New personalized vaccine trial aims to boost immune attack on aggressive breast cancer

NCT ID NCT07300475

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

Summary

This early-phase trial is testing whether a personalized cancer vaccine, made from a patient's own tumor, can safely boost the immune system's ability to fight triple negative breast cancer. About 30 newly diagnosed patients will receive the vaccine along with standard chemotherapy and immunotherapy, with some also getting an additional immune-boosting drug called AB248. The main goals are to check safety, see if the vaccine can be made in time, and measure immune responses.

What this could mean

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

Active substance
personalized cancer vaccine (PCV) with or without AB248 (CD8-selective IL-2 mutein fusion protein)
What this could lead to
If successful, this could lead to a more effective treatment approach for triple negative breast cancer by training the immune system to fight the cancer more precisely.
What could go wrong
This is an early Phase 1 trial with only 30 participants, so it is primarily testing safety and feasibility. The personalized vaccine may not trigger a strong enough immune response, and side effects from the combination therapy are unknown.
