The objective of this study is to evaluate the efficacy of a rapid wean intervention compared with a slow-wean intervention in reducing the number of days of opioid treatment from the first dose of weaning to cessation of opioid among infants receiving an opioid (defined as morphine or methadone) as the primary treatment for neonatal opioid withdrawal syndrome (NOWS).
This will be a pragmatic, randomized, blinded trial comparing a rapid-wean intervention (15% decrements from the stabilization dose) to a slow-wean intervention (10% decrements from the stabilization dose) to determine whether rapid weaning will reduce the number of treatment days among infants receiving morphine or methadone orally as the primary treatment for NOWS. Participating hospitals must provide pharmacologic treatment to at least an average of 12 opioid exposed infants each year, use a scoring system to assess for signs of NOWS (original or modified Finnegan Neonatal Abstinence Scoring system, Eat-Sleep or Console), and provide opioid replacement therapy with either morphine or methadone as the primary drug for treating NOWS. Hospitals may change use of these two opioids during the trial period. The investigators will stratify randomization by hospital. The study protocol will commence after NOWS signs have been controlled with an opioid (stabilization) and weaning of pharmacologic treatment is to be started. At or before each 24-hour interval, clinical team members will evaluate and score infants, per hospital practice, for signs of NOWS to determine if the infant will tolerate weaning of the study drug. After study drug cessation, the clinical team will observe infants in the hospital for at least 48 hours prior to discharge, which is similar to clinical practice. A trained examiner will administer the Neonatal Intensive Care Unit (NICU) Network Neurobehavioral Scale (NNNS) to assess neurobehavioral profiles after infants cease study drug and prior to discharge. At one month post discharge, primary caregivers will complete the Brief Symptom Inventory (BSI), the Maternal Postnatal Attachment Questionnaire (MPAQ) and a caregiver questionnaire. The site research team will contact the primary caregiver(s) to update contact information and/or complete questionnaires when the infant is 6 months, 12 months, 18 months, and 24 months of age. The questionnaires will assess infant wellness, neurobehavioral functioning and development, postnatal attachment and bonding, and caregiver well-being. At 24 months, the infants will be seen during which a, certified developmental specialists, blinded to the intervention, will administer the Bayley Scales of Infant and Toddler Development, Fourth Edition (Bayley-4) to assess infant neurodevelopment. The BSI and the Brief Infant Toddler Social Emotional Assessment (BITSEA) will also be administered during the 24 month visit along with measures of growth.
The dose interval for morphine will be either every 3 or 4 hours, per hospital practice. Clinical teams are asked to wean study drug at least every 24 hours.
The dose interval for methadone will be every 8 or 12 hours, per hospital practice. Clinical teams are asked to wean study drug at least every 24 hours.

Days of Opioid Treatment From First Wean to Cessation
The number of days of opioid treatment (used as primary treatment), including escalation, resumption, and spot treatment, from the first weaning dose to cessation of opioid. From the start of opioid study medication until weaning. Infants will exit the study intervention without unblinding (remain in the trial) if they have not weaned off study drug by 35 days (inclusive of the 35th day) form the first weaning dose. Outcome will be truncated at 35 days regardless of the study arm.We note that primary outcome data is missing for 4 participants resulting in total sample of 185 for the primary analysis.
Time frame: From the start of opioid study medication until weaning. Infants exited the study intervention without unblinding (remained in the trial) by 35 days from the first weaning dose. Outcome truncated at 35 days regardless of the study arm.
Days of Opioid Treatment From First Wean to Cessation Among Infants That Were Not Withdrawn in High Enrolling Centers
The number of days of opioid treatment from first wean to cessation among infants that were not withdrawn in high enrolling centers
Time frame: From the start of opioid study medication until weaning. Infants exited the study intervention without unblinding (remained in the trial) by 35 days from the first weaning dose. Outcome truncated at 35 days regardless of the study arm.
