accompanied by 
loss of consciousness and can be either generalized tonic clonic or start focally and then 
generalize.
This study consists of a 24-hour, open-label treatment period followed by a 1-week safety 
follow-up period. Upon entry in the SHP615-301 study, subjects will receive a single open-label 
MHOS/SHP615 treatment, dosing stratified by age (2.5, 5, 7.5, or 10 mg buccally).
The efficacy of MHOS/SHP615 in stopping convulsive seizures will be assessed by measuring 
the percentage of subjects whose initial seizure stops within 10 minutes with a sustained absence 
of visible seizure activity for 30 minutes following a single, age-based dose of MHOS/SHP615. 
If the seizures have not stopped within 10 minutes after a single dose of MHOS/SHP615, the 
subject will be treated according to the participating healthcare setting protocol or guideline. The 
safety and pharmacokinetics of MHOS/SHP615 will also be assessed.
Subjects will be monitored by assessment of TEAEs, vital signs, laboratory tests, oxygen 
saturation, physical examination, and ECGs for safety evaluations. All subjects treated in this 
study will be followed for 1 week after dosing for safety evaluations.
3.2
Duration and Study Completion Definition
The duration of the treatment visit will be at least 6 hours and up to 24 hours, with a follow-up 
visit 1 week after the administration of MHOS/SHP615. It is anticipated that subjects will arrive 
at the healthcare setting while experiencing a seizure. Subjects will be screened and assessed at 
baseline immediately before administration of investigational product even if the informed 
consent and some prescreening assessments were completed at a previous clinical visit. 

Shire

Midazolam
28 Aug 2017
Evaluation of seizure symptoms will be conducted up through 6 hours after the administration of 
the investigational product. After 6 hours, the subject may be discharged from the healthcare 
setting study site. 
The subject’s maximum duration of participation is expected to be approximately 1 week. The 
study will be completed in approximately 2 years. 
The Study Completion Date is defined as the date the final subject, across all sites, completes the 
protocol-defined assessments, or discontinues the study. Please note that this includes the 
follow-up visit or contact, whichever is later. The Study Completion Date is used to ascertain 
timing for study results posting and reporting.
3.3
Sites and Regions
This study will be conducted in approximately 25 healthcare setting study sites in Japan.

STUDY POPULATION
Each subject (parent, guardian, or legally authorized representative) must participate in the 
informed consent process and provide written informed consent/assent (when applicable, per 
Shire policy and country regulations) before any procedures specified in the protocol are 
performed. The subject may be prescreened by the investigator in their clinical practice and the 
parent, guardian, or legally authorized representative may sign informed consent before the 
subject presents to the healthcare setting for treatment of the seizure.
The total enrollment for the SHP615-301 study is expected to be approximately 25 subjects
(minimum 3 subjects per age group) with active generalized tonic-clonic SE with seizures.
Diagnosis of SE will be confirmed through documented medical history and evaluation of 
seizure symptoms conducted either during the screening/baseline assessment period or during
treatment.

entered on the CRF. 
Reasons for discontinuation include but are not limited to:

AE

Protocol deviation

Withdrawal by subject, parent, guardian, or legally authorized representative

Lost to follow-up

The sponsor or investigator terminates the study
Withdrawal/discontinuation due to AEs should be distinguished from withdrawal due to other 
causes, according to the definition of AE noted earlier, and recorded on the appropriate AE CRF 
page. When a subject withdraws because of an SAE, the SAE must be reported in accordance 
with the reporting requirements defined in Section 8.2.
Sponsor Discontinuation Criteria
Premature termination of this study may occur because of a regulatory authority decision, change 
in opinion of the reviewing institutional review board (IRB), or investigational product safety 
problems, or at the discretion of the sponsor. In addition, the sponsor retains the right to 
discontinue development of SHP615 at any time.
If a study is prematurely terminated or discontinued, the sponsor will promptly notify the 
investigator. After notification, the investigator must contact all subjects and subject’s parents, 
guardians, or legally authorized representatives and the healthcare setting pharmacy (if 
applicable) within 28 days. As directed by the sponsor, all study materials must be collected and 
all CRFs completed to the greatest extent possible.
4.5.2
Subjects “Lost to Follow-up” Prior to Last Scheduled Visit
A minimum of 3 documented attempts must be made to contact the parent, guardian, or legally 
authorized representative of any subject lost to follow-up at any time point prior to the last 
scheduled contact (office visit or telephone contact). At least 1 of these documented attempts 
must include a written communication sent to the parents, guardians, or legally authorized 
representatives at subject’s last known address via courier or mail (with an acknowledgement of 
receipt request) asking that they return to the site for final safety evaluations.

INVESTIGATIONAL PRODUCT
6.1
Identity of Investigational Product
MHOS/SHP615 is a clear, colorless, ready-to-use solution (containing 5 mg midazolam [as 
hydrochloride] per mL). MHOS/SHP615 has been specifically developed as a single, 
age-specific, fixed dose (approximately 0.25 to 0.5 mg/kg as midazolam) formulation for buccal 
administration in children, 1 dosage per each of the following age groups:

2.5 mg (yellow label) ages 3 months (52 weeks corrected gestational age) to <1 year (and 
weight >5 kg)

5 mg (blue label) ages 1 year to <5 years

7.5 mg (purple label) ages 5 years to <10 years

10 mg (orange label) ages 10 years to <18 years
The investigational product MHOS/SHP615 will be provided in prefilled single-use,
ready-to-use, amber, age-specific, and color-coded oral dosing syringes, and is to be 
administered by the buccal (oromucosal) route. The full amount of solution will be delivered
slowly into the space between the inside of the cheek and the lower gum. 
Buccal (oromucosal) administration was considered to be an appropriate route to be progressed 
to address the unmet need for a convenient, fast–acting product suitable for use in both the

Blinding the Treatment Assignment
Not applicable.
6.2
Administration of Investigational Product(s)
6.2.1
Allocation of Subjects to Treatment 
This is an open-label, nonrandomized study; therefore, assignment to MHOS/SHP615 will be 
unblinded to the investigators, subjects, and the sponsor study team. Study treatment will only be 
administered by the healthcare setting study investigator or subinvestigator to subjects who have 
a signed and dated IRB-approved ICF and who have met all eligibility criteria. 
All subjects enrolled in the study will receive treatment with the investigational product based on 
their age (Section 6.2.2.1).
Subject numbers are assigned to all subjects as they present for enrollment. Within each site 
(numbered uniquely within a protocol), the subject number is assigned to subjects according to 
the sequence of presentation for study participation. This identifying number will be retained 
throughout the study.
Once a unique identifier has been assigned, that number must not be used again if, for example, a 
subject is withdrawn from the study. If an identifier is allocated incorrectly, the clinical research 
associate (CRA)/study monitor must be notified as soon as the error is discovered. 
6.2.2
Dose Regimen and Dose Administration
MHOS/SHP615 will be administered buccally by the investigator or subinvestigator as a single, 
fixed dose product, banded by age to subjects with CSE in the healthcare setting. For buccal 
administration, MHOS/SHP615 is administered into the space between the lower gum and the 
inside of the cheek.
6.2.2.1
Dosing Regimen 
Details of subject dosing and follow-up are outlined in Section 3.1 and included in the Schedule 
of Assessments (Table 1).
There are 4 single, fixed, banded by age, dose regimens of the MHOS/SHP615 formulation for 
the treatment of SE; 1 dosage per buccal administration for each of the following age groups:
2.5 mg
3 months (52 weeks corrected gestational age) to <1 year (and weight >5 kg)
5 mg
1 to <5 years
7.5 mg
5 to <10 years
10 mg
10 to <18 years

6.2.2.2
Dose Administration
Only 1 syringe with the specified dose must be given. The full amount of the MHOS pre-filled 
dosing syringe is injected slowly into the buccal mucosa. In some cases, it might be necessary to 
divide the dose so that half of the solution is injected into each side of mouth.
All investigational product is dispensed by the investigator or subinvestigator.
Prior to administration of drug therapy, the airway should be secured and respiratory and cardiac 
function assessed (NICE Guidance National Institute for Health and Care Excellence, 2011). 
6.3
Labeling, Packaging, Storage, and Handling
6.3.1
Labeling
Labels containing study information and pack identification are applied to the investigational 
product(s) container. 
A computer-generated label is applied to the investigational product. All investigational product 
is labeled with a minimum of the protocol number, pack number (if applicable), dosage form 
(including product name and quantity in pack), directions for use, storage conditions, expiry date 
(if applicable), batch number and/or packaging reference, the statements “For clinical trial use 
only” and the name and country of the sponsor and Quintiles name and address. 
Any additional labeling requirements for participating countries and/or controlled substances will 
also be included on the label.
Additional labels (eg, those used when dispensing marketed product) may, on a case-by-case 
basis, be applied to the investigational product in order to satisfy local or institutional 
requirements, but must not:

Contradict the clinical study label.

Obscure the clinical study label.

Identify the study subject by name.
Additional labels may not be added without the sponsor’s prior full agreement.
6.3.2
Packaging
The investigational product MHOS/SHP615 will be provided in individual, labeled, single-dose, 
prefilled plastic, oral dosing syringes available in 4 different, age-specific, color-coded doses 
(2.5, 5, 7.5, and 10 mg dose packs) in a protective plastic tube which are packaged and dispensed 
in cartons with tamper-evident seals. The cartons should not be opened until the investigational 
product is to be administered.
Changes to sponsor-supplied packaging prior to dosing may not occur without full agreement in 
advance by the sponsor.

6.3.3
Storage
The investigator has overall responsibility for ensuring that investigational product is stored in a 
secure, limited-access location. Limited responsibility may be delegated to the pharmacy or 
member of the study team, but this delegation must be documented. 
Keep the oral dosing syringe containing the investigational product in the protective plastic tube. 
Keep at or below 25°C (77°F). Do not refrigerate or freeze.
Investigational products are distributed by the pharmacy or nominated member of the study 
team. The subinvestigator/designated team member will enter the unique subject identifier on the 
investigational product bottle/carton labels as they are distributed.
Investigational product must be stored in accordance with labeled storage conditions. 
Temperature monitoring is required at the storage location to ensure that the investigational 
product is maintained within an established temperature range. The investigator is responsible 
for ensuring that the temperature is monitored throughout the duration of the study and that 
records are maintained; the temperature should be monitored continuously by using either an 
in-house system, a mechanical recording device such as a calibrated chart recorder, or by manual 
means, such that both minimum and maximum thermometric values over a specific time period 
can be recorded and retrieved as required. Such a device (ie, certified min/max thermometer) 
would require manual resetting upon each recording. 
The sponsor must be notified immediately upon discovery of any excursion from the established 
range. Temperature excursions will require site investigation as to cause and remediation. The 
sponsor will determine the ultimate impact of excursions on the investigational product and will 
provide supportive documentation as necessary. Under no circumstances should the product be 
dispensed to subjects until the impact has been determined and the product is deemed appropriate 
for use by the sponsor.
The sponsor should be notified immediately if there are any changes to the storage area of the 
investigational product that could affect the integrity of the product(s), eg, fumigation of a 
storage room.
6.3.4
Special Handling
Investigational product for the sponsor’s studies must be stored according to all applicable local, 
state, and/or national laws. 
6.4
Drug Accountability
Investigators will be provided with sufficient amounts of the investigational product to carry out 
this protocol for the agreed number of subjects. The investigator or designee will acknowledge 
receipt of the investigational product, documenting shipment content and condition. Accurate 
records of all investigational product dispensed, used, returned, and/or destroyed must be 
maintained as detailed further in this section.
The investigator has overall responsibility for administering/dispensing investigational product. 
Where permissible, tasks may be delegated to a subinvestigator who is adequately trained in the

protocol and who works under the direct supervision of the investigator. This delegation must be 
documented in the applicable study delegation of authority form.
The investigator or his/her designee (as documented by the investigator in the applicable study 
delegation of authority form) will administer the investigational product only to subjects 
included in this study following the procedures set out in the study protocol. Each subject will be 
given only the investigational product carrying his/her treatment assignment. All administered 
investigational product will be documented on the CRFs and/or other investigational product 
record. 
No investigational product stock or returned inventory from a Shire-sponsored study may be 
removed from the site where originally shipped without prior knowledge and consent by the 
sponsor. If such transfer is authorized by the sponsor, all applicable local, state, and national 
laws must be adhered to for the transfer.
At the end of the study, or as instructed by the sponsor, all unused stock and empty/used 
investigational product packaging are to be sent to a nominated contractor on behalf of the 
sponsor. Investigational product being returned to the sponsor’s designated contractors must be 
counted and verified by clinical site personnel and the sponsor (or designated CRO). For unused 
supplies where the original supplied tamper-evident feature is verified as intact, the 
tamper-evident feature must not be broken and the labeled amount is to be documented in lieu of 
counting. Shipment return forms, when used, must be signed prior to shipment from the site. 
Returned investigational product must be packed in a tamper-evident manner to ensure product 
integrity. Contact the sponsor for authorization to return any investigational product prior to 
shipment. Shipment of all returned investigational product must comply with local, state, and 
national laws.
The investigative site must maintain adequate records documenting the receipt, use, loss, or other 
disposition of the investigational product supplies.
6.5
Subject Compliance
All doses of open-label MHOS/SHP615 administered at the investigational site will be by the 
investigator or subinvestigator.
Drug accountability must be assessed at the container/packaging level for unused investigational 
product that is contained within the original tamper-evident sealed container (eg, bottles, trays, 
vials) or at the individual count level for opened containers/packaging. The pharmacist or 
investigator-identified designee will record details on the drug accountability form.
6.6
Destruction of Investigational Product
The sponsor or designee will provide guidance on the destruction of unused investigational 
product (eg, at the site). If destruction is authorized to take place at the study site, the investigator 
must ensure that the materials are destroyed in compliance with applicable environmental 
regulations, institutional policy, and any special instructions provided by the sponsor, and all 
destruction must be adequately documented.

Shire
CONFIDENTIAL
Page 37
SHP615-301 Protocol Amendment 2
Midazolam
28 Aug 2017
At the end of this period there will be a follow up visit to evaluate seizure symptoms, review 
concomitant medications, conduct a physical examination, and query for serious adverse events 
(SAEs), AEs. All AEs and SAEs that are not resolved at the time of this contact will be followed 
to closure (see Section 8).
7.1.6
Additional Care of Subjects after the Study
No aftercare is planned for this study. It is the responsibility of the investigator to counsel 
subjects on their treatment alternatives when they exit the study.
7.2
Study Evaluations and Procedures
Every effort should be made to ensure that the protocol-required tests and procedures are 
completed as described. However, it is anticipated that from time to time there may be 
circumstances outside of the control of the investigator that may make it unfeasible to perform
the test. In these cases the investigator will take all steps necessary to ensure the safety and 
well-being of the subject. When a protocol-required test cannot be performed, the investigator 
will document the reason for this and any corrective and preventive actions that he or she has 
taken to ensure that normal processes are adhered to as soon as possible. The study team will be 
informed of these incidents in a timely fashion.
7.2.1
Informed Consent
The informed consent form (ICF) must be executed prior to performing any study-related 
activities and the ICF must be approved by the reviewing IRB. The subject or the subject’s 
parents, guardians, or legally authorized representatives may withdraw consent at any time. The 
subject may be prescreened by the investigator in their clinical practice and the parent, guardian, 
or legally authorized representative may sign informed consent before the subject presents to the 
healthcare setting for treatment of the seizure. If more than 3 months have elapsed between 
initial informed consent and seizure, the parent, guardian, or legally authorized representative 
should re-sign at the time of admission prior to treatment. Participation in the study may be 
terminated at any time without the consent of subjects or subject’s parents, guardians, or legally 
authorized representatives as determined by the investigator.
7.2.2
Demographic and Other Baseline Characteristics
Demographics: date of birth, sex, race and ethnicity (where locally permitted) and medical 
history will be obtained at Screening from parents or caregivers and will be recorded on the 
source document and CRF.
Medical history (including SE) will capture the subject’s current medical status (current SE or 
CSE disease process), past medical status (past disease processes), history of surgery, allergies, 
and concomitant medications/treatments.
7.2.3
Efficacy
Evaluation of seizure activity will be conducted throughout the study to assess the therapeutic 
success.

7.2.4
Safety
The name and address of each third-party vendor (eg, clinical laboratory) used in this study will 
be maintained in the investigator’s and sponsor’s files.
7.2.4.1
Medical and Medication History
The investigator will perform a complete medical history at Screening, including a medication 
history, and record all information gathered. The investigator must record all clinically or 
medically relevant information regardless of how much time has elapsed since the date of 
diagnosis.
With the consent of parents, guardians, or legally authorized representatives of participating 
subjects, medical records from other treatment providers should be requested. 
Refer to Section 5.1 for full details on collection of prior treatment. Prior treatment information, 
including any prior treatments for SE (eg, dietary, medication, or other), must be recorded on the 
appropriate CRF page.
7.2.4.2
Physical Examination 
A complete physical examination will be performed at some time point between dosing 
(0 minute) and 6 hours post-dose, and at the follow-up. Height (without shoes) and weight will 
be measured during the first exam.
Complete physical examinations must be performed by the investigator or subinvestigator in 
accordance with standards at the site and per local guidelines. Complete physical examinations 
consist of assessments of:

General appearance 


Abnormalities identified at Screening will be documented in the subject’s source documents and 
on the medical history CRF. Changes after the Screening visit will be captured as AEs on the AE 
CRF page, as deemed by the investigator.
7.2.4.3
Adverse Event Collection
At each study time point, subjects (or parent, guardian, or legally authorized representative) will 
be questioned in a general way to ascertain if AEs have occurred since the previous time point. 
Adverse events are collected from the time informed consent is signed when the subject with SE
arrives at the hospital or healthcare setting, or if the informed consent has been previously 
signed, from the time the subject begins evaluation and treatment in the hospital or healthcare 
setting for SE, to completion of the follow-up visit. (Please refer to Section 8, Adverse and 
Serious Adverse Events Assessment.)
7.2.4.4
Vital Signs
Vital signs will be conducted after the subject has been supine for at least 5 minutes immediately 
prior to the assessment include blood pressure (systolic and diastolic), pulse rate, respiration rate
(after 5 minutes of rest), and body temperature to be performed at the time points specified in the 
Schedule of Assessments (Table 1). Additional collection times or changes to collection times 
will be permitted, as necessary to ensure appropriate collection of safety data.
Supine blood pressure will be measured with the subject’s arm supported at the level of the heart, 
and recorded to the nearest mm Hg. It is preferred that the same arm (preferably the dominant 
arm) will be used throughout the study. The same size BP cuff that has been properly sized and 
calibrated will be used to measure BP each time.
The use of automated devices for measuring BP and pulse rate are acceptable, although, when 
done manually, pulse rate will be measured in the brachial/radial artery for at least 30 seconds. 
When the timing of these measurements coincides with a blood collection, all vital signs should 
be obtained prior to the nominal time of the blood collection.
It is preferred that body temperature be collected using tympanic, oral, or axillary methods and 
that the same method be used consistently throughout the study.
Any clinically significant deviations from the initial vital signs that are deemed clinically 
significant in the opinion of the investigator are to be recorded as an AE.
7.2.4.5
Clinical Laboratory Evaluations
Clinical laboratory assessments will be performed at Screening, at 4 hours postdose, and at 
24 hours postdose if the subject is still at the healthcare setting. The following clinical laboratory 
assessments will be performed:

draw for each subject will be approximately 14.25 mL.
All clinical laboratory assays will be performed according to the laboratory’s normal procedures. 
Reference ranges are to be supplied by Quintile’s central laboratory and will be used to assess 
the clinical laboratory data for clinical significance and out-of-range pathological changes. The 
investigator should assess out-of-range clinical laboratory values for clinical significance, 
indicating if the value(s) is/are not clinically significant or clinically significant. Abnormal 
clinical laboratory values, which are unexpected or not explained by the subject’s clinical 
condition, may, at the discretion of the investigator or sponsor, be repeated as soon as possible 
until confirmed, explained, or resolved.
Blood samples for laboratory assessments will be collected at the site by a trained phlebotomist 
designated and/or approved by the study investigator. Details for the collection, processing, 
storage and shipment of samples for all laboratory determinations will be provided in the 
Laboratory Manual. 
Blood, serum, and urine samples will be stored and secured in a manner that assures that 
unauthorized access is prohibited and the samples are not lost, allowed to deteriorate, or 
accidentally or illegally destroyed.

Electrocardiogram 
A standard twelve (12)-lead electrocardiogram (ECG, single recording) will be performed at 
time points specified in the Schedule of Assessments (Table 1).
When the timing of these measurements coincides with a blood collection, the ECG should be 
obtained prior to the nominal time of the blood collection, BP, and pulse rate.
The investigator or subinvestigator at the investigator site will make comparisons to baseline 
measurements taken at screening, if available. A copy of the ECG should be available as source 
documents for review.

Oxygen saturation
Oxygen saturation will be measured at time points specified in the Schedule of Assessments 
(Table 1). Oxygen saturation at baseline will be measured and recorded on room air, if feasible, 
in the emergency room.
If it is not possible for the subject to have an oxygen saturation obtained on room air due to 
medical concerns, this will be recorded and the investigator will record the oxygen saturation of 
the patient while on oxygen therapy as well as the oxygen delivery system and amount of oxygen 
administered (eg, 2 L/min via nasal cannula).

Pharmacokinetic Assessments
Blood samples (~1.25 mL) to provide a minimum of 0.5 mL plasma for the assessment of plasma 
midazolam and 1-hydroxymidazolam concentrations will be collected (from all subjects who 
received investigational product) and analyzed at the specified time points for the duration of the 
study at the time points specified in the Schedule of Assessments (Table 1). The exact time of the 
sample collection should be noted on the source document and data collection tool (eg, CRF).
Samples will be analyzed for midazolam and 1-hydroxymidazolam using a validated assay. The 
methodologies will be appropriately validated in compliance with the CRO’s standard operating 
procedures. 
The address for shipment of serum samples and contact information for the laboratory analysis of 
midazolam and 1-hydroxymidazolam will be provided to the investigator site prior to initiation 
of the trial.

ADVERSE AND SERIOUS ADVERSE EVENTS ASSESSMENT
8.1
Definition of Adverse Events, Period of Observation, Recording of Adverse Events
An AE is any untoward medical occurrence in a clinical investigation subject administered a 
pharmaceutical product and that does not necessarily have a causal relationship with this 
treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
(investigational) product, whether or not related to the medicinal (investigational) product (ICH 
Guidance E2A 1995). 
All AEs are collected from the time the informed consent is signed when the subject with SE
arrives at the hospital or healthcare setting or if the informed consent has been previously signed, 
from the time the subject begins evaluation and treatment in the hospital or healthcare setting for 
SE, until the defined follow-up period stated in Section 7.1.5. This includes events occurring 
during the screening phase of the study, regardless of whether or not investigational product is 
administered. Where possible, a diagnosis rather than a list of symptoms should be recorded. If a 
diagnosis has not been made, then each symptom should be listed individually. All AEs should 
be captured on the appropriate AE pages in the CRF and in source documents. In addition to 
untoward AEs, unexpected benefits outside the investigational product indication should also be 
captured on the AE CRF.
All AEs must be followed to closure (the subject’s health has returned to his/her baseline status 
or all variables have returned to normal), regardless of whether the subject is still participating in 

Shire
CONFIDENTIAL
Page 43
SHP615-301 Protocol Amendment 2

the study. Closure indicates that an outcome is reached, stabilization achieved (the investigator 
does not expect any further improvement or worsening of the event), or the event is otherwise 
explained. When appropriate, medical tests and examinations are performed so that resolution of 
event(s) can be documented.
8.1.1
Severity Categorization
The severity of AEs must be recorded during the course of the event including the start and stop 
dates for change in severity. An event that changes in severity should be captured as a new event. 
Worsening of pre-treatment events, after initiation of investigational product, must be recorded 
as new AEs (for example, if a subject experiences mild intermittent dyspepsia prior to dosing of 
investigational product, but the dyspepsia becomes severe and more frequent after investigational 
product has been administered, a new AE of severe dyspepsia [with the appropriate date of 
onset] is recorded on the appropriate CRF).
The medical assessment of severity is determined by using the following definitions:
Mild:
A type of AE that is usually transient and may require only minimal treatment or 
therapeutic intervention. The event does not generally interfere with usual 
activities of daily living.
Moderate:
A type of AE that is usually alleviated with specific therapeutic intervention. The 
event interferes with usual activities of daily living, causing discomfort but poses 
no significant or permanent risk of harm to the research subject.
Severe:
A type of AE that interrupts usual activities of daily living, or significantly affects 
clinical status, or may require intensive therapeutic intervention.
8.1.2
Relationship Categorization
A physician/investigator must make the assessment of relationship to investigational product for 
each AE. The investigator should decide whether, in his/her medical judgment, there is a 
reasonable possibility that the event may have been caused by the investigational product. If 
there is no valid reason for suggesting a relationship, then the AE should be classified as “not 
related.” Otherwise, if there is any valid reason, even if undetermined or untested, for suspecting 
a possible cause-and-effect relationship between the investigational product and the occurrence 
of the AE, then the AE should be considered “related.” The causality assessment must be 
documented in the source document.

The following additional guidance may be helpful:
Term
Relationship Definition
Related
The temporal relationship between the event and the administration of the 
investigational product is compelling and/or follows a known or suspected response 
pattern to that product, and the event cannot be explained by the subject’s medical 
condition, other therapies, or accident.
Not Related
The event can be readily explained by other factors such as the subject’s underlying 
medical condition, concomitant therapy, or accident and no plausible temporal or 
biologic relationship exists between the investigational product and the event.
8.1.3
Outcome Categorization
The outcome of AEs must be recorded during the course of the study on the CRF. Outcomes are 
as follows:

Fatal

Not Recovered/Not Resolved

Recovered/Resolved

Recovered/Resolved With Sequelae 

Recovering/Resolving

Unknown
8.1.4
Symptoms of the Disease Under Study
Symptoms of the disease under study should not be classed as AEs as long as they are within the 
normal day-to-day fluctuation or expected progression of the disease and are part of the efficacy 
data to be collected in the study; however, significant worsening of the symptoms should be 
recorded as an AE.
8.1.5
Clinical Laboratory and Other Safety Evaluations
A change in the value of a clinical laboratory, vital sign, or ECG assessment can represent an AE 
if the change is clinically relevant or if, during treatment with the investigational product, a shift 
of a parameter is observed from a normal value to an abnormal value, or a further worsening of 
an already abnormal value. When evaluating such changes, the extent of deviation from the 
reference range, the duration until return to the reference range, either while continuing treatment 
or after the end of treatment with the investigational product, and the range of variation of the 
respective parameter within its reference range, must be taken into consideration.
If, at the end of the treatment phase, there are abnormal clinical laboratory, vital sign, or ECG 
values which were not present at the pretreatment value observed closest to the start of study 
treatment, further investigations should be performed until the values return to within the 
reference range or until a plausible explanation (eg, concomitant disease) is found for the 
abnormal values.

Shire
CONFIDENTIAL

The investigator should decide, based on the above criteria and the clinical condition of a 
subject, whether a change in a clinical laboratory, vital sign, or ECG parameter is clinically 
significant and therefore represents an AE.
8.1.6
Pregnancy
All pregnancies are to be reported from the time informed consent is signed until the defined 
follow-up period stated in Section 7.1.5.
Any report of pregnancy for any female study participant must be reported within 24 hours to 
Quintiles Transnational Japan K.K. and the Shire Global Pharmacovigilance and Risk 
Management Department using the Shire Investigational and Marketed Products Pregnancy 
Report Form. A copy of the Shire Investigational and Marketed Products Pregnancy Report 
Form (and any applicable follow-up reports) must also be sent to the CRO/Shire medical monitor 
using the details specified in the emergency contact information section of the protocol. The 
pregnant female study participant must be withdrawn from the study.
Every effort should be made to gather information regarding the pregnancy outcome and 
condition of the infant. It is the responsibility of the investigator to obtain this information within 
30 calendar days after the initial notification and approximately 30 calendar days postpartum. 
Pregnancy complications such as spontaneous abortion/miscarriage or congenital abnormality 
are considered SAEs and must be reported using the Shire Clinical Study Serious Adverse Event 
and Non-serious AEs Required by the Protocol Form. Note: An elective abortion is not 
considered an SAE.
In addition to the above, if the investigator determines that the pregnancy meets serious criteria,
it must be reported as an SAE using the Shire Clinical Study Serious Adverse Event and 
Non-serious AEs Required by the Protocol Form as well as the Shire Investigational and 
Marketed Products Pregnancy Report Form. The test date of the first positive serum/urine -hCG 
test or ultrasound result will determine the pregnancy onset date.
8.1.7
Abuse, Misuse, Overdose, and Medication Error
Abuse, misuse, overdose, or medication error (as defined below) must be reported to the sponsor 
according to the SAE reporting procedure whether or not they result in an AE/SAE as described 
in Section 8.2. Note: The 24-hour reporting requirement for SAEs does not apply to reports of 
abuse, misuse, overdose, or medication errors unless these result in an SAE. 
The categories below are not mutually exclusive; the event can meet more than 1 category.

Abuse – Persistent or sporadic intentional intake of investigational product when used for a 
non-medical purpose (eg, to alter one’s state of consciousness or get high) in a manner that 
may be detrimental to the individual and/or society

Misuse – Intentional use of investigational product other than as directed or indicated at any 
dose (Note: this includes a situation where the investigational product is not used as directed 
at the dose prescribed by the protocol)

Shire
CONFIDENTIAL


Overdose – Intentional or unintentional intake of a dose of an investigational product 
exceeding a pre-specified total daily dose of the product. 

Medication Error – An error made in prescribing, dispensing, administration, and/or use of 
an investigational product. For studies, medication errors are reportable to the sponsor only 
as defined below.
The administration and/or use of an expired investigational product should be considered as a 
reportable medication error.

Reference Safety Information
The reference for safety information for this study is the SHP615 Midazolam HCl investigator’s 
brochure, which the sponsor has provided under separate cover to all investigators.
8.2.2
Reporting Procedures
All initial and follow-up SAE reports must be reported by the investigator to the Quintiles 
Transnational Japan K.K., the Shire Global Pharmacovigilance and Risk Management 
Department, and the CRO/Shire medical monitor within 24 hours of the first awareness of the 
event. Note: The 24-hour reporting requirement for SAEs does not apply to reports of abuse, 
misuse, overdose, or medication errors (see Section 8.1.7) unless they result in an SAE. 
The investigator must complete, sign, and date the Shire Clinical Study Serious Adverse Event 
and Non-serious AEs Required by the Protocol Form and verify the accuracy of the information 
recorded on the form with the corresponding source documents (Note: Source documents are not 
to be sent unless requested) and fax or e-mail the form to Quintiles Transnational Japan K.K. and 
the Shire Global Pharmacovigilance and Risk Management Department. A copy of the Shire 
Clinical Study Serious Adverse Event and Non-serious AEs Required by the Protocol Form (and 
any applicable follow-up reports) must also be sent to the CRO/Shire medical monitor using the 
details specified in the emergency contact information section of the protocol.
8.2.3
Serious Adverse Event Definition
An SAE is any untoward medical occurrence (whether considered to be related to investigational 
product or not) that at any dose:

Results in death

Is life-threatening. Note: The term “life-threatening” in the definition of “serious” refers to an 
event in which the subject was at risk of death at the time of the event; it does not refer to an 
event which hypothetically might have caused death if it was more severe.

Requires inpatient hospitalization or prolongation of existing hospitalization. Note: 
Hospitalizations, which are the result of elective or previously scheduled surgery for 
pre-existing conditions, which have not worsened after initiation of treatment, should not be 
classified as SAEs. For example, an admission for a previously scheduled ventral hernia 
repair would not be classified as an SAE; however, complication(s) resulting from a 

Shire
CONFIDENTIAL
Page 47
SHP615-301 Protocol Amendment 2
Midazolam
28 Aug 2017
hospitalization for an elective or previously scheduled surgery that meet(s) serious criteria 
must be reported as SAE(s).

Results in persistent or significant disability/incapacity

Is a congenital abnormality/birth defect

Is an important medical event. Note: Important medical events that may not result in death, 
be life-threatening, or require hospitalization may be considered an SAE when, based upon 
appropriate medical judgment, they may jeopardize the subject and may require medical or 
surgical intervention to prevent 1 of the outcomes listed in this definition. Examples of such 
medical events include allergic bronchospasm requiring intensive treatment in a hospital or at 
home; blood dyscrasias or convulsions that do not result in inpatient hospitalization; or the 
development of drug dependency or drug abuse. 
Hospitalization
For this protocol, hospitalization is defined as any admission to a medical or equivalent 
healthcare facility or any prolongation of an existing admission lasting more than 24 hours.
Admission also includes transfer within the hospital to an acute/intensive care unit (eg, from the 
psychiatric wing to a medical floor, medical floor to a coronary care unit, or neurological floor to 
a tuberculosis unit). A healthcare setting visit does not necessarily constitute a hospitalization; 
however, the event leading to the healthcare setting visit should be assessed for medical 
importance.
Hospitalization does not include the following:

Rehabilitation facilities;

Hospice facilities;

Respite care (eg, caregiver relief);

Same-day surgeries (as outpatient/same-day/ambulatory procedures).
Hospitalization or prolongation of hospitalization in the absence of a precipitating, clinical AE is 
not in itself an SAE. Examples include: 

Admission for treatment of a pre-existing condition not associated with the development of a 
new AE or with a worsening of the preexisting condition (eg, for workup of persistent 
pretreatment laboratory abnormality);

Social admission (eg, subject has no place to sleep);

Administrative admission (eg, for yearly physical examination);

Protocol-specified admission during a study (eg, for a procedure required by the study 
protocol);

Optional admission not associated with a precipitating clinical AE (eg, for elective cosmetic 
surgery);

Hospitalization for observation without a medical AE;

Shire
CONFIDENTIAL
Page 48
SHP615-301 Protocol Amendment 2
Midazolam
28 Aug 2017

Preplanned treatments or surgical procedures. These should be noted in the baseline 
documentation for the entire protocol and/or for the individual subject.
Diagnostic and therapeutic noninvasive and invasive procedures, such as surgery, should not be 
reported as AEs. However, the medical condition for which the procedure was performed should 
be reported if it meets the definition of an AE. For example, an acute appendicitis that begins 
during the AE reporting period should be reported as the AE, and the resulting appendectomy 
should be recorded as treatment of the AE.
8.2.4
Serious Adverse Event Collection Time Frame
All SAEs (regardless of relationship to study) are collected from the time the informed consent is 
signed when the subject with SE arrives at the hospital or healthcare setting, or if the informed 
consent has been previously signed, from the time the subject begins evaluation and treatment in 
the hospital or healthcare setting for SE, until the defined follow-up period stated in Section 7.1.5
and must be reported to Quintiles Transnational Japan K.K., the Shire Global Pharmacovigilance 
and Risk Management Department, and the CRO/Shire medical monitor within 24 hours of the 
first awareness of the event. 
In addition, any SAE(s) considered “related” to the investigational product and discovered by the 
investigator at any interval after the study has completed must be reported to Quintiles 
Transnational Japan K.K. and the Shire Global Pharmacovigilance and Risk Management 
Department within 24 hours of the first awareness of the event.
8.2.5
Serious Adverse Event Onset and Resolution Dates
The onset date of the SAE is defined as the date the event meets serious criteria. The 
resolution date is the date the event no longer meets serious criteria, the date the symptoms 
resolve, or the date the event is considered chronic. In the case of hospitalizations, the 
hospital admission and discharge dates are considered the onset and resolution dates, 
respectively.
In addition, any signs or symptoms experienced by the subject after signing the ICF, or leading 
up to the onset date of the SAE, or following the resolution date of the SAE, must be recorded as 
an AE, if appropriate.
8.2.6
Fatal Outcome
Any SAE that results in the subject’s death (ie, the SAE was noted as the primary cause of 
death) must have fatal checked as an outcome with the date of death recorded as the 
resolution date. For all other events ongoing at the time of death that did not contribute to the 
subject’s death, the outcome should be considered not resolved, without a resolution date 
recorded.
For any SAE that results in the subject’s death or any ongoing events at the time of death, unless 
another investigational product action was previously taken (eg, drug interrupted, reduced, 
withdrawn), the action taken with the investigational product should be recorded as “dose not 
changed” or “not applicable” (if the subject never received investigational product). The 

Shire
CONFIDENTIAL
Page 49
SHP615-301 Protocol Amendment 2

28 Aug 2017
investigational product action of “withdrawn” should not be selected solely as a result of the 
subject’s death. 
8.2.7
Regulatory Agency, Institutional Review Board, and Site Reporting
The sponsor and Quintiles Transnational Japan K.K. are responsible for notifying the relevant 
regulatory authorities/and institutional IRBs of related, unexpected SAEs.
In addition, the sponsor or Quintiles Transnational Japan K.K., is responsible for notifying active 
sites of all related, unexpected SAEs occurring during all interventional studies across the 
SHP615 program.
The investigator is responsible for notifying the local IRB or the relevant local regulatory 
authority of all SAEs that occur at his or her site as required.
8.3
Product Quality Complaints
The product quality includes quality of the drug delivery device combination product. As 
such device defects should be reported according to the instructions in this section. The 
reporting of product quality occurrences, when the product does not meet specifications, 
includes the reporting of device defects. Quality complaints may be reportable to PMDA as a 
device malfunction report, regardless of whether or not the event relates to an AE.
Investigators are required to report investigational product quality complaints to Shire within 
24 hours. This includes any instances wherein the quality or performance of a Shire product 
(marketed or investigational) does not meet expectations (eg, inadequate or faulty closure, 
product contamination) or that the product did not meet the specifications defined in the
application for the product (eg, wrong product such that the label and contents are different 
products). For instructions on reporting AEs related to product complaints.

DATA MANAGEMENT AND STATISTICAL METHODS
9.1
Data Collection
All data collected are to be recorded on the appropriate case report form (CRF).
The authorized site personnel must enter the information required by the protocol on the CRF. A 
study monitor will visit each site in accordance with the monitoring plan and review the CRF 
data against the source data for completeness and accuracy. Discrepancies between source data 
and data entered on the CRF will be addressed by the investigator or qualified site personnel. 
When a data discrepancy warrants correction, the correction will be made by authorized site 
personnel. 
Data collection procedures will be discussed with the site at the site initiation visit and/or at the 
investigator’s meeting. Once a subject is enrolled, it is expected that site personnel will complete 
the CRF entry within approximately 3 business days of the subject’s visit.
9.2
Clinical Data Management
Data are to be entered into a clinical database as specified in the sponsor’s data management 
plan. Quality control and data validation procedures are applied to ensure the validity and 
accuracy of the clinical database.
Data are to be reviewed and checked for omissions, errors, and values requiring further 
clarification using computerized and manual procedures. Data queries requiring clarification are 
to be communicated to the site for resolution. Only authorized personnel will make corrections to 
the clinical database, and all corrections are documented in an auditable manner.
9.3
Data Handling Considerations
All available data will be included in the analysis. No imputation of missing data will be 
performed.
Data from all healthcare setting study sites that participate in this protocol will be combined so 
that an adequate number of subjects will be available for analysis.
9.4
Statistical Analysis Process
The study will be analyzed by the sponsor or its agent. 
The statistical analysis plan (SAP) will provide the statistical methods and definitions for the 
analysis of the efficacy and safety data, as well as describe the approaches to be taken for 
summarizing other study information such as subject disposition, demographics and baseline 
characteristics, investigational product exposure, and prior and concomitant medications. The 
SAP will also include a description of how missing, unused and spurious data will be addressed.

To preserve the integrity of the statistical analysis and study conclusions, the SAP will be 
finalized prior to database lock. All statistical analyses will be performed using SAS
Version 9.3 or higher (SAS Institute, Cary, NC, USA 27513).
9.4.1
Appropriateness of Measurements
This is a Phase 3, open-label study that is designed to evaluate the efficacy and safety of 
MHOS/SHP615 in therapy for subjects with SE or CSE. Measures employed in this protocol are 
standard measures routinely used for the evaluation of the efficacy, safety, and tolerability of an 
investigational product.
9.4.2
General Considerations
For categorical variables, the number and percentage of subjects within each category (with a 
category for missing data as needed) of the parameter will be presented. For continuous 
variables, the number of subjects, mean, median, standard deviation (SD), minimum, and 
maximum values will be presented. Where applicable, estimates from statistical model of least 
squares means, standard errors, and 95% CIs for least squares means will be provided. 
Time-to-event data will be summarized using Kaplan-Meier estimates of the 25th, 50th (median), 
and 75th percentiles with associated 2-sided 95% CIs, as well as percentage of censored 
observations. Plots of the Kaplan-Meier curves and supporting data listings detailing each 
subject’s contribution to the analysis will be provided. 
9.5
Planned Interim Analysis
There is no planned interim analysis for this study.
9.6
Sample Size Calculation and Power Considerations
The target sample size (approximately 25 subjects; minimum 3 subjects per age group) is 
estimated based on the expected response rate which is assumed to be 58.5% compared with the 
threshold of 30% with at least 80% of statistical power at the 2-sided 5% level.
9.7
Study Population
The Screened Set will consist of all subjects who have signed an informed consent.
The Safety Set will consist of all subjects who have received a single dose of MHOS/SHP615.
The Full Analysis Set (FAS) will consist of all subjects who have received a single dose of 
MHOS/SHP615 and who have at least 1 assessment for therapeutic success (cessation of seizure 
within 10 minutes with sustained absence of seizure for 30 minutes) performed after the 
administration of MHOS/SHP615. 
The Pharmacokinetic Set will consist of all subjects who receive a single dose of 
MHOS/SHP615 and for whom at least 1 post-dose PK blood sample was collected.

Efficacy Analyses
The primary efficacy analysis will be conducted on the FAS.
9.8.1
Primary Efficacy Endpoint
The primary efficacy endpoint is response rate, which is defined as the percentage of subjects 
with therapeutic success.

Therapeutic success will be defined as:

the cessation of visible seizure activity within 10 minutes, with

a sustained absence of visible seizure activity for 30 minutes following a single dose of 
MHOS/SHP615.
The primary efficacy analysis will be conducted on FAS by constructing the 2-sided, 95% CI for 
the percentage of subjects reaching therapeutic success. The lower limit of the 95% CI will be 
compared with the threshold of 30%, which is equivalent to comparing the percentage of success 
to the threshold at the 2-sided 5% level of significance.
9.8.2
Secondary Efficacy Endpoints
The secondary efficacy endpoints will include:

Percentage of subjects whose seizure event(s) stopped within 10 minutes of single 
dose of MHOS/SHP615 and who have sustained absence of seizure activity for the at least 
1 hour.

Percentage of subjects whose seizure event(s) stopped within 10 minutes of single 
dose of MHOS/SHP615 and who have sustained absence of seizure activity for at least 
4 hours.

Percentage of subjects whose seizure event(s) stopped within 10 minutes of single 
dose of MHOS/SHP615 and who have sustained absence of seizure activity for the at least 
6 hours.

Time to resolution of seizures (convulsions) 

Time to recovery of consciousness

Percentage of subjects who require additional anticonvulsant medication for ongoing 
SE according to the participating healthcare setting protocol or guideline, 10 minutes after a

significance as determined by the investigator. The number of subjects with a non-missing result, 
and the number and percentage of subjects with a clinically significant result less than the lower 
limit of normal, non-clinically significant result less than the lower limit of normal, within the 
normal range, non-clinically significant result more than the upper limit of normal (ULN), and 
clinically significant result more than the ULN will be summarized by study time point. If more 
than 1 laboratory result is reported per study time point per parameter, the result yielding the 
most severe classification will be selected for analysis. 
Categorical laboratory test results (urinalysis excluding pH) will be summarized by study time 
point. If more than 1 laboratory result is reported per study time point per parameter, the result 
yielding the most severe classification will be selected for analysis. 
Subjects with clinically significant abnormal laboratory test results will be listed. This listing will 
include all results of the laboratory parameter that was abnormal and determined to be clinically 
significant by the investigator for a subject across study time point to identify any trends.
9.9.4
Vital Signs
Vital signs will be summarized using the Safety Set.
Actual values and changes from baseline in vital signs will be summarized. All vital sign data 
will be presented in subject listings.

10.2.3.2 Recording, Access, and Retention of Source Data and Study Documents
Original source data to be reviewed during this study will include, but are not limited to: 
subject’s medical file and original clinical laboratory reports.
All key data must be recorded in the subject’s medical records.
The investigator must permit authorized representatives of the sponsor; the respective national, 
local, or foreign regulatory authorities; the IRB; and auditors to inspect facilities and to have 
direct access to original source records relevant to this study, regardless of media.
The CRA/study monitor (and auditors, IRB or regulatory inspectors) may check the CRF entries 
against the source documents. The ICF includes a statement by which the subject agrees to the 
monitor/auditor from the sponsor or its representatives, national or local regulatory authorities, or 
the IRB, having access to source data (eg, subject’s medical file, appointment books, original 
laboratory reports, X-rays, etc.). 
These records must be made available within reasonable times for inspection and duplication, if 
required, by a properly authorized representative of any regulatory agency (eg, the US FDA, 
EMA, PMDA) or an auditor.
Essential documents must be maintained according to ICH GCP requirements and may not be 
destroyed without written permission from the sponsor.
10.2.3.3 Audit/Inspection
To ensure compliance with relevant regulations, data generated by this study must be available 
for inspection upon request by representatives of, for example, the Japan Pharmaceuticals and 
Medical Devices Agency (PMDA), US FDA (as well as other US national and local regulatory 
authorities), the EMA, the Medicines and Healthcare products Regulatory Agency, other 
regulatory authorities, the sponsor or its representatives, and the IRB for each site.
10.2.3.4 Financial Disclosure
The investigator is required to disclose any financial arrangement during the study and for 1 year 
after, whereby the outcome of the study could be influenced by the value of the compensation for 
conducting the study, or other payments the investigator received from the sponsor. The 
following information is collected: any significant payments from the sponsor or subsidiaries 
such as a grant to fund ongoing research, compensation in the form of equipment, retainer for 
ongoing consultation or honoraria; any proprietary interest in investigational product; any 
significant equity interest in the sponsor or subsidiaries as defined in 21 CFR 54 2(b) (1998).

Ethical Considerations
10.3.1
Informed Consent
It is the responsibility of the investigator to obtain written informed consent from all study 
subjects (parent, guardian, or legally authorized representative) prior to any study-related 
procedures including screening assessments. All consent documentation must be in accordance 
with applicable regulations and GCP. Each subject or the subject’s parent, guardian, or legally 
authorized representative, as applicable, is requested to sign and date the subject informed 
consent form or a certified translation if applicable, after the subject (parent, guardian, or legally 
authorized representative) has received and read (or been read) the written subject information 
and received an explanation of what the study involves, including but not limited to: the 
objectives, potential benefits and risk, inconveniences, and the subject’s rights and 
responsibilities. A copy of the informed consent documentation (ie, a complete set of subject
information sheets and fully executed signature pages) must be given to the subject or the 
subject’s parent, guardian, or legally authorized representative, as applicable. This document 
may require translation into the local language. Signed consent forms must remain in each 
subject’s study file and must be available for verification at any time.
The principal investigator provides the sponsor with a copy of the blank informed consent form
that was reviewed by the IRB and received their favorable opinion/approval. 
A copy of the IRB’s written favorable opinion/approval of these documents must be provided 
to the sponsor prior to the start of the study unless it is agreed to and documented (abiding 
by regulatory guidelines and national provisions) prior to study start that another party (ie,
sponsor or coordinating principal investigator) is responsible for this action. Additionally, if
the IRB requires modification of the sample subject information and consent document 
provided by the sponsor, the documentation supporting this requirement must be provided to the 
sponsor.
10.3.2
Institutional Review Board 
For sites outside the EU, it is the responsibility of the investigator to submit this protocol, the 
informed consent document (approved by the sponsor or their designee), relevant supporting 
information and all types of subject recruitment information to the IRB for review, and all must 
be approved prior to site initiation.
The applicant for an IRB opinion can be the sponsor or investigator for sites within the EU; for 
multicenter studies, the applicant can be the coordinating principal investigator or sponsor, 
according to national provisions.
Responsibility for coordinating with IRBs is defined in the investigator agreement.
Prior to implementing changes in the study, the sponsor and the IRB must approve any revisions 
of all informed consent documents and amendments to the protocol unless there is a subject
safety issue.
Investigational product supplies will not be released until the sponsor has received written IRB
approval of and copies of revised documents.

For sites outside the EU, the investigator is responsible for keeping the IRB apprised of the
progress of the study and of any changes made to the protocol, but in any case at least once a 
year; this can be done by the sponsor or investigator for sites within the EU, or for multicenter 
studies, it can be done by the coordinating principal investigator, according to national 
provisions. The investigator must also keep the local IRB informed of any serious and significant 
AEs.
10.4
Privacy and Confidentiality
The confidentiality of records that may be able to identify subjects will be protected in 
accordance with applicable laws, regulations, and guidelines.
After subjects (parent, guardian, or legally authorized representative) have consented to take 
part in the study, the sponsor and/or its representatives review their medical records and data 
collected during the study. These records and data may, in addition, be reviewed by others 
including the following: independent auditors who validate the data on behalf of the sponsor; 
third parties with whom the sponsor may develop, register, or market MHOS/SHP615; national 
or local regulatory authorities; and the IRB that gave approval for the study to proceed. The 
sponsor and/or its representatives accessing the records and data will take all reasonable 
precautions in accordance with applicable laws, regulations, and guidelines to maintain the 
confidentiality of subjects’ identities.
Subjects are assigned a unique identifying number; however, their initials and date of birth may 
also be collected and used to assist the sponsor to verify the accuracy of the data (eg, to confirm 
that laboratory results have been assigned to the correct subject).
The results of studies – containing subjects’ unique identifying number, relevant medical 
records, and possibly initials and dates of birth – will be recorded. They may be transferred to, 
and used in, other countries which may not afford the same level of protection that applies within 
the countries where this study is conducted. The purpose of any such transfer would include: to 
support regulatory submissions, to conduct new data analyses to publish or present the study 
results, or to answer questions asked by regulatory or health authorities.
10.5
Study Results/Publication Policy
Shire will endeavor to publish the results of all qualifying, applicable, and covered studies 
according to external guidelines in a timely manner regardless of whether the outcomes are 
perceived as positive, neutral, or negative. Additionally, Shire adheres to external guidelines (eg,
Good Publication Practices 2) when forming a publication steering committee, which is done for 
large, multicenter Phase 2-4 and certain other studies as determined by Shire. The purpose of the 
publication steering committee is to act as a non-commercial body that advises or decides on 
dissemination of scientific study data in accordance with the scope of this policy.
All publications relating to Shire products or projects must undergo appropriate technical and 
intellectual property review, with Shire agreement to publish prior to release of information. The 
review is aimed at protecting the sponsor’s proprietary information existing either at the 
commencement of the study or generated during the study. To the extent permitted by the 

Shire

publisher and copyright law, the principal investigator will own (or share with other authors) the 
copyright on his/her publications. To the extent that the principal investigator has such sole, joint 
or shared rights, the principal investigator grants the sponsor a perpetual, irrevocable, 
royalty-free license to make and distribute copies of such publications.
The term “publication” refers to any public disclosure including original research articles, review 
articles, oral presentations, abstracts and posters at medical congresses, journal supplements, 
letters to the editor, invited lectures, opinion pieces, book chapters, electronic postings on 
medical/scientific websites, or other disclosure of the study results, in printed, electronic, oral or 
other form.
Subject to the terms of the paragraph below, the investigator shall have the right to publish the 
study results, and any background information provided by the sponsor that is necessary to 
include in any publication of study results, or necessary for other scholars to verify such study 
results. Notwithstanding the foregoing, no publication that incorporates the sponsor’s 
confidential information shall be submitted for publication without the sponsor’s prior written 
agreement to publish and shall be given to the sponsor for review at least 60 days prior to 
submission for publication. If requested in writing by Shire, the institution and principal 
investigator shall withhold submission of such publication for up to an additional 60 days to 
allow for filing of a patent application.
If the study is part of a multicenter study, the first publication of the study results shall be made 
by the sponsor in conjunction with the sponsor’s presentation of a joint, multicenter publication 
of the compiled and analyzed study results. If such a multicenter publication is not submitted to a 
journal for publication by the sponsor within an 18-month period after conclusion, abandonment, 
or termination of the study at all sites, or after the sponsor confirms there shall be no multicenter 
study publication of the study results, an investigator may individually publish the study results 
from the specific site in accordance with this section. The investigator must, however, 
acknowledge in the publication the limitations of the single-site data being presented.
Unless otherwise required by the journal in which the publication appears, or the forum in which 
it is made, authorship will comply with the International Committee of Medical Journal Editors 
(ICMJE) current standards. Participation as an investigator does not confer any rights to 
authorship of publications.

BIOANALYSIS: SAMPLE HANDLING
1.1
Blood Sample Collection
Blood samples will be collected at the times specified in Table 1 to measure plasma 
concentrations of midazolam, 1-hydroxymidazolam, and any potential additional metabolite(s). 
Blood samples (~1.25 mL) for pharmacokinetic analysis will be drawn by in-dwelling catheters 
or direct venipuncture into K2EDTA tubes, capped, and chilled immediately on crushed ice. The 
actual time that the sample was obtained will be recorded in the subject’s source document and 
on the appropriate CRF page. After applying a tourniquet, venous blood will be drawn with a 
disposable needle. If a catheter is used, the first milliliter of blood on each sampling occasion 
will be discarded. Saline can be used to keep catheters patent.
1.2
Blood/Plasma Sample Handling
Samples should be kept on crushed ice until plasma is separated as soon as possible after
collection (within <15 minutes) by refrigerated centrifugation (4C, 1500 g, 15 minutes). The 
separated plasma will be transferred into appropriately labeled polypropylene tubes via a plastic 
pipette. Plasma to be split in two aliquots: first tube minimum 0.25 mL (primary sample), second 
tube remaining plasma volume (back-up sample).  Aliquots should be shipped separately to the 
bioanalytical laboratory. All samples will be stored at approximately -80C or colder and the 
freezer temperature will be controlled, monitored, and recorded during the storage period until 
they are transferred in the frozen state to a designated bioanalytical contract laboratory. Samples 
will remain frozen at -80C or colder until analysis. Note: For sites that do not have access 
to -80C storage, samples may be stored at -20C for a limited time (maximum 90 days) before
shipping to the bioanalytical CRO.
Plasma sample tubes for bioanalysis must be freezer-safe and identified with freezer-safe labels 
provided by the clinical pharmacology unit. The labels will contain the following information:

Study number

Treatment 

Subject identifier 

Matrix identifier (plasma)

Nominal time
1.3
Shipment of Plasma Samples
Plasma samples should be double bagged to contain leaks and packed with a sufficient quantity 
of dry ice to ensure that they remain frozen for at least 72 hours to allow for delays in shipment. 
All applicable shipping regulations must be followed. Shipments should be scheduled so that no 
samples arrive on the weekend and should be shipped Monday to Wednesday only. 
Samples should be transported to ensure that they arrive at the bioanalytical laboratory between

the hours of 0900 and 1600. The recipient and primary Shire contact must be notified by phone, 
fax, and e-mail when the samples are shipped and must be provided with the shipment tracking 
number. 
Plasma samples, along with the corresponding documentation, will be shipped to:
Name of bioanalytical laboratory: York Bioanalytical Solutions (YBS)
Primary contact: 
Telephone DDI: 
E-mail:
Plasma samples will be stored nominally at -80C prior to and after analysis at York 
Bioanalytical Solutions Limited until their disposal is authorized by Shire.
1.4
Assay Methodology
Drug analysis will be performed at YBS under the guidance of the Department of Nonclinical 
Development, Shire Pharmaceuticals. Plasma sample analysis will be performed according to the 
bioanalytical study plans prepared for the study. 
Plasma samples (K2EDTA) will be analyzed at York Bioanalytical Solutions Limited for 
midazolam, 1-hydroxymidazolam, and any potential additional metabolite(s) using the most 
current validated bioanalytical method. 
In addition, selected plasma samples may be used to investigate incurred sample reproducibility 
(full details will be described in the bioanalytical study plan). The presence of other metabolites 
or artifacts may be monitored or quantified as appropriate.
Raw data will be stored in the archives at York Bioanalytical Solutions Limited.
