A randomized clinical trial of counseling and nicotine replacement therapy for treatment of African American non-daily smokers: Design, accrual, and baseline characteristics.
Contemporary Clinical Trials 2018 July
BACKGROUND: Non-daily smokers (NDS) who smoke on some but not all days are a growing subset of United States (US) tobacco users. Racial/ethnic minorities are more likely to be NDS. African American NDS have strikingly high levels of nicotine and carcinogen exposure, making treatment of this high risk group a priority.
METHODS: The current study is one of three ongoing federally-funded clinical trials of NDS and, to our knowledge the only RCT focused on racial/ethnic minority NDS. The design has been guided by input from Patient and Stakeholder Advisory Panels who helped develop the research questions, design the intervention, and select the outcomes. The objective is to compare the effectiveness of smoking cessation counseling alone (C) or smoking cessation counseling plus participant's choice of nicotine replacement therapy (NRT; C + NRT) for African American NDS. Two-hundred seventy-eight African American NDS will be randomized in a 2:1 fashion to C + NRT or C. All participants receive five sessions of smoking cessation counseling; those randomized to C + NRT receive their choice of nicotine gum, patch, and/or lozenge. Treatment in both groups lasts for 12 weeks. We hypothesize that C + NRT will be more effective than C on the primary outcome of biochemically-confirmed abstinence from smoking at week 12. Secondary aims will compare C + NRT and C on patient- and provider-desired outcomes including abstinence from smoking at week 26, change in biochemically-verified nicotine and carcinogen exposure, days abstinent, and treatment process measures (e.g., NRT use and side effects). Predictors of abstinence will also be explored.
DISCUSSION: Findings will illuminate effective treatment options for African American NDS and contribute to development of evidence-based guidelines for treating the 8.9 million US adult NDS for whom no guidelines currently exist.
TRIAL REGISTRATION NUMBER: ClinicalTrials.gov: NCT02244918.
