New drug aims to shrink HER2 breast tumors before surgery

NCT ID NCT07196774

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

Summary

This phase 3 trial is testing a new drug called SHR-A1811 against a standard chemotherapy combination for women with early-stage or locally advanced HER2-positive breast cancer. About 740 participants will receive either the new drug or standard treatment before surgery. The main goal is to see if the new drug leads to a complete disappearance of cancer in the breast tissue removed during surgery.

What this could mean

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

Active substance

SHR-A1811 (an antibody-drug conjugate)

What this could lead to

If successful, SHR-A1811 could offer a more targeted, potentially less toxic neoadjuvant option for HER2-positive breast cancer, improving the chance of a complete response before surgery.

What could go wrong

This is a phase 3 trial, but results are not yet known. SHR-A1811 may not outperform the standard regimen, and side effects could be similar or different. Long-term benefits like survival are still being followed.
