E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the effect of a single dose of EVT 302 on craving and withdrawal in smokers after short-term deprivation of cigarettes compared with placebo. |
|
E.2.2 | Secondary objectives of the trial |
• To assess the influence of a combination of EVT 302 with nicotine replacement therapy (NRT) versus the effect of EVT 302 alone and of NRT alone on craving and withdrawal in smokers • To assess the influence of EVT 302 alone and EVT 302 in combination with NRT, compared with NRT alone and placebo on cognition and reaction time • To assess the influence of EVT 302 alone, compared with placebo on mood and emotion • To assess the pharmacodynamic effect of EVT 302 on monoamine oxidase (MAO)-B platelet inhibition • To assess plasma concentrations of EVT 302 before and at the end of the smoking cessation period • To assess biomarkers for cigarette consumption • To assess the safety and tolerability of EVT 302 alone or in combination with NRT in smokers Hierarchy of testing for differences: Primary: EVT 302 versus Placebo Secondary: EVT 302 versus EVT 302 plus NRT EVT 302 versus NRT NRT versus Placebo |

Smoking of ≥17 and ≤34 cigarettes (i.e. between 1 and 2 packs) per day for the past year and have not tried to quit smoking in the 3 months prior to screening 8. Subjects should smoke their preferred cigarette brand during the study and must not change it during the entire study participation 9. Subjects are willing and, in the Investigator’s opinion, able to quit for about 12 hours in each of three subsequent study periods 10. Subjects are expected to experience craving symptoms after smoking cessation as known from previous attempts to quit smoking 11. Breath CO at least between 15 ppm and 20 ppm and cotinine in saliva at least 250 ng/mL at screening 12. Liver function test (LFT) results (Alanine aminotransferase [ALT], Aspartate aminotransferase [AST], Alkaline phosphatase [ALP], total bilirubin and Gammaglutamyl transferase [GGT]) not above 1.5 times the upper normal limit (UNL) at screening visit and at re-assessment during the study. 13. Have voluntarily provided informed consent and signed an informed consent form |

E.4 | Principal exclusion criteria |
1. Participation in another clinical study with an investigational medicinal product (IMP) within the 60 days before screening 2. Inability to understand the protocol requirements, instructions and study-related restrictions, the nature, scope, and possible consequences of the study 3. Unlikely to comply with the protocol requirements, instructions and study-related restrictions; e.g., uncooperative attitude, inability to return for follow-up visits, and improbability of completing the study 4. Evidence of active significant psychiatric or neurological disease or dependency other than cigarettes 5. Are known to have or are a carrier of the hepatitis B surface antigen (HBsAg), hepatitis C virus (HCV) antibody, has a positive result to the human immunodeficiency virus-1 and/or 2 (HIV-1 and/or HIV-2) antibodies 6. Subject is expected to be able to cease smoking easily for days without experiencing craving and smoking urges 7. Known hypersensitivity to MAO inhibitors or any substance that is contained in the study formulations 8. Known allergy to plasters or NRT patches 9. Previous participation in another study with EVT 302 10. Are currently receiving treatment for smoking cessation 11. Are currently using tobacco products other than cigarettes (e.g. pipes, cigars, snuff or chewing tobacco) 12. Require treatment with any medication 13. Blood or plasma donation of more than 500 mL in the 3 months before allocation or of 50 mL in the 2 weeks before the first dosing 14. Subject with a clinically relevant abnormal 12-lead ECG recording or QTcB/F >430 ms 15. Use of a prescription medicine during within 14 days or 5 half-lives, whichever is the longer, of the start of dosing, or use of an over-the-counter medication during the 7 days before the study, including herbal remedies, but excluding paracetamol and vitamin supplements (provided intake does not exceed the daily recommended allowance) 16. Subjects must not be planning to father a child or donate sperm, during the study and 3 months after the end of the study. Acceptable methods of contraception comprise barrier contraception and a medically accepted contraceptive method for the female partner (intra-uterine device with spermicide, hormonal contraceptive since at least 2 month) 17. Subject is the Investigator or any sub-investigator, research assistant, pharmacist, study coordinator, other staff or relative thereof directly involved in the conduct of the study 18.

Creatinine clearance (CLR) calculated according to the formula by Modification of Diet in Renal Disease (MDRD) of <80 mL/min and that in the opinion of the Investigator indicates renal impairment CLR will be calculated from serum creatinine values at Screening (Scr), using the following formula: Ccr = 170 x Scr-0.999 x age-0.176 x SUN-0.170 x Alb+0.318 age [years], Scr = serum creatinine, SUN = serum urea nitrogen, Alb = serum albumin. |
