Trial details

Who runs it

Original description

This study aims to evaluate the efficacy and safety of levetiracetam for the prevention of postoperative seizures in adult patients undergoing supratentorial brain tumor surgery. It is a multicenter, randomized, double-blind, placebo-controlled, parallel-group clinical trial. Eligible participants will be randomly assigned in a 1:1 ratio to receive levetiracetam or placebo, starting 1 hour before surgery and continuing for 3 months postoperatively. The primary outcome is the incidence of clinical seizures within 3 months after surgery. Secondary outcomes include subclinical seizures within 7 days and 3 months postoperatively, adverse events within 3 months, and health economic outcomes. The study aims to clarify the role of levetiracetam in the primary prevention of perioperative seizures in brain tumor patients and to provide evidence for rational use of antiseizure medications in neurosurgical practice.Read full original descriptionShow less

Perioperative Randomized Evaluation of leVetiracetam's Efficacy and Safety for Epilepsy Prevention in Neurosurgical Tumor Patients (PREVENT): A Multicenter, Randomized, Double-Blind, Placebo-Controlled Parallel Trial

This study aims to evaluate the efficacy and safety of levetiracetam for the prevention of postoperative seizures in adult patients undergoing supratentorial brain tumor surgery. It is a multicenter, randomized, double-blind, placebo-controlled, parallel-group clinical trial. Eligible participants will be randomly assigned in a 1:1 ratio to receive levetiracetam or placebo, starting 1 hour before surgery and continuing for 3 months postoperatively. The primary outcome is the incidence of clinical seizures within 3 months after surgery. Secondary outcomes include subclinical seizures within 7 days and 3 months postoperatively, adverse events within 3 months, and health economic outcomes. The study aims to clarify the role of levetiracetam in the primary prevention of perioperative seizures in brain tumor patients and to provide evidence for rational use of antiseizure medications in neurosurgical practice.
