NCT02302235

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.

Outcome Measures

Primary Outcomes (3)

  • survival time

    We 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.

    6 months

  • time to radiological (MRI) tumor progression

    MRI 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.

    6 months

  • The incidence of treatment-emergent adverse events during treatment

    Incidence of treatment-emergent adverse events changes in laboratory evaluations, changes in physical examination findings will be compared between the KD and control treatment groups

    6 months

Secondary Outcomes (1)

  • 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 effects

    6 months

Study Arms (2)

Ketogenic Diet

ACTIVE COMPARATOR

Treatment will consist of ketogenic diet. KGD will consist of 4:1 \[fat\] : \[protein+carbohydrate\] weight ratio with 1600 kcal restriction. Diet will be started at the time of initiation of radiation treatment.

Other: Standardized Diet

Standardized diet

OTHER

The subjects will be taken standard diet in a 1:1 ratio.

Other: Ketogenic Diet

Interventions

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

Also known as: KGD
Standardized diet

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.

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

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

You may not qualify if:

  • 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)
  • Prior treatment with any of the following: (a) small-molecule kinase inhibitor; (b) non-cytotoxic hormonal agent; (c) KD ≤6 months of enrollment
  • Planned continued use of glucocorticoids
  • 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)
  • 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
  • History of non-glioma malignancy other than:
  • Surgically excised non-melanoma skin cancer or in situ carcinoma of the cervix
  • A malignancy diagnosed ≥2 years ago if the subject has had no evidence of disease for 2 years prior to screening
  • History of uncontrolled hyperlipidemia
  • Active drug or alcohol dependence or any other factors that, in the opinion of the site investigators would interfere with adherence to study requirements
  • History of human immunodeficiency virus, or hepatitis C
  • Failure to recover from \<CTCAE grade 2 toxicities related to prior therapy
  • Pregnancy or breastfeeding
  • Use of any investigational drug within 1 months of enrollment
  • Inability or unwillingness of subject to give written informed consent
