NCT00330187

Brief Summary

In the current proposal, we intend to study the efficacy of bupropion SR with or without combined contingency management (CM) among adolescent cigarette smokers. The proposed study will test not only medication (bupropion SR), but also combination of medication and CM in potentially improving smoking cessation outcomes AND retention of adolescent smokers in the study. Hypothesis to be tested: Bupropion SR treatment will increase abstinence from cigarette smoking (as measured by urine cotinine and continuous abstinence) in adolescent smokers as compared to treatment with placebo only. Hypothesis to be tested: Adolescent smokers treated with combined bupropion SR + contingency management (CM) treatment will have increased retention and increased abstinence rates when compared to bupropion SR alone or CM + placebo treated groups (as measured by decreased drop-out of participants, urine cotinine and continuous abstinence). Hypothesis to be tested: CM will increase the abstinence from cigarette smoking (as measured by urine cotinine and continuous abstinence) in adolescent smokers as compared to treatment with placebo only.

Outcome Measures

Primary Outcomes (1)

  • Biologically-verified 7-day Point Prevalence Smoking Abstinence

    Self-reported abstinence for the past 7 days, confirmed by urine cotinine ≤100 ng/mL

    End of treatment (week 6)

Study Arms (4)

Bupropion SR + Contingency Management

EXPERIMENTAL

Bupropion SR capsules, with goal dose of 300 mg/day, for 6 weeks of treatment. Contingency Management, with escalating rewards for abstinence (and re-sets for non-abstinence) at twice-weekly visits.

Drug: Bupropion SRBehavioral: Contingency Management

Placebo + Contingency Management

ACTIVE COMPARATOR

Placebo capsules, matched in appearance to Bupropion SR capsules, for 6 weeks of treatment. Contingency Management, with escalating rewards for abstinence (and re-sets for non-abstinence) at twice-weekly visits.

Behavioral: Contingency ManagementOther: Placebo

Bupropion SR + No Contingency Management

ACTIVE COMPARATOR

Bupropion SR capsules, with goal dose of 300 mg/day, for 6 weeks of treatment. Contingency Management is not provided in this arm.

Drug: Bupropion SR

Placebo + No Contingency Management

PLACEBO COMPARATOR

Placebo capsules, matched in appearance to Bupropion SR capsules, for 6 weeks of treatment. Contingency Management is not provided in this arm.

Other: Placebo

Interventions

Eligibility Criteria

Age12 Years - 21 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Regular cigarette smokers smoking at least 5 cigarettes per day as derived by Time-Line Follow-Back method (Sobell et al., 1988). Average number of cigarettes per day (over past 30 days) will be used. Five cigarettes per day may seem low, but based on previous studies, adolescents tend to smoke fewer cigarettes per day as compared to adults.
  • Baseline urine cotinine level greater than 100 ng/ml.
  • Age range of 12 - 21
  • If under 18 yr. of age, parent(s) or guardian(s) able to participate in informed consent and initial assessment, or the participant must provide evidence of emancipated status.
  • For post menarchal female participants: agree to use birth control to avoid pregnancy.

You may not qualify if:

  • Active substance abuse/dependence (other than nicotine) within 2 weeks prior to participating in the study
  • Lifetime bipolar affective disorder (BPAD), psychosis, eating disorders. Bupropion may have adverse consequence on participants with these psychiatric diagnoses.
  • Pregnancy or lactation. The safety of bupropion in pregnancy and during lactation is not well studied.
  • History of seizure disorder or predisposition to seizures (e.g., history of significant head trauma, currently taking medications that lower seizure threshold), since bupropion can lower seizure threshold.
  • History of severe renal, hepatic, neurological, or chronic pulmonary disease. This criterion was chosen due to the hepatic metabolism of bupropion.
  • Unstable medical problems
  • Allergy to bupropion
  • Current treatment with any other medication containing bupropion
  • Current treatment with any monoamine oxidase (MAO) inhibitors currently or within 2 weeks of starting the study since there may be serious and severe medical interactions between MAO inhibitors and bupropion SR.
  • Current treatment with nicotine replacement therapy (NRT)
  • History of intolerance or non-response to bupropion SR.
  • Current (past month) suicide ideation
  • Suicide attempt (past year)
