NCT03953820 · Phase 1/2 · completed
The study randomized participants to treatment sequences and used Diastat as an active comparator, but it was open-label and small, with 31 randomized participants. Its primary endpoints were pharmacokinetic measures rather than clinical seizure outcomes, and the registry does not clearly report whether the primary comparison met its prespecified statistical criteria.
