Interventions to Improve the HIV PrEP Cascade Among Methamphetamine Users

An interventional study of Text Messaging and Peer Navigation in HIV/AIDS, Adherence, Medication and Drug Use, sponsored by University of Washington. Completed at 2 sites in United States. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-06-05.

Study summary

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.

Read the 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.

    Behavioral: Text Messaging · Behavioral: Peer Navigation

Interventions

  • BehavioralText 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.

  • BehavioralPeer 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 researchers measure

Primary outcomes

  1. Acceptability of Text Messaging

    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.

    Time frame: 6 months

  2. Acceptability of Peer Navigation

    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.

    Time frame: 6 months

Secondary outcomes

  1. PrEP Persistence

    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.

    Time frame: 6 months

  2. PrEP Adherence

    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.

    Time frame: 6 months

Limitations and caveats
Data collected via surveys may have been impacted by social desirability bias. While the HMU! cohort represented some populations disproportionately impacted by methamphetamine and HIV, there were key populations we did not reach. Alaskan Native and Native American and Hispanic/Latinx MSM were under represented in our study, as were individuals who were not cisgender.
