Efficacy and Safety of Varenicline Among HIV-infected Patients (Inter-ACTIV)

July 28, 2014 updated by: ANRS, Emerging Infectious Diseases

Comparison of the Efficacy and Safety of Varenicline Versus Placebo for Smoking Cessation Among HIV-infected Patients. A Randomized Double Blind Controlled Trial

Cigarette smoking is a major cause of illness among HIV-infected patients (non-AIDS defining malignancies (especially lung cancer), non-AIDS bacterial infections and cardio-vascular diseases). Approximately 50% of HIV-infected patients are regular tobacco smokers. Tobacco smoking cessation has well known benefits on mortality and morbidity in the general population where tobacco cessation assistance programs are increasingly implemented. However, smoking cessation interventions have never been evaluated among HIV-infected patients. This trial aims at evaluating the efficacy and safety of varenicline for smoking cessation compared with placebo.

Detailed Description

Cigarette smoking is a major cause of illness among HIV-infected patients (non-AIDS defining malignancies (especially lung cancer), non-AIDS bacterial infections and cardio-vascular diseases). Approximately 50% of HIV-infected patients are regular tobacco smokers. Tobacco smoking cessation has well known benefits on mortality and morbidity in the general population where tobacco cessation assistance programs are increasingly implemented. However, smoking cessation interventions have never been evaluated among HIV-infected patients. This trial aims at evaluating the efficacy and safety of varenicline for smoking cessation compared with placebo. A pharmacokinetic study will be conducted to evaluate the effect of smoking cessation on the plasma concentration of antiretroviral treatment.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

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.

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
Time Frame
Continuous abstinence from smoking from week 9 to week 48 without the use of any other smoking cessation treatments other than trials' treatment
Time Frame: from week 9 to week 48

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
