Head-to-head evidence
Clobazam (Onfi) vs Diazepam (Libervant)
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.
Diazepam (Libervant)
Marketed by Aquestive Therapeutics, Inc.
NCT03428360 · Phase 3 · completed
The study treated 130 participants with diazepam buccal film in a single open-label group, without randomization, blinding, or a control arm. Its primary outcomes were safety event counts rather than a controlled clinical comparison, so the findings cannot establish comparative treatment effectiveness.
