Study summary

According to the World Health Organization, more than 50 million people have epilepsy. Among them, nearly 80% of epileptic patients live in developing countries and 75% of them do not have access to treatment. The ketogenic diet (KD) has been shown as an effective alternative for patients with drug-resistant epilepsy. Although it has been studied by few studies in Asia, no such studies have been conducted in Vietnam. The purpose of this study was to verify the feasibility, tolerability, and efficacy of the KD in children with refractory epilepsies followed at a pediatric center in South Vietnam.

Read the detailed description

Children with drug-resistant epilepsy followed at Children's Hospital No.2, Viet Nam treated by KD were included in a prospective study from June 2019 to October 2021. Side-effects, retention rate, number, and duration of seizures were recorded after 1, 3, 6, 9, and 12 months of KD. Patients were considered as responders when a 50% seizure frequency was reached. Tolerance and acceptability of the KD were closely monitored.

Study arms

  • Experimental
    The feasibility of the ketogenic diet

    The purpose of this study was to verify the feasibility of the ketogenic diet in children with refractory epilepsies followed at a pediatric center in South Vietnam. The patient was considered feasible if he (or she) did not have the contra-indication for the ketogenic diet

    Dietary Supplement: Ketogenic diet

  • Experimental
    the tolerability of the ketogenic diet

    The purpose of this study was to verify the tolerability of the ketogenic diet in children with refractory epilepsies followed at a pediatric center in South Vietnam. The patient was considered tolerant if he (or she) did not have any side effects caused by the ketogenic diet

    Dietary Supplement: Ketogenic diet

  • Experimental
    the efficacy of the ketogenic diet

    The purpose of this study was to verify the efficacy of the ketogenic diet in children with refractory epilepsies followed at a pediatric center in South Vietnam. Patients were considered responders when a 50% seizure frequency was reached.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jun 2019 to primary completion in Oct 2021, 28 months.

Of 94 non-industry interventional studies with no phase under Drug Resistant Epilepsy, half reached primary completion within 34 months of starting (the median), counting those still running; a quarter within 20 and three quarters within 75. This study's 28 months is below that.

Counting every sponsor, half of 106 studies reached it within 34 months; a quarter within 21 and three quarters within 56.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 26, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
