About this study

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.

Read the 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Ketogenic DietOther

    Also called KGD

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

  • Standardized DietOther

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: 6 months

  2. 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.

    Measured: 6 months

  3. 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

    Measured: 6 months

Secondary outcomes (1)
  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

    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 will be evaluated using descriptive statistics

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ketogenic Diet and Standardized Diet in people with Glioblastoma Multiforme of Brain, run by Mid-Atlantic Epilepsy and Sleep Center, LLC at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

survival time (time frame: 6 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02302235, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Aug 2022.
