Clinical Trial Summary

Two-arm, parallel-group, non-crossover, single-center pilot randomized controlled trial, enrolling up to 180 participants to evaluate the effect of the Pivot smoking cessation program (intervention) compared to usual care (commercially available app smoking cessation program plus optional nicotine replacement therapy, control).

Description:

The present pilot randomized controlled trial compares user engagement and retention, change in attitudes towards quitting smoking, change in smoking behavior and participant feedback in adult smokers randomized either to the Pivot (intervention) or commercially available (control) smoking cessation programs.

We aim to assess participants' use of Pivot program and commercially available program. There will be a focus on assessing use and engagement, changes in attitudes towards quitting smoking and changes in smoking behavior over the course of the 2-year study, as well as participant feedback on the set-up, design, use experience, and impact of each program.
