Impact of Behavior Modification Interventions and Lung Cancer Screening on Smoking Cessation in People Living With HIV: A Feasibility Study
What this study is about
This clinical trial evaluates the usefulness of using a smartphone-based HIV-specific smoking cessation intervention at the time of lung cancer screening in helping people living with HIV quit smoking. Positively Smoke Free - Mobile may help patients with HIV quit smoking.

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Able to understand and willing to sign a written informed consent document
- HIV positive. Documentation of HIV-1 infection by means of any one of the following:
- Documentation of HIV diagnosis in the medical record by a licensed health care provider;
- Documentation of receipt of antiretroviral therapy (ART) (at least two different medications that do not constitute a prescription for pre-exposure prophylaxis \[PrEP\] or post-exposure prophylaxis \[PEP\]) by a licensed health care provider. Documentation may be a record of an ART prescription in the participant's medical record, a written prescription in the name of the participant for ART, or pill bottles for ART with a label showing the participant's name;
- HIV-1 ribonucleic acid (RNA) detection by a licensed HIV-1 RNA assay demonstrating \> 1000 RNA copies/mL;
- Any licensed HIV screening antibody and/or HIV antibody/antigen combination assay confirmed by a second licensed HIV assay such as a HIV-1 Western blot confirmation or HIV rapid multispot antibody differentiation assay. Note: The term "licensed" refers to a kit that has been certified or licensed by an oversight body within the participating country and validated internally (e.g., U.S. Food and Drug Administration \[FDA\]). WHO (World Health Organization) and CDC (Centers for Disease Control and Prevention) guidelines mandate that confirmation of the initial test result must use a test that is different from the one used for the initial assessment. A reactive initial rapid test should be confirmed by either another type of rapid assay or an E/CIA that is based on a different antigen preparation and/or different test principle (e.g., indirect versus competitive), or a Western blot or a plasma HIV-1 RNA viral load
- Receiving antiretroviral therapy and CD4 count at least 200 cells/uL within 6 months of registration (due to increased risk of LDCT false positivity with CD4 count \< 200cells/uL)
- Age 45-80 years. This age restriction reflects lung cancer risk and appropriateness for lung cancer screening; in epidemiologic studies lung cancer emerges 5-10 years earlier in PLWH, and therefore this is an appropriate risk group for screening. Although younger persons are likely to benefit more from smoking cessation as a lung cancer prevention measure, the risk/benefit ratio associated with lung cancer screening is unlikely to be optimal at ages \< 45 years for PLWH
- Biochemically confirmed current smoker (exhaled carbon monoxide \[CO\] \>= 7 parts per million)
- Meets United States Preventive Services Task Force (USPSTF) criteria for LDCT (age 50-80 and \>= 20 pack-years smoking) or high-risk but not meeting USPSTF (age 45-49 and \>= 20 pack-years smoking)
- Possession of a smartphone that can support Positively Smoke Free Mobile (PSF-M) (\> 95% of subjects had eligible phones in prior trials although researchers will include specific study screening questions assessing for adequate smartphone for the intervention)
- Sufficient literacy; \>= 4 on the Rapid Estimate of Adult Literacy in Medicine-Short Form (REALM-R) literacy scale
Exclusion criteria
- Receiving any other smoking cessation interventions currently or within the prior 30 days
- Contraindication to nicotine replacement therapy
- Pneumonia or serious lung infection in prior 12 weeks
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active major infection, malignant tumors (unless these tumors were: (a) completely resected basal cell or squamous cell skin carcinomas or (b) in-situ squamous cell carcinoma of the cervix or anus), or any other major uncontrolled comorbid condition that would limit life expectancy or psychiatric illness/social situations that would limit compliance with study requirements
- History of lung cancer
- Pregnant women are excluded from this study because computed tomography introduces radiation exposure and may have teratogenic effects
- Women who are breastfeeding (the safety of nicotine replacement therapy has not been established with breastfeeding)
- Received a chest computed tomography scan in the previous twelve months

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
