About this study
The purpose of this study is to determine stool microbiome composition and biomarkers that are differentially abundant and those that are associated with response to treatment (eg, anticonvulsant drugs).
Read the detailed description
Recent research suggests that the intestinal microbiota plays a central role in human health, and may play a role in a variety of central nervous system disorders, including seizure susceptibility. The microbiota has been shown to be associated with changes in factors relevant to neurotransmission, including neurotransmitter signaling, synaptic protein expression, long-term potentiation, and myelination. In addition to the microbiota's potential role in general neurotransmission, research suggests that the gut microbiome may differ between patients with pharmaco resistant and pharmaco-sensitive epilepsies. In support of this idea, ketogenic diet has been used as an alternative treatment for those with pharmaco-resistant epilepsy and there are indications of possible direct interactions of anti-epileptic drugs (AEDs) with the intestinal microbiota.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Pharmaco-resistant epilepsy (PRE) | Pharmaco resistant patients are defined by seizures despite adequate dosing of ≥2 anticonvulsant drugs. | |
| Pharmaco-sensitive epilepsy (PSE) | Pharmaco-sensitive patients are defined by no seizures for 6 months. | |
| Sibling control | Sibling of the of the PRE study participants. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Pharmaco-sensitive (PSE) vs. pharmaco-resistant epilepsy (PRE) defined by no seizures for 6 months, and seizures despite adequate dosing of ≥2 anticonvulsant drugs, respectively
Bacterial species and metabolomic biomarkers that are associated with PRE/PSE are determined.
Measured: 24 months

The sponsor lists 6 inclusion and 8 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The record says: withdrawn, as of the sponsor's last update on 26 Feb 2021. 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.

The study was withdrawn before enrolling participants, so there are no results.
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?
Pharmaco-sensitive (PSE) vs. pharmaco-resistant epilepsy (PRE) defined by no seizures for 6 months, and seizures despite adequate dosing of ≥2 anticonvulsant drugs, respectively (time frame: 24 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 26 Feb 2021; AzTrials last refreshed its copy on 7 Nov 2026.
