Could a common vitamin boost brain cancer treatment?

NCT ID NCT04677049

First seen Jun 27, 2026 ยท Last updated Jun 27, 2026

Summary

This study tests whether adding niacin (vitamin B3) to standard treatment (radiation and chemotherapy) can help people with newly diagnosed glioblastoma, an aggressive brain cancer. The trial has two phases: first, finding a safe dose of niacin, and second, checking if it improves survival at 6 months. About 59 adults aged 18-75 are being enrolled, but the trial is currently on hold.

What this could mean

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

Active substance
Niacin (vitamin B3) controlled-release tablet
What this could lead to
If it works, this could point toward a way to improve survival for people with glioblastoma by adding a simple vitamin to standard therapy.
What could go wrong
This is an early-phase trial (phase I-II) with only 59 participants, so results may not apply broadly. The trial is currently suspended, and adding niacin may not improve outcomes or could cause side effects.
