Summary

This early-phase trial tests whether letrozole, a drug normally used for breast cancer, can reach and concentrate in recurrent high-grade gliomas (aggressive brain tumors). About 39 adults will take letrozole pills daily along with standard temozolomide chemotherapy. Researchers will measure how much letrozole gets into the tumor and track side effects and survival.

What this could mean

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

Active substance

Letrozole (Femara) and Temozolomide (Temodar)

What this could lead to

If it works, this could point toward a new way to treat recurrent high-grade gliomas by combining letrozole with standard chemotherapy.

What could go wrong

This is a very early, small trial (39 people) focused on drug levels and safety, not yet on effectiveness. The drug may not reach tumors enough or may cause side effects.
