Scientific titleNicotine gum treatment before smoking cessation, a randomised trial
Study acronymEtude nicotine
Study objectivesNicotine replacement therapy (NRT) taken for one month before and two months after smoking cessation will be more effective than usual care i.e. NRT for two months after the quit date.

Intervention typeDrug
Pharmaceutical study type(s)
PhaseNot Specified
Drug / device / biological / vaccine name(s)Nircotine replacement therapy (NRT)
Primary outcome measure1. Smoking status at the target quit date, and 2, 12 and 60 months thereafter. We will use the criterion recommended by the U.S. Food and Drugs Administration (FDA) to assess outcome in smoking cessation studies: not having smoked even one puff of tobacco during the previous 4 weeks, and the criterion recommended in a recent guideline: not having smoked even one puff of tobacco in the previous 7 days. At 12 months only, smoking abstinence will be verified by saliva cotinine and, if positive, by expired carbon monoxide.
2. Tobacco withdrawal symptoms at the target quit date and 2 months thereafter
3. Utilisation of nicotine gums at the target quit date and 2 months thereafter (number of gums per day and duration of use)
Secondary outcome measuresAt 12 months, we will use as secondary outcome the recently recommended criterion of 6 months of continuous abstinence.
Other outcomes:
1. Quit attempts (number and duration)
2. Motivation to quit smoking
3. Confidence in ability to quit smoking, self-efficacy
4. Cigarette consumption
5. Level of dependence on cigarettes, assessed with the CDS-12 test
6. Side-effects of NRT
7. Attitudes towards NRT, in particular perception that NRT is dangerous
