Impact of Very Low Nicotine Content Cigarettes in a Complex Marketplace

Nicotine Dependence Clinical Trial

Official title: Impact of Very Low Nicotine Content Cigarettes in a Complex Marketplace Part of "Evaluating New Nicotine Standards for Cigarettes"

Status Completed

Clinical Trial Summary

This project will examine the impact of very low nicotine content (VLNC) cigarettes in a complex tobacco and nicotine product marketplace. We will compare the number of cigarettes smoked and cigarette-free days in an experimental marketplace that contains VLNC cigarettes versus normal nicotine content (NNC) cigarettes.

Clinical Trial Description

This randomized, open label, controlled, multi-site study will simulate a "real world" tobacco environment by providing participants access to an experimental marketplace where they will be given vouchers for a specified number of points that can be exchanged for study cigarettes (varying in nicotine content described below) and non-combusted tobacco/nicotine products (smokeless tobacco, snus, electronic cigarette, medicinal nicotine replacement) and at the end of the study can exchange unspent points for money.

Subjects (N=200 in each group) will be randomly assigned to: 1) very low nicotine content cigarettes (VLNC; 0.4 mg/g) along with non-combusted tobacco/nicotine products or 2) normal nicotine content cigarettes (NNC; 15.8 mg/g) along with non-combusted tobacco/nicotine products.

Smokers will undergo an orientation visit for screening and then enter a three phase experimental trial:

1. Phase 1 - Baseline: Two week baseline assessment period during usual brand cigarette smoking.

2. Phase 2 - Marketplace Adaptation: Two week period where subjects have access to the marketplace that provides their preferred usual brand cigarettes and selected non-combusted tobacco products to allow the subject to adjust to the marketplace prior to randomization;

3. Phase 3 - Intervention: Randomization to a marketplace with access to either VLNC or NNC cigarettes plus non-combusted products for a 12 week period.

Biomarker samples are collected at baseline, end of Phase 2 and end of week Phase 3 (week 12). ;
