Adapting and Evaluating a Tobacco Use Cessation Program for People Living With HIV in Uganda and Zambia (Quit4Life)

November 27, 2023 updated by: Heather Wipfli, University of Southern California

Quit4Life+: Adapting and Evaluating a Phone-Based Tobacco Use Cessation Program for People Living With HIV in Uganda and Zambia (Quit4Life+ )

This proposal tests the efficacy of a phone-based tobacco cessation intervention for people living with HIV (PLWH) in comparison to the standard of care (brief advice to quit) and nicotine replacement therapy (nicotine patches) in Uganda and Zambia. This study will provide insight into the efficacy, feasibility, applicability, and affordability of delivering tobacco cessation interventions through health care professionals at HIV treatment centers in two countries with different tobacco use patterns, policy environments, and health care resources. The previously tested SMS-platform to be used in this study is uniquely positioned to be scaled in low- and middle-income countries worldwide, in which case rigorous research showing even modest success in reducing the prevalence of tobacco consumption among PLWH could confer substantial health and economic benefits.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

While there is substantial evidence supporting interventions to help tobacco users in the general population quit, little is available relevant to the challenges facing HIV+ tobacco users, especially those living in low-income African countries. This study approaches this gap with the first randomized control trial (RCT) to test the efficacy of a tailored short message service (SMS) based tobacco use cessation intervention on prolonged tobacco use abstinence at 6 months post program initiation in comparison to the standard of care (brief advice to quit) and nicotine replacement therapy (nicotine patches) among PLWH in Uganda and Zambia. This study will provide insight into the efficacy, feasibility, applicability, and affordability of delivering tobacco cessation interventions through health care professionals at HIV treatment centers in two countries with different tobacco use patterns, policy environments, and health care resources and provide needed information to providers and policymakers looking for cost-effective tobacco cessation interventions.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Prolonged tobacco abstinence
Time Frame: 6 months post enrollment
The primary outcome for this efficacy trial is the proportion of study participants that have prolonged abstinence (i.e., no tobacco use from the target quit date through follow-up) at 3 and 6 months post enrollment measured by self-report and biochemically-verified as recommended by the Society for Research on Nicotine and Tobacco, the biomarker being assessed is urinary cotinine (<12 ng/mL) at 6 months post enrollment
6 months post enrollment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Point Prevalence
Time Frame: 4 weeks, 8 weeks, and 3 months post enrollment
7 consecutive days of no tobacco use, biochemically-verified at 4 weeks, 8 weeks, and 3 months post enrollment, the biomarker being assessed is urinary cotinine (<12 ng/mL) at 6 months post enrollment, the measurement tool is urine cotinine dip sticks
4 weeks, 8 weeks, and 3 months post enrollment

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.

Plan to Share Individual Participant Data (IPD)?

NO

IPD Plan Description

Our dissemination strategy will target tobacco and HIV stakeholders including Ministry of Health and other government officials, health care organizations, health facility managers, HIV health care providers, tobacco control professionals, non-governmental organizations engaged in HIV and tobacco control, and PLWH. Our investigators will publish study results through peer-reviewed journals and scientific conferences; generate fact sheets and policy briefs; and disseminate our results through websites, social media, television and radio. We will share the study results in the participating Districts and the Cancer Treatments Centers of America will host a workshop in the final year with regional stakeholders to share the study results and promote tobacco use cessation programming for PLWH throughout Sub-saharan Africa. World Health Organization will assist in disseminating the study findings to other low/middle income countries.
