Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
2\. SPECIFIC Aim II: To evaluate the effects of NAS treatment on long-term neurodevelopmental outcome. Infants will be evaluated with development testing at 18 months of age. It is hypothesized that morphine treated infants will have better neurodevelopmental outcomes. It is also hypothesized that neurobehavioral abnormalities identified at two weeks of age will correlate with neurodevelopmental impairment at 18 months.
3: SPECIFIC Aim III: To determine if common genetic variations in the genes involving narcotic action contribute to the severity of NAS. A DNA sample will be obtained from all infants and analyzed for differences in 3 key genes. This will then be correlated with short-term and long-term outcomes.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
2\. SPECIFIC Aim II: To evaluate the effects of NAS treatment on long-term neurodevelopmental outcome. Infants in both treatment groups will be evaluated at 18 months of age using the Bayley III Scales of Infant Development. It is hypothesized that morphine treated infants will have better neurodevelopmental outcomes at 18 months compared to methadone treated infants. It is also hypothesized that neurobehavioral abnormalities (from either treatment group) identified at two weeks of age using the Neonatal Intensive Care Unit (NICU) Network Neurobehavioral Scale (NNNS) will correlate with neurodevelopmental impairment detected with the Bayley III. Early identification of infants at highest risk for impaired development will facilitate therapeutic interventions to improve outcome and decrease resource utilization.
3: SPECIFIC Aim III: To determine if single nucleotide polymorphisms (SNPs) in genes controlling opioid pharmacodynamics contribute to the severity of NAS. SNP genotyping from cord blood or buccal swabs will be obtained from all infants and correlated with short term outcomes (Aim 1) and neurodevelopment assessments (Aim 2) to confirm that genetic variation plays a major role in the severity and outcome of infants with NAS.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Neonatal Morphine Solution
Infants randomized to this arm will receive neonatal morphine solution (0.2mg/mL) for first line therapy. Infants will be scored using the standardized Finnegan scoring system and will be initiated on treatment if they have 2 consecutive scores greater than or equal to 8 or 1 score greater than or equal to 12. Dosing will be weight and symptom based. A "double dummy" design will be used - each infant will be ordered for both a methadone/placebo study drug at 0.4 mg/mL and a morphine/placebo study drug at 0.2 mg/mL. Starting doses will range from 0.3mg/kg/day to 0.9mg/kg/day divided every 4 hours depending on the severity of the Finnegan scores. Doses will be increased to a maximum of 0.9mg/kg/day for continued scores generally \>8 caused primarily by worsening NAS. Infants will be weaned by 10% of the maximum dose once every 24 - 48 hours and the medication will be discontinued once at 25% of the maximum dose.

Doses will be increased to a maximum of 0.9mg/kg/day for continued scores generally \>8 caused primarily by worsening NAS. Infants will be weaned by 10% of the maximum dose once every 24 - 48 hours and the medication will be discontinued once at 25% of the maximum dose.
Phenobarbital
A second line medication will be added once the infant reaches maximum doses of the study drug (morphine or methadone) for continued scores generally \>8. Infants will be loaded with 20mg/kg of phenobarbital with the option to re-load with 10mg/kg q8-12 hours for 2 more doses if needed for continued high scores. Maintenance therapy of 5mg/kg/day will be initiated 12 - 24 hours after the last loading dose. Phenobarbital trough levels will be monitored with goal levels of 20 - 30 mcg/mL.
Phenobarbital will be weaned only after the infant has been weaned off of the study drug. Weaning will begin 48 hours after the study drug has been stopped by 20% of the maximum total daily dose every 3 days for scores \<8. An infant may be discharged home 48 - 72 hours after the first wean. The remaining wean will be outlined in the discharge prescription, and followed up on by study staff with the goal of the phenobarbital discontinuation within a 2 week period.
Methadone
Infants randomized to this group will receive methadone oral solution (0.4mg/mL) for first line therapy. Infants will be scored using the standardized Finnegan scoring system and will be initiated on treatment if they have 2 consecutive scores greater than or equal to 8 or 1 score greater than or equal to 12. Dosing will be weight and symptom based. Starting doses will range from 0.3mg/kg/day to 0.9mg/kg/day divided every 8 hours depending on the severity of the Finnegan scores. To maintain blinding of the two study arms, a "double dummy" design will be used - each infant will receive both methadone/placebo study drug at 0.4 mg/mL and a morphine/placebo study drug at 0.2 mg/mL. Doses will be increased to a maximum of 0.9mg/kg/day for continued scores generally \>8 caused primarily by worsening NAS as needed. Infants will be weaned by 10% of the maximum dose once every 24-48 hours and the medication will be discontinued once at 25% of the maximum dose.
