Levetiracetam Extended-Release Plus Stupp Protocol for Hypoxic IDH-Wildtype Glioblastoma

Glioblastoma (GBM) is the most common primary malignant brain tumor in adults and is associated with poor prognosis despite standard treatment with maximal safe resection followed by radiotherapy plus temozolomide (the Stupp regimen). Tumor hypoxia is associated with treatment resistance and poor clinical outcomes. This multicenter, prospective, controlled study aims to evaluate whether levetiracetam extended-release combined with the Stupp regimen improves progression-free survival and overall survival in patients with hypoxic IDH-wildtype glioblastoma while maintaining an acceptable safety profile. Eligible patients with newly diagnosed hypoxic IDH-wildtype glioblastoma will receive either levetiracetam extended-release plus the Stupp regimen or the standard Stupp regimen. Clinical efficacy, safety, and quality-of-life outcomes will be evaluated during follow-up.
