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 | Methadone oral solution (0.4mg/mL) for first line therapy. Infants were scored using the standardized Finnegan Scoring Tool and were initiated on treatment with 2 consecutive scores ≥8 or 1 score ≥12. Dosing was weight and symptom based. Starting doses range from 0.3mg/kg/day - 0.9mg/kg/day divided every 8 hours, depending on the severity of the Finnegan scores. To maintain blinding, a double dummy design was used - each infant received both methadone/placebo study drug at 0.4 mg/mL and a morphine/placebo study drug at 0.2 mg/mL. Doses were increased to a maximum of 0.9mg/kg/day for continued scores generally \>8 caused primarily by worsening NAS, as needed. Infants were weaned by 10% of the maximum dose every 24-48 hours and the medication was discontinued once at 25% of the maximum dose. | 0 | 58 | EG000 |
| Group 2 | Neonatal Morphine Solution | Neonatal morphine solution (0.2mg/mL) for first line therapy. Infants were scored using the standardized Finnegan Scoring Tool and were initiated on treatment with 2 consecutive scores ≥8 or 1 score ≥12. Dosing was weight and symptom based. Starting doses range from 0.3mg/kg/day - 0.9mg/kg/day divided every 4 hrs, depending on the severity of the Finnegan scores. To maintain blinding, a double dummy design was used - each infant received both methadone/placebo study drug at 0.4 mg/mL and a morphine/placebo study drug at 0.2 mg/mL. Doses were increased to a maximum of 0.9mg/kg/day for continued scores generally \>8 caused primarily by worsening NAS, as needed. Infants were weaned by 10% of the maximum dose every 24-48 hours and the medication was discontinued once at 25% of the maximum dose. | 0 | 58 | EG001 |
