Brief Summary:
This is a single-center, open-label, concentration-ranging study to evaluate the nicotine PK profile and PD effects in healthy adult experienced users of closed tank/cartridge e-cigarettes using four different variants of P4M3 (nicotine concentration of 1.7%, 1.7% with 1.1% lactic acid [LA], 3% with 1.1% LA, and 4% with 2% LA) or their own e-cigarettes.

Condition or disease Intervention/treatment Phase
Vaping Nicotine Absorption Other: E-cigarette Other: P4M3-1.7% Other: P4M3-1.7%LA Other: P4M3-3%LA Other: P4M3-4%LA Not Applicable

Detailed Description:

The goal of the study is to evaluate the nicotine concentration profiles and derived PK parameters, subjective effects, behavioral parameters, including puffing topography parameters of P4M3 with four different variants of P4M3, in experienced e-cigarette users after a single-use experience with fixed puffing and after ad libitum use of P4M3.

Four variants of P4M3 will be evaluated together with subjects' own e-cigarettes to evaluate the relationship between the e-liquid composition (nicotine concentrations and presence of lactic acid) and the amount of nicotine absorbed, the speed of absorption, and the puffing topography.

  3. Time to peak plasma nicotine concentration [tpeak] [ Time Frame: From Day -1 (baseline) to Day 4 ]
    To measure the time to peak plasma nicotine concentration [tpeak] from 60 minutes of ad libitum use.

  4. Background-corrected trough plasma nicotine concentration [cCtrough] [ Time Frame: From Day -1 (baseline) to Day 4 ]
    To measure background-corrected trough plasma nicotine concentration [cCtrough] from 60 minutes of ad libitum use.

  5. Background-corrected average of plasma nicotine concentration [cCaverage] [ Time Frame: From Day -1 (baseline) to Day 4 ]
    To measure background-corrected average of plasma nicotine concentration between 0 to 1 hour [cCaverage] from 60 minutes of ad libitum use.


Secondary Outcome Measures :
  1. Total and background-corrected plasma nicotine concentration versus time profiles [ Time Frame: From Day -1 (baseline) to Day 4 ]
    To measure the total and background-corrected plasma nicotine concentration versus time profiles of the P4M3 variants and subjects' own e-cigarette from the fixed puffing regimen.

  2. Background-corrected maximum plasma concentration [cCmax] [ Time Frame: From Day -1 (baseline) to Day 4 ]
    To measure the background-corrected maximum plasma concentration [cCmax] of the P4M3 variants and subjects' own e-cigarette from the fixed puffing regimen.

  3. Time to the maximum concentration [tmax] [ Time Frame: From Day -1 (baseline) to Day 4 ]
    To measure the time to the maximum concentration [tmax] of the P4M3 variants and subjects' own e-cigarette from the fixed puffing regimen.

  4. Background-corrected area under the concentration-time curve [cAUC(0-4h)] [ Time Frame: From Day -1 (baseline) to Day 4 ]
    To measure the background-corrected area under the concentration-time curve, which is above the corrected baseline from the start of product use to 4 hours [cAUC(0-4h)], of the P4M3 variants and subjects' own e-cigarette from the fixed puffing regimen.

  5. Subjective effects of P4M3 use [ Time Frame: From Day -1 (baseline) to Day 4 ]
    Measured with an adapted version of the modified Cigarette Evaluation Questionnaire (adapted mCEQ) within 60 minutes after the ad libitum use session.

  6. Craving for an electronic cigarette [ Time Frame: From Day -1 (baseline) to Day 4 ]
    Measured on on a Visual Analogue Scale (VAS) of 0 (no craving) to 10 (strong craving), before and after the fixed puffing regimen and ad libitum use period.

  7. Sensory parameters [ Time Frame: From Day 1 to Day 4 ]
    Measured with a Sensory Questionnaire (SQ) within 60 minutes after each fixed puffing regimen and ad libitum use period.

  8. Human puffing topography (HPT) of the P4M3 variants and the subjects' own e-cigarette [ Time Frame: From Day -1 (baseline) to Day 4 ]
    Measure per-puff parameters and per-product use experience parameters of the P4M3 variants and the subjects' own e-cigarette from the fixed puffing regimen and the 60 minutes ad libitum use.

    AEs and SAEs will be collected through spontaneous reporting or by the use of consistent, open, non-directive questions from the investigational site collaborators.
