LINKED Intervention for HIV Prevention in Drug Addiction

This trial tests the LINKED social network intervention, which aims to help people who inject drugs start using PrEP (a medicine that helps prevent HIV) and MOUD (treatment for opioid addiction). Participants will join one of two groups: the LINKED intervention group, which includes a peer-led workshop, or a control group that receives general attention. The trial seeks participants in the Los Angeles area who have injected drugs in the past three months, are not currently using PrEP or MOUD, and have tested negative for HIV. As an unphased trial, this study offers a unique opportunity to contribute to innovative research that could improve health outcomes for people who inject drugs.

The trial does not specify if you need to stop taking your current medications, but you cannot be on PrEP or MOUD to participate.

Research has shown that programs like LINKED yield promising results in reducing risky behaviors among people who inject drugs. One study found that similar programs significantly reduced behaviors that increase the risk of HIV, largely due to the involvement of peer health advocates. This suggests that LINKED could be well-received and effective, as it employs a peer-driven approach to promote safer practices.

Additionally, oral PrEP (pre-exposure prophylaxis), which LINKED aims to increase the use of, has reduced HIV cases by 49% among people who inject drugs. This indicates that the intervention related to PrEP might be safe and effective.

Researchers are excited about the LINKED Intervention for HIV prevention in drug addiction because it offers a novel approach by using a peer change agent model. Unlike standard treatments that might rely on medication or more traditional counseling, LINKED involves a 3-hour workshop where participants engage in interactive learning and practice sessions. This method focuses on peer support and behavioral change, which could enhance engagement and effectiveness in preventing HIV among those struggling with drug addiction. By leveraging the influence of peers, the intervention aims to create a supportive community that facilitates positive change and adherence to prevention strategies.

Research has shown that certain programs help people who inject drugs reduce risky drug use and sexual behaviors. These programs lower the risk of HIV by encouraging healthier choices and actions. One review found that these programs lead to safer sexual practices and less drug use. In this trial, participants in the LINKED arm will receive a peer change agent intervention designed to promote healthier behaviors. Another study found that using both medication for opioid addiction and HIV treatment helps prevent and manage HIV. Overall, these programs effectively reduce HIV risk and promote healthier behaviors in this group.¹²⁵⁶⁷
