A Phase 2 clinical trial evaluating X-22 Smoking Cessation Product and Active Control Cigarettes for Smoking Cessation. Completed, enrolled 234 participants across 3 sites.

Detailed Summary

A randomized, active controlled clinical trial in which a total of 216 healthy smokers will be enrolled and followed over approximately 19 weeks. The trial will evaluate the efficacy and safety of using X-22 as a smoking cessation aid. Healthy smokers who plan to quit smoking will be screened for eligibility. Subjects will be randomized in a 1:1 ratio to 1 of the 2 treatment arms: * Group 1: X-22 Cigarettes (very low nicotine) * Group 2: Active Control Cigarettes The randomization will be stratified by gender. Efficacy will be assessed by analysis of cigarette consumption using self-report diaries and measurement of exhaled carbon monoxide (CO) and cotinine concentrations.
