E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study was to characterize the safety and efficacy of
Dexmedetomidine (DEX) administered as an intravenous (IV) loading dose followed by a continuous IV
infusion in preterm subjects, ages ?_ 28 weeks through < 36 weeks gestational age. |
|
E.2.2 | Secondary objectives of the trial |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Initially intubated and mechanically ventilated pediatric subjects in an intensive care setting
anticipated to require at least 6 hours of continuous IV sedation.
2. Age: subjects had to be in the following age range at screening:
Preterm subjects z 28 weeks through < 36 weeks, gestational age;
Note: Gestational age (in weeks) was calculated as follows: the time elapsed between the first
day of the last menstrual period and the day of enrollment. 14
3. Weight: subject's weight at the time of enrollment had to be > 1000 g.
4. Subject's parent(s) or legal guardian(s) had voluntarily signed and dated the informed consent
document approved by the IRB/ IEC. |
|
E.4 | Principal exclusion criteria |
1. Neonate subjects with neurological conditions that prohibited an evaluation of sedation such as:o Diminished consciousness from increased intracranial pressure.
O The presence of catastrophic brain injury or other severe mental disorders that would make
responses to sedatives unpredictable and/or measurement of the N-PASS unreliable.
O Subjects with immobility from neuromuscular disease or continuous infusion of
neuromuscular blocking (NMB) agents.
2. Subjects with second degree or third degree heart block unless subject has a pacemaker or
pacing wires were in situ.
Note: If subject's status-post Cardiopulmonary Bypass (CPB) was being managed without
pacing wires in situ, the subject could not have been suspected to be in second degree or
third degree heart block at the time of DEX administration.
3. HR < 120 bpm prior to the initiation of DEX.
4. Exposure to any investigational drug within 30 days prior to DEX administration.
5. Previous exposure to DEX as part of an investigational study.
6. In subjects that were ex-utero for less than 72 hours, a maternal history of poly-substance drug
abuse, based upon the Investigator's clinical judgment.
7. At the discretion of the Investigator, subjects in whom the risk of DEX treatment was expected to
exceed its benefits.
8. Subjects who had a known allergy or contraindication to fentanyl, morphine, MDZ, DEX, or other
a-2 agonists.
9. Requirement for medications other than DEX, MDZ, morphine, or fentanyl for sedation and pain
control.10. Screening Alanine Aminotransferase (ALT) levels > 115 UIL. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoint for the study was the frequency of subjects requiring any use of rescue
medication, midazolam (MDZ), for sedation during DEX infusion |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Each subject received a 10- or 20- minute loading dose infusion of DEX followed
by a continuous fixed maintenance dose infusion of DEX for at least 6 hours but not more than 24 hours. |
|
E.5.2 | Secondary end point(s) |
Incidence of rescue medication use (fentanyl or morphine) for analgesia during DEX infusion
° Amount of rescue medication (MDZ) for sedation during DEX infusion
• Amount of rescue medication for analgesia during DEX infusion
° Change from baseline in vital signs (heart rate, blood pressure, mean arterial pressure), respiratorySafety:
• the incidence of AEs
° Changes from baseline in vital signs
° Changes from screening in clinical laboratory tests
° Changes in input/output fluid balance
0 Changes from baseline in ECG
° Use of rescue regimens to support vital signs
° Use of adjunct medications
rate and oxygen saturation measures during DEX infusion
0 Time spent with a total N-PASS score >3 during DEX infusion
° Time to extubation was explored in DEX-exposed subjects |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Each subject received a 10- or 20- minute loading dose infusion of DEX followed
by a continuous fixed maintenance dose infusion of DEX for at least 6 hours but not more than 24 hours. |
