简要总结
The objective of this study is to determine whether treatment with random nicotine delivery via a nicotine film both before and after the target quit date will facilitate smoking cessation relative to treatment with steady state delivery or placebo.
The investigators hypothesize that smoking cessation will be greater in subjects assigned to a random nicotine delivery regimen (as compared to those assigned to a steady state or placebo regimen). The nicotine film product is not part of the standard of care and is not available in non-investigational settings in the United States.
详细描述
This project is a prospective parallel-group, randomized, double-blind, placebo-controlled study in which 45 current cigarette smokers who are interested in quitting will be randomly allocated to one of three possible nicotine film treatment regimens:
- Random nicotine delivery (a combination of four 0 mg and 4 mg films daily not to exceed three non-consecutive 4 mg films in one day and to maintain an average of 8 mg of nicotine per day through 7 days for 6 weeks total).
- Steady state nicotine delivery (2, 2, 2, 2 mg films daily for 6 weeks total)
- Placebo delivery (0, 0, 0, 0 mg films daily for 6 weeks total)
Prior to assignment in one of the above treatment groups, all participants will take part in a 1-week baseline period to assess normal smoking behavior and nicotine dependence. Following randomization to their assigned treatment group at Visit 2, participants will be instructed to smoke cigarettes as they feel necessary over the next two weeks while using the nicotine films as directed (i.e., one film every 3-4 hours for a total of four films per day). After two weeks of pre-cessation treatment, participants will be asked completely cease cigarette smoking and to only use their assigned nicotine films as directed. Participants will be supported in their quitting efforts with regular contacts both in person at the Penn State Milton S. Hershey Medical Center and over the phone.

Steady State Nicotine Delivery
One 2 mg nicotine film every 3-4 hours for a total of four films per day for 6 weeks.
干预措施: Nicotine Film (Drug)

结局指标
主要结局
Change in Exhaled Carbon Monoxide (CO) Measurement
时间窗: Baseline and 4 weeks after Target Quit Date
Mean change in exhaled CO (parts per million \[ppm\])
Change in Number of Cigarettes Smoked Per Day (CPD)
时间窗: Baseline and 4 weeks after Target Quit Date
CPD is measured with the use of daily cigarette logs which are completed daily by participants and returned to the study center at each visit. The CPD measure will be the average of the past 7 days.
次要结局
- Change in Questionnaire of Smoking Urges-Brief (QSU-Brief) Total Score(Baseline and 4 weeks after Target Quit Date)
- Subjective Ratings Scale for Nicotine Film Use(4 weeks after Target Quit Date)
- Change in Fagerstrom Test for Nicotine Dependence (FTND) Total Score(Baseline and 4 weeks after Target Quit Date)
- Side Effects From Nicotine Film Use(4 weeks after Target Quit Date)
