About this study

Official title: A Phase II, Randomized, Open-Label, Single Center, Pharmacokinetic and Pharmacodynamic Study of Dexmedetomidine in Pediatric Subjects Aged 12 Months Through <24 Months

The purpose of this study is to investigate the pharmacokinetic, pharmacodynamic, and safety of dexmedetomidine at 2 different dose levels in pediatric subjects, aged 12 months through <24 months, administered as an intravenous loading dose followed by continuous infusion for a minimum of 6 hours and up to 24 hours in an intensive care setting.

Read the detailed description

Phase II, randomized, open-label, single-center, study evaluating the pharmacokinetics and pharmacodynamics of dexmedetomidine in pediatric subjects across two dose levels (Dose Level 1 consists of a 0.7 mcg/kg loading dose immediately followed by a 0.5 mcg/kg/hr maintenance infusion; Dose Level 2 consists of a 1.0 mcg/kg loading dose immediately followed by a 0.75 mcg/kg/hr maintenance infusion). The study population will consist of intubated and mechanically ventilated pediatric subjects who require sedation in an intensive care setting for a minimum of 6 hours but not to exceed 24 hours. Subjects eligible for enrollment are 12 months to <24 months of age.

  10. Average Total Faces, Legs, Activity, Cry, and Consolability (FLACC) Score

    FLACC scale is a 5 category observational measure to assess pediatric pain on face, legs, activity, cry and consolability. Responses in each category are scored between 0 to 2 (0 = normal, relaxed to 2 = upset, rigid), for a maximum total score of 10.

    Measured: Prior to loading dose and every hour during the maintenance infusion; within 5 minutes after any fentanyl administration during DEX infusion or every 4 hours in case of continuous fentanyl infusion; within 5 minutes prior and after titration of fentanyl

  11. Absolute Time That Subject is in UMSS Range 2-4 During Treatment Period

    The level of sedation will be assessed using the University of Michigan Sedation Scale (UMSS).

    Score 0 (awake/alert); Score 1 (sleepy/responds appropriately); Score 2 (somnolent/arouses to light stimuli); Score 3 (deep sleep/arouses to deeper physical stimuli); Score 4 (unarousable).

    The UMSS scores obtained just prior the loading dose (LD) and 5 and 10 minutes during LD; 0, 5, 10, 15, 30, and 60 minutes and thereafter every 4 hours of the maintenance infusion; within 5 minutes of obtaining each pharmacokinetic sample; within 5 minutes prior and after any midazolam rescue during dexmedetomidine infusion period.

    Measured: During the treatment (6 to 24 hours)

  12. Number of Subjects Who Received Rescue Medication for Sedation and Analgesic

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Dexmedetomidine in people with Sedation and Pain, run by Hospira, now a wholly owned subsidiary of Pfizer at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Jul 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 24 Jul 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Area Under the Plasma Concentration-time Curve (AUC0-∞) (time frame: 30 minutes prior to loading dose (LD); 5 minutes before finishing LD; 0.5, 1, 2 and 4-6 hours during maintenance infusion (MI); 30 minutes prior (within 24 hours of start of MI) and 10 minutes, 0.5, 1, 2, 4 and 10 hours end of MI). The study lists 12 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jul 2015.
