About this study

Official title: Clinical Study Evaluating the Safety and Efficacy of N-acetyl Cysteine in Children With Drug-Resistant Epilepsy

This study aims at investigating the possible efficacy and safety of N-acetyl cysteine as adjuvant therapy in the treatment of drug-resistant epilepsy

Read the detailed description

N-acetyl-cysteine (NAC), a glutathione precursor, is proven to activate the nuclear factor E2-related factor 2( Nrf2) in mouse models of status epilepticus, thus inhibiting high mobility group box 1 (HMGB1) cytoplasmic translocation in the hippocampal neural and glial cells and preventing the linkage between oxidative stress and neuroinflammation for which the redox-sensitive protein HMGB1 is central. Therefore,It may be useful as an adjuvant in treating various medical conditions, especially neuropsychiatry.

What participants receive

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

  • N-acetyl cysteineDrug

    Also called NAC

    10 mg/kg of N-acetyl cysteine capsules together with their standard antiepileptic drug for 6 months.

  • PlaceboDrug

    Also called control

    15 patients will receive standard antiepileptic drug plus placebo capsules for 6 months.

  • NAcDrug

    40 mg/kg of N-acetyl cysteine capsules together with their standard antiepileptic drug for 6 months.

What is being measured

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

  1. effectivness of acetyl cysteine for controlling epileptic seizures in children with drug resistant epilepsy.

    effectivness can be defined as more than 50% reduction in number of seizures.

    Measured: 6 months

Secondary outcomes (1)
  1. analyze the differences of improvement of quality of life via using Helth related quality of life questionnaire

    Caregivers will complete the Quality of Life in Childhood Epilepsy (QOLCE) Scale(QOLCE-55).The QOLCE-55 sections' included the following domains: cognitive, emotional, social, and physical functioning Each item is on a 6-point Likert scale and includes anchors that are subjectively rated based on perceived QOL (e.g., 1 = very often, 2 = fairly often, 3 = sometimes, 4 = almost never, 5 = never, 6 = non-applicable).

    Caregivers completed the Quality of Life in Childhood Epilepsy (QOLCE) Scale.17

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing N-acetyl cysteine and NAc in people with Drug Resistant Epilepsy, run by Tanta University at 1 site in Egypt.

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 3 inclusion and 3 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 1 Jul 2025. 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 Egypt. 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. Some participants in this study may receive a placebo. 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?

effectivness of acetyl cysteine for controlling epileptic seizures in children with drug resistant epilepsy. (time frame: 6 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 1 Jul 2025.
