Cancer-Fighting virus trial for breast cancer pulled before it began

NCT ID NCT07150767

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

Summary

This early-stage trial aimed to test a new virus-based drug called BioTTT001, injected directly into tumors, alongside standard pre-surgery treatment for women with locally advanced breast cancer. The goal was to see if the combination was safe and could shrink tumors. However, the study was withdrawn before enrolling any participants, so no results are available.

What this could mean

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

Active substance
BioTTT001 (a modified virus injected into tumors to stimulate the immune system)
What this could lead to
If successful, this approach could offer a new way to shrink tumors before surgery for locally advanced breast cancer.
What could go wrong
The trial was withdrawn before any patients enrolled, so no data exists. Early-phase virus therapies can cause flu-like side effects and may not work for everyone.
