Private-sector Access to Testing for Health Sustainability (PATHS)

April 14, 2026 updated by: University of California, San Francisco

Expanding Access to HIV Self-test Kits: Sustaining Private Sector Channels That Enable Access to Preventive Health Services

New and innovative strategies are urgently needed to increase the uptake of HIV prevention and sexual and reproductive health services among adolescent girls and young women (AGYW) in sub-Saharan Africa. To ensure the real-world sustainability of free distribution of HIV self-test kits to AGYW by private drug shops and pharmacies, investigators will rigorously test supply-side subsidy structures for shopkeepers' provision of HIV-self test kits to AGYW combined with prosocial motivational supports. The combination of non-monetary and monetary support structures aims to emulate real-world health financing models for public-private partnerships and ultimately aims to improve equity in access to critical prevention services for AGYW at scale.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Not yet 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

This is an implementation-effectiveness trial that tests program adoption, implementation, and maintenance of free HIV self-test kit (HIVST) distribution to adolescent girls and young women (AGYW) financed by profits from HIVST kit sales to non-AGYW customers. To initiate adoption, the study will offer pharmacy and drug shopkeepers the opportunity to procure subsidized HIVST to simultaneously distribute to AGYW for free (reimbursed by the study mimicking government-supported provision) and sell to non-AGYW customers for profit, gradually phasing out procurement subsidies over 36 months to test maintenance of the segmented pricing model for real-world sustainability (Aim 1). Investigators will implement non-monetary motivation boosters to sustain shopkeeper engagement over the study period and use mixed-methods to understand shopkeepers' experiences and necessary conditions for program maintenance and provider behavior change (Aim 2), which will inform the co-design of a progressive scale-up plan to achieve national coverage with Tanzanian AGYW, public, and private partnership stakeholders (Aim 3). At the study's conclusion, investigators will have a comprehensive understanding of the support structures shops need to sustain HIVST kit provision for AGYW. Importantly, the study will contribute to generalizable learning about the structures required for commercially sustainable public-private partnerships for high-impact public health 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.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: High subsidy
The high subsidy group will start off with a 90% subsidy for purchasing HIV self-test kits to sell in their shops.
Behavioral: High HIVST kit subsidy
The two study groups are the "high" and "low" subsidy groups. The high subsidy group will start off with a 90% subsidy while the low subsidy group will start off with a 50% subsidy. Both study groups will experience decreasing subsidies at each phase of the study.
Active Comparator: Low subsidy
The low subsidy group will start off with a 50% subsidy for purchasing HIV self-test kits to sell in their shops.
Behavioral: Low HIVST kit subsidy
The two study groups are the "high" and "low" subsidy groups. The high subsidy group will start off with a 90% subsidy while the low subsidy group will start off with a 50% subsidy. Both study groups will experience decreasing subsidies at each phase of the study.

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: 39 months
HIVST kit distribution per shop per month will be tracked via Maisha Meds sales and inventory management system. The data from Maisha Meds will include a tag that identifies the kit recipient as an AGYW and will include the price paid for the HIVST kit ($0 for AGYW).
39 months

Plan for Individual participant data (IPD)

Plan to Share Individual Participant Data (IPD)?

YES

IPD Plan Description

This project will produce survey data, in-depth interview transcripts, and product sales and distribution data. All data will be de-identified prior to receipt by the repository, but the information needed to generate a global unique identifier (GUID) for the NIMH Data Archive (NDA) will be collected for each subject if possible. This information includes First Name, Middle Name, Last Name, Sex, Date of Birth, City/Municipality of Birth. Because investigators are collecting data from participants in Tanzania, some of this information may be unavailable or may not meet the requirements for the GUID. In that case, pseudoGUIDs will be utilized.

IPD Sharing Time Frame

The research community will have access to data when the award ends. As required by NDA, studies will also be created that contain the data used for every publication. Those studies will be shared when the pre-print is available. NDA studies have digital object identifiers (DOI) to aid in findability. Investigators will include that DOI in relevant publications. NDA will make decisions about how long to preserve the data, but that data archive has not deleted any deposited data up to now.

IPD Sharing Access Criteria

To request access of the data, researchers will use the standard processes at NDA, and the NDA Data Access Committee will decide which requests to grant. The standard NDA data access process allows access for one year and is renewable.
