简要总结
The purpose of this research is to assess the effectiveness of two treatment strategies for smoking cessation in patients with acute recurrent pancreatitis or chronic pancreatitis who smoke cigarettes. All participants will receive varenicline, a commonly used medication that helps people stop smoking, at its standard dose. For those who are unable to stop smoking after 6 weeks of treatment, they will be randomly selected to either 1) increase their dose of varenicline, 2) combine varenicline with bupropion (another medication that helps with smoking cessation) or continue on the standard dose of varenicline. At the end of 12 weeks of treatment, participants will be asked if they have stopped smoking with confirmation done by measuring carbon monoxide levels in their breath.
详细描述
This randomized trial evaluates the safety and efficacy of varenicline-based smoking cessation treatment for patients with recurrent acute pancreatitis and chronic pancreatitis. Participants who currently smoke cigarettes and have a desire to quit smoking will be eligible to participate in this study.
Upon providing informed consent, baseline information regarding quality of life, pain, smoking history, and mental health will be collected for each participant in addition to an exhaled carbon monoxide level measurement. Participants will then be started on standard varenicline dosing for smoking cessation (1mg PO BID) for 6 weeks. Participants who continue to smoke (non-abstainers) after 6 weeks will then be randomized into 3 treatment options:
1) Increased varenicline dosing (1mg PO TID) 2) Combination of varenicline (1mg PO BID) with bupropion (150mg PO BID) or 3) Continued standard dosing of varenicline (1 mg PO BID) for an additional 6 weeks.
After 12 weeks of treatment, participants will be asked about their smoking status, have an exhaled carbon monoxide level measured and will repeat their assessments of quality of life, pain, mental health and smoking urges.

结局指标
主要结局
Proportion of participants who quit smoking at 12 weeks of treatment
时间窗: 12 weeks
This outcome measures the number of participants who quit smoking (out of the total number of participants for that intervention arm) after 12 weeks of treatment. Smoking cessation is assessed using a questionnaire that directly asks participants if they have smoked any cigarettes in the last 7 days. Smoking cessation is then confirmed by measuring an exhaled carbon monoxide level using a carbon monoxide monitor.
次要结局
- Proportion of participants who have quit smoking 24 weeks after treatment initiation(24 weeks)
- Reduction in Smoking(12 weeks and 24 weeks)
- Serious quit attempts(12 weeks)
- Treatment Engagement and Retention(12 weeks)
- Treatment Acceptability(12 weeks)
