Researchers are evaluating the effectiveness and safety of a single inhaled dose of Staccato alprazolam compared to a placebo in quickly stopping prolonged seizure episodes in people aged 12 years and older with stereotypical prolonged seizures. This Phase 3 study aims to determine if the treatment can stop seizures within 90 seconds and prevent seizure recurrence for up to 2 hours after administration. Participants will receive one inhaled dose of either Staccato alprazolam or a placebo during the treatment period. The study is randomized, double-blind, and placebo-controlled, conducted at multiple outpatient centers. The intervention consists of a single administration designed to rapidly terminate seizure episodes. During the study, participants are closely monitored for seizure treatment success within 90 seconds and no seizure recurrence up to 2 hours post-treatment. Researchers will assess seizure control and safety outcomes throughout the treatment period. The study involves baseline assessments, caregiver involvement to observe seizures, and a focus on quick treatment response and safety over several hours following drug administration.
