Brain-Spray chemo cocktail targets breast Cancer's deadliest spread

NCT ID NCT06543992

First seen Jul 21, 2026 · Last updated Jul 22, 2026 · Updated 1 time

Summary

This phase II trial tests whether injecting two chemotherapy drugs—thiotepa and methotrexate—directly into the spinal fluid can shrink or control breast cancer that has spread to the leptomeninges (the lining of the brain and spinal cord). Participants receive the drugs through an implanted Ommaya reservoir, a device that allows repeated access to the spinal fluid. The study will measure how many patients respond and how long the response lasts, while monitoring safety.

What this could mean

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

Active substance
a combination of thiotepa and methotrexate given directly into the spinal fluid via an Ommaya reservoir
What this could lead to
If successful, this could offer a new treatment option for breast cancer that has spread to the lining of the brain and spinal cord, potentially improving response rates and delaying disease progression.
What could go wrong
This is a small, early-phase trial with only 22 participants, so results may not apply broadly. The treatment involves direct injection into the spinal fluid, which carries risks like infection, nerve damage, or side effects from the chemotherapy drugs.
