New combo attack on breast cancer brain metastases: immunotherapy plus chemo and radiation

NCT ID NCT06839560

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This phase 2 trial tests whether adding a PD-L1 antibody (adebrelimab) to a three-drug chemotherapy regimen (vinorelbine, cyclophosphamide, capecitabine) and either early or delayed radiotherapy can help control brain tumors in people with advanced HER2-negative breast cancer. About 102 participants will be randomly assigned to receive the combination with concurrent or delayed radiation. The main goal is to see how long the brain tumors stay under control.

What this could mean

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

Active substance

Adebrelimab (PD-L1 monoclonal antibody) plus vinorelbine, cyclophosphamide, and capecitabine (VEX metronomic chemotherapy) with radiotherapy

What this could lead to

If successful, this combination could offer a new treatment option for people with HER2-negative breast cancer that has spread to the brain, potentially improving control of brain tumors.

What could go wrong

This is an early-phase study with only 102 participants, so results may not apply to everyone. The combination of drugs and radiation may cause significant side effects, and it is not yet known if it works better than standard care.
