What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a mobile app and a medication to help people with HIV quit smoking. The app provides tips and support, while the medication reduces cravings. The study aims to see if this combination is more effective than standard care.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, you must be able to use varenicline safely, which will be evaluated by your primary provider.

Is the combination of Varenicline and PSF-M safe for smoking cessation in people with HIV/AIDS?

Varenicline, used for smoking cessation, has been studied in people with HIV and is generally considered safe, though common side effects include nausea and sleep disturbances. Serious side effects are rare, but monitoring for changes in mood or behavior is recommended. In studies, it did not negatively affect HIV treatment outcomes. ^{1 2 3 4 5}

How is the drug varenicline unique for smoking cessation in people with HIV/AIDS?

Varenicline is unique for smoking cessation in people with HIV/AIDS because it has been specifically studied for safety and effectiveness in this population, showing it can help reduce smoking without negatively affecting HIV treatment outcomes. It works by reducing nicotine withdrawal symptoms and cravings, and it has been found to be more effective than some other smoking cessation aids like bupropion. ^{1 2 3 6 7}

What data supports the effectiveness of the drug Varenicline for smoking cessation in people living with HIV/AIDS?

Research shows that Varenicline is effective for helping people with HIV quit smoking, with a 42% abstinence rate in one study. It also does not negatively impact HIV treatment and may improve psychological well-being, such as reducing depression and anxiety. ^{1 3 6 8 9}

Published Research Related to This Trial

In a clinical trial involving 179 people living with HIV/AIDS, varenicline significantly increased smoking cessation rates at Week 12 compared to placebo, with 28.1% of participants quitting versus 12.1%.

Varenicline was found to be safe, with no significant differences in treatment-related side effects or adverse events compared to placebo, making it a viable option for short-term smoking cessation in this population.

Placebo-controlled randomized clinical trial testing the efficacy and safety of varenicline for smokers with HIV. Ashare, RL., Thompson, M., Serrano, K., et al.[2023]

In a study involving 248 people living with HIV, varenicline combined with counseling significantly increased the rate of smoking cessation compared to placebo, with 15% of participants in the varenicline group achieving continuous abstinence from weeks 9 to 48.

The safety profile of varenicline was favorable, showing a lower incidence of depression in the varenicline group (2%) compared to the placebo group (10%), indicating that varenicline is a safe and effective option for smoking cessation in this population.

In a study of 179 people living with HIV/AIDS, quitting smoking did not negatively impact adherence to anti-retroviral therapy (ART), which remained above 98% for all participants.

Participants who successfully quit smoking reported significant reductions in depression and anxiety symptoms, along with increased life satisfaction, suggesting that smoking cessation can have positive psychological effects for individuals with HIV/AIDS.

Improved clinical outcomes among persons with HIV who quit smoking. Lubitz, SF., Flitter, A., Ashare, RL., et al.[2021]

In a study of 47 daily smokers, those taking varenicline showed slower relapse rates and higher total abstinence after experiencing a programmed smoking lapse compared to those on a placebo.

Varenicline appears to reduce the perceived reward and effects of smoking, which may help prevent relapse during quit attempts, highlighting its effectiveness as a smoking cessation aid.

In a pilot study involving 36 HIV-infected smokers, varenicline was found to be safe and effective for smoking cessation, with a 42% rate of verified continuous abstinence over 4 weeks.

The treatment did not adversely affect HIV viral load, and CD4 counts increased significantly, indicating that varenicline can be a viable option for smoking cessation in this population, despite common side effects like nausea.

In a randomized controlled trial, varenicline (Chantix) demonstrated a higher abstinence rate from smoking after one year compared to both bupropion SR (Zyban) and a placebo, indicating its efficacy in treating tobacco dependence.

Despite its effectiveness, varenicline has been associated with serious neuropsychiatric side effects, highlighting the importance of discussing potential risks and benefits with patients considering this treatment.

Treatment of nicotine dependence with Chantix (varenicline). Rankin, KV., Jones, DL.[2015]

Varenicline is an effective treatment for tobacco addiction, showing improved quit rates compared to other therapies, and is safe for use in both healthy smokers and those with cardiovascular or pulmonary issues, as well as smokeless tobacco users.

While varenicline is generally well-tolerated, there have been concerns about potential neuropsychiatric side effects, leading to updated monitoring guidelines, although most studies did not find a significant link to serious psychiatric symptoms, except for sleep disorders.

NCBI (Pubmed)

pubmed.ncbi.nlm.nih.gov

Varenicline in smoking cessation. Tonstad, S., Rollema, H.[2017]

In a review of ten randomized controlled trials involving 3091 participants, varenicline did not show a significant increase in overall psychiatric disorders compared to placebo, with an incidence of 10.7% in the varenicline group versus 9.7% in the placebo group.

While varenicline was associated with a higher incidence of sleep disorders, there were no reported cases of suicidal ideation or behavior in the analyzed studies, suggesting that varenicline is generally safe for smokers without current psychiatric conditions.

Psychiatric adverse events in randomized, double-blind, placebo-controlled clinical trials of varenicline: a pooled analysis. Tonstad, S., Davies, S., Flammer, M., et al.[2022]

Varenicline, when used for smoking cessation in HIV-infected individuals, has a safety profile similar to that observed in non-HIV smokers, with common side effects including nausea and sleep problems, but no significant cardiovascular issues reported.

Preliminary results indicate that varenicline is more effective than nicotine replacement therapy (NRT) for promoting smoking abstinence, with a confirmed abstinence rate of 25.6% in the varenicline group compared to 11.8% in the NRT group, suggesting that varenicline could be a preferred treatment option for this population.
