Can a Two-Day diet change help fight brain cancer?
NCT ID NCT07553520
First seen Apr 29, 2026 · Last updated Jun 23, 2026 · Updated 12 times
Summary
This pilot study aimed to see if a diet low in two specific nutrients (cysteine and methionine) could affect metabolism in patients with recurrent gliomas. Up to 30 participants were to be randomly assigned to either a normal diet or the special diet for 2, 4, or 7 days before standard treatment. Researchers planned to measure changes in blood, urine, and tumor samples to understand how the diet impacts cancer cells. However, the study was withdrawn before enrolling any participants.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Cysteine/methionine deprivation (CMD) diet
What this could lead to
If successful, this could point toward a dietary approach to help manage brain tumors by altering cancer cell metabolism.
What could go wrong
This is a very early pilot study with no participants enrolled, so results are uncertain. The diet is short-term and may not affect tumor growth or survival.
