Non-Opiate Treatment After Prenatal Opiate Exposure to Prevent Postnatal Injury to the Young Brain

The long term goals of our research are to establish the best pharmacological treatment for NAS and determine how pharmacologic treatment of NAS affects long-term developmental outcomes. The objective of this application is to evaluate the effectiveness of clonidine as a treatment for neonates with NAS, in a randomized clinical trial. Our central hypothesis is that clonidine will effectively treat drug withdrawal manifestations in neonates.

About this study

In this current proposal, the research plan is based on our pilot study, which randomized infants with NAS to receive morphine or clonidine. The treatment groups were similar as to mean birth weight, gestational age, Apgar scores, and postnatal age at treatment. Infants enrolled had no other medical or surgical complications. Treatment was initiated per our NICU standard at the time, and will be continued in this protocol. Total LOS was shorter by about 1 week in the clonidine (mean of 15 days), compared to 21 days in the morphine group.

Aims and Objectives:

To determine whether the treatment of NAS with a non-opiate medication, clonidine, will be more effective than morphine

  • Compare Clonidine and morphine for the treatment of NAS. Compare the efficacy of each drug which is determined by duration of treatment in number of days, number of dose escalations needed to achieve needed treatment, and the need for second drug treatment.
  • Evaluate the neurobehavioral performance scores (habituation, orientation, self- regulation, motor/reflexes, and stress/ abstinence scales) using the neonatal intensive care (NICU) network neurobehavioral scale (NNNS) in both treatment groups. This exam will take place after treatment begins, and at one month post-natal age (38-44 weeks post menstrual age) or at discharge, whichever comes first.

To determine whether treatment of NAS with clonidine will result in better early childhood outcomes than those treated with morphine • Compare the cognitive, motor and behavioral development of children in both treatment groups using the Bayley III Scales of Infant Development at 6 months, one and two years of age.

To build population pharmacokinetic/pharmacodynamic models and determine factors that affect exposure and response to morphine and clonidine

  • Measure blood levels obtained at random times and correlate to Finnegan scores. The pharmacodynamics may help with understanding NAS medications and coping measures in babies.

Primary outcomes

  1. Change in Neurobehavioral Performance Summary Scores From the Neonatal Intensive Care Unit Network Neurobehavioral Scale (NNNS)

    Time frame: Baseline (5-10 days post natal age) and one-month post-natal age (between 4-6 weeks of age), or at discharge, whichever comes first.

    The summary scores from the Neonatal Intensive Care Unit Network Neurobehavioral Scale (NNNS) give a measure of infant neurobehavior in the following areas (score range): habituation (1-9), regulation (2.20-7.50), attention (1.29-8.4), Handling (0-1), quality of movement (1.20-6.20), Non-optimal reflexes (0-12), Asymmetric reflexes (0-7), arousal (2.43-6.67), hypertonicity (0-8), hypotonicity (0-5.0), excitability (0-11), lethargy (0-11.0), and stress/abstinence (0-0.57). A higher score for each item means a higher level of the construct. For example, a higher score for hypertonicity means the infant is more hypertonic and higher score on hypotonicity means the infant is more hypotonic. No cut-off score published for normal or abnormal behavioral performance.

  2. Bayley Scales of Infant and Toddler Development Third Edition

    Time frame: 6 months of life

    Scores obtained Bayley Scales of Infant and Toddler Development Third Edition in the developmental domains of motor, cognitive, and language. This tool for measures of motor, cognitive, and language development is a series of standardized measurements and for each domain, the standardized scores have a mean of 100 and standard deviation of 15 with a range of 55-155 for cognitive and a range of 45-155 for language and motor (lower scores indicating greater impairment). Scores below 1 standard deviation (=or less than 84) is considered below normal. Scores above 1 standard deviation (over 115) represent higher than normal functioning in each domain. The score for each domain (motor, cognitive, and language functioning) represents the composite score.

  3. Bayley Scales of Infant and Toddler Development Third Edition

    Time frame: 1 year of life

    Scores obtained Bayley Scales of Infant and Toddler Development Third Edition in the developmental domains of motor, cognitive, and language. This tool for measures of motor, cognitive, and language development is a series of standardized measurements and for each domain, the standardized scores have a mean of 100 and standard deviation of 15 with a range of 55-155 for cognitive and a range of 45-155 for language and motor (lower scores indicating greater impairment). Scores below 1 standard deviation (=or less than 84) is considered below normal. Scores above 1 standard deviation (over 115) represent higher than normal functioning in each domain. The score for each domain (motor, cognitive, and language functioning) represents the composite score.

  5. Ages and Stages Questionnaire Third Edition (ASQ-3)

    Time frame: 12 months of age

    The ASQ-3 is a developmental screening tool to assess developmental progress in children. Children are scored in the areas of communication, gross motor skills, fine motor skills, problem solving, and personal/social skills. The child's parent/guardian answers whether their child already does an activity (yes=10), sometimes does it (sometimes=5), or does not yet do it (not yet=0). The answers are then used to score each category. Each category is then broken down into whether the child falls above the cutoff (child development is on schedule), close to the cutoff (child development is slightly delayed and requires monitoring/intervention), or below the cutoff (delayed development and further assessment required).

  6. Ages and Stages Questionnaire Third Edition (ASQ-3)

    Time frame: 24 months

    The ASQ-3 is a developmental screening tool to assess developmental progress in children. Children are scored in the areas of communication, gross motor skills, fine motor skills, problem solving, and personal/social skills. The child's parent/guardian answers whether their child already does an activity (yes=10), sometimes does it (sometimes=5), or does not yet do it (not yet=0). The answers are then used to score each category. Each category is then broken down into whether the child falls above the cutoff (child development is on schedule), close to the cutoff (child development is slightly delayed and requires monitoring/intervention), or below the cutoff (delayed development and further assessment required).

  7. Childhood Behavior Checklist (CBCL) T-Scores

    Time frame: Once post discharge (between 18 months up to 24 months of age)

    The CBCL/1.5-5 is validated for children ages 1.5 to 5 years old. It obtains caregivers' ratings of 113 behavior items.

    Scores are broken down into internalizing problems (scores range 29-100, normal is below 60), externalizing problems (scores range from 28-100, normal is below 60), and total problems (range is 28-100, normal is below 60).

    Items are scored on the following syndrome scales: Emotionally Reactive, Anxious/Depressed, Somatic Complaints, Withdrawn, Attention Problems, Aggressive Behavior, and Sleep Problems. Items are also scored on the following DSM-oriented scales: Affective Problems, Anxiety Problems, Pervasive Developmental Problems, Attention Deficit/Hyperactivity Problems, Stress Problems, Autism Spectrum Problems, and Oppositional Defiant Problems.

    The CBCL consists of 113 items, scored on a three-point Likert scale (0=absent, 1= occurs sometimes, 2=occurs often)

Secondary outcomes

  1. Duration of Treatment

    Time frame: 60 days

    Total number days of treatment

  2. Childhood Behavior Checklist 1.5-5 T-Scores

    Time frame: Once post discharge (between 18 months up to 24 months of age)

    On the CBCL 1.5-5, T-scores, with a mean of 50 and a standard deviation of 10, are used to interpret results, with scores of 65 or higher indicating a clinical range, and scores between 60 and 64 suggesting a borderline clinical range.
