Pharmacokinetic Study of Intranasal Dexmedetomidine in Pediatric Patients With Congenital Heart Disease

September 19, 2023 updated by: Kelly Grogan, Children's Hospital of Philadelphia

Dose Escalation Pharmacokinetic Study of Intranasal Atomized Dexmedetomidine in Pediatric Patients With Congenital Heart Disease

The main objectives of the study are to determine peak plasma drug concentration levels and corresponding time of dexmedetomidine following intranasal administration in children age ≥1 mo to ≤ 6 yr with congenital heart disease undergoing an elective diagnostic or interventional cardiac catheterization procedure.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The high anxiety levels that children may experience during the preoperative period may be associated with negative medical, psychological, and social consequences. To reduce this stress, and to facilitate separation from parents and the induction of anesthesia, children are often given a sedative prior to undergoing a procedure. Dexmedetomidine is a highly selective a2-adrenergic receptor agonist with sedative, anxiolytic, and analgesic properties. While off-label in its use, the administration of dexmedetomidine by the intranasal route has become a popular and effective technique for sedation in children because it is non-invasive, easy to administer, well tolerated, and relatively fast in onset. Despite this, little consistent data have been published on its onset time, duration of action, or optimal dose. The only available pharmacokinetic (PK) data on dexmedetomidine in pediatric patients is in children who were administered IV dexmedetomidine. We are proposing a prospective open-label inter-subject cohort dose-escalation pharmacokinetic study to obtain peak dexmedetomidine drug concentration level in plasma and the corresponding time point following intranasal administration in the pediatric patient with cardiac disease.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Time Frame: Subjects were monitored for 6 hours after the administration of study drug.
Dose-limiting toxicities (DLT) include bradycardia, hypotension, new intraventricular conduction abnormality or any serious adverse event possibly, probably, or definitely related to intranasal dexmedetomidine administration that occured after the administration of the intranasal dexmedetomidine and through the completion of PK sampling. Bradycardia, hypotension, or new intraventricular conduction abnormalities that occured after the administration of intravenous dexmedetomidine given by the primary anesthesia team as part of usual clinical care were not considered DLTs but were considered an adverse event. Any events that could not be explained by the intervention that the patient was undergoing were assumed to be related to the study drug.
Subjects were monitored for 6 hours after the administration of study drug.
