Trial summary

Injection drug use is the major mode of HIV transmission in many countries. Injection drug users (IDUs) transmit HIV not only through shared drug injection equipment but also through heterosexual and homosexual transmission and mother-to-child transmission. Read more about this study

About this study

Official title: A Phase III Randomized Study to Evaluate the Efficacy of a Network-Oriented Peer Education Intervention for the Prevention of HIV Transmission Among Injection Drug Users and Their Network Members

Injection drug use is the major mode of HIV transmission in many countries. Injection drug users (IDUs) transmit HIV not only through shared drug injection equipment but also through heterosexual and homosexual transmission and mother-to-child transmission. Studies have shown that peer education programs can reduce HIV risk behavior in IDUs. However, it is not known if reduced HIV risk behavior leads to fewer HIV infections. The purpose of this study is to find out if a peer education program can reduce the number of new HIV infections by changing the behavior of IDUs and their HIV risk contacts.

Read the detailed description

More than 20 years of research in implementing interventions for IDUs indicate that HIV transmission among these users can be prevented, slowed, and stopped with the appropriate intervention. Intervening early with multiple strategies can prevent epidemic spread and its consequences. Even after prevalence has increased substantially, prevention interventions can reduce the further spread of HIV in drug-using populations and transmission into other populations. Although research results have been promising, it is unknown if self-reported behavior change is correlated with reducing rates of HIV transmission. This study will determine the efficacy of a peer-educator, network-oriented intervention to prevent HIV transmission among substance users and their risk network members. IDUs will be recruited using street and community outreach methods in Chiang Mai and Chiang Rai, Thailand and in Philadelphia, Pennsylvania, USA.

Individuals at the study clinics will undergo a screening survey and HIV counseling and testing; they will return to the clinic to receive their HIV test results, post-test counseling, and further screening. Those who are HIV uninfected, meet preliminary eligibility requirements, and are willing to participate will be enrolled as index participants. Each index participant will be asked to identify and attempt to recruit at least two other people (potential network members) whom he/she has had sex with or taken drugs with in the 3 months prior to screening. Infected and uninfected network members will be eligible for enrollment. Index participants will be randomly assigned with their network members to either the intervention group or a control group. All participants will receive HIV counseling and regular HIV testing. Index participants assigned to the intervention group attend six, two-hour peer educator-training sessions over a period of 4 weeks. The training sessions focus on skills building and promotion of risk-reducing behaviors. A one-hour booster training session is held for index participants after their 6- and 12-month follow-up assessments.

The study will last approximately 48 months, with enrollment expected to take about 30 months. Participants will be followed for a minimum of 18 months and a maximum of 30 months. Both index participants and network members have follow-up visits every 6 months, at which they will complete surveys designed to assess HIV risk behavior, network characteristics, the intensity of the intervention delivery, and social harms that may be associated with study participation. Average network HIV incidence rates will be compared for the two study groups.

NOTE: as of January 31, 2006, the HPTN 037 trial was terminated. Participants enrolled in the study will continue to be followed at a reduced number of study visits.

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 3 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 30 Oct 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States, Thailand. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00038688, which also lists 8 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 30 Oct 2009.
