Dexmedetomidine Use in Infants Undergoing Cooling Due to Neonatal Encephalopathy (DICE Trial) (DICE)

February 13, 2026 updated by: Mariana Baserga, University of Utah
Management of neonatal pain and sedation often includes opioid therapy. A growing body of evidence suggests long-term harm associated with neonatal opioid exposure. Providing optimal sedation while neonates are undergoing therapeutic hypothermia (TH) may be beneficial but also presents therapeutic challenges. While there is evidence from animal models of brain injury and clinical trials in adults to support the safety and neuroprotective properties of dexmedetomidine (DMT), there are no published large clinical trials demonstrating safety and efficacy of DMT use in neonates with hypoxic-ischemic encephalopathy (HIE) during treatment with TH. This study is innovative in proposing a Phase II, 2-arm trial providing the opportunity to evaluate the use of DMT as compared to the use of morphine for sedation and pain management for babies undergoing TH. We propose to confirm optimal DMT dosing by collecting opportunistic pharmacokinetics (PK) data and determine safety of DMT in this population. These data will inform a larger phase III efficacy trial.

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.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Dexmedetomidine (DMT)
Subjects randomized to DMT arm in a 1:1 ratio. A loading dose of 1 mcg/kg will be given followed by 0.1 to 0.5 mcg/kg/h continuous infusion. The Neonatal Pain, Agitation, and Sedation Scale (N-PASS) will be used to determine infusion rate.
Drug: Dexmedetomidine Hydrochloride
Potent α2-adrenergic receptor agonist that provides sedation, analgesia, and prevents shivering but does not suppress ventilation.
Active Comparator: Morphine
Subjects randomized to morphine in a 1:1 ratio. Intermittent dosing every 3-4 hours of 0.02-0.05 mg/kg/dose or continuous infusion of 0.005 to 0.01 mg/kg/hr. The N-PASS will be used to determine dosing and frequency.
Drug: Morphine Sulfate
Opioid agonist that provides analgesia, pain management and sedation and may suppress ventilation.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Examine Safety Measures in Infants Receiving DMT to Those Receiving Morphine
Time Frame: First 96 hours of life
Safety will be evaluated during the first 4 days of life by comparing number of serious adverse events between two study arms.
First 96 hours of life

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
DMT Plasma Levels
Time Frame: one week
Two opportunistic PK samples (at time of routine laboratories) and a PK sample any time there is an adverse event will be obtained for measurement of DMT plasma concentrations as needed. Because these PK samples are done opportunistically, there are no pre-set defined time points for PK measurements.
one week

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.

Generalized Motor Assessment Scores at 3-4 Months of Age
Time Frame: 3-4 months of age
the GMA is a validated test that aids in early detection of neurological movement disorders by evaluating the quality of movements during a 2-minute video. Certified assessors will grade the quality of movements which include: normal writhing, poor repertoire, cramped synchronized, and chaotic movements. All movements other than normal writhing are considered atypical. The results will be compared between the two drug treatments.
3-4 months of age
Hammersmith Infant Neurological Exam (HINE) Scores at 3-4 Months of Age
Time Frame: 3-4 months of age
The HINE is a 26 item exam that assesses different aspects of neurological function and these scores will be compared between the two drug treatment regimens. This assessment scores 5 different neurological development areas: Cranial nerve function, posture, movements, tone, and reflexes/reactions. The maximum score is 78 and lowest score is 0. Higher scores show better neurological development consistent with better outcomes.
3-4 months of age
Hammersmith Infant Neurological Exam (HINE) Scores at 6-9 Months of Age
Time Frame: 6-9 months of age
The HINE is a 26 item exam that assesses different aspects of neurological function and these scores will be compared between the two drug treatment regimens. This assessment scores 5 different neurological development areas: Cranial nerve function, posture, movements, tone, and reflexes/reactions. The maximum score is 78 and lowest score is 0. Higher scores show better neurological development consistent with better outcomes.
6-9 months of age
Test of Infant Motor Performance (TIMP) Scores at 3-4 Months of Corrected Age
Time Frame: 3-4 months of corrected age
This test evaluates posture and motor control and is designed to be used specifically in infants born prematurely. Results are given based on z-scores from normative values and are given as low average, below average, and far below average. Lower scores are more predictive of worse outcomes. These scores will be compared between the two drug treatment regimens.
3-4 months of corrected age
Peabody Developmental Motor Skills (PDMS-2) at 6-9 Months of Age
Time Frame: 6-9 months of age
This test evaluates fine motor, gross motor, and total motor skills. Results are converted to age equivalent rating and then quotient scores are given for each category. Minimum is 35 and maximum is 165. The average score is 90-110, with higher scores given in 3 SD above average performance and lower scores given in 3 SD below average performance.The higher the score, the better predicted outcome. These scores will be compared between the two drug treatment regimens.
6-9 months of age
Ages and Stages Questionnaire at 6-9 Months of Age
Time Frame: 6-9 months of age

Parental survey that assesses communication, gross and fine motor skills, and social behaviors. Scores range from 0-60, and the higher the score, the better the outcome.

These scores will be compared between the two drug treatment regimens
