Exploring the cessation efficacy and harm reduction potential of heated tobacco and nicotine pouch products in smokers and smokeless tobacco users: study protocol of a 6-month randomized controlled switching trial
Background: Despite decades of research on pharmacological and behavioural smoking cessation treatments, current quit aids are of limited success. The introduction of new, combustion-free nicotine and tobacco products extended the tool kit for people who smoke to switch away from their risky habit. We performed a systematic review including 120 studies resulting in several recommendations for a robust study design to determine the cessation efficacy of a new nicotine or tobacco product. Consequently, we prepared this study protocol to assess the cessation efficacy of heated tobacco products (HTPs) and nicotine pouches (NPs).
Methods: 250 subjects (125 exclusive smokers and 125 exclusive smokeless tobacco (SLT) users) will be recruited and offered a choice of HTPs in case of smokers and a choice of NPs in case of SLT users in order to switch. Subjects will undergo four visits (baseline, 1, 3, and 6 months) to collect biospecimens and for physical examinations. Use behaviour and questionnaires will be monitored on a regular basis by means of a smartphone-app. We describe a sensitive and specific compliance monitoring using suitable biomarkers of exposure. The sample size of 250 subjects and duration of 6 months will allow the quit rates to be assessed with sufficient statistical power. Finally, the choice between different products shall reflect the individuals’ preferences.
Conclusions: This protocol can be applied generically, providing a robust determination of a products’ cessation efficacy.
Trial Registration: The trial will be registered in the International Clinical Trials Registry Platform.
