Ketogenic Diet + Radiation & Chemotherapy for Glioblastoma
What You Need to Know Before You Apply
What is the purpose of this trial?
Enrolled subjects will be placed on a 16-week ketogenic diet (subject specific as prescribed by RD) while receiving standard of care cancer treatment (Radiation + Temozolomide). Study dietitians will create personalized meal plans for each patient with the goal of achieving and maintaining protocol defined metabolic ketosis. Subjects will be monitored for safety, nutrition, quality of life, and standard of care tumor assessments over the course of the study.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications. However, patients on low and managed doses of steroids are allowed, and those on high doses are excluded. It's best to discuss your specific medications with the trial team.
Is the combination of a ketogenic diet, radiation, and temozolomide safe for treating glioblastoma?
Temozolomide, when used with radiation, is generally considered safe but can cause blood-related side effects like myelosuppression (reduced bone marrow activity) and, rarely, more severe conditions like aplastic anemia. These side effects are uncommon, but they can lead to treatment delays or discontinuation.12345
What makes the ketogenic diet combined with radiation and chemotherapy unique for treating glioblastoma?
This treatment is unique because it combines a ketogenic diet, which lowers blood sugar and increases ketones, with standard radiation and chemotherapy. The ketogenic diet may help improve outcomes by targeting the energy metabolism of brain tumors, potentially enhancing the effectiveness of traditional treatments.678910

Are You a Good Fit for This Trial?
Adults over 18 with newly diagnosed glioblastoma can join this trial if they're being treated at Cedars-Sinai Medical Center or elsewhere for chemotherapy/radiation. They must be able to follow a ketogenic diet, have a BMI of ≥22, and be on low doses of steroids. Excluded are those with certain medical conditions, high steroid doses, vegan/vegetarian diets, allergies to specific materials used in the study tools, and incompatible implants.Inclusion Criteria
