Researchers are evaluating the effectiveness of a single dose of Staccato alprazolam compared with a placebo to quickly stop prolonged seizure episodes in people aged 12 years and older with stereotypical prolonged seizures. The study aims to determine if the treatment can stop seizures within 90 seconds and prevent recurrence for up to 2 hours after administration. This is a phase 3, randomized, double-blind clinical trial sponsored by UCB Biopharma SRL. Participants are randomly assigned to receive one dose of either Staccato alprazolam or placebo by inhalation during the treatment period. The study involves a parallel-group design with one treatment administration. Participants are observed for the treatments effect on seizure cessation and recurrence for up to 6 hours. During the study, participants and their caregivers will be monitored for seizure activity and safety outcomes. Various assessments include measuring treatment success within 90 seconds and seizure recurrence at 2, 4, and 6 hours after treatment. Safety is tracked through adverse event monitoring, with follow-up extending to 19 weeks after treatment. The total participation duration is based on these assessments and monitoring periods.

This research aims to evaluate the long-term safety and tolerability of brivaracetam in children and adolescents with epilepsy, including those who participated in earlier studies or are newly enrolled in Japan with partial-onset seizures. The study also seeks to assess pharmacokinetic data in Japanese participants. The study is an open-label, single-arm, multicenter trial focusing on pediatric epilepsy treatment with brivaracetam. Participants will receive brivaracetam tablets or oral solution administered twice daily in two equal doses. Dosage varies based on weight up to 5 mgkgday for those weighing 11 to less than 20 kg, up to 4 mgkgday for those weighing 20 to less than 50 kg, and no more than 200 mgday. Directly enrolled participants in Japan will receive 1 to 4 mgkgday, not exceeding 200 mgday. The study includes long-term follow-up for up to 5 years. During the study, participants will be monitored for treatment-emergent adverse events, serious adverse events, and adverse events leading to discontinuation of the drug. Evaluations occur from Day 1 through safety visits over the 5-year period. Researchers will assess safety, tolerability, and pharmacokinetics. The total participation duration extends up to 5 years, with ongoing safety evaluations throughout this time.
