Brief Summary

The overall objective of the transdisciplinary team of Human Immunology Virus (HIV) and Tobacco funded researchers is to test if tailoring nicotine replacement doses to temper these excessive levels will enhance the efficacy of the intervention. To test researchers proposed model 600 people living with HIV (PLWH) ready to quit smokers will be enrolled in a double-blind randomized clinical trial intent-to-treat design, comparing a standard well-validated brief smoking intervention, that following national guidelines + nicotine replacement therapy (NRT), versus the tailored one (brief smoking intervention + personalized doses of nicotine replacement therapy). The primary outcome for this study will be rates of smoking cessation, point prevalence abstinence (prior 7 and prior 30 days), and verified continuous abstinence 3-, 6-, and 12-months post scheduled quit day.

Detailed Description

The overall objective of the transdisciplinary team of Human Immunology Virus (HIV) and Tobacco funded researchers is to test if tailoring nicotine replacement doses to temper these excessive levels will enhance the efficacy of the intervention. This will be accomplished by assessing: 1) pre-trial plasma levels, 2) doing genotyping, which to researchers knowledge has not been used in cessation studies among people living with HIV (PLWH), and 3) providing tailored feedback to the participants, based on the assumption that the higher the knowledge and perception of risk, the higher the interest in modifying a risky behavior(s). To test researchers proposed model based in proven smoking prevention and control methods 600 PLWH ready to quit smokers will be enrolled in a double-blind randomized clinical trial intent-to-treat design, comparing a standard well-validated brief smoking intervention, that following national guidelines will consist on brief advice + nicotine replacement therapy, versus the tailored one (brief smoking intervention + personalized doses of nicotine replacement therapy (NRT). The primary outcome for this study will be rates of smoking cessation, point prevalence abstinence (prior 7 and prior 30 days), and verified continuous abstinence 3-, 6-, and 12-months post scheduled quit day. The knowledge gained here has the potential to provide a more complete bio-behavioral model to the intervention field. The proposed study if successful will provide a new tailored, replicable, and manual-based intervention for people living with HIV. It can also provide much need it information in regards to key mediators and moderators of smoking cessation interventions in this vulnerable population. Researchers long term goal is to reduce the burden of one of the most devastating causes of morbi-mortality in researchers time and improve their quality of life. The study could also pave the path to use a similar model to tailor smoking interventions for other populations (e.g., menthol users, older women, adolescents, older adults).

GroupInterventionDescription
Tailored Combination TherapyCombination TherapyCombination of Brief behavioral intervention Plus Nicotine replacement. The test product is a transdermal nicotine patch and Nicotine replacement gums for 12 weeks. The dosage of the test product depends on the amount of cigarettes used. Doses will be tailored and adjust as need it
Standard Care InterventionStandard Care InterventionBrief behavioral intervention The test product is a transdermal nicotine patch plus regular flavored gums for 10 weeks. The dosage of the test product depends on the amount of cigarettes used. Standard Flavored gums will be used as needed for 10 weeks.
Primary Outcome Measures
NameTimeMethod
Rates of Smoking Cessation12 months

verified continuous abstinence (carbon monoxide \< 10ppm and cotinine \<15 ng/mL).

Secondary Outcome Measures
NameTimeMethod
Number of Participants With Verified Continuous Abstinence12 months

verified continuous abstinence using a breathalyzer carbon monoxide \< 10ppm

Prevalence of Side Effects-safety6 through 12 months

Total number of self reported side effects from 6 through 12 months.

Change in Clinical Outcomes12 months

The investigators will analyze changes in the following parameters since baseline, and will be given one point for each parameter that improves:

* CD4 (counts and percentage).

* HIV Viral load (logs).

* Vital signs (Blood pressure in mm Hg, breaths per minute, beats per minute).

* Anthropometric measures \[Body Mass Index = weight(kilograms) / height(meters2), Waist and hip circumference in inches\].

Scale Title: Smoking Cessation Quality of Life (SCQoL) - Physical subscale Minimum 9, maximum 27 (higher scores=worse outcome)

- In health-related quality of life measured as changes in the total score of Health-Related Quality of Life survey.
