Using vitamin C to enhance treatment for brain cancer

Official title: Redox manipulation of iron to improve glioblastoma therapy: A phase 1 trial

Funded at University of Iowa · NIH-10842278 · Data updated 2026-11-12

This study is looking at whether high-dose vitamin C given through an IV can make standard treatments for glioblastoma, a tough type of brain cancer, work better by helping to damage the cancer cells more effectively.

Who could benefit from this research

Could help

Ideal candidates for this research are patients diagnosed with glioblastoma who are undergoing standard treatment and have specific tumor characteristics.

Less likely to help

Patients with glioblastoma who do not meet the specific tumor criteria or those who are not receiving standard treatment may not benefit from this research.

What this research studies

This research investigates the use of pharmacological ascorbate, or high-dose intravenous vitamin C, in combination with standard therapies for glioblastoma, a highly aggressive brain cancer. The approach focuses on how vitamin C can enhance the effectiveness of radiation and chemotherapy by altering the metabolism of iron in tumor cells, leading to increased production of harmful reactive oxygen species that can damage cancer cells. Patients will be monitored for safety and treatment outcomes as they receive this combined therapy.

Why it matters

Potential benefit: If successful, this research could improve survival rates and treatment outcomes for patients with glioblastoma.

How similar studies have gone: Previous trials have shown promising results with similar approaches, indicating potential for significant advancements in glioblastoma treatment.
