Official title

Testing Novel Pharmacogenetic and Adherence Optimization Treatments to Improve the Effectiveness of Smoking Cessation Treatments for Smokers With HIV

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The advent of anti-retroviral therapy (ART) for people living with HIV/AIDS (PLWHA) substantially improved life expectancy but has also led to the critical need to address modifiable risk factors associated with cancer and cardiovascular disease, such as tobacco smoking. HIV-infected smokers lose more life-years due to tobacco use than they do to their HIV infection. There have been relatively few studies of tobacco use treatments for PLWHA and systematic reviews show that there are insufficient data to conclude that tobacco dependence interventions that are efficacious in the general population are efficacious for PLWHA. Further, many studies in this area have lacked randomization and a control group, infrequently used an intent-to-treat (ITT) approach and biological verification of tobacco abstinence, and lacked post-treatment follow-up.10 What investigators do know thus far is that behavioral interventions and the nicotine patch yield moderate effects on cessation; and 2 recent placebo-controlled trials - one in France and one by this lab - found that varenicline is safe and effective for treating tobacco use among PLWHA, but yield quit rates that are substantially lower than those reported in the general population. Thus, there is a critical need to rigorously test novel ways to optimize tobacco cessation treatment for smokers with HIV.
