Further study details as provided by Swedish Match AB:

Primary Outcome Measures:
  • Smoking reduction defined as a reduction in self-reported number of smoked cigarettes per day >50% compared to base-line, verified by a reduction in CO in exhaled air of >1 ppm compared to base-line [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Smoking cessation defined as self-reported total abstention from cigarettes verified by CO in exhaled air <10 ppm [ Time Frame: 3, 6, 9 and 12 months ] [ Designated as safety issue: No ]
  • Clinical tests and biomarkers relevant for exposure to tobacco [ Time Frame: 3, 6, 9, and 12 months ] [ Designated as safety issue: Yes ]
  • Smoking reduction [ Time Frame: 12, 24, 36 and 48 months ] [ Designated as safety issue: No ]
    Smoking reduction according to self-report

  • Smoking reduction [ Time Frame: 12, 24, 36 and 48 months ] [ Designated as safety issue: No ]
    Smoking reduction compared to baseline according to self-report
