The Prevention Options for Women Evaluation Research (POWER) Cohort

December 2, 2021 updated by: Connie Celum, University of Washington

A Cohort for Evaluation of Open-label PrEP Delivery Among Kenyan and South African Women: The POWER Cohort

The POWER Cohort study is a PrEP implementation project to demonstrate Pre-exposure prophylaxis (PrEP) delivery for young women in Cape Town and Johannesburg, South Africa and Kisumu, Kenya.

Study Overview

Status

Status

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

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

PrEP will be delivered to young women according to emerging national guidelines in family planning clinics (Kisumu, Kenya), youth friendly clinics (Johannesburg, South Africa), and mobile youth friendly clinics (Cape Town, South Africa). The investigators will evaluate PrEP delivery and follow cohorts of young women at each clinic location to understand PrEP uptake and use. In the Kisumu clinics, the investigators will also offer expedited partner therapy and partner HIV self-tests to women who test positive for chlamydia and/or gonorrhea. At one clinic in Johannesburg, the investigators will evaluate the use of a decision support tool to improve the decision to initiate PrEP.

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

16 years to 25 years (ADULT, CHILD)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

Sexually active HIV uninfected women ages 16-25 will be recruited from family planning clinics, youth clinics, and youth outreach programs.

Description

Inclusion Criteria:

  • Age 16-25 (16 and 17 year olds, where permissible by national regulations and local IRB approval)
  • Able and willing to provide written informed consent
  • Recently sexually active (defined as having had vaginal intercourse at least once in the previous three months)
  • HIV uninfected based on negative HIV rapid tests, on the date of enrollment

Design Details

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Young women
Sexually active HIV-uninfected women between 16-25 years of age will be given Truvada.
Drug: Truvada
A fixed dose of oral co-formulated tenofovir disoproxil fumarate (TDF)/emtricitabine (FTC) will be used as PrEP.

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
Demonstrate PrEP delivery models for young women in different settings and geographies.
Time Frame: Up to 36 months
Mixed methods assessment of how PrEP is implemented at the user, provider, health care facility, and community levels.
Up to 36 months

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
PrEP initiation
Time Frame: Up to 36 months
Measure the number of young women who initiate PrEP.
Up to 36 months
PrEP adherence
Time Frame: Up to 36 months
Adherence by young women to PrEP. Adherence will be measured by the timing of PrEP refills and self-reported PrEP use. Blood samples for detection and quantification of PrEP levels (testing in batch) will be done for those who seroconvert to HIV and a subset who remain HIV uninfected.
Up to 36 months
HIV seroconversion
Time Frame: Up to 36 months
Assess HIV incidence during PrEP use and non-use.
Up to 36 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.
Outcome Measure
Measure Description
Time Frame
Assess cost and cost-effectiveness of PrEP when delivered in public health clinics.
Time Frame: Up to 36 months
Time-motion studies will be conducted to define the cost and cost effectiveness of the intervention in terms of HIV infections averted, disability-adjusted life years saved, and incremental cost-effectiveness of PrEP over routine HIV care.
Up to 36 months
Evaluate the acceptability of delivering expedited partner therapy.
Time Frame: Up to 36 months
Measure the number of women who accept STI expedited partner therapy and HIV self-test kits for their partners.
Up to 36 months
Assess the effect of a decision support tool on PrEP uptake
Time Frame: Up to 36 months
Using a randomized design, evaluate if a decision support tool increases PrEP uptake.
Up to 36 months
Evaluate the impact of HIV self-testing on PrEP delivery among young women receiving PrEP
Time Frame: Up to 12 months
Using a pretest posttest design, evaluate the feasibility of integrating HIV self-testing into PrEP delivery.
Up to 12 months
