Optimizing Pharmacologic Treatment for Neonatal Opioid Withdrawal Syndrome (OPTimize NOW): A Symptom-Based Dosing Approach (OPTimize NOW)

May 13, 2026 updated by: HELP for NOWS Consortium

This clinical trial will help us learn more about how to best care for babies with Neonatal Opioid Withdrawal Syndrome, also called NOWS. Babies with NOWS often have tremors, a hard time sleeping, excessive crying, and trouble feeding. Some babies that have NOWS need medicine. Doctors have two ways of providing medicine that are widely used today:

  1. Scheduled opioid taper approach. The baby gets medicine at regular times. As symptoms get better, the amount of medicine the baby gets decreases until the baby no longer needs medicine. This is called a medicine taper.
  2. Symptom-based approach. The baby will only get medicine when they show signs of NOWS, instead of at regular times. If the baby is showing no signs of NOWS, no medicine will be given.

We are doing the OPTimize NOW study to figure out the best way to give medicine to babies with NOWS.

Study Overview

Detailed Description

This two-period cluster crossover clinical trial will compare the length of time from birth until medically ready for discharge between infants with neonatal opioid withdrawal syndrome (NOWS) who are ≥ 36 weeks' gestation, at risk for pharmacologic treatment, and treated for NOWS with either a symptom-based dosing approach or a scheduled opioid taper approach.

Each study site (i.e., cluster) will be randomized in a 1:1 allocation ratio to one of two sequences:

  • A three-week run-in period followed by a scheduled opioid taper approach for five months (Period 1) followed by a three-week washout period followed by a symptom-based dosing approach for five months (Period 2)
  • A three-week run-in period followed by a symptom-based dosing approach for five months (Period 1) followed by a three-week washout period followed by scheduled opioid taper approach for five months (Period 2)

The randomization scheme will be stratified by the assessment and management approach used at each study site (i.e., Finnegan or Eat, Seep and Console).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: Sequence 1
This sequence will assign eligible participants to a three-week run-in period followed by a scheduled opioid taper approach for five months followed by a three-week washout period followed by symptom-based dosing approach for five months.
During this approach to care, all enrolled infants with NOWS at the study site will be treated with the symptom-based dosing approach if they meet the withdrawal threshold for pharmacologic treatment. Participants may receive up to 3 doses of the study site's preferred opioid during a 24-hour period to treat signs of withdrawal once the threshold for pharmacologic intervention is met. If a 4th dose is required within a 24-hour period, the study site will transition to the scheduled opioid taper algorithm used at the study site to complete the infant's pharmacologic treatment.
During this approach to care, all enrolled infants with NOWS at the study site will be treated with the study site's usual scheduled opioid taper approach, as detailed in each site's treatment algorithm, if they meet the withdrawal threshold for pharmacologic treatment.
