NCT ID NCT06430905
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-stage trial tests two experimental vaccines, HB-502 and HB-501, designed to teach the immune system to recognize and attack HIV. The study includes 30 people with HIV who are already on suppressive antiretroviral therapy. Participants receive injections every 8 weeks for 24 weeks, followed by 24 weeks of monitoring to check safety and immune response.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
HB-502 and HB-501 (arenavirus-based vector therapy)
What this could lead to
If successful, this could point toward a way to control HIV without lifelong daily medication, potentially allowing people to stop antiretroviral therapy.
What could go wrong
This is a very early phase 1 trial with only 30 participants, focused on safety. It may not show strong immune responses, and the study has already been terminated, so results may be limited.
