Pilot Study of a Metabolic Nutritional Therapy for the Management of Primary Brain Tumors

Adult subjects with newly diagnosed glioblastoma will be referred to the study. Residual tumor size will be determined using MRI imaging. Subjects will be placed on ERKD while they are being treated with radiation therapy and standard of care chemotherapy. After completion of radiation therapy, tumor size will be determined using MRI. If the tumor has decreased in size or remained the same (stable disease), the subjects will be continued on the ERKD for an additional 6 weeks. Total calories consumed by each subject will be targeted to 20 to 25 kcal/kg/day. If the tumor has decreased in size or the size has remained the same then subjects will be continued on the ERKD for as additional 6 weeks and a repeat MRI will be obtained.
