What this research studies

This project tests whether adding the commonly used drug quetiapine to radiation can stop glioblastoma cells from changing into treatment-resistant cells and make radiation work longer. Researchers will first measure how the combination changes tumor cell metabolism, focusing on the mevalonate pathway, in lab and animal models. Next they will test the safety and effects of the combination in people with recurrent glioblastoma at UCLA. They will also study tumor-initiating cells to understand exactly how the treatment works and look for new weaknesses to target.

Who could benefit from this research

Good fit: Adults with recurrent glioblastoma who are medically able to receive radiation and participate in a clinical treatment study are the main candidates.

Not a fit: People with newly diagnosed glioblastoma, those who cannot tolerate quetiapine or radiation, or those with other serious health issues may not be eligible or likely to benefit.

Why it matters

Potential benefit: Could make radiation more effective against recurrent glioblastoma, potentially slowing tumor regrowth and improving survival or quality of life.

How similar studies have performed: Laboratory and animal studies and the team's preliminary data support this strategy, but clear benefits in people have not yet been proven.
