Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

Ages Eligible for Study

8 months and older (ADULT, OLDER_ADULT, CHILD)

Accepts Healthy Volunteers

No

Genders Eligible for Study

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.
ACTIVE_COMPARATOR: Phenobarbital
Phenobarbital loading dose 20mg/kg in 2 divided doses, then 5 mg/kg/day divided every 12 hours. Phenobarbital continued throughout the infants hospitalization.
Drug: Phenobarbital
Phenobarbital loading dose 20 mg/kg in 2 divided doses, then 5 mg/kg/day divided every 12 hours. Phenobarbital dose will be adjusted to obtain desired trough of 25 to 30 mcg/mL. Levels will be obtained on Day 6 then weekly thereafter. Phenobarbital will be tapered over 4 weeks upon discharge from the hospital. The standardized taper is based the patient specific dose at the time of discharge.
ACTIVE_COMPARATOR: Clonidine
Clonidine 5 mcg/kg/day divided every 3 hours. Clonidine will be continued to achieve control of NAS symptoms. Clonidine may be weaned after successful discontinuation of oral morphine sulfate. Infants will not be discharged on clonidine.
Drug: Clonidine
Clonidine 5 mcg/kg/day divided every 3 hours. Clonidine will be increased by 1.5 mcg/kg/day to achieve control of NAS symptoms based upon standardized scoring for neonatal abstinence syndrome. Clonidine will be weaned by 25% every 24 hours after successful discontinuation of oral morphine sulfate. Infants will not be discharged on clonidine.

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
Time From Initiation of Adjunctive Therapy Until Hospital Discharge
Time Frame: From date of randomization until hospital discharge, up to 4 months
Number of days from initiation of adjunctive therapy until hospital discharge
From date of randomization until hospital discharge, up to 4 months

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
Length of Stay
Time Frame: From date of randomization until hospital discharge, up to 4 months
Number of days of hospital admission
From date of randomization until hospital discharge, up to 4 months
