NCT ID NCT06433609

First seen Jul 14, 2026 · Last updated Jul 15, 2026 · Updated 1 time

Summary

This phase II trial tests whether combining three experimental antibody-drug conjugates (SHR-A1811, SHR-A1921, and SHR-A2102) with the immunotherapy drug adebrelimab can shrink tumors in people with HER2-negative advanced breast cancer. Participants must have already tried at least one prior systemic therapy. The study measures how many patients respond to treatment and how long the benefit lasts.

Active substance
three experimental antibody-drug conjugates (SHR-A1811, SHR-A1921, SHR-A2102) combined with an immunotherapy drug called adebrelimab
What this could lead to
If successful, this combination could offer a new treatment option for people with HER2-negative advanced breast cancer who have run out of standard therapies.
