Investigating new HIV prevention methods and their effectiveness against acute infections

ACTION: Study of ACuTe Infections On Novel HIV Prevention Modalities

NIH-funded research University of California, San Francisco · NIH-10849753

This study is looking at new ways to help prevent HIV, like a special vaginal ring and an injection, to see if they can make it easier for people to stay protected without having to take daily pills, especially for those in sub-Saharan Africa.

What this research studies

This research focuses on improving HIV prevention strategies by evaluating new long-acting antiretroviral (ARV) options, such as the dapivirine vaginal ring and injectable cabotegravir. These methods aim to reduce reliance on daily medication adherence, which can be a barrier for many individuals. The study will assess the occurrence of acute HIV infections among users of these new prevention modalities and explore factors like ARV resistance that may impact their effectiveness. Participants may be involved in trials assessing how well these products work in real-world settings, particularly in sub-Saharan Africa.

Who could benefit from this research

Good fit: Ideal candidates for this research include individuals at high risk for HIV who are considering or currently using PrEP methods.

Not a fit: Patients who are not at risk for HIV or those who are already on effective treatment regimens may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to more effective HIV prevention methods that are easier for patients to use and adhere to.

How similar studies have performed: Previous research has shown promise in the effectiveness of long-acting PrEP methods, but this study aims to address specific challenges related to acute infections and drug resistance.
