  Purpose
The investigators are undertaking the first European Randomised Controlled Trial (RCT) for epilepsy surgery in children with FCD type II, to prospectively evaluate the role of the KD prior to surgery in improving seizure outcome. The investigators will evaluate the role of KD as a disease-modifying treatment to achieve seizure control and improve neurodevelopment and quality of life. Children age 3 - 15 years with pharmacoresistant epilepsy believed to be the result of focal cortical dysplasia type II, considered to be surgically treatable, will be randomised to either receive 6m treatment presurgery with a ketogenic diet, or to proceed direct to surgery (no pretreatment). Primary outcome will be the time to achieve a period of 6 months of seizure freedom from the date of randomisation. Tissue resected at surgery will also be evaluated with regard to the degree of any methylation of DNA.

Primary Outcome Measures:
  • Time to 6 month remission [ Time Frame: Month 33 ]
    the time to achieve a period of 6 months of seizure freedom from the date of randomisation pretreated KD group vs non pretreated group


Secondary Outcome Measures:
  • Time to first seizure from date of randomisation; [ Time Frame: 33 months ]
    The time to first seizure from date of randomisation, KD pretreated vs non pretreated group

  • Time to 12 month remission after randomisation [ Time Frame: 45 months ]
    Time to 12 month remission from seizures from date of randomisation, KD pretreated vs non pretreated group

  • Time to 24 month remission after randomisation (if enough time for follow-up is available) [ Time Frame: 45 months ]
    Time to 24 months remission from seizures from date of randomisation, KD pretreated vs non pretreated group

  • Quality of life at 12 (and at 24 months if enough time for follow-up is available) [ Time Frame: 45 months ]
    As determined by KINDL questionnaire, comparison of pretreated vs non pretreated group

  • Adaptive behaviour assessment at 12 months, after randomisation (and at 24 months if enough time for follow-up is available); [ Time Frame: 45 months ]
    Comparison of neurodevelopmental change between pretreated and non pretreated KD group, as measured by Vineland adaptive behaviour scales

  • Methylation changes in tissue (DNA) from children pre-treated with the ketogenic diet compared to those not pretreated [ Time Frame: 60 months ]
    As measured from tissue resected at surgery

  • Changes in peripheral DNA (blood platelets) following treatment with the KD [ Time Frame: 60 months ]
    As measured from samples taken following the KD

  • Proportion of immediate AEs following resective surgery (i.e. surgical complications within 30 days) [ Time Frame: 45 months ]
    As compared between groups, group pre-treated with KD compared to those without

  • Compare the general AE occurrence [ Time Frame: 60 months ]
    As compared between groups, group pre-treated with KD compared to those without

Primary Completion Date: July 26, 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: A: Classical ketogenic diet
The KD is a high fat, low carbohydrate, low protein diet designed to mimic the effects of fasting on the body. It will be administered by calculation as per local standardised classical KD protocol with utilisation of long chain fat in a ratio of 2:1 to 4:1 carbohydrate and protein.
Dietary Supplement: Classical ketogenic diet
A high fat low carbohydrate, low protein diet.
No Intervention: B: No pretreatment
Following the decision to proceed to surgery, if randomised to this arm a date will be given for surgery as per routine clinical practice. No KD pre-treatment will be undertaken.
