What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants With 7-day Point Prevalence of Smoking Cessation at Week 4

    Participants who abstained from smoking in last 7 days. Abstained = response of no to both Nicotine Use Inventory questions: "In last 7 days has subject 1) smoked any cigarettes (even a puff)?, and 2) used any other nicotine-containing products?". Participants who discontinued study were counted as a smoker for the 7-day point prevalence from the timepoint of discontinuation through end of study.

    Measured: Week 4

  2. Percentage of Participants With 7-day Point Prevalence of Smoking Cessation at Week 8

    Participants who abstained from smoking in last 7 days. Abstained = response of no to both Nicotine Use Inventory questions: "In last 7 days has subject 1) smoked any cigarettes (even a puff)?, and 2) used any other nicotine-containing products?". Participants who discontinued study were counted as a smoker for the 7-day point prevalence from the timepoint of discontinuation through end of study.

    Measured: Week 8

  3. Percentage of Participants With 7-day Point Prevalence of Smoking Cessation at Week 12

    Participants who abstained from smoking in last 7 days. Abstained = response of no to both Nicotine Use Inventory questions: "In last 7 days has subject 1) smoked any cigarettes (even a puff)?, and 2) used any other nicotine-containing products?". Participants who discontinued study were counted as a smoker for the 7-day point prevalence from the timepoint of discontinuation through end of study.

    Measured: Week 12
