Brief Summary

The survival interval of patients with gliomas ranges between 12 to 15 months. Recent findings revealed that dietary interventions to reduce glucose and glycolytic pathways could have a therapeutic effect. Ketosis can be an effective therapy to extend the survival of patients with gliomas.

Outcome Measures

Primary Outcomes (1)

  • Overall survival

    Participants will be followed from date of randomization until the date of death from any cause, assessed up to 36 months.

Secondary Outcomes (4)

  • Changes in brain tumor size

    2 years, Baseline, 3, 6, 12, and 24 months

  • Time to progression

    2 years

  • Assessment of Quality of life using FACT-BR (version 4) survey

    Baseline, 3, 6, 12 months

  • Functional impairment will be assessed with the Karnofsky Performance Scale

    Baseline, 3, 6, 12 months

Study Arms (1)

Classic Ketogenic Diet

EXPERIMENTAL

Patients will adhere to a classic ketogenic diet for a period of 3 months with a possible extension depending on their compliance on the diet.

Other: CKD

Interventions

CKDOTHER

Patients/families will meet with the study dietician to discuss the CKD, ask questions, and plan clinic visits. Training will take place about diet, meal planning, and ketones/glucose monitoring. The dietitian will follow the patient throughout treatment. Patients will measure their urine ketosis with urine test strips and capillary ketones with blood ketone meters daily, and they will complete records from the start till the end of the study. Finally, they will meet with the dietitian at follow-up visits and on an as-needed basis.

Classic Ketogenic Diet
