HIV Clinical Trial

Official title: Optimizing Smoking Cessation for People With HIV/AIDS Who Smoke

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. ;
