PURPOSE: This study aimed to evaluate the efficacy and safety of intravenous perampanel (IV-PER) in routine clinical practice. METHODS: Patients who received IV-PER at Nagoya University Hospital or one of the 21 affiliated institutions between June 2024 and March 2025 were included. Indications for IV-PER included treatment for epileptic seizures, particularly acute symptomatic seizures, and prophylactic use before or after surgery. The primary endpoint was the seizure suppression rate within 7 days of treatment initiation, and the secondary endpoint was the incidence of adverse events (AEs). Clinical data were recorded daily, and blood tests were conducted within 2 weeks of administration. Enrolled patients were categorized into three groups based on the underlying etiology: cerebrovascular disease (CD), brain tumor (BT), and traumatic brain injury (TBI). Treatment efficacy and safety were assessed across these groups. RESULTS: Of the 237 patients, 74, 116, and 47 were classified into the CD, BT, and TBI groups, respectively. The overall seizure suppression rate within 7 days was 89.0 %. Rates by group were 87.8 % (CD), 96.6 % (BT), and 72.3 % (TBI). When stratified by indication, the rates were 99.3 % for prophylactic use, 69.4 % for focal seizures, and 74.4 % for generalized seizures. Regarding AEs, somnolence was reported in 3 patients and irritability in one. Laboratory abnormalities included anemia, elevated liver enzymes, elevated creatine kinase, and hyponatremia. A total of 71 patients experienced one of these. CONCLUSIONS: This large multicenter prospective registry demonstrates that IV-PER can be safely used for seizure management during the 7-day acute phase in real-world clinical settings.
