Head-to-head evidence
Clobazam (Onfi) vs Diastat
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.

Clobazam (Onfi)
Marketed by Lundbeck LLC and partners
NCT00518713 · Phase 3 · completed
The study randomly assigned 238 participants to low-, medium-, or high-dose clobazam or placebo, with participants, care providers, and investigators masked to treatment. Its clinical primary endpoint—percent reduction in drop seizures—was statistically better than placebo for all three doses, supporting a strong evidence grade.
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.
