E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy after a 3 months treatment by simvastatin versus placebo as an aid to quit smoking. The efficacy is estimated according the tobacco status: no reduction, reduction of 50% or more, abstinence. |
|
E.2.2 | Secondary objectives of the trial |
- To evaluate smoking abstinence rate. A participant is considered abstinent if he/she reports continuous abstinence from smoking confirmed by expired air carbon monoxide ≤8ppm and urinary cotinine concentration ≤10ng/mL during the last month of the 3 months treatment period.
- To evaluate the decrease in cigarette consumption over the 3-month period of treatment with simvastatin versus placebo
- To evaluate the duration of the abstinence from tobacco smoking over the 3-month period
- To evaluate changes in tobacco smoking behavior (craving)
