Could antibody infusions help prevent HIV? new trial begins

NCT ID NCT06812494

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 2 trial is testing whether a combination of three lab-made antibodies is safe and tolerable in 200 healthy adults without HIV. Participants receive one or more IV infusions of the antibodies and are followed for 18 months. The goal is to see if this approach could eventually be used to prevent or control HIV infection.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

three lab-made antibodies (VRC07-523LS, PGT121.414.LS, PGDM1400LS) given by IV infusion

What this could lead to

If successful, this could point toward a new way to prevent or control HIV using infusions of antibodies instead of daily pills.

What could go wrong

This is an early phase 2 trial focused on safety, so it is not yet testing whether the antibodies actually prevent HIV. The antibodies may not work as hoped, and side effects are possible.
