Seizure Control as a New Metric in Assessing Efficacy of Tumor Treatment in Patients With Low Grade Glioma
An observational study of Brain Neoplasm and Low Grade Glioma, run by M.D. Anderson Cancer Center at 1 site in United States.
Trial summary
This study investigates how seizures can vary over time with changes in low grade gliomas and its treatments. This study may help doctors find symptoms or triggers of seizures earlier than normal, and ultimately earlier care or treatment for seizures. Read more about this study

About this study
This study investigates how seizures can vary over time with changes in low grade gliomas and its treatments. This study may help doctors find symptoms or triggers of seizures earlier than normal, and ultimately earlier care or treatment for seizures.

PRIMARY OBJECTIVE:
- To evaluate the rate of change of seizure frequency and the status of the tumor at each data collection point.
SECONDARY OBJECTIVES:
- To obtain sufficient number of patients' data in order to power the analysis to determine whether a change in seizure frequency correlates with tumor control.
II. Evaluate progression free survival and overall survival when compared with seizure control.
OUTLINE:
Patients complete a seizure assessment survey over 5 minutes at each clinic visit.
- Conditions
- Brain Neoplasm, Low Grade Glioma, Seizure Disorder
- Being tested
- Survey Administration

What is being measured
The primary outcome is the main question the study is designed to answer.
Rate of change of seizure frequency
Both average composite scores as well as individual question scores from the seizure survey will be evaluated. Will perform descriptive statistics to characterize the demographic and disease-related features of this population. Will perform regression analyses to the relationship of survey results to clinical and radiographic features. Cox regression analyses for other relevant post-hoc analyses may be performed.
Measured: Baseline to 2 years
Status of tumor
Radiographic information will be derived from brain MRIs performed on each patient at time of diagnosis, and subsequently at times of survey administration. Will perform descriptive statistics to characterize the demographic and disease-related features of this population. Will perform regression analyses to the relationship of survey results to clinical and radiographic features. Cox regression analyses for other relevant post-hoc analyses may be performed.
Measured: Up to 2 years
Secondary outcomes (3)
Patient data collection
Will obtain sufficient number of patients' data in order to power the analysis to determine whether a change in seizure frequency correlates with tumor control. Clinical information to be extracted from the medical record includes but not limited to; date of birth, gender, date of diagnosis, clinical symptoms referable to the brain tumor, functional status and age at diagnosis, treatments applied, dates of progression, and date of death. Radiographic information will be derived from brain MRIs performed on each patient at time of diagnosis, and subsequently at times of survey administration. Will perform descriptive statistics to characterize the demographic and disease-related features of this population.
Measured: Up to 2 years
Progression-free survival (PFS)
Will evaluate PFS when compared with seizure control.
Measured: Up to 2 years
Overall survival (OS)
Will evaluate OS when compared with seizure control.
Measured: Up to 2 years

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 5 inclusion and 4 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: under way, not looking for participants, as of the sponsor's last update on 7 Oct 2026. 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.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
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?
Rate of change of seizure frequency (time frame: Baseline to 2 years). The study lists 2 primary outcomes in all. 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 7 Oct 2026.
