Brief summary

To evaluate the efficacy, safety, and pharmacokinetics of dexmedetomidine given as continuous IV infusion in pediatric subjects \[≥ 45 weeks CGA (corrected gestational age) to \<17 years old\] requiring sedation under intensive care unit

Interventions

DRUGDexmedetomidine hydrochloride

* 45 weeks CGA to \< 6 years old: Maintenance infusion will be started at 0.2 µg/kg/h. The infusion rate will be adjusted within a range of 0.2 to 1.4 µg/kg/h according to the pediatric subject's sedative state * 6 years old to \< 17 years old: Maintenance infusion will be started at 0.2 µg/kg/h.

Inclusion criteria

1. Subjects whose consent is obtained in writing prior to the clinical trial from a guardian after a full explanation. For subjects over 7 years old, it is desirable that an informed assent is also obtained from the pediatric subject him/herself when possible. 2. Subjects aged ≥45 weeks CGA to \<17 years old at time of consent. No restriction on sex of subject. 3. \[Elective surgical cases\] Subjects classified as American Society of Anesthesiologists (ASA) (ASA physical status classification) Class I to III by preoperative diagnosis. 4. \[Elective surgical cases\] Subjects who require at least 6 hours of respiratory management with intubation under intensive care from immediately after surgery and are anticipated to require sedation. 5. \[Medical ICU cases\] Subjects who require at least 24 hours of respiratory management with intubation under intensive care and are anticipated to require sedation. For medical ICU cases, sedatives used prior to treatment with the investigational product should be discontinued before the start of treatment with the investigational product. 6. If a subject is a female of childbearing potential, she should not be pregnant or possibly pregnant, or lactating.

Exclusion criteria

1. Subjects who are judged by investigator or sub-investigator to have a neurological disease that will make sedation assessment difficult, such as: * Subjects with brain damage which is expected to increase intracranial pressure due to trauma or central nervous system disease * Subjects with cerebral palsy, autism, severe mental retardation, etc. * Subjects with paralysis due to continuous administration of a muscle relaxant or due to a spinal injury of class T5 or higher. 2. Subjects with 2nd or 3rd degree heart block during the tests at the screening visit (excluding subjects using a pacemaker). 3. Subjects with any of the following low blood pressure levels during the tests at the screening visit: * Age ≥ 45 weeks CGA to \< 1 year old: Systolic Blood Pressure (SBP) \<70 mmHg * Age ≥ 1 year old to \< 10 years old: SBP \< 70 + (2 x age in years) mmHg * Age ≥ 10 years old to \< 17 years old: SBP \< 90 mmHg 4. Subject of bradycardia (≤10th centile of heart rate for healthy children) during the physical examination at screening period. 5. Subjects with ALT ≥100 U/L during the laboratory tests at the screening visit. 6. Subjects in whom dexmedetomidine or other alfa 2 receptor agonists, alfa 2 receptor antagonists and drug that may be used in this study are contraindicated. 7. Subjects who may need a sedative or analgesic (including narcotics) other than dexmedetomidine, midazolam or fentanyl during treatment with the investigational product. 8. Subjects who have acute febrile illness \[with a temperature (core or tympanic) ≥ 38.0°Centigrade\] at the screening visit. 9. Subjects who received other investigational product within 30 days before baseline or subjects who will participate in other study that uses an investigational product during the study period. 10. Subjects who received dexmedetomidine within 48 hours before baseline. 11. Subjects who, in the opinion of the investigator or sub-investigator, may be at increased risk to the subject due to the conduct of the study or may have a disease or factor which will probably preclude the obtainment of sufficient study data. 12. Subjects for whom, in the opinion of the investigator or sub-investigator, risks involved with administration of dexmedetomidine outweigh its benefits (e.g., \>2 doses of vasopressor due to cardiogenic shock). 13. Subjects who are investigational site staff members directly involved in the conduct of the study and their family members, site staff members otherwise supervised by the investigator, or subjects who are Sponsor's employees directly involved in the conduct of the study.

Duration of Maintenance of Target Sedation Level After 24 Hours of Dosing of Study Drug Till End of Mechanical Ventilation

Time duration for which the target sedation level was maintained during the specified evaluation period within participants was reported. Target sedation level was analyzed by target sedation scores by using the state behavioral scale (SBS). SBS is a sedation assessment instrument for intubated participants and its score ranges from 2 to -3, where 2= agitated, 1= restless and difficult to calm, 0= awake and able to calm, -1= responsive to gentle touch or voice, -2= responsive to noxious stimuli and -3= unresponsive. During intubation (placement of a flexible plastic tube into the trachea to maintain an open airway or to serve as a conduit through which to administer certain drugs), the target sedation depth by SBS was -2 to 0, where higher score indicated more stability and after extubation (removal of endotracheal tube), the target sedation depth was -1 to 0, where higher score indicated more stability.

Time frame: After 24 hours of study drug dosing till end of mechanical ventilation (up to 28 days)

Number of Participants With Treatment- Emergent Adverse Events (AE) and Serious Adverse Events (SAE)

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent were events between first dose of study drug and up to up to 28 days after end of study drug dosing (up to 56 days) that were absent before treatment or that worsened relative to pretreatment state. AEs included both non-serious adverse events (AEs) and SAEs.

Time frame: Baseline up to 28 days after end of study drug dosing (up to 56 days)

Population: Safety analysis set included all participants who received at least one dose of the investigational product.
