The short version
This study is testing whether a keto diet helps people with a new glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary live longer than standard diet advice does.
Who this trial is for. This trial is for people with newly diagnosed glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary who are getting standard treatment for their tumor. It plans to include 170 patients and compares a keto diet, followed for 18 weeks with trained research dietitians, against standard anti-cancer diet guidance.
Where it stands. This trial has not reported results. It is set up to see whether the keto diet helps people live longer than the standard diet guidance does. Daily ketone and glucose levels are recorded to track how well people stick to the keto diet. The answer is not in yet.
What this means, and what it doesn't
What it could mean: If you have a new glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary diagnosis, this is one thing you could ask your care team about. The diet in this trial is guided by trained dietitians, not done on your own. Your team can help you think through whether a trial makes sense for you.
What it doesn't mean: This does not mean a keto diet is a proven treatment for glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary. A trial is a test. Being in one is not a guarantee that it will help you. It is not a promise of a cure.
