NCT02796391

Brief Summary

STUDY 1: INTERVENTION DEVELOPMENT The purpose of this study is to determine the best way to help people stop smoking by using very low nicotine content (VLNC) cigarettes. This developmental pilot study (n=20) will determine the feasibility of the treatment approach and methodology using a targeted intervention, and lead to refinements for a subsequent randomized controlled trial (RCT). STUDY 2: RANDOMIZED CONTROLLED TRIAL The purpose of this study is to see if a targeted intervention will help people to stop or reduce smoking better than a standard intervention using very low nicotine content (VLNC) cigarettes, and to determine the optimal nicotine tapering schedule (gradual vs. immediate) during a 5-week pre-quit period. About 208 participants will take part in this phase of the study at Moffitt Cancer Center.

Outcome Measures

Primary Outcomes (3)

  • Study 1 - Rate of Participant Completion of Pilot

    Pilot: Complete formative research based on 15 participants to prepare for Study 2.

    Up to 2 Weeks

  • Study 2 - Participant Abstinence Success at 2 Months

    Participants reporting 7-day point prevalence abstinence at 2 months RCT: The purpose of Study 2 is to test effects of the targeted intervention developed in Study 1 on smoking cessation. Comparison of abstinence success per treatment arm, utilizing 7-day point prevalence abstinence at each follow-up assessment.

    At 2 Months

  • Study 2 - Participant Abstinence Success at 6 Months

    Participants reporting 7-day point prevalence abstinence at 6 months RCT: The purpose of Study 2 is to test effects of the targeted intervention developed in Study 1 on smoking cessation. Comparison of abstinence success per treatment arm, utilizing 7-day point prevalence abstinence at each follow-up assessment.

    At 6 Months

Study Arms (6)

Study 1: Immediate Reduction

EXPERIMENTAL

Participants will receive cigarettes with the lowest nicotine dose (.03 mb nicotine yield). They will receive a targeted intervention workbook ("Count down: Preparing to Quit Smoking with Low-Nicotine Cigarettes") and will be provided with one-on-one counseling.

Drug: Very Low Nicotine Content (VLNC) CigarettesBehavioral: One on One Counseling

Study 1: Gradual Reduction

EXPERIMENTAL

Participants will receive VLNC (very low nicotine cigarettes) containing nicotine yields of .7 mg for week 1, .26 mg for week 2, .12 for week 3, and .03 for week 4.They will receive a targeted intervention workbook ("Count down: Preparing to Quit Smoking with Low-Nicotine Cigarettes") and will be provided with one-on-one counseling.

Interventions

Eligible participants will receive a 1-week supply (based on typical # cigarettes/day x 1.5) of normal nicotine content (NNC) (.8 mg nicotine yield) study cigarettes to smoke exclusively during one baseline week. Study 1: Participants (n=20) will then be randomly selected to receive either the lowest nicotine dose of VLNC cigarettes, or gradual decreasing nicotine VLNC cigarettes, ten participants per each group, over the next four weeks. Study 2: Participants (n=208) will be randomly assigned to 1 of 4 Study 2 Reduction Arms, 52 participants per arm.
