Smartwatch and app join fight against metastatic breast cancer

NCT ID NCT07371585

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests the drug trastuzumab deruxtecan (T-DXd) as a first treatment for people with HER2-positive breast cancer that has spread. About 300 participants will take the drug and use digital tools like a smartwatch and pulse oximeter to catch side effects early. The goal is to see if this approach helps control the cancer and improves quality of life.

What this could mean

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

Active substance

trastuzumab deruxtecan (T-DXd)

What this could lead to

If successful, this could confirm T-DXd as an effective first-line treatment for HER2-positive metastatic breast cancer, potentially improving how long patients live without needing other therapies.

What could go wrong

This is a Phase 2, single-arm study without a comparison group, so results may not prove superiority over current standards. Side effects like lung inflammation (ILD) are a known risk with T-DXd.
