Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are pregnant women over 18 years old who are currently taking buprenorphine for opioid use disorder and are enrolled in a prenatal opioid maintenance program.

Probably not a fit

Patients with serious maternal medical illnesses or known major fetal/neonatal congenital abnormalities may not benefit from this study.

What this trial studies

This observational study aims to explore the integration of clinical and genetic factors to identify pregnant women with opioid use disorder (OUD) who may be at risk for poor treatment responses and to assess the potential impact on their infants. The study will involve MRI scans, blood draws, and various assessments during pregnancy and follow-up for up to two years after birth. It plans to enroll 200 mothers with OUD and 100 mothers without a history of opioid use to compare outcomes. The research will focus on the effects of in-utero buprenorphine (Subutex) on both mothers and their infants.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies for pregnant women with opioid use disorder and better health outcomes for their infants.

How similar studies have gone: Other studies have shown success in understanding the effects of opioid use during pregnancy, but this specific approach integrating genetic factors is relatively novel.
