Buprenorphine for Opioid Addiction during Pregnancy
(MOMs-CMA Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests two types of buprenorphine, a medication for opioid addiction, to assess their effects on mothers and their babies during pregnancy. The main goal is to understand how different forms of the medication might influence the baby's heart rate, the mother's medication use, and infant development after birth. Participants will either take buprenorphine as a daily tablet or receive it as a weekly injection. Only those already part of the main MOMs trial can join this sub-study. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to important research that could lead to new treatment options for opioid addiction during pregnancy.
Do I need to stop my current medications for this trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that buprenorphine is a safe treatment for opioid addiction during pregnancy. Studies indicate that both the injection and sublingual (under-the-tongue) forms of buprenorphine do not increase risks for pregnant women or their babies. Buprenorphine is recommended for treating opioid use disorder (OUD) in pregnancy and has been linked to healthier babies with higher birth weights compared to those whose mothers did not receive treatment.
The sublingual form, often combined with naloxone, is considered safe and has been successfully used to treat opioid dependence in pregnant women. The injection form is also well-tolerated, with data showing no increased risk during pregnancy.
Overall, both the injection and sublingual forms of buprenorphine are trusted treatments for pregnant women with OUD, helping to improve health outcomes for both mothers and their babies.12345Why are researchers excited about this trial's treatments?
Researchers are excited about these treatments for opioid addiction during pregnancy because they offer new, flexible dosing options that might better meet individual needs. The Buprenorphine Injection (BUP-XR) is particularly notable because it is administered weekly or monthly, providing a long-acting option that could improve convenience and compliance compared to daily dosing. The Buprenorphine Sublingual Product (BUP-SL), on the other hand, offers flexibility in dosing, allowing adjustments based on cravings and withdrawal symptoms, which could enhance personalized care. These features could potentially offer more effective management of opioid addiction during pregnancy and postpartum periods, addressing both medical and lifestyle needs of new mothers.
What evidence suggests that this trial's treatments could be effective for opioid addiction during pregnancy?
Research has shown that buprenorphine effectively treats opioid use disorder during pregnancy. Studies indicate that buprenorphine helps pregnant women reduce opioid use and cravings. It can also lead to better outcomes for newborns, such as less severe symptoms of neonatal opioid withdrawal syndrome (NOWS). In this trial, participants may receive the under-the-tongue form of buprenorphine (BUP-SL), which is convenient and tends to reduce NOWS more than methadone. Alternatively, participants may receive the monthly injection form (BUP-XR), which has shown promise, with clinical cases demonstrating positive results for babies when pregnant women receive this treatment. Both forms of buprenorphine target the same brain receptors to manage opioid dependence effectively.13678

Are You a Good Fit for This Trial?
This trial is for expectant mothers who are already participating in the MOMs trial and have opioid use disorder. It aims to understand how different forms of buprenorphine affect both mother and infant outcomes, including withdrawal symptoms in newborns.Inclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Treatment
Participants receive either daily sublingual buprenorphine or weekly subcutaneous buprenorphine injection during pregnancy and postpartum
Follow-up
Participants are monitored for safety and effectiveness after treatment, including assessments of fetal heart rate variability and buprenorphine concentration in plasma
What Are the Treatments Tested in This Trial?
Interventions
- Buprenorphine Injection
- Buprenorphine Sublingual Product
Trial Overview
The study compares extended-release buprenorphine injections (BUP-XR) with sublingual products (BUP-SL), focusing on their effects on blood levels, fetal behavior, maternal adherence to medication, illicit opioid use, and infant development.
How Is the Trial Designed?

Experimental Treatment
Active Control
Weekly 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.).
Daily 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.).
