Pharmacy-based PrEP for Young Women Who Sell Sex in Zimbabwe (TOPAZ)

March 29, 2024 updated by: University of California, Berkeley
Pharmacy-based PrEP for Young Women who Sell Sex in Zimbabwe is a cluster-randomized control trial and pilot study co-led by Dr. Euphemia Sibanda, Reader (Associate Professor) of Global Health and Epidemiology at Liverpool School of Tropical Medicine, UK and Research Director at the Centre for Sexual Health and HIV Research (CeSHHAR Zimbabwe) and Dr. Sandra McCoy, Professor of Epidemiology and Biostatistics at the University of California, Berkeley. The goal of the proposed study is to optimize, refine and pilot a pharmacy-based PrEP intervention for female sex workers (FSW) in Zimbabwe. Despite efforts to reach the most impacted and vulnerable populations with PrEP, retention rates, particularly among FSW in Africa, are very low. Relatively high levels of uptake indicate that FSW are interested in PrEP and ready to initiate it, but in most cases fewer than 50% of those who initiate return for medication refills by month 4. Pharmacy-based PrEP has the potential to address known barriers to PrEP retention among FSW such as stigma and access, and coupled with a small escalating incentive in the form of a gift card incentive, could also boost motivation for effective use of PrEP.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
200

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • 1) Exchanged sexual intercourse for money or gifts in past 6 months
  • 2) Age 16 or older
  • 3) HIV negative (via rapid test per national guidelines) at enrollment and no signs/symptoms of acute HIV infection

Study Plan

This section provides details of the study plan, including how the study is designed and what the study is measuring.

Design Details

  • Primary Purpose: Health Services Research
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

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: Pharmacy-based PrEP refills + gift cards
Participants who have, in addition to the standard practice of refill pickups at CESHHAR clinics, the opportunity to retrieve PrEP refills at private pharmacies, and who receive gift card incentives at the designated refill time-points of 1, 3, and 6 months.
Behavioral: Pharmacy-based PrEP refill and gift voucher
The intervention arm of this study introduces the opportunity for a pharmacy-based PrEP refill system for sex workers, coupled with financial incentives to increase adherence. Participants receive PrEP medications from selected pharmacies, a strategy designed to improve PrEP access and enhance privacy/discretion. Additionally, participants in the intervention are awarded escalating gift card values for each successful refill collection at study pharmacies, aiming to incentivize continued PrEP use for effective HIV prevention. The intervention seeks to enhance convenience and motivate adherence through financial rewards.
Experimental: Control (Standard of Care)
Participants who do not have the opportunity to retrieve PrEP refills at private pharmacies. PrEP refill pick-ups are available through CESHHAR Zimbabwe's existing network of clinical sites.
Behavioral: Control (Standard of care)
For sex workers in the control group, PrEP refill pick-up will be available through CESHHAR's existing network of clinical sites. There is no gift card incentive and no pick-up at private pharmacies.

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
PrEP retention at 6 months
Time Frame: 6 months
This will be measured as attendance within one week (before and after) of the scheduled refill visit at the 6-month visit. Outcome 1 will also be measured as follows: Proportion of visits completed as scheduled, by arm.
6 months

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.
