    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

    (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...
