HIV Clinical Trial - Optimizing Smoking Cessation for People With HIV/AIDS

Status Completed

Clinical Trial Summary

The single greatest health behavior change that could improve cardiovascular morbidity and associated mortality is to assist people living with HIV/AIDS who smoke to quit. The investigators will use a factorial design to evaluate the most promising behavioral and pharmacologic treatments aimed at achieving maximal efficacy for smoking cessation among people living with HIV/AIDS who smoke. Results of this study will provide crucial, real world evidence of the best way for healthcare providers to help smokers living with HIV/AIDS quit smoking.

Clinical Trial Description

The study used a factorial design to randomize participants into 4 conditions: (1) Varenicline (12 weeks) + Positively Smoke Free (PSF) (8 weeks); (2) Varenicline (12 weeks) + Standard of Care (brief advice to quit); (3) Placebo (12 weeks) + Positively Smoke Free (8 weeks); and (4) Placebo (12 weeks) + Standard of Care. The primary outcome was the 7-day point prevalence abstinence (PPA) (<10mm) at 36 weeks. The specific aims of our proposal are: Primary Aim 1: Compare varenicline to placebo on rates of 7-day point prevalence abstinence (PPA) at 36 weeks in smokers with HIV/AIDS. We hypothesize that rates of smoking abstinence at week 36 will be higher in those treated with varenicline compared to placebo. Primary Aim 2: Compare Positively Smoke Free to low intensity, brief counseling on rates of 7-day PPA at 36 weeks in smokers with HIV/AIDS. We hypothesize that rates of smoking abstinence at week 36 will be higher in those treated with Positively Smoke Free compared to brief counseling. Primary Aim 3: Compare Positively Smoke Free + varenicline to the other two study conditions outlined above on rates of 7-day PPA in smokers with HIV/AIDS at 36 weeks. We hypothesize the effect of PSF with varenicline is greater than the effect of PSF or varenicline alone. Exporatory Aim: Explore the effect of successful cessation/smoking abstinence on levels of cardiac specific biomarkers, nicotine biomarkers, generalized markers of inflammation, lipids, coagulation and monocyte/macrophage activation. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
