This is a prospective, double-blind placebo-controlled randomized pilot trial of the preliminary safety and efficacy of bupropion SR in combination with behavioral counseling for smoking cessation during pregnancy.

Studienübersicht

Detaillierte Beschreibung

This is a prospective, double-blind placebo-controlled randomized pilot trial of the preliminary safety and efficacy of bupropion SR in combination with behavioral counseling for smoking cessation during pregnancy. A total of 150 pregnant smokers will receive medication (75) or placebo (75) for 12 weeks. Compassionate care/continuance of therapy will be available to pregnant subjects. Women who relapse to smoking postpartum will be offered an additional course of medication treatment. All subjects regardless of adherence with 12 week study drug administration period and smoking habits during pregnancy will be followed through the duration of their pregnancy, delivery, and 6-month postpartum period. Subject participation will begin between 13-30 wks of gestation and end 6 months postpartum. Participation will be ten (10) to thirteen(13) months in length.

Intervention / Behandlung
Aktiver Komparator: Bupropion SR + cessation counseling

Bupropion SR and smoking cessation counseling Subjects received Bupropion SR 150 mg tablet orally twice daily (BID) for 12 weeks. Subjects were instructed to begin using study medication (bupropion SR 150 mg orally for 3 days, then BID for 4 days) on study visit day 1, which was approximately 1 week prior to their quit date. Thereafter, they were continued to dose Bupropion SR 150 mg tablet orally BID for a total medication treatment of 12 full weeks.

Smoking cessation counseling included 35-minute counseling sessions at each of the first 2 visits and 10 minutes of smoking cessation counseling at subsequent visits, provided by the trained study nurse.

Placebo-Komparator: Placebo + cessation counseling

Placebo and smoking cessation counseling Subjects received matching Bupropion SR placebo tablet orally twice daily (BID) for 12 weeks. Subjects were instructed to begin using study medication (matched placebo tablets orally for 3 days, then BID for 4 days) on study visit day 1, which was approximately 1 week prior to their quit date. Thereafter, they were continued to dose matching Bupropion SR placebo tablet orally BID for a total medication treatment of 12 full weeks of therapy.

Zeitfenster
Change in Cigarette Craving and Total Nicotine Withdrawal Symptoms Between Groups During Medication Treatment
Zeitfenster: During treatment: Visits 2-6 (time period between 2nd and 12th week of therapy)
Cigarette craving and withdrawal symptoms were assessed by the Minnesota Nicotine Withdrawal Scale (MNWS). MNWS consists of 7 objectives (e.g., irritability, anxious, depressed mood, difficulty concentrating, increased appetite, insomnia, restless). Subjects were given a score on each item on a scale of 0 (not present) to 4 (severe). Summed (total) score excluding craving represent subject's symptoms of tobacco withdrawal, ranging from 0 to 28. We calculated a craving for tobacco score and a total score of withdrawal symptoms excluding craving. The higher score represent more sever craving and withdrawal.

Change in Cigarette Craving and Total Nicotine Withdrawal Symptoms Between Groups on the Quit Date
Zeitfenster: Quit date, visit 2 (one week after starting the 12-week course of therapy)
Cigarette craving and withdrawal symptoms were assessed by the Minnesota Nicotine Withdrawal Scale (MNWS). MNWS consists of 7 objectives (e.g., irritability, anxious, depressed mood, difficulty concentrating, increased appetite, insomnia, restless). Subjects were given a score on each item on a scale of 0 (not present) to 4 (severe). Summed (total) score excluding craving represent subject's symptoms of tobacco withdrawal, ranging from 0 to 28. We calculated a craving for tobacco score and a total score of withdrawal symptoms excluding craving. The higher score represent more sever craving and withdrawal.

Number of Participants With 7-day Point Prevalence Smoking Abstinence at the End of Medication Treatment (Visit 6)
Zeitfenster: Visit 6 (end of 12 weeks of medication therapy)
The accuracy of self-reported smoking abstinence during study visits was confirmed by an exhaled carbon monoxide (CO) levels and by urinary cotinine levels. 7-day point prevalence abstinence was defined as no cigarettes (not even a puff) in the last 7 days, levels of (CO) in exhaled air < 4 ppm, and concentrations of cotinine in urine < 50 ng/mL. At every visit, a research nurse monitored the smoking status of all subjects (amount of cigarettes per day, exhaled CO). Exhaled CO was measured using a Vitalograph carbon monoxide monitor (Lenexa, KS) according to the manufacturer's recommendations. A urine sample was collected at each visit and cotinine in urine was quantified using the validated liquid chromatography-mass spectrometry (LC/MS) method. We calculated the total number of abstinent subjects. The higher the number the better outcome.
Visit 6 (end of 12 weeks of medication therapy)
Number of Participants With 7-day Point Prevalence Smoking Abstinence at the End of Pregnancy (Visit 7)
Zeitfenster: End of pregnancy (visit 7) is a time period between 36.0-38.6 weeks gestation
The accuracy of self-reported smoking abstinence during study visits was confirmed by an exhaled carbon monoxide (CO) levels and by urinary cotinine levels. 7-day point prevalence abstinence was defined as no cigarettes (not even a puff) in the last 7 days, levels of (CO) in exhaled air < 4 ppm, and concentrations of cotinine in urine < 50 ng/mL.
