Head-to-head evidence
Diastat vs Diazepam (Valtoco)
Same mechanism, same race: design-graded trial evidence for both assets, with the grading rationale shown. Grades describe the quality of the evidence, never the merits of either security.

Diastat
Marketed by Bausch Health
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.
Diazepam (Valtoco)
Marketed by Neurelis, Inc.
NCT02721069 · Phase 3 · completed
The study was open-label, nonrandomized, and had no placebo or active comparator, so it provides uncontrolled safety and treatment-exposure information rather than comparative evidence of effectiveness. Its primary endpoint was the number of participants receiving NRL-1 over 12 months, not a hard clinical seizure outcome, and no formal primary-endpoint comparison was applicable.
