- NCT06665646RecruitingPhase 1
HIV vaccine booster study for previous trial participants
This study tests a booster vaccine for HIV in people who were part of an earlier HIV vaccine trial. The goal is to see if it's safe and helps the immune system fight HIV better.

La Jolla, CaliforniaAges 18 years+ - NCT00187512Recruiting
Study of how HIV treatment changes outcomes over time
This is an observational study (not a new drug) that tracks how living with HIV can change over time in different treatment situations. It may help researchers understand long-term effects of the modern “protease inhibitor era” and improve future care.
San Francisco, CaliforniaAges 18 years+ - NCT05985642Recruiting
HIV treatment interruption study for long-term participants
This study looks at people with HIV who have already taken a break from their HIV medications (called an analytic treatment interruption, or ATI) as part of another study. It aims to understand how well the body can control the virus during longer breaks from treatment, up to 96 weeks.
San Francisco, CaliforniaAges 18 years+ - NCT07266831RecruitingPhase 2/Phase 3
New HIV treatment for people not yet on medication

PrEP on demand: a pilot study for men who have sex with men
This study tests a '2-1-1' on-demand PrEP strategy for cisgender men who have sex with men. It aims to see if taking PrEP only around the time of sex is safe and effective. If you are interested in starting or currently taking PrEP this way, you may be eligible.
San Francisco, CaliforniaAges 18 years+ - NCT07181486RecruitingPhase 1

What taking part in a hiv infections study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
