NCT01560507

Brief Summary

The purpose of this study is to ascertain: 1) the rate of smoking cessation obtained using an adaptive treatment algorithm developed in previous clinical trials, in order to calculate cost-effectiveness of the treatment; 2) the relationship between genotype and response to cigarette smoking cessation treatment.

Outcome Measures

Primary Outcomes (1)

  • Cost-effectiveness of the Adaptive Treatment Approach to Smoking Cessation

    Study was terminated early due to difficulties with enrollment. No outcome measures were assessed.

    End of study drug treatment period (11-12 weeks)

Secondary Outcomes (1)

  • Quit Success Genotype Score

    After 6 month Follow-Up

Study Arms (3)

varenicline (Chantix)

ACTIVE COMPARATOR

This group will consist of smokers who, based on smoking behavior, DO NOT respond favorably to pre-cessation Nicotine Replacement Therapy (NRT) assessed the day before the scheduled quit day. They will receive varenicline.

Drug: varenicline (Chantix)

nicotine patches

ACTIVE COMPARATOR

This group will consist of smokers who, based on smoking behavior, respond favorably to pre-cessation NRT (assessed the day before the scheduled quit day). They will continue to using only nicotine patches.

Drug: nicotine patches

bupropion (Zyban) and nicotine patches

ACTIVE COMPARATOR

This group will consist of smokers who, based on smoking behavior, DO NOT respond favorably to pre-cessation NRT (assessed the day before the scheduled quit day). They will receive bupropion with nicotine patches.

Drug: bupropion (Zyban)Drug: nicotine patches

Interventions

For the first 3 days after being switched from NRT (occurring at one week before the rescheduled quit date), smokers in this group will receive varenicline at a dose of 0.5 mg once per day followed by 0.5 mg twice a day for the remaining 4 days of that week. Subsequently, the dose will be 1 mg twice per day, and will remain at that dose for the remainder of the 12 weeks.

Also known as: Chantix, varenicline
varenicline (Chantix)

After being switched from NRT (occurring at one week before the rescheduled quit date), smokers in this group will receive 150mg of bupropion once daily and 21mg nicotine patch for first 3 days; 150mg of bupropion twice daily and 21mg nicotine patch for 7 weeks; 150mg of bupropion twice daily and 14mg nicotine patch for 2 weeks and 150mg of bupropion twice daily and 7mg nicotine patch for 2 weeks.

Also known as: Zyban, bupropion
bupropion (Zyban) and nicotine patches

21mg nicotine patch for first 11 weeks; 14mg nicotine patch for next 2 weeks; 7mg nicotine patch for final 2 weeks.
