New two-drug combo aims to wipe out HER2 breast cancer before surgery

NCT ID NCT06747338

First seen Jul 07, 2026 · Last updated Jul 08, 2026 · Updated 1 time

Summary

This phase 3 trial compares a new drug combination (KN026 plus HB1801, with or without carboplatin) against the standard treatment (trastuzumab, pertuzumab, and docetaxel, with or without carboplatin) in people with early or locally advanced HER2-positive breast cancer. The goal is to see if the new combination works better at eliminating cancer before surgery. About 520 participants will be enrolled across multiple centers.

What this could mean

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

Active substance
KN026 (a bispecific antibody) combined with HB1801 (a chemotherapy drug)
What this could lead to
If successful, this could offer a more effective pre-surgery treatment option for people with HER2-positive breast cancer, potentially improving the chance of eliminating all cancer before surgery.
What could go wrong
This is an early-phase comparison; the new combination may not be more effective than the current standard and could have unexpected side effects. Results are not yet known.
