Interventions to Improve the HIV PrEP Cascade Among Methamphetamine Users

May 7, 2024 updated by: Joanne Stekler, MD MPH, University of Washington
Despite increasing knowledge about and use of PrEP nationally, HIV continues to have disproportionate impact among cisgender men and transgender persons who have sex with men and transgender persons (MSM/TG), with methamphetamine (meth)-users being at particularly high risk. Building on their preliminary work, the investigators will pilot text messaging and peer navigation interventions to support PrEP use among meth-using MSM/TG with potential to be cost-effective, scalable, and easily adaptable.

Detailed Description

Despite increasing knowledge about and use of PrEP nationally, HIV continues to have disproportionate impact among cisgender men and transgender persons who have sex with men and transgender persons (MSM/TG), with methamphetamine (meth)-users being at particularly high risk. Despite apparent high levels of PrEP knowledge and exceptional insurance and medication coverage, few meth-users in Western WA have enrolled in local PrEP programs. The investigators' preliminary work with meth-using MSM/TG has identified both traditional barriers to PrEP and barriers specific for meth users, including competing priorities (e.g., getting high); lack of regularity in daily schedules leading to difficulties complying with appointments and medication adherence; and concomitant wellness and social concerns, notably depression and meth-related stigma. Additional work is needed to develop new strategies to increase PrEP uptake and support persistence and adherence among meth-using MSM/TG. Building on their preliminary work, the investigators will pilot text messaging and peer navigation interventions to support PrEP use among meth-using MSM/TG with potential to be cost-effective, scalable, and easily adaptable. The first, peer navigation, has been studied in ARV treatment and has been proposed for PrEP. The second, text messaging, has been shown to increase ARV and PrEP adherence.

Study Type

Enrollment (Actual)

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.
21

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Meets the clinic's eligibility criteria for PrEP
  • 18 years of age or older
  • HIV-negative
  • Cisgender man or individual on the trans gender variant spectrum who has sex with men
  • Ability to understand, read, and speak English
  • Reports meth use in the past 3 months
  • Has a cell phone able to send and receive text messages

Exclusion Criteria:

  • PrEP use in the prior month,
  • Discomfort or anxiety with regards to text messaging.
  • Has any circumstances that, based on the study staff's opinion, would preclude provision of informed consent, make participation unsafe, or make it unlikely the participant would be able to participate for 6 months.

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.
No Intervention: Standard of Care
Participants in this group will receive the standard of care for PrEP follow-up and no additional research interventions.
Active Comparator: Text Messaging
Participants in this group will receive the text messaging intervention.
Behavioral: Text Messaging
The text messaging intervention will send three text messages per day from a library. One will be a reminder to take PrEP, one will include PrEP information, and the third will have the content of the participant's choosing from categories of harm reduction messages and health information. Participants will also select the time period to receive these texts.
Active Comparator: Peer Navigation
Participants in this group will receive the peer navigator intervention.
Behavioral: Peer Navigation
The peer navigation intervention will provide support from a peer that is responsive to a participant's individualized needs. Peer support may include phone call reminders, help refilling PrEP prescriptions, transit assistance, or other referrals.
Active Comparator: Text Messaging and Peer Navigation
Participants in this group will receive both the text messaging and peer navigation interventions.
Behavioral: Text Messaging
The text messaging intervention will send three text messages per day from a library. One will be a reminder to take PrEP, one will include PrEP information, and the third will have the content of the participant's choosing from categories of harm reduction messages and health information. Participants will also select the time period to receive these texts.
Behavioral: Peer Navigation
The peer navigation intervention will provide support from a peer that is responsive to a participant's individualized needs. Peer support may include phone call reminders, help refilling PrEP prescriptions, transit assistance, or other referrals.

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
Acceptability of Text Messaging
Time Frame: 6 months
Self-reported likelihood to recommend the text messaging intervention, via survey response, among those who received the text messaging intervention (may have been in the Standard of care group or the Peer Navigation group). Only participants who received the text messaging intervention are included in the analysis group.
6 months
Acceptability of Peer Navigation
Time Frame: 6 months
Self-reported likelihood to recommend the peer navigation intervention, via survey response, among those who were assigned to the peer navigation group. Only participants who received the peer navigation intervention are included in the analysis group.
6 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 Persistence
Time Frame: 6 months
Persistence on PrEP comparing standard of care or text messaging vs peer navigation, as measured by whether the participant had returned to the clinic at 6 months follow up their DBS card collection.
6 months
PrEP Adherence
Time Frame: 6 months
PrEP adherence measured in dried blood spots comparing standard of care/text messaging vs peer navigation, as measured by the detection of tenofovir-diphosphate (TFV-DP) in DBS collected 6 months after study enrollment.
