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.
