A new study found that high doses of vitamin B3 (niacin) can help treat glioblastoma, a type of brain cancer. The treatment improved survival rates and reduced tumor growth.

Edward Waldner was feeling tired all the time and had trouble walking. He went to the hospital and discovered he had glioblastoma, an aggressive form of brain cancer. Doctors removed as much of the tumor as possible and gave him radiation therapy and chemotherapy. Despite these treatments, the cancer often comes back. Researchers at the University of Calgary are studying whether high doses of vitamin B3 (niacin) can improve outcomes when added to conventional glioblastoma treatment. Waldner was invited to participate in the clinical trial.

The study is being led by Drs. Gloria Roldan Urgoiti and Wee Yong, who developed a research program to determine whether niacin can restore the function of weakened immune cells and help them destroy tumor cells. The project began with mice and showed that niacin extended survival. This led the team to launch a Phase I and II clinical trial in people.

The clinical trial was designed to identify the highest safe dose and evaluate the potential benefits of controlled-release niacin when combined with standard chemotherapy and radiotherapy. Early findings from 24 patients exceeded expectations, with 82% having no signs of disease progression at six months.

Why It Matters

This study is important because glioblastoma is a deadly form of brain cancer that has not seen significant improvement in survival rates for 20 years. Any new treatment options can be life-changing for patients and their families.

Key Facts

• Glioblastoma is an aggressive form of brain cancer that often returns after initial treatment.
• Vitamin B3 (niacin) has shown promise in treating glioblastoma when added to conventional treatment.
• The study found that 82% of patients had no signs of disease progression at six months, a 28% improvement compared to previous studies.
