Stiripentol for the Treatment of Refractory Status Epilepticus

August 5, 2024 updated by: Leona Möller, University Hospital Marburg
The investigators retrospectively analyzed all patients who were admitted to the Department of Neurology at Marburg University Hospital between 2013 and 2023 with a diagnosis of (super)-refractory status epilepticus and who received additional treatment of SE with STP. All patients who received STP during the SE were included, regardless of previous medication.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The investigators retrospectively analyzed all patients who were admitted to the Department of Neurology, University Hospital Marburg, Germany, between 2013 and 2023 with a diagnosis of status epilepticus, who received additional treatment of SE with STP. They were able to identify 25 patients who received STP as add on therapy. All these patients suffered from RSE or SRSE. Since there was no SOP or treatment algorithm available, they have listed the individual treatment regimens in Table 2. 5 of these patients were previously published in a case series (Strzelczyk et al. 2015).

Treatment success was defined as continuous interruption of the SE. Descriptive statistics are reported as absolute numbers and percentages, mean ± standard deviation (SD) or median ± median absolute deviation.

The study was approved by the local IRB.

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Cessation of Status epilepticus
Time Frame: time to cessation of SE, normally during the first days of admission, up to one week
time to cessation of SE, normally during the first days of admission, up to one week
Number of participants with cessation of SE by STP
Time Frame: up to one week
up to one week
Median dose of STP
Time Frame: From date of first admission until the date of first documented improvement of status epilepticus or severe sideeffects or termination due to lack of effect or date of death from any cause, whichever came first, assessed up to 12 months
From date of first admission until the date of first documented improvement of status epilepticus or severe sideeffects or termination due to lack of effect or date of death from any cause, whichever came first, assessed up to 12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Treatment in combination with other anti-seizure medication
Time Frame: From date of first admission until the date of first documented improvement of status epilepticus or severe sideeffects or termination due to lack of effect or date of death from any cause, whichever came first, assessed up to 12 months
From date of first admission until the date of first documented improvement of status epilepticus or severe sideeffects or termination due to lack of effect or date of death from any cause, whichever came first, assessed up to 12 months
Individualised order of the anti-seizure medication administered
Time Frame: From date of first admission until the date of first documented improvement of status epilepticus or severe sideeffects or termination due to lack of effect or date of death from any cause, whichever came first, assessed up to 12 months
From date of first admission until the date of first documented improvement of status epilepticus or severe sideeffects or termination due to lack of effect or date of death from any cause, whichever came first, assessed up to 12 months

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2013

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
December 31, 2023

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
