About this study

Official title: Biobehavioral Interventions for HIV-negative Methamphetamine-using MSM

This study seeks to decrease methamphetamine use and concomitant high-risk sexual behaviors among methamphetamine-using men who have sex with men (MSM) by combining a biomedical intervention with a behavioral intervention. The behavioral intervention will consist of an 8-week course of contingency management (CM) through which participants will be reinforced for testing negative for methamphetamine metabolites during periodic urine analyses. The biomedical intervention involves a 28-day course of an antiretroviral drug (Truvada) to be administered after an unanticipated HIV risk exposure (i.e., engaging in either receptive or insertive anal sex without a condom with someone who is HIV-positive or of unknown status). In combining these two interventions, this study seeks to evaluate the combined intervention's effects on sexual risk behaviors and methamphetamine use.

Read the detailed description

At the baseline, all eligible participants underwent informed consent; completed baseline assessments; received rapid HIV testing; provided specimens for syphilis, gonorrhea and chlamydia testing; and received a medical examination. Those who reported a high-risk sexual or drug exposure episode with an HIV-positive or serostatus-unknown source within the preceding 72 hours immediately initiated postexposure prophylaxis. All other participants received a 4-day ''starter pack'' of Truvada to be initiated only in the case of a future high-risk exposure to HIV. All participants began the voucher-based CM intervention upon study entry. For the initial 8 weeks of study conduct, participants presented to the study site three times weekly for a urine drug screen for methamphetamine metabolites. Participants who provided urine samples that were negative for methamphetamine metabolites earned vouchers, which escalated in value for successive negative urine samples. A participant with a missing sample or a sample positive for methamphetamine metabolites did not earn vouchers. Accrued vouchers were never forfeited and could be redeemed at any time during the study for gift certificates or goods or services that promote healthy, pro-social behaviors; vouchers could not be redeemed for cash.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • TruvadaDrug

    Also called Emtricitabine and tenofovir disoproxil fumarate

    At qualifying exposure, participants will take 28 days' worth (at one pill per day) of 200 mg emtricitabine and 300 mg tenofovir DF (Truvada).

  • CMBehavioural

    Also called Contingency Management

    Participants will submit a urine sample every Monday, Wednesday, and Friday for 8 weeks (a total of 24 urine samples). Samples will be tested for methamphetamine metabolites.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Self-reported Methamphetamine Use in Previous 30 Days.

    Mean number of days (of the past 30) of methamphetamine use.

    Measured: 3-months after baseline

Secondary outcomes (3)
  1. Description of Incident STI Infections.

    Proportional 3-month incidence of syphilis, rectal gonorrhea, pharyngeal gonorrhea, and rectal Chlamydia.

    Measured: Baseline and 3-months

  2. HIV-related Sexual Risk Behaviors in Previous 30 Days.

    Self-reported episodes of Unprotected Anal Intercourse in the previous 30 days.

    Measured: 3-months after baseline

  3. Post-Exposure Prophylaxis Medication Adherence

    Median medication adherence rate, defined as the proportion of pills taken relative to the number of pills prescribed (i.e., # of pills taken / # of pills prescribed).

    Measured: 28-days

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Truvada and CM in people with Amphetamine-Related Disorders and HIV, run by Friends Research Institute, Inc. at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 27 Nov 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Self-reported Methamphetamine Use in Previous 30 Days. (time frame: 3-months after baseline). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00856323, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Sep 2016.
