Brief summary

The goal of the present study is to evaluate efficacy, safety and tolerability of 4:1 ketogenic diet administered adjunctively to standard radiation and temozolomide chemotherapy in patients with GBM in a prospective, randomized open label study.

Detailed description

Primary aims of the study will be to 1) To evaluate efficacy of ketogenic diet as adjunctive treatment of radiation treatment in glioblastoma multiforme. 2) To evaluate the safety of ketogenic diet as adjunctive treatment of radiation treatment in glioblastoma multiforme. Secondary aim will be to evaluate tolerability of ketogenic diet as adjunctive treatment of radiation treatment in glioblastoma multiforme. Participants will be seen at one, 2 weeks, and 4 weeks after KG diet initiation, and then monthly until month 6 after diet initiation, then every 2 months until 2 years after treatment initiation or death, then every 3 months until 3 years after treatment initiation or death. KD treatment will last for 6 months or until exit criteria are met, whichever comes first. Exit criteria are the primary outcome measures, the first of either (a) MRI tumor progression or (b) death. Secondary outcome measures will include treatment compliance, hunger scale scores, fasting serum glucose and BOH levels and occurrence of adverse events. Patients with documented tumor progression will receive standard care for progressive GBM as directed by their treating oncologist, independent of the study.

Interventions

OTHERKetogenic Diet

Treatment will consist of ketogenic diet. KD will consist of 4:1 \[fat\] : \[protein+carbohydrate\] weight ratio with 1600 kcal restriction.

Participants with GBM treated with radiation and temozolomide after surgical debulking treatment. The subjects will be taken standard diet in a 1:1 ratio. Diet will be started at the time of initiation of radiation treatment.

Inclusion criteria

1. Age 18-65 2. Ability and willingness to signed informed consent form 3. Astrocytoma grade 4 (glioblastoma multiforme, GBM, histologically confirmed, WHO criteria) 4. Documented surgical resection/debulking 5. Measurable contrast-enhancing GBM by MRI imaging ≤ two weeks before screening or prior to surgery if done ≤ 2 months before 6. Karnovsky Performance Score of 70 or more

Exclusion criteria

1. Acute intracranial or intratumoral hemorrhage \> Grade 1 either by MRI or CT scan ≤2 weeks of screening. (Subjects with resolving hemorrhage changes, punctate hemorrhage, or hemosiderin may enter the study) 2. Prior treatment with any of the following: (a) small-molecule kinase inhibitor; (b) non-cytotoxic hormonal agent; (c) KD ≤6 months of enrollment 3. Planned continued use of glucocorticoids 4. Anticoagulation treatment with ≥ 1 mg/day coumadin ≤ 7 days prior to screening (low-dose \[≤ 1 mg/day\] coumadin, heparin, and low-molecular-weight heparin are permitted) 5. Any systemic illness or unstable medical condition that might pose additional risk, including: cardiac, unstable metabolic or endocrine disturbances, renal or liver disease, past history of renal calculi, hyperuricemia, hypercalcemia, mitochondrial disease, known disorder of fatty acid metabolism, porphyria, carnitine deficiency and pancreatitis 6. History of non-glioma malignancy other than: 1. Surgically excised non-melanoma skin cancer or in situ carcinoma of the cervix 2. A malignancy diagnosed ≥2 years ago if the subject has had no evidence of disease for 2 years prior to screening 7. History of uncontrolled hyperlipidemia 8. Active drug or alcohol dependence or any other factors that, in the opinion of the site investigators would interfere with adherence to study requirements 9. History of human immunodeficiency virus, or hepatitis C 10. Failure to recover from \<CTCAE grade 2 toxicities related to prior therapy 11. Pregnancy or breastfeeding 12. Use of any investigational drug within 1 months of enrollment 13. Inability or unwillingness of subject to give written informed consent

Design outcomes

Primary

MeasureTime frameDescription
The incidence of treatment-emergent adverse events during treatment6 monthsIncidence of treatment-emergent adverse events changes in laboratory evaluations, changes in physical examination findings will be compared between the KD and control treatment groups
survival time6 monthsWe hope to achieve a substantial difference in both survival time and time to recurrence between the KD and non-KD treatment groups. Survival time of 3 years from treatment initiation and tumor progression-free time of 2.5 years from treatment initiation would be extraordinary compared to historical data.
time to radiological (MRI) tumor progression6 monthsMRI outcome will be assessed by the radiographic assessment in neuro-oncology criteria based on contrast-enhanced cranial MRI scans evaluating measureable disease, measured as the sum of products of perpendicular diameters (bi-dimensional measurements) of all measurable enhancing lesions and non-measurable disease.

Secondary

MeasureTime frameDescription
Tolerability of ketogenic diet: Rate of early discontinuation of subjects from the diet because of intolerability, defined as unwillingness by the subject to continue with the diet because of possible diet related side effects6 monthsRate of early discontinuation of subjects from the diet because of intolerability, defined as unwillingness by the subject to continue with the diet because of possible diet related side effects will be evaluated using descriptive statistics
