    Evaluation of the diagnostic accuracy of a candidate biomarker to detect use of conventional cigarettes in users of tobacco products that do not burn tobacco

    MARTIN LEROY C.(1); LINDNER D.(2); HAZIZA C.(2); FORTE N.(2); MAGNETTE J.(2)
    (1) Clinopsis SA, Concise, Switzerland; (2) Philip Morris International R&D, Philip Morris Products S.A., Neuchâtel, Switzerland
    Objective: In clinical studies to assess alternative tobacco products that heat rather than burn tobacco, a compliance biomarker is needed to detect the additional use of conventional cigarettes. Standard biomarkers of exposure to cigarette smoke ...

    A modelling approach to develop machine smoking protocols reflecting human puffing behaviour for conventional cigarettes

    URBAN H-J.; GOMME W.; SCHORP M.
    Philip Morris Intl, Philip Morris Product SA, R&D, Neuchâtel, Switzerland
    Our objective was to develop machine-smoking protocols (i.e. puff volume, puff duration and puff frequency) reflecting the distribution of human smoking behaviour as a complement to the International Standard (ISO) protocol. For this purpose, a modelling ...
