Brief Summary

The purpose of this study is to assess the amount of nicotine that is absorbed into the blood stream following the use of a new Electronic Cigarette device called the CN electronic cigarette. The amount of nicotine delivered via the CN electronic cigarette will be compared to the amount of nicotine delivered from smoking a regular cigarette and from using the Nicorette® Inhalator. Electronic cigarettes aim to mimic the experience of cigarette smoking, by delivering nicotine rapidly. Unlike cigarettes however, they do not contain all of the many harmful combustion products contained in tobacco smoke. Electronic cigarettes are readily available in many markets, and may contain significant quantities of nicotine. However, they are not regulated as medicines, and their manufacturers can make no medicinal claims about them. Such products are unregulated, having not been subjected to regulatory review by either the Medicines and Healthcare Products Regulatory Agency (MHRA) or any Notified Body. It is the intention of CN Creative (makers of the CN electronic cigarette) to submit an application to the MHRA for the CN Electronic Cigarette, in order to make a high quality, regulated product available. Males aged 18-65, who smoke and who have no intention of stopping smoking during the trial are eligible to take part in this study. The study consist of a screening visit, a treatment period with 5 overnight stays with nicotine treatment on days 1, 2, 3 and 4 with a post study visit on day 5.

Outcome Measures

Primary Outcomes (1)

• Cmax: The peak serum concentration of nicotine.

  PK samples taken after 4th administration immediately after dosing and 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 30, 60 minutes, and 2, 4, 6, 8, 12 and 20 hours afterwards. The pre-dose blood sample drawn on days 2, 3 and 4 will also serve as the 20 hour sample

  0 to 20h, PK parameters calculated after 4th Administration

• Regular moderate cigarette smokers (approximately 10 to 20 cigarettes per day for at least 5 years) who are not intending to make a quit attempt during the study.
• No obvious symptoms of ill health as determined during the pre-study medical examination (to be performed within 4 weeks of the first dose).
• Subject with no clinically significant abnormalities in 12-lead electrocardiogram (ECG), including normal resting ECG with QTcB interval of less than 440 ms determined within 4 weeks of the first dose.
• No clinically significant abnormalities in blood pressure values (the differences between supine and standing BP are less than 20 mmHg) with no symptomatic evidence of postural hypotension.
• Subject with no clinically significant abnormal serum biochemistry, haematology and urine examination values within 4 weeks of the first dose.
• Subject with a negative urinary drugs of abuse screen (excluding nicotine), determined within 4 weeks of the first dose (N.B. a positive alcohol result may be repeated at the discretion of the Investigator).
• Subject with negative HIV and Hepatitis B and C results.
• To be re-confirmed at Day 0:
• Subject with a negative urinary drugs of abuse screen (including alcohol) prior to dosing

You may not qualify if:

• To be confirmed at Screening Visit:
• Evidence of renal, hepatic, central nervous system, respiratory (including COPD), cardiovascular or metabolic dysfunction.
• Known allergy to any ingredients of the study medication.
• A history of or current drug or alcohol abuse.
• Inability to communicate well with the Investigator/study staff (i.e., language problem, poor mental development or impaired cerebral function).
• Participation in a New Chemical Entity clinical study within the previous 4 months or a marketed drug clinical study within the previous 3 months (N.B. washout period between trials defined as the period of time elapsed between the last dose of the previous study and the first dose of the next study..
• Donation of 450ml or more blood within the previous 3 months.
• Any other clinically significant medical history, in theInvestigator's opinion, including conditions which might affect drug absorption, metabolism or excretion.
• Unlikely to comply with trial visit schedule or with trial medication dosing requirements.
• Severe intercurrent illness which, in the opinion of the Investigator, may put the subject at risk when participating in the trial or may influence the results of the trial or affect the subjects' ability to take part in the trial.
• Excessive intake of alcohol, defined as a regular maximum weekly intake of greater than 28 units for men (1 unit equals half a pint of beer, 1 small glass of wine or 1 x 25 mL measure of spirits) within the last 6 months.
• Treatment with smoking cessation medications (bupropion, Champix, any NRT) within 8 weeks of the planned first nicotine dosing occasion.
• Treatment with prescription medications within 21 days or over-the-counter medication within 72 hours of the planned first nicotine dosing occasion.
• Clinical judgement by the Investigator that the subject should not participate in the study for any other reason.
• To be re- confirmed at Day 0:
