A Multi-National Study To Assess How Effective And Safe The Smoking Cessation Medicine Varenicline Is In Smokers Who Have Already Tried Varenicline In The Past As A Prescription Medicine From Their Usual Healthcare Provider

May 20, 2014 updated by: Pfizer

A Phase 4 Randomized, Double-Blind, Placebo-Controlled, Multicenter Study Evaluating The Efficacy And Safety Of Re-Treatment With Varenicline In Subjects Who Are Currently Smoking, And Who Have Previously Taken Varenicline

The main purpose of this study is to compare the effectiveness and safety of the re-treatment of smokers with varenicline with placebo for smoking cessation during the last 4 weeks of a 12 week course of treatment. The study will also assess whether smokers remain abstinent at Week 24 (12 weeks after the end of treatment) and Week 52 (40 weeks after the end of treatment).

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

  • Smokers who have smoked an average of at least 10 cigarettes per day over the last 4 weeks
  • Smokers who have tried before to stop smoking at least once with varenicline, and who took varenicline for at least 2 weeks
  • The last attempt to stop smoking must be at least 3 months before entering the study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Continuous Abstinence Rate (CAR) From Week 9 Through Week 12
Time Frame: Week 9 through Week 12
The percentage of participants who, from Week 9 through Week 12, reported no smoking and no use of other nicotine-containing products since the last study visit/last contact (on the Nicotine Use Inventory) and who did not have carbon monoxide (CO)> 10ppm at any visits during this time frame.
Week 9 through Week 12

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
CAR From Week 9 Through Week 52
Time Frame: Week 9 through Week 52
The percentage of participants who, from Week 9 through Week 52, reported no smoking (Weeks 9 through 52) and no use of other nicotine-containing products (Weeks 9 through 12), or no use of other tobacco products (Weeks 13 through 52), since the last study visit/last contact (on the Nicotine Use Inventory) and who did not have CO >10 ppm at any of these visits during this time frame.
Week 9 through Week 52
CAR From Week 9 Through Week 24
Time Frame: Week 9 through Week 24
The percentage of participants who, from Week 9 through Week 24, reported no smoking (Weeks 9 through 24) and no use of other nicotine-containing products (Weeks 9 through 12), or no use of other tobacco products (Weeks 13 through 24), since the last study visit/last contact (on the Nicotine Use Inventory) and who did not have CO >10 ppm at any of these visits during this time frame.
Week 9 through Week 24
7-day Point Prevalence (PP) of Abstinence at Weeks 12, 24, and 52
Time Frame: Weeks 12, 24 and 52
The secondary endpoint of 7-day point prevalence of smoking cessation was determined by evaluating a participant's cigarette smoking status, and other nicotine (and/or other tobacco) use, based on the "last 7 days" questions in the Nicotine Use Inventory. Additionally, a participant was not considered a responder if the expired CO was >10 ppm at the time point being summarized. Participants were considered responders independently at each visit.
Weeks 12, 24 and 52

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
