Study summary

The purpose of this mechanistic study is to evaluate the effects that maternal buprenorphine-naloxone maintenance have on the neurobehavioral development of the fetus and infant. To accomplish this, the investigators will study a sample of 120 opioid dependent pregnant women that will receive buprenorphine-naloxone as part of substance abuse treatment at a comprehensive care treatment facility for pregnant and parenting women with substance use disorders. Fetal neurobehavior and maternal physiology will be assessed, via an established maternal-fetal data acquisition system, at 4 points during gestation: 24, 28, 32 and 36 weeks. Infant birth parameters and Neonatal Abstinence Syndrome (NAS) spectrum display will be evaluated at birth, and infant neurodevelopment will be assessed during the first month of life.

Read the detailed description

The project population will be 40 pregnant women with opioid use disorder inducted as outpatients to buprenorphine-naloxone maintenance. Subject treatment data, including medical and obstetric histories, drug use histories, demographic information and psychosocial information will be extracted from patient charts. Weekly urine toxicology testing will provide information regarding other substance use/misuse during the time of study participation. Study participants will undergo 2 60 minute maternal and fetal neurophysiologic monitoring sessions on one day at 4 points during gestation: 24, 28, 32 and 36 weeks, at times of trough (just before sublingual buprenorphine-naloxone or methadone daily dose) and peak (2 1/2 hours after dosing) maternal drug levels. Fetal cardiac (heart rate, heart rate variability, heart rate accelerations) and movement (total fetal movement, number and duration of movement bouts) and the correlation between the two (fetal heart rate-movement coupling) will be determined. Maternal physiologic measures will include heart period and variability, vagal tone, skin conductance and respiratory data. All maternal and fetal measures, with the exception of blood pressure, will be computed in 1-minute intervals and averaged over the 60 min recording. Infant birth data and birth parameters, and neonatal abstinence syndrome scores will be extracted from patient charts. Infants will undergo neurobehavioral testing using the Neonatal Intensive Care Unit (NICU) Network Neurobehavioral Scale, a 30 minute harmless assessment of infant functioning, on days 3, 14 and 30 of life.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 26, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
