PROTOCOL SYNOPSIS 
Name of Sponsor/Company:   The Medicines Company 
Name of Finished Product:      Cleviprex® (clevidipine) Injectable Emulsion 
Name of Active Ingredient:      clevidipine 
Title of Study:                            Open label study to assess the efficacy, safety 
and dosing of clevidipine in pediatric patients 
undergoing surgery  
Phase of Development:             IV  
Study Centers:                           2 centers  
Principal Investigator:             Joseph D. Tobias, MD 
Study Period: 
 
Estimated date first subject enrolled:        February 2014 
 
Estimated date last subject completed:     February 2016 
Objectives:  To evaluate the efficacy, safety and dosing of an intravenous (IV) 
infusion of clevidipine for blood pressure (BP) management in pediatric patients 
in the perioperative setting. 
Methodology: Open label study to assess, in a stepwise approach from oldest to 
youngest, the efficacy and safety of clevidipine exposure for a minimum of 30 
minutes and up to a maximum of 96 hours in pediatric patients undergoing a 
surgical procedure requiring anesthesia ≥1 hour, and for whom parenteral IV 
antihypertensive therapy for BP management is expected. 
Number of Patients: 80-100 planned; 80 evaluable for efficacy 
This study will evaluate the efficacy and safety of clevidipine in 80 pediatric 
patients presenting for surgery and anticipated to require BP management during 
the surgical procedure with parenteral IV antihypertensive therapy.  
 
Patients will be enrolled in a stepwise approach, starting with the adolescent 
cohort. An interim analysis of safety and dosing will be performed by the Data 
Safety Monitoring Board (DSMB) before initiation of each of the remaining 
cohorts.  
 Cohort 1: 20 adolescent patients (12 to less than 18 years). 
 Cohort 2: 20 children (2 to less than 12 years, including 10 patients in 
each age group 6 to less than 12 years and 2 to less than 6 years). 
 Cohort 3: 20 infants and toddlers (28 days to less than 24 months). 
 Cohort 4: 20 preterm and newborn infants (0 to less than 28 days).

  Release date: 11 December 2013 
A DSMB will be set up to monitor the safety and dosing data on an ongoing basis 
for all cohorts. Following completion of the adolescent cohort, the DSMB will 
review the safety data and make safety recommendations to the Sponsor 
according to the DSMB Charter. The DSMB review of each completed cohort 
will be required before proceeding to the subsequent cohort to determine if it is 
appropriate to proceed with enrollment of subsequent cohorts and whether an 
adjustment in dosing scheme is required. 
An analysis to confirm appropriate sample size for desired precision will be 
conducted by the Sponsor following complete enrollment of each cohort. 
Diagnosis and Main Criteria for Selection: 
 
Patients will be eligible for inclusion if they satisfy the following criteria: 
 Less than 18 years of age 
 Written informed consent obtained before initiation of any study-related 
procedures 
 The enrolling physician determines that the patient will likely require a 
15% reduction in BP during the perioperative course 
 Intra-arterial line is available for blood pressure monitoring 
 Surgical procedure requiring at minimum of 1 hour of anesthesia, in 
which IV antihypertensive therapy to control BP for at least 30 minutes is 
anticipated 
Patients will be excluded if they present with any of the following exclusion 
criteria: 
 Administration of an IV or oral antihypertensive agent within 2 hours 
prior to study drug administration 
 Congenital heart disease described as single ventricle  
 Evidence of liver failure, severe liver disease, pulmonary disease (e.g., 
uncontrolled asthma), hyperlipidemia, lipoid nephrosis, lipid dysfunction 
or acute pancreatitis 
 Allergy to soya bean oil or egg lecithin 
 Known to be intolerant to calcium channel blockers 
 Hemophilia or blood coagulation disorders 
 Any serious medical condition which, in the opinion of the investigator, is 
likely to interfere with study procedures 
 Clinically significant abnormal physical findings at the screening 
evaluation 
 Any serious surgical or medical condition which, in the opinion of the 
investigator, is likely to interfere with study procedures or with the 
pharmacokinetics or pharmacodynamics of the study drug

implemented. The alternative agent should be chosen per the institutional 
practice. 
The use of an alternative IV antihypertensive agent is discouraged and should be 
limited to situations where it is medically necessary to maintain patient safety as 
determined by the principal investigator.  
If transition from clevidipine to an oral antihypertensive agent is required, at any 
time following administration of the oral antihypertensive agent, the clevidipine 
infusion may be down-titrated or terminated in order to achieve the desired blood 
pressure level. If BP rises to an undesirable level upon cessation of clevidipine 
infusion, additional therapy may be administered or clevidipine infusion may be 
restarted (at initial infusion rate) until successful transition to an oral therapy has 
been achieved. 
If treatment with an IV antihypertensive agent is still required after 96 hours of 
clevidipine therapy, the patient may be transitioned to an alternative IV 
antihypertensive agent according to the institutional standard of care. 
Rescue therapy with IV antihypertensive treatment will be determined by the 
principal investigator per the institutional treatment policy. If a patient is 
receiving rescue therapy with an IV antihypertensive treatment and transition to 
an oral antihypertensive agent is required, institutional practice must be followed. 
Reference Therapy, Dose and Mode of Administration, Batch Number(s):   
There will be no reference therapy in this trial. 
Efficacy Endpoints:  
The primary efficacy endpoints of this trial are: 
 
Median time and dose to attain the initial prespecified target SBP range 
(minimum of 20 mmHg and a maximum of 40 mmHg apart) during the 
first 30 minutes of clevidipine infusion 
 
Percentage of patients achieving the initial prespecified target SBP range 
during the first 30 minutes of clevidipine infusion 
Safety:   
Safety of a prolonged infusion of clevidipine (up to 96 hours) will be assessed 
according to clinical laboratory parameters. Adverse events and serious adverse 
events (SAEs) will be assessed from time of consent through 7 days following 
termination of study drug infusion. 
Pharmacology:

of distribution, clearance) established by noncompartmental analysis or 
sparse population methodology 
 
 
Pharmacodynamic variables (relationship between change from baseline 
in SBP vs. blood concentration and infusion rate) 
The secondary efficacy endpoints of this trial are: 
 
The percentage of patients who reach the initial prespecified target SBP 
range without falling below the lower limit of the prespecified target range 
during the first 30 minutes of clevidipine infusion 
 
The percentage of patients in whom the SBP falls below the lower limit of 
the prespecified target range at any time during the first 30 minutes and at 
any time during the entire study drug treatment period 
 
Percent change in SBP from baseline at each time point during the first 30 
minutes of clevidipine infusion 
 
Percent change from baseline in SBP at each hour after the first 30 
minutes of clevidipine infusion up to the cessation of infusion 
 
Percent change from baseline in SBP over the first 12 hours post study 
drug termination 
 
The percentage of patients in whom the SBP is within target range at each 
hour after the first 30 minutes of clevidipine infusion 
 
Percent change from baseline in heart rate during the first 30 minutes of 
clevidipine infusion and the rest of the treatment period 
 
The percentage of patients who require rescue therapy (i.e., receive any 
alternative IV antihypertensive drug) at any time during study drug 
treatment period, or discontinuation due to adverse events  
 
Statistical Methods: 
The total sample size of 80 evaluable patients is primarily based on clinical 
judgment to provide adequate precision of the findings for this non-comparative 
study. For example, assuming that 90% of patients will achieve the initial target 
SBP range within the first 30 minutes of infusion, a sample size of 80 patients can 
provide a 95% confidence interval with a precision of ±6.6%. This precision will 
become ±7.8% if 85% of patients are assumed to achieve the initial target SBP 
range. The precision will be assessed at the end of each cohort and sample size 
for the next cohort may be adjusted.

Intent-to-Treat (ITT) population: all patients who have received 
clevidipine therapy, and have baseline and at least one post-baseline SBP 
measurements. This will be the primary population used for the efficacy 
analyses. 
PK/PD population: all patients who are dosed with clevidipine and have 
at least one documented and evaluable blood concentration and/or SBP 
observation and documented dose records. Descriptive statistics and 
graphic display will be used to summarize the data collected in the case 
report form for overall and by cohort. Continuous variables will be 
summarized using mean, standard deviation, median, inter-quartile range, 
minimum and maximum. Categorical variables will be summarized using 
frequency and percentage. Time to event variables will be displayed using 
the Kaplan-Meier curve. The dose response relationship will be analyzed 
overall and by cohort.  P-values and/or two-tailed 95% confidence 
intervals will be provided whenever appropriate to demonstrate the 
strength of the findings.

significantly related to increased complications. Basali et al3 reported that patients who 
develop intracranial hemorrhage after craniotomy were more likely to have been 
hypertensive in the intraoperative and early postoperative periods. Therefore, the rationale 
for the treatment of hypertension perioperatively is based on the potential to reduce the risk 
of perioperative mortality and morbidity from both short- and long-term adverse effects.  
Perioperative hypertension in the pediatric patient can be caused by renal failure or 
insufficiency, volume overload, or activation of the sympathetic nervous system. Patients 
with congenital heart disease and intracranial pathology may exhibit a higher likelihood of 
perioperative hypertension, and are more prone to have blood pressure problems with 
potentially more significant adverse outcomes. Once treatable and reversible causes of 
hypertension such as pain, hypercarbia, and hypoxemia are corrected, pharmacologic control 
of BP is indicated. This includes the use of intravenous antihypertensives that reverse the 
sympathetic system’s increase in systemic vascular resistance by producing vasodilation. 
Additionally, controlled hypotension (CH), a deliberate reduction in blood pressure to reduce 
bleeding, transfusion therapy and better visualization of the surgical site, may also be utilized 
during surgery in children. Commonly used agents for both BP control and deliberate 
hypotension in infants and children include sodium nitroprusside (SNP), labetalol, and 
calcium channel antagonists, including nicardipine (NIC). These various pharmacologic 
strategies manifest a number of clinical limitations.  
SNP dilates venous capacitance vessels and decreases preload, causing a decrease in cardiac 
output which predisposes patients to organ ischemia. It is frequently associated with 
tachyphylaxis, reflex tachycardia and, with renal insufficiency or renal failure especially with 
prolonged use, SNP may also cause cyanide toxicity. The potential for excessive hypotension 
and fluctuations in BP necessitate the use of invasive monitoring during administration. 
Labetalol is a mixed alpha and non-specific beta blocker. It has an onset of action of 
approximately 2 to 5 minutes, but also has a long duration of action; estimate from 2 to 4 
hours. Labetalol’s side effects include bradycardia, decreased ventricular function, 
bronchospasm and heart block. Nicardipine (NIC) is a calcium channel blocker with a long 
half-life that makes it difficult to titrate and its BP control action is difficult to reverse.  
The pathophysiology of acute perioperative hypertension and control required during surgery 
require that an antihypertensive agent be arterial-selective, have a rapid onset and offset of 
action, be easy to titrate and have a predictable effect on the reduction of BP [Varon, 20084]. 
Although these above mentioned agents possess some of these characteristics, none possess 
all of them.  
Clevidipine was specifically and intentionally developed to address the limitations of other 
available IV antihypertensive therapies. Clevidipine is a rapidly-acting, vascular-selective, L-
type calcium channel antagonist that lowers arterial blood pressure by reducing systemic 
vascular resistance. Its arterial selectivity allows for BP reduction with no adverse effects on 
heart rate or cardiac output. The quick offset of action is due to rapid metabolism by non-

specific blood and tissue esterases. Efficacy and safety have been well-documented in the 
adult population setting.  
1.2. 
CLEVIDIPINE (CLEVIPREX®) 
Clevidipine is a rapidly-acting, vascular-selective, L-type calcium channel antagonist that 
lowers arterial blood pressure by reducing systemic vascular resistance. It exerts a selective 
vasodilating action on arteriolar resistance vessels, but has no effect on venous capacitance 
vessels. Due to its fast onset and offset of effect on blood pressure, clevidipine can be easily 
titrated, allowing for effective, ongoing BP management. 
1.2.1. 
Preclinical Studies 
Clevidipine is classified as a short-acting, arterial-selective calcium channel antagonist since 
its primary effect is via inhibition of the calcium current in L-type calcium channels. 
Clevidipine is fifty times less potent in inhibiting myocardial contractility than in causing 
vascular smooth muscle relaxation, thereby illustrating that clevidipine is a vascular-selective 
calcium antagonist. At very high concentrations in vitro, clevidipine is more potent in 
inhibiting myocardial contractility than in depressing the spontaneous rate of depolarization 
in the sinus node or in prolonging atrioventricular conduction. Experiments in anesthetized 
dogs show that clevidipine reduces mean arterial pressure (MAP) due to a reduction in SVR, 
and that it does not exert any negative effects on cardiac contractility or conduction in the 
doses tolerated. Clevidipine causes a reflexogenic increase in heart rate in conscious rats and 
dogs but does not affect heart rate in anesthetized animals.  
Clevidipine is rapidly hydrolyzed to its inactive metabolite in blood and extravascular tissues 
in the rat and dog. In experiments with rats, dogs and rabbits, clevidipine demonstrated a 
very short half-life, and reached steady-state blood concentrations within minutes after the 
start of infusion.  
The general pharmacological studies of clevidipine have illustrated that it has a 
natriuretic/diuretic effect when given in a dose that only marginally lowers BP. This effect is 
similar to that of other dihydropyridines. At doses well above the therapeutic level, 
clevidipine inhibits gastrointestinal transport, which is also a characteristic of other calcium 
antagonists. Clevidipine is devoid of direct effects within the autonomic and central nervous 
systems and it does not interfere with neuromuscular transmission or skeletal muscle 
function. Clevidipine has no adverse pharmacological effects on respiratory, liver, or 
endocrine function or on bleeding time. It does not change body temperature.  
In the animal toxicity studies, most findings could be attributed to the lipid content in the test 
formulation. The few effects related to exposure of clevidipine included small biochemical 
differences and organ weight deviations and a slight local irritative vascular effect. Most of 
these findings were related to the dose and/or duration of treatment and satisfactory safety

margins have been established. Study results indicate no clinically relevant risks of 
genotoxicity.

Brochure [Clevidipine Investigator’s Brochure, 20131]. 
1.2.2. 
Clinical Studies 
The clinical development program was comprised of 22 completed clinical studies (4 Phase I, 
10 Phase II, and 8 Phase III studies) [Clevidipine Investigator’s Brochure, 20131]. These 
studies included over 2400 patients overall, of whom 1522 were clevidipine-treated healthy 
subjects or hypertensive patients including the following:  
Four Phase I studies were conducted in 99 healthy volunteers to provide pharmacokinetic 
(PK), pharmacodynamic (PD), and safety/tolerability data. One of these studies, a QT/QTc 
study in 46 healthy volunteers was performed to establish the cardiac electrocardiogram 
(ECG) safety of clevidipine, and to provide further data documenting the tolerability and 
safety of a high therapeutic dose maintained continuously for approximately 24 hours.  
Nine Phase II studies were conducted to obtain preliminary data on the effectiveness of 
clevidipine in 423 patients with hypertension treated in the setting of medical management (3 
studies, 95 patients) or cardiac surgery (6 studies, 337 patients). One of these studies (TMC-
CLV-06-01) was conducted in 61 medical patients with mild to moderate essential 
hypertension to investigate the PK/PD effects and safety of clevidipine during prolonged 
(≥72 hours) continuous infusion. Clinical safety and efficacy data were sufficient to permit 
the design of adequate and well-controlled Phase III studies.  
An additional Phase II study, SPRINT (TMC-CLV-08-02) was completed post FDA 
marketing approval. This was an open-label, single-arm study that evaluated three different 
bolus doses of clevidipine (0.125 mg, 0.25 mg and 0.5 mg), in a total of 30 patients with 
hypertension undergoing elective cardiopulmonary bypass surgery. The study showed that 
clevidipine administered as an IV bolus was effective at rapidly reducing SBP in this 
population of cardiac surgery patients, with evidence of tolerability and a safety profile 
consistent with previous experience in other clinical settings. 
Eight Phase III trials were conducted in a total of 1985 medical, surgical, neurocritical care 
and acute heart failure patients, 1078 of whom received clevidipine. All studies evaluated the 
overall benefit-risk relationship of clevidipine as follows:  
• High-risk surgical patients (N=1720) with perioperative hypertension associated with 
cardiac surgery were treated with clevidipine (N=866), placebo (N=100), or the active 
comparators nitroglycerin (NTG), sodium nitroprusside (SNP), or nicardipine (NIC) 
(total comparator patients N=754) [ESCAPE-1 (TMC-CLV-03-01) and ESCAPE-2 
(TMC-CLV-03-02); ECLIPSE-NTG (TMC-CLV-03-03), ECLIPSE-SNP (TMC-CLV-

03-04), and ECLIPSE-NIC (TMC-CLV-03-05)], all of which were submitted as part of 
the FDA New Drug Application (NDA) submission. 
• High-risk medical patients with severe hypertension requiring BP lowering, most with 
evidence of end-organ dysfunction, presenting to the emergency department were 
treated with clevidipine (N=126) titrated to BP effect followed by at least 18 hours of 
continuous infusion in the VELOCITY trial (TMC-CLV-06-02).  
• High-risk intracranial hemorrhage neurocritical care patients presenting to either the 
emergency department or neuro intensive care unit (ICU) with severe hypertension 
(N=35), and a subset of the total patients with intracranial pressure monitoring (N=7), 
were treated with clevidipine titrated to BP effect in the ACCELERATE trial (TMC-
CLV-07-02). 
• High-risk acute heart failure (AHF) patients presenting to the emergency department 
with severe hypertension and dyspnea (N=85) were treated with clevidipine titrated to 
BP effect in the PRONTO trial (TMC-CLV-08-01). 
The clinical development program included mild-, moderate- and high-risk patient 
populations with respect to demographics, risk variables, and comorbidities. The duration of 
exposure to clevidipine is reflective of clinical practice in the management of patients with 
hypertensive urgencies/emergencies and perioperative hypertension. Patients enrolled in the 
program had high-risk features such as advanced age and comorbidities including myocardial 
ischemia due to coronary artery disease, heart failure, renal and hepatic dysfunction, 
peripheral vascular disease, chronic hypertension and diabetes.  
The PK characteristics of clevidipine and the relationship between PK and PD have been 
studied. The findings demonstrate consistency of PK and PD behavior that is independent of 
infusion duration. Clevidipine has a direct effect and the rapid clearance determines ease and 
predictability of titration to desired effect as well as facilitates transition to oral therapy. No 
specific precautions are necessary with respect to patients with renal or hepatic impairment 
due to the route of metabolism. 
The efficacy of clevidipine has been consistently established in all studies across all 
hypertensive patient populations. Rapid BP lowering effects were observed and a high 
success rate was achieved in titration to the desired BP targets. The appropriateness of the 
recommended dose range (2 mg/h up to 32 mg/h) is supported by the current prescribing 
information [Cleviprex Prescribing Information, December 08, 20118].  
Safety and tolerability has been examined in a large database of high-risk patients with 
multiple comorbidities and end-organ injuries. The safety of the starting dose was confirmed. 
The feasibility of safe use in the emergency room environment was established, in which 
clevidipine was administered by peripheral venous infusion with monitoring of effect by 
sphygmomanometer. No new issues were identified with respect to the incidence of

important clinical outcomes and adverse events (AEs). Subgroup analyses demonstrated 
consistent findings with the overall population analyses.  
Evidence from the Phase III safety program in cardiac surgery patients with perioperative 
hypertension demonstrated an improvement in BP control achieved in patients managed with 
clevidipine compared to two agents commonly used in that setting (NTG and SNP). The 
additional post-hoc finding of an association between BP control and 30-day mortality 
suggests that a parenteral agent providing rapid and tight BP control may improve patient 
outcomes.  
Further details of the clinical studies with clevidipine are provided in the Investigator’s 
Brochure [Clevidipine Investigator’s Brochure, 20131]. 
1.2.3. 
Known and Potential Risks and Benefits 
The lipid formulation of clevidipine has been well tolerated in all clinical studies to date. 
However, if strict aseptic precautions are not followed in the preparation and administration 
of clevidipine, accidental microbial contamination of the vial may occur. Septicemia may 
occur due to microbial growth within the vial contents followed by IV administration. This 
potential risk is mitigated by adherence with the recommended dosing and administration 
guidance provided to all investigators involved in the study.  
Clevidipine contains approximately 0.2 g of lipid per mL (2.0 kcal/8.4 kJ). Lipid intake 
restrictions may be necessary for patients with significant disorders of lipid metabolism. For 
these patients, a reduction in the quantity of concurrently administered lipids may be 
necessary to compensate for the amount of lipid infused as part of the clevidipine 
formulation. Clevidipine is contraindicated in patients with defective lipid metabolism e.g., 
pathologic hyperlipemia, lipid nephrosis and acute pancreatitis if it is accompanied by 
hyperlipidemia. As part of monitoring of this clinical trial, blood chemistry for hepatic and 
pancreatic function will be performed to minimize these risks. 
The most common adverse drug reactions (>2%) for clevidipine observed in patients were 
headache, nausea and vomiting [Cleviprex Prescribing Information, December 08, 20118]. 
1.3. 
STUDY RATIONALE 
Three previously conducted small case series in the perioperative setting have demonstrated 
the effectiveness and safety of clevidipine in the pediatric population aged 11 months to less 
than 18 years of age. These case series included infants and children undergoing surgery for 
repair of congenital heart disease and adolescents requiring controlled hypotension to 
minimize bleeding during spinal surgery. No significant adverse events during treatment 
were observed [Tobias et al6].  
Given these favorable preliminary benefits and considering the limitations of other available 
IV antihypertensive, this study will sequentially determine the dosing including PK/PD,

TRIAL OBJECTIVES AND PURPOSE 
2.1. 
PRIMARY OBJECTIVES  
To evaluate the dosing, efficacy and safety of an intravenous (IV) infusion of clevidipine for 
blood pressure (BP) management in pediatric patients in the perioperative setting. 
This will be accomplished by assessment of the median time and dose to attain a prespecified 
target SBP range during the first 30 minutes of clevidipine infusion, the percentage of 
patients achieving the prespecified range during the first 30 minutes of clevidipine infusion, 
as well as the pharmacokinetic variables established by sparse population methodology and 
pharmacodynamic variables. Safety will be assessed according to clinical laboratory 
parameters. Adverse events and serious adverse events (SAEs) will be assessed from time of 
consent through 7 days following termination of the study drug infusion. 
2.2. 
SECONDARY OBJECTIVES 
To evaluate additional efficacy, safety and dosing parameters associated with IV infusion of 
clevidipine for BP management in pediatric patients in the perioperative setting. 
Additional assessments will include the percentage change in SBP from baseline at each time 
point during the first 30 minutes following initiation of clevidipine infusion.  
Evaluation of efficacy after the initial 30 minute infusion period will include the percent 
change from baseline in SBP at each hour after the first 30 minutes of clevidipine infusion up 
to the cessation of infusion and the percentage of patients in whom the SBP is within target 
range at each hour after the first 30 minutes of clevidipine infusion.  
Safety data will include: 
• 
The percentage of patients who reach the initial prespecified target SBP range without 
falling below the lower limit of the prespecified target range during the first 30 
minutes of clevidipine infusion 
• 
The percentage of patients in whom the SBP falls below the lower limit of the 
prespecified target range at any time during the first 30 minutes and at any time 
during the entire study drug treatment period 
• 
The percent change from baseline in heart rate during the first 30 minutes of 
clevidipine infusion and during the rest of the treatment period; and  
• 
The percentage of patients who require rescue therapy at any time during study drug 
treatment period 
2.3. 
EXPLORATORY OBJECTIVES 
Efficacy will be evaluated in the subgroups of patients with and without pre-existing 
hypertension. Additional analyses may be performed for efficacy and/or safety when 
applicable.

TRIAL DESIGN 
3.1. 
TYPE/DESIGN OF TRIAL 
This study is a Phase IV open-label trial in pediatric patients undergoing elective surgery 
requiring anesthesia ≥1 hour and for whom parenteral IV antihypertensive therapy for BP 
management is expected for at least 30 minutes. Approximately 80-100 patients are planned 
to be enrolled in a stepwise process at 2 centers within 24 months from initiation of the study. 
Patients will be screened between 0 and 7 days before their scheduled surgical procedure. 
Written informed consent by parent or legal guardian and verbal assent by the patient as per 
institutional policy must be provided prior to initiating any study related procedures. All 
eligible patients meeting all inclusion and none of the exclusion criteria will be enrolled to 
receive clevidipine.  
This study will evaluate the dosing, efficacy and safety of clevidipine in 80 pediatric patients 
presenting for surgery and anticipated to require BP management with parenteral IV 
antihypertensive therapy during the surgical procedure.  
Patients will be enrolled in a stepwise approach, starting with the adolescent cohort. An 
interim analysis of safety and dosing of the adolescent cohort will be performed before the 
initiation of remaining cohorts.  
• 
Cohort 1: 20 adolescent patients (12 to less than 18 years). 
• 
Cohort 2: 20 children (2 to less than 12 years, including 10 patients in each age group 
6 to less than 12 years and 2 to less than 6 years). 
• 
Cohort 3: 20 infants and toddlers (28 days to less than 24 months). 
• 
Cohort 4: 20 preterm and newborn infants (0 to less than 28 days). 
A Data Safety Monitoring Board (DSMB) will be set up to monitor the safety and dosing on 
an ongoing basis for all cohorts. Following completion of the adolescent cohort, the DSMB 
will review the safety data and make any safety recommendations according to the DSMB 
Charter to the Sponsor prior to enrolling the remaining cohorts in a sequential order. The 
DSMB review of each completed cohort will be required before proceeding to the subsequent 
cohort to determine if it is appropriate to proceed with enrollment of subsequent cohorts and 
whether an adjustment in dosing scheme is required.  
It is anticipated that there will be 10-20 enrolled patients per pediatric age group whose 
PK/PD parameters will be measured during the first 24-hour period. Up to 10 blood samples 
within the infusion window of 24 hours are planned for PK analysis, with samples taken prior 
to and shortly after infusion start, at least 4-5 samples taken during the infusion period, and 4 
samples taken shortly following termination of infusion.  
Multiple, timed BP measurements are required to be taken prior to and following PK sample 
collection. Accurate and well-timed BP readings will also be necessary to capture the

  Release date: 11 December 2013 
After the first 30-minute treatment period, it may be necessary to alter the desired SBP target 
range over the course of the remaining treatment period. Any changes in the target range will 
be captured in the eCRF.  
Patients who receive alternative intravenous rescue therapy after the first 30 minutes of 
clevidipine may continue in the study. If transition from clevidipine to an oral 
antihypertensive agent is required, the clevidipine infusion may be down-titrated or 
terminated as appropriate to maintain the desired blood pressure. If the BP rises to an 
undesirable level upon cessation of clevidipine infusion, additional therapy may be 
administered or clevidipine infusion may be restarted (and continue until successful 
transition to an oral therapy has been achieved). For patients who receive prolonged 
clevidipine infusions and are not transitioned to other antihypertensive therapies should be 
monitored for the possibility of rebound hypertension for at least 8 hours after the infusion is 
stopped [Cleviprex Prescribing Information, December 08, 20118].  
If treatment with an IV antihypertensive agent is still required after 96 hours of clevidipine 
therapy, the patient will be transitioned to an alternative IV antihypertensive agent according 
to the institutional standard of care. Rescue therapy with IV antihypertensive treatment 
according to the standard of care will be determined by the investigator.  
A DSMB will be set up to monitor the safety and dosing on an ongoing basis for all cohorts.  
The DSMB will review the safety and dosing data from each cohort and make safety and 
dosing recommendations to the Sponsor according to the DSMB Charter prior to enrolling 
the remaining cohorts in sequential order. DSMB review of each completed cohort will be 
required before proceeding to the subsequent cohort. 
In addition, an analysis to assess adequate precision of the efficacy findings will be 
performed at the end of each cohort to ensure that sample size for the following cohort is 
sufficient.

TREATMENT OF PATIENTS 
5.1. 
STUDY MEDICATION 
Clevidipine is being studied for the management of BP in pediatric patients less than 18 years 
of age through preterm and newborn infants undergoing an elective surgery requiring ≥ 1 
hour of anesthesia. 
Clevidipine injectable emulsion (hereafter referred to as clevidipine emulsion) is a single use 
parenteral product that contains a phospholipid emulsion. Clevidipine emulsion may be 
administered via peripheral vein or by central venous infusion employing a volumetric pump. 
The vial containing clevidipine emulsion should be gently inverted several times before use 
to ensure uniformity of the emulsion prior to connecting to the IV tubing. The infusion must 
be administered via a single dedicated line separate from any other medications. However, 
strict aseptic technique should always be used when administering clevidipine emulsion to 
reduce the risk of nosocomial infection. Consistent with the clinical development program to 
date, once the stopper is punctured, a vial must be used within 12 hours and any unused 
portion, including that which is currently being infused, should be discarded.  
5.1.1. 
Clevidipine  
Clevidipine is a dihydropyridine L-type calcium channel blocker developed for the reduction 
of blood pressure (BP) when rapid and predictable control is desired.  
Clevidipine emulsion is intended for intravenous (IV) administration by infusion. Due to the 
rapidity with which clevidipine reduces BP, the dosage and rate of the clevidipine infusion is 
titrated to desired clinical effect.  
Clevidipine is metabolized by hydrolysis in blood and tissues by non-specific carboxyl 
esterases to an inactive compound, which in turn is further, metabolized (mainly by 
glucuronidation) and excreted via the kidneys (~70%). No intact clevidipine is excreted. 
Thus, the metabolic degradation of clevidipine differs from that of other dihydropyridines, 
which are mainly metabolized by the cytochrome P450 system in the liver. 
The high clearance and small volume of distribution result in very short half-lives for 
clevidipine. The half-lives of the two initial rapid phases that account for approximately 95% 
of the area under the curve (AUC) for blood concentration versus time after an IV bolus 
dose, ranged between 0.6 and 0.8 minutes and 2.2 and 2.3 minutes, respectively. The area 
under the terminal phase (half-life = 16–22 minutes) corresponded to between 3.3% and 
5.7% of the total AUC after an IV bolus.  
There is a linear relationship between dose rate and steady state blood concentration of 
clevidipine. The onset of effect is rapid after the start of a clevidipine infusion and the time 
required establishing steady state concentration and effect following an initial infusion or a 
change in administration rate is only 2 to 3 minutes. If the drug is discontinued, recovery of 
effect and return to baseline blood concentrations is rapid. In healthy volunteers, patients

 Clinical Study Protocol MDCO-CLV-12-01

The Medicines Company MDCO-CLV-12-01: Version 3 
  Release date: 11 December 2013 
with essential hypertension (with or without β-blockade) and post-cardiac surgery patients, 
more than a 50% recovery of effect (mean arterial pressure [MAP]) is achieved within 10 
minutes following termination of the infusion.  
Clevidipine reduces arterial BP dose-dependently by reduction of SVR. Clevidipine has no 
effect on central venous pressure. Stroke volume increases primarily as a result of afterload 
reduction with maintained cardiac preload. In post-cardiac surgical patients, a reflexogenic 
increase in heart rate (HR), typical of other antihypertensive therapies, has not been seen with 
clevidipine infusion. Cardiac output is maintained or improved.  
5.1.2. 
Packaging and Labeling  
The Medicines Company, Parsippany, NJ, USA will supply clevidipine emulsion to each 
investigative site packaged in boxes containing four single-use glass vials. Medication labels 
will comply with regulatory requirements. The storage conditions for the medication 
provided will be described on the medication label. 
5.1.3. 
Storage 
Clevidipine emulsion must be stored refrigerated in a secure enclosure at 2-8°C and should 
not be frozen, as specified in the Pharmacy Manual. Access should be strictly limited to the 
pharmacists and their designees or by investigators or designated study personnel if located 
outside of the pharmacy. Neither the pharmacists, investigators nor any designees may 
provide clevidipine to any subject not participating in this protocol and enrolled after full 
subject eligibility has been confirmed. Clevidipine emulsion will be stored in a secure cabinet 
in the Pharmacy or other hospital approved location under the appropriate conditions as 
specified in the Pharmacy Manual. 
5.1.4. 
Accountability 
The investigator or designee must maintain an inventory record of all vials of clevidipine 
emulsion received and all vials administered to assure the regulatory authorities and the 
Sponsor that the investigational drug labeled for use in the pediatric study will not be 
dispensed to any person who is not a patient under the terms and conditions set forth in this 
protocol. Drug accountability forms and/or specific instructions can be found in the 
Pharmacy Manual. 
The clevidipine emulsion supplied for use in this study is to be prescribed only by the 
principal investigator or designated sub-investigators and may not be used for any purpose 
other than that outlined in this protocol. 
During this study, all used (e.g., empty vials) and unused study drug containers will be kept 
until the study monitor has reviewed the drug accountability records. 
Upon study drug inventory and review of the accountability records by the monitor at the end 
of the study, unused clevidipine emulsion will be destroyed onsite based on their drug

destruction policy OR returned to the packaging and labeling facility for destruction. In the 
event that clevidipine emulsion needs to be returned for any other reason, the site will receive 
a written request listing the drug lot number(s) to be returned and the reason for the return 
request. 
5.2. 
CONCOMITANT MEDICATIONS 
5.2.1. 
Required Concomitant Medication(s) 
There are no required concomitant medications for this study. Concomitant medications, 
including anesthetic agents used as part of standard of care, will be recorded in the eCRF per 
the Schedule of Assessments (Section 6.1). 
 
5.2.2. 
Prohibited Concomitant Medications 
The following medications are prohibited and should not be administered to the patient 
within 2 hours prior to receiving treatment with clevidipine: 
1. Methylphenidate 
2. Aripiprazole and other atypical anti-psychotics  
3. Calcium channel blockers  
4. All other antihypertensive agents used for BP control 
This is a study of an IV antihypertensive agent in a pediatric surgical population. Use of non-
study drug medications and treatment procedures that affect the BP are discouraged during 
study drug administration, especially during the initial 30-minute period of study drug 
treatment. It is anticipated that an alternative antihypertensive agent(s) as rescue therapy will 
only be used if the study drug does not adequately lower BP. If a rescue therapy is used, it 
must be recorded in the eCRF, and the reason for such use must be documented. 
 
5.2.3. 
Permitted Concomitant Medication(s)  
1. Oral contraceptives will be permitted during the study for females of child-bearing 
potential 
2. Beta-adrenergic blockers used specifically for reflex tachycardia 
3. Ace inhibitors for volume overload

SCHEDULE AND SEQUENCE OF PROCEDURES 
The Schedule of Assessments (Section 6.1 and Table 1) summarizes the study tests and 
procedures by time point. This study is comprised of three consecutive periods: a screening 
period, a treatment period, and a follow up period. The maximum duration of a patient’s 
participation on study is approximately 18 days (screening up to 7 days, study drug 
administration up to 4 days and follow-up to 7 days). 
The screening period begins from the time patients are consented for elective surgery to 
immediately prior to administration of study drug. The screening period consists of obtaining 
informed consent, confirming patient eligibility and collecting baseline assessments. During 
this period, a medical history (including all medications taken) and a physical examination 
(including height, length and weight) will be performed. Laboratory assessments (Section 
6.3) including a pregnancy test for girls of childbearing potential will be performed. HR and 
BP measurements will be performed. With the exception of the pregnancy test, results of the 
laboratory tests are not required prior to administering study drug.  
Prior to study drug administration, HR and BP measurements will be recorded. These will 
serve as the baseline HR and BP. Once a patient is deemed eligible a prespecified SBP target 
range must be identified prior to initiation of study drug treatment and recorded in the 
patient’s medical record. The target range will later be entered into the eCRF. 
The study drug infusion will commence following: 
• Establishment of stable anesthetic condition (minimal change in anesthetic drug 
concentration and dose) 
• Observation of stable vital signs following skin incision 
The treatment period occurs from initiation of study drug up to 96 hours. This period is split 
into 3 phases for study drug administration. Initial dosing phase from 0 to 1.5 minutes; 
maintenance phase from > 1.5 to 30 minutes up to 96 hours and study drug transition phase 
defined as the transition and/or cessation of infusion.  
BP and HR will be measured and PK samples will be obtained throughout this period. 
Multiple, timed BP measurements are required to be taken prior to and following PK sample 
collection. Accurate and well-timed BP readings will also be necessary to capture the 
patient’s response to infusion rate adjustments during the first 30 minute period and through 
study drug termination.  To accommodate the frequency and precision required for this, 
physiologic blood pressure monitoring will be carried out using a peripheral arterial line, to 
allow for real-time heart rate and BP sampling while obtaining PK samples throughout the 
course of study drug titration and through the follow-up period. It is essential that the clock 
time of infusion pump devices, blood pressure monitors and clocks used to record the time of 
the PK sample be synchronized.

Serum chemistry (Sections 6.1 and 6.3) will be assessed. Concomitant medications, AEs and 
SAEs will be monitored throughout the study period and concludes on day 7 in the follow-up 
period. If appropriate, patients will be transitioned to oral therapy one hour prior to 
termination of clevidipine (Section 6.5.3). 
The follow-up period is divided into these time points following study drug termination: 1 
hour follow-up, 12 hour follow-up, 24 hour follow-up and 7 day follow-up. The 1 hour time 
point starts from discontinuation of study drug until 1 hour (+ 30 minutes) post study drug 
termination. During this period, concomitant medications, serum chemistry, BP, HR and PK 
samples (PK Samples 7, 8, 9, 10 – Table 1) will be obtained and AE and SAEs will continue 
to be monitored and recorded. During the 12 hour time point (+ 30 minutes) period BP, 
concomitant medications, AEs and SAEs will continue to be monitored and recorded. During 
the 24 hour (+ 30 minutes) time point period, concomitant medications, AE and SAEs will be 
monitored and recorded. The 7 day (+1 day) follow-up time point period occurs on day 7 (+1 
day) post study drug termination. The 7 days follow-up will occur by phone (if applicable) to 
monitor and record AE and SAEs.

1 Written informed consent from parent or legal guardian and verbal assent (as per institutional policy) before initiation of any study-related procedures.  
2 Assessment(s) must be performed prior to treatment to determine eligibility for enrollment into the study.  
3 BP (SBP, DBP) and HR are measured using an intra-arterial catheter with electronic transducer. PK Sample1 is to be taken up to 30 minutes prior to start of clevidipine infusion with BP and HR measured, immediately 
followed by PK Sample 1 collection.  Baseline BP and HR are recorded at 60 sec, 45 sec, 30 sec, and 0 sec prior to initiation of clevidipine. PK Sample 2 is taken at 1.5 minutes after the start of clevidipine infusion (before 
first dose titration) with BP and HR measured, immediately followed by PK Sample 2 collection.  The actual time of BP, HR and PK sample must be recorded using devices that are time synchronized. 
4  BP and HR will be recorded every 1.5 minutes (+ 30 second window where a PK sample is required) for a period of at least 30 minutes, every 10 minutes for the next hour, every 30 minutes for the next 2 hours and every 
1 hour until study drug is terminated (up to 96 hours). BP and HR will also be recorded immediately before each PK blood draw (Table 1) is obtained. 
5  If a dose adjustment is indicated, BP and HR should be recorded just prior to each study drug dose change as well as every 1.5 minutes for 15 minutes after the dose adjustment, then return to the BP assessment 
schedule just prior to the dose adjustment.

6  BP and HR will be recorded every 1 hour until study drug has been stopped for 12 hours post-study drug termination.  
7  Clevidipine administered as a continuous IV infusion. 
8  Blood samples for PK analysis will be obtained from an arterial line per the time intervals included in Table 1 below (1 before clevidipine infusion; 4-5 during clevidipine infusion; 4 post clevidipine infusion). NOTE: BP and 
HR will be recorded immediately  before each PK blood draw. The actual time of BP, HR and PK sample must be recorded using devices that are time synchronized.  
9  Beyond the first 30-minute treatment period, it may be necessary to alter the desired SBP target range over the course of the remaining treatment period. Any changes in the target range will be captured in the case report 
form (eCRF). 
10  The 7 day (+1 day) follow-up can occur by phone, if applicable.

GENERAL CONDUCT OF THE TRIAL 
Written informed consent will be obtained for this study by the principal investigator or 
sub-investigator from all patients or parent or legal guardian, with verbal assent obtained 
from children as per Institutional Review Board’s (IRB’s) policy before the performance 
of any protocol-specific procedures. 
Multiple, timed BP measurements are required to be taken prior to PK sample collection. 
Accurate and well-timed BP readings will also be necessary to capture the patient’s 
response to infusion rate adjustments during the first 30 minute period and through study 
drug termination.  To accommodate the frequency and precision required for this, blood 
pressure monitoring will be carried out using a peripheral arterial line, to allow for real-
time heart rate and BP sampling while obtaining PK samples throughout the course of 
study drug titration and through the follow-up period. It is essential that the clock time of 
infusion pump devices, blood pressure monitors and clocks used to record the time of the 
PK sample be synchronized. 
6.3.

Release date 11 December 2013 
Clevidipine infusion may be administered continuously for up to a maximum duration of 
96 hours. Clevidipine may also be terminated at any time for safety reasons. If a dose 
adjustment is indicated, BP and HR should be recorded just prior to each study drug dose 
change as well as every 1.5 minutes for 15 minutes after the dose adjustment 
If the desired BP control effect is not attained using the maximum dose of clevidipine, 
rescue therapy with the use of an alternative IV antihypertensive agent should be 
implemented. Patients who receive rescue therapy along with clevidipine may continue in 
the study. The alternative agent should be chosen per the institutional practice. The use of 
an alternative IV antihypertensive agent is discouraged and should be limited to situations 
where it is medically necessary to maintain patient safety as determined by the principal 
investigator.   
If an additional/alternative IV antihypertensive agent is required, the clevidipine infusion 
may be down-titrated or terminated after initiation of the antihypertensive infusion in 
order to achieve the desired blood pressure level. If a patient is receiving rescue therapy 
with an IV antihypertensive treatment and transition to an oral antihypertensive agent is 
required, institutional practice must be followed. An alternative/additional IV 
antihypertensive agent that is administered as ‘rescue therapy’ will be recorded as rescue 
therapy in the eCRF. The following assessments will be performed during the titration 
and maintenance phase:  
1.5 Minutes – 30 Minutes Post Study Drug Initiation 
• PK Sample 3:  obtain 1.5 minutes after the first dose titration of study drug (taken in 
the order below) 
 BP and HR 
 PK Sample 3 (Table 1), taken immediately following BP and HR 
measurements 
• Then, every 1.5 minutes for the remaining first 30 minutes post-study drug 
initiation: 
 BP and HR 
• PK Sample 4:  obtain once target range is achieved, or at 30 minutes if target range 
is not achieved (taken in the order below): 
 BP and HR 
 PK Sample 4 (Table 1), taken immediately following BP and HR 
measurements 
 BP and HR, taken every 1.5 minutes for the remaining first 30 minutes post-
study drug initiation, as instructed above.

to the end of the first 30 minute period. 
Note:  The actual time of the BP, HR and PK sample should be recorded.  The clocks 
used for these measurements should be synchronized (e.g., when the clock on the BP and 
HR devices reads 13:01, the clock used to record the PK sample should also read 13:01).

HR devices reads 13:01, the clock used to record the PK sample should also read 13:01). 
All assessments above (except PK) should be performed again if clevidipine is 
restarted for any reason. 
6.5.3. 
Transition and Termination Phase, Transition to Oral to 
Study Drug Termination  
For transition to oral therapy, approximately 1 hour prior to the anticipated cessation of 
clevidipine infusion, the oral antihypertensive agent may be administered. At any time 
following administration of the oral antihypertensive agent, the clevidipine continuous IV 
infusion may be down-titrated or terminated in order to achieve the desired blood 
pressure level.  
If treatment with an IV antihypertensive agent is still required after 96 hours of 
clevidipine therapy, the patient may be transitioned to an alternative IV antihypertensive 
agent according to the institutional standard of care. 
If an additional/alternative IV antihypertensive agent is required, the clevidipine infusion 
may be down-titrated or terminated after initiation of the antihypertensive infusion in 
order to achieve the desired blood pressure level. An alternative/additional IV 
antihypertensive agent that is administered as ‘rescue therapy’ will be recorded as rescue 
therapy in the eCRF.  
A PK sample will be taken just prior to discontinuation of study drug. Immediately 
before study drug termination, BP and HR will be measured, immediately followed by 
PK Sample 6, which will be taken from the indwelling arterial line within a 30 second 
window after BP and HR are obtained. 
The following assessments will be performed during transition phase:  
 BP and HR  
- at least every hour until study drug is terminated (up to 96 hours) 
 PK Sample 5:  only taken if transition to an additional antihypertensive is desired 
and concurrent administration at any time >30 minutes and up to 96 hours (taken 
in the order below) 
- BP and HR 
- PK Sample 5 (as applicable): taken immediately after BP and HR and 
before beginning administration of an additional antihypertensive agent  
- BP and HR, taken  as instructed above

6.5.4. 
Follow-Up Period 
The follow-up period is divided into these time points following study drug termination: 
The 1 hour time point is from study drug termination to 1 hour (+ 30 minutes) post study 
drug termination. The 12 hour,  24 hour and 7 day time points occur from 12 hours (+ 30 
minutes), 24 hours (+ 30 minutes) and 7 days (+/- 1 day) post study drug termination, 
respectively. During this phase of the study, 4 PK samples will be taken: PK Sample 7 
taken 0.5 minutes post study drug termination, PK Sample 8 taken at 3 minutes post 
study drug termination, PK Sample 9 taken at 15 minutes post study drug termination and 
PK Sample 10 taken 1 hour post study drug initiation.  For all samples, BP and HR will 
be measured immediately followed by the PK blood draw, which will be taken from the 
indwelling arterial line within a 30 second window after BP and HR are obtained. 
The following assessments will be performed during the Follow-up Period:  
 BP and HR  
o measured at least every 15 min. until study drug has been stopped for 60 
min. then at least every hour until study drug has been stopped for 12

PROTOCOL ASSESSMENTS 
7.1. 
ASSESSMENT OF SAFETY  
7.1.1. 
Adverse Events 
All patients with adverse events (AEs) will be carefully monitored for AE by the 
investigator during the entire study. All AEs and SAE information and the treatment 
provided during the study must be documented in source and will be captured in the 
electronic Case Report Form (eCRF). 
All AEs and SAEs will be assessed and documented from time of consent through 7 days 
post study drug termination. 
Those events that are serious in nature must be reported to The Medicines Company in an 
expedited manner (Section 8 for definitions and reporting requirements). 
Patients experiencing adverse events should be followed clinically until their health has 
returned to baseline status or until all parameters have returned to normal or have 
otherwise been explained. It is expected that the investigator will provide or arrange 
appropriate supportive care for the patient if necessary. 
The AEs will be assessed and reported as detailed in Section 8. The investigator is 
responsible for evaluation and documentation of each AE or SAE occurring during the 
study. The investigator will inform the Sponsor about all AEs, independent of their 
relationship with the study medication. AEs being reported by the patient as well as 
laboratory findings outside normal ranges (e.g., serum chemistry, hematology, urinalysis) 
or other examination results deviating from normal values (e.g., blood pressure, pulse, 
12-lead ECG, etc.), which are considered as clinically relevant by the investigator, must 
be reported to the principal investigator.  
7.2. 
ASSESSMENT OF EFFICACY  
7.2.1. 
Blood Pressure 
7.2.1.1. 
Screening Period 
Screening period is 0-7 days prior to surgery and BP (SBP, diastolic blood pressure  
[DBP]) measured using an intra-arterial catheter with electronic transducer. BP and other 
hemodynamic measurements will be obtained as specified in this protocol. 
7.2.1.2. 
Screening Period immediately prior to study drug 
administration 
BP (SBP, DBP) will be recorded at 60 sec, 45 sec, 30 sec, and 0 sec prior to study drug 
initiation. These BP measurements (SBP, DBP) will serve as the basis for determining 
target SBP range before the start of study drug.

7.2.1.3. 
Initial Dosing Phase 0-1.5 minutes 
BP will be measured at 1.5 minutes post initiation of study drug and prior to the PK 
sample draw. 
7.2.1.4. 
Titration and Maintenance Phase 1.5–30 minutes 
and >30 minutes up to 96 hours 
BP will be measured every 1.5 minutes for a period of 30 minutes and prior to each PK 
sample draw.  
BP will be measured every 10 minutes for the next 1 hour, then every 30 minutes for the 
next 2 hours, at least every 1 hour until the study drug is terminated (up to 96 hours) and 
prior to each PK sample draw. 
If a dose adjustment is indicated, BP and HR should be recorded just prior to each study 
drug dose change as well as every 1.5 minutes for 15 minutes after the dose adjustment.  
7.2.1.5. 
Transition and Termination Phase 
BP will be measured every 1 hour until study drug is terminated (96 hour maximum 
duration of study drug). 
7.2.1.6. 
Follow-up Phase 12 hours after first dose 
BP will be measured at least every 15 minutes until study drug has been stopped for 60 
mins, and then at least every hour until study drug has been stopped for 12 hours. 
7.2.2. 
Concomitant Medication 
The objective of monitoring concomitant medications to control BP is to determine the 
efficacy of clevidipine as monotherapy. 
7.3. 
ASSESSMENT OF PHARMACODYNAMICS  
BP will be measured at the time points specified in Section 7.2.1. Pharmacodynamic 
variables (the changes from baseline in SBP and its relationship with blood concentration 
of clevidipine and infusion rate) will be assessed. 
7.4. 
ASSESSMENT OF PHARMACOKINETICS  
7.4.1. 
Blood Sample Collection 
Blood samples for determination of the blood concentrations of clevidipine and its 
inactive carboxylic acid metabolite M1 (H152/81) will be obtained from an intra-arterial 
catheter distant from the drug administration site, within 30 minutes before initiating 
clevidipine infusion; at 1.5 min post initiation of infusion before dose titration; right 
before the 2nd dose titration; once target BP is reached or at 30 minutes after the initial 
start of clevidipine infusion, whichever comes first; right before transitioning to another 
antihypertensive agent (if applicable); and at a time point just before the infusion

ADVERSE EVENTS  
8.1. 
DEFINITIONS 
8.1.1. 
Adverse Event 
An adverse event (AE) is defined as any untoward medical occurrence in a subject or 
clinical investigation subject administered a medicinal product and which 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 product, whether or not 
considered related to the medicinal product. 
Planned hospital admissions and/or surgical operations for an illness or disease that 
existed before the drug was given or the subject was randomized in a clinical study are 
not to be considered AEs. 
Patients experiencing adverse events should be followed clinically until their health has 
returned to baseline status or until all parameters have returned to normal or have 
otherwise been explained. It is expected that the investigator will provide or arrange 
appropriate supportive care for the subject if necessary. 
8.1.1.1. 
AE severity 
The severity of an AE and the relationship to study drug will be assessed by the 
investigator. The investigator should ensure that any subject experiencing an AE receives 
appropriate medical support until the event resolves. 
Adverse events (AE) will be graded on a 3-point scale and reported as indicated on the 
case report form. The intensity of an AE is defined as follows: 
1 = Mild:  Discomfort noticed, but no disruption to daily activity. 
2 = Moderate:  Discomfort sufficient to reduce or affect normal daily activity. 
3 = Severe:  Inability to work or perform normal daily activity. 
8.1.1.2. 
Study drug causality 
The relationship of an AE to study treatment will be assessed with consideration to the 
following criteria: 
 Temporal relationship to the initiation of study medication 
 Response of the event to withdrawal of study medication 
 AE profile of concomitant therapies 
 Clinical circumstances during which the AE occurred 
 Patient’s clinical condition and medical history

Clinical Study Protocol MDCO-CLV-12-01 
Confidential 
Page 52 
The Medicines Company MDCO-CLV-12-01: Version 3 
Release date 11 December 2013 
Categorization* of causality will be designated by the investigator as stated below: 
1. Unrelated - A clinical event, including laboratory test abnormality, reported as an 
adverse reaction, which lacks a reasonable time sequence between study drug 
administration and the occurrence of the event(s) or for which medical history, 
concomitant medications or other drugs provide a more likely explanation. 
Response to withdrawal of the study drug should not support a relationship 
between the study drug and the event. 
2. Unlikely related - A clinical event, including laboratory test abnormality, with a 
temporal relationship to study drug administration which makes a causal 
relationship improbable, and in which other drugs, chemicals or underlying 
disease provide plausible explanations. 
3. Possibly related - A clinical event, including laboratory test abnormality, with a 
reasonable time sequence to administration of the study drug, which may possibly 
be attributed to concurrent disease or other drugs or chemicals, and which follows 
a clinically reasonable response on withdrawal (de-challenge). Information on 
study drug withdrawal may be lacking or unclear. Re-challenge information is not 
required to fulfill this definition. 
4. Definitely related - A clinical event, including laboratory test abnormality, 
occurring in a plausible time relationship to study drug administration, and which 
cannot be explained by concurrent disease or other drugs or chemicals. The 
response to withdrawal of the study drug (de-challenge) should be clinically 
plausible. The event must be clinically definitive using a satisfactory re-challenge 
procedure if deemed necessary. 
* For the purposes of regulatory reporting, categories ‘3’ and ‘4’ will be considered 
“related.” 
8.1.2. 
Serious Adverse Event 
A serious adverse event (SAE) is any untoward medical occurrence that at any dose: 
 Results in death, 
 Is life-threatening, i.e., the subject was, in the opinion of the investigator, at 
immediate risk of death from the event as it occurred (it does not include an 
event that, had it occurred in a more severe form, might have caused death), 
 Results in a significant, persistent or permanent change, impairment, damage or 
disruption in the subject's body function/structure, physical activities and/or 
quality of life, 
 Requires in-subject hospitalization or prolongs hospitalization, 

Clevidipine 
Clinical Study Protocol MDCO-CLV-12-01

Page 53 
The Medicines Company MDCO-CLV-12-01: Version 3 
Release date 11 December 2013 
 Is a congenital anomaly/birth defect, or 
 Is another medically significant event that, based upon appropriate medical 
judgment, may jeopardize the subject and may require medical or surgical 
intervention to prevent one of the outcomes listed above (e.g., allergic 
bronchospasm requiring intensive treatment in an emergency department or 
home, blood dyscrasias or convulsions that do not result in hospitalization, or 
the development of drug dependency or drug abuse). 
A distinction should be drawn between serious and severe AEs. Severity is an estimate or 
measure of the intensity of an AE, while the criteria for serious AEs are indications of 
adverse subject outcomes for regulatory reporting purposes. A severe AE need not 
necessarily be considered serious and a serious AE need not be considered severe. For 
example, nausea that persists for several hours may be considered severe nausea, but not 
an SAE. On the other hand, a myocardial infarction that may be considered minor could 
also be an SAE if it prolonged hospitalization. 
When death occurs, the cause of death must be reported as an SAE. “Fatal” will be 
reported as the outcome for these events. 
8.1.3. 
Additional Reporting Requirements 
Occurrences of events of overdose, drug misuse and drug abuse are considered 
“important medical events” that should also be reported within 24 hours using 
appropriate reporting form. These events should be reported regardless of their 
association with other adverse events or serious adverse events. 
• 
Abuse of a medicinal product: Persistent or sporadic, intentional excessive use of 
medicinal products which is accompanied by harmful physical or psychological 
effects [DIR 2001/83/EC Art 1(16)]. 
• 
Misuse: Intentional and inappropriate use of a medicinal product not in 
accordance with the prescribed or authorized dose, route of administration, and/or 
the indication(s) or not within the legal status of its supply (e.g., without 
prescription for medicinal products subject to medical prescription). 
• 
Overdose: Administration of a quantity of a medicinal product given per 
administration or per day which is above the maximum recommended dose 
according to the reference safety information for the investigational product or 
comparator as applicable. This also takes into account cumulative effects due to 
overdose.  
8.1.4. 
Reporting Events of Pregnancy 
Occurrences of pregnancy in a study subject or study subject’s partner should also be 
reported within 24 hours using the Pregnancy Reporting Form. In cases where a

Release date 11 December 2013 
pregnancy occurs with a Serious Adverse Event, the SAE Report Form should be used to 
report the SAE and the Pregnancy Reporting Form should be used to report the 
pregnancy. When a pregnancy occurs without any intercurrent SAE, the Pregnancy 
Reporting Form may be submitted alone. The pregnancy must be followed through to 
conclusion. Any pregnancy discovered from the time of consent to follow-up need to be 
reported. 
8.1.5. 
Complications of the Disease Under Study 
Certain symptoms are considered typical outcomes of pediatric surgery and thus are 
expected side effects in pediatric surgery. Clinical events that are considered standard 
post-operative occurrences will be reported as AEs if they are considered untoward or 
unfavorable. In cases where the event is not considered as untoward or unfavorable it 
must be recorded as such in the source document. Consistency in reporting adverse 
events from all participating sites will be ensured through appropriate training and 
monitoring and investigators will be required to report all untoward or unfavorable events 
as adverse events based on their clinical judgment. 
8.2. 
PROCEDURE FOR NON-SERIOUS ADVERSE EVENT RECORDING 
All non-serious AEs that occur from the time of signing informed consent through 7 days 
post study drug termination must be recorded on the source documents and eCRF 
provided by the Sponsor, regardless of causal relationship to study drug. 
8.3. 
PROCEDURE FOR SERIOUS ADVERSE EVENT REPORTING 
All SAEs that occur from consent up to 7 days following study drug termination must be 
reported to The Medicines Company (MDCO) within 24 hours of awareness of the event 
using the provided study specific SAE Report Form. The completion and processing of 
the SAE Report Form (paper or electronic) should be per the instructions in the provided 
SAE Report Form completion guidelines.  In addition to completing the SAE Report 
Form, each SAE must be entered on the appropriate page of the CRF.   
The investigator must assess the causality for each SAE. 
MDCO will contact the investigator, if necessary, to clarify any of the event information. 
The investigator should provide any follow-up information for the event to MDCO as 
soon as it becomes available. 
If the investigator is notified of a SAE that occurs post-study period, that he or she wishes 
to report to the Sponsor (e.g., an event suspected to be causally related to study drug), the 
event should be reported through the process described above.  
Where appropriate, if required by local regulations or procedures, the investigator should 
report these events to the Institutional Review Board (IRB)/Ethics Committee (EC) 
and/or national regulatory authority.

DATA COLLECTION 
An electronic data capture (EDC) system will be used for this trial. All users will be 
trained on the technical features of the EDC as well as the content of the electronic case 
report form (eCRF) by qualified personnel prior to gaining access to the EDC. A 
UserID/Password will be granted after training. This ID is not to be shared amongst the 
study staff. All users must have a unique account to enter or review data. The eCRF 
should be filled out by the site within 5 days after completion of the 24 hour assessment. 
It is not expected that the eCRF will serve as source for any data collected in the trial. If 
there is a reason for a site to do so, it must be approved by the Sponsor and documented 
in the site files. 
Prior to the database being locked, the investigator or designee will review, approve and 
electronically sign/date each completed eCRF. This signature serves as attestation of the 
Investigator’s responsibility for ensuring that all data entered into the eCRF are complete, 
accurate and authentic. After the end of the trial, a copy of the data will be provided to 
the site. This copy will contain the final data, an audit trail of activity on the data, and any 
queries and answers that were posted for data clarification.

STATISTICAL PLAN 
This study is a Phase IV, open-label trial in pediatric patients undergoing an elective 
surgery requiring anesthesia ≥ 1 hour and for whom parenteral IV antihypertensive 
therapy for BP management is expected. Approximately 80-100 patients of 4 cohorts are 
planned to be enrolled at 2 centers from initiation of the project to ensure 80 patients for 
efficacy evaluation. The primary objective of this study is to evaluate the efficacy, safety 
and dosing of an IV infusion of clevidipine for BP management in pediatric patients in 
the perioperative setting. 
A separate Statistical Analysis Plan document will provide more detailed specifications 
in data analysis and presentation. 
10.1. 
SAMPLE SIZE 
The total sample size of 80 (20 per cohort) evaluable patients is considered primarily 
based on clinical judgment to provide adequate precisions of the findings for this non-
comparative study. For example, assuming that 90% of patients will achieve the initial 
target SBP range within the first 30 minutes of infusion, a sample size of 80 patients can 
provide a 95% confidence interval with a precision of ±6.6%. This precision will become 
±7.8% if 85% of patients are assumed to achieve the initial target SBP range. The 
precision will be assessed at the end of each cohort and sample size for the next cohort 
may be adjusted.  
10.2. 
 DEFINITIONS 
10.2.1. 
Patient Study Population 
The following populations will be used for data analyses and/or presentation. 
10.2.1.1. Safety Population  
All patients who received any dose of clevidipine. This will be the primary population 
used for the safety analyses. 
10.2.1.2. Intent-to-Treat (ITT) Population 
All patients who have received clevidipine therapy and have baseline and at least one 
post-baseline SBP measurements. This will be the primary population used for the 
efficacy analyses. 
10.2.1.3. Pharmacokinetics/Pharmacodynamics 
(PK/PD) Population 
All patients who are dosed with clevidipine and have at least one documented and 
evaluable blood concentration and/or SBP observation and documented dose records. 
This will be the primary population for PK/PD analyses.

10.2.2. 
Observational Period 
The observational period for the study will be from the initiation of the study medication 
to 7 days following termination of the study drug. Adverse events and SAEs are to be 
reported from time of signing informed consent up to 7 days following termination of the 
study drug infusion. Any event occurring after the defined observational period, even if 
collected in the eCRF, will not be included in the planned statistical analysis. However, 
all data, including that reported before and after the defined observational period, will be 
included in the data listings. 
10.2.3. 
 Statistical Periods 
The study will occur in three consecutive periods: a screening period, a treatment period, 
and a follow-up period. The Screening Period is 0 to 7 days prior to the initiation of study 
drug (IV clevidipine treatment).  
The Treatment Period occurs from initiation of study drug administration up to 96 hours. 
This period can be split into 3 phases for study drug administration. Initial dosing phase 
from 0 to 1.5 minutes; titration and maintenance phase from >1.5 to 30 minutes and >30 
minutes to 96 hours; transition and termination phase from end of study drug infusion to 
12 hour follow-up.  
The Follow-up Period is divided into 4 time points. The 1 hour time point (+ 30 minutes) 
is from discontinuation of study drug until 1 hour post study drug termination. The 12 
hour time point (+ 30 minutes) is from study drug termination through12 hours post study 
drug termination. The 24 hour time point (+ 30 minutes) occurs from 12 hours post study 
drug termination until 24 hours post study drug termination. The 7 day time point (+ 1 
day) is the final time point in the follow-up period, which occurs from 24 hours post 
study drug termination through day 7. 
10.3. 
STATISTICAL ANALYSES 
All study data will be summarized using descriptive statistics, graphs, and/or data 
listings. Descriptive statistics for continuous variables will include but not limited to 
number of patients (n), mean, standard deviation (SD), median, quartiles (Q1 and Q3), 
minimum (min) and maximum (max) values. Analysis of categorical variables will 
include frequency and percentage. Time to event variables will be analyzed using the 
Kaplan-Meier method.  
No confirmatory hypothesis is established in this study; therefore no formal statistical 
hypothesis testing will be performed. However, p- values and/or two-tailed 95%

Analyses will be presented for overall and by cohort. 
10.3.1. 
Demographic and Background Characteristics 
Patient demographic and background characteristics (including BP and HR recorded prior 
to the first dose of study drug) will be descriptively summarized. Separate analyses will 
be prepared for the safety, ITT, and PK/PD populations. 
10.3.2. 
Efficacy Analysis 
10.3.2.1. Primary Efficacy Endpoints 
The primary efficacy endpoints of this trial are: 
• Median time and dose to attain the initial prespecified target SBP range 
(minimum of 20 mmHg and a maximum of 40 mmHg apart) during the first 30 
minutes of clevidipine infusion 
• Percentage of patients achieving the initial prespecified target SBP range 
during the first 30 minutes of clevidipine infusion 
Median time is the median of the time in minutes between the initiation of study 
medication and time the patient first achieves the initial prespecified target SBP range 
(TBPR) during the first 30 minutes of clevidipine infusion. The median time will be 
summarized using the Kaplan-Meier method. Median time will be estimated with a two-
tailed 95% confidence interval. If patients do not reach TBPR within 30 minutes from the 
initial treatment with study medication, or another intravenous antihypertensive agent is 
administered, the patient will be considered censored at 30 minutes or the time when 
another intravenous antihypertensive agent is given, whichever comes first. 
The percentage of patients achieving TBPR will be calculated using the number of ITT 
patients achieving the endpoint divided by the total number of ITT patients, and 
multiplied by 100.  
Number and percent of patients achieving TBPR during the first 30 minutes along with 
the calculated 95% confidence interval will be presented.  
Analysis of the infusion rate, total dose infused, and total volume infused at the time of 
first achieving TBPR during the first 30 minutes will be summarized descriptively.  
10.3.2.2. Secondary Efficacy Endpoints 
The secondary efficacy endpoints are:  
• The percentage of patients who reach the initial prespecified target SBP range 
without falling below the lower limit of the prespecified target range during 
the first 30 minutes of clevidipine infusion 

Clevidipine 
Clinical Study Protocol MDCO-CLV-12-01

Page 59 
The Medicines Company MDCO-CLV-12-01: Version 3 
Release date 11 December 2013 
• The percentage of patients in whom the SBP falls below the lower limit of the 
pre specified target range at any time during the first 30 minutes and at any 
time during the entire study drug treatment period  
• The percentage of patients in whom the SBP is within target range at each 
hour after the first 30 minute of clevidipine infusion 
• The percentage of patients who require rescue therapy (i.e., receive any 
alternative IV antihypertensive drug) at any time during study drug treatment 
period or discontinuation due to adverse events. 
The percentage of patients reaching each endpoint above will be calculated for overall 
and within each cohort using the number of ITT patients achieving the endpoint divided 
by the number of total ITT patients, and multiplied by 100.  
Number and percent of patients achieving each endpoint during the first 30 minutes along 
with the calculated 95% confidence interval will be presented. 
• Percent change in SBP from baseline at each time point during the 30 
minutes of clevidipine infusion 
• Percent change from baseline in SBP at each hour after the first 30 minutes 
of clevidipine infusion up to the cessation of infusion 
• Percent change from baseline in SBP over the first 12 hours post study drug 
termination 
• Percent change from baseline in heart rate during the first 30 minutes of 
clevidipine infusion and the rest of the treatment period 
Percent change from baseline at each time point specified in above endpoints will be 
calculated for each ITT patient. 
Descriptive statistics will be presented for overall and by cohort. 
10.3.3. 
Safety Analysis 
Safety of a prolonged infusion of clevidipine (up to 96 hours) will be assessed according 
to clinical laboratory parameters. Adverse events and serious adverse events (SAEs) will 
be assessed through 7 days following the termination of the study drug infusion. 
10.3.3.1. Adverse Events 
The Medical Dictionary for Regulatory Activities (MedDRA)  will be used for coding 
adverse events (AEs). An AE (classified as preferred term) occurring during the 
treatment period will be counted as a treatment emergent AE (TEAE) either if it is not 
present at baseline or if it is present at baseline but increased in severity during the 
treatment period.

Page 60 
The Medicines Company MDCO-CLV-12-01: Version 3 
Release date 11 December 2013 
The number and percent of patients reporting TEAEs for each preferred term will be 
tabulated by system-organ class, by system-organ class and severity, and by system-
organ class and relationship to study drug. If more than one event occurred with the same 
preferred term for the same patient, the patient will be counted only once for that 
preferred term using the most severe or related occurrence for the summary by severity, 
or relationship to study drug, respectively. 
Listings will be presented for patients with SAEs/AEs leading to a discontinuation or 
death. 
10.3.3.2. Laboratory Tests 
Laboratory values as well as changes and percent changes from baseline at each time 
point will be summarized. Analyses will also be performed for each laboratory parameter 
on incidence rates of potentially clinical significant (PCS) values for patients without 
PCS value at baseline. 
10.3.3.3. Vital Signs 
Change and percent change from baseline in vital signs will be summarized descriptively 
at each scheduled time point. 
10.3.3.4. Pharmacokinetic Parameters  
Blood concentration versus time data will be analyzed using non-compartmental analysis 
and/or Nonlinear Mixed-Effect Modeling (NONMEM). Following pharmacokinetic 
parameters will be estimated: 
• Maximum observed blood concentration (Cmax) 
• Time to reach Cmax (tmax) 
• Area under the curve of the blood concentration to the last measurable 
concentration (AUClast) 
• Area under the curve of the blood concentration to infinity (AUCinf) 
• Terminal rate constant (λz) and its associated half-life (t1/2) 
• Mean residence time (MRT) 
• Total clearance (CL).  
• Volume of distribution at steady state (Vss) 
• Volume of distribution based in the terminal phase (Vz) 
All concentration data will be presented descriptively at each time point. Descriptive 
statistics comprise N, mean, geometric mean, SD, standard error of mean (SEM), median, 
percent coefficient of variation (%CV), minimum and maximum will be presented for the

pharmacokinetic variables (half-life, area under the curve [AUC], volume of distribution, 
clearance, etc.) established by sparse population methodology. 
10.4. 
INTERIM ANALYSIS 
Following completion of the adolescent cohort, the DSMB will review the safety data and 
make safety recommendations to the Sponsor according to the DSMB Charter prior to 
enrolling the remaining cohorts in sequential order. DSMB review of each completed 
cohort will be required before proceeding to the subsequent cohort to determine if it is 
appropriate to proceed with enrollment of subsequent cohorts and whether an adjustment 
in dosing scheme is required. 
In addition, an analysis to assess adequate precision of the efficacy findings will be 
performed at the end of each cohort to ensure that sample size for the following cohort is 
sufficient.  
10.5. 
EXPLORATORY ANALYSIS 
Efficacy assessments in patients with and without pre-existing hypertension will be 
performed. Additional analyses may be performed for efficacy and/or safety when 
applicable.
