Study Details

Study Description

Brief Summary

Smoking during pregnancy adversely affects the health of the mother and her developing baby. Maternal smoking approximately doubles the risk of miscarriage, placental complications, preterm delivery, low birth weight and fetal and newborn death. The most common adverse effect of smoking during pregnancy is low birth weight, which sharply increases the risk of the newborn becoming ill or dying. In the US, maternal smoking is responsible for 30% of low birth weight babies, 10% of premature deliveries, and 5% of infant deaths. Fortunately, smoking cessation by pregnancy week 16, or as late as the third trimester, results in a near-normal weight infant at birth. Even reductions in smoking increase birth weight.

Despite the known risks, the majority of women who are smoking at the time of their first prenatal visit continue to smoke. Bupropion is approved by the US Food and Drug Administration (FDA) for smoking cessation in people who are not pregnant, but there are no carefully controlled studies on the use of Bupropion to help pregnant women quit smoking. Bupropion is also FDA approved to treat depression, and some pregnant women have taken it for that purpose, even though it has not been formally tested. The investigators propose to conduct a randomized, parallel-group, double-blinded, placebo-controlled, 10 week trial of Bupropion in 360 pregnant women who smoke daily and wish to quit smoking.

The study has three primary hypotheses. First, the investigators hypothesize that Bupropion treated subjects will decrease the frequency of smoking more than placebo-treated subjects. Second the investigators hypothesize that Bupropion treated subjects will have greater positive pregnancy and child health outcomes than placebo-treated subjects. Third the investigators hypothesize that Bupropion treated subjects will have decreased frequency of depressive symptoms and cigarette craving than placebo-treated subjects. These finding will provide information on the safety and efficacy of bupropion treat for smoking cessation in pregnant women.

Smoking; Nicotine Dependence	Drug: Bupropion	Phase 2

Detailed Description

1. General Design: This is a phase II, prospective, placebo-controlled randomized controlled trial of the efficacy and safety of bupropion in combination with behavioral counseling for smoking cessation during pregnancy. Pregnant smokers (N=360) will receive bupropion or placebo treatment for 10 weeks, under strict double-blind conditions, with 3 post-treatment follow-up sessions: 2 and 6 weeks postpartum (with counseling to prevent relapse or encourage a repeat quit attempt) and monitoring of the persistence of treatment effects at 24 weeks post-quit date.

2. Recruitment: We will distribute IRB (Institutional Review Board)-approved brochures and posters to recruit pregnant women who smoke and wish to quit smoking through participation in the trial. At Penn Medicine sites, we will access the hospitals' EPIC computer programs to identify pregnant smokers receiving prenatal care and, working with their obstetrician, invite them to consider study participation. We will conduct a brief screening interview over the phone or in-person at the participant's obstetrics clinic to assess study eligibility criteria. Prospective participants who appear to meet eligibility criteria for the study will be scheduled for an in-person Informed Consent and Screening visit.

3. Screening Visit: Participants will read and sign the informed consent form, after all of their questions have been answered. Participants will then be asked to provide the researchers with information to determine whether they are eligible to participate in the study. On this visit, participants will be interviewed for about an hour. This interview will include questions about medical and pregnancy history, and any mood or other symptoms and determine the baby's date of delivery. We will also ask about any past or current use of alcohol, drugs, and cigarettes.

D: Baseline Visit: This in-person visit will be completed within 30 days of the screening visit and will last approximately 90 minutes. At the visit, we will measure heart rate and complete questionnaires by telephone and in person. We will take a blood sample (3 tubes, enough to fill 1.5 tablespoons) to be used to conduct genetic testing and to measure the body's ability to break down nicotine, which is contained in cigarettes.

At this visit participants will receive the first of six counseling sessions in the study. This first, "pre-quit" counseling session will last 30 minutes and will help to prepare them to quit smoking. They will be given study medication at this visit and will be instructed to begin taking it the following morning. They will be asked to identify a quit date within a week of beginning the study medication. They will start the study medication by taking one capsule (150 mg/day or placebo, a harmless, inactive substance) each morning for the first 3 days and then one capsule each morning and each evening (150 mg twice daily) for the remainder of the 10-week study treatment period. At this visit, and at every visit while taking the study medication, we will record any side effects that may have been experienced from the study medication. We will also ask participants to return all study medication that they have not taken and the study medication bottle.

The day after the Baseline Visit, the participants will begin to receive two daily text messages. The first message of the day (in the morning) will provide information on the expected development based on the baby's age, accompanied by a reminder to take the study medication. The second message of the day (in the evening) will ask the participants whether they took all of their study medication that day. They'll be asked to text back indicating that they received the message (in the morning) and whether they took the medication that day (in the evening). We will ask them which times they would like to receive the text messages each day. Although the information that they provide will help us to keep track of their participation, the inbox for our texting center is not monitored, so we will direct them to call our study staff to speak with them directly, rather than texting them if they have any study-related questions.

Visit C: Quit Date Visit: The scheduled quit date visit will occur approximately one week after the baseline visit and will last approximately 45 minutes. During this visit, we will measure the participants' heart rate and ask them to blow into an instrument that measures a chemical (carbon monoxide) that is in tobacco smoke. The study nurse will collect any medication not taken and the study medication bottle. The participants will receive a four-week supply of study medication and a study nurse will ask them about any study medication side effects that they may have experienced since starting the study. They will also be asked to complete some questionnaires and will receive 20 minutes of "quit-day" counseling, which will help them to identify things that could cause them to return to smoking and to develop a plan to avoid tempting situations.

Visit D: Week 3: This visit will occur by telephone and will last approximately 25 minutes, during which time the participants will be asked to complete questionnaires over the telephone. They will be asked about their cigarette use since the last visit and any medication side effects they may have experienced. They will also receive 10 minutes of counseling by phone to help them avoid smoking or, if they need to, set another quit date to try again to quit smoking.

Visit E: Week 5: This in-person visit will last approximately 30 minutes. The participants will be asked to complete some questionnaires and be interviewed about their cigarette use since the last visit. We will measure their heart rate and they will be asked to blow into an instrument that measures a chemical (carbon monoxide) that is in tobacco smoke. They will be asked to provide a blood sample (2 tubes, enough to fill 1 tablespoon) to be used to measure the concentration of study medication in the blood. The study nurse will collect any medication that the participants have left as well as the study medication bottle. They will receive a five-week supply of study medication and a study nurse will ask them about any study medication side effects that they may have experienced since starting the study. They will also receive 10 minutes of counseling to help they avoid smoking or, if needed, set another quit date to try quitting again.

Visit F: Week 7: This telephone visit will last approximately 15 minutes. The participants will be asked to complete some questionnaires. They will also be asked about their cigarette use since the last visit and any medication side effects they may have experienced.

Visit G: Endpoint visit: This in-person visit will last approximately 25 minutes. The participants will be asked to complete questionnaires and about their cigarette use since the last visit. During the visit we will measure their heart rate and they will be asked to blow into an instrument that measures a chemical (carbon monoxide) that is in tobacco smoke. The study nurse will collect any medication that they had not taken and the study medication bottle. The study nurse will ask them about any study medication side effects that they may have experienced since starting the study.

Visit H: Week 24 after the Quit Date: About six months after the participants started treatment, they will be contacted by telephone. During this phone call, a research technician will complete several questionnaires with them, similar to those they completed previously. Some participants will be asked to come back to the center following this interview to provide carbon monoxide breath samples as they did previously. Approximately two weeks prior to the phone call we may send a reminder letter that the phone visit is coming up.

Visits I and J: 2 and 6 weeks after delivery: The last two sessions will be held by telephone after the birth of the baby. The participants will be asked to complete several questionnaires, similar to those completed previously. They will also receive 10 minutes of counseling over the phone.

Outcome Measures

Primary Outcome Measures

1. Number of Participants With Cessation Success at Week 10 After Target Quit Date [10 weeks]

   Participants will be considered to be abstinent if they self-report abstinence (not even a puff of a cigarette) for >7 days prior to the assessment after 10 weeks of treatment post-To Quit Day and have a CO <8 ppm at that time. As per convention, participants are assumed to be smoking if they self-report to be smoking at the time point, cannot be reached to provide data at the time point, fail to provide a breath sample at the time point, or provide a breath sample at the time point that has a CO concentration >8 ppm.

2. Number Moderate or Severe Side Effects [10 week treatment phase]

   For adverse effects, our primary outcome will be the frequency of moderate or severe side effects from a checklist of bupropion-related side effects (derived from completed bupropion studies), as well as those elicited with open-ended questions, through regular obstetrics visits, and assessments triggered by any pregnancy-related complication. Adverse effects will be systematically assessed by study personnel at 5 time points over the course of the 10-week study and can trigger dose reductions or suspension of medication.

3. Birth Outcomes for Gestational Age [Postpartum]

   Birth outcomes obtained from labor and delivery records gestational age, measured in weeks.

4. Birth Weight Outcomes [Postpartum]

   Birth weight outcomes were obtained from labor and delivery clinical records. Birth weight is measure in grams.

5. Birth Outcomes, Size (Percentile) for Gestational Age. [Postpartum]

   Birth outcomes obtained from labor and delivery records infant size for gestational age, whether small for gestational age (i.e., <10th percentile birth weight for gestational age as determined by the Alexander curve).

6. Birth Outcomes Head Circumference. [Postpartum]

   Birth outcomes obtained from labor and delivery records head circumference measured in centimeters.

7. Birth Outcomes 5-minute Appearance, Pulse, Grimace, Activity, and Respiration Score [postpartum]

   Birth outcomes obtained from labor and delivery records 5-minute Appearance, Pulse, Grimace, Activity, and Respiration score (APGAR). The Apgar score has a range from 0 to 10. A 5-minute Apgar score of 7-10 as reassuring, a score of 4-6 as moderately abnormal, and a score of 0-3 as low in the term infant and late-preterm infant 6.
