Testing a ketogenic diet or ketone drink in people with glioma that came back
Original title: GLAD-KE GLioma Biomarker and Safety Assessment During Dietary Ketone Elevation Subtitle: A Surgical Biomarker Discovery Study of Ketogenic Therapy in Recurrent Glioma
How far along is this research?
This is a trial that is enrolling or has been updated. It is not a finding yet.
No phase is listed, and this is an early study checking safety and whether people can do it.
Status: Not yet recruiting. It has not opened yet. Ask your care team to watch for it if it looks like a fit.

The short version
This study looks at whether a high fat diet or a ketone supplement is safe and doable before brain surgery.
Who this trial is for. This trial is for adults with a glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary that has come back and who are already having surgery their doctors say they need. It tests a ketogenic diet, or a short course of a ketone supplement, before that surgery.
Where it stands. This trial has not reported results. It is looking at whether the diet or the supplement is safe and whether people can stick with it. The answer is not in yet.
What this means, and what it doesn't
What it could mean: If your tumor has come back and surgery is already planned, this is one study you could ask your care team about. They can tell you if it fits your situation. Right now it tells us nothing about whether the diet helps a tumor.
What it doesn't mean: This does not mean a ketogenic diet or a ketone supplement treats brain tumors. A trial is a test, not a proven treatment. Joining one is not a promise that you will be helped, and it is not a promise of a cure. Do not change how you eat during cancer treatment without talking to your care team first.
