Seizure Treatment in Glioma

Study Purpose

Currently, treatment with a specific anti-epileptic drug mainly depends on the physicians' preference, as there are no studies supporting the use of one specific anticonvulsant in glioma patients. The overall aim of this randomized controlled trial is to directly compare the effectiveness of treatment with levetiracetam or valproic acid in glioma patients with a first seizure.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	18 Years and Over
Gender	All

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT03048084
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 4
Lead Sponsor The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.	Leiden University Medical Center

Conditions The disease, disorder, syndrome, illness, or injury that is being studied.	Glioma

Additional Details

Currently, treatment of glioma patients with a specific anti-epileptic drug (AED) mainly depends on the physicians' preference, as there is no robust evidence from randomized controlled trials supporting the use of one specific anticonvulsant above the other in glioma patients. Levetiracetam and valproic acid are the most commonly used AEDs in glioma patients. Both drugs are used for the treatment of seizures, have similar toxicity profiles and are non-enzyme inducing AEDs, therefore not interfering with chemotherapeutic drugs. However, it is not known whether one drug is more effective than the other in reducing seizures.

Arms & Interventions

Arms

Active Comparator: Levetiracetam

Patients in this treatment arm will receive levetiracetam monotherapy. The dosage depends on the specific treatment step, as indicated in the protocol. In step 1, patients will receive 2x500 mg/d levetiracetam in the form of tablets. In step 2, dosage is increased to 1x250 plus 1x500 mg/d and in step 3 to 2x1000 mg/d levetiracetam. In step 4, levetiracetam is increased to 2x1500mg/d. In the fifth treatment step, patients will receive 2x1500 mg/d levetiracetam, and another AED will be added. The type and dosage of this add-on AED is according to the physician's preference, but in line with current clinical practice in the Netherlands.

Active Comparator: Valproic acid

Patients in this treatment arm will receive valproic acid monotherapy. The dosage depends on the specific treatment step, as indicated in the protocol. In step 1, patients will receive 2x500 mg/d valproic acid in the form of tablets. In step 2, dosage is increased to 1x250 plus 1x500 mg/d and in step 3 to 2x1000 mg/d valproic acid. In step 4, valproic acid dosage is increased to a maximum of 2x1250mg/d. In the fifth treatment step, patients will receive 2x1250mg valproic acid, and another AED will be added. The type and dosage of this add-on AED is according to the physician's preference, but in line with current clinical practice in the Netherlands.
