Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | 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. | 10 | 58 | OG000 |
| Group 2 | 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. | 17 | 58 | OG001 |

Outcome
- Type
- SECONDARY
- Title
- Number of Infants Needing a Second NAS Medication
- Description
Number of infants treated with a second medication following protocol, phenobarbital. If the Finnegan Score remained elevated (still scored ≥8 two times consecutively, or still scored once ≥12) despite increasing to a predetermined maximal opioid dose (methadone or morphine), phenobarbital was administered (20-mg/kg loading dose followed by 4-5 mg/kg daily).
- Time frame
- Participants were monitored for the duration of their hospitalization, an average of 22 days.
- Population
- Includes infants requiring treatment for NAS who were randomized to either methadone or morphine study intervention. Analysis does not include Standard Clinical Care cohort.
