E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
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 pre-specified 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. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate additional efficacy, safety and dosing parameters associated with IV infusion of clevidipine in the study. |

6. Hemophilia or blood coagulation disorders
7. Any serious medical condition which, in the opinion of the investigator, is likely to interfere with study procedures

9. 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
10. Patient is terminally ill (death likely to occur within 48 hours)
11. Use of Methylphenidate, Calcium Channel blockers, Aripiprazole and other atypical anti psychotics and anti-hypertensives used for BP control within 2 hours prior to study drug initiation
12. Positive serum or urine pregnancy test for any female of childbearing potential
13. Participation in other clinical research studies involving the evaluation of other investigational drugs or devices within 30 days of enrollment
14. Patients who, for any reason, are deemed by the Investigator to be inappropriate for this study
15. Patient is a relative of the Investigator or his/her deputy, research assistant, pharmacist, study coordinator, other staff directly involved in the conduct of the study
16. Patients excluded for any of the above reasons may be re-screened for participation at any time if the exclusion characteristic has changed. |

E.5 End points |
E.5.1 | Primary end point(s) |
1. Median time and dose to attain the initial pre-specified target SBP range (minimum of 20 mmHg and a maximum of 40 mmHg apart) during the first 30 minutes of clevidipine infusion
2. Percentage of patients achieving the initial pre-specified target SBP range during the first 30 minutes of clevidipine infusion
3. Pharmacokinetic variables (half-life, area under the curve [AUC], volume of distribution, clearance) established by sparse population methodology
4. Pharmacodynamic variables (relationship between change from baseline in SBP vs. blood concentration and infusion rate)
5. Safety of a prolonged infusion of clevidipine (up to 96 hours) 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 |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
1. Median time obtained, during the first 30 minutes.
2. During the first 30 minutes.
3. PK variables sampling times are prior to start of infusion, during infusion, at end of infusion and 12-24 hours post infusion. See protocol for full details.
4. From 0 to 96 hours
5. Safety up to 96 hours with AEs and SAEs monitored through 7 days. |
|
E.5.2 | Secondary end point(s) |
The percentage of patients who reach the initial pre-specified target SBP range without falling below the lower limit of the pre-specified 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 pre specified target range at any time during the first 30 minutes and at any time during the entire study drug treatment period
Percentage 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
The percentage of patients in whom the SBP is within target range at each hour after the first 30 minute 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

Percent change from baseline in SBP over the first 12 hours post study drug termination |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Secondary end points are assessed during the first 30 minutes of the procedure, with the exception of the patients that require rescue medication (during the first 96 hours) and the percent change in baseline of SBP post study drug termination. |
