Validation of the Role of Levetiracetam for Newly Diagnosed GBM Patients

Study Purpose

Prospective, open-labeled, multicenter cohort trial for validation of the role of levetiracetam as a sensitizer of temozolomide in the treatment of newly diagnosed glioblastoma patients.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

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.

Eligible Ages 20 Years - 76 Years

Trial Details

Trial ID:

This trial id was obtained from, 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.


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.

Additional Details

  • I. Objectives 6 months progression-free survival (6m-PFS) 1.
Overall survival 2. Safety (adverse events) 3. Quality of life using EORTC module, 4. Cognitive function using NOPT module of our institution Genetic biomarker for predicting prognosis 1. Methylation status of MGMT promoter 2. IDH mutation 3. TERT mutation / ATRX status
  • II. Hypothesis 1.
Proof of concept
  • - With using of levetiracetam, there will be an improved survival with chemoradiotherapy with temozolomide compared to the group without using levetiracetam.
(superiority) 2. Safety
  • - It will be tolerable in this concept.
3. Genetic biomarker
  • - Methylation status of MGMT, IDH1 mutation, TERT mutation, and ATRX status will prove to be valid molecular markers of prognostic significance in newly diagnosed glioblastoma treated with the combination of levetiracetam.
  • III. Study Design/Clinical Plan 1.
Group I (prospective)
  • - Patients in this group are with newly diagnosed glioblastoma patients who are supposed to be treated with concurrent chemoradiotherapy (CCRT) and adjuvant chemotherapy with temozolomide (TMZ).
Patients in Group I will be given levetiracetam (LEV) from the beginning of treatment till after the adjuvant chemotherapy with TMZ is over. 2. Group II (historical group; using data base from KSNO multicenter study group)
  • IV. Treatment 1.
Levetiracetam: started with 250mg bid and is increased up to 500mg bid in perioperative period. During the 2 days of peri-operation, it is administered in intravenous form mixed in 150ml of normal saline. After immediate postoperative period, 500~1500mg bid is administered in per oral form according to patient's clinical condition. During the period of adjuvant chemotherapy with temozolomide, the dose not less than 500mg is administered unless there are serious side effects of levetiracetam. 2. Temozolomide based standard treatment: CCRT with temozolomide followed by 6cycles of adjuvant temozolomide RT with daily temozolomide (75 mg/m2/day, 7 days/week) from the first to the last day of radiotherapy), followed by six cycles of adjuvant temozolomide (150 to 200 mg/m2 for 5 days during each 28-day cycle).
  • V. Evaluation MR scans were performed before the first adjuvant treatment cycle and then every 3 months during the first year, and every 4 months during the second year.
Radiographic response is determined in comparison to the tumor measurement obtained at pretreatment baseline measurements as a reference and is categorized into four groups using new criteria proposed by the Response Assessment in Neuro-Oncology (RANO) working group.
  • VI. Statistical Plans Total sample size: 73 The size of sample is considered by assessment of PFS.
The number of event and statistical power was calculated on assumption of exponential distribution of the 7 months median PFS in the control group and 12 months median PFS in the treatment group. The expected sample size provides 80% of test power that can perceive 1.7 of hazard ration with 0.05 of type I error in comparative analysis of PFS at the time of 12 months of registering period (in equal entry pattern) and at 6 months of follow up period. Basis on this assumption, it is expected that 73 patients are needed in the treatment group, and 74 patients in the control group.
