Summary

This is a pilot study to test the feasibility of implementing a strict classic ketogenic diet among a population of children with recurrent or progressive and refractory brain tumors. Eligible participants will be admitted to the neurosciences floor for 5 days to begin the ketogenic diet either orally, by gastrostomy tube or via nasogastric tube. During the inpatient stay, they will be extensively educated on the diet restrictions and rules. Participants will then continue on the diet at home returning about 17 times over the next 12 months. Daily logs will be kept tracking diet changes, bowel movements and urine ketones. Blood will be collected during the inpatient stay and at all visits for both standard clinical care and research testing.

Detailed description

Primary Objective is to determine the feasibility (safety and tolerability) of a strict classic ketogenic diet among a population of children with recurrent or progressive and refractory brain tumors. Secondary Objectives are: (1) to determine the objective response rate (complete response + partial response) to a strict classic ketogenic diet among children with recurrent or progressive and refractory brain tumor; (2) to estimate the time interval to tumor progression (Progression-Free Survival), time to treatment failure (Event-Free Survival), and time to death (Overall Survival) after initiation of a strict classic ketogenic diet among a group of pediatric patients with recurrent or progressive and refractory brain tumors; and (3) to describe and characterize tolerability and toxicities from a strict classic ketogenic diet among children with recurrent or progressive and refractory brain tumors. Exploratory Objective: Identify biomarker correlates, including MR spectroscopy and metabolites of tumor response to a strict classic ketogenic diet.

Conditions

• Recurrent Brain Tumor, Childhood
• Ketogenic Diet

Interventions

Type	Name	Description
OTHER	Strict Classic Ketogenic Diet	Diet is administered from a 2:1 to 4:1 ratio; this means 2 to 4 parts of fat to 1 part of both protein (calculated based on RDA and whatever remaining portion of carbohydrates.
