Tailored Smoking Cessation Treatment for LIVE FOR LIFE® Participants (LiveForLife2)
5. december 2014 opdateret af: Duke University
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.

Detaljeret beskrivelse
Previous research has shown that the initial response to nicotine patch treatment can be used to decide whether the patch alone is likely to help smokers to quit or whether alternative prescription medications may be needed to achieve smoking abstinence.
This study applies the knowledge gained from this previous research to adapt the smoking cessation treatment provided to participants, based on their degree of smoking reduction during the first four weeks of nicotine patch treatment.
By demonstrating effectiveness of this algorithm, this study may lead to further dissemination of the adaptive treatment strategy to other health care settings.
Additionally, by gathering further information relating genomic markers to outcome, the foundation will be laid for potential practical application of this index in other settings.

Deltagergruppe / Arm |
Intervention / Behandling |
|---|---|
|
Aktiv komparator: varenicline (Chantix)
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.
|
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.

Aktiv komparator: nicotine patches
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.
|
21mg nicotine patch for first 11 weeks; 14mg nicotine patch for next 2 weeks; 7mg nicotine patch for final 2 weeks.
|
|
Aktiv komparator: bupropion (Zyban) and nicotine patches
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.
|
21mg nicotine patch for first 11 weeks; 14mg nicotine patch for next 2 weeks; 7mg nicotine patch for final 2 weeks.
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.
