Integrated Treatment and Prevention for People Who Inject Drugs

This is a multi-site, two-arm, randomized, vanguard study. Network units will consist of an HIV-infected index participant and his/her HIV-uninfected network injection partner(s). Network units will be randomized to the intervention or standard of care arms in a 1:3 ratio, stratified by site. To assess feasibility of the intervention, additional interviews will be conducted with study staff (systems navigators and counselors) and clinic-based stakeholders at each study site.

Approximately 500 Index participants and their partners will be enrolled.
