Stopping radiation resistance in glioblastoma

Project 2: Overcoming GBM RT-resistance

NIH-funded research University of Michigan at Ann Arbor · NIH-11180416

This project gives a brain-penetrant drug that blocks purine metabolism together with standard radiation and temozolomide to people with glioblastoma to try to make radiation work better.

What this research studies

If you join, you would receive an FDA-approved, brain-penetrant drug that lowers purine metabolism alongside standard radiation and temozolomide. Researchers will collect tumor samples and use lab models to study how nearby non-cancer cells promote tumor metabolism and radiation resistance. They will measure purine pathway activity in patient tumors to identify who may have the resistance mechanism. The project includes a Phase 1B clinical trial to test safety and look for early signs of benefit.

Who could benefit from this research

Good fit: People with newly diagnosed glioblastoma who are scheduled for standard radiation plus temozolomide and who can safely take the purine metabolism inhibitor are the likely candidates.

Not a fit: Patients whose tumors do not depend on purine metabolism, who cannot tolerate the study drug or radiation, or who have medical issues preventing protocol treatment may not benefit.

Why it matters

Potential benefit: If successful, this approach could make radiation more effective against glioblastoma and help delay or prevent tumor recurrence, potentially improving survival and outcomes.

How similar studies have performed: Preclinical studies support targeting purine metabolism and metabolic therapies have shown promise, but combining a brain-penetrant purine inhibitor with radiation in patients is a new clinical approach.
