About this study

Official title: NIDA CTN Protocol 0080: Medication Treatment for Opioid Use Disorder in Expectant Mothers (MOMs): a Pragmatic Randomized Trial Comparing Extended-release and Daily Buprenorphine Formulations: Conceptual Model Assessments (CMA) Sub-study

This is a sub-study of NIDA CTN Protocol 0080: Medication Treatment for Opioid Use Disorder in Expectant Mothers (MOMs; Unique protocol ID: 2019-0429-1). Participants in MOMs will be offered the opportunity to enroll in this sub-study, which is designed to evaluate conceptual models of the mechanisms by which extended-release buprenorphine (BUP-XR), may improve mother-infant outcomes, compared to sublingual buprenorphine (BUP-SL). The additional data collected in this sub-study will be combined with data from the main MOMs trial.

It is hypothesized that: (1) the buprenorphine blood levels will vary, depending on which formulation of buprenorphine was received, (2) the variation in buprenorphine blood levels will be associated with fetal behavior (including fetal heart rate variability) (3) the variation in buprenorphine blood levels will be associated with differences in mother outcomes (including medication adherence and illicit opioid use) (4) the variation in buprenorphine blood levels and in fetal behavior will be associated with infant outcomes (including neonatal opioid withdrawal syndrome and infant development).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Buprenorphine InjectionDrug

    Also called CAM2038

    Weekly and monthly formulations of injectable, extended-release buprenorphine (BUP-XR).

  • Buprenorphine Sublingual ProductDrug

    Also called Subutex, Suboxone

    Sublingual buprenorphine (BUP-SL), administered daily.

Study groups in NCT03911466
Study groupRoleWhat they receive
BUP-XRWeekly subcutaneous Buprenorphine Injection (CAM2038) during pregnancy. During the 12-month postpartum phase, participants who are breastfeeding will continue receiving subcutaneous Buprenorphine Injection weekly; participants who are not breastfeeding will receive subcutaneous Buprenorphine Injection monthly. The target doses will be 24 mg for the weekly formulation and 96 mg for the monthly formulation, but the actual dose may be lower or higher as determined by the prescribing clinician (e.g., based on craving/withdrawal experienced by the participant, etc.).
Receives: Drug: Buprenorphine Injection
BUP-SLDaily sublingual buprenorphine, with or without naloxone, based on site preference, during pregnancy and during the 12-month postpartum phase. The target dose will be 16 mg daily, but the actual dose may be lower or higher as determined by the prescribing clinician (e.g., based on craving/withdrawal experienced by the participant, etc.).
Receives: Drug: Buprenorphine Sublingual Product

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cmin of buprenorphine and metabolites in plasma

    A blood draw at the estimated time of minimum drug concentration ("trough") to evaluate adequacy of dose for the conceptual model.

    Measured: 2 weeks post-randomization

  2. Cmin of buprenorphine and metabolites in plasma

    A blood draw at the estimated time of minimum drug concentration ("trough") to evaluate adequacy of dose for the conceptual model.

    Measured: 4 weeks post-randomization

  3. Fetal heart rate variability

    This is the measure of primary interest from the fetal evaluation (non-stress test and biophysical profile).

    Measured: Estimated gestational age (EGA) approximately 36 weeks

  4. Cmin of buprenorphine and metabolites in plasma

    A blood draw at the estimated time of minimum drug concentration ("trough") to evaluate trough-to-peak fluctuation for the conceptual model.

    Measured: Estimated gestational age (EGA) approximately 36 weeks

  5. Cmax of buprenorphine and metabolites in plasma

    A blood draw at the estimated time of maximum drug concentration ("peak") to evaluate trough-to-peak fluctuation for the conceptual model.

    Measured: Estimated gestational age (EGA) approximately 36 weeks

  6. Concentration of buprenorphine and metabolites in maternal plasma

    A blood draw around the time of delivery to evaluate the association between drug concentration and neonatal opioid withdrawal syndrome outcomes.

    Measured: Delivery

  7. Concentration of buprenorphine and metabolites in cord plasma

    Cord blood will be collected and used to estimate fetal exposure to buprenorphine.

    Measured: Delivery

Questions about this trial

What is this clinical trial studying?

An observational study of Opioid-Related Disorders and Drug Addiction, run by T. John Winhusen, PhD at 12 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 16 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cmin of buprenorphine and metabolites in plasma (time frame: 2 weeks post-randomization). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03911466, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Mar 2026.
