Primary Outcome Measures:
  • Nicotine Cmax [ Time Frame: Single use (1 day) ] [ Designated as safety issue: No ]
    Maximum plasma concentration (Cmax)

  • Nicotine AUC [ Time Frame: Single use (1 day) ] [ Designated as safety issue: No ]
    Nicotine plasma concentration, area under the curve (AUCt)


Secondary Outcome Measures:
  • Nicotine concentrations [ Time Frame: Single use (1 day); multiple use (1 day) ] [ Designated as safety issue: No ]
    Time course of plasma nicotine concentration

  • Questionnaire of smoking urges (brief version) (QSU-brief) [ Time Frame: single use (1 day); multiple use (1 day) ] [ Designated as safety issue: No ]
    QSU-brief measuring subjective effects of smoking

  • Safety monitoring [ Time Frame: 7 days + 7 days follow-up ] [ Designated as safety issue: Yes ]
    Monitoring of adverse events, based on clinical and laboratory evaluation

  • Nicotine tmax [ Time Frame: Single use (1 day) ] [ Designated as safety issue: No ]
    Time to maximal nicotine concentration in plasma

  • Cough Visual Analog Scale [ Time Frame: 7 days ] [ Designated as safety issue: No ]
    Visual Analog Scale on cough

  • Modified Cigarette Evaluation Questionnaire (MCEQ) [ Time Frame: single use (1 day); multiple use (1 day) ] [ Designated as safety issue: No ]
    MCEQ measuring effects of smoking


Enrollment: 33
Study Start Date: May 2012
Study Completion Date: December 2012
Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: smoking conventional cigarettes (CC)
After a 1-day nicotine deprivation, subjects are smoking one single cigarette (usual own brand) on one day and then smoking ad libitum on the subsequent day
 Other: Conventional cigarettes (CC)
Subjects are randomized in a 1:1 fashion to be assigned to one of the 2 sequences, either A) CC and then THS 2.1, or B) THS 2.1 and then CC.
Other: THS 2.1
Subjects are randomized in a 1:1 fashion to be assigned in one of the sequences, either A) CC and then THS 2.1, or B) THS 2.1 and then CC
Experimental: using the Tobacco Heating System 2.1 (THS 2.1)
After a 1-day nicotine deprivation, subjects are puffing one single tobacco stick using the THS 2.1 on one day and then puffing ad libitum on the subsequent day
 Other: Conventional cigarettes (CC)
Subjects are randomized in a 1:1 fashion to be assigned to one of the 2 sequences, either A) CC and then THS 2.1, or B) THS 2.1 and then CC.
Other: THS 2.1
Subjects are randomized in a 1:1 fashion to be assigned in one of the sequences, either A) CC and then THS 2.1, or B) THS 2.1 and then CC

Detailed Description:

This 2-period 2-sequence cross-over clinical study intends to explore the profile of nicotine uptake (rate and extent of nicotine absorbed and associated variability) in healthy smokers switching from (CC) to THS 2.1 (single or ad libitum use) compared to smokers continuing to use CC, as a comparator. This study will serve to optimize blood sampling schedules and sample size estimation for further studies. This study will also provide preliminary information on the relationship between nicotine absorption and urge to smoke/withdrawal symptoms when using THS 2.1 as compared to CC, as well as the safety profile, which is related to the use of THS 2.1.

After screening, enrolled subjects will be admitted to the clinic for 8 days. This study duration includes 2 consecutive periods. Each period consists of 1 day for single use of the product preceded by a 24-hour nicotine deprivation, and 1 day for ad libitum product use. After leaving the clinic, the subjects will be followed up for safety over a period of 7 days.

This clinical study will be conducted in compliance with International Conference on Harmonisation of technical requirements for registration of pharmaceuticals for human use (ICH Good Clinical Practice), the Declaration of Helsinki as amended in 2008, and the applicable regulatory requirements.
