Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are Black/African American and Hispanic/Latina cisgender women who are HIV negative, diagnosed with a substance use disorder, and sexually active with an opposite sex partner.

Probably not a fit

Patients who are currently participating in another substance use disorder treatment program or are ineligible for PrEP based on CDC criteria may not benefit from this study.

What this trial studies

This clinical trial aims to evaluate a behavioral intervention designed to enhance the uptake and adherence of Pre-Exposure Prophylaxis (PrEP) among Black/African American and Hispanic/Latina women with substance use disorders. Participants will receive four counseling sessions, prevention navigation, and nurse practitioner-prescribed PrEP within an addiction treatment setting. The study will compare the effectiveness of this integrated intervention against standard treatment to determine its impact on PrEP adherence and uptake.

Why it matters

Potential benefit: If successful, this intervention could significantly improve HIV prevention among women with substance use disorders.

How similar studies have gone: While there have been studies focusing on PrEP adherence, this specific integrated intervention approach targeting women with substance use disorders is relatively novel.
