Assessing E-Cigarettes for Tobacco Harm Reduction in the Context of Lung Cancer Screening
- Conditions
- Electronic Cigarette UseSmoking, CigaretteNicotine Dependence
- Interventions
- Other: NJOY ACE e-cigarette
- Registration Number
- NCT06472869
- Lead Sponsor
- Massachusetts General Hospital
- Brief Summary
This study investigates the feasibility, acceptability, and short-term effects of providing 4 weeks of complimentary electronic cigarettes (ECs) to 30 individuals who did not quit after smoking cessation treatment provided in the context of lung cancer screening and do not plan to quit smoking. This open-label single-arm pilot clinical trial will test the impact of EC provision on: 1) study feasibility, 2) EC acceptability, 3) tobacco use behavior (e.g., cigarettes per day, EC use), and 4) biomarkers (e.g., carbon monoxide, cotinine, and anabasine). Participants will be asked to switch from combustible cigarettes to the NJOY ACE 5% nicotine electronic cigarette (EC) for 4 weeks. They will be followed an additional 4 weeks after EC provision ends (to 8 weeks).
The first study hypothesis is that more than 40% of eligible smokers who are offered participation in the trial will enroll, and that 75% of enrollees will complete the trial. The second study hypothesis is that participants will report fewer cigarettes smoked per day at the end of 4 weeks of EC provision, relative to their baseline values.

- Hospitalized for acute coronary syndrome, unstable angina, congestive heart failure, stroke, pneumonia or chronic pulmonary disease/asthma exacerbation in the past 1 month

Group Intervention Description NJOY ACE e-cigarette provision NJOY ACE e-cigarette Device: NJOY ACE e-cigarette, 5% nicotine in tobacco flavor Patients will be provided with a NJOY ACE electronic cigarette for 4 weeks and asked to use the NJOY ACE as a substitute for smoking combustible cigarettes during the 4 weeks.
- Primary Outcome Measures
Name Time Method Study feasibility 4 weeks Participant enrollment, measured by the proportion of eligible participants following in-person screening who enroll in the study. Retention is measured by weeks of study participation.
Cigarettes per day (CPD) smoked during the period of e-cigarette provision 4 weeks Change in self-reported CPD smoked in the past week assessed using timeline follow-back (TLFB) between baseline and end of e-cigarette provision (Baseline vs.Week 4)
- Secondary Outcome Measures
Name Time Method Carbon monoxide (CO) concentration in expired air 4 weeks Change in participant's expired air carbon monoxide (CO) concentration assessed via Smokerlyzer during the period of e-cigarette provision (Baseline vs.week 4)
Urine cotinine concentration 4 weeks Change in concentration of cotinine (nicotine metabolite) in participant's urine during e-cigarette provision (baseline to week4)
Urine anabasine concentration 4 weeks Change in participant's urine anabasine concentration during the period of e-cigarette provision (baseline to week 4)
Cigarettes smoked per day after e-cigarette provision ends 4 weeks (Weeks 4-8) Self-reported number of cigarettes smoked per day in the past week between end of e-cigarette provision and end of study (week 4 to week 8)
