Can a drug combo outsmart a tough breast cancer subtype?

NCT ID NCT07760844

First seen Aug 12, 2026 · Last updated Aug 13, 2026 · Updated 1 time

Summary

This phase III trial is testing whether adding everolimus to trastuzumab rezetecan helps people with a specific subtype of triple-negative breast cancer (called luminal androgen receptor) live longer without their disease progressing. The study enrolls adults with advanced or metastatic cancer that has not responded well to prior treatments. Participants receive either the antibody-drug conjugate alone or in combination with everolimus, and researchers compare how long the cancer stays controlled.

What this could mean

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

Active substance
trastuzumab rezetecan (an antibody-drug conjugate targeting HER2) with or without everolimus
What this could lead to
If adding everolimus improves progression-free survival, this could become a new standard treatment for this hard-to-treat breast cancer subtype.
What could go wrong
This is an early-phase trial with a relatively small number of participants, and the combination may not prove more effective than the single drug. Side effects from the combination could also limit its use.
