First seen Jun 27, 2026 · Last updated Jun 30, 2026 · Updated 2 times

Summary

This early-stage trial tests an investigational cancer vaccine called ITI-5000 in 60 people with stage II-III triple-negative breast cancer who have finished standard treatment. The vaccine uses self-amplifying RNA to teach the immune system to attack cancer cells. The study first finds a safe dose of the vaccine alone, then tests it combined with the immunotherapy drug pembrolizumab.

What this could mean

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

Active substance

ITI-5000 (self-amplifying RNA vaccine) and pembrolizumab

What this could lead to

If successful, this could lead to a new treatment option to prevent triple-negative breast cancer from coming back after standard therapy.

What could go wrong

This is a very early Phase 1 trial with only 60 participants, so it is too soon to know if the vaccine works. There may be side effects from the vaccine or the combination with pembrolizumab.
